Evaluation of a Packaging System in Pallets Under Modified Atmosphere to Extend the Shelf-life of ‘Padrón’ Peppers Stored at Refrigeration Temperature. Food Bioprocess Technol (2022). https://doi.org/10.1007/s11947-022-02966-21935-5130http://hdl.handle.net/10347/29996A modified atmosphere packaging (MAP) system in pallets was developed for ‘Padrón’ peppers as a way to extend their shelf-life while maintaining good fruit quality. Peppers were stored at 6 °C in cardboard boxes arranged on pallets wrapped in micro-perforated low-density polyethylene (LDPE) bags. Physico-chemical (moisture, firmness, color, chlorophylls, carotenoids, ascorbic acid, and total phenolic content) and sensory analysis were carried out after 0, 7, 14, and 21 days of storage. An initial mixture of 11.8% O2–8.5% CO2 prevented anaerobic conditions and kept suitable CO2 levels throughout the entire storage period. Silica gel was tested as a moisture absorbent and considerably reduced water vapor condensation inside packaging bags. The MAP system developed maintained the shelf-life of peppers until the end of the 21-day storage period. The fruit always showed a good appearance and color. No rotting or other types of undesirable alterations were observed. MAP markedly reduced the fraction of peppers with water loss as evidenced by a minimum percentage of fruit with wrinkles (12.5%) as compared to unpackaged samples (75%). Good pigment stability was also observedeng© 2022 The Authors.
