Developing canning peach critical bruising thresholds

摘要

The position of the softest spot on the fruit was the shoulder for 'Andross', 'Carson', 'Starn' and 'Ross' canning peach cultivars. Critical bruising thresholds were similar among canning peach cultivars evaluated, ranging from 6.0-7.0 lbf at a bruising potential of 240 G. Potential sources of bruising damage using two different mechanized harvesters were located using an instrumental sphere (IS-100). Bruising potential values of each harvester were small and similar, except at the bin dump portions of each machine.
