复配营养强化剂中维生素A和α-维生素E皂化液的稳定性考察

Study on the Stability of Vitamin A and Alpha-Vitamin E Saponified Solution in Compound Nutritional Fortifier

食品复配营养强化剂中的维生素A和α-维生素E通常采用GB 5009.82—2016中方法检测,样品需要经过60℃水浴皂化,检验步骤较复杂。基于此,本文对复配营养强化剂中维生素A和α-维生素E皂化液的稳定性进行了考察。结果表明,样品的皂化液放置时间对维生素A含量测定结果影响较小,对α-维生素E含量测定结果影响较大。

Vitamin A andα-vitamin E in food compound nutritional fortifier are usually tested by the method in GB 5009.82—2016.The samples need to be saponified in a 60℃water bath,and the testing steps are complicated.Based on this,the stability of vitamin A andα-vitamin E saponified solution in compound nutritional fortifier was investigated in this paper.The results show that the storage time of the saponified solution of the samples has little effect on the determination results of vitamin A content,but has a greater impact on the determination results ofα-vitamin E content.
