Fulltext Embedding Islamic dietary law into an HACCP approach for application to the poultry slaughtering and processing industry

Kohilavani, Zzaman, W., Abdullah, W.W.N., Tajul, A.Y.

International Food Research Journal, 2015;22(6):2684-2690.
MyJurnal

Since early 2000, Malaysian food-export industries have recognised the demand for food
compliant with Islamic dietary law (halal), with primary consumer choices based on quality
and safety. The lack of documented monitoring for health hazards and haram substances led
to the withdrawal of certification. The HACCP-based halal quality-assurance standards were
developed as a result, using the HACCP criteria for safety, religious dietary requirement and
quality. Halal critical control points (HlCCP) are identified using HACCP criteria and a question
tree on HALAL processing and storage. This approach harmonizes and unifies halal processing
with the specific food industry via an HACCP–based halal quality-assurance system.

Khan, M.R.T., Chamhuri, S., Farah, H.S.

International Food Research Journal, 2015;22(1):131-138.
MyJurnal

The term ‘sustainable’ has become a buzz word in today’s business world. Consumption of green food is just one facet or ‘trip’ to the whole journey of sustainable development. This paper explores and synthesizes the findings of research on green food consumption in Malaysia. The already conducted studies in Malaysia have revealed various demographic and psychographic factors contributing to consumers’ intension to buy green food. This study revealed that majority of Malaysians consider food safety and health issue to be their prime reason for buying green food. To ensure the long term sustainability, the green food as well as the broad food industry in Malaysia must evidently understand the consumers’ buying motives of green food. Although mentionable limitation of the paper is the reliance on only published literature, this can be used as input for further large scale empirical research. The paper concludes with implications and suggestions for further research.

Fulltext Research progress in Bioflocculants from bacteria

Abdullah, A.M., Hamidah, H., Alam, M.Z.

International Food Research Journal, 2017;24(101):0-0.
MyJurnal

Although one of the major users of flocculants are water and wastewater treatment industries, flocculants are also used in various food industries. The chemical flocculants are preferred widely in these industries due to low production cost and fast production ability. However, the negative effects of the chemical flocculants should not be neglected to gain the economic benefits only. Therefore, the researchers are working to discover efficient and economical flocculants from biological sources. Several attempts have been made and are still being made to extract or produce bioflocculants from natural sources such as plants, bacteria, fungi, yeast, algae, etc. The review revealed that significant amount of work have been done in the past, in search of bioflocculant. However, commercially viable bioflocculants are yet to be marketed widely. With the advent of new biotechnologies and advances in genetic engineering, the researchers are hopeful to discover or develop commercially viable, safe and environmentfriendly bioflocculants.

Bacteriophages are ubiquitous in our world, mainly in the oceans, soil, the water and food
we consume. They can be used efficiently in modern biotechnology, as well as alternatives
to antibiotics for many antibiotic resistant bacterial strains. Phages can be used as vehicles
for vaccines both DNA and protein, for the detection of pathogenic bacterial strain, as biocontrol
agents in agriculture and food industry. This review outlines the properties as well
as the influence of different external physical and chemical factors like temperature and
acidity on phage persistence. A better understanding of the complex problem of phage
sensitivity to external factors may be useful for other researchers working with phages.
Furthermore, the applications of bacteriophages were described in this paper as well.

Fulltext The effectiveness of food handler training programmes in Malaysia and Ireland to prevent food-borne disease

Tirmizi, L.I.T., Brand, H., Son, R., New, C.Y.

Food Research, 2018;2(3):247-257.
MyJurnal

According to the World Health Organisation (WHO), globally 600 million people suffer
from food-borne diseases (FBD), and 420,000 people die as a result. The European Food
Safety Authority (EFSA) has stated that FBD are linked to the food industry, with the
most common means of transmission being due to poor food handling and hygiene by
food handlers working in the food industry. The aim of this research was to investigate the
effectiveness of mandatory food handler training programmes (FHTP) to prevent FBD in
Malaysia and Ireland. To do this, the FHTP existing in Malaysia and Ireland were
analysed, in addition to the legislation they fall under in each respective country.
Effectiveness was determined by investigating the level of food safety knowledge (FSK)
and food safety practices (FSP) of food handlers in Malaysia and Ireland. A systematic
literature review (SLR) and a narrative literature review (NLR) were conducted for this
research. The SLR was based on the PRISMA diagram, using the Confidence in the
Evidence from Reviews of Qualitative research (CERQual) approach to evaluate the
studies used for this research. A total of 8 Malaysian studies and 1 Irish study were used to
determine the level of FSK and FSP of food handlers in each respective country, to
examine the effectiveness of FHTP. The results of the studies used for this research have
depicted overall good FSP and FSK of food handlers in Malaysia and Ireland; yet trends
continue to show that food handlers are one of the biggest contributors to FBD,
demonstrating that FHTP are not effective in preventing FBD. The findings from this
research highlights that although these trainings can be an effective tool to prevent FBD, if
they are not executed correctly, food handlers will continue to contribute to FBD.

