1,2-Propanediol (1,2-propanediol) is an excellent solvent commonly used in edible flavors and fragrances in the food industry. It is also a food synthetic fragrance specified in the food additive standard. It is colorless and almost tasteless under normal conditions. Milk flavors and essences mostly use 1,2-propanediol as a carrier solvent. Using 1,2-propanediol in milk flavors and flavors as markers, the detection of markers in liquid milk indirectly reflects the addition of flavors. It is a simple and easy method to quickly screen illegally added flavors in liquid milk. .

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. used gas chromatography to determine 1,2-propanediol in food, and the area external standard method was used for quantification, and the results were accurate and reliable.
