Abstract：Objective To understand the changes in the content of Vitamin K1 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)%.
