Title: Determination of Organic Acids in Vinegar and Difference Analysis
Abstract: To establish a method for determination of eight organic acids in vinegar by high-performance liquid chromatography(HPLC).Eight kinds of organic acid showed a good linearily in the testing concentration range.The correlation coefficients of the constitutes were higher than 0.9997,the recoveries were 83.47-101.29%,and the RSD were 1.47-6.48%.The contents of organic acids in vinegar samples obtained from different areas and production process were analyzed.The results showed that the composition and content of organic acids in vinegar reflected the characteristic of the samples,and the content of organic acids in solid state fermentation vinegar is more than liquid fermentation vinegar.By measuring and analyzing the content of lactic acid and acetic acid in vinegar,fermented vinegar could be easily to differentiate from blend vinegar.
