Ahmad NA, Yook Heng L, Salam F, Mat Zaid MH, Abu Hanifah S

Sensors (Basel), 2019 Nov 05;19(21).
PMID: 31694284 DOI: 10.3390/s19214813

A developed colorimetric pH sensor film based on edible materials for real-time monitoring of food freshness is described. The mixed natural dyes from edible plants Clitoria sp and Brassica sp were extracted and incorporated into ι-carrageenan film as a colorimetric pH sensor film for monitoring food spoilage and its freshness. The color changes of the developed colorimetric sensor film were measured with chromametry and UV-vis spectroscopy, respectively. Experimental results show that colorimetric pH sensor film demonstrated statistically significant differences (p < 0.05) between CIE-L*a*b* coordinates color system indicated that the developed colorimetric sensor film was able to give a gradual change in color over a wide pH range. The color of the colorimetric sensor film also changes discretely and linearly with factors that contribute to food spoilage using shrimp and durian samples. Moreover, the developed colorimetric pH sensor film has the potential to be used as a safe, non-destructive testing and also a flexibly visual method for direct assessment of food freshness indicator during storage.

Afsah-Hejri L, Jinap S, Hajeb P, Radu S, Shakibazadeh S

Compr Rev Food Sci Food Saf, 2013 Nov;12(6):629-651.
PMID: 33412719 DOI: 10.1111/1541-4337.12029

Fungi are distributed worldwide and can be found in various foods and feedstuffs from almost every part of the world. Mycotoxins are secondary metabolites produced by some fungal species and may impose food safety risks to human health. Among all mycotoxins, aflatoxins (AFs), ochratoxin A (OTA), trichothecenes, deoxynivalenol (DON and T-2 toxin), zearalenone (ZEN), and fumonisins (FMN) have received much attention due to high frequency and severe health effects in humans and animals. Malaysia has heavy rainfall throughout the year, high temperatures (28 to 31 °C), and high relative humidity (70% to 80% during wet seasons). Stored crops under such conditions can easily be contaminated by mycotoxin-producing fungi. The most important mycotoxins in Malaysian foods are AFs, OTA, DON, ZEN, and FMN that can be found in peanuts, cereal grains, cocoa beans, and spices. AFs have been reported to occur in several cereal grains, feeds, nuts, and nut products consumed in Malaysia. Spices, oilseeds, milk, eggs, and herbal medicines have been reported to be contaminated with AFs (lower than the Malaysian acceptable level of 35 ng/g for total AFs). OTA, a possible human carcinogen, was reported in cereal grains, nuts, and spices in Malaysian market. ZEN was detected in Malaysian rice, oat, barley, maize meal, and wheat at different levels. DON contamination, although at low levels, was reported in rice, maize, barley, oat, wheat, and wheat-based products in Malaysia. FMN was reported in feed and some cereal grains consumed in Malaysia. Since some food commodities are more susceptible than others to fungal growth and mycotoxin contamination, more stringent prevention and control methods are required.

Tang RH, Yang H, Choi JR, Gong Y, Feng SS, Pingguan-Murphy B, et al.

Crit Rev Biotechnol, 2016 Apr 14.
PMID: 27075621 DOI: 10.3109/07388551.2016.1164664

In recent years, paper-based point-of-care testing (POCT) has been widely used in medical diagnostics, food safety and environmental monitoring. However, a high-cost, time-consuming and equipment-dependent sample pretreatment technique is generally required for raw sample processing, which are impractical for low-resource and disease-endemic areas. Therefore, there is an escalating demand for a cost-effective, simple and portable pretreatment technique, to be coupled with the commonly used paper-based assay (e.g. lateral flow assay) in POCT. In this review, we focus on the importance of using paper as a platform for sample pretreatment. We firstly discuss the beneficial use of paper for sample pretreatment, including sample collection and storage, separation, extraction, and concentration. We highlight the working principle and fabrication of each sample pretreatment device, the existing challenges and the future perspectives for developing paper-based sample pretreatment technique.

