Functions of Enzymatic Modification

Natural starch receives limitations in industrial applications due to its characteristics and is modified by starch to obtain desirable physicochemical and functional properties. Amylase belongs to the general term of a certain class of enzymes and catalyzes the hydrolysis of intramolecular glycosidic bonds in starch. The advantages of enzymatic modifications compared to other forms of modifications are varied. The specificity and selectivity of the enzyme treatment minimize the formation of undesirable products such as by-products, by-products, and side reactions. During the enzymatic digestion, the reaction is mild, so that the substrate is easily converted into a net product. Used enzymes are recycled and reused. Enzymes are used to modify natural starch and create products with altered solubility, viscosity, or gelation properties that have a wide application in food, paper, textile, and other industries.

Enzymatic Modification Services

At CD BioGlyco, enzyme modification involves the design of starch with new structures, in which molecular weight, branched length distribution, and amylose/amylose ratio are changed by enzymatic reaction. Amylase is divided into internal and external amylase according to the reaction mode of hydrolyzed starch, namely the substrate binding mode of the active site. Endo-amylase is independent of the reducing end of the polysaccharide chain and requires binding to the end of the polysaccharide chain followed by a hydrolysis reaction.

Applications

• In animal feed, starch improves the digestion and absorption of feed, improves the production performance, and improves the utilization rate of feed.
• In the food industry, modified starch increases the volume of the bread and increases the fermentation speed of the dough.
• Modified starch products fructose syrup
• In the textile industry, modified starch reduces the difficulty of dressing.
