Starch is one of nature’s major renewable resources and a mainstay of our food and industrial economy. Maize or Corn Starch is a typical cereal starch with distinctly low protein and ash contents. The grain is quite nutritious, with a high percentage of easily digested carbohydrates, fats and proteins and hardly any deleterious substances.
Maize starch is a native starch obtained from the wet milling of the whole corn grains. The product is very consistent in quality. Maize Starch powder exhibits all the properties of native starch with some special features such as non-foaming & non-thinning characteristics of boiling solution. Due to its great swelling properties when absorbing liquids, it is used as a thickener agent in many food products. Where high viscosity starch is used, it imparts higher tensile strength to the fiber and thus improves the sizing.
Maize starch is used in the textile industry for sizing of yarns (warp sizing) preparatory to the weaving operations.
Maize starch can be added to the wet – end of the paper manufacturing process. It increases the paper strength, stiffness, rattle of the paper. It is also used in for size press application.
Maize starch pastes are capable of forming film and of binding particles together. It is also uses as a settling agent in ore – refining of iron and bauxite.
