Optimum postharvest storage conditions increase the postharvest quality and shelf life of horticultural crops. The effects of forced-air precooling (FAP) and modified atmosphere packaging (MAP) on shelf life, physicochemical quality, and health-promoting properties of bell pepper ( L. cv. Nagano) harvested at 90 and 50% coloring stages in May and July respectively, stored at 11 °C, 95% relative humidity were assessed. Fruits were subjected to four treatments: FAP + 30 μm polyethylene liner (FOLO); FAP-only (FOLX); 30 μm polyethylene liner-only (FXLO); and control (FXLX). The quality attributes, viz. weight loss, firmness, color, soluble solids content (SSC), soluble sugars, total phenolic content (TPC), total flavonoid content (TFC), 2,2-dephenyl-1-picrylhydrazyl (DPPH), and 2,2'-azino-bis-3-ethylbenzo-thiazoline-6-sulfonic acid (ABTS) were evaluated. The investigated parameters differed significantly ( < 0.05) among treatments except for soluble sugars. FOLO maintained sensory quality (weight loss, firmness, and color), physicochemical (SSC and soluble sugars), and health-promoting properties compared to other treatments during storage. The 50% coloring fruits had a huge variation between treatments than 90% coloring. The results revealed more TPC and antioxidant capacity in the 50% than in the 90% coloring fruits. The study highlights the need to consider the ideal fruit coloring stage at harvest under the effect of FAP and MAP treatments in preserving bell pepper's postharvest quality and shelf life.

This study investigates the effect of 100 mg L thymol treatment on the quality of post-harvest peppers stored at 10 °C. The results showed that thymol treatment significantly reduced decay rate, reactive oxygen species (ROS) accumulation, and saturated fatty acid levels in peppers. Moreover, unsaturated fatty acids, non-enzymatic antioxidants, and antioxidant enzyme levels increased after treatment.

Sugars act as signaling molecules to modulate various growth processes and enhance plant tolerance to various abiotic and biotic stresses. Moreover, sugars contribute to the postharvest flavor in fleshy fruit crops. To date, the regulation of sugar metabolism and its effect in plant growth, fruit ripening, postharvest quality, and stress resistance remains not fully understood.

Significant losses of vegetables and fruits occur at multiple stages, including harvest, sorting, storage, and transportation, primarily due to mechanical damage, pathogen invasion, and the natural process of senescence. To mitigate postharvest decay and maintain superior quality of produce, conventional techniques such as low temperature storage and synthetic fungicide treatment are widely employed. Acibenzolar-S-methyl (ASM), an effective plant resistance inducers, has demonstrated its efficacy in protecting against a diverse range of fungal and bacterial pathogens.

Understanding the global transcriptomic and metabolic changes during mulberry growth and development is essential for the enhancing fruit quality and optimizing breeding strategies. By integrating phenotypic, metabolomic, and transcriptomic data across 18 developmental and ripening stages of Da10 mulberry fruit, a global map of gene expression and metabolic changes was generated. Analysis revealed a gradual progression of morphological, metabolic, and transcriptional changes throughout the development and ripening phases.

The research intended to explore the control ability of alginate oligosaccharide (AOS) on Penicillium expansum infection in pear fruit by priming response and its mechanism. The results showed that 100 mg L AOS treatment could significantly reduce the incidence of postharvest blue mold and the lesion diameter in pear fruits and maintain their quality. The defense responses induced by AOS treatment alone were relatively mild in pear fruits.
