  1. Epicatechin and scopoletin-rich Morinda citrifolia leaf ameliorated leukemia via anti-inflammatory, anti-angiogenesis, and apoptosis pathways in vitro and in vivo
    Ahmadi N, Mohamed S, Sulaiman Rahman H, Rosli R
    J Food Biochem, 2019 07;43(7):e12868.
    PMID: 31353737 DOI: 10.1111/jfbc.12868
    The anti-leukemia mechanisms of Morinda citrifolia L. leaf extract were investigated on human Jurkat leukemia cells and in leukemia-induced BALB/c mice. The leukemia-induced mice were fed daily with the extract (100 or 200 mg/kg BW) and compared to ATRA (All-trans-retinoic-acid; 5 mg/kg BW). After 4 weeks' treatment, the extract (standardized to epicatechin and scopoletin), arrested Jurkat cell-cycle at the G0/G1 phase and activated the caspase-3 and caspase-8 (death-receptor extrinsic pathways). The extract dose-dependently reduced the blood and bone marrow myeloblasts levels of leukemia-induced mice; upregulated cancer suppressor genes CSF3, SOCS1, PTEN and TRP53; increased anti-inflammatory IL10 and IL4; downregulated anti-apoptotic or proliferation genes; decreased the pro-inflammatory NF-κβ; suppressed pro-angiogenesis VEGFA mRNA expressions, and restored the homeostatic immune or leukocytes levels. The extract directly ameliorated leukemia via cancer cells apoptosis, suppressed inflammation and angiogenesis; and mitigated bone marrow myeloblasts imbalance, without any observable toxicity on the animals. PRACTICAL APPLICATIONS: The scopoletin (coumarin) and epicatechin (flavonoid)-rich Morinda citrifolia (Noni) leaves may be used as functional food ingredient, vegetables, or dietary supplements to treat and suppress leukemia progression by directly killing the cancer cells and preventing new cancer cells development and bone marrow myeloblast imbalance in the bone marrow, without being toxic to normal cells. The M. citrifolia leaf extract suppressed inflammation, and potential metastasis by inhibiting new cancer-related blood vessel formation.

    Ahmed IA, Mikail MA
    Nutrition, 2024 Mar;119:112350.
    PMID: 38232577 DOI: 10.1016/j.nut.2023.112350
    The skin protects humans from pathogens, ultraviolet light, chemicals, mechanical, thermal, and physical injuries as well as hazardous substances. Other important roles of the skin include the regulation of several important physiological processes of the body, sensing stimuli, synthesis of vitamin D, and immune surveillance. However, aging, diseases and environmental conditions significantly change the skin's behavior and functioning. The treatment and prevention strategies for various skin diseases especially photoaging usually include topical treatment with medical cosmetology, active ingredients and other physical means of photoprotection. In recent times, however, there is an increasing consciousness about the role of diet and nutrition in skin health with certain dietary components emerging as an adequate alternative approach to alleviate and prevent both endogenous and exogenous aging symptoms. Therefore, this narrative review uniquely discusses the basic structure of the skin and also addresses common dermatological signs of damaged skin, the impacts of unhealthy diet habits on the skin, and the beneficial effects of some healthy diet habits on skin health. The information and data were collated from various literature databases and resources such as Science Direct, PubMed, Wiley, Springer, Taylor and Francis, Inflibnet, Scopus, Google, and Google Scholar using relevant keywords Medical Subject Headings (MeSH). In conclusion, diet and nutrition play essential roles in the optimum functioning of the human body, including the skin. Thus, certain diet habits such as less water intake, high-fat diet, refined sugar, and certain food additives are unhealthy and harmful to the skin while alternative healthy diet habits such as adequate water intake; consumption of antioxidants and polyphenolic-rich fruits, vegetables, nuts, and legumes; a low glycemic index diet; probiotics; and phytoestrogens should be adopted to enhance skin health.

    Awareness of recommendations for fruit and vegetable consumption has increased substantially over the last 20 years. In addition, fruits and vegetables such as pumpkin (Cucurbita moschata Duchesne) are good sources of many important nutrients, including potassium, vitamin C, folate, fibre, and numerous phytochemicals. Malaysia produces pumpkinits own, with considerably large areas of production comparable to its high global demand. However, in reality, there is a limitation in the commercial production as the local pumpkinis very much dependent on the market demand as the utilization has been limited to the consumption of fresh product. Thus, the objective of the study first initiative to provide the information about the pumpkinand second to investigatesthe opportunities on commercialized local pumpkinin Malaysia as by products despite various nutritious it is also listed as prophetic foods. The scientific research that covered a broad range of in vitro to in vivo studies on the by-products potentials of these fruits is also discussed in detail.The current review is an update for researchers to have a better understanding of the pumpkin, which simultaneously can provide awareness to enhance their commercial value and promote their utilization.Malaysia have potential to growth pumpkin instead of continuously importing. The daily consumption of pumpkins may provide various health benefits to human. Future investigation is needed to explore the potential of pumpkin as by products in order to increase its competitiveness and self-sufficiency.

