Influence of Freeze Thaw Cycle Abuse on Quality Attributes of Chevon During Storage |
|
Description |
The practical approach of present study was to evaluate effect of multiple freeze thaw cycles in combination with effect of different thawing methods in chevon. The Indian meat industry constantly in search of measures to mitigate quality problems associated with multiple freezing-thawing. In present study chevon was subjected to three multiple freeze thaw cycles and thawed either at refrigeration temp (overnight time) or hot water temp (40±1°C) or room temp (35±2°C). The chevon thawed after each freeze thaw cycle was evaluated for physico-chemical changes (pH, WHC, ERV, aw, TBA, tyrosine value), proximate analysis (moisture, protein), microbial analysis (TPC, Psychrophilic count, E. coli and Salmonella), sensory analysis, histological morphology and myofibrillar protein isolation and SDS-PAGE. It was observed that TBA, Tyrosine values were significantly increased whereas WHC decreased as freeze thaw cycles were increased. Certain, histological changes were found in different freeze thaw cycles. The study revealed that microbial load increased in every freeze thaw cycle and maximum TPC count was observed in room temperature thawed chevon as compare to other method of thawing in different freeze thaw cycles. The sensory evaluation revealed non significant variations in all the sensory attributes throughout the study. The SDS-PAGE results revealed that there were significant effects on Troponin (80kDa) protein in hot water thawed chevon in 2nd and 3rd freeze thaw cycles. Also, as number of freeze thaw cycles increased low molecular weight bands increased due to breakdown of larger molecular weight protein. |
