Lactose-based hydrogels for scalable food and cosmetic applications
Innovative lactose-based hydrogels using whey permeate offer sustainable solutions for food texture and cosmetic moisturization. Utilizing scalable processes, these hydrogels leverage dairy-derived carbohydrates' biocompatibility and functional properties.
Overview
Lactose-based hydrogels represent a sustainable innovation for enhancing food textures and cosmetic moisturizing systems. Utilizing whey permeate, a rich yet underutilized source of lactose, this technology transforms dairy by-products into high-value materials. By focusing on the inherent biocompatibility and functional properties of dairy-derived carbohydrates, these hydrogels cater to the growing demand for eco-friendly and effective solutions in both food and cosmetic industries.
Technical specifications
Key features:
- Utilizes lactose-induced Maillard crosslinking and fermentation-driven electrostatic gelation processes
- Derived from abundant dairy by-products like whey permeate
- Offers scalable production methods to achieve high-volume output
- Designed for applications in food texture modification and cosmetic product formulations
Development pathways:
- Maillard reaction-induced crosslinking of whey protein with lactose
