摘　　要：采用葡萄糖/天冬酰胺低湿模拟体系,系统研究反应条件对丙烯酰胺形成的影响。在单因素试验的基础上,选取加热温度、加热时间、天冬酰胺添加量、葡萄糖加入量4个因素,进行响应面优化分析。结果表明:加热温度和天冬酰胺添加量对丙烯酰胺的产生量影响显著。葡萄糖和天冬酰胺添加量分别为1.2 mmol,丙烯酰胺最大产生量条件为:加热温度200°C,加热时间6.5 min,丙烯酰胺的最大理论生成量为674.0 nmol。The effect of reaction conditions on the acrylamide formation was studied by low - moisture glu-cose/asparagine simulation system. The 4 factors, heating temperature,time, the asparagine and glucoseaddition levels, were optimized and analyzed by response surface based on single factor test. The resultsshowed that heating temperature and asparagine content had significant influence on the formation of ac-rylamide. In addition, when both of the addition levels of asparagine and glucose were 1.2 mmol, heatedat 200 ℃ for 6.5 min, the maximum content of acrylamide was 674.0 nmol.
