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. |
