    BACKGROUND: Recycled oil has emerged as a significant food safety issue and poses a major threat to public health. To date, very limited studies have been conducted aiming to detect the adulteration of used and recycled palm olein in refined, bleached and deodorized palm olein (RBDPO). In the present study, oil samples that underwent controlled heating and deep-frying studies were refined using the common oil refining procedure to simulate the production of recycled oil. Polymerized triacylglycerol (PTG), oxidized monomeric triacylglycerols (oxTAGs), such as epoxy, keto and hydroxy acids, and caprylic acid have been proposed as potential indicators for tracking the adulteration of recycled oil.

    RESULTS: For PTG, triacylglycerol oligomers and dimers showed a significant increase (P

    3-Monochloropropane-1,2-diol (3-MCPD) esters and glycidyl esters (GE) are heat-induced contaminants which form during oil refining process, particularly at the high temperature deodorization stage. It is worth to investigate the content of 3-MCPD and GE in fries which also involved high temperature. The content of 3-MCPD esters and GE were monitored in fries. The factors that been chosen were temperature and duration of frying, and different concentration of salt (NaCl). The results in our study showed that the effect was in the order of concentration of sodium chloride

    The method of liquid chromatographic tandem mass spectrometry was utilized and modified to confirm and quantify acrylamide in heating cooking oil and animal fat. Heating asparagine with various cooking oils and animal fat at 180°C produced varying amounts of acrylamide. The acrylamide in the different cooking oils and animal fat using a constant amount of asparagine was measured. Cooking oils were also examined for peroxide, anisidine and iodine values (or oxidation values). A direct correlation was observed between oxidation values and acrylamide formation in different cooking oils. Significantly less acrylamide was produced in saturated animal fat than in unsaturated cooking oil, with 366ng/g in lard and 211ng/g in ghee versus 2447ng/g in soy oil, followed by palm olein with 1442ng/g.

    The technique of Fourier transform infrared spectroscopy is widely used to generate spectral data for use in the detection of food contaminants. Monochloropropanediol (MCPD) is a refining process-induced contaminant that is found in palm-based fats and oils. In this study, a chemometric approach was used to evaluate the relationship between the FTIR spectra and the total MCPD content of a palm-based cooking oil. A total of 156 samples were used to develop partial least squares regression (PLSR), artificial neural network (nnet), average artificial neural network (avNNET), random forest (RF) and cubist models. In addition, a consensus approach was used to generate fusion result consisted from all the model mentioned above. All the models were evaluated based on validation performed using training and testing datasets. In addition, the box plot of coefficient of determination (R2), root mean square error (RMSE), slopes and intercepts by 100 times randomization was also compared. Evaluation of performance based on the testing R2 and RMSE suggested that the cubist model predicted total MCPD content with the highest accuracy, followed by the RF, avNNET, nnet and PLSR models. The overfitting tendency was assessed based on differences in R2 and RMSE in the training and testing calibrations. The observations showed that the cubist and avNNET models possessed a certain degree of overfitting. However, the accuracy of these models in predicting the total MCPD content was high. Results of the consensus model showed that it slightly improved the accuracy of prediction as well as significantly reduced its uncertainty. The important variables derived from the cubist and RF models suggested that the wavenumbers corresponding to the MCPDs originated from the -CH=CH2 or CH=CH (990-900 cm-1) and C-Cl stretch (800-700 cm-1) regions of the FTIR spectrum data. In short, chemometrics in combination with FTIR analysis especially for the consensus model represent a potential and flexible technique for estimating the total MCPD content of refined vegetable oils.