Sufficient knowledge on food safety and diligence during food handling are crucial to food safety and hygiene practices. A casual approach to handling food in the kitchen on a regular basis may link to foodborne pathogens, contaminations, and adverse health effects. The purpose of this study is to identify the right practices and behaviour among culinary students in terms of food hygiene practices and food safety perspectives. The methodology employed includes observations on 18 food culinary students in an actual kitchen setting. Effective food hygiene and food safety implementation are needed to improve the effectiveness of health education programmes for food handlers. The results suggest that transmission reduction of food pathogens, knowledge transfer and food safety training in selective industry criteria with proper guidelines should be introduced to produce a competent workforce.

Chik Z, Haron DE, Ahmad ED, Taha H, Mustafa AM

Food Addit Contam Part A Chem Anal Control Expo Risk Assess, 2011;28(7):967-73.
PMID: 21607892 DOI: 10.1080/19440049.2011.576401

Migration of melamine has been determined for 41 types of retail melamine-ware products in Malaysia. This study was initiated by the Ministry of Health, Malaysia, in the midst of public anxiety on the possibility of melamine leaching into foods that come into contact with the melamine-ware. Thus, the objective of this study was to investigate the level of melamine migration in melamine utensils available on the market. Samples of melamine tableware, including cups and plates, forks and spoons, tumblers, bowls, etc., were collected from various retail outlets. Following the test guidelines for melamine migration set by the European Committee for Standardisation (CEN 2004) with some modifications, the samples were exposed to two types of food simulants (3% acetic acid and distilled water) at three test conditions (25°C (room temperature), 70 and 100°C) for 30 min. Melamine analysis was carried out using LC-MS/MS with a HILIC column and mobile phase consisting of ammonium acetate/formic acid (0.05%) in water and ammonium acetate/formic acid (0.05%) in acetonitrile (95 : 5, v/v). The limit of quantification (LOQ) was 5 ng/ml. Melamine migration was detected from all samples. For the articles tested with distilled water, melamine migration were [median (interquartile range)] 22.2 (32.6), 49.3 (50.9), 84.9 (89.9) ng/ml at room temperature (25°C), 70 and 100°C, respectively. In 3% acetic acid, melamine migration was 31.5 (35.7), 81.5 (76.2), 122.0 (126.7) ng/ml at room temperature (25°C), 70 and 100°C, respectively. This study suggests that excessive heat and acidity may directly affect melamine migration from melamine-ware products. However the results showed that melamine migration in the tested items were well below the specific migration limit (SML) of 30 mg/kg (30,000 ng/ml) set out in European Commission Directive 2002/72/EC.

Piper cubeba L. is traditionally recognised as flavouring ingredient in various types of foods and has been used to marinate meat. Scientifically, it has been reported to possess various valuable nutritional and pharmacological properties including antimicrobial potential. The aim of the present work was to determine the antibacterial activity of ethanolic P. cubeba L. extract against Escherichia coli and its effect on the microbiological quality of raw chicken meat during storage. Disc diffusion assay was done and resulted in 8.40 ± 0.10 mm of inhibition zone. The bacteriostatic and bactericidal effects of the extract were determined at 0.63 ± 0.00 mg/mL and 1.25 ± 0.00 mg/mL of concentration by MIC and MBC methods, respectively. The killing time was recorded at 2 × MIC (1.25 mg/mL) for 4 h. The application of the extract on chicken meat samples showed reduction in TPC and E. coli count with the observed optimum condition at 5.00% concentration stored at -18°C for 14 days based on the consistent reduction. Sensory attributes acceptability evaluation by 9-point hedonic scale showed acceptable score for colour, odour, texture and overall acceptability of the treated raw chicken meat samples. The findings implies that P. cubeba L. can be listed as one of the alternatives to reduce the bacterial load of raw chicken meat prior to cooking which is very important in ensuring food safety as well as reducing the occurrence of foodborne poisoning associated with chicken meat.

Noordiana N., Fatimah A.B., Mun, A.S.

