|
For the purpose of improving quality of defrosted-frozen chicken leg, beef and yellow corvina, the effects of height(0㎜ : H0, 5㎜ : H5, 10㎜ : H10, 15㎜ : H15) for microwave defrosting on their physicochemical properties were investigated. In frozen chicken leg, color values were not significant different between each treatment while H10 and H15 had the highest score on appearance. Hardness of defrosted chicken leg was increased as height increased. In frozen beef, temperature of beef after defrosting increased as height increased and H10 had the highest appearance score. In frozen yellow corvina, H10 had the highest hardness and appearance scores. Physicochemical properties of color, texture and appearance of microwave-defrosted frozen food were changed by height within microwave oven.
