Modified Starch

What it is modified starch?

The modified starch it is obtain from the native starch through a physic, chemical or enzymatic, with a modification of molecular structure by molecular cleavage, rearrangement or introduction of new substitute groups.

The most common modification processes include hydrolysis, bleaching, oxidation, esterification, etherification and reticulation of starch.

Modified corn starch is widely used in the paper industry, promoting final product quality and production efficiency. They are present in different stages of manufacturing such as wet-end, spraying, surface sizing.

The use of modified starches makes it possible to improve several characteristics both in the manufacturing process and in the final products of the paper industry. The increase in fiber retention, drainage capacities and load reduction (COD and BOD5) in the effluents of the production process are examples of the benefits of use in the manufacturing process. The final products have features such as improved paper strength, better finishing and print quality.

Applications

The sustainability objectives associated with the use of biodegradable materials make it urgent to use materials that give paper and packaging the properties necessary in the compromise between sustainability and compliance with regulations in this sector. The use of modified starches in the paper industry responds to this commitment.

Modified starch can be used in the production of:
