Analysis of Benzoic Acid, Sorbic Acid and Dehydroacetic Acid

By Keisuke Watanabe

PDF IconDownload This Application

January 5, 2024

Introduction

Among the food additives, there are several food preservatives. While many of them are toxic, they have a function to inhibit proliferation of various micro organisms which cause food to rot. Accordingly, the usage of such preservatives is limited and the target foods are regulated by the Food Sanitation Law.

This report describes the analysis of three kinds of food preservatives, Benzoic Acid, Sorbic Acid and Dehydroacetic Acid, according to the testing method for food additives described in the Standard methods of Analysis for Hygienic Chemistry.
