Determination of Methanol and Ethanol in Soy Sauce by Headspace Gas Chromatography
Determination of Methanol and Ethanol in Soy Sauce by Headspace Gas Chromatography

Name: Packed column
Specification: 2m*3mm
Model: GDX-101. 60-80 mesh

Soy sauce is a condiment produced from raw materials such as soybeans and wheat through raw material cleaning, cooking, koji making, fermentation, sterilization, filling and other processes. It is extremely nutritious. The main nutrients include amino acids, soluble proteins, sugars, and acids. Wait. It is not only a necessary condiment for restaurants to make dishes, factories to make canned meat, and snack shops to prepare food, but it has also entered thousands of households. In the process of koji making and fermentation of soy sauce, yeast fermentation can produce alcohol, acid, aldehyde, ester, phenol, acetal and furanone and other components, which may contain a certain amount of methanol and ethanol.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. used GDX-102 headspace gas chromatography to determine the content of methanol and ethanol in soy sauce. The internal standard method was used to quantify the content and the results were satisfactory.
