酱油是以大豆、小麦等原料,经过原料清洗、蒸煮、制曲、发酵、杀菌、灌装等工艺生产出来的调味品,营养极其丰富,主要营养成分包括氨基酸、可溶性蛋白质、糖类、酸类等。它不仅是餐馆制作菜肴、工厂制作肉类罐头、小食店配制食品所必需的佐料,而且已进入千家万户。在酱油的制曲及发酵过程中,酵母菌发酵能产生醇、酸、醛、酯、酚、缩醛和呋喃酮等多种成分,其中就可能含有一定量的甲醇和乙醇。

浩瀚色谱（山东）应用技术开发有限公司，采用GDX-102顶空气相色谱法测定酱油甲醇和乙醇含量,内标法定量，结果满意。

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.
