The amino acid profile of fresh products can indicate their nutritional value and flavor characteristics, therefore, many breeding projects around the world focus on these traits. Study the free amino acid content of fresh agricultural products and understand their impact on flavor and human health. In this application article, a simple LC/MS/MS method for analyzing the content of free amino acids in fresh agricultural products is described in detail. The sample preparation process of this method is simple, and free amino acids can be directly analyzed by injection without the need for derivatization.
