Quality of fresh-market melting- and nonmelting-flesh peach genotypes as affected by postharvest chilling.

After storage for 3 wk at 4 degrees C and ripening 3 days at 20 degrees C, nonmelting-flesh peaches ('Oro A', FL 90-35C, FL 90-47C) did not develop visual symptoms of mealiness, while melting-flesh (MF) fruit (FL 90-20, FL 90-21, FL 91-16) did. Sensory evaluation showed that only MF fruit were more "mealy" and less "sweet" and "peachy" as a result of chilling. Volatile analysis revealed that chilling caused increases in (E)-2-hexenal and decreases in gamma- and delta-decalactones in both MF and NMF types. However, the decline was considerably less in NMF than in MF fruit. Results indicate that chilling affects the quality of MF more than NMF genotypes.
