Detailed introduction to Alpha Amylase Enzyme:
COLOTEMPASE -Bacterial Mid-Temperature Alpha-Amylase
DESCRIPTION
COLOTEMPASE is a bacterial endo -amylase (EC 3.2.1.1) preparation derived from Bacillus subtilis. The enzyme catalyzes the hydrolysis of starch in mid-high temperature like 60-80. The enzyme hydrolyzes the -1,4-glucosidic linkages of gelatinized starch randomly to soluble dextrin, reducing the high viscosity of the starch slurry and disappearing blue color of starch-iodine complex.
COLOTEMPASE is high concentrated enzyme designed for the desizing of fabrics sized with starch.
COLOTEMPASE can be used for all types of desizing process, like any pad roll process and any continuous desizing process, and gives sufficient results.
