Sensory quality performance of two nectarine flesh typologies exposed to distant market conditions
MetadataShow full item record
The objective of this research was to evaluate the shelf life of two nectarine flesh typologies in order to determine the exporting potential of fresh nectarines to distant markets. "Maria Dolce" (subacid fruit type) and "Venus" (normal fruit type) nectarines were harvested at two maturity stages, based on fruit ground color. Fruits were stored at 0C and 90% R.H. for 14 or 42 days, simulating storage duration aimed respectively to shipping to close or distant marketplaces. Nectarines were evaluated after a period of ripening at 20C, when flesh firmness reached 9.8-19.6 N. Visual appearance, color, aroma, flesh texture, sweetness, sourness, juiciness, flavor and acceptability were evaluated. Both varieties presented a better eating quality when harvest was delayed. "Maria Dolce" presented high storage ability, reaching even at 42 days the same acceptability of fruit not subjected to cold storage. "Venus" showed a significant decrease in acceptability, indicating a not sufficient tolerance to long storage.
