Food grade pullulanase for beer brewing industry ENZYMES.BIO PUL2
This product is obtained by deep fermentation of Bacillus Licheniformis.It is widely used in manufacture of beer, starch sugar, monosodium glutamate and alcohol industry etc. The enzyme is a thermal stable debranching enzyme at low Ph (starch α-1,6-Glucosidase).It hydrolyzes the α-1,6–glucosidic linkages and effectively affect on branched chain starch and work in other enzymes (Glucoamylase ,Fungal Alpha- Amylase ).So ,it can quicken reaction speed and improve the content of glucoamylase and maltose
DEFINITION OF UNIT

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

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 human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor.
