干法婴幼儿配方奶粉货架期内维生素衰减研究

Study on Vitamin Decay during Shelf Life of Dry Method Infant Formula

本文研究了干法婴幼儿配方奶粉中维生素在24个月货架期内的衰减率。结果显示,衰减最明显的是维生素B_(1)和维生素D,平均衰减率均高于20%;其次是维生素A、维生素E、维生素K_(1)、维生素C,平均衰减率为12.91%~19.78%;维生素B_(6)、维生素B_(12)、叶酸、泛酸的平均衰减率低于精密度,未发生明显衰减,其余维生素未发生衰减。本研究旨在为干法婴幼儿奶粉配方设计提供一定的参考。

This paper studies the decay rate of vitamins in dry-process infant formula milk powder during the 24-month shelf life.The results show that vitamin B_(1)and vitamin D have the most obvious decay,with an average decay rate of more than 20%;followed by vitamin A,vitamin E,vitamin K_(1),and vitamin C,with an average decay rate is 12.9_(1)%to 19.78%;the average decay rate of vitamin B_(6),vitamin B_(12),folic acid,and pantothenic acid is lower than the precision,and no obvious decay occurs,and the remaining vitamins do not decay.This study aims to provide a certain reference for the design of dry-process infant formula milk powder.