  5. Effect of amino acids and frequency of reuse frying oils at different temperature on acrylamide formation in palm olein and soy bean oils via modeling system
    Daniali G, Jinap S, Sanny M, Tan CP
    Food Chem, 2018 Apr 15;245:1-6.
    PMID: 29287315 DOI: 10.1016/j.foodchem.2017.10.070
    This work investigated the underlying formation of acrylamide from amino acids in frying oils during high temperatures and at different times via modeling systems. Eighteen amino acids were used in order to determine which one was more effective on acrylamide production. Significantly the highest amount of acrylamide was produced from asparagine (5987.5µg/kg) and the lowest from phenylalanine (9.25µg/kg). A constant amount of asparagine and glutamine in palm olein and soy bean oils was heated up in modelling system at different temperatures (160, 180 and 200°C) and times (1.5, 3, 4.5, 6, 7.5min). The highest amount of acrylamide was found at 200°C for 7.5min (9317 and 8511µg/kg) and lowest at 160°C for 1.5min (156 and 254µg/kg) in both frying oils and both amino acids. Direct correlations have been found between time (R2=0.884), temperature (R2=0.951) and amount of acrylamide formation, both at p<0.05.

    MyJurnal
    The influence of superheated steam cooking on fat and fatty acid composition of chicken sausage were investigated at various temperatures (150, 200, and 250°C) with different time domains (2-6 min). It has been found that the fat content of raw sample was higher than that of all cooked samples. The total fat content of cooked sample, showed a linear decreasing with time at all investigated temperatures. Superheated steam produce changes in saturated fatty acid (SFA), monounsaturated fatty acid (MUFA), and polyunsaturated fatty acid (PUFA) in which their values were found to decrease in cooked samples. When different cooking conditions (temperature, time) were applied, the fatty acids were decreased as the time and temperature increased. The PUFA and MUFA were less prone to decrease at 150°C, while at this temperature there was a remarkable loss in SFA content. This cooking method considerably reduced the level of fat and SFA which have a positive effect on health. In addition it could imply a great choice for consumers to choose the healthier technique for cooking food.

    MyJurnal
    An experimental study was performed to determine the drying characteristics of dried papaya using different drying methods. They were dried using several methods, such as sun drying, solar drying, oven drying, and microwave drying. The effects of different operating conditions on physical quality attributes were investigated. The papaya were cut into different thicknesses and cooked in sugar syrup with different sugar concentration for 24 hours. Three different temperature settings were used in oven and microwave drying. The drying curve and drying rate of each method, temperature, sample
    thickness and sugar concentration were studied. The drying times were found as in 6-15 minutes, 5 to 11 h, 10 to 18 h, and 14 to 23 h for the microwave, oven, sun and solar drying, respectively. The drying time increased with the increase of sample thickness and sugar concentration, as well as with the decrease of the drying temperature. In this study, quality attributes like colours and textural property of dried papaya were explored. Among the various methods of the drying characteristics
    of papaya halwa, oven drying was preferred with the optimum sample in 5 mm thickness and at the air temperature of 70ºC as it saved up to 40% of the drying time as compared to other methods, except microwave, and produced acceptable physical quality of product.

  8. Managing the hazardous waste cooking oil by conversion into bioenergy through the application of waste-derived green catalysts: A review
    Hosseinzadeh-Bandbafha H, Li C, Chen X, Peng W, Aghbashlo M, Lam SS, et al.
    J Hazard Mater, 2022 02 15;424(Pt C):127636.

    Waste cooking oil (WCO) is a hazardous waste generated at staggering values globally. WCO disposal into various ecosystems, including soil and water, could result in severe environmental consequences. On the other hand, mismanagement of this hazardous waste could also be translated into the loss of resources given its energy content. Hence, finding cost-effective and eco-friendly alternative pathways for simultaneous management and valorization of WCO, such as conversion into biodiesel, has been widely sought. Due to its low toxicity, high biodegradability, renewability, and the possibility of direct use in diesel engines, biodiesel is a promising alternative to mineral diesel. However, the conventional homogeneous or heterogeneous catalysts used in the biodiesel production process, i.e., transesterification, are generally toxic and derived from non-renewable resources. Therefore, to boost the sustainability features of the process, the development of catalysts derived from renewable waste-oriented resources is of significant importance. In light of the above, the present work aims to review and critically discuss the hazardous WCO application for bioenergy production. Moreover, various waste-oriented catalysts used to valorize this waste are presented and discussed.

