The production of furan compounds may be related to the Maillard reaction;terpenoids are the important components of the typical fragrance of fruits and flowers, aldehydes usually endow daylilies with sweet, floral, and fruity fragrances;alkanes, as precursors, are often involved in the flavor variation of daylilies. Through the analysis of amino acid content, the amino acids in microwave-dried daylily products are mainly in free form, accounting for 91.96% of the total amino acid content, which better explains the origin of the delicious flavor of daylily products. The content of umami amino acids is significantly higher than that of the other three taste amino acids, with Glu, Asp, Gly and other umami amino acids accounting for a relatively high proportion, giving daylily fresh sweet and refreshing characteristics, has an important contribution to the flavor of daylily and has a special effect of forming the flavor of daylily and buffering acid and bitter taste.展开更多
