“…Fruits are commonly harvested on the basis of conventional extrinsic factors such as firmness, color, size, and shape. More recently, intrinsic factors such as nutritional and functional attributes have been considered, including minerals, vitamins, dietary fibers, and other polyphenolic constituents that exhibit beneficial health properties [27]. During postharvest handling, transportation, and bulk storage, fruits may be highly susceptible to biological and/or mechanical hazards that can affect both intrinsic and extrinsic factors [28].…”

“…In addition to improper postharvest handling of fruits, mechanical vibrations may affect the fruit quality during transportation, triggering heavy losses during longer storage periods. The quality problems that emerge in metabolically active fruits during postharvest storage include physiological deterioration and microbial deterioration as evidenced by moisture loss, softening of flesh, ripening, and decay caused by pathogenic bacterial strains, molds, or yeast rots [27,29].…”

This review reports recently published research related to the application of polysaccharide-based biodegradable and edible coatings (BECs) fortified with bioactive compounds obtained from plant essential oils (EOs) and phenolic compounds of plant extracts. Combinations of polysaccharides such as starches, pectin, alginate, cellulose derivatives, and chitosan with active compounds obtained from clove, lemon, cinnamon, lavender, oregano, and peppermint have been documented as potential candidates for biologically active coating materials for retardation of quality changes in fresh fruits. Additionally, polysaccharide-based active coatings supplemented with plant extracts such as cashew leaves, pomegranate peel, red roselle, apple fiber, and green tea extracts rich in phenolic compounds and their derivatives have been reported to be excellent substituents to replace chemically formulated wax coatings. Moreover, EOs and plant polyphenolics including alcohols, aldehydes, ketones phenols, organic acids, terpenes, and esters contain hydroxyl functional groups that contribute bioactivity to BECs against oxidation and reduction of microbial load in fresh fruits. Therefore, BECs enriched with active compounds from EOs and plant extracts minimize physiological and microbial deterioration by reducing moisture loss, softening of flesh, ripening, and decay caused by pathogenic bacterial strains, mold, or yeast rots, respectively. As a result, shelf life of fresh fruits can be extended by employing active polysaccharide coatings supplemented with EOs and plant extracts prior to postharvest storage.

“…In this way, it can be aligned with SDG 2, which calls for an improved nutrition provision [80]. If more local food is consumed, this leads to more seasonal products in food supply, which can mean a greater nutritional value, due to less storage and optimized harvesting times [81][82][83]. Besides health, nutritional, and economic considerations, local food systems offer public benefits, such as the preservation of farmland in urbanizing areas, as well as the conservation of genetic diversity or the environment [39,84].…”

Measures to Increase Local Food Supply in the Context of European Framework Scenarios for the Agri-Food Sector

et al. 2021

The issue of local food supply has attracted considerable political and public attention, due to the changing preferences of consumers, who have more awareness about ecological sustainability, in particular, but also due to recent developments concerning the COVID-19 pandemic. In order to identify measures facilitating local food value chains, which are resilient to different nationwide and global future developments, the aim of our analysis was to set the identified measures derived from the local roadmap of the city of Graz in the context of European scenarios for the agri-food sector in 2035. The results show that certain measures are applicable under all of the described scenarios, such as the food policy council, whereas some measures—for example, open food labs—are less suitable or need to be adjusted to fit the purpose within changing framework conditions. Setting specific measures for a city region in the broader context of European agri-food scenarios provides a systemic perspective, thus making the multiple links and influences more visible.

“…Low temperature (LT) and controlled atmosphere (CA) conditions (low O 2 and elevated CO 2 ) are extensively employed to prolong the postharvest life of horticultural crops. However, horticultural crops may suffer from chilling injury and other physiological disorders, as well as excessive water loss and fungal decay (e.g., Lum et al, 2016b ; Tarkowski et al, 2020 ; Ziv and Fallik, 2021 ).…”

“…Fruits, vegetables and nuts are a crucial part of a healthy diet, which can help reduce risk factors for non-communicable diseases. Increasingly, consumers are concerned with the nutritional quality of these commodities ( Kyriacou and Rouphael, 2018 ; Ziv and Fallik, 2021 ). Postharvest deterioration can result in qualitative and quantitative changes in their marketability, as well as incredible economic losses to the horticultural industry.…”

γ-Aminobutyrate Improves the Postharvest Marketability of Horticultural Commodities: Advances and Prospects

2022

Postharvest deterioration can result in qualitative and quantitative changes in the marketability of horticultural commodities, as well as considerable economic loss to the industry. Low temperature and controlled atmosphere conditions (low O2 and elevated CO2) are extensively employed to prolong the postharvest life of these commodities. Nevertheless, they may suffer from chilling injury and other physiological disorders, as well as excessive water loss and bacterial/fungal decay. Research on the postharvest physiological, biochemical, and molecular responses of horticultural commodities indicates that low temperature/controlled atmosphere storage is associated with the promotion of γ-aminobutyrate (GABA) pathway activity, with or without the accumulation of GABA, delaying senescence, preserving quality and ameliorating chilling injury. Regardless of whether apple fruits are stored under low temperature/controlled atmosphere conditions or room temperature, elevated endogenous GABA or exogenous GABA maintains their quality by stimulating the activity of the GABA shunt (glutamate GABA succinic semialdehyde succinate) and the synthesis of malate, and delaying fruit ripening. This outcome is associated with changes in the genetic and biochemical regulation of key GABA pathway reactions. Flux estimates suggest that the GABA pool is derived primarily from glutamate, rather than polyamines, and that succinic semialdehyde is converted mainly to succinate, rather than γ-hydroxybutyrate. Exogenous GABA is a promising strategy for promoting the level of endogenous GABA and the activity of the GABA shunt in both intact and fresh-cut commodities, which increases carbon flux through respiratory pathways, restores or partially restores redox and energy levels, and improves postharvest marketability. The precise mechanisms whereby GABA interacts with other signaling molecules such as Ca2+, H2O2, polyamines, salicylic acid, nitric oxide and melatonin, or with phytohormones such as ethylene, abscisic acid and auxin remain unknown. The occurrence of the aluminum-activated malate transporter and the glutamate/aspartate/GABA exchanger in the tonoplast, respectively, offers prospects for reducing transpirational water in cut flowers and immature green fruit, and for altering the development, flavor and biotic resistance of apple fruits.