    PMID: 37484517 DOI: 10.12688/f1000research.126890.2
    A systematic literature review was conducted to summarize the overall thermal performance of different gasified cooking stoves from the available literature. For this purpose, available studies from the last 14 years (2008 to 2022) were searched using different search strings. After screening, a total of 28 articles were selected for this literature review. Scopus, Google Scholar, and Web of Science databases were used as search strings by applying "Gasifier cooking stove" AND "producer gas cooking stove" AND "thermal performance" keywords. This review uncovers different gasified cooking stoves, cooking fuels, and fabrication materials besides overall thermal performances. The result shows that the overall thermal performance of different gasified cooking stoves was 5.88% to 91% depending on the design and burning fuels. The premixed producer gas burner with a swirl vane stove provided the highest overall thermal performance range, which was 84% to 91%, and the updraft gasified stove provided the lowest performance, which was 5.88% to 8.79%. The result also demonstrates that the wood pellets cooking fuel provided the highest thermal performance and corn straw briquette fuel provided the lowest for gasified cooking stoves. The overall thermal performance of wood pellets was 38.5% and corn straw briquette was 10.86%.

    A total of 112 burger patties (35 beef burger patties, 39 chicken burger patties and 38 fish burger patties) which are commercially available at retail level were investigated for the presence and number of Listeria monocytogenes. These samples were analyzed using MPN-PCR method and conventional culturing methods. L. monocytogenes was detected in 33.3% of chicken burger patties, 22.9% of beef patties, and 10.5% of fish patty samples. From all contaminated raw burger patties, the estimated count of L. monocytogenes was ranged from 3 to 75 MPN/g. The results suggest that burger act as a potential source of listeriosis if the contaminated burger patty is consumed without adequate cooking. The risk associated with consumption of these samples was found to be high particularly for processed food at retail level in Malaysia. Therefore, food manufacturers play an important role in monitoring the manufacturing process and conduct a periodical surveillance on microbiological quality assessment on the processing plants. Besides, there is a need to increase awareness of consumers and food handlers to practice proper cooking of the burger patties before the point of consumption, to reduce the risk of listeria infection.

    Bacillus cereus (B. cereus) isolates are toxigenic and can cause food poisoning. Cooked rice is
    a potentially hazardous food, especially in tropical countries. The aim of this study was to determine the prevalence of B. cereus and B. thuringiensis in raw and cooked rice marketed in Selangor, Malaysia. In this research combination of Most Probable Number - Polymerase Chain Reaction (MPN-PCR) was used to detect gyrB gene in B. cereus and B. thuringiensis. Five local varieties of raw rice samples were negative for B. thuringiensis but all (100%) were positive for B. cereus. A total of 115 cooked rice samples (nasi lemak, nasi briyani, nasi ayam and nasi putih) were studied for the presence of B. cereus and B. thuringiensis. Nasi ayam was found to have the highest prevalence (100%) of B. cereus compared to nasi putih (76.2%) and nasi lemak (70.4%). Nasi briyani had the lowest prevalence (50%) of B. cereus. The frequencies of B. thuringiensis were found to be 10, 30 and 35.2 % in nasi putih and nasi ayam, nasi briyani and nasi lemak, respectively. The range of B. cereus and B. thuringiensis in the samples was from < 3 to 1100 MPN/g in different samples. Maximum number of B. cereus was observed in nasi lemak, nasi briyani and nasi putih ( > 1100 MPN/g) while nasi ayam showed less contamination (460 MPN/g) with B. cereus which was significantly different (P < 0.05 ) from others. The number of B. thuringiensis in nasi lemak, nasi briyani, nasi putih and nasi ayam were found to be >1100, 93, 9.2 and 3.6 MPN/g, respectively.

