Abstract

Abstract:

With ‘Red Delicious’apple as a material, the specific position of α-farnesene formation in the apple were identified，respectively，to provide experimental evidence for the proposal of the mechanism of apple superficial scald. Results showed that α-farnesene was formed in large amount in horny layer，and not only difused outward to wax layer but also inward to hypodermic and pulp cell． Once it met oxygen in horny and wax layer． α-farnesene was oxidized to conjugated trienes and other products．The degree of scald development and the both contents of α-farnesene and conjiugated trienes were inversely propotional to store temperature．

Key words: Apple, Superficial scald, α-farnesene, Conjugated trienes, Storage, Temperature
