Elucidating these underlying mechanisms might bring novel avenues for browning inhibition. To achieve this objective, GN and CX were stored at 25°C and 90 ± 5% relative humidity for 6 days, and then the biochemical changes were investigated.

Strawberry (Fragaria × ananassa Duch.) is a widely favored horticultural crop renowned for its unique taste and flavor. To develop an accurate predictive model for strawberry freshness, colorimetric data, total soluble solids, titratable acidity, and volatile organic compounds (VOCs) were investigated in fully ripe 'Jukhyang' and 'Merry Queen' strawberries. Data measurements were conducted after 0, 4, 8, and 12 days of cold storage (10 °C, 79% RH).

This study investigated the effect of melatonin (MT) on postharvest storage quality of passion fruit. Passion fruits were treated with four different concentrations of MT solutions (100, 200, 300 and 400 μmol/L) for 30 min and stored for 8 days.

Fruits flavor deterioration is extremely likely to occur during post-harvest storage, which not only damages quality but also seriously affects its market value. This work focuses on the study of fruits deterioration odorants during storage by describing their chemical compositions (i.e., alcohols, aldehydes, acids, and sulfur-containing compounds).

In this work, the MeJA-loaded gelatin/pullulan/chitosan composite biofilm was prepared to inhibit the chilling lignification of the loquat fruit during storage at 0 °C. The firmness and lignin content were decreased by 89 % and 81.77 % after MeJA-loaded biofilm treatment. Malondialdehyde (MDA) production was almost completely suppressed and chilling injury of loquat fruit was significantly reduced.

Granulation is a serious physiological disorder in citrus fruit, which impairs the fruit quality and causes economic losses to the citrus industry. ‘Harumi’ ((Citrus unshiu × C. sinensis) × C. reticulate), a mandarin-type variety, is prone to granulation, especially after long-term storage.

Light and temperature are key factors influencing the accumulation of anthocyanin in fruit crops. To assess the effects of fruit bagging during development and high post-ripening temperature on ‘Hongyang’ kiwifruit, we compared the pigmentation phenotypes and expression levels of anthocyanin-related genes between bagged and unbagged treatments, and between 25 °C and 37 °C postharvest storage temperatures.

Fresh grapes are characterized by a short shelf life and are often subjected to quality losses during post-harvest storage. The quality assessment of grapes using image analysis may be a useful approach using non-destructive methods. This study aimed to compare the effect of different storage methods on the grape image texture parameters of the fruit outer structure.

Litchi (Litchi chinensis Sonn.) is a tropical fruit originating from southern China that is currently cultivated in subtropical and tropical regions worldwide. Litchi anthracnose, caused by Colletotrichum fructicola, a dominant species of Colletotrichum spp., is an important disease of litchi that damages the fruits in fields and in post-harvest storage.

Traditional methods of preserving loquats are summarized. Nanotechnology can extend the shelf‐life of fruits and vegetables through antioxidant, antimicrobial and ethylene removal, thus promising to solve the drawbacks of traditional preservation methods and to have a positive effect on the improvement of loquat in terms of post‐harvest quality. Abstract The loquat fruit is liked by many people for its rich nutritional value.

Food safety and sustainability have recently emerged as the key drivers of fresh horticultural produce supply and consumption.

SUMMARY Horticultural plants contribute immensely to the quality of human's life. The rapid development of omics studies on horticultural plants has resulted in large volumes of valuable growth‐ and development‐related data. Genes that are essential for growth and development are highly conserved in evolution. Cross‐species data mining reduces the impact of species heterogeneity and has been extensively used for conserved gene identification.

Wild birds pose a difficult food safety risk to manage because they can avoid traditional wildlife mitigation strategies, such as fences. Birds often use agricultural fields and structures as foraging and nesting areas, which can lead to defecation on crops and subsequent transfer of foodborne pathogens.

Summary This study investigates the development of Poly‐vinyl alcohol (PVA) and essential oil‐based biocomposite films incorporating halloysite nanotubes (HNT) and cellulose nanocrystals (CNC) as reinforcement materials for the packaging of papaya fruits to extend their postharvest shelf‐life. The fabrication process involves the dispersion of filler materials within the PVA polymer matrix, followed by the casting of the films using the solvent‐evaporation technique.

Apple is classified as a climacteric fruit, characterized by a rapid surge in ethylene levels at the onset of ripening. However, there is significant variation in the degree and timing of ripening and softening among different apple cultivars. Understanding the molecular mechanisms underlying fruit softening and the associated changes in cell wall integrity is crucial for improving fruit quality and extending shelf life.

Organic acids and essential oils are commonly used in the poultry industry as antimicrobials and for their beneficial effects on gut health, growth performance, and meat quality. A common postharvest storage fungal colonist, Aspergillus flavus, contaminates corn, the primary component of poultry feed, with the highly detrimental mycotoxin, aflatoxin.

Table grapes are considered non-climacteric fruit, not showing a rapid increase in respiration rate and ethylene production during ripening. Previous research has suggested that abscisic acid (ABA) may have a more crucial role in grape postharvest behaviour. This study aimed to identify biomarkers of postharvest resilience and flavour life of imported table grapes.

Abstract The marine finfish and crustaceans contribute immensely to human nutrition. Harvesting marine food‐fish to meet the global demand has become a challenge due to reduction of the fishery areas and food safety hazards associated with increased pre‐harvest and post‐harvest contaminations. The causes of low fish availability and contaminations were reviewed following the published literature from 2000 to 2023.

Cold shock precooling with ice-water mixture (0 ± 2 °C) was innovatively utilized in this study to supposedly improve the postharvest quality of chili pepper fruit during storage at 10 ± 2 °C. The chili peppers were randomly exposed to four different treatment groups being without and with cold shock for 30 min, 60 min and 90 min.

Pear (Pyrus L.) is one of the most important fruits in the world. Fruit dots are an important trait that affects pear quality. Abnormal fruit dots usually reduce the merchantability of pears. In this research, during cold storage, ‘Danxiahong’ pear fruit exhibited protrudent fruit dots on the peels. Microscopy system measurement showed that fruit dots size and height on the abnormal fruit peel were bigger and higher than the normal ones.

Demand for fresh vegetables has led to development studies in postharvest area mainly focused on minimizing and look for alternatives to chemical additives for food preservation. The use of natural derived edible coatings emerges as a promising alternative for maintaining quality of vegetables. The objective of this study was to evaluate the effect of Aloe vera gel in minimally processed carrot during postharvest storage.
