摘要
本研究建立了高效液相色谱法测定水果中维生素C及有机酸含量的方法,研究了不同pH值条件下测定水果中维生素C及有机酸含量的变化情况,并分析了水果中有机酸含量与维生素C含量的关系。结果表明,在pH 2.5时,水果中维生素C和有机酸含量均为最高,有机酸含量与维生素C含量不成正比关系。
This study established a high performance liquid chromatography method for the determination of vitamin C and organic acid content in fruits,studied the changes in the determination of vitamin C and organic acid content in fruits under different pH values,and analyzed the relationship between the organic acid content and vitamin C content in fruits.The results showed that at pH 2.5,the contents of vitamin C and organic acids in fruits were the highest,and the organic acid content was not proportional to the vitamin C content.
