牛奶中泛酸含量测定

摘要

目的：对牛奶中泛酸的本底含量进行测定,为乳制品中泛酸的强化提供数据支持。方法：选取大量牛奶样本,通过微生物法和高效液相色谱法对泛酸含量进行测定。结果：牛奶中的泛酸含量大约为253～502μg/100mL,平均值为365.9μg/100mL。结论：乳制品中强化泛酸可以依据上述数值参考添加。%Purpose： To determine pantothenic acid content in milk so as to provide data supports for fortifying milk with pantothenic acid.Methods： Large samples of milk were collected and determined for their pantothenic acid content by the microbiological method and HPLC,respectively.Results： The content of pantothenic acid in milk was approximately between 253μg/100 mL and 502μg/100 mL with an average of 365.9μg/100 mL.Conclusion： This study can provide useful references for pantothenic acid fortification of milk.
