中文摘要:
      以猪脂为主要原料制备肉味香精前体物质，通过单因素实验和正交实验确定氧化反应的最佳条件。得到的氧化猪脂最佳反应条件是：氧化温度130℃，氧化时间3 h,VE添加量1.0%，不添加水和NaCl。在最佳反应条件下进行氧化实验，得到氧化猪脂的酸值(KOH)和过氧化值分别为1.549 mg/g和207.4 mmol/kg，肉味香精前体物质的感官评价分值为4.925。
英文摘要:
      The meat flavor precursors from pork fat by oxidization was studied.The optimal oxidization conditions were determined by single factor experiment and orthogonal experiment as follows: oxidization temperature 130℃, oxidization time 3 h, VE dosage 1.0%,without water or NaCl. Under these conditions, the acid value and peroxide value of the oxidized pork fat were 1.549 mgKOH/g and 207.4 mmol/kg respectively, and the sensory evaluation score of the meat flavor precursors was 4.925.
