    Stable isotope analysis has been used extensively to establish trophic relationships in many ecosystems. Present study utilised stable isotope signatures of carbon and nitrogen to identify trophic structure of aquatic food web in river and rice field ecosystems in Perak, northern peninsular Malaysia. The mean δ(13)C values of all producers ranged from -35.29 ± 0.21 to -26.00 ± 0.050‰. The greatest δ(15)N values noted was in zenarchopterid fish with 9.68 ± 0.020‰. The δ(15)N values of aquatic insects ranged between 2.59 ± 0.107 in Elmidae (Coleoptera) and 8.11 ± 0.022‰ in Nepidae (Hemiptera). Correspondingly, with all the δ(13)C and δ(15)N values recorded, it can be deduced that there are four trophic levels existed in the freshwater ecosystems which started with the producer (plants), followed by primary consumer (aquatic insects and non-predatory fish), secondary consumer (invertebrate predators) and lastly tertiary consumer (vertebrate predators).

    Chitin, being the second most abundant biopolymer after cellulose, has been gaining popularity since its initial discovery by Braconot in 1811. However, fundamental knowledge and literature on chitin and its derivatives from insects are difficult to obtain. The most common and sought-after sources of chitin are shellfish (especially crustaceans) and other aquatic invertebrates. The amount of shellfish available is obviously restricted by the amount of food waste that is allowed; hence, it is a limited resource. Therefore, insects are the best choices since, out of 1.3 million species in the world, 900,000 are insects, making them the most abundant species in the world. In this review, a total of 82 samples from shellfish-crustaceans and mollusks (n = 46), insects (n = 23), and others (n = 13)-have been collected and studied for their chemical extraction of chitin and its derivatives. The aim of this paper is to review the extraction method of chitin and chitosan for a comparison of the optimal demineralization and deproteinization processes, with a consideration of insects as alternative sources of chitin. The methods employed in this review are based on comprehensive bibliographic research. Based on previous data, the chitin and chitosan contents of insects in past studies favorably compare and compete with those of commercial chitin and chitosan-for example, 45% in Bombyx eri, 36.6% in Periostracum cicadae (cicada sloughs), and 26.2% in Chyrysomya megacephala. Therefore, according to the data reported by previous researchers, demonstrating comparable yield values to those of crustacean chitin and the great interest in insects as alternative sources, efforts towards comprehensive knowledge in this field are relevant.

    Heavy metal pollution in an aquatic environment has become of the main concern to the world due to their non-biodegradable properties, toxicity, persistence, and their ability to adsorb into food chains. With rapid industrialization and development nowadays, heavy metals are introduced continuously into the estuaries and coastal region through rivers, runoff, and land-based point sources. These heavy metals may degrade the aquatic environment and harm the living organisms and toward human indirection through secondary contact. The dataset provided is to give an overview of the spatial and temporal distribution of the heavy metals concentration in Merang River surficial sediment collected from September 2017 to July 2018, subsequently every two months dataset. Sediment samples were collected in 44 stations along the river and 20 stations in the coastal area, which total up to 64 stations. Teflon Bomb closed digestion method with mixed acid was used to digest the sediments. The concentration of heavy metals in the sediment were analysed by using Inductively Coupled Plasma Mass Spectrometer (ICP-MS). The spatial distribution of heavy metals shows the effect of monsoon and wet and dry seasons in the sampling area. Thus, this dataset reveals six months of information on natural and anthropogenic sources intrusion at the Merang River and may also help in monitoring the pollution in the area.

    The objective of this study was to determine the level of preservatives and microbiological loads in various brands of commercially available chili bo (paste). Fifteen different brands of chili bo obtained from the local market and hypermarkets were analyzed for pH, moisture and benzoic acid content, microbiological loads (aerobic, anaerobic, aerobic spores, and fungi), and thermophilic microorganisms. Results showed that both moisture content and pH vary among samples. The concentrations of benzoic acid detected in chili bo were found to be in the range of 537 to 5,435 mg/kg. Nine of fifteen brands were found to exceed the maximum level permitted by the Malaysian Food Law in accordance with the Codex Alimentarius (1,000 mg/kg for benzoic acid). An apparent correlation between benzoic acid concentration and microbiological loads present in the chili bo was observed. The microbiological loads were found to be relatively low in the end products containing high amounts of benzoic acid. The heat-resistant (70 to 80 degrees C) microorganisms present in chili bo were identified as Ochrobacterum tritici, Stenotrophomonas rhizophila, Microbacterium maritypicum, Roseomonas spp., CDC group II-E subgroup A, Flavimonas oryzihabitans, and Pseudomonas aeruginosa, with M. maritypicum being the most frequently found (in 9 of 15 samples) microorganism. Most of these identified microorganisms were not known to cause foodborne illnesses.

