Study On The Formation Regulation And Control Technology Of Heterocyclic Aromatic Amines During Meat Processing

The formation regulation and the control technology of3species HAs in fried pork was studied in this research. The pork was choosen as the investigated object in this study, which is the most-consuming broiler layer in China. The formation regulation of3species HAs under different processing conditions was studied, and the control technology of it was explored and optimized, thereby, the basis of further research on the HAs compounds formation mechanism and control technology in the food processing was provided.According to the research, the quantity of these3species HAs become more as the temperature raises; the time goes; and the surface area expands,. What’s more, the quantity of PhIP in HAs compared to be the largest under the same conditions. And the quantity of these3species HAs in fried pork were:MelQx3.278ng/g;4,8-DiMeIQx0.617ng/g; PhIP19.213ng/g (180℃,5min).The HAs’generation could be inhibited by many antioxidants. And the main purpose of this research was to discover the inhibiting effects of different antioxidants on the HAs in fired pork so as to select the optimal antioxidant and further optimized its inhibition conditions. From this paper, it was found that the natural antioxidants shows hett inhibiting effects than synthetic antioxidants in common. Among all the selected antioxidants in this paper, Best inhibition effect was showed by the extrat of the bamboo leaves(AOB),with the optimized condition, the respective inhibition rate of3species HAs were:MelQx (0.2g/kg,65.2%);4,8-DiMeIQx (0.01g/kg,67.2.%).PhIP (0.100g/kg,57.5%).The glucose, amino acid and creatinine was choosen as the precursors in the chemical model system,The species and amount of the HAs were decided by the species of creatinene, the proportion amount of the precursors,the temperature, time, species of the solution, etc.. In this paper, all three HAs could be detected in the model of2mmol glycine and1mmol glucose, the respective quantity of these three HAs were:MeIQx1.950ng/mmol glycine;4,8-DiMeIQx6.998ng/mmol glycine; PhIP4.663ng/mmol glycine (180℃,10min). On the contrary, in the (?)del system, only one specie of HAs could be detected.but the amount was mu(?)arger,for example, the quantity of PhIP in the diglycol solution system in the model of40mg phenylalanine and26mg creatinine was2.570μg/mmol phenylalanine (200℃,60(?)...
