Corn / Maize Starch
Starch occurs in nature in many ways. Maize contains about 71% of starch, which can be separated from other ingredients by various processes such as corn wet milling – steeping, grinding, purifying and drying. The physio-chemical and functional properties of starch exhibit a wide variation with slight change in the production parameters. One of the important properties is the viscosity of starch thus making it possible to have diverse uses.
Maize Starch exhibits all the properties of native starch with some special features such as non-foaming & non-thinning characteristics of boiling solution. Hence maize starch has a marginal effect on the efficiency in weaving and paper industry. Where high viscosity starch is used, it imparts higher tensile strength to the fibre and thus improves the sizing.
Combined with resins, starch produces a permanent finish. Good binding capacity results in its use as a good filler and binder in tablets. It is also a vital additive for most of the adhesives due to these properties. In slurry, it provides body to food products. It also helps in retaining the viscosity of foods. Besides this, it is excellent filler in cosmetics by virtue of its smoothness in dry form. It also participates in Maillard’s reaction in presence of proteins and thus gives the brown colour in bakery products.
