Modified food starch pregelatinization

Food Starch, Modified, usually occurs as white or nearly white powders as intact granules and if pregelatinized (that is, subjected to heat treatment in the presence of water), as flakes, amorphous powders, or coarse particles. Modified food starches are products of the treatment of any of several grain-or root-based native starches (for example, com, sorghum, wheat, potato, tapioca, and sago), with small amounts of certain chemical agents, which modify the physical characteristics of the native starches to produce desirable properties.

Tapioca starch and chemically modified tapioca starches are easily converted to instant (pregelatinized) forms (also known as cold-water-soluble starch). This physical modification is brought about by pasting of the starch and subsequent drying as described in Section 12.4. Control of particle size is critical to texture and rehydration rate when the product is redispersed in water.68 Fine particle size results in a smooth texture on redispersion, e.g. in pudding preparation.69 As a comparison, coarse texture could be more desirable in fruit- or vegetable-based foods.

The most physically modified starch produced nowadays is the thermal-treated or pregelatinized starch. These instant starches are hydrosoluble even in cold water and are frequently used as thickeners in foods that receive minimal heat processing. Pregelatinization methods include drum drying, spray cooking, solvent-based processing, and extrusion (Thomas and Atwell 1999). Most instant starch processes...