    The genomics and genetic data of pigmented and non-pigmented Malaysian rice varieties are still limited. Hence, we performed the genome resequencing of two black rice varieties (Bali, Pulut Hitam 9), two red rice varieties (MRM16, MRQ100) and two white rice varieties (MR297 and MRQ76) using Illumina HiSeq 4000 platform with 30x sequencing coverage. We aimed to identify and annotate single nucleotide polymorphisms (SNPs) from the genome of these four pigmented and two non-pigmented rice varieties. The potential SNPs will be used in developing the functional SNP markers related to nutritional (i.e. antioxidant, folate, amylose) and quality (i.e. aromatic) traits. Raw data of the pigmented and non-pigmented rice varieties have been deposited into the European Nucleotide Archive (ENA) database with accession number PRJEB29070 and PRJEB32344, respectively.

    Food variety scores (FVS) and dietary diversity scores (DDS) were estimated based on foods consumed weekly by 285 Malaysian households using a food frequency questionnaire. The scoring system of FVS and DDS was based on a scale of 0-7 and 0-6 respectively. The mean household FVS and DDS was 164.1 ± 93 and 6 ± 0.4. The age of respondents (husbands or wives; p < .01), sex (p < .05), and household food expenditure (p < .01) had a significant influence on both FVS and DDS. The food-intake pattern of Malaysian households showed that their typical diets had high protein and energy-based foods.

    OBJECTIVE: To explore the perspectives, barriers and enablers on salt reduction in out-of-home sectors in Malaysia among street food vendors, caterers and consumers.

    DESIGN: A qualitative study involving twenty-two focus group discussions and six in-depth interviews was conducted, recorded and transcribed verbatim. An inductive thematic analysis approach was employed to analyse the data.

    SETTING: Two in-depth interviews and twenty-two focus group discussions were conducted face-to-face. Four in-depth interviews were conducted online.

    PARTICIPANTS: Focus group discussions were conducted among twenty-three street food vendors, twenty-one caterers and seventy-six consumers of various eateries. In-depth interviews were conducted among two street food vendors and four caterers, individually.

    RESULTS: Consumers and food operators perceived a high-salt intake within Malaysia's out-of-home food sectors. Food operators emphasised the necessity for a comprehensive salt reduction policy in the out-of-home sector involving all stakeholders. Consumers faced limited awareness and knowledge, counterproductive practices among food operators and challenges in accessing affordable low-Na food products, whereas food operators faced the lack of standardised guidelines and effective enforcement mechanisms and uncooperative consumer practices. Both groups expressed that food quality and price of salt were also the barriers, and they advocated for awareness promotion, enhanced regulation of manufactured food products and stricter enforcement targeting vendors. Consumers also suggested promoting and recognising health-conscious food premises, whereas food operators suggested on knowledge enhancement tailored to them, strategies for gaining consumers acceptance and maintaining food quality.

    CONCLUSIONS: These findings provide valuable insights that serve as foundational evidence for developing and implementing salt reduction policies within Malaysia's out-of-home sectors.

    Diseases spread through food still remain a common and persistent problems resulting in appreciable morbidity and occasional mortality. Food handlers play an important role in ensuring food safety throughout the chain of production, processing, storage and preparation. This study is to explore the pattern of sociodemographic distribution and to determine knowledge, attitude and practice of food handlers towards food-borne diseases and food safety. A total of 430 food handlers were randomly selected from Kota Bharu district and interviewed by using structured questionnaire. Distribution of food handlers was Malays (98.8%), females (69.5%), married (81.4%), working in food stalls (64.2%), involved in operational areas (49.3%), having no license (54.2%) and immunized with Ty2 (60.7%). The mean age was 41 +/- 12 years and the mean income was RM 465 +/- 243/month. The educational level was found as no formal education (10.5%), primary school (31.9%), secondary school (57.0%) and diploma/degree holders (0.7%). A significant number of food handlers (57.2%) had no certificate in food handlers training program and 61.9% had undergone routine medical examinations (RME). Almost half (48.4%) had poor knowledge. Multiple logistic regression showed type of premise [Odd ratio (OR) = 4.0, 95% Confidence interval (CI) =1.8-7.5, p = 0.0004], educational level (OR = 4.0, 95% CI = 1.8-7.4, p = 0.0003) and job status of food handlers (OR = 0.5, 95% CI = 0.3-0.8, p = 0.0031) significantly influenced the level score of knowledge. No significant difference of attitude and practice between trained and untrained food handlers. Findings of this preliminary study may help in planning health education intervention programs for food handlers in order to have improvement in knowledge, attitude and practice towards food-borne diseases and food safety. Furthermore, it will in turn reduce national morbidity and mortality of food-borne diseases.