Amiza, M.A., Kong, Y.L., Faazaz, A.L.

International Food Research Journal, 2012;19(1):199-206.
MyJurnal

The effect of degree of hydrolysis (DH) on the physicochemical properties of cobia frame hydrolysate was determined. Three levels of degree of hydrolysis of cobia frame hydrolysate were studied, which were 53%, 71% and 96%. After enzymatic hydrolysis using Alcalase®, the samples were spray-dried. Cobia hydrolysate powder samples were analyzed for their proximate analysis and physicochemical properties. The proximate analysis showed significant differences in fat and ash content only. DH96 hydrolysate showed desirable essential amino acid profile for human requirement except for methionine and isoleucine. The study found that cobia frame hydrolysate had good colour, emulsifying capacity and excellent foaming properties. However, there were no significant differences in water-holding capacity, oil-holding capacity and peptide solubility among the hydrolysate samples. This study suggested that cobia frame hydrolysate is a potential ingredient and foaming agent for food industry.

Listeria monocytogenes (L. monocytogenes) is a serious food-borne pathogen for immunocompromised individuals. L. monocytogenes is capable of producing biofilm on the surface of food processing lines and instruments. The biofilm transfers contamination to food products and impose risk to public health. Transfers contamination to food products, and impose risk hazard to public health. The aim of this study was to investigate biofilm producing ability of L. monocytogenes isolates. Microtitre assay was used to measure the amount of biofilm production by ten L. monocytogenes isolates from minced chicken / meat, sausages and burgers. Results showed that all 10 L. monocytogenes isolates were able to form biofilm after 24 h at 20˚C on polystyrene surface (the common surface in food industries). Some strains were capable of forming biofilm more than the others. All strains showed a slight raise in the quantities of attached cells over 48 and 72 h. L. monocytogenes strains isolated from minced chicken, minced meat and burgers were better biofilm-producers comparing to the strains isolated from sausages.

PMID: 38165964 DOI: 10.1371/journal.pone.0295771

INTRODUCTION: The significant contribution of the food and beverage industry to Malaysia's Gross Domestic Product is projected to increase in the upcoming years. With the industry's expansion, the demand for workers on food premises would also continuously increase. The food industry workers are exposed to risks arising from physical, chemical, biological, ergonomic, and psychosocial hazards while performing their duties. Thus, it is essential for these workers to be equipped with proper knowledge, attitude, and practices (KAP) in safety and health.
AIMS: This study aims to develop and evaluate the effectiveness of the safety and health programme TRIMOSH (Theory-Based Intervention Module on Occupational Safety and Health) in improving the knowledge, attitude, and practice among food industry workers.
METHODS: TRIMOSH intervention study is a two-arm randomised, single-blinded, controlled, parallel trial that will be conducted among food industry workers in Selangor, Malaysia. In a partnership with Food Handler Training Schools in Selangor, 10 pairs of Food Handler Training Schools with 12 participants per group (n = 240) will be recruited for balanced randomisation intervention and control conditions. Furthermore, data collection of all participants was conducted at four time points: baseline (T0), immediately (T1), one month (T2), and three months (T3) post-intervention. Generalised Linear Mixed Model (GLMM) will be conducted to determine the effects of intervention within and between study groups. Subsequently, the primary outcomes increase the knowledge, attitude, and practice (KAP) of safety and health at food premises. Clinical Trial Registry registration was approved by the ClinicalTrials.gov committee on October 2022 with the ClinicalTrials.gov Identifier: NCT05571995. This study has also been approved by the Ethics Committee for Research Involving Human Subjects of Universiti Putra Malaysia (JKEUPM-2022-346). All participants are required to provide consent prior to participation.
CONCLUSIONS: The characteristics of the respondents are expected to show no difference between the groups. It is hypothesised that TRIMOSH is effective in improving the knowledge, attitude, and practices of food industry workers in Selangor. The results will be reported and presented in international peer-reviewed journals, conferences, and other platforms. In addition, the TRIMOSH programme will be offered at the national level by the relevant authorities for the benefit of food industry workers.

