Food Grade Inulinase Powder 10,000 U/g

Product Description

Inulinase (CAS No.9025-67-6, EC3.2.1.7) is derived from Aspergillus Niger which produced from submerged fermentation.

It is mainly used to hydrolyze inulin into fructo-oligose, which can be widely used in many fields such as food, beverage and dairy products.

Action Principle

This Inulinase is a endo-inulinase, which can hydrolyze β-2 , l-d- glycosidic bond of fructosan from inulin internal to form fructo-oligose.
