Revolutionizing tropical fruits preservation: Emerging edible coating technologies

Area of Science:

• Food Science
• Materials Science
• Biotechnology

Background:

• Tropical fruits are highly perishable, leading to nearly 50% postharvest loss globally.
• Edible biopolymeric nanoparticles present a promising solution for preserving fruit freshness.
• These nanoparticles are safe, biodegradable, and possess antimicrobial and antioxidant properties.

Purpose of the Study:

• To review the application of edible biopolymeric nanoparticles in tropical fruit preservation.
• To assess their impact on physical, sensory, and microbial properties.
• To explore formulation, application, safety, and industrial perspectives.

Main Methods:

• Review of scientific literature on edible biopolymeric nanoparticles for fruit coatings.
• Analysis of ionic gelation as a preparation method.
• Evaluation of various application techniques (e.g., spraying, layer-by-layer).

Main Results:

• Biopolymeric nanoparticles can enhance physical and sensory attributes of tropical fruits.
• They effectively inhibit microbial growth and extend shelf life.
• Material selection and application methods are critical for efficacy.

Conclusions:

• Edible biopolymeric nanoparticles are a viable technology for reducing tropical fruit spoilage.
• Further research into safety, legislation, and industrial scalability is needed.
• This approach supports sustainable food systems and reduces food waste.
