bacillus licheniformis enzyme,
starch digesting enzyme
An ideal enzyme for the production of high glucose syrup and high maltose syrup.
Pullulanase PU-720 is produced from selected strains of Bacillus licheniformis by submerged culture, refine and extraction processes. Pullulanase is so-named because of its specific hydrolysis of pullulan (maltotriose, α-1, 6 glycosidic bond linking polymer). It is amylase that can specifically cleave the α-1, 6 glycosidic bond of the branching point of amylopectin, and cut out the entire branch structure to form amylose.
PU-720 is typically used in combination with glucoamylase for the production of high glucose syrup and high maltose syrup from liquefied starch.
|Systematic Name:||EC 220.127.116.11, Pullulan 6 - glucanohydrolase|
|Appearance:||Sepia brown liquid|
|Activity:||1400 BU/ml (minimum)|
|Product pH:||3.0 to 5.0|
|Specific gravity:||1.10 to 1.20 g/ml|
EFFECT OF PH
PU-720 can work with pH from 4.0 to 5.0; For maximum activity, the optimal pH is from 4.2 to 4.6.
EFFECT OF TEMPERATURE
Generally, the effective temperature range for PU-720 is from 50 to 65°C. For maximum activity, the optimal temperature range is 55 to 60°C.
APPLICATION & BENEFITS
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
|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. With 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 ultra-high-maltose syrup.
|In production of beer, if the starch is not completely decomposed, the fermentable|
sugar content will be decreased, and the beer made from fermentation will not reach
the requirements. The synergistic effect of pullulanase and alpha-amylase will enable
pullulanase to completely decompose starch in the raw materials, reduce the wort
content in the beta-limit dextrin, increase the content of the fermentable sugar, thus
greatly improve the fermentation efficacy.
|Others||Adding pullulanase during saccharification in production of MSG, alcohol, vinegar, and|
soy sauce can improve glucose content and shorten sacchrification time.
Use of pullulanase in modified starch, such as potato starch, corn starch and sweet
potato starch, can increase the content of resistant starch by de-branching, gelatinization and aging process. After de-branching, the starch can produce more short-chain and cross linking through hydrogen bonding and hydrophobic interactions in the regenerative process, aggregation of forming a crystalline structure,i.e. slowly digestible starch. In the natural starch of plants, the amylose only accounts for about 22% to 26%, whilst the majority content is amylopectin. Using pullulanase can cut amylopectin molecules in the alpha-1,6-glycosidic bond, transfer amylopectin into amylase with higher purity.
Standard packaging is 25kg, 30kg food-grade HDPE drums or 1125 kg IBC totes.
