ABSTRACT
BACKGROUND:
Current consumer demand for high-quality ready-to-eat fresh fruit in convenient bio-based packaging was met utilizing sanitized stem-free sweet cherries and a polylactic acid (PLA) cup with a PLA peelable microperforated lid. The newly developed packaging system was compared with the petroleum-based macroperforated bag currently used for retail.RESULTS:
After 27 days of storage at 1 °C, the PLA package maintained the cherry firmness, compared with a 50% reduction of the controls. No fungal decay was detected in the cherries stored in PLA, while the controls were non-marketable after 21 days. The PLA package allowed minimal weight loss (0.8%), compared with a weight loss of approximately 16% in the controls. Differences in the cherry aroma, color, acidity, soluble solids content, pH and quality index were also caused by the packaging type. A consumer sensory evaluation showed that cherries stored in PLA packages were more acceptable than those of the controls for appearance, texture, flavor and overall acceptability.CONCLUSION:
The new package matched both the consumer demand for high-quality fresh fruit ready for consumption in convenient bio-based packaging and the extended fruit marketability and consumer satisfaction desired by industry.Palabras clave