    The purpose of this study was to evaluate the effect of different cooking methods on the allergenicity of cockle and to identify proteins most frequently bound by IgE antibodies using a proteomics approach. Raw, boiled, fried and roasted extracts of the cockle were prepared. The protein profiles of the extracts were obtained by separation using sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) and 2-dimensional gel electrophoresis (2-DE). IgE-immunoblotting was then performed with the use of individual sera from patients with cockle allergy and the major IgE-binding proteins were analyzed by mass-spectrometry. SDS-PAGE of raw extract showed 13 protein bands. Smaller numbers of protein bands were detected in the boiled, fried and roasted extracts. The 2-DE gel profile of the raw extract further separated the protein bands to ~50 protein spots with molecular masses between 13 to 180 kDa and isoelectric point (pI) values ranging from 3 to 10. Immunoblotting of raw extract exhibited 11 IgE-binding proteins with two proteins of 36 and 40 kDa as the major IgE-binding proteins, while the boiled extract revealed 3 IgE-binding proteins. Fried and roasted extracts only showed a single IgE-binding protein at 36 kDa. 2-DE immunoblotting of raw extract demonstrated 5 to 20 IgE reactive spots. Mass spectrometry analysis led to identification of 2 important allergens, tropomyosin (36 kDa) and arginine kinase (40 kDa). Heated extracts showed a reduction in the number of IgE-reactive bands compared with raw extract, which suggest that thermal treatment can be used as a tool in attempting to reduce cockle allergenicity. The degree of allergenicity of cockle was demonstrated in the order raw > boiled > fried ≈ roasted. Two important allergens reacting with more than 50% of patients' sera identified using mass spectrometric approaches were tropomyosin and arginine kinase. Thus, allergens found in this study would help in component based diagnosis, management of cockle allergic patients and to the standardisation of allergenic test products as tools in molecular allergology.

    Background: A cross sectional study was carried out to determine the prevalence of microbiological contamination in ready- to-eat food and factors affecting it in Melaka from February 2008 till May 2008 in collaboration with the Food Safety and Quality Unit and District Health Offices in Melaka Tengah, Alor Gajah and Jasin.

    Methods: A purposive sampling of 101 food premises was carried out and 202 ready- to-eat food samples were collected and analysed microbiologically using standard methods. A total of 202 food handlers were randomly selected for questionnaire interview while rectal and nasal swabs were taken from them to determine their healthy carrier status of pathogenic food bacteria.

    Results: Results showed that the overall prevalence of microbiological contamination in ready- to-eat food was 35.1%, while prevalence by type of food was 42.0% for main dishes and 9.8% for staple food. The majority of the contaminations were due to coliforms (14.9%), total plate counts (12.4%) and Staphylococcus aureus (3.5%). The mean score for food premise inspection was 77.21 ± 10.32 and the prevalence of healthy carrier status of pathogenic food bacteria among the food handlers was 15.8%. The level of food handling practices among food handlers was influenced by sex (p=0.012) and formal training on food handling courses (p=0.009). There was a significant negative correlation between age and level of food handling practices among the food handlers (r = -0.163; p = 0.02).

    Gelatin and collagen are considered halal-critical ingredients as they are typically derived from either bovine or porcine animals. Current analytical methods for determining the sources of gelatin and collagen suffer from limitations in terms of robustness and false positives in peptide matching. Thus, the aim of this study was to investigate the utility of monitoring hydroxyproline, a signature amino acid for gelatin and collagen, for identifying potentially haram foodstuffs. To determine the hydroxyproline profiles among animal- and plant-based samples, one-way univariate analysis of variance followed by pair-wise comparison was used to establish statistical significance. Multivariate chemometric analysis through principal component analysis revealed a discrete distribution pattern among 59 samples due to hydroxyproline variability. Finally, inter- and intra-laboratory comparisons demonstrated the validity and robustness of hydroxyproline determination according to ISO 17025. Thus, this preliminary identification technique will aid the identification of potentially haram foodstuffs.

