右旋糖酐酶,又称α-葡聚糖酶(CAS No.9025-70-1,EC3.2.1.11),它是由细丽毛壳经诱变筛选的高产菌株,经液 体深层发酵精制提取而成的食品酶制剂。
该产品广泛应用于制糖、口腔护理等领域。
作用原理
右旋糖酐酶是一种专一性裂解右旋糖酐分子中的α-1,6 葡萄糖苷键的水解酶,产物主要是异麦芽糖、异麦芽寡糖、 葡萄糖。
产品特性
温度范围:35℃~65℃,最佳温度为 55℃~60℃
pH 范围:有效 pH 为 3.0~8.0,最佳 pH 为 5.0~6.0
产品性状
产品外观: 白色到灰白色粉末
酶活力: ≥400U/mg enzyme powder
酶活力定义:一个右旋糖酐酶单位 U 相当于在规定条件下(pH5.5,55℃,10min),每分钟酶解葡聚糖 (2%葡聚糖 T2000) 产生 1µmol 还原糖所需要的酶量。
产品标准:GB 1886.174-2024《食品安全国家标准 食品添加剂 食品工业用酶制剂》
应用方法
在制糖工业中,由肠膜明串珠菌、链球菌等微生物通过分泌葡聚糖蔗糖酶催化蔗糖生成葡萄糖,葡萄糖进一步聚合形 成右旋糖酐。右旋糖酐是一种高分子量的多糖聚合物,糖苷键的类型主要是α-1,6 糖苷键。右旋糖酐的存在会给制糖 生产带来严重的影响,明显增大糖液的粘度,降低糖液的过滤性,使蔗糖结晶时生成异常形态的晶体,增加了制糖成本,同时影响产品质量。使用右旋糖酐酶,能有效提高蔗汁的加热速度,缩短澄清和结晶时间,消除结晶时的不良影响,从而提高制糖的生产效率及产量。 使用酶活力为 30,000U/g 的产品,在含有 1000ppm 右旋糖酐浓度的蔗汁中,添加 3ppm 酶液,水解效果如下图:
其他用途
可以用来制备小分子右旋糖酐。
Dextranase, called α-glucanase(CAS No.9025-70-1, EC3.2.1.11).
It’s a high-yielding strain from Chaetomium gracile screened by mutagenesis, which is through liquid deep fermentation extract from refining.
It’s widely used in the field of sugar industry, oral care and etc.
Action Principle
Dextranase is a hydrolase for specificity splitting decomposition α-1, 6-glucoside linkages of dextran molecule, which outcome production are mainly isomaltose, isomalto-oligosaccharides and glucose.
Product Characteristic
Temperature range: 35℃~65℃ optimum temperature: 55℃~60℃
pH range: effective pH 3.0~8.0 optimum pH: 5.0~6.0
Product Feature
Product appearance: White to off-white powder
Standard enzyme activity: ≥400U/mg enzyme powder
Activity definition: One dextranase unit is defined as the quantity of enzyme that will liberate reducing sugar at a rate of 1µmol per minute under the condition of hydrolyze dextran (2% dextran T2000) at 55℃ and pH5.5 within 10min.
Product Standard: GB1886.174-2024<<National Food Safety Standard-Food Additives-Enzyme Preparations For Food Industry>>
Application Method
Sugar industry: In the sugar industry, leuconostoc mesenteroides streptococcus and other microorganisms are through secretion glucansucrases catalyze sucrose to glucose, glucose further polymerized to form dextran. The dextran is a high molecular weight polysaccharide polymer, and the type of glycosidic linkage is mainly α-1, 6 glycosidic bond. The existence of dextran will have serious impact on sugar production, obviously increase the viscosity of sugar, reduce the filterability of sugar solution, abnormal crystallization occurs when cane sugar is crystallized, increase the costs of sugar production, and affect the product quality. The use of dextranase can effectively improve the heating speed of cane juice, shorten the time of clarification and crystallization, it can eliminate the adverse impact of crystallization, thereby improve the production efficiency and yield of sugar. Using Dextranase with enzyme activity of 30,000 U/g, in the cane juice which contains 1000ppm dextran concentration, add 3ppm liquid enzyme, the hydrolysis effect is as the chart:

Other Application:
It also can be widely used to prepare small molecule dextran.
