The study on algal polysaccharides with low viscosity is a research item of Shandong province which was taken by Shandong Food & Fermentation Res. & Des. Institute and completed in Dec. 2005 and identified on Dec.9,2005 by Shandong Science & Technological Department.
The technology adopted mechanical shearing degradation to algal polysacchcrides, on the basis of high molecular monomer construction unchanged and without introducing other radicals on the main linkage of the degradation products, the molecular weight of polysaccharide decreased greatly in the solid state, the control of molecular weight was made by controlling time and environment, then the molecular weight grading done by membrane filtration. Compared to the traditional acid-base degradation and enzymatic degradation, it was a safe and reliable physical degradation method with large treatment, best effect and without contamination.
At present, there are 140 hundred million of hypertensives, 325 hundred million of hyperlipemia and 52 million of diabetics in our country. All of them need take medicines to control blood pressure and decrease blood sugar, but medicines brings harmful and side effects to health. The algal polysaccharides are free from side effects and can be taken in daily food and cannot change the flavor and appearance. It can be added in any food.
