Optimal temperature and modified atmosphere for keeping quality of fresh-cut pineapples
نویسندگان
چکیده
The influences of storage temperature and modified O2 and CO2 concentrations in the atmosphere on the post-cutting life and quality of fresh-cut pineapple (Ananas comosus) were studied. Temperature was the main factor affecting post-cutting life, which ranged from 4 days at 10 ◦C to over 14 days at 2.2 and 0 ◦C. The end of post-cutting life was signaled by a sharp increase in CO2 production followed by an increase in ethylene production. The main effect of reduced (8 kPa or lower) O2 levels was better retention of the yellow color of the pulp p M p ©

متن کاملMaintaining optimal atmosphere conditions for fruits and vegetables throughout the postharvest handling chain
Optimal controlled and modified atmospheres (CA and MA) for fresh produce vary according to the specie, its maturity or ripeness stage, the temperature, and the duration of exposure. However, individual lots of produce are typically handled for different times and at different temperatures during storage, transportation, and retail display. In this paper, we review some of our previous work sho...
