Advances in biosynthetic pathway and key regulatory factors of volatile esters in melon
Fruit aroma is an essential trait to evaluate the flavor quality of melon,it is also a key attribute of driving consumers'de-sire to buy.Complex and diverse aroma components constitute the melon aroma system,and characteristic aroma is the key component in the melon aroma system.The main aroma components of different varieties of melon were briefly described.The characteristic aromas of most melons were found,including ethyl acetate,phenyl methyl acetate,acetic acid-2-methyl-1-butyl ester,etc.Taking the characteristic aroma substances as an example,the synthetic pathway of characteristic aroma was analyzed and summarized.The key regulatory factors in esters synthesis were summarized,and future research on melon aroma quality was also prospected.The aim is to provide a theoretical ba-sis for the study of the mechanism of melon aroma formation.
