PRODUCT SPECIFICATION

Glucoamylase is produced through deep fermentation, extraction, and refinement from the superior strain of Aspergillus niger. It is widely used in industries such as alcohol, liquor, beer, brewing, monosodium glutamate (MSG), starch sugar, and antibiotics.

Glucoamylase (also known as saccharifying enzyme) hydrolyzes the α-1,4 glucosidic bonds of starch from the non-reducing ends to produce glucose. It can also slowly hydrolyze the α-1,6 glucosidic bonds, converting them into short-chain linear polysaccharides.

PRODUCT CHARACTERISTICS

Temperature range: Effective temperature range 35–85℃, optimum temperature range 40–65℃. pH range: Effective pH range 2.5–7.0, optimum pH range 4.0–5.5. Effects of metal ions on enzyme activity: Mg²⁺ activates the enzyme, while Cu²⁺, Zn²⁺, Mn²⁺ and Fe²⁺ inhibit enzyme activity.
