Glucoamylase for low-cal beer

 PRODUCT DESCRIPTION

The product is produced by mixing carefully optimized proportion of glucoamylase and pullulanase produced separately from safe microbial strains by submerged fermentation, separation and purification. The combination of glucoamylase with supplementary pullulanase makes saccharification more efficient by avoiding limit dextrin and by-product formation, and therefore saving processing cost while producing more glucose.

Pullulanase is a type of isoamylase which can selectively hydrolyze α-1,6-glucosidic linkage in pullulan, starch and oligosaccharides, thereby, making the complete hydrolysis of branched starch possible. When used together with glucoamylase, it speeds up saccharification by degrading α-1,6-glucosidic linkage and increases glucose yield.

The recommended dosage is 0.04-0.1% on basis of dry malt in mashing. When added in fermentation a dosage range of 20-50ml/t of wort is suggested. The dosage has to be optimized based on each application, the raw material specifications, product expectation and processing parameters. It is better to begin the test with the convenient volume.

Enzyme preparations are proteins that may induce sensitization and cause allergic type of symptoms in susceptible individuals. Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa. Any direct contact with human body should be avoided. If irritation or allergic response for skin or eyes develops, please consult a doctor.

Keep sealed after use every time to avoid microbial infections and inactivation of enzymes until its finish.

ØPackage：25kgs/drum.

ØStorage： Keep sealed in a dry and cool place and avoid direct sunlight. Slight sedimentation is acceptable since it will not impact performance of the product.
