Inulinase Powder
Is inulinase the same as fructan hydrolase?
Inulinase is a specific type within the fructan hydrolase family. It mainly catalyzes the hydrolysis of β-(2→1) fructans (inulin), while fructan hydrolases refer to all enzymes capable of degrading fructans. The two have a "specific-to-general" relationship.

Mechanism of action:
Inulinase works by breaking the β-2,1-glycosidic bonds in inulin, producing fructose or fructooligosaccharides. Exo-inulinase releases fructose from chain ends, while endo-inulinase cuts internally to generate FOS for various food applications.

Fructo-oligosaccharide (FOS) Production
Inulinase hydrolyzes inulin to produce fructo-oligosaccharides, widely used in functional foods, beverages, and dietary supplements, providing a natural sweetener alternative with prebiotic properties and improved taste profile.
Fermentation Industry
By converting inulin into fermentable sugars, inulinase supports the production of ethanol, organic acids, and other fermentation-derived products, improving substrate utilization and fermentation efficiency.
Low-Calorie and Reduced-Sugar Foods
Inulinase-derived fructo-oligosaccharides provide natural sweetness with low caloric content, making it suitable for developing reduced-sugar, low-calorie, or "sugar-friendly" food products.
High Substrate Specificity: Exhibits strong specificity for β-(2→1) glycosidic bonds in inulin, efficiently hydrolyzing inulin into fructose or fructo-oligosaccharides with minimal side reactions, ensuring consistent product quality.
pH Stability: Inulinase is highly stable in a moderately acidic range of pH 4.0–6.0, with optimal stability at pH 4.5–5.5, ensuring consistent performance in various food processing applications.
Q1: What does inulinase break down?
A: Inulinase primarily acts on inulin, a fructan with β-(2→1) linkages, converting it into fructose, inulo-oligosaccharides, and minor glucose. Its activity on sucrose or levan-type fructans is minimal.
Q2: What is the main function of inulinase?
A: The main function of inulinase is to hydrolyze inulin's β-(2→1) bonds, producing fructose and inulo-oligosaccharides. It is widely applied in inulin processing and fructo-oligosaccharide production for food and ingredient applications.
Q3: Is inulin the same as inulinase?
A: No. Inulin is a naturally occurring fructan polysaccharide, while inulinase is the enzyme that breaks it down into smaller sugars. They are completely different entities: substrate versus catalyst.
