右旋糖酐快速测定与清除技术

广东省生物工程研究所（广州甘蔗糖业研究所）

制糖原料（甘蔗、甜菜）和加工物料中的高粘性右旋糖酐，是由细菌消耗蔗糖产生，其存在意味着糖分损失和加工困难增加，导致能耗物耗增加、产糖率和产品质量下降，给制糖及炼糖企业造成严重经济损失。

我单位已成功开发出右旋糖酐单抗检测试剂盒和性能优异的右旋糖酐酶，解决了右旋糖酐快速测定与清除的行业难题。其中，右旋糖酐单克隆抗体用于对右旋糖酐进行快速、专一、灵敏的测定，右旋糖酐酶可高效水解右旋糖酐至小分子的糖。该技术成果已在中国、美国、英国、德国、墨西哥等国家的糖厂或相关机构应用或试验。

右旋糖酐单抗检测系统包括：

（1）右旋糖酐单抗试剂盒（可测10个样/盒）

含抗体冻干粉及稀释液

（2）微量浊度计，配1cm四面透光比色皿

（3）微量移液器

该方法适用于监测甘蔗、甜菜、原糖等原料，加工物料、糖产品及糖蜜中的右旋糖酐含量，其优点是操作简便、5分钟出结果。

我们也提供定制酶活的右旋糖酐酶粉剂或液体，适用于甘蔗/甜菜制糖和原糖精炼。

Method for Rapid Detection and Fast Removal of Dextran in sugar industry

Guangdong Bioengineering Institute
（Guangzhou Sugarcane Industry Research Institute）

The high viscosity dextran in raw materials and processing materials for cane/beet sugar production is produced from sucrose by bacteria. The presence of dextran means sucrose loss and increasing processing difficulty, which results in an increase of energy and material consumption, decrease of sugar production and quality, and severe economic loss to sugar mills and refineries.

GBI has successfully developed dextran monoclonal antibody（mAb）detection kit and dextranase with excellent performance, which makes it possible to detect and remove dextran rapidly. Dextran mAb is exclusively used for rapid and sensitive detection of dextran, and dextranase is used for efficient hydrolysis of dextran into small molecular carbohydrates. This method has been widely applied or tested in China, the United States, the United Kingdom, Germany, Mexico, etc.

The dextran detection system includes:

(1) dextran monoclonal antibody kit with anti-dextran mAb freeze-dried powder and diluent, 10 tests per kit.

(2) micro nephelometer equipped with a 1cm four-side light transmission cuvette.

(3) micro pipette.

The content of dextran can be easily detected from sugarcane, beet, raw sugar, processing materials, molasses and sugar products within 5 minutes with this system.

GBI also provides powder or liquid dextranase with customized enzyme activity, which is suitable for fast removal of dextran in cane/beet sugar production.