  4. Highly sensitive and selective determination of malathion in vegetable extracts by an electrochemical sensor based on Cu-metal organic framework
    Al'Abri AM, Abdul Halim SN, Abu Bakar NK, Saharin SM, Sherino B, Rashidi Nodeh H, et al.
    J Environ Sci Health B, 2019;54(12):930-941.
    PMID: 31407615 DOI: 10.1080/03601234.2019.1652072
    This article demonstrates the first application of a copper-based porous coordination polymer (BTCA-P-Cu-CP) as a carbon paste electrode (CPE) modifier for the detection of malathion. The electrochemical behavior of BTCA-P-Cu-CP/CPE was explored using cyclic voltammetry (CV) while chrono-amperometry methods were applied for the analytical evaluation of the sensor performance. Under optimized conditions, the developed sensor exhibited high reproducibility, stability, and wide dynamic range (0.6-24 nM) with the limits of detection and sensitivity equal to 0.17 nM and 5.7 µAnMcm-1, respectively, based on inhibition signal measurement. Furthermore, the presence of common coexisting interfering species showed a minor change in signals (<4.4%). The developed sensor has been applied in the determination of malathion in spiked vegetable extracts. It exhibited promising results in term of fast and sensitive determination of malathion in real samples at trace level with recoveries of 91.0 to 104.4%. (RSDs < 5%, n = 3). A comparison of the two studied techniques showed that the HPLC technique is unable to detect malathion when the concentration is lower than 1.8 µM while 0.006 µM is detected with appropriate RSDs 0.2-5.2% (n = 3) by amperometric method. Due to the high sensitivity and selectivity, this new electrochemical sensor will be useful for monitoring trace malathion in real samples.

  5. Fulltext The Neglected Cestode Infection: Epidemiology of Hymenolepis Nana Infection Among Children in Rural Yemen
    Al-Mekhlafi HM
    Helminthologia, 2020 Dec;57(4):293-305.
    PMID: 33364898 DOI: 10.2478/helm-2020-0038
    Hymenolepis nana is the most common cestode reported in humans worldwide. It is prevalent among children in the tropics and subtropics, particularly in rural poor communities where sanitation is inadequate or lacking. This cross-sectional study aims to determine the prevalence and significant risk factors of H. nana infection among children in rural Yemen. Faecal samples were collected from 498 children and screened for intestinal parasites by using wet mount, formalin-ether concentration and Kato-Katz techniques. A pretested questionnaire was used to collect demographic, socioeconomic, housing condition, and personal hygiene information. Overall, 77.5 % (386/498) of the children were found to be infected by at least one intestinal parasite species. The overall prevalence of H. nana was 17.5 % (87/498). Multivariate analysis confirmed that an age of < 6 years (adjusted odds ratio [AOR] = 4.28; 95 % (confidence interval [CI] = 2.04, 8.98), presence of other family members infected with H. nana (AOR = 2.48; 95 % CI = 1.45, 4.24), living in the highlands (AOR = 2.87; 95 % CI = 1.56, 5.26), living in a house without improved toilet facilities (AOR = 2.19; 95 % CI = 1.23, 3.88), not washing vegetables before consumption (AOR = 2.11; 95 % CI = 1.06, 4.19), and not washing hands after defecation (AOR = 1.88; 95 % CI = 1.08, 3.27) were the key factors significantly associated with H. nana infection among the studied children. In conclusion, H. nana is prevalent among children in rural Yemen, particularly among preschool-aged children. Thus, an integrated and effective programme to control intestinal parasitic infections should include preschool-aged children. Such a programme should focus on providing health education on hygienic practices, providing adequate sanitation and improved sources of drinking water, and screening and treating other infected family members.

