Get PDFStreet food in Malaysia is gaining popularity due to its competitive pricing and accessibility for consumers. However, unsanitary methods and processes have raised concerns about foodborne diseases, making it a major food safety concern. This study aims to: 1) investigate the levels of food safety knowledge, attitudes, and practices among street food vendors; 2) determine the associationbetween demographic characteristics and food safety practices; and 3) investigate the factors influencing food safety practices among these vendors. The study was conducted in the Klang Valley area, and a purposive samplingmethod was used to select 268 street food vendors. Descriptive, Chi-square, and logistic regression analyses were conducted to analyse the data. The findings reveal that most street food vendors possess adequate knowledge, favourable attitudes and follow food safety practices. Key factors influencing food safety practices included knowledge, attitudes, education level, type of stall, monthly revenue, food safety training, and typhoid injection. Most notably, monthly revenue emerged as a significant factor, where vendors with higher incomes were more likely to implement good food safety practices. Hence, authorities should offer incentives such as equipment procurement subsidies and microcredit schemes to street food vendors to empower them to overcome financial constraints and invest in necessary practices that ultimately lead to improved food safety standard

Characterization of resistant starch (type III) produced from banana (Musa acuminata x balbisiana CV Awak) pseudostem
Get PDFBanana (Musa acuminata x balbisiana cv. Awak) contains minerals, vitamins, fiber, proteins, carbohydrates, and other vital nutrients. Unfortunately, the banana pseudostem are left as a waste after harvesting. It is rationale to process banana pseudostem into useful product such as functional food ingredients for the application of food industry. The present study aimed to determine the functional properties of resistant starch (type III) produced from banana pseudostem as well as to observe the morphology of resistant starch produced. The native starch from banana pseudostem was isolated and processed into resistant starch (type III) by autoclaving process. The characterization of resistant starch of banana pseudostem (RSBP) was compared with native banana starch and commercial starch (i.e., corn and potato starches) in terms of functional group, crystalline structure, paste clarity, pH, freeze thaw stability, particle size distribution, and morphology. The results showed that the hydroxy, alkene, carbonyl, and alkane groups were found presence in all the evaluated starches. However, the sulphate group was only existed in RSBP. Moreover, RSBP obtained a B-type crystalline structure. Native starch of banana pseudostem exhibited a smooth surface devoid of dents with a mixture of irregular granule shapes of oval, spheroid, and elongated granule shape. All the evaluated starches were categorized as acidic food ingredient. Potato starch exhibited the highest value for paste clarity and particle size distribution. RSBP had significant higher freeze thaw stability than other starches. Banana pseudostem can be considered a feasible low-cost raw material for production of resistant starch (type III) then, a suitable functional food can be developed, depending on the desired end-product quality
