A method for detecting a plurality of fat-soluble nutrients in food and application thereof

Abstract

This invention provides a method for detecting multiple fat-soluble nutrients in food and its application, belonging to the field of food testing technology. The method includes: extracting a food sample via saponification, followed by extraction with a quaternary compound antioxidant extractant, purification with a purification material, concentrating and redissolving the supernatant to obtain the test solution; detecting the test solution using a two-dimensional liquid chromatography system; and calculating the content of multiple fat-soluble nutrients in the food based on the detection results. This method is applicable to both starch-containing and non-starch-containing foods, enabling simultaneous, rapid, and accurate detection of multiple fat-soluble nutrients in food. It provides a more efficient technical means for food quality control, assisting in food safety monitoring and nutritional evaluation; simultaneously, it provides a convenient testing solution for food production enterprises, promoting product quality improvement.
