Abstract: 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.
