Food Grade α-Galactosidase Enzyme – Processing Aid for Raffinose and Stachyose Reduction

Food Grade α-Galactosidase is a specialized hydrolytic enzyme used in food processing to improve the quality, digestibility, and sensory performance of plant-based ingredients. It is designed to break down α-1,6 galactosidic bonds found in naturally occurring oligosaccharides such as raffinose 和 stachyose, which are commonly present in soybeans, legumes, and many plant protein systems. These oligosaccharides are widely recognized as key contributors to digestive discomfort because they are not efficiently digested in the human upper gastrointestinal tract.

During processing, α-galactosidase enzymatically hydrolyzes these indigestible sugars into smaller, more digestible saccharides, helping manufacturers create products that are gentler on digestion while also delivering a cleaner flavor and smoother mouthfeel. This makes it especially valuable for brands and manufacturers producing soy foods, plant-based beverages, fermented foods， 和 functional nutrition products where consumer expectations for taste, comfort, and ingredient functionality continue to rise.

主要優勢

• Reduces raffinose and stachyose by hydrolyzing α-galactoside bonds commonly found in legumes and soy ingredients
• Improves digestive tolerance by lowering hard-to-digest oligosaccharides that may lead to bloating and discomfort
• Enhances flavor and mouthfeel by supporting cleaner plant-based profiles and smoother texture perception
• Supports better nutrient utilization by reducing oligosaccharide-related anti-nutritional effects in high-legume formulations
• Flexible processing compatibility suitable for soaking, slurry treatment, beverage formulation, and fermentation preparation steps

建議處理條件

• 溫度範圍： 30–50°C
• 酸鹼度範圍： 2.0–6.0
• 建議用量： 0.01–0.5 kg per metric ton (adjust based on substrate and process conditions)

For best results, add the enzyme during a mid-temperature processing stage where pH and temperature fall within the recommended ranges, and allow sufficient time for enzymatic hydrolysis to occur. The ideal dosage depends on multiple factors including the proportion of soy/legume ingredients, solids concentration, residence time, and the desired degree of oligosaccharide reduction. Pilot trials are recommended to determine the most efficient use level for each product and production line.

運作原理

Many plant-based raw materials naturally contain α-galactoside oligosaccharides. Because the human digestive system has limited endogenous α-galactosidase activity, these sugars often pass undigested into the colon, where they are fermented by microbiota and may generate gas. In plant-based food manufacturing, reducing these oligosaccharides during processing can significantly improve end-product tolerance and consumer satisfaction.

α-Galactosidase hydrolyzes α-1,6 galactosidic linkages, converting raffinose- and stachyose-type oligosaccharides into smaller sugars that are more digestible. This enzymatic action can improve product positioning for consumers seeking plant-based nutrition without compromising comfort. In addition, lowering oligosaccharide content often contributes to a smoother sensory profile, especially in soy beverages and legume-heavy formulations.
