摘要
目的了解特殊医学用途配方食品原料复配维生素内维生素K_(1)在车间光照和加速试验下含量的变化情况。方法将复配维生素置于540 lx车间日光灯照射进行光照实验,分别在光照0、5、10、15、20、30、60和120 min后取样检测;将复配维生素置于温度(37±2)℃、相对湿度(75±5)%条件下进行加速实验,分别在第0、1、3个月取样检测。结果复配维生素在车间日光灯照射0~120 min维生素K1的衰减率均小于10%。在温度(37±2)℃、相对湿度(75±5)%条件下加速1、3个月后维生素K1衰减率均为-0.52%。结论复配维生素中维生素K1在光照2 h、温度(37±2)℃、相对湿度(75±5)%条件下加速3个月内较为稳定。
Objective To understand the changes in the content of Vitamin K_(1) in the vitamin compound as raw materials of formula foods for special medical purposes under workshop illumination and accelerated testing.Method The vitamin compounds were placed in a 540 lx workshop under fluorescent light for the illumination experiment,and the samples were taken for testing at 0,5,10,15,20,30,60 and 120 min of illumination.The vitamin compounds were placed at a temperature of(37±2)℃ and a relative humidity of(75±5)%,and the samples were taken for accelerated testing at 0,1,and 3 months,respectively.Result At 0-120 min of continuous illumination in the workshop,the attenuations of vitamin K1 were all less than 10%.At a temperature of(37±2)℃ and a relative humidity of(75±5)%,the attenuations of vitamin K1 were all -0.52%.Conclusion Vitamin K1 in the vitamin compound is relatively stable within 3 months of acceleration under conditions of 2 h of illumination,temperature of(37±2)℃,and relative humidity of(75±5)%.