    Escherichia coli O157:H7 is a major food-borne pathogen that has resulted in numerous
    outbreaks around the world. Widespread distribution of the organism in various ecological
    niches impedes the control measures. This study aimed to detect and quantify E. coli O157:H7
    in beef sold in wet markets and hypermarkets in Malaysia and to determine the risk of E. coli
    O157:H7 infection linked to consumption of beef. The rfbO157 and flicH7 primers targeted on
    somatic antigen (O157) and flagellar antigen (H7) respectively of E. coli O157:H7 was used for
    the MPN-PCR method. A total of 99 beef samples were collected from local wet markets and
    hypermarkets. The highest E. coli O157:H7 contamination rate was observed in beef samples
    collected from wet markets (89.50%), whereas the contamination rate in hyper market A and B
    were compratively low (35.35 and 20% respectively). However, the microbial load was highest
    in the beef samples from hypermarket A (1100 MPN/g) while E. coli O157:H7 bacterial load
    in beef samples from hypermarket B and wet market ranged from 3 to 93 MPN/g and 3 to 240
    MPN/g, respectively. Using the Quantitative Microbial Risk Assessment (QMRA) approach
    the risk was estimated incorporating the findings of the prevalence study and predictions
    based on home storage, cooking and consumption patterns. Three different exposure pathways
    were investigated to estimate the risk associated with contaminated beef and Monte Carlo
    simulation was used to determine the level of uncertainty. The developed model predicated that
    consumption of contaminated beef can be accountable for 1.83E+06 E. coli O157:H7 cases per
    year in Malaysia. The reliability of the model, data gaps and further research needs, is discussed.
    Through continuous improvement Quantitative Microbial Risk Assessment provides valuable
    insight into controlling and prevention strategies.

    Mushrooms are well known to be healthy because they are low in calories, fat and cholesterol level but rich in vitamin and other essential nutrients. The grey oyster mushroom, Pleurotus sajor-caju (PSC), is a common edible mushroom and is now grown commercially around the world for food and food products. The ability of PSC in changing physical characteristics and sensory properties of beef patty formulated with this fungus were investigated. Result shows beef patty added with 50% ground PSC recorded the highest concentration total dietary fibre (TDF) at 9.95 g/100g compared to beef patty containing 25% of PSC (7.00 g/100g) and control (3.90g/100g). Beef which was replaced with 25% of PSC, recorded the highest cooking yield (76.62%) and moisture retention (59.80%) respectively. On the other physical traits, beef patty containing 25%

  15. Nutritional composition and sensory properties of oyster mushroom-based patties packed with biodegradable packaging
    Wan Rosli W, Solihah M
    Sains Malaysiana, 2014;43:65-71.
    The increase use of synthetic packaging films in food products has led to serious environmental problems due to their total non-biodegradability property. Nutrient composition and sensory acceptability of chicken patties formulated with various levels of Pleurotus sajor-caju popularly known as grey oyster mushroom (oM) and wrapped with degradable plastic were studied. The chicken patties were formulated with either 0, 25 or 50% of fresh oM. The results showed that chicken patty formulated with 25% PSC has protein content of 17.46% lower than the control patty which had 18.13% but it was not significant (p>0.05). After storage, cooked chicken patty formulated with 25% oM had protein content of 21.53% lower than the control patty (23 .90%) but it was not significant (p>0 .05). However, incorporation of oM in chicken patties resulted in decreasing of fat content significantly (p0 .05) from 15.58 (control) to 13.33% after storage. On the other nutrient, the concentration of f3-glucan were detected at values ranged between 0.70 and 0.76 (g1100 g) after 6 month. Other results showed that patty formulated with 25% oM received the highest scores for all attributes except for aroma. Meanwhile, patty prepared with 50% oM received the highest score of aroma attribute after 6 month of storage. However, the score values for all attributes of all oM-based patties were not statistically different with control patty (p> 0.05). In conclusion, the addition of oM at 25% can be recommended for the purpose of lowering fat content while keeping protein and f3-glucan unchanged without jeopardizing sensorial properties. This investigation therefore, suggested that biodegradable plastic can be used in packing any type of processed meat-based products.

