Special Issue Information

Dear Colleagues,

Edible coatings are made from natural, biodegradable materials that can be safely consumed. These substances include a variety of proteins, polysaccharides, lipids, and composite materials, each offering unique protective properties to the produce they envelop. When applied to fruits and vegetables, these coatings form a thin, imperceptible layer that acts as a barrier to moisture, atmosphere gases, and microbial growth, factors that contribute to deterioration and spoilage. The result significantly extends the product's freshness, texture, and nutritional value.

However, the benefits of edible coatings go beyond just prolonging shelf life. They play a crucial role in reducing the dependence on synthetic packaging materials, particularly plastics, which are a major environmental concern. These coatings align with the increasing consumer demand for eco-friendly and sustainable food practices by providing a natural alternative. They also offer potential cost savings for producers and consumers, as the extended shelf life reduces food waste and loss.

This special topic aims to delve deeper into the scientific principles behind edible coatings, exploring their composition, the various types of coatings available, their application methods, and their effectiveness. It also examines this technology's environmental and economic implications and how it fits into the broader context of global food sustainability efforts. As we explore the potential of edible coatings, we stand on the brink of a paradigm shift in how we preserve, transport, and consume our fruits and vegetables, paving the way for a more sustainable and efficient food system.

Exploring the green and affordable protection of perishable cherry tomato fruits during storage, herein, the protective efficacy, and its underpinning mechanisms, of a coating of oleaster gum, alone or incorporated with cuminal, on cherry tomatoes stored at ambient temperature was investigated. The composite coating of oleaster gum with 0.1% cuminal reduced the decay, respiration rate, weight loss, and softening of the fruits and decelerated the decreases in their total soluble solid, titratable acidity, and soluble protein levels, and therefore maintained their marketability. Furthermore, it reduced the accumulation of O2· and H2O2 in the fruits and mitigated cell membrane lipid oxidation and permeabilization, thereby retarding their senescence. Instrumentally, it elevated the activities of superoxide dismutase, catalase, peroxidase, and ascorbate peroxidase and the levels of ascorbic acid and glutathione. This potentiation of the fruits’ antioxidant system makes this composite coating a promising approach to keeping the postharvest quality of perishable fruits. Full article
