High Concentration Pullulanase 

Food Grade , Halal & Kosher Certiifed

• Pullulanase PU-720 is produced from Bacillus licheniformis through submerged fermentation, extraction and refining processes. It is so-named because it can specifically hydrolyze pullulan (maltotriose, α-1, 6 glycosidic bond linking polymer). It belongs to amylase which specifically cleaves the α-1, 6 glycosidic bonds of the branching point of amylopectin and cut the entire branch structure to form amylose.

PRODUCT APPLICATIONS AND BENEFITS

• PU-720 is typically used in combination with glucoamylase to produce high glucose syrup and high maltose syrup from liquefied starch.

• Adding pullulanase during saccharification in the production of MSG, alcohol, vinegar, and soy sauce can improve glucose content and shorten sacchrification time.

• Pullulanase has also found its application in the production of high-amylose starches, which can be further processed into “resistant starch” that is not digested in the small intestine but fermented in the large intestine by gut bacteria, producing short-chain fatty acids such as butyrates that are beneficial for colon health. High-amylose starches are also used in adhesive products and in the production of corrugated board and paper.

EFFECT OF PH

• The effective pH range for PU-720 is from 4.0 to 5.0; its optimum pH ranges from 4.2 to 4.6. 

EFFECT OF TEMPERATURE

• PU-720 works effectively at temperatures from 50 to 65°C; its optimum temperature range is from 55 to 60°C.
