摘要
采用60Co-γ分别对天冬酰胺、葡萄糖进行辐照处理后,将其混合得到天冬酰胺-葡萄糖模拟体系,分别在不同的油浴温度和时间下使其发生反应,研究辐照剂量对模拟体系中丙烯酰胺的生成量和褐变程度的影响,并建立褐变程度与丙烯酰胺生成量的相关性。结果表明:随辐照剂量的增大,丙烯酰胺的生成量呈现先减小后增大的趋势;60Co-γ不同剂量预处理后的天冬酰胺-葡萄糖的模拟体系在高温油浴中反应后,褐变程度与丙烯酰胺的生成量之间有一定的相关性。
In this work,asparagine-glucose model system was reacted under different temperature and time in the oil bath after asparagine and glucose pretreated by 6~Co-y irradiation, respectively.The effect of irradiation dose on the formation of acrylamide,the browning and the correlation between browning and acrylamide of the model system during reaction were studied.The results indicated that the acrylamide amount was decreased firstly and then increased with the irradiation dose increasing.There was a good linear correlation between acrylamide content and the browning degree in the glucose-asparagine model system during reaction after Gamma-Ray （^60Co） pretreatment.
