Abstract The effect of oxygen permeability of packaging material on shelf life of minimally processed and passive modified atmosphere packaged pomegranate arils, cv “Wonderful” as well as some quality attributes were investigated. Packaging materials having Oxygen transmission rate (OTR) as low as 125–290 cm3/m2/day were found to provide the gas concentration requirements of 2–5% O2 and 3–10% CO2 for passive modified atmosphere application of fresh fruits and vegetables.

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.

Abstract Fresh‐cut fruits and vegetables are still an active area of study despite being a staple of food outlets offering minimally processed foods. These minimally processed foods often have a short shelf life due to enzymatic browning. Active packaging is of current interest as it offers an efficient method to deliver polyphenol oxidase inhibitors onto the surface of foods to suppress browning.

A surplus of unused parts of vegetables (e.g., white cabbage cores and outer leaves) is generated daily by factories of fresh‐cut vegetables. Anaerobic fermentation of these vegetable residues with protease (Sumizyme FP) and Pediococcus pentosaceus did not produced l‐ornithine, however, when eggshell was added to them, large amounts of l‐ornithine were stably produced. These fermented products are sustainable food ingredients with the potential health benefits of l‐ornithine.

This study aims to describe the metabolic effects of seasonal consumption of red grapes as a rich and natural source of (poly)phenols. Specifically, it focuses on energy metabolism and the biology of the adipose tissue, a key player in the energy balance regulation in mammals. Moreover, it highlights that differences in (poly)phenol composition in one same fruit, resulting from distinct growing conditions, can also affect metabolism.

A visual summary of the findings. Summary Food safety is a crucial aspect of human well‐being, covered under the second sustainable development goal (SDG). Sustainable food supply chains must ensure compliance with food safety standards from farm to fork. Consumers in developed countries are becoming ever more demanding regarding ‘producers’ compliance with food safety and quality standards.

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.

The Arcobacter genus comprises a group of bacteria widely distributed in different habitats that can be spread throughout the food chain. Fluoroquinolones and aminoglycosides represent the most common antimicrobial agents used for the treatment of Arcobacter infections. However, the increasing trend of the antimicrobial resistance of this pathogen leads to treatment failures.

Giardia duodenalis and Enterocytozoon bieneusi are etiological agents of enteric diseases characterized by diarrhea that can progress to chronicity in humans, especially in children and in immunocompromised patients. This study aims to assess the genetic pattern of G. duodenalis and E. bieneusi detected in vegetables and fruits commercialized in Maputo markets, Mozambique and determine their public health importance.

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

The effects of farm management practices and seasonal variation on the microbial community and chemical composition of corn and grass-legume silage are largely understudied due to the advantages of controlled mini-silo experiments. This study aims to investigate the effects that some key farm factors (use of an inoculant, farm region, and bunker or tower silo) and seasonal variations have on corn and grass-legume silage from farms across Ontario, Quebec, and New York.

Porous organic polymers (POPs) are a class of materials that combine the properties of both polymers and porosity. They are characterized by their network structure composed of repeating organic units, which form pores or cavities throughout the material. Owing to their unique features including tunable porosity, abundant accessible active sites and synthetically control ability, POPs have been widely employed in the fields of catalysis, adsorption, and biomedicine.

Comprehensive Reviews in Food Science and Food Safety, EarlyView. Recently, multiple reports from regulatory agencies have linked leafy green outbreaks to nearby or adjacent cattle operations. While they have made logical explanations for this phenomenon, the reports and data should be summarized to determine if the association was based on empirical data, epidemiological association, or speculation.

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).

ETHYLENE-INSENSITIVE 3/ETHYLENE-INSENSITIVE 3-LIKEs (EIN3/EILs) are important ethylene response factors during fruit ripening. Here, we discovered that EIL2 controls carotenoid metabolism and ascorbic acid (AsA) biosynthesis in tomato (Solanum lycopersicum). In contrast to the red fruits presented in the wild type (WT) 45 d after pollination, the fruits of CRISPR/Cas9 eil2 mutants and SlEIL2 RNA interference lines (ERIs) showed yellow or orange fruits.

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.

Drought-induced protein 19 (Di19) is a drought-induced protein that is mainly involved in multiple stress responses. Here, three Di19-4 genes (MiDi19-4A/B/C) in mango (Mangifera indica L.) were identified, and the coding sequences (CDS) had lengths of 684, 666, and 672 bp and encoded proteins with 228, 222, and 224 amino acids, respectively.

Introduction Insect pests from the family Papilionidae (IPPs) are a seasonal threat to citrus orchards, causing damage to young leaves, affecting canopy formation and fruiting. Existing pest detection models used by orchard plant protection equipment lack a balance between inference speed and accuracy. Methods To address this issue, we propose an adaptive spatial feature fusion and lightweight detection model for IPPs, called ASFL-YOLOX.

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.

Soybean (Glycine max) is a major grain and oil crop worldwide, but low phosphorus (LP) in soil severely limits the development of soybean production. Dissecting the regulatory mechanism of the phosphorus (P) response is crucial for improving the P use efficiency of soybean. Here, we identified a transcription factor, GmERF1 (ethylene response factor 1), that is mainly expressed in soybean root and localized in the nucleus.

The role of Proteus mirabilis on food safety has not been investigated before. Three P. mirabilis strains (swupm1, swupm2 and swupm3) isolated from fresh-cut fruits were shown to vary in swarming motility, with strains swupm1 and swupm2, but not awupm3 exhibiting the characteristic bull's-eye phenotype. Strains swupm1 and swupm2 grew faster and produced stronger biofilm than swupm3.

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.