    Alam F, Islam MA, Kamal MA, Gan SH
    Curr Med Chem, 2018;25(39):5395-5431.
    PMID: 27528060 DOI: 10.2174/0929867323666160813222436
    Over the years, natural products have shown success as antidiabetics in in vitro, in vivo studies and clinical trials. Because natural product-derived drugs are more affordable and effective with fewer side-effects compared to conventional therapies, pharmaceutical research is increasingly leaning towards the discovery of new antidiabetic drugs from natural products targeting pathways or components associated with type 2 diabetes mellitus (T2DM) pathophysiology. However, the drug discovery process is very lengthy and costly with significant challenges. Therefore, various techniques are currently being developed for the preclinical research phase of drug discovery with the aim of drug development with less time and efforts from natural products. In this review, we have provided an update on natural products including fruits, vegetables, spices, nuts, beverages and mushrooms with potential antidiabetic activities from in vivo, in vitro and clinical studies. Synergistic interactions between natural products and antidiabetic drugs, and potential antidiabetic active compounds from natural products are also documented to pave the way for combination treatment and new drug discovery, respectively. Additionally, a brief idea of the drug discovery process along with the challenges that arise during drug development from natural products and the methods to conquer those challenges are discussed to create a more convenient future drug discovery process.

  8. Advances in postharvest technologies to extend the storage life of minimally processed fruits and vegetables
    Ali A, Yeoh WK, Forney C, Siddiqui MW
    Crit Rev Food Sci Nutr, 2018;58(15):2632-2649.
    PMID: 29072844 DOI: 10.1080/10408398.2017.1339180
    Minimally processed fresh produce is one of the fastest growing segments of the food industry due to consumer demand for fresh, healthy, and convenient foods. However, mechanical operations of cutting and peeling induce the liberation of cellular contents at the site of wounding that can promote the growth of pathogenic and spoilage microorganisms. In addition, rates of tissue senescence can be enhanced resulting in reduced storage life of fresh-cut fruits and vegetables. Chlorine has been widely adopted in the disinfection and washing procedures of fresh-cut produce due to its low cost and efficacy against a broad spectrum of microorganisms. Continuous replenishment of chlorine in high organic wash water can promote the formation of carcinogenic compounds such as trihalomethanes, which threaten human and environmental health. Alternative green and innovative chemical and physical postharvest treatments such as ozone, electrolyzed water, hydrogen peroxide, ultraviolet radiation, high pressure processing, and ultrasound can achieve similar reduction of microorganisms as chlorine without the production of harmful compounds or compromising the quality of fresh-cut produce.

    Amoah J, Said S, Rampal L, Manaf R, Ibrahim N, Owusu-Agyei S, et al.
    PLoS One, 2021;16(11):e0259581.
    PMID: 34762713 DOI: 10.1371/journal.pone.0259581
    BACKGROUND: Cardiovascular diseases (CVDs) are the number cause of death worldwide. In Ghana CVD has been the leading cause of death since 2001. The prevalence of CVD risk factors among adolescents in Ghana has been increasing. This study seeks to develop, implement and evaluate the effects of a behavioral modification intervention program to reduce CVD risk factors among secondary school students in Brong Ahafo, Ghana.

    METHODS: A cluster-randomized controlled trial was conducted with schools as clusters over a period of six-months with pre and post intervention evaluations. Participants were public secondary school students (14-19 years) from four schools in Brong Ahafo, Ghana. Students in the intervention group were trained by the researchers whereas those of the control group received no intervention. The intervention included health education and physical activity modules. Follow-up data using same questionnaire were collected within two weeks after the intervention was completed. Intention-to-treat analysis was performed after replacing missing values using the multiple imputation method. The generalized linear mixed model (GLMM) was used to assess the effects of the intervention study.

    RESULTS: The GLMM analyses showed the intervention was effective in attaining 0.77(p<0.001), 0.72(p<0.001), 0.47(p<0.001), 0.56(p<0.001), and 0.39(p = 0.045) higher total physical activity, fruits, vegetables, seafood, and water scores respectively for the intervention group over the control group. The intervention was also significant in reducing -0.15(p<0.001),-0.23(p<0.001),-0.50(p<0.001),-0.32(p<0.001),-0.90(p<0.001),-0.87(p<0.001),-0.38(p<0.001), -0.63(p<0.001), -1.63(p<0.001), 0.61(p<0.001), and -1.53(p = 0.005) carbohydrates, fats and oils, fried eggs, fried chicken, carbonated drinks, sugar, sweet snacks, salted fish, weight, BMI, and diastolic BP. The odds of quitting alcohol use in the intervention group were 1.06 times more than the control group. There was no significant effect on reducing smoking and systolic BP.

