摘要
油炒是中式菜肴典型烹饪方式之一,中心温度是判断肉类熟度的核心参数。油炒预制后再进行复热食用,存在品质劣化问题。该研究以猪里脊肉为原料,以中心温度(40~85℃)为熟度分级标准,在恒温油浴(150℃)条件下制备不同油炒预制熟度的猪肉并微波复热至安全食用条件(72℃),分析不同油炒预制熟度对猪肉食用品质和体外消化特性的影响。结果表明,随着油炒预制熟度增加,L^(*)值显著减小、a^(*)值显著增加(P<0.05),褐变程度加剧使肉品色泽暗淡;剪切力呈先增加后减少趋势,硬度及咀嚼性显著增加(P<0.05),不利于保留肉品柔嫩口感;感官评价结果显著降低(P<0.05)。在不同油炒预制熟度组中,一级油炒预制熟度的蛋白消化率和水解度最高(65.63%,59.31%)、平均粒径最小(30.63μm),多肽含量最多(5.91 mg/mL)。综上,低油炒预制熟度猪肉在经微波复热后有利于保持肉制品色泽、嫩度,有利于人体消化吸收。
Stir-fry is one of the typical cooking methods in Chinese dishes.The center temperature is the core parameter for determining the degree of doneness.Stir-fry prepped in oil and then reheated for serving,it exists a problem of quality deterioration.The raw material is pork loin,the doneness grading standard is center temperature(40-85℃).The pork with different stir-fry prepared doneness prepared under the condition of constant temperature oil bath(150℃),and then reheated by microwave to safe consumption condition(72℃),to analyze the effect of different stir-fry prepared doneness on the edible quality and in vitro digestive characteristics of pork.With the increase of stir-fry prepared doneness,the L^(*)value decreased significantly and a^(*) value increased significantly(P<0.05),the browning degree intensified to make the meat color dull;the shear force increased and then decreased,the hardness and chewiness increased significantly(P<0.05),it is not good for the retention of meat tenderness;organoleptic evaluation results decreased significantly(P<0.05).In different stir-fry prepared doneness groups,the first grade of stir-fry prepared doneness has the highest protein digestibility and hydrolysis(65.63%,59.31%),the smallest average particle size(30.63μm),and the highest polypeptide content(5.91 mg/mL).In summary,it shows the low stir-fry prepared doneness is beneficial to maintain the color and tenderness of the meat products after microwave reheating,it is beneficial to the human body’s digestion and absorption.