Fulltext Optimal designs of the median run length based double sampling X chart for minimizing the average sample size

Teoh WL, Khoo MB, Teh SY

PLoS One, 2013;8(7):e68580.
PMID: 23935873 DOI: 10.1371/journal.pone.0068580

Designs of the double sampling (DS) X chart are traditionally based on the average run length (ARL) criterion. However, the shape of the run length distribution changes with the process mean shifts, ranging from highly skewed when the process is in-control to almost symmetric when the mean shift is large. Therefore, we show that the ARL is a complicated performance measure and that the median run length (MRL) is a more meaningful measure to depend on. This is because the MRL provides an intuitive and a fair representation of the central tendency, especially for the rightly skewed run length distribution. Since the DS X chart can effectively reduce the sample size without reducing the statistical efficiency, this paper proposes two optimal designs of the MRL-based DS X chart, for minimizing (i) the in-control average sample size (ASS) and (ii) both the in-control and out-of-control ASSs. Comparisons with the optimal MRL-based EWMA X and Shewhart X charts demonstrate the superiority of the proposed optimal MRL-based DS X chart, as the latter requires a smaller sample size on the average while maintaining the same detection speed as the two former charts. An example involving the added potassium sorbate in a yoghurt manufacturing process is used to illustrate the effectiveness of the proposed MRL-based DS X chart in reducing the sample size needed.

Developments in understanding and applying prebiotics in research and practice-an ISAPP conference paper

Scott KP, Grimaldi R, Cunningham M, Sarbini SR, Wijeyesekera A, Tang MLK, et al.

J Appl Microbiol, 2020 Apr;128(4):934-949.
PMID: 31446668 DOI: 10.1111/jam.14424

AIMS: The concept of using specific dietary components to selectively modulate the gut microbiota to confer a health benefit, defined as prebiotics, originated in 1995. In 2018, a group of scientists met at the International Scientific Association for Probiotics and Prebiotics annual meeting in Singapore to discuss advances in the prebiotic field, focussing on issues affecting functionality, research methodology and geographical differences.
METHODS AND RESULTS: The discussion ranged from examining scientific literature supporting the efficacy of established prebiotics, to the prospects for establishing health benefits associated with novel compounds, isolated from different sources.
CONCLUSIONS: While many promising candidate prebiotics from across the globe have been highlighted in preliminary research, there are a limited number with both demonstrated mechanism of action and defined health benefits as required to meet the prebiotic definition. Prebiotics are part of a food industry with increasing market sales, yet there are great disparities in regulations in different countries. Identification and commercialization of new prebiotics with unique health benefits means that regulation must improve and remain up-to-date so as not to risk stifling research with potential health benefits for humans and other animals.
SIGNIFICANCE AND IMPACT OF STUDY: This summary of the workshop discussions indicates potential avenues for expanding the range of prebiotic substrates, delivery methods to enhance health benefits for the end consumer and guidance to better elucidate their activities in human studies.

Recent research suggesting the existence of potential source of pectin from roselle calyces. Pectin was successfully extracted from seven different varieties of roselle calyces. Pectin extraction was conducted using hydrochloric acid (HCl, 0.03 N, pH 1.5) or ammonium oxalate (0.25% w/v, pH 4.6) at 85⁰C for 1 h. Chemical characteristics of the HCl- and ammonium oxalate extracted pectin were compared. Results indicated that ammonium oxalate exhibited greater efficiency in pectin extraction than HCl. Highest pectin yield at 18.7% was obtained by ammonium oxalate extraction of roselle calyx variety Acc.6 compared to only 9.77% by HCl extraction. The lowest pectin yield at 11.3% and 5.78% were observed respectively in ammonium oxalate and HCl extractions of roselle calyx variety UKMR-3. Some important characteristics of ammonium oxalate extracted pectin of roselle Acc.6 were 5.98% moisture, 3.81% ash, 4.64% methoxyl content, 42.24% anhydrouronic acid (AUA) and degree of esterification (DE) 60%. This study suggested that the high DE% roselle pectin is an alternative source of pectin for food industry.

