    Marination directly affects the texture and flavor of meat and is important for product yield. This research investigated the effects of various marinating solutions on the physicochemical, microstructural and sensory properties of golek chicken, a popular dish in Malaysia, Indonesia and southern Thailand. Non-marinated meat (Tr1-control) was compared with five marinating treatments: distilled water (Tr2); sodium chloride (Tr3); a mixture of sodium chloride and sodium tripolyphosphate (STPP) (Tr4); a mixture of sodium chloride, STPP and citric acid (Tr5); and a mixture of sodium chloride, STPP and sodium bicarbonate (Tr6). Marinating meat in Tr3–Tr6 resulted in higher water-holding capacity and cooking yield, as well as lower shear force value and cooking loss, when compared to Tr1 and Tr2 (p

    In the present study, Malaysian Zea mays hair extracts are screened for the occurrence of bioactive compounds. The results positively showed the present of flavonoids, saponin, tannins, phlobatannins, phenols, alkaloids and cardiac glycosides in both aqueous and methanolic extract of Zea mays hair. Terpenoid compounds however present only in the methanolic extract sample. In addition, the total phenolic content (TPC) in aqueous extract was significantly higher (42.71 + 0.87 µg/g of tannic acid equivalent (TAE)) compared to methanolic extract (40.38 + 1.10 µg/g of TAE). The findings suggested that phytochemicals present in Zea mays hair are potentially beneficial as therapeutic and antioxidative agents in pharmaceuticals, food and other related industries.

    The present work sought to investigate the nutritional composition and phytochemical properties of red pitaya (Hylocereus polyrhizus) juices from Malaysia and Australia and to determine the optimum ethanol concentration (in the range of 0 – 100% ethanol) for the extraction of phenolic, flavonoid and betacyanin contents. The predominant macronutrient in red pitaya juice was carbohydrate while potassium and vitamin A were the major mineral and vitamin content. Red pitaya juice from Malaysia achieved optimal total phenolic content at 20% of ethanol (20 mL ethanol in 100 mL water, v/v); total flavonoid content at 60% (v/v); and betacyanin content at 0% (v/v). Red pitaya juice from Australia achieved the maximum total phenolic content at 60% (v/v); total flavonoid content at 20% (v/v); and betacyanin content at 80% (v/v). Nutritional composition and the phytochemical properties of red pitaya in Malaysia and Australia were significantly different suggested the role of environmental factors like soil and climate on the phytochemical properties of red pitaya.

    Habiba U, Afifi AM, Salleh A, Ang BC
    J Hazard Mater, 2017 Jan 15;322(Pt A):182-194.
    PMID: 27436300 DOI: 10.1016/j.jhazmat.2016.06.028
    In this study, chitosan/polyvinyl alcohol (PVA)/zeolite nanofibrous composite membrane was fabricated via electrospinning. First, crude chitosan was hydrolyzed with NaOH for 24h. Afterward, hydrolyzed chitosan solution was blended with aqueous PVA solution in different weight ratios. Morphological analysis of chitosan/PVA electrospun nanofiber showed a defect-free nanofiber material with 50:50 weight ratio of chitosan/PVA. Subsequently, 1wt.% of zeolite was added to this blended solution of 50:50 chitosan/PVA. The resulting nanofiber was characterized with field emission scanning electron microscopy, X-Ray diffraction, Fourier transform infrared spectroscopy, swelling test, and adsorption test. Fine, bead-free nanofiber with homogeneous nanofiber was electrospun. The resulting membrane was stable in distilled water, acidic, and basic media in 20 days. Moreover, the adsorption ability of nanofibrous membrane was studied over Cr (VI), Fe (III), and Ni (II) ions using Langmuir isotherm. Kinetic parameters were estimated using the Lagergren first-order, pseudo-second-order, and intraparticle diffusion kinetic models. Kinetic study showed that adsorption rate was high. However, the resulting nanofiber membrane showed less adsorption capacity at high concentration. The adsorption capacity of nanofiber was unaltered after five recycling runs, which indicated the reusability of chitosan/PVA/zeolite nanofibrous membrane. Therefore, chitosan/PVA/zeolite nanofiber can be a useful material for water treatment at moderate concentration of heavy metals.

