AI Technical Summary

Technical Problem

Existing packaging materials incorporating essential oils face challenges such as high volatilization rates, thermal instability, and inability to dilute in water, leading to reduced durability and potential organoleptic modification of food products, due to the volatility and immiscibility of these oils with water and polymers.

Method used

The development of functional clays with encapsulated essential oils and solid organic acids, where the oils are deposited on the surface of nanoclay particles, enhancing thermal stability and allowing for controlled release, thereby preventing evaporation and migration into food products.

Benefits of technology

This approach results in a stable and effective antimicrobial packaging that maintains the integrity of the packaging material and prevents organoleptic changes in food, ensuring prolonged effectiveness and safety for use in food preservation.
