摘　　要：美拉德反应副产物影响人体健康,特别是婴幼儿,在母乳喂养不足的情况下,乳粉是婴幼儿主要的营养和能量来源,美拉德反应影响赖氨酸的吸收。该研究针对市场常见国内及进口婴幼儿产品,对产品中的糠氨酸(furosine)、5-羟甲基糠醛(5-hydroxymethylfurfural,5-HMF)、乙二醛、丙酮醛、2,3-丁二酮、羧甲基赖氨酸(carboxymethyl lysine,CML)、羧乙基赖氨酸(carboxyethyl lysine,CEL)等美拉德反应副产物进行测定,对产品颜色褐变指数及荧光强度进行分析,综合评估各种婴配粉中美拉德反应各阶段的产物含量以及贮藏时间对其的影响。研究发现不同品牌婴配粉美拉德反应程度存在差异,这与生产的工艺条件和理化成分含量有一定关系,故应在优化产品工艺的同时,控制美拉德反应程度,降低潜在有害副产物的产生。此外,市售婴配粉在储藏过程中美拉德反应仍在进行,在储藏后期不同反应阶段副产物含量变化存在差异,建议购买生产日期新鲜的市售婴配粉,产品的质量与安全系数高。Maillard reaction is a common chemical change during heat treatment of dairy products,and its by-products affect human health.Infant formula is a major source of nutrition and energy for infants and young children,especially when breastfeeding is insufficient.However,the Maillard reaction affects lysine absorption.This study aimed to analyze the contents of Furosine,5-hydroxymethylfurfural(5-HMF),glyoxal,methylglyoxal,2,3-butanedione,carboxymethyl lysine(CML),carboxyethyl lysine(CEL),and other by-products of the Maillard reaction using the common domestic and imported commercial infant products.The color Browning index and fluorescence intensity of the products were analyzed.Moreover,the effects of storage time on the content of products in different stages of the Maillard reaction of the infant formula were evaluated comprehensively.The results showed that the Maillard reaction was still carried out during the storage process of commercial infant formula,and there were changes in the content of by-products in different reaction stages at the later stage of storage.For this reason,fresh commercial infant formula with high quality is the best choice for consumers.