    Malaysia is the world’s top manufacturer of examination and surgical natural rubber (NR) gloves, exported mainly to the USA and Europe. The glove manufacturing process yields effluent which must be treated to comply with the stringent regulatory requirements imposed by the Malaysian Department of Environment. To make glove manufacturing an eco-friendly process, efforts are geared towards minimizing and utilizing waste or converting it into raw material for making value-added products. Waste generated from the glove industry is mainly rubber sludge which is obtained from the chemical flocculation stage of the effluent treatment process and consists of mainly rubber, remnants of compounding ingredients and water. R&D work by the Malaysian Rubber Board on waste utilization and resource recovery investigations have revealed many uses for this sludge. This paper briefly outlines only one of the many options available, which is the conversion of the sludge into sludge derived fuel (SDF). Preliminary study has identified three formulations of SDF with calorific values (CV) exceeding 16 000 kJ/kg, matching a good grade coal. This was considered as promising results which warrant explorative work for further increasing the CV of SDF to turn it into a viable fuel substitute in the latex products manufacturing industry and subsequently apply for a Clean Development Mechanism status to generate income.

    Outbreak management in disaster has to be planned and implemented prior to, during and after the disaster is over. The risk of outbreaks following disaster is related to the size, health status and living conditions of the displaced population. The risk is increased due standing water in floods for vector borne diseases, overcrowding, inadequate water and sanitation and poor access to health care. The 2006-2007 flood in Johore resulted in 2 episodes of food poisoning and an outbreak of coxsackie A24 acute haemorrhagic conjunctivitis. Only 19,667 (12.5%) of the 157,018 displaced persons suffered from communicable diseases which comprised of acute respiratory disease 7361(28%), skin infection 4241(19%), acute gastroenteritis 1872(8%) and conjunctivitis 589 (2%). The routine disease surveillance and environmental control were enhanced to cover the relief centers and flood areas. Risk assessment of communicable disease carried out resulted in prompt control measures and good coverage of preventive activities. In conclusion the Johore State Health Department has successfully manage the outbreaks during the major flood.

    International Food Research Journal, 2011;18(4):1523-1530.
    MyJurnal
    A total of 49 isolates of V. parahaemolyticus and 8 isolates of V. cholerae isolated from freshwater fish of patin (Pangasius hypopthalmus) and red tilapia (Oreochromis sp.) were purchased from different retail level in Selangor, Malaysia. All of the isolates showed a multiple resistances towards all 15 antibiotics tested. Some of the isolates show a high resistance to different antibiotics including bacitracin, vancomycin, tetracycline, furazididone, cephalothin and erythromycin. However, both species was susceptible towards imipenem. Overall antibiotics resistance patterns of all isolates were resistant from 2 to 14 resistance patterns with multiple antibiotic resistance (MAR) index ranging from 0.13 to 0.93 respectively. As the results obtained in the dendrogram produced from both species had indicates that these antibiotics were intensively used whether in the aquaculture farm through feeds during culture or at the hatchery production of seed. Thus, this study will provides an essential information of the MAR index and also the clustering analysis in order to determine the biosafety of Vibrio spp. in freshwater aquaculture fish sold at different retail level in Malaysia.

    Vibrio parahaemolyticus is a foodborne pathogen and their human infection is regularly associated with the consumption of raw or undercooked seafood and contaminated water supplies. Many conventional biochemical identification and confirmation procedures are performed to detect the presence of this pathogen, both from seafood or environmental samples. However, these procedures not only require two or more days to complete, they do not have the capabilities to determine the number of V. parahaemolyticus cells in any given samples. Thus, in this study we describe the development of a rapid SYBR green based real-time PCR assay, targeting the thermo labile (tl) gene of V. parahaemolyticus for the detection and enumeration of this bacterium from seafood and environmental samples. We report that the real-time PCR assay and the primers designed are highly specific, and only generated the desired amplicons with V. parahaemolyticus DNA samples against other bacteria and fungi species. Our assay is also highly sensitive, and, is able to detect V. parahaemolyticus with high coefficient values in concentrations as low as 1.0 pg/μl DNA for pure genomic DNA solutions and 10 cells/ml in serially diluted cell suspension and spiked samples. This assay can be completed in less than 3 hours and may be used as a tool for rapid determination of V. parahaemolyticus densities in the food industries, environmental risk assessment and for clinical diagnostics purposes.

