What Is Modified Starch?

Modified starch is obtained by changing the native properties of starch (introducing new functional groups or changing the size of starch molecules and properties of starch granules) by physical, chemical, enzymatic, and other methods on the basis of native starch to make it suitable for certain application requirements. Modified starch has increased functions, new characteristics, improved performance, and expanded application than native starch, which is given by secondary processing.

Distinction of Modified Starch

According to how the starch has been modified, a distinction is shown as follows:

The modified starches applied in papermaking, textile, and other nonfood industries are generally low-end types mainly including cationic starch, hydroxymethyl starch, and oxidized starch. Modified starches applied in the food industry are usually medium- and high-end varieties, commonly including hydroxypropyl distarch phosphate, distarch phosphate, acetylated distarch phosphate, etc.

Technology: The cationic cross-linked starch/PVA composite microspheres

Journal: Polymers

IF: 5.0

Published: 2020

DOI: 10.3390/polym12020289

Background: At present, many methods have been studied to treat wastewater, but no one can simultaneously treat dyes, polyvinyl alcohol (PVA), and starch. In this study, the novel cationic cross-linked starch/PVA composite microspheres (CCSP) were synthesized by reacting cationic starch derivatives with PVA derivatives, and the ability of CCSP to treat textile printing and dyeing wastewater was determined.

Results: The CCSP prepared by the authors has high efficiency in the purification of textile printing and dyeing wastewater, with the ability to simultaneously adsorb dyes, starch, PVA, and other contents, and the adsorption on dyes is much higher than activated carbon (AC). It is worth mentioning that the deactivated CCSP can be converted into recycled AC by chemical method, which realizes the sustainable utilization of the adsorbent. In conclusion, CCSP adsorption is an excellent, green, and sustainable wastewater treatment method, with a good application prospect.