International Food Research Journal, 2013;20(1):117-124.
MyJurnal

Lactic acid bacteria (LAB) are non-pathogenic bacteria that have an important role in human daily life. LAB produce antimicrobial agents, such as bacteriocins, diacetyl and hydrogen peroxide which help to extend the shelf life of food products. In this study, LAB were isolated from selected seafood; threadfin salmon and grass shrimp. Antibacterial activity of LAB extracts against Salmonella typhimurium, Listeria monocytogenes, Bacillus cereus and Escherichia coli were determined using the disc diffusion method. Three strains of LAB were selected for the characterization of antibacterial agents produced by LAB. The parameters such as pH, heat, incubation period and medium, were analyzed in this experiment. Changes in environmental parameters affected the activity of antibacterial agents. The antibacterial agents produced by LAB were generally heat stable and stable in a wide range of pH levels. However, the inhibition activity of LAB was destroyed with a heat treatment of 121°C, and the antibacterial effect was reduced at a pH of 12, which occurs in most strains. The medium containing NaCl enhanced the
antibacterial activity of P1S1 and P3S3 strains against S. typhimurium, L. monocytogenes and E. coli. Moreover, the antibacterial agents exhibited the greatest inhibition activity at incubation times between 24 and 72 h. The antibacterial activity was reduced after an incubation time of 96 h. The characterization of antibacterial agents aids in the improvement of food products safety

Zakuan, Z., Mustapa, S.A., Sukor, R., Rukayadi, Y.

International Food Research Journal, 2018;25(1):433-438.
MyJurnal

The filamentous spoilage fungi in vegetables can lead to significant impact in food and economic loss. In order to overcome this problem, chemical fungicide has been implemented in vegetable farming and processing but it causes problems towards environment and food safety. Thus, the utilization of natural products such as plants extracts, which exhibit antimicrobial and antifungal activity, is more acceptable to solve this problem. The aim of this study is to investigate the antifungal activity of Boesenbergia rotunda extract against ten filamentous spoilage fungi isolated from five vegetables. The extract was used to treat fungal isolates from vegetables; CRb 002 (Penicillium sp.), CHa 009 (Aspergillus sp.), TMa 001 (Geotrichum sp.), TMa 002 (Aspergillus sp), ONb 001 (Aspergillus sp.), WBb 003 and WBb 004 (Fusarium sp.) WBb 007 (unidentified), WBb 008 (Aureobasidium sp.) and WBb 010 (Penicillium sp.). The results showed that the yield of the extract of B. rotunda using ethanol (95%) was 11.42% (w/v). The 10% of B. rotunda extract exhibited antifungal activities against ten filamentous fungi after 5 days treatment with growth reduction of 41.56%, 30.68%, 86.20%, 50.62%, 26.67%, 47.44%, 50.74%, 36.39%, 42.86%, and 39.39% for WBb 008, WBb 004, WBb 007, WBb 003, CRb 002, WBb 010, CHa 009, TMa 001, ONb 001, and TMa 002, respectively. B. rotunda extract showed highest antifungal activity against fungi isolated from winged bean (WBb 007) with percentage reduction in growth was 86.20%, while the lowest activity was against fungi isolated from the carrot (CRb 002) with 26.67% reduction in growth. Generally, the TPC of fungi in the vegetable samples were reduced after treatment with 5% of B. rotunda extract at 5 min and 10 min of exposure time. The results suggested that B. rotunda extract has high potential to become natural food preservative which can reduce the fungi spoilage of vegetables.

Halimatunsadiah, A.B., Norida, M., Omar, D., Kamarulzaman, N.H.

International Food Research Journal, 2016;23(5):85-94.
MyJurnal

This study investigates pest management practices among lowland farmers on growing
leafy and fruit vegetables, particularly focusing on the pesticide usage in controlling pest. In
Malaysia, vegetable productions in lowland areas are to some extent really important as in the
highland areas due to the wide marketing channel, from local till traded across border. Yet, the
ignorance of vegetables safety regarding the appropriate of pesticide usage by farmers was
undeniable, as the market demands only products with good extrinsic quality. Thus a survey
was conducted among of 85 of lowland vegetable farmers to get information on their pest
management practices in farms. Result showed that the pesticide application by farmers on
vegetables crops still indicated a calendar spraying practices. In most cases, farmers tend to
harvest the vegetable products shortly after a few days of last pesticide spraying. In order to
enhance the food safety control starting from the primary production, extensive monitoring of
the current pesticide usage by farmers in vegetable productions is vital to provide an updated
data on the food safety risk regarding to the pesticide residues. Therefore, the thrust of this
paper was to get a better understanding on the level of safe pesticide usage among vegetables
farmers especially in areas of growing vegetables productions.

