Food Grade Pullulanase For Beer Brewing Industry Enzymes.Bio Pul2
Introduction
This product is obtained by deep fermentation of Bacillus Licheniformis. It is widely used in the manufacture of beer, starch sugar, monosodium glutamate, and alcohol industry, etc. The enzyme is a thermally stable debranching enzyme at low pH (starch α-1,6-glucosidase). It hydrolyzes the α-1,6-glucosidic linkages and effectively affects branched chain starch and works with other enzymes (Glucoamylase, Fungal Alpha-Amylase). So, it can quicken reaction speed and improve the content of glucoamylase and maltose.
Definition Of Unit
1 unit of Pullulanase equals to the amount of enzyme needed to liberate 1µmol of reducing sugar (Calculated as glucose) from pullulan in one minute at pH 5.8, 50℃.

Recommended Dosage
In the manufacture of beer: The recommended dosage is 0.4-0.8 L of the enzyme preparation per ton of total raw materials. Pullulanase can reduce the content of amylopectin to produce dry beer.
In the manufacture of glucose: The recommended dosage is 0.35-0.6 L per ton of dry starch. Pullulanase and glucoamylase together are used in the saccharification step. The usage of pullulanase can improve the yield of glucose by reducing the content of amylopectin and can reduce the usage of glucoamylase.
In the manufacture of maltose: The recommended dosage is 1-2 L per ton of dry starch. Pullulanase and Fungal Alpha-Amylase can be used together in the saccharification step. The usage of Pullulanase can improve the yield of maltose and can produce maltose syrup with a content of 70% maltose.
Package

Safety
Enzyme preparations are proteins, which may induce sensitization and cause allergic-type reactions in sensitized individuals. Prolonged contact may cause minor irritation for skin, eyes, or nasal mucosa, so any direct contiguity with the human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor.
