Food Grade Inulinase (Fructan Hydrolase) – Inulin Enzyme for Fructooligosaccharide Production | For Food, Beverage, Dairy & Pharmaceutical Applications

Food Grade Inulinase (also known as Inulin Enzyme or Fructan Hydrolase, EC 3.2.1.7) is a specialized enzyme preparation developed for the controlled hydrolysis of inulin and other fructans. It is widely applied in the food, beverage, dairy, and pharmaceutical industries as a processing aid to produce fructose, fructooligosaccharides (FOS), and value-added functional ingredients.

This product is positioned for broad industrial use, especially in applications involving food production and food additives. It is suitable for manufacturers seeking efficient enzymatic conversion of inulin into shorter-chain fructans and fermentable sugars with enhanced functional and nutritional properties.

产品概述

Inulinase catalyzes the hydrolysis of β-2,1-D-fructosidic linkages within inulin molecules. By cleaving these bonds, the enzyme converts inulin into fructose, glucose, and a range of fructooligosaccharides including GF2, GF3, GF4, F2, F3, F4, and F5. Depending on process conditions and substrate concentration, the enzyme can be used to produce short-chain FOS or higher fructose syrups for diversified industrial needs.

Inulin itself is a natural linear fructan composed of D-fructose units linked by β-2,1-glycosidic bonds, usually terminated by a glucose unit connected via an α-1,2 bond. It is a naturally occurring polysaccharide with a degree of polymerization (DP) generally ranging from 2–60, and in some cases reaching up to 100. The molecular structure is commonly expressed as GFn, where G represents the terminal glucose, F represents fructose, and n represents the number of fructose units, n=2~60.

Through enzymatic hydrolysis, inulinase enables precise modification of fructan chain length, allowing manufacturers to tailor sweetness, solubility, and functional performance in finished formulations.

作用机制

Inulinase is classified as an endo-inulinase, meaning it randomly cleaves internal β-2,1-fructosidic bonds within the inulin molecule. This internal cleavage generates glucose (G), fructose (F), fructooligosaccharides (GF2–GF4), and short-chain fructans. The enzyme acts efficiently under controlled processing conditions and plays a critical role in the industrial production of fructooligosaccharides and related high-value ingredients.

By breaking down inulin into lower molecular weight fructans, the enzyme improves fermentability, enhances sweetness modulation, and supports the development of functional food and beverage products.
