Amphoteric Starch

We make, export and supply of Amphoteric Starch in Dondaicha, Maharashtra, India. The word "amphoteric" implies that a chemical product has both positive and negative ion groups when it is dissolved in solution. When papermakers refer to amphoteric starches they are usually referring to products derived from corn starches. The least expensive starch products are based on dent corn, a corn variety that is also the source of most corn sweetener. Amphoteric starches also are prepared from waxy maize, a variety of corn that produces only the branched type of starch, amylopectin. The cationic groups are the same quaternary ammonium substituents used in preparation of cationic starches. The anionic groups usually are phosphates. Strictly speaking all cationic potato starches are really amphoteric starches since potato starch contains about 0.08% phosphorous. The cationic content of amphoteric starches is typically in the range of 0.2 to 0.3% nitrogen. All of these products are delivered to the mill as a dry powder having a moisture content of 10 to 20%.