PMID: 31137897 DOI: 10.3390/molecules24102025

The agricultural industry has made a tremendous contribution to the foundations of civilization. Basic essentials such as food, beverages, clothes and domestic materials are enriched by the agricultural industry. However, the traditional method in agriculture cultivation is labor-intensive and inadequate to meet the accelerating nature of human demands. This scenario raises the need to explore state-of-the-art crop cultivation and harvesting technologies. In this regard, optics and photonics technologies have proven to be effective solutions. This paper aims to present a comprehensive review of three photonic techniques, namely imaging, spectroscopy and spectral imaging, in a comparative manner for agriculture applications. Essentially, the spectral imaging technique is a robust solution which combines the benefits of both imaging and spectroscopy but faces the risk of underutilization. This review also comprehends the practicality of all three techniques by presenting existing examples in agricultural applications. Furthermore, the potential of these techniques is reviewed and critiqued by looking into agricultural activities involving palm oil, rubber, and agro-food crops. All the possible issues and challenges in implementing the photonic techniques in agriculture are given prominence with a few selective recommendations. The highlighted insights in this review will hopefully lead to an increased effort in the development of photonics applications for the future agricultural industry.

PMID: 37487946 DOI: 10.1016/j.tmaid.2023.102620

BACKGROUND: Annually, 600 million individuals are affected by food-borne diseases (FBD), alongside 425,000 fatalities. Improving the general public knowledge of, attitudes towards, and practices in, (KAP) food safety is necessary for minimizing FBD transmission. In Malaysia, migrant workers account for 11.1% of the workforce, with a high proportion involved in food and beverage services. Therefore, this study aimed (i) to evaluate the current food safety KAP, and (ii) to identify the strategies to promote food safety awareness, among migrant workers across occupational sectors in Klang Valley.
METHOD: A survey was conducted with 403 migrant workers through phone interviews and online self-administered questionnaires. Piecewise structural equation modelling and multinomial regression were applied to identify predictor variables for food safety KAP and to explore differences across nationalities.
RESULTS: The respondents were Nepalese, Filipino and Indonesian. The majority were male, working in the services industry, had completed high school, aged between 30 and 39 years and had worked in Malaysia for less than ten years. Knowledge was significantly correlated with attitudes and practices. Female respondents had lower knowledge and attitude scores while younger respondents had lower knowledge scores. Indonesian and Filipino respondents had lower knowledge and attitudes scores than Nepalese respondents. Understanding food safety information from social media was positively correlated with the respondents' food safety knowledge and practices.
CONCLUSION: These findings highlighted: (i) the need to target female, younger, Indonesian and Filipino migrant workers, and (ii) the potential of social media to improve public awareness of food safety and hygienic practices.

Genes (Basel), 2018 Aug 12;9(8).
PMID: 30103564 DOI: 10.3390/genes9080408

The present study demonstrated High Resolution Melting (HRM) analysis combined with DNA barcode (Bar-HRM) as a fast and highly sensitive technique for detecting adulterants in Eurycoma longifolia commercial herbal products. Targeting the DNA barcoding of the chloroplastic region-ribulose biphosphate carboxylase large chain (rbcL) and the nuclear ribosomal region- internal transcribed spacer 2 (ITS2), PCR amplification and HRM analysis using saturated Eva green dye as the source of fluorescence signals, was accomplished by employing a real-time cycler. The results were further validated by sequencing to identify unknown sequence from Genbank database and to generate phylogenetic tree using neighbour joint (NJ) analysis. Both of the DNA markers exhibited a distinguishable melting temperature and shape of the normalised curve between the reference and the adulterants. In the case of species identification, ITS2 was more successful in differentiating between species. Additionally, detection of admixture sample containing small traces of targeted E. longifolia DNA (w/v) can be detected as low as 5% for rbcL and less than 1% for ITS2, proving the sensitivity and versatility of the HRM analysis. In conclusion, the Bar-HRM analysis is a fast and reliable technique that can effectively detect adulterants in herbal products. Therefore, this will be beneficial for regulatory agencies in order to regulate food safety issues.

