Edible and active coatings for fresh produce preservation
Innovative edible coatings composed of biopolymers and natural additives extend the shelf life of fresh fruits and vegetables by reducing dehydration and microbial spoilage. These solutions maintain produce quality by allowing optimal gas exchange and preventing spoilage.
Overview
Zasuna Solutions LLC introduces a groundbreaking approach to enhancing the shelf life of fresh fruits and vegetables through the use of edible and active coatings. These coatings are designed to reduce dehydration and microbial spoilage, thereby prolonging freshness without altering the produce's flavor, odor, texture, or color. The technology leverages a blend of biopolymers and natural additives with antimicrobial and antioxidant properties to ensure optimal preservation.
Technical specifications
The edible coatings are composed of biopolymers such as polysaccharides (e.g., starch, chitosan), proteins (e.g., whey, soy), and lipids (e.g., vegetable oils). These are combined with natural additives like essential oils that serve as plasticizers and antimicrobial agents. The formulations are tailored to different types of produce and preservation needs, utilizing solvents like ethanol and water to ensure uniform application. The coatings are designed for efficacy through controlled release or gradual phase separation of additives, with microencapsulation as a potential method to extend their effects.
Technology readiness level
Currently at Technology Readiness Level 2, this solution is in the concept and formulation stage. Future validation will involve testing various coating compositions for their effectiveness and adjusting formulations to meet specific preservation requirements for different types of produce.
