ABSTRACT

Marketing of raspberries is limited by their short postharvest life under refrigerated storage (<14 days). Short-term controlled atmospheres have been found to be effective in increasing the storage life of different crops and providing a more sustainable alternative to maintain postharvest quality compared to a continuous controlled atmosphere (CA). In this work, the effect of short-term CA treatments: early (15% CO₂, 10% O₂ for 3 days + air for 11 days) and intermediate (3 days in air +3 days 15% CO₂, 10% O₂ + 8 days in air) versus continuous CA on the postharvest quality of red raspberry cv. “Adelita” was evaluated. Short-term CA treatments significantly reduced weight loss during the first 6 days of storage. Early CA fruit showed longer sensory shelf life (SSL) values, and improved color parameters during storage compared to control.

摘要

覆盆子的行销受到其在冷藏条件下（<14天）的较短的收获后寿命的限制。与连续控制气氛（CA）相比，发现短期控制气氛可有效延长不同农作物的贮藏寿命，并为维持采后质量提供更可持续的选择。在这项工作中，短期治疗CA的效果：早期（15％CO ₂，10％氧气₂ 3天+空气11天）和中间体（3天在空气3天15％CO ₂，10％ Ø ₂ 空气中+ 8天）与连续覆膜对红树莓简历收获后品质的影响。对“ Adelita”进行了评估。短期CA治疗可在储存的前6天显着减少体重减轻。与对照相比，早期的CA果实显示出更长的感官保存期限（SSL）值，并且在存储过程中改善了颜色参数。
