Abstract

Excerpts from the report: Light transmission is an established nondestructive technique for evaluating the internal quality of many horticultural products. Although an apple transmits less than 0.1 percent of the light falling on it, the characteristics of this transmitted light have been related to quality and maturity. The objectives of this research were to (1) search for wavelength pairs that might be more closely related to apple quality than ΔOD (695-740 nm.), (2) evaluate light transmission as a quality-sorting technique for Red Delicious apples, and (3) compare controlled atmosphere (CA) and conventionally stored apples that had been previously sorted by light transmission.