    CONCLUSION: There is an urgent need for the intervention program to be integrated into the existing curriculum structure of secondary school schools. Implementing the intervention will allow for longer and more consistent impact on the reduction of CVD risk factors among secondary school students.

  10. Fulltext Overviews of Biological Importance of Quercetin: A Bioactive Flavonoid
    Anand David AV, Arulmoli R, Parasuraman S
    Pharmacogn Rev, 2017 1 14;10(20):84-89.
    PMID: 28082789 DOI: 10.4103/0973-7847.194044
    Antioxidants are substances that may protect cells from the damage caused by unstable molecules such as free radicals. Flavonoids are phenolic substances widely found in fruits and vegetables. The previous studies showed that the ingestion of flavonoids reduces the risk of cardiovascular diseases, metabolic disorders, and certain types of cancer. These effects are due to the physiological activity of flavonoids in the reduction of oxidative stress, inhibiting low-density lipoproteins oxidation and platelet aggregation, and acting as vasodilators in blood vessels. Free radicals are constantly generated resulting in extensive damage to tissues leading to various disease conditions such as cancer, Alzheimer's, renal diseases, cardiac abnormalities, etc., Medicinal plants with antioxidant properties play a vital functions in exhibiting beneficial effects and employed as an alternative source of medicine to mitigate the disease associated with oxidative stress. Flavonoids have existed over one billion years and possess wide spectrum of biological activities that might be able to influence processes which are dysregulated in a disease. Quercetin, a plant pigment is a potent antioxidant flavonoid and more specifically a flavonol, found mostly in onions, grapes, berries, cherries, broccoli, and citrus fruits. It is a versatile antioxidant known to possess protective abilities against tissue injury induced by various drug toxicities.

    PMID: 24800383 MyJurnal
    Introduction: The use of email and website as channels for workplace health
    information delivery is not fully explored. This study aims to describe the
    rationale, design, and baseline findings of an email-linked website intervention
    to improve modifiable cancer risk factors. Methods: Employees of a Malaysian
    public university were recruited by systematic random sampling and randomised
    into an intervention (n=174) or control group (n=165). A website was developed
    for the intervention and educational modules were uploaded onto the website.
    The intervention group received ten consecutive weekly emails with hypertext
    links to the website for downloading the modules and two individual phone
    calls as motivational support whilst the control group received none. Diet,
    lifestyle, anthropometric measurements, psychosocial factors and stages of change
    related to dietary fat, fruit and vegetable intake, and physical activity were
    assessed. Results: Participants were predominantly female and in non-academic
    positions. Obesity was prevalent in 15% and 37% were at risk of co-morbidities.
    Mean intake of fats was 31%, fruit was ~1 serving/day and vegetable was <1
    serving/day. Less than 20% smoked and drank alcohol and about 40% were
    physically inactive. The majority of the participants fell into the Preparation
    stage for decreasing fat intake, eating more fruit and vegetables, and increasing
    physical activity. Self-efficacy and perceived benefits were lowest among participants in the Precontemplation/Contemplation stage compared to the Preparation
    and Action/Maintenance stages. Conclusion: Baseline data show that dietary and
    lifestyle practices among the employees did not meet the international guidelines
    for cancer prevention. Hence the findings warrant the intervention planned.

    PMID: 24525479 DOI: 10.1038/srep04101
    Currently, information on prevalence of soil-transmitted helminth (STH) infections among different tribes of Orang Asli (aboriginal) is scarce in Malaysia. The present study is a cross-sectional study aimed at determining the factors associated with the prevalence of STH infections among the Proto-Malay, Negrito and Senoi tribes. Faecal samples were collected from 500 participants and socioeconomic data was collected via pre-tested questionnaire. All samples were processed using formalin-ether sedimentation and Wheatley's trichrome staining. Trichuris trichiura (57%) was the most common STH seen among the participants, followed by Ascaris lumbricoides (23.8%) and hookworm (7.4%). Trichuriasis and ascariasis showed an age-dependency relationship; significantly higher rates were observed among Senois who aged <15 years. Likewise, Negritos also showed an age-dependency association with ascariasis affecting mainly the under 15 years old individuals. Multivariate logistic regression model indicated the following predictors of trichuriasis among these communities; being aged <15 years, consuming raw vegetables, belonging to a large household members (≥8) and earning low household income (

