摘要: 对原花青素对丙烯酰胺形成-消除动力学的影响进行研究。在荔枝原花青素(litchi pericarp procyanidin, LPPC)和莲房原花青素(lotus seedpod procyanidin,LSPC)对丙烯酰胺最大抑制率添加条件的基础上,分别采用 Logistic-生长曲线模型、Logistic-Fermi动力学模型和Logistic-指数动力学模型描述丙烯酰胺的形成-消除动力学过 程,最终优化选择Logistic-指数动力学模型为描述对象。实验结果表明:两种原花青素对丙烯酰胺形成过程具有显 著性影响,且LSPC的作用大于LPPC,在反应后期,两种原花青素对丙烯酰胺抑制均无显著性影响。

Abstract: The effect of procyanidins on the formation and elimination kinetics of acrylamide was investigated. The concentrations of litchi pericarp procyanidin (LPPC) and lotus seedpod procyanidin (LSPC) for the maximum percentage inhibition of acrylamide were determined, and then the kinetic process of acrylamide formation and elimination was described by the Logistic-growth curve, Logistic-Fermi and Logistic-exponential kinetic models. The Logistic-exponential kinetic model was found to be the best among these models. The experimental results showed that both LPPC and LSPC had a significant impact on the formation of acrylamide, especially LSPC; however, they had no significant inhibitory effect at the later stage of reaction.