    This study was carried out to determine the blood glucose response and glycaemic index (GI) values of four types of commercially available breads in Malaysia. Twelve healthy volunteers (six men, six women; body mass index, 21.9±1.6 kg/m(2); age, 22.9±1.7 years) participated in this study. The breads tested were multi-grains bread (M-Grains), wholemeal bread (WM), wholemeal bread with oatmeal (WM-Oat) and white bread (WB). The subjects were studied on seven different occasions (four tests for the tested breads and three repeated tests of the reference food) after an overnight fast. Capillary blood samples were taken immediately before (0 min) and 15, 30, 45, 60, 90 and 120 min after consumption of the test foods. The blood glucose response was obtained by calculating the incremental area under the curve. The GI values were determined according to the standardized methodology. Our results showed that the M-Grains and WM-Oat could be categorized as intermediate GI while the WM and WB breads were high GI foods, respectively. The GI of M-Grains (56±6.2) and WM-Oat (67±6.9) were significantly lower than the reference food (glucose; GI = 100) (P < 0.05). No significant difference in GI value was seen between the reference food and the GI of WM (85±5.9) and WB (82±6.5) (P > 0.05). Among the tested breads, the GI values of M-Grains and WM-Oat were significantly lower (P < 0.05) than those of WM and WB. There was no relationship between the dietary fibre content of the bread with the incremental area under the curve (r = 0.15, P = 0.15) or their GI values (r = 0.17, P = 0.12), indicating that the GI value of the test breads were unaffected by the fibre content of the breads. The result of this study will provide useful nutritional information for dieticians and the public alike who may prefer low-GI over high-GI foods.

    BACKGROUND: Changes in dietary practices are known to be associated with changes in the health and disease pattern of a population. This study aimed to qualitatively explore the perception of colorectal cancer patients regarding causes of colorectal cancer and the influence of diet.

    MATERIALS AND METHODS: Twelve respondents from three major ethnicities in Malaysia were selected from the quantitative study on dietary pattern and colorectal cancer carried out earlier in this study. In-depth interviews (IDI), conducted from April until June 2012, were mainly in the Malay language with additional use of English and continued until the saturation point was reached. All interviews were autorecorded so that verbatim transcriptions could be created.

    RESULTS: Causes of colorectal cancer were categorized into internal and external factors. The majority of respondents agreed that there is an association between Western foods and colorectal cancer. Malaysian traditional diet was not related to colorectal cancer as less preservative agents were used. Malaysian diet preparation consisting of taste of cooking (spicy, salty and sour foods) plus type of cooking (fry, grilled and smoked) were considered causes of colorectal cancer. All respondents changed their dietary pattern to healthy food after being diagnosed with colorectal cancer. Advice from doctors regarding suitable food for colorectal cancer was useful in this regard.

    CONCLUSIONS: Eating outside, use of food flavoring ingredients and preservative agents were considered to be the main factors causing colorectal cancer. All respondents admitted that they changed to a healthy diet after being diagnosed with colorectal cancer.

    BACKGROUND: Complementary foods with breastfeeding are foods or drinks given to children aged 6-23 months to meet their nutritional needs. The non-optimal provision of complementary feeding influences malnutrition in children of this age.

    AIMS: To analyze the factors associated with complementary feeding practices among children aged 6-23 months in Indonesia.

    METHODS: A cross-sectional design was employed using data from the 2017 Indonesia Demographic and Health Survey. A total of 502,800 mothers with children aged 6-23 months were recruited through multistage cluster sampling. Data were analyzed using a logistic regression test to determine the correlation between predisposing, enabling, and reinforcing factors and complementary feeding practices.