J Food Prot, 2020 Mar 01;83(3):452-459.
PMID: 32065648 DOI: 10.4315/0362-028X.JFP-19-415

ABSTRACT: Social media offers numerous advantages for personal users and organizations to communicate, socialize, and market their products. When used correctly, social media is an effective tool to communicate and to share food safety news and good practices. However, there have been reports of fake food safety news shared via social media, fueling panic and resulting in a loss of revenue. Thus, this study aimed to investigate the consumers' awareness, trust, and usage of social media in communicating food safety news in Malaysia. A questionnaire divided into five sections-(i) demographics, (ii) reaction to food safety news, (iii) consumers' awareness, (iv) social media truth and level of trust, and (v) social media uses and content creation-was created and shared online. A total of 341 questionnaires were returned of which 339 surveys were valid. This study revealed that less than one-third of the study group (27.1%) knew which of the food safety news were fake. Most respondents (67.8%) were less likely to purchase the affected foods if the foods were featured in social media as problematic, although no differences were made between true and fake news and how that would influence respondents' willingness to purchase affected foods. Overall, 62% of the respondents agreed or strongly agreed about the usage of social media and its ability to prevent food poisoning cases, while more than 50% of the respondents were in total agreement that social media allow consumers to act more responsibly by sharing food safety news. Respondents tended to trust information shared by scientists (67.5%) and family members and friends (33%). Respondents would most often share the news after verifying its authenticity (46%). If respondents experienced a personal food safety issue (e.g., discovered a fly in their meal), they seldom or never took photos to post online (56.1%). It is possible that the respondents preferred to inform the food handlers and/or shop owners about the affected products rather than post the photos online. It is suggested that targeted food safety information and media literacy be provided to improve consumers' awareness and to positively influence self-verification of the food safety information before sharing. This study provides crucial insights for a range of stakeholders, particularly public authorities, food bloggers, and the public, in using social media effectively to build consumers' awareness and trust in food safety information.

The growth of the Malaysian’s per capita income has generally empowered consumers to have more choices for food, more purchasing power, health consciousness and demand for more nutritional values of their food intake. Motivated by the changes in Malaysian consumer’s food choice, a conjoint analysis was performed to investigate Malaysian consumers’ demand for rice attributes and how much consumers are willing to pay for the demanded attribute. A conjoint analysis is a method used in identifying and understanding the combined effects of product attributes on preferences for a product or service. In conjoint analysis, utility is the conceptual basis for assessing the value of a product or service, where individuals make decisions between bundles of products based on their budget constraints. The findings suggested that the most important attribute for rice was food safety, followed by taste and size of grain. Consumers were also willing to pay premium prices for the demanded attributes. The findings would have positive implications for the agrifood industry if it responds effectively to translate into business opportunities to these changes.

As Malaysian economies grow, Malaysian per capita income is likely to increase. From economics point of view, it is expected that better-off consumers will move to better quality of food attributes such as freshness, food safety, quality and healthfulness in their food intake. This study aimed to investigate the demand for eggs attributes by Malaysian consumers. The study considers the conjoint analysis technique as a method for acquiring insights into preferences for eggs product. The technique was applied to establish the trade-offs that Malaysian consumers make between size, colour, size of packaging, functional attribute and price in the purchasing of eggs for 202 respondents. Least squares regression was utilized to estimate the relative importance of attributes for eggs. The results revealed that the ideal characteristic of egg was one with large size (grade A), omega eggs, brown, and ten per packs. We also found that consumers were also willing to pay more for their preferred attributes. The results found in the study provide valuable inputs to producers or marketers to improve their marketing efforts as well as market positioning, in line with the demanded eggs attributes.