    This study provides a comparative analysis of the effects of pre-slaughter penetrative and non-penetrative stunning and post-slaughter stunning on meat quality attributes in longissimus lumborum (LL) and semitendinosus (ST) muscles in heifers. Ten animals were assigned to each of four treatment groups: i) animals were subjected to conventional Halal slaughter (a clean incision through the structures at the front of the upper neck - the trachea, oesophagus, carotid arteries and jugular veins) and post-cut penetrating mechanical stun within 10 to 20 s of the neck cut (Unstunned; US); ii) high power non-penetrating mechanical stunning followed by the neck cut (HPNP); iii) low power non-penetrating mechanical stunning followed by the neck cut (LPNP); and iv) penetrative stunning using a captive bolt pistol followed by the neck cut (P). For each carcass, muscle samples were removed within 45 min of slaughter, portioned and analysed for pH, cooking loss, water holding capacity (WHC), tenderness (WBS), lipid oxidation (TBARS) and color, over a two week storage period. Stunning did not affect pH and cooking loss. Significant differences in water holding capacity, tenderness, lipid oxidation and color were present at different storage time points. HPNP stunning resulted in lower WHC and color values, particularly lightness (L*), higher TBARS values and peak force values compared with those stunned using LPNP, P and US. These adverse effects on quality were mostly encountered in the ST muscle. In conclusion, the meat quality achieved using P, LPNP and US treatments was comparable, and no treatment stood out as considerably better than another.

    Black jelly mushroom (Auricularia polytricha) is a well-known Chinese traditional food that has therapeutic effects. This study evaluated the effects of different cooking methods (boiling, steaming, microwaving, and stir-frying) on the physicochemical characteristics (i.e., total phenolic content, antioxidants, α,α-diphenyl-β-picryl-hydrazyl [DPPH] free radical scavenging, and ferric reducing antioxidant power [FRAP]) along with color, texture, moisture, and sensory properties of black jelly mushrooms. Lightness (L*) was significantly lower for the stir-frying method (29.93) compared to the control (34.62). Stir-fried mushrooms had significantly lower firmness force (texture) and moisture content (80.13 N and 61.98%, respectively) compared to the control (2000.37 N and 86.52%). The steaming method contributed significantly higher total phenolic content (11.23 mg gallic acid equivalents/g) and antioxidant activity measured using the FRAP (33.54 mg Trolox equivalents/g) and DPPH (90.41% inhibition) assays compared to the respective controls.

