alpha-Galactosidase: High activity enzyme to digest RFO fibers.
Applications: include: Food processing, animal feed, pharmaceuticals, and biotechnology to break down indigestible α-galactoside sugars.
Properties: Our alpha-Galactosidase enzyme delivers an effective, targeted solution for breaking down alpha-galactosides such as raffinose and stachyose that are naturally present in legumes, grains, and vegetables. By converting these complex sugars into easily digestible simple sugars, the enzyme improves digestibility, nutrient availability, and consumer comfort, helping reduce gas and bloating. Designed for high activity and stability across food-processing conditions, it integrates seamlessly into food, feed, and nutraceutical applications, supporting cleaner labels and improved product quality. With consistent performance, reliable supply, and technical support to optimize dosing, our alpha-galactosidase enables manufacturers to deliver better tolerance, enhanced functionality, and greater value in plant-based and digestive health products.
