Objective: This study was carried out to investigate physicochemical properties, and antioxidant and antimicrobial activities of low-fat sausages (LFSs) covered with sodium alginate (SA) film alone and with powder film (TSA-film) formed by cross-linking cherry tomato powder (CTP) and SA with calcium chloride (CaCl2).Methods: Sausages covered with the biodegradable film were assessed based on the measurement of pH, color (L*, a*, b*), proximate analysis, expressive moisture (EM), texture profile analysis, total plate counts (TPC), violet red bile, and 2-Thiobarbituric acid reactive substances (TBARS) during storage under refrigeration. LFSs wrapped with TSA-film were compared with those wrapped with SA-film and without film (control) during storage at 10°C for 35 days.Results: The LFSs covered with the mixed film had lower pH, lightness (L*), EM%, TBARS, and TPC, but lower yellowness (b*) and hardness values than those wrapped with TSA-film alone.Conclusion: Lipid oxidation and microbial growth was retarded in sausages covered with biodegradable films, especially multiple films as compared to single film, thereby resulting in extended shelf-life of the LFSs.

The Common

The common squid (Todarodes pacificus) is one of the most widely consumed food ingredients in East Asian countries, especially Korea and Japan. It is generally marketed raw, which leads to inconvenient preparation, less commercial value, and short shelf life. Therefore, in order to handle these problems, superheated steam roasting (260°C heater, 240°C steam for 4 min) in combination with smoking treatment (15 min) using sawdust from the oak tree was used to process squid before mixing with vegetables and special sauce to make a ready-to-eat squid dish in an effective packaging. The processed squid product showed favorable sensory characteristics (appearance, odor, color, flavor, and texture) and physicochemical properties including maintained pH level (pH > 6.4), low microbial activity (4.74 ± 4.27 log CFU/g), low VBN level (18.27 ± 0.52 mg%), and good texture profile during storage for 10 days at 10°C. Results were significant at the significance level of p<0.05. Findings of this study suggest that the superheated steam-roasting treatment was the best method to maintain nutritional value of the common squid. It also showed favorable sensory and physicochemical properties, while smoking treatment prolonged the shelf life through enhancing antioxidant and antimicrobial activities and enriched flavor of the squid product.

ABSTRACT Tartary buckwheat peptides (TBPs), produced from tartary buckwheat through solid-state fermentation, were used as a dip treatment solution to preserve tilapia fillets. Fillets were dip treated with different concentrations of TBPs (0.5, 1, and 2% [v/v]) and stored at 4°C for 12 days. The effect of TBPs on thiobarbituric acid, total volatile base nitrogen, surface color, texture profile analysis, total viable counts, and changes in sensory properties of tilapia fillets during storage was investigated. Compared with the control group, the groups treated with TBPs displayed reduced rates of quality deterioration in physicochemical, bacteriological, and sensory characteristics. Based on total volatile base nitrogen content, total viable counts, and sensory scores, the shelf life of control tilapia fillets was 4 days and that for TBP-treated fillets was 8 days, twice as long as that of the control group. Thus, TBPs can be used as preservatives to maintain the quality and extend the shelf life of tilapia fillets stored at 4°C.

Restructuring by adding Sodium Alginate or Microbial Transglutaminase (MTGase) using cold gelation technology make it possible to obtain many different raw products from minced and/or chopped fish muscle that are suitable for being used as the basis of new restructured products with different physicochemical properties and even different compositions. Special consideration must be given to their shelf-life and the changes that may take place during chilling, both in visual appearance and physicochemical properties. After chilled storage, the restructured models made with different muscular particle size and composition at low temperature (5 °C), it was observed that microbial growth limited the shelf-life to 7-14 days. Mechanical properties increased (p < 0.05) during that time, and higher values were observed in samples elaborated by joining small muscle particle size than in those elaborated by homogenization. There was no clear increase in the cooking yield and purge loss, and no significant colour change (p > 0.05) was detected during storage.

Energy Bar

The food industry needs a creative approach to innovation in order to produce revolutionary materials, innovations and fresh, nutritious, sustainable food products. Tempeh is a traditional meal prepared using Rhizopus oligosporus to ferment dehulled and cooked soybeans to a compact and sliceable cake. Because of their high content of proteins, carbohydrates, lipids, and minerals, energy bars are snacks offering good sensory and nutritional properties. Canavalia ensiformis (Kacang Koro), is an underutilised legume that contains up to 32% of protein. To our knowledge, no prior studies have studied regarding tempeh and energy bars, especially in Malaysia. This research aimed to evaluate both the physicochemical properties and sensory acceptance of the C. ensiformis tempeh energy bar. Energy bars of six formulations (Formulation A – E) were produced using different percentages of C. ensiformis tempeh namely 0%, 4.8%, 9.5%, 14.3%, 19.0% and 23.8%. The physical characteristics of the energy bar were analysed based on colour profile analysis, texture analysis and also the pH value, while the chemical characteristics were analysed based on proximate analysis, calories, mineral content, and toxicity analysis. The results showed that the energy bars consist of moisture content of 9.29-13.09%, ash of 0.99-1.56%, crude fibre of 1.82-7.27%, protein of 4.93-10.34%, crude fat of 12.36-15.97%, carbohydrate of 58.91-64.94%, and calorie content of 4627.55 - 5267.80 cal. Energy bars with 23.8% of C. ensiformis tempeh exhibited highest in moisture and protein, moderate in ash and fibre and showed no significance in carbohydrate and fat contents. The taste and overall acceptability indicate that formulation A showed the best acceptance among the prepared formulations. The utilization C. ensiformis tempeh could diversify the usage of C. ensiformis in the food industry, hence promoting their application.

The demand for healthy and ready-to-eat products, such asfreshly-harvested fruits, has been growing steadily over the years. However, these products are very susceptible to spoilage and have a short shelf-life. In this research, edible coatings based on sodium alginate and its blends with ascorbic acid (a natural antioxidant and anti-browning agent) were applied on fresh-cut pineapple samples, and the changes in their physicochemical properties were monitored during 10 d of storage at 4ºC. Initially, the surface of the coated fruits was brighter and statistically significant differences were not found between uncoated and coated samples (P<0.05); similar values were obtained in the parameters of soluble solids (~11 ºBrix), pH (~3.74) and titratable acidity (~0.64%). During storage, coated samples were more protected against changes in appearance compared to uncoated fresh-cut pineapple samples. The current results will be beneficial for further research that focuses on the preservation of minimally processed fruits such as pineapple.