    Elderly are exposed to physical impairment. This has a strong impact on their daily activities including
    frying, which is one of the most popular cuisine preparations. The stove height and work envelope
    are two major ergonomic issues in performing cooking task. There has been little research focusing
    on Malaysian elderly task performing in addressing these issues. The objectives of this study were to
    identify the acceptable stove height and depth and to determine the working envelope among Malaysian
    elderly using anthropometric data. A total of 55 Malaysian elderly (25 male and 30 female) aged between
    60 to 85 years participated in this study. Five body measurements were taken from each subject using
    an anthropometer. The measurements are stature height, shoulder height, arm span, arm reach forward
    and waist height. Apart from these anthropometric measurements, their present stove height was also
    measured. The acquisition of stove height dimensions was performed through a series of door to door
    visit of the elderly homes in Kg. Sg. Merab. These variables were used to estimate the elderly working
    envelope and determine the stove height, width and depth. Data were analysed using SPSS software. The
    waist height dimension was to estimate the stove height, the arm reach forward for the depth and the arm
    span for the length of the table-top where the stove was placed. Meanwhile the stature and shoulder height
    were used for estimating the position of the overhead compartment or placement of cooking utensils.
    The 5
    th
    percentile was chosen since it is appropriate to accommodate 90% of the studied population. The 5
    th
    percentile was also applied for the setting
    of the working envelope so as to provide better
    reaching tolerances. Meanwhile, standard was used
    to compare the present state of the studied kitchen
    setting. The results show that 56.4% of the elderly
    waist height is lower than the standard table-top
    height which is 36 inches (91.4cm) and 36.4% of the stove height was found higher than that of the standard. This could apparently cause fatigue and
    discomfort to shoulders, the neck, the arm and the back of the user. Anthropometrics measurements can
    be used for estimating the stove height, length and depth. These could also calculate a space taken for
    certain physical activities, such as frying task envelope. Providing a good combination of stove height,
    length, depth and ergonomic working envelope could hopefully improve the elderly cooking task and
    increase their quality of life.

    In order to investigate the role of roasting conditions in antioxidant formation, methanol and hot water extracts from Robusta coffee beans roasted for various lengths of time and at various temperatures were analyzed for total phenolic acid, chlorogenic acid, and caffeine content, as well as for their antioxidant activities using 1,1-diphenyl-2-picryhydrazyl (DPPH), thiobarbituric acid (TBA), and malonaldehyde/gas chromatography (MA/GC) assays. The amount of total phenolics in methanol extracts decreased linearly over the roasting temperature from 63.51 ± 0.77 mg chlorogenic acid equivalent (CAE)/g coffee beans (roasted at 200°C) to 42.56 ± 0.33 mg CAE/g coffee beans (roasted at 240°C). The total chlorogenic acid content decreased when the roasting time was increased from 78.33 ± 1.41 mg/g (green coffee beans) to 4.31 ± 0.23 mg/g (roasted for 16 min at 250°C). All methanol extracts from roasted coffee beans possessed over 90% antioxidant activities in the DPPH assay. The antioxidant activity of methanol extracts ranged from 41.38 ± 1.77% (roasted at 250°C for 10 min) to 98.20 ± 1.49% (roasted at 230°C for 16 min) as tested by the TBA assay. The antioxidant activity of methanol extracts of green coffee beans and roasted coffee beans ranged from 93.01% (green coffee beans) to 98.62 ± 1.32% (roasted at 250°C for 14 min) in the MA/GC assays. All hot water extracts exhibited moderate pro-oxidant activities in TBA and MA/GC assays. The results indicated that roasting conditions of coffee beans play an important role in the formation of antioxidants in brewed coffee, which can be dietary supplements having beneficial effect to human health.

    Extensive use of synthetic-based polymer plastic as packaging medium to pack food products has led to serious environmental problems due to their total non-biodegradability property. The stability of nutritional composition and physical traits of chicken patties containing oyster mushroom packed with biodegradable and non-degradable packaging materials were studied. The chicken patties containing oyster mushroom were packed with either biodegradable plastic (BP), paper box (PB) or non-biodegradable high density polyethylene (HDPE). Generally, there were no significant (P>0.05) different in all nutrient analyzed except for carbohydrate after 6 months of storage for chicken patties packed with different types of packaging. The chicken burger packed with both BP and PB packagings were able to retain the moisture and fat without jeopardizing the diameter reduction and cooking yield during storage. There were no differences in all nutrient analyzed after 6 months of storage of chicken patties packed with either biodegradable packagings (BP and PB) or non-degradable packaging. In addition, frozen storage does not significantly affect the concentration of of β-glucan in both BP and PB packagings. In summary, these results indicate that biodegradable packagings applied in packing chicken patty frozen for 6 months were effective in controlling the microbial growth and provide wholesomeness and safety to the chicken patty containing oyster mushroom.
