Dextranase (EC 3.2.1.11, CAS 9025‑70‑1) is a glycoside‑hydrolase enzyme mainly produced by fungi or bacteria. It specifically cleaves α‑1,6 glycosidic bonds within dextran, a high‑molecular‑weight glucose polysaccharide, breaking long polymer chains into smaller oligosaccharides and glucose fragments.
Widely applied in cane‑sugar processing, it reduces syrup viscosity and improves filtration efficiency and sugar yieldPMC. It is also used in oral‑care products to decompose dental‑plaque biofilms, plus pharmaceutical and biotech fields for low‑molecular‑weight dextran preparation. Commercial forms include liquid and powder for food‑grade industrial use.
Dextranase (EC 3.2.1.11) is a food‑grade glycoside hydrolase that specifically breaks α‑1,6 glycosidic bonds of dextran polymers, producing isomalto‑oligosaccharides and glucose fragments. It functions mainly as a processing aid across multiple food sectors under global food‑safety regulations.
Its largest food application lies in cane‑sugar and beet‑sugar manufacturing. Microbial contamination during sugar‑crop harvesting generates high‑molecular‑weight dextran, which sharply raises juice viscosity, blocks filters, slows crystallization and lowers sucrose yield. Added to raw juice, syrup or molasses, dextranase degrades unwanted dextran, improves fluidity, cuts filtration time and increases final sugar output. Most enzyme residues are removed during sucrose crystallization, leaving no active enzyme in refined sugar productsEFSA.
Dextranase supports beverage and brewing production as well. In beer, fruit‑juice and wine processing, residual dextran causes high wort viscosity and poor clarity. The enzyme reduces liquid thickness, accelerates filtration and enhances product brightness and shelf‑time stability without altering core flavour profiles. Treated sugar syrups are further applied in soft drinks and functional beverages for consistent sweetness control.
Besides process optimisation, dextranase helps manufacture functional food ingredients. Controlled hydrolysis of dextran yields isomalto‑oligosaccharides, a prebiotic ingredient that stimulates growth of beneficial gut bacteria. These oligosaccharides are incorporated into baked goods, dairy products and snack foods to enrich nutritional value and improve texture and water‑holding capacity.
It also appears in oral‑care food‑related formulations such as chewing‑gum products. By decomposing glucan‑based plaque matrix formed from sucrose metabolism, dextranase restrains dental‑plaque accumulation and delivers anti‑caries benefitsPMC.
As a mild, eco‑friendly biocatalyst, dextranase replaces harsh chemical degradation methods, lowers energy input and reduces waste for modern food factories. It must be produced from approved microbial strains and dosed following local regulatory limits for food‑enzyme safety.