    Int J Cancer, 1998 Jul 17;77(2):228-35.
    PMID: 9650558 DOI: 10.1002/(SICI)1097-0215(19980717)77:2<228::AID-IJC
    We interviewed 282 histologically confirmed cases of nasopharyngeal carcinoma (NPC) in Chinese residents of Selangor and the Federal Territory, Malaysia, and an equal number of Chinese age-, sex-, and length-of-residence-matched controls sampled from the general population. Consumption of 55 dietary items during childhood, and 5 years pre-diagnosis of NPC, was analyzed by univariate and multivariate methods. Four salted preserved foods (fish, leafy vegetables, egg and root), fresh pork/beef organ meats and beer and liquor consumption exhibited strong positive associations, and 4 vegetable/fruit combinations strong negative associations with NPC. Factor analysis and multivariable modeling using estimated factor scores strongly supported separate effects on NPC of vegetables/fruits, salted preserved foods, pork/beef organ meats and beer/liquor consumption. Multivariable modeling associated NPC most clearly with high consumption of salted fish, salted eggs, pork/beef liver and beer and low consumption of Chinese flowering cabbage, oranges/tangerines and shrimp. A strong residual association of social class with NPC remained after adjustment for diet, which is consistent with a substantial role for non-dietary environmental factors.

  15. Soil-to-root vegetable transfer factors for (226)Ra, (232)Th, (40)K, and (88)Y in Malaysia
    Asaduzzaman Kh, Khandaker MU, Amin YM, Bradley DA, Mahat RH, Nor RM
    J Environ Radioact, 2014 Sep;135:120-7.
    PMID: 24814722 DOI: 10.1016/j.jenvrad.2014.04.009
    Soil-to-plant transfer factors (TFs) are of fundamental importance in assessing the environmental impact due to the presence of radioactivity in soil and agricultural crops. Tapioca and sweet potato, both root crops, are popular foodstuffs for a significant fraction of the Malaysian population, and result in intake of radionuclides. For the natural field conditions experienced in production of these foodstuffs, TFs and the annual effective dose were evaluated for the natural radionuclides (226)Ra, (232)Th, (40)K, and for the anthropogenic radionuclide (88)Y, the latter being a component of fallout. An experimental tapioca field was developed for study of the time dependence of plant uptake. For soil samples from all study locations other than the experimental field, it has been shown that these contain the artificial radionuclide (88)Y, although the uptake of (88)Y has only been observed in the roots of the plant Manihot esculenta (from which tapioca is derived) grown in mining soil. The estimated TFs for (226)Ra and (232)Th for tapioca and sweet potato are very much higher than that reported by the IAEA. For all study areas, the annual effective dose from ingestion of tapioca and sweet potato are estimated to be lower than the world average (290 μSv y(-1)).

  16. Nonmeat Protein Alternatives as Meat Extenders and Meat Analogs
    Asgar MA, Fazilah A, Huda N, Bhat R, Karim AA
    Compr Rev Food Sci Food Saf, 2010 Sep;9(5):513-529.
    PMID: 33467834 DOI: 10.1111/j.1541-4337.2010.00124.x
      The direct consumption of vegetable proteins in food products has been increasing over the years because of animal diseases, global shortage of animal protein, strong demand for wholesome and religious (halal) food, and economic reasons. The increasing importance of legume and oilseed proteins in the manufacturing of various functional food products is due to their high-protein contents. However, the greatest obstacle to utilizing these legumes and oilseeds is the presence of antinutrients; but these antinutrients can be successfully removed or inactivated by employing certain processing methods. In contrast, the potential negative impact of the antinutrients is partially balanced by the fact that they may have a health-promoting role. Legumes and oilseeds provide well-balanced amino acid profiles when consumed with cereals. Soybean proteins, wheat gluten, cottonseed proteins, and other plant proteins have been used for texturization. Texturized vegetable proteins can extend meat products while providing an economical, functional, and high-protein food ingredient or can be consumed directly as a meat analog. Meat analogs are successful because of their healthy image (cholesterol free), meat-like texture, and low cost. Mycoprotein is fungal in origin and is used as a high-protein, low-fat, health-promoting food ingredient. Mycoprotein has a good taste and texture. Texturized vegetable proteins and a number of mycoprotein products are accepted as halal foods. This article summarizes information regarding the molecular, nutritional, and functional properties of alternative protein sources to meat and presents current knowledge to encourage further research to optimize the beneficial effects of alternative protein sources.