    The study examined the protein profile of Pectoralis major muscle in broiler chickens subjected to different freezing and thawing methods. Pectoralis major muscle was excised from the carcasses of twenty broiler chickens and split into left and right halves. The left half was subjected to slow freezing (-20oC) while the right half was rapidly frozen (-80oC). The samples were stored at their respective temperature for 2 weeks and assigned to either of tap water (27oC, 30 min), room temperature (26oC, 60 min), microwave (750W, 10 min) or chiller (4oC, 6 h) thawing. Changes in myofibrillar proteins following the thawing methods were monitored through sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). The electrophoretic profile indicated differences (p < 0.05) in intensities of the components of myofibrillar proteins among the thawing methods in both slow and rapidly frozen samples. Chiller thawing had significantly higher (p < 0.05) protein concentration than other methods in rapidly frozen samples. However, in slow freezing, there were no significant differences in protein concentration among the thawing methods. In rapidly frozen samples, the protein optical densities at molecular weight of 21, 27, 55 and 151kDa in tap water, chiller and room temperature thawing did not differ (p < 0.05). Similarly, in slowly frozen samples, protein optical densities at molecular weight of 21, 27, 85 and 151 kDa were not significantly different among chill, tap water and room temperature thawing. Microwave thawing consistently caused higher protein degradation resulting in significantly lower (p < 0.05) protein quality and quantity in both freezing methods.

    Microbiological quality analysis of freshwater prawns from three sampling sites in Peninsular Malaysia viz: Site 1- Kg. Jumbang, Negri Sembilan; Site 2- Kg. Cangkat Tin, Perak and Site 3- Kg. Cenderiang, Perak for total mesophilic and psychrophilic aerobic counts, proteolytic bacterial counts, histamine producing bacteria, cadaverine producing bacteria and putrescine producing bacteria in the prawns and pond water for the three sites showed that the microbiological quality of freshwater prawns is related to the microflora of pond water in which they were grown. The initial bacterial counts indicated the values were in the range of log 4+ CFU/g for all samples. Total mesophilic and psychrophilic counts of the head regions were higher than that of the body regions for all prawn samples and types of growth media tested. All samples showed an increase in counts with time and temperature of storage up to log 7+ CFU/g for mesophilic counts after 12 hours at ambient, 6 days at 10 ± 2°C and 12 days at iced storage. The samples from Site 2 had relatively higher counts compared to the other two sites which correlated well with the levels determined in the pond water. Similar trends were observed for psychrophilic counts but at lower values for the different types of media studied.
    Effects of preservatives on quality changes and shelf life of shrimp during iced storage indicated that boric acid, lactic acid and sodium metabisulphite managed to inhibit psychrophilic bacteria and biogenic amines formation in prawns while maintaining the mesophilic counts at lower levels during iced storage.

    MyJurnal
    The addition of ribose to minced chicken or minced pork followed by heating at 95oC yielded minced
    meat with different pH, colour (CIE L*, b*) and absorbance values that can be used as indicators for species differentiation. The higher intensity of the Maillard reaction parameters in minced chicken was due to the higher protein and lysine contents, and the presence of more water-soluble proteins within the minced chicken during heating. Cluster analysis using Maillard reaction parameters showed that the two types of minced meat could be classified into two different groups. A confidence interval (95% confidence) analysis revealed that the absorbance, CIE L* values, and CIE b* values could be used as indicators for differentiation between the two types of minced meat, as the intervals between these Maillard reaction parameters for the two minced meats were far apart.

