Abstract
In order to establish the optimal thawing condition of frozen fork, hot-air thawing and microwave thawing were evaluated at various conditions. In hot-air thawing, the higher the air temperature and the lower the meat surface temperature, the grater the thawing rate was. In microwave thawing, the grater the power and the lower the meat core temperature, the faster the thawing rate was. Comparing the two methods, microwave thawing was found to be significantly faster than hot-air thawing. TBA value and cooking loss were higher in hot-air thawing than that of refrigeration thawing or microwave thawing. Total extractable protein tended to be lower in hot-air thawing than that of the other two thawing methods. WHC decreased with the increase of hot-air and meat surface temperature whereas no significant difference was observed in microwave thawing regardless of the thawing conditions. Total microbial counts of thawed meat by the hot-air or microwave thawing were lower than that of refrigeration thawing.
여러 가지 해동방법 중에서 비교적 급속해동을 할 수 있는 열풍해동방법과 microwave 해동방법으로 냉동 돈육을 해동하여 해동육의 이화학적 성질을 조사하였으며,
