A method was established to analysis volatile components in pulp and peel of bananas based on cryogenic frozen liquid-liquid extraction/GC-MS combined with retention index.The volatile components in bananas were extracted by a cryogenic frozen liquid-liquid extraction pretreatment method.39 kinds of volatile components in banana pulp and 32 volatile components in banana peel were identified, respectively. The main ingredients were esters. However,there were differences in the types and relative contents of the volatile components between pulp and peel.The main components in banana pulp were propionic acid ethyl ester(11.88%),isoamyl acetate(9.45%),hexadecanoic acid(8.71%),isovaleric acid butyl ester(7.79%), secondary amyl acetate(5.29%),while the major components in banana peel were isoamyl butyrate(22.85%), hexadecanoic acid(15.91%), stearic acid(6.86%), 4-allyl-2,6-dimethoxy phenol(6.83%),linolenic acid(6.34%).There were 19 kinds of components in both banana pulp and banana peel,such as isoamyl alcohol,isobutyl acetate,butyric acid,acetic acid and isoamyl para amyl.