MyJurnal

Chhana jalebi is a popular product in middle and northern parts of India and is prepared by frying of batter made from chhana, maida and water and finally soaking in sugar syrup. This chhana based fried sweet product is being prepared and sold by halwais in Indian sweet market. It has a coiled structure with syrupy interiors and chewy body. It has close resemblance to maida jalebi and khoa jalebi, but has firmer coils. The manufacturing procedure varies widely from manufacturer to manufacturer. There was no proper (standard) manufacturing method available for the preparation of chhana jalebi. Hence, a study was conducted to standardize a method for its manufacture consequently it will be helpful to produce the jalebi on a commercial scale. The chhana jalebi was standardized by various process parameters such as fat level in milk 3%, ratio of maida - chhana combination 1:1, water level in batter 45%, frying time and temperature 160-170°C, sugar syrup concentration 68°Brix and soaking time 2 min. Standardized product was analyzed by various physical, chemical, microbial, sensory and textural characteristics. The product had a light brown coloured coiled appearance, crispy body and texture. The nutritional composition percentage of chhana jalebi was protein 5.71±0.20, carbohydrate 67.11±0.19, fat 12.53±0.17 and moisture 20.23±0.25. The shelf life of the jalebi was found to be 5 days at 28°C. This was enhanced to 18 days by using potassium sorbate as preservative at the permitted levels. The optimized process and enhanced shelf life will pave way for commercialization and mechanization of chhana jalebi by food industry.

Fulltext Potential of non-thermal processing for food preservation in Southeast Asian countries

Mohd. Adzahan, N., Benchamaporn, P.

International Food Research Journal, 2007;14(3):141-152.
MyJurnal

The application of non-thermal processing technology (NTP) is increasing within the food industry. The absence of heat in this technology offer some advantages such as the sensory and nutritional attributes of the product remaining unaffected, thus yielding products with better quality compared to traditional processing methods. Suitability of technology for a certain application varies according to the nature of the reason and the purpose for processing. Some NTP has long been used in the food industry in Southeast Asia, but most are still at the initial stage of research. Despite several existing challenges, these technologies have the potential to be taken up as an alternative to processing of value-added food products especially now when consumer and trade demands as well as economic strength in the region is changing.

PMID: 30621881 DOI: 10.1016/j.fm.2018.11.005

Next Generation Sequencing (NGS) combined with powerful bioinformatic approaches are revolutionising food microbiology. Whole genome sequencing (WGS) of single isolates allows the most detailed comparison possible hitherto of individual strains. The two principle approaches for strain discrimination, single nucleotide polymorphism (SNP) analysis and genomic multi-locus sequence typing (MLST) are showing concordant results for phylogenetic clustering and are complementary to each other. Metabarcoding and metagenomics, applied to total DNA isolated from either food materials or the production environment, allows the identification of complete microbial populations. Metagenomics identifies the entire gene content and when coupled to transcriptomics or proteomics, allows the identification of functional capacity and biochemical activity of microbial populations. The focus of this review is on the recent use and future potential of NGS in food microbiology and on current challenges. Guidance is provided for new users, such as public health departments and the food industry, on the implementation of NGS and how to critically interpret results and place them in a broader context. The review aims to promote the broader application of NGS technologies within the food industry as well as highlight knowledge gaps and novel applications of NGS with the aim of driving future research and increasing food safety outputs from its wider use.

Fulltext Factors associated with occupational asthma among food industry workers: A systematic review

Md Zamri ASS, Saruddin MZ, Harun A, Abd Aziz SF, Aizad Za'bah AK, Dapari R, et al.

PLoS One, 2023;18(6):e0287040.
PMID: 37307252 DOI: 10.1371/journal.pone.0287040

INTRODUCTION: Occupational asthma (OA) is a type of Work-Related Asthma characterised by variable airflow limitation and/or inflammation due to causes and conditions attributable to a particular occupational environment, and not to stimuli encountered outside the workplace. There is an increasing need to extend the depth of knowledge of OA to better manage this condition, especially among food industry workers who are affected by it.
OBJECTIVE: This systematic review aimed to determine the factors associated with occupational asthma among food industry workers by electronically collecting articles from two databases (Medline and Scopus).
METHODS: This systematic review was prepared in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta Analyses) updated guideline. Two independent reviewers screened the titles and abstracts of the collected data, which were then stored in Endnote20 based on the inclusion and exclusion criteria. The included articles have been critically appraised to assess the quality of the studies using the Mixed Methods Appraisal Tool (MMAT).
RESULT: The search yielded 82 articles from Medline and 85 from SCOPUS, resulting in 167 unique hits. Only 22 articles have been included in the full-text assessment following a rigorous selection screening. Of the 22 articles identified, five were included in the final review. Several factors were found to have contributed to occupational asthma among food industry workers. They were classified into two categories: (1) work environment-related factors; and (2) individual factors.
CONCLUSION: Several work environment and individual-related factors were found to be associated with OA among food industry workers. A better understanding of the development of the disease and its potential risk factors is needed because it can affect worker's quality of life. Pre-employment and periodic medical surveillance should be conducted to assess and detect any possible risk of developing occupational asthma among workers.