  14. Fulltext Contribution of Arab countries to pharmaceutical wastewater literature: a bibliometric and comparative analysis of research output
    Zyoud SH, Zyoud SH, Al-Jabi SW, Sweileh WM, Awang R
    Ann Occup Environ Med, 2016;28:28.
    PMID: 27382475 DOI: 10.1186/s40557-016-0117-0
    BACKGROUND: Recently, the pharmaceutical manufacturing industry has been growing rapidly in many countries in the world, including in Arab countries. Pharmaceuticals reach aquatic environments and are prevalent at small concentrations in wastewater from the drug manufacturing industry and hospitals. Such presence also occurs in domestic wastewater and results from the disposal of unused and expired medicines. Therefore, the objective of this study was to analyze and compare the quantity and quality of publications made by researchers in Arab countries on pharmaceutical wastewater.

    METHODS: To retrieve documents related to pharmaceutical wastewater, we used the Scopus database on November 21, 2015. All documents with terms related to pharmaceutical wastewater in the title or abstract were analysed. Results obtained from Arab countries were compared with those obtained from Turkey, Iran and Israel.

    RESULTS: Globally, a total of 6360 publications were retrieved while those from Arab countries, Iran, Turkey and Israel, were 179, 113, 96 and 54 publications respectively. The highest share of publications belonged to Kingdom of Saudi Arabia (KSA) with a total of 47 (26.2 %) publications, followed by Egypt (38; 21.2 %), Tunisia (17; 9.5 %) and Morocco (16; 8.9 %). The total number of citations was 1635, with a mean of 9.13 and a median (inter quartile range) of 3 (1.0-10.0). The study identified 87 (48.6 %) documents with 32 countries of international collaboration with Arab countries. It was noted that Arab researchers collaborated mainly with authors in Western Europe (54; 30.2 %), followed by authors from the Asiatic region (29; 16.2 %) and Northern America (15; 8.4 %). The most productive institution was King Saud University, KSA (13; 7.3 %), followed by the National Research Centre, Egypt (10; 7.3 %).

    CONCLUSIONS: This study showed that KSA has the largest share of productivity on pharmaceutical wastewater research. Bibliometric analysis demonstrated that research productivity, mainly from Arab countries in pharmaceutical wastewater research, was relatively lagging behind. More research effort is required for Arab countries to catch up with those of non-Arab Middle Easter countries on pharmaceutical wastewater research.

    Plants, particularly fruits and vegetables, have many phytochemicals that possess various bioactivities, including antioxidant and anticancer properties. In this study, the aim was to investigate the antiproliferative properties of Syzygium fruits, namely water apple (Syzygium aqueum), milk apple (Syzygium malaccense), and malay apple (Syzygium malaccense L.) against two types of cancer-origin cells, namely MCF-7 (hormone dependent breast cancer cell line) and MDA-MB-231 (nonhormone-dependent breast cancer cell line). Two solvent methods were prepared using aqueous and methanol extraction. Antiproliferation activities of these extracts were evaluated by employing colorimetric MTT (3-(4,5-dimethylthiazol-2-yl)2,5 diphenyltetrazolium bromide) assay through time periods of 24, 48, and 72 hours. The result showed that extracts from the three fruits had no significant effects for 24 and 48 hours time periods (p >0.05) but extracts of Water apple and Malay apple displayed antiproliferation effects on MCF-7 cell lines (p

    The spray-dried Vernonia amygdalina water extract was evaluated for antidiabetic effect using normoglycaemic, glucose induced hyperglycaemic and streptozotocin induced diabetic mice. This effect was compared with an oral dose of Momordica charantia. Besides, acute toxicity of the extract was also evaluated at concentration 2000 and 5000 mg/kg body weight. The extract was able to reduce blood glucose level in glucose and streptozotocin induced hyperglycaemic mice without causing hypoglycemic effect on fasting normoglycaemic mice. Moreover, mice appeared to be normal and no mortality was observed in the acute toxicity study after treated with up to 5000mg/kg of extract. These results indicated that the spray-dried Vernonia amygdalina water extract was a potential antidiabetic agent which does not induce hypoglycemic and acute toxicity on normal subject.

