食品添加剂乳酸链球菌素的摄入量评估研究

目的进行乳酸链球菌素的摄入量评估研究,了解我国居民的乳酸链球菌素摄入情况,为采取恰当的管理措施提供科学依据。方法以2002年全国居民营养调查获得的人群食物摄入量数据和《食品添加剂使用卫生标准》(GB2760—2007)中规定的乳酸链球菌素允许使用的食品类别、最大使用量作为数据来源,利用点评估方法计算我国居民乳酸链球菌素的摄入量。按照不同的年龄、性别、地区组合将人群分为27组,分别计算食物摄入量平均值和第97.5百分位数(P97.5)情况下各组人群乳酸链球菌素的摄入量和各类食物对摄入量的贡献率。结果在食物摄入量为均值的情况下,各组摄入量占每日允许摄入量(ADI)的比例为1.49%～17.16%。在食物摄入量为第97.5百分位数的情况下,各组乳酸链球菌素摄入量为该组ADI的9.35%～77.95%。在食物摄入量为均值和食物摄入量为第97.5百分位数的情况下,乳制品和预制肉制品是乳酸链球菌素摄入量的主要来源。结论无论在食物摄入量为均值情况下还是在食物摄入量为第97.5百分位数的情况下,各组乳酸链球菌素膳食摄入量均未超过其ADI,表明按照目前标准规定使用该添加剂是安全的。

Safety Assessment on the Consumption of Food Additives Nisin in Diets

O b jective To understand the consumption of n isin in Ch ina and provide sc ientific support for theadm in istration of food add itives1M ethod The food in take data were obta ined from the N ational Survey on Nutrition andH ealth Status ofCh inese Peop le in 20021 The food category perm itted to use nisin and the upper lim it for use in each foodca tegory was obta ined from theH yg ienic Standa rds for Using Food Additives (GB 2760) 2007) . The poin t estimateme thodwas used to calcu late the consumption of n is in ofCh inese people. The peoplewere d ivided into 27 groups accord ing to the irage, sex and living area. The nisin consumption of peoplewhose food intake at the average level and whose food intake atthe 971 5th percen tile level of each group was calculated. The contribution of each food category to the nisin consump tionwas a lso ca lcu la ted. R esults Wh ile the food intake at average level the da ily n is in consumption was from 11 49% to17116% of the acceptab le da ily intake ( ADI). While the food intake at the 9715th percentile level the da ily n isinconsumption was from 91 35% to 77195% ofADI. Dairy products and preprocessedmeat products are themain con tributorsto the consumption of nisin. Nomatter the food intake at average level or a t the 971 5th pe rcentile level the da ily n isinconsumption of all groupswas less than theAD I.
