Properties of Enzymatic Modification

According to the different reaction modes of hydrolyzed starch, and the different substrate-binding modes of the active site, amylase can be divided into Endoamylse and exoamylase. External amylase needs to bind the ends of the polysaccharide chain and then undergo the hydrolysis reaction. Amylose is composed of D-glucose by α-1,4-glycosidic linkage; the branch position of amylopectin is α-1,6-glycosidic bond, and the rest are α-1,4 glycosidic bonds. Exoamylase cuts the maltose unit or glucose unit from the non-reducing end of the polysaccharide chain, which hydrolyzes the1,4-glucosidic bonds and1,6-glucosidic bonds in starch to produce glucose and dextrin. Different enzymes act on starch will produce different characteristics, in the production by crushing starch particles, adding exoamylase (β-amylases) reduces the ratio of crystal and amorphous region, thus increasing the level of resistant starch, slowing the digestion, these results in the development of healthier starch-based food.

Exoamylase Treatment Service at CD BioGlyco

CD BioGlyco has extensive expertise in the field of exoamylase treatment, including Glucoamylase Treatment, α-Glucosidases Treatment, and β-Amylases Treatment.

We not only provide our clients with raw materials for various enzymes but also provide custom exoamylse treatment lines for each specific need. Our amylase-based native starch is used to produce modification with well-defined and uniform glycosidic bonds, resulting in improved modified starch safety, and consistency. Based on the requirements of different sizes and specific deformation requirements, CD BioGlyco provides a single enzyme or enzyme mixture to better solve your problems in starch modification. 

Advantages

• Starch digestibility is decreased after exoamylase treatment.
• The amorphous components in extruded starch are increased after exoamylase treatment.

CD BioGlyco is dedicated to the research of modified starch production, to provide you with the most satisfactory services. If you are interested in our service, please feel free to contact us for more details.