    The peels of pomelo contribute 30% of the fruit weight and yet it has been dump without recognizing the possible nutritional value of the peels. Study has been carried out to identify flavonoid content of the peels and analysed the activity of the flavonoid towards inhibition of lipid peroxidation. Optimization of flavonoid extraction was conducted using aqueous solvent (methanol and ethanol), extraction time (1-3 h) and extraction temperature (50°C-80°) via water bath extraction. The total content of flavonoids was quantitatively determined by using coloration methods with chromogenic system of NaNO2–Al (NO3)3–NaOH and and it was found that the extraction at 65ºC for 2 h in aqueous ethanol was the optimized condition for maximum flavonoids i.e. 190.42mg/L. A spectrophometric analysis was performed to evaluate flavonoid activity towards lipid peroxidation in the fish tissue. There was reduction in Peroxide value (PV) indicated the inhibition of lipid peroxidation in fish treated with pomelo peel as evidence of concurrency of positive flavonoid activity.

    There is an increase need and demand to update Malaysian Food Composition Database (FCD) which was last updated in 1997. The current FCD program was designed to expand the quantity and improve the quality of the existing database. The present work was aimed to determine the nutrient content of commercial rice products from three rice varieties classified as raw and processed foods, namely Basmati, Siam, and Fragrant rice. A total of six brands from each type of rice were sampled from a local supermarket within Klang Valley. Analyses were carried out for 27 nutrients that include proximate (Energy, Water, Protein, Fat, Carbohydrate, Total Dietary Fibre, and Ash), minerals (Magnesium, Calcium, Sodium, Iron, Zinc, and Copper), water soluble vitamins (C, B1, B2, B3, B6 and B9), fat soluble vitamins (A and E), total sugar, fatty acids (total saturated fat, total monounsaturated fat and total polyunsaturated), trans fatty acids, and cholesterol. The three rice varieties were found to contain comparable nutrient levels except for vitamin C, B1, A, E and total sugar which were not detected in all samples. The fatty acid (total saturated, total monounsaturated, and total polyunsaturated) as well as trans- fatty acid were detected at very low levels. Cholesterol was not detected in all samples. These findings can be utilised in raising public awareness and assistance to better estimate nutrient contents and intake depending on the varieties of rice.

    MyJurnal
    Although Malaysia is one of the important pineapple fruit producing and exporting country, the production of MD-2 pineapple fruit only started in 2009. Pineapple fruit has been harvested at different ripening stages for different markets. The information on Malaysian grown MD-2 pineapple fruit quality is lacking. Therefore this work was carried out with the aim to determine physicochemical quality, antioxidant compounds and activity of MD-2 pineapple fruit at five ripening stages. Ripening stage affected physicochemical quality of MD-2 pineapple fruit. Soluble solids concentration of MD-2 pineapple fruit increased from 15.41 to 18.02% SSC when fruit ripened from stage 1 to 4 and no significant difference was found in fruit between stage 4 and 5. The ascorbic acid content decreased while total carotenoids content increased as ripening stage advanced. The total phenolic content of both 80% methanol and water extraction solvents increased significantly as fruit ripened from stage 1 to 3 and reduced as fruit ripened to stage 5. The antioxidant activity of MD-2 pineapple fruit as assayed using DPPH, FRAP and ABTS showed similar trend as total phenolic content. These results suggest that ripening stage affect MD-2 pineapple fruit quality and nutritional values.

    The objective of this study was to determine the physicochemical properties of pink guava (Psidium guajava) puree and its anti-hypertensive effect on Spontaneous Hypertensive Rats (SHR). Antioxidant activities of pink guava puree in water and ethanol extracts, based on 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, were 1.43±0.04 mg/gfm and 0.28±0.01 mg/gfm, respectively. A total of 24 male SHRs were divided into a control group, CG, and 3 treatment dosage groups [low dose group, LDG (0.5 g/kg body weight/day), medium dose group, MDG (1.0 g/kg body weight/day), and high dose group, HDG (2.0 g/kg body weight/day)]. Final body weights for treatment dosage groups were lower [MDG (313.01±31.25 g), HDG (318.56±17.96 g), LDG (320.01±22.70 g)] compared to CG (331.08±41.29 g). Final systolic blood pressure values from the beginning and the end of the experiment in MDG and HDG were 231-179 mmHg and 246-169mm Hg, respectively. These results were significantly lower when compared with CG (241-223 mmHg) from the beginning until the end of the experiment. As a conclusion, these results showed that pink guava puree has anti-hypertensive properties.
