Abstract

Maintaining the quality of fresh-cut produce during transport is crucial in the rapidly expanding e-grocery market. The present study investigates how varying quantities of ice packs in delivery boxes affect the preservation of fresh-cut paprika (Capsicum annuum L.) under simulated high-temperature conditions. We monitored several key quality indicators—temperature profile, appearance, weight loss, color, firmness, microbial growth, antioxidant activity, and volatile metabolite profile—of fresh-cut paprika stored in expanded polystyrene (EPS) containers at 30 °C over 48 h. The results demonstrated that with no ice packs, internal temperatures rapidly reached the external temperature within 6 h, which rapidly degraded the quality. In contrast, using ice packs significantly decelerated temperature increases, with two ice packs exhibiting the least overall quality decline. These samples exhibited substantially lower weight loss (<10 %) than those devoid of ice packs (26.3 %), alongside better color and firmness retention, and microbial counts remaining below the safety threshold of 5 log CFU g⁻¹ for up to ¹2 h. Additionally, ice packs delayed changes in volatile metabolite profile, thereby preserving desirable flavors. This study provides empirical evidence of the effectiveness of ice packs in ensuring the safety and quality of fresh-cut paprika during deliveries, contributing insights into effective distribution strategies for perishable products.

期刊介绍： The journal is devoted exclusively to the publication of original papers, review articles and frontiers articles on biological and technological postharvest research. This includes the areas of postharvest storage, treatments and underpinning mechanisms, quality evaluation, packaging, handling and distribution of fresh horticultural crops including fruit, vegetables, flowers and nuts, but excluding grains, seeds and forages. Papers reporting novel insights from fundamental and interdisciplinary research will be particularly encouraged. These disciplines include systems biology, bioinformatics, entomology, plant physiology, plant pathology, (bio)chemistry, engineering, modelling, and technologies for nondestructive testing. Manuscripts on fresh food crops that will be further processed after postharvest storage, or on food processes beyond refrigeration, packaging and minimal processing will not be considered.