  17. Fulltext Genome sequencing and analysis of Salmonella enterica subsp. enterica serovar Stanley UPM 517: Insights on its virulence-associated elements and their potentials as vaccine candidates
    Ashari KS, Roslan NS, Omar AR, Bejo MH, Ideris A, Mat Isa N
    PeerJ, 2019;7:e6948.
    PMID: 31293824 DOI: 10.7717/peerj.6948
    Salmonella enterica subsp. enterica serovar Stanley (S. Stanley) is a pathogen that contaminates food, and is related to Salmonella outbreaks in a variety of hosts such as humans and farm animals through products like dairy items and vegetables. Despite the fact that several vaccines of Salmonella strains had been constructed, none of them were developed according to serovar Stanley up to this day. This study presents results of genome sequencing and analysis on our S. Stanley UPM 517 strain taken from fecal swabs of 21-day-old healthy commercial chickens in Perak, Malaysia and used Salmonella enterica subsp. enterica serovar Typhimurium LT2 (S. Typhimurium LT2) as a reference to be compared with. First, sequencing and assembling of the Salmonella Stanley UPM 517 genome into a contiguous form were done. The work was then continued with scaffolding and gap filling. Annotation and alignment of the draft genome was performed with S. Typhimurium LT2. The other elements of virulence estimated in this study included Salmonella pathogenicity islands, resistance genes, prophages, virulence factors, plasmid regions, restriction-modification sites and the CRISPR-Cas system. The S. Stanley UPM 517 draft genome had a length of 4,736,817 bp with 4,730 coding sequence and 58 RNAs. It was discovered via genomic analysis on this strain that there were antimicrobial resistance properties toward a wide variety of antibiotics. Tcf and ste, the two fimbrial virulence clusters related with human and broiler intestinal colonizations which were not found in S. Typhimurium LT2, were atypically discovered in the S. Stanley UPM 517 genome. These clusters are involved in the intestinal colonization of human and broilers, respectively. There were seven Salmonella pathogenicity islands (SPIs) within the draft genome, which contained the virulence factors associated with Salmonella infection (except SPI-14). Five intact prophage regions, mostly comprising of the protein encoding Gifsy-1, Fels-1, RE-2010 and SEN34 prophages, were also encoded in the draft genome. Also identified were Type I-III restriction-modification sites and the CRISPR-Cas system of the Type I-E subtype. As this strain exhibited resistance toward numerous antibiotics, we distinguished several genes that had the potential for removal in the construction of a possible vaccine candidate to restrain and lessen the pervasiveness of salmonellosis and to function as an alternative to antibiotics.

    Mayonnaise and salad dressing are fast becoming popular condiments for Malaysian. The aim of this study was to
    obtain the nutritional composition of mayonnaise and salad dressing commercially available in the Malaysian market.
    The data will be used to update the Malaysian Food Composition Database which was last updated in 1997. A total of
    six brands from each type of mayonnaise and salad dressing were sampled from local supermarkets in the Klang Valley
    and analysed using standard methods. The validity of test data was monitored with the application of internal quality
    controls in line with the requirements of ISO 17025. The energy contents of mayonnaise and salad dressings were up to
    626.40 kcal/100 g. Our findings were also in agreement with the energy labelling on the packaging. Sodium was high in
    mayonnaise and salad dressing because it is used in the final mixture of both condiments to improve their characteristics
    for certain reasons. Mayonnaise and salad dressing have been identified as potent sources of vitamin A and vitamin
    E and both condiments were found to contain high levels of these antioxidants. It can be concluded that this study are
    useful not only in providing information on the nutritional content of several commercial types of mayonnaise and salad
    dressing, but also in improving the public understanding of healthy food choices.

    The aim of this study was to determine hydrolytic stability [acid value (AV)] and oxidative stability [peroxide value (PV) and conjugated dienes (CD)] of selected blended oils during potato frying. The blended oils were prepared by blending palm oil with corn oil (POCO), sesame oil (POSO) and rice bran oil (PORBO). Blended vegetable oils were prepared in a ratio of 1 to 1 (v/v) and tested for 0, 10 and 20 times after frying potato. AV and PV were determined by titration method, while CD was determined using the spectrophotometric method. Increasing frequency of oil frying contributed to increased level of AV in all blended oils. PVs were increased in all samples, with most noticeable increment observed in POSO, followed by PORBO and POCO. CD levels of the blended oils were also increased after 20 times of potato frying compared with the unused oil and after 10 times of frying. POCO was the most stable oil in terms of hydrolytic and oxidative stabilities. It is most suitable for deep-fat frying of potato chips and industrial application.
