Changes of Volatiles from Apple Fruits during Maturity and Storage

Abstract

|
|
The changes of the volatiles from apple fruits were examined with Mallus pumila Miller var. Fuji, Ralls Janet and Jonathan harvested at the preclimacteric stage and stored under the normal atmospheric pressure of 760mmHg and subatmospheric pressure of 380mmHg at the temperature of 1 and 20℃ each. The production of the volatites in the normal storage temperature increased markedly up to around 30 days on storage and then decreased rapidly, whereas that of the volatiles in the low storage temperature increased slowly before decreasing. The changing pattern of volatiles from apples during storage at the normal atmospheric pressure was more remarkable than that of volatiles produced at the subatmospheric pressure. During storage, most of flavoring materials were increased, and the decrease of the content of esters was more rapid than that of alcohols and aldehydes among the volatiles. The amounts of the volatiles in Fuji apples during ripening at 20℃ after removing from the subatmospheric pressure storage for 90 days at 1℃ were nearly maximum at 3 days on ripening.