    RESULTS: A prevalence values of analysis showed that approximately 71.14%, 53.95%, and 28.13% of the children met MMF, MMD, and MAD, respectively. The probability of achieving minimum dietary diversity (MDD) was high in the following: children aged 18-23 months (odds ratio [OR] = 9.58; 95% confidence interval [CI] = 7.29-12.58), children of mothers with higher education (OR = 5.95; 95% CI = 2.17-16.34), children from households with upper wealth index (OR = 2.53; 95% CI = 1.85-3.48), children of mothers who received childbirth assistance by professionals (OR = 1.63; 95% CI = 1.20-2.20), and children of mothers who had access to the Internet (OR = 1.26; 95% CI = 1.06-1.50). Moreover, children from households with the upper wealth index (OR = 1.40; 95% CI = 1.03-1.91), children whose mothers were employed (OR = 1.19; 95% CI = 1.02-1.39) living in urban areas (OR = 1.28; 95% CI = 1.06-1.54) and children of mothers who received childbirth assistance by professionals (OR = 1.33; 95% CI = 0.98-1.82) were more likely to meet Minimum Meal Frequency (MMF). Finally, children aged 18-23 months (OR = 2.40; 95% CI = 1.81-3.17), of mothers with higher education (OR = 3.15; 95% CI = 0.94-10.60), from households with upper wealth index (OR = 1.41; 95% CI = 1.05-2.90) and born with professional childbirth assistance (OR = 1.82; 95% CI = 1.21-2.75) were significantly associated with minimum acceptable diet (MAD).

    CONCLUSIONS: The findings revealed that the prevalence of MDD and MAD in Indonesia was low. Strategies such as improving health services, economic conditions, and education level of mothers are needed to improve infant and young child feeding in Indonesia.

    The 3-Monochloropropane-1, 2-diol ester (3-MCPDE) and glycidyl ester (GE) are formed at high processing temperatures with the presence of respective precursors. Both are potentially harmful to humans, causing adverse health impacts including kidney damage, reproductive problems, and increased risk of cancer. The presence of 3-MCPDE and GE in palm oil is of particular concern because of its widespread use by the food industry. There are a variety of methods for reducing 3-MCPDE and GE. For example, water washing eliminates mostly inorganic chlorides that, in turn, reduce the formation of 3-MCPDE. 3-MCPDE has also been reduced by up to 99% using combinations of methods and replacing stripping steam with alcohol-based media. Activated carbon, clay, antioxidants, potassium-based salts, and other post-refining steps have positively lowered GE, ranging from 10 to 99%. Several approaches have been successful in reducing these process contaminants without affecting other quality metrics.

    The rising concern about the presence of 3-monochloropropane 1,2 diol ester (3-MCPDE) and glycidyl ester (GE) in food has prompted much research to be conducted. Some process modifications and the use of specific chemicals have been employed to mitigate both 3-MCPDE and GE. Alkalisation using NaOH, KOH, alkali metals or alkaline earth metals and post sparging with steam or ethanol and short path distillation have shown simultaneous mitigation of 51-91% in 3-MCPDE and of 13-99% in GE, both contaminants achieved below 1000 µg/kg. Some of the mitigation methods have resulted in undesirable deterioration in other parameters of the refined oil. When the processed oil is used in food processing, it results in changes to 3-MCPDE and GE. Repeated deep frying above 170 °C in the presence of NaCl and baking at 200 °C with flavouring (dried garlic and onion), resulted in increased 3-MCPDE. Repeated frying in the presence of antioxidants (TBHQ, rosemary and phenolics) decreased 3-MCPDE in processed food. The GE content in foods tends to decline with time, indicating instability of GE's epoxide ring.

    In this data article we present the determinations of the diet preference and growth of a pair of the giant panda, Ailuropoda melanoleuca (David, 1869) from Zoo Negara Malaysia. Once considered as endangered, the captive giant pandas were given with nine species of local bamboo in separate indoor enclosures. We recorded data between May 25, 2014 and December 31, 2016 and analysed it based on food preference, the pattern toward food consumption and body weights using SPSS v25.0 (IBM, USA). Data on the bamboo preference, daily average bamboo provided and consumed, and factors predicting of body weight per individual are reported in this article. The data highlight correlation between panda growth (kg) to the part of bamboo consumed (kg) and exhibit the pattern of preferred part of food (i.e.: either the leaf, culm or shoots of bamboo variety) for panda consumptions.

    We conducted 2 case-control studies with Malaysian and Hong Kong Chinese and investigated the association between salted fish intake and nasopharyngeal carcinoma (NPC). Both studies show a highly significant association between salted fish intake, especially during childhood, and NPC. Furthermore, from our results we estimate that the majority of NPC cases occurring in the southern Chinese can be attributed to their consumption of this food early in life.
