不同产区红枣天然苯甲酸含量调查与分析
Investigation and Analysis of Natural Benzoic Acid Content of Jujube in Different Production Areas
摘要
Abstract
[Objective] In order to find out the distribution and source of natural benzoic acid in jujube.[Method] High performance liquid chromatography (HPLC) was used to detect and analyze benzoic acid in 122 batches of dry red dates harvested from three major producing areas of China and at the same time,the change of benzoic acid during the fruit development and storage period was studied.[Result] The content of benzoic acid in jujube fruit calculated by dry basis is generally lower than 150 mg/kg,and the overall distribution in the range of 40-50 mg/kg is more concentrated.The contents of benzoic acid in different varieties were different,and the jujube and Zanhuang jujube were significantly higher than other varieties.Jun-jujube fruit ripening process continued accumulation of benzoic acid,reaching its peak in the end stage.The content of benzoic acid in the storage process varied with the initial content,and the storage process with higher initial content varied greatly.[Conclusion] The distribution range of natural benzoic acid in jujube fruit was preliminarily elucidated.The results have provided an important basis for the formulation or revision of the standard of benzoic acid content in jujube.关键词
