Investigation of the endogenous benzoic acid background content in Chinese Douchi
摘要
Abstract
A total of 161 samples of Douchi were collected from major production areas in China,including Chongqing,Yangjiang in Guangdong,Liuyang in Hunan,Jiangxi,and Chengdu in Sichuan,covering various stages of the production process.The content of benzoic acid was measured using high-performance liquid chromatography in accordance with national standards.The results revealed that the average content of benzoic acid in 69 finished Douchi samples was 9.16 mg/kg,while the average content in 92 intermediate products from various production stages was 6.40 mg/kg.The benzoic acid content in moldy Douchi was significantly higher than that in Aspergillus Douchi,regardless of whether in finished or intermediate products.There were significant regional differences in benzoic acid content among the five major production areas,with Jiangxi showing the highest levels,followed by Hunan,Guangdong,whereas Sichuan and Chongqing had comparatively lower levels.Detection results for intermediate products collected at various stages indicated the presence of endogenous benzoic acid during the koji-making stage.In moldy Douchi,the content increased with the advancement of the production process,while in Aspergillus Douchi,it primarily occurred during the koji-making phase and the first ten days of fermentation.It was recommended to use 29.1 mg/kg as a reference limit for the allowable content of benzoic acid in Douchi to determine whether benzoic acid additives were included during production.This study provides a scientific basis for setting a reasonable risk reference value for benzoic acid in Douchi,helping to avoid misjudgments caused by exceeding the baseline content.关键词
