Immobilized enzymes for controlled psyllium depolymerization
This innovative solution utilizes immobilized carbohydrase enzymes to achieve controlled depolymerization of psyllium arabinoxylan. By reducing molecular weight, it decreases hydration rate and gel strength while preserving psyllium's functional benefits, enhancing consumer acceptance.
Overview
Immobilized enzymes for controlled psyllium depolymerization offer a novel approach to modify psyllium fiber properties. By using immobilized endo-xylanase and arabinofuranosidase, this technology achieves selective enzymatic hydrolysis that reduces the molecular weight of psyllium arabinoxylan. This process decreases the hydration rate, gel strength, and viscosity of psyllium while maintaining its key functional benefits as a dietary fiber. The controlled depolymerization delays gelation and improves consumer acceptance by enhancing the drinkability of psyllium-based products.
