Abstract

The effect of temperatures on the rate of O2 uptake (RRO2) and CO2 production (RRCO2) the Q10 and activation energy (Ea) of respiration the respiratory quotient (RQ) the rate of ethylene production the colour and visual quality attributes of ackee (Blighia sapida Kenig) fruit arils cheese� variety were measured. RRO2 averaged 0.26 0.63 and 0.96 mmol kg-1 h-1 and RRCO2 averaged 0.22 0.55 0.90 mmol kg-1 h-1 and ethylene production averaged 47.5 50.2 and 51.9 nmol kg-1 h-1 at 5 15 and 25C respectively. Neither RRO2 nor RRCO2 correlated with ethylene production. The RQ of arils varied from 0.89 to 1.0 and the Q10 varied from 1.8 to 2.0 while the Ea ranged from 40.4 to 51.6 kJ mole-1. Decay and quality loss were rapid at temperatures above 15C. When kept under chilling temperature (3C for 20 days with or without subsequent removal to 25C) ackee arils showed severe chilling injury symptoms. Decay was also accelerated by the removal to 25C. Collectively the data indicate that ackee fruit aril storage is limited to temperatures between 5C and 15C.
