Hydrophobic antimicrobial protein coating for fresh berries
A natural, edible coating using whey protein and aloe vera, designed to extend berry shelf life by enhancing water repellency and antimicrobial properties. This innovative solution aims to replace synthetic pesticides with a fully food-based coating.
Overview
This innovative solution focuses on developing a natural, edible coating for fresh berries using food-derived materials such as whey protein and aloe vera. The coating is designed to extend the shelf life of berries by enhancing their water repellency and antimicrobial properties. This approach aims to replace synthetic pesticides with a fully food-based alternative, addressing the growing demand for sustainable and safe food preservation methods.
Technical specifications
Key components:
- Whey protein: Provides hydrophobic properties to repel water and prolong freshness.
- Aloe vera: Offers antimicrobial properties to protect against spoilage.
- Gums and other compounds: Ensures adhesion and enhances functionality.
Development process:
- Material extraction: Natural materials like mushroom fibers and whey proteins are extracted for their beneficial properties.
- Formulation selection: Various formulations are created to achieve optimal adhesion and functionality.
- Property testing: Coatings are assessed for hydrophobicity, moisture absorption, and antimicrobial activity on flat surfaces.
- Application on berries: The most effective formulations are applied to berries to test spoilage reduction and moisture retention.
Technology readiness level
Currently at TRL 4, this solution has undergone laboratory testing and demonstrates promise for further development and real-world applications. The next phases will involve refining formulations and conducting more extensive testing on berries to ensure efficacy and sustainability.
