PANTOTHENIC ACID CONTENT IN CHINESE COMMON FOODS WITH ITS CONTRIBUTION TO DIETARY INTAKE
Objective Pantothenic acid content in Chinese common foods was determined,to support dietary intake evaluation.Methods A total of 109 food samples were collected from Beijing,Hainan,Tibet,Xinjiang and other places during the summer and autumn seasons of 2017-2019.After appropriate enzymatic hydrolysis,total pantothenic acid was determined by microbial method.Then average dietary intake of pantothenic acid was calculated,by combining classified foods data with Chinese residents'dietary consumption survey data in 2015-2017,and the contribution of various foods to pantothenic acid intake was preliminarily assessed.Results Pantothenic acid was detectable in all food samples.Its content in animal liver,eggs,legumes,bacteria,algae,or yeast,etc.was over 1 mg/100 g.The average intake of pantothenic acid in individuals aged 3-,6-,12-,18-,and>60 y was 3.2,4.3,5.1,4.7,4.4 mg/d,respectively.In addition,the everage intake in infants aged 0.5-1 was 1.0 mg/d.Cereals were the main contribution to adult dietary intake(48.8%).Conclusion This is the first release of pantothenic acid content in foods from China.The dietary intake of pantothenic acid by different age populations was calculated,in which cereals contributed the most.[ACTA NUTRIMENTA SINICA,2024,46(2):120-125]
