Effects of curing ingredients and nisin on product characteristics of Vawksa rep (smoked pork product)

Purpose – The purpose of this study is to evaluate the effect of curing ingredients (salt, sugar, nitrate and nitrite) and nisin as preservative on the storage stability of a traditional smoked pork product of Mizoram known as Vawksa rep, under different packaging conditions. Design/methodology/approach – Meat cuts (preferably ham) were cut into small pieces of uniform size and allotted to four different treatment groups, namely, T1 (Traditional Vawksa rep + Aerobic packaging); T2 (Traditional Vawksa rep + Vacuum packaging); T3 (Modified Vawksa rep + Aerobic packaging) and T4 (Modified Vawksa rep + Vacuum packaging). Vawksa rep is traditionally produced by light smoking of pork chunks. Modification was carried out by applying curing prior to smoking and applying nisin to the pork chunks after smoking and before packaging. The products were compared on the basis of physicochemical, microbiological, proximate composition and sensory qualities at five days interval under refrigerated (4 ± 1°C) conditions. Fi...

Drumstick (Moringa Oleifera) as a food additive in livestock products

Purpose – The purpose of this paper is to focus on natural food additives identified in the drumstick (Moringa Oleifera) and their probable application as novel ingredients in the development of functional food products. This plant additive has attracted interest as one of the prominent candidates for the purpose of improving processing, quality and the safety of various livestock foods such as meat, milk, fish and their products. The search of natural food additives for the processing and preservation of high-quality, ready-to-eat products has notably increased due to the adverse effects of chemical additives on human health. Design/methodology/approach – Traditionally, Moringa is a pan-tropical plant species, which is well-known for its nutritional and medicinal properties in human nutrition. Its leaves, seeds, flowers, pods (fruit), bark and roots are extremely valuable sources of nutrition for people of all ages. Moringa is nowadays also considered as an important source of nutraceuticals which may fi...

Prevention of lipid oxidation in muscle foods by milk proteins and peptides: A review

ABSTRACT Muscle foods (especially fresh meat, precooked, and restructured meat products) are highly prone to lipid oxidation, which ultimately leads to certain problems, viz. discoloration, off-flavor, drip losses, loss of essential fatty acids and vitamins, and generation of toxic products. These problems can be minimized with the help of various agents and or techniques such as use of natural/synthetic antioxidants, metal chelating agents, physical conditions, vacuum packaging, and encapsulation techniques. Among these, the role of synthetic antioxidants is quite debatable due to certain health risks to humans. Among the natural molecules, milk proteins and their bioactive peptides offer a promising potential for the meat industry. Various forms of milk proteins and peptides including caseinates, whey proteins, skim milk, and milk co-precipitates can be used to prevent lipid oxidation in meat products either in the form of added ingredients or as edible coatings. However, in addition to prevention of lipid oxidation, they also provide nutritional benefits and improve the technological processing and shelflife of meat and meat products. This review focuses on the utilization, mechanism of action, and efficacy of milk proteins and peptides to inhibit lipid oxidation in muscle food products.

Effect of curing ingredients and vacuum packaging on the physico-chemical and storage quality of ready-to-eat Vawksa rep (smoked pork product) during refrigerated storage

Aim: The present study was conducted for the development of ready-to-eat Vawksa rep (smoked pork product) and to study the synergistic effect of curing ingredients and vacuum packaging on the physico-chemical and storage quality during refrigerated storage at (4°C±1°C) for 15 days. Materials and Methods: Four different batches of Vawksa rep samples were prepared, i.e., T-1 (uncured, first cooked at 121°C for 15 min, and then smoked at 120°C for 30 min), T-2 (uncured, cooked, and smoked simultaneously at 120°C for 45 min), T-3 (cured, first cooked at 121°C for 15 min, and then smoked at 120°C for 30 min), and T-4 (cured, cooked, and smoked simultaneously at 120°C for 45 min). Results: Cooking yield was significantly higher (p<0.05) for the T-4. The pH of T-3 and T-4 samples was significantly higher (p<0.05) on day 15. The tyrosine value of all the samples increased significantly (p<0.05) among the different days of analysis. Thiobarbituric acid value was significantly (p<0.05) lower in T-3 sample both at the beginning and at the end of storage period. In microbiological profile, total plate count was lower in T-3 and T-4 than T-1 and T-2. However, Escherichia coli count was negative for T-3 and T-4 samples throughout the storage period. Among sensory attributes, T-3 and T-4 samples registered superior scores for color, flavor, texture, juiciness, and overall acceptability. Conclusion: Furthermore, Vawksa rep (smoked pork product) could be prepared easily with little technology up-gradation and with a negligible escalation of production cost.

Development and quality characterization of mutton snack

Purpose – The aim of this study was to explore the feasibility of formulation, quality characterization and acceptability of rice flour- and black gram flour-incorporated mutton snack among consumers. Cereal-based snacks, which have very less nutritional value, are highly popular among Indian consumers. Malnutrition and protein deficiencies can be overcome by supplying nutrient-dense meat-incorporated cereal-based snacks to them. On this background, it was planned to incorporate easily available sheep meat to popular snack to improve the nutritional quality, acceptability and functionality of traditional snack. Design/methodology/approach – Mutton-based snack formulation was standardized; rice flour (Treatment-I [T-I]), black gram flour (Treatment-II [T-II]) and their combination (Treatment-III [T-III]) were used along with lean meat for the preparation of mutton snack. Microwaving and frying process of cooking was applied, and various physicochemical and sensory properties of both raw and cooked snack we...
