DESCRIPTION Pullulanase PU-700 is derived from selected strains of Bacillus licheniformis by submerged fermentation and refining extraction process. This enzyme is especially used for hydrolysisof Pullulan (a polymer connected by maltotriose with α-1,6 glycosidic bonds). PU-700 can efficiently cut α-1,6 glucosidic bonds of the amylopectin , then cut the entire branch structure to produce amyloase.
Glucoamylase is very effective in hydrolysis of alpha-1, 4 glycosidic bond; however, glucoamylase is slow in hydrolysis of alpha-1, 6 glycosidic bond, the presence of which constitutes an obstacle in the production of high-glucose syrup. Using pullulanase can synergize together with glucoamylase during the saccharification stage, hence effectively improve the rate of hydrolysis of starch, reduce the dosage of glucoamylase, shorten the reaction time and increase the yield and purity of the glucose.
In the production of maltose, alpha-amylase is first used to liquefy the starch, then fungal alpha-amylase or beta-amylase shall be used to decompose starch, so the maltose content of the final product is about 50% to 60%, referred to as a high maltose syrup. While the synergistic effect of the use of pullulanase with alpha-amylase and beta-amylase, the maltose content in the final product can reach more than 80%, hence produce Exltra-High Maltose Syrup.
Standard packaging is 25kg, 30kg food-grade HDPE drums or 1125 kg IBC totes.
Typical shelf-life is six months if this product is stored below 25°C in its original packaging, sealed and unopened, protected from sunlight. Its shelf-life will be eighteen months if this product is stored properly at 0 ∼10°C. This product has been formulated for optimal stability. Prolonged storage and/or adverse conditions such as higher temperature may lead to a higher dosage requirement, therefore should be avoided.
