Abstract Blackberries and raspberries, commonly known as Rubus berries, are commercially grown worldwide across different climates. Rubus berries contain wide array of phytochemicals, vitamins, dietary fibers, minerals, and unsaturated fatty acids. Nevertheless, these berries have short storage life which is the major constraint in their supply chains leading to higher postharvest losses.

Abstract BACKGROUND Non‐fried shiitake mushroom (Lentinula edodes) crisps fabricated by explosion puffing drying (EPD) are receiving worldwide attention due to its crispness, convenience, nutrition and health functions. The quality of mushroom crisps varies with storage time of fresh L. edodes. Therefore, the effect of postharvest storage time (ranging 0 – 14 d) of fresh L. edodes on quality characteristics of EPD processed mushroom crisps were evaluated.

Environmental quality and food safety is threatened by contamination of lead (Pb) and cadmium (Cd) heavy metals in agricultural soils. Therefore, it is necessary to develop effective techniques for remediation of such soils. In this study, we prepared iron-modified biochar (Fe-BC) which combines the unique characteristics of pristine biochar (BC) and iron.

Novel modified atmosphere packaging (MAP) formulation maintains the qualities of strawberries. Abstract For fresh foods, the purpose and benefits of modified atmosphere packaging (MAP) generally include the preservation of antioxidants, the extension of shelf life, deferral of microbial spoilage, and retention of product color.

Abstract Background In an environment where the adoption of improved varieties resulting from plant breeding programs is limited, it is essential to identify end‐user preferences beforehand. A participatory survey was conducted in eight localities in Korhogo and Bouake regions, (central and northern Cote d'Ivoire, respectively) to identify producers' preferences and increase the adoption of improved varieties.

Fatty acid amides of palmitic (PAPY), lauric (LAPY), myristic (MYPY), and decanoic (DEPY) acids inhibited bacteria. Significant inhibition of Listeria and other bacteria increased at higher amide concentrations (10,000–20,000 ppm). LAPY reduced Listeria growth by 1.55 to >5.0 Logs in co‐inoculation assays and by 0.51 to >3.00 Log CFU/g on produce. Abstract Foodborne pathogens are a persistent threat to food and consumer safety.

Abstract This literature survey reveals the extended shelf life of foods when subjected to isochoric freeze processing. All other preservation aspects, thermal or non‐thermal, contribute to food preservation as per their specific functionality. From the given set of available food preservation technologies, shelf life extension by way of isochoric freezing works very well to extend the shelf life of fresh agricultural produce, without any weight loss and browning reaction to occur.

To preserve quality features and ensuring availability of fresh fruit on the market, apples need to be stored after harvest. The low temperature applied during storage, beside avoiding important fruit loss, can also promote the development of serious chilling injury disorders, such as superficial scald. One of the strategies largely employed to prevent the development of this phenomenon is the control of the storage atmosphere by lowering down the oxygen concentration.

Postharvest losses related to dry rot can reach 60% during long-term storage of potato tubers.

Peel browning is a natural phenomenon that adversely affects the appearance of fruits. Research on the regulation of browning in apples (Malus × domestica Borkh.) has mainly focused on postharvest storage, while studies at the preharvest stage are relatively rare. Apple is an economically important horticultural crop prone to peel browning during growth, especially when the fruits are bagged (dark conditions).

Growing tomato in hot weather conditions is challenging for fruit production and yield. Tomato cv. Savior is a heat-tolerant cultivar which can be grown during both the Vietnamese winter (mild condition) and summer (hot condition) season. Understanding the mechanisms of ethylene biosynthesis and signaling are important for agriculture, as manipulation of these pathways can lead to improvements in crop yield, stress tolerance, and fruit ripening.

Since the early characterization of vitamin C (ascorbic acid, AsA) as a major antioxidant molecule that human beings are unable to synthesize de novo, the discovery of adequate natural sources of AsA, as well as its elevation and preservation in fruit and vegetables through the entire food chain, has become a cutting-edge research topic in plant science as well as in 

Ensuring a safe and adequate food supply is a cornerstone of human health and food security. However, a significant portion of the food produced for human consumption is wasted annually on a global scale. Reducing harvest and postharvest food waste, waste during food processing, as well as food waste at the consumer level, have been key objectives of improving and maintaining sustainability.

Rapid postharvest quality deterioration of button mushroom as fruit body surface browning brings about senescence development and limits its distribution potential and postharvest storage. In this investigation, 0.5 mM of NaHS as the optimum concentration for H2S fumigation was applied to retain the quality of Agaricus bisporus mushrooms concerning some qualitative and biochemical attributes evaluation throughout 15 storage-day at 4°C and 80–90% relative humidity.

Botrytis cinerea is the causative agent of gray mold disease, and infects more than 1400 plant species, including important crop plants. In tomato, B. cinerea causes severe damage in greenhouses and post-harvest storage and transport. Plant viruses of the Tobamovirus genus cause significant damage to various crop species. In recent years, the tobamovirus tomato brown rugose fruit virus (ToBRFV) has significantly affected the global tomato industry.

Fungal spoilage of postharvest grains poses serious problems with respect to food safety, human health, and the economic value of grains. The protection of cereal grains from deleterious fungi is a critical aim in postharvest grain management. Considering the bulk volume of grain piles in warehouses or bins and food safety, fumigation with natural gaseous fungicides is a promising strategy to control fungal contamination on postharvest grains.

Introduction Lignification of fruit flesh is a common physiological disorder that occurs during post-harvest storage, resulting in the deterioration of fruit quality. Lignin deposition in loquat fruit flesh occurs due to chilling injury or senescence, at temperatures around 0°C or 20°C, respectively.
