INTRODUCTION                                                                                                                                                         
Starch, a high polymeric carbohydrate is a mixture of two polysaccharide, amylose and amylopectin. SUKAMY-MED can change the internal structure of starch, which will decrease the starch viscosity, thereby meeting the requirement in papermaking process.
SUKAMY-MED is an Amylum conversion enzyme derived from the submerged fermentation of Bacillus subtilis. It is mainly used in the pulp and paper making industry.

TECHNICS                                                                                                                                                                   
The function of SUKAMY-MED is equal to starch modifying agent. With unique advantages, it is applicable to various kinds of paper pulp. The surface sizing agent for paper now is usually oxidized starch. The main disadvantages of traditional method of modifying oxidized-starch such as high cost, difficulties in controlling oxidation degree and environment pollution among others, can be easily conquered by enzyme starch modifying technics.

BENEFITS                                                                                                                                                                        
The benefits of using SUKAMY-MED for modifying original starch are easier operation technics, lower cost and no pollution.
This product can still have the indicated activity after three months storage under 25ºC. In lower temperature, the activity of the product will last longer. This product should not be frozen.
