Changes of some odor-active volatiles in low-ethylene controlled atmosphere stored apples.
Lebensm. Wiss. Technol. 24(2): 145-51.
The effect of low-ethylene controlled atm. storage (LCA) on the prodn. of 22 odor-active volatiles in McIntosh and Cortland apples was investigated. Aldehydes and acetates were not affected, while butanoates, 2-methylbutanoates, pentanoates and hexanoates were either severely or completely suppressed under LCA storage. However, most volatiles were produced normally during ripening of the fruit after LCA storage. Although several volatiles were produced at a lower rate during ripening of the fruit in air after LCA than during ripening immediately after harvest, this cannot be attributed entirely to the action of LCA. Volatiles that were suppressed by the action of LCA (3% O2 + 3% CO2 + 94% N2 at 3.3.degree., 1-6 ppm ethylene, for up to 8 mo) are Me butanoate, Pr butanoate, Bu 2-methylbutanoate, hexyl 2-methylbutanoate, Bu hexanoate and hexyl hexanoate.
