Fish collagen and κ-carrageenan hydrogel for probiotics encapsulation
Innovative hydrogel using fish collagen and κ-carrageenan for microencapsulation of probiotics, enhancing cell viability and shelf life in low pH beverages. This anionic hydrogel maintains integrity in acidic media and releases probiotics in alkaline conditions.
Overview
This solution involves a novel hydrogel composed of fish collagen and κ-carrageenan designed for the encapsulation of probiotics. The combination of these materials results in a hydrogel with enhanced mechanical strength and stability, making it suitable for use in low pH beverages. The hydrogel's anionic properties allow it to remain intact in acidic environments, such as gastric acid, and to swell and dissociate in alkaline conditions like those found in the intestines. This behavior ensures effective release of encapsulated probiotics, potentially improving their viability and shelf life.
