Chemically Modified Hydrocolloids

Introduction

The commonly used synthetic methods for chemical modification are shown in the following table:

Research and Development

Our modified colloids include a series of products such as propylene glycol alginate, amidated pectin, modified starch, and cellulose derivatives. Chemical modifications can not only improve the properties of these colloids, but sometimes lead to entirely new activities. For example, selenium-modified medicago sativa l. polysaccharides possesses antioxidant and neuroprotective activities; ZnO/Zn nanoparticles based on modified starch exhibit superior catalytic ability for photodegradation of dyes; the hydrophilic colloids modified by carboxymethylation can be used as biosorbents to adsorb heavy metal pollutants in water environment.
