Summary
This study developed an erasable metal-organic framework (MOF) coating to reduce postharvest losses in fruits. The coating combats pathogens and manages ethylene, extending shelf life sustainably.
Area of Science:
- Materials Science
- Agricultural Science
- Food Science
Background:
- Postharvest losses in fruits and vegetables are a significant global challenge.
- Effective strategies are needed to reduce spoilage and extend shelf life.
Purpose of the Study:
- To develop a novel, erasable metal-organic framework (MOF)-based coating for dual functionality in food preservation.
- To combat foodborne pathogens and manage ethylene levels in fruits.
Main Methods:
- A MOF-stabilized Pickering emulsion was used to create a uniform, erasable coating via dip-coating.
- Antimicrobial activity, ethylene scavenging capacity, and weight loss reduction were evaluated.
- Metabolomics and safety assessments were conducted.
Main Results:
- The coating showed broad-spectrum antimicrobial activity against tested fungi and bacteria.
- It significantly reduced fruit weight loss (19.7%) and captured ethylene production (72.3%).
- Metabolomics indicated downregulation of ripening-associated pathways, and safety assessments confirmed residue-free washability.
Conclusions:
- The developed MOF coating offers a sustainable solution for prolonging fruit shelf life.
- It effectively mitigates postharvest losses by controlling microbial growth and ethylene levels.
- The erasable and residue-free nature makes it a promising technology for the food industry.

21.9K
Fruits form from a mature flower ovary. As seeds develop from the ovules contained within, the ovary wall undergoes a series of complex changes to form fruit. In some fruits, such as soybeans, the ovary wall dries; in other fruits, such as grapes, it remains fleshy. In some cases, organs other than the ovary contribute to fruit formation; such fruits are called accessory fruits.

Microorganisms play a crucial role in agriculture and the food industry, contributing to soil fertility, crop protection, and food production. Their functions range from nitrogen fixation and biopesticide production to fermentation and food preservation, making them indispensable to sustainable farming and food safety.Role in AgricultureNitrogen-fixing bacteria, such as Rhizobium (symbiotic) and Azotobacter (free-living), convert atmospheric nitrogen into ammonia through biological nitrogen...

Biodeterioration refers to the unwanted alteration of materials caused by microorganisms—especially fungi—which damage both organic substrates (paper, wood, textiles) and inorganic ones (stone, plaster, glass). Unlike abiotic decay, biodeterioration results from biological activity that produces physical disruption and chemical degradation.Physical deterioration occurs as fungal hyphae penetrate pores, cracks, and surface irregularities. Hyphal turgor pressure, thigmotropic growth...

01:23Microbial Spoilage of Food
218
Microbial food spoilage refers to the degradation of food quality resulting from the metabolic activity of microorganisms such as bacteria, yeasts, and molds. These microbes proliferate on various food substrates depending on factors such as moisture content, nutrient availability, and storage conditions, leading to undesirable sensory and structural changes.Bacteria are primary agents of spoilage in high-moisture, nutrient-dense foods like meat, milk, and vegetables. Microbial spoilage occurs...

Lactic acid, an important organic acid extensively applied in food, pharmaceutical, and biodegradable polymer industries, is primarily produced via microbial fermentation. This method is favored over chemical synthesis due to its environmental sustainability and capacity for enantiomerically pure product formation. Among various microbial processes, the fermentation of starch-based substrates stands out due to the abundance and renewability of raw materials like corn and potatoes.Hydrolysis of...

Bioplastics derived from microbial processes present a sustainable alternative to conventional petroleum-based plastics. Among these, polyhydroxyalkanoates (PHAs), particularly polyhydroxybutyrates (PHBs), have emerged as prominent candidates due to their biodegradability and biocompatibility. These polymers are synthesized by a variety of bacteria, such as Cupriavidus necator and Pseudomonas putida, which naturally accumulate PHAs as intracellular carbon and energy reserves, especially under...
