摘要:2-Methylbutanoate Esters,Especially Ethyl 2-Methylbutanoate,Are Key Contributors To Fruit Aroma. The Biosynthetic Origins And Interconversions Of 2-Methylbutyl And 2-Methylbutanoate Esters In Red Delicious And Granny Smith Apples Were Determined By Feeding Deuterium-Labeled Substrates With Gc-Ms Identification Of The Deuterated Aroma Volatiles Produced. Deuterium-Labeled Isoleucine Was Fed To Apple Peel,And 2-Methylbutanoic-D(3) Acid,2-Methylbutanol-D(3),And Ethyl 2-Methylbutanoate-D(3) Were Fed As Vapor To Whole Apples. An Array Of Labeled 2-Methylbutyl And 2-Methylbutanoate Esters Was Produced From Each Substrate With Significant Differences In Products And Product Distributions Between The Two Apple Cultivars. Novel 2-Methyl-(2E)-Butenyl Esters Were Identified As Biosynthetic Products In The Aroma Of Red Delicious But Not Granny Smith Apples.
