Quality And Shelf Life

This study provides an application of new, natural source of crude peptide extract from Lablab bean (CPL). Use of additive such as benzoate in the rice noodle industry is a common practice and has several bene?cial effects on quality and shelf-life. However, the shelf-life of semi-dried rice noodles can be extended by crude peptide extract with acceptable quality when compared to other additives. This research aimed to extract CPL and determine its effect on the growth of microorganisms. The use of the CPL to extend the shelf-life of semi-dried rice noo-dles was compared with other natural extracts (chitosan and thymol) and benzoic acid. The CPL samples were extracted using 5% pepsin and incubated for up to 24 h. CPL at 200 mg/mL could be used as the growth inhibitor for Bacillus cereus but not for Staphylococcus aureus and Escherichia coli. It was found that noodles with CPL had the highest cooking loss (4.69) and lowest tensile strength (22.6 g.force). Overall-liking scores showed slightly liked (6.0 out of 9) and 68% of the consumers accepted the CPL-treated noodles. Shelf-life testing showed that CPL could extend the shelf-life of the noodles for 3 days than the control (1 day). Using 200 mg/mL of CPL could extend the shelf-life more than 3 times when compared to the control noodle (no additive). The CPL was nearly as effective as benzoic acid that could be kept for 3 days. Hedonic score in overall-liking showed a slightly like (6.2) for the noodles with CPL. This study suggests the application of adding CPL could be used as new natural additive and seems to be promising to apply in many food products such as pasta or sausages.

Quality And Shelf Life

In the present study, influence of two types packaging (inflated polypropylene (IPP) and laminated aluminium foil (ALU)) and storage conditions (with/without 1 g of silica desiccant packets (SDPs)) on quality and shelf life of chewy santol candies were studied. After storage at 25 degrees Celsius for 30 days, it was found that the combination of ALU with SDPs presented the best treatment to maintain the quality of colour, water activity (aw), moisture content, total acidity, pH value, sensory evaluation i.e. (colour, odour, flavour and overall acceptance). Shelf-life prediction by using accelerated Q10 method based on moisture factors as an indicator of deterioration of the samples during storage. The samples were incubated at 25, 35 and 45°C and sampled every 5 days for estimated on physical, chemical quality and microbiological change. The predicted shelf life of chewy santol candies at 25°C of IPP and ALU packaging with SDPs using Q10 method were 25 and 27 days, respectively. However, the IPP and ALU packaging without SDPs, the products can be stored less than 25 days. SDPs provides a cheaper and easy method to keeping quality of the chewy santol candies. Therefore, the products with SDPs packaging can maintain the product quality during storage and has an acceptable quality to consumers.

Background: Instant pumpkin cream soup enriched with tempeh had fulfilled 10% Recommended Dietary Allowances (RDA) for elderly so that it can be used as an easy-to-serve snack, but decreasing quality of instant cream soup will be happened if the instant cream soup was stored for a long time. Objectives: This study aimed to analyze quality of water content, water activity and lipid oxidation in instant pumpkin cream soup during storage and estimated the shelf life of pumpkin cream soup enriched with tempeh.Method:  Quality storage was analyzed using of water content, water activity (aw) and lipid oxidation. Estimation of shelf life was analyzed using Arrhenius Accelerated Shelf Life Testing (ASLT) model.Results: The results showed that the water content, aw levels and lipid oxidation of instant pumpkin cream soup increased during the storage period. The critical parameter used in this study was lipid oxidation. Instant cream soup without the addition of tempeh can last 447 days  while the cream soup with the addition of tempeh has a shelf life of 433 days.Conclusion: Quality of instant pumpkin cream soup decreased during the storage period and it would be expired over a year.
