in order to select modified starch for a particular application, consideration about both the market and production are required.
modified starches consist of starch with low to very low level of substituent group. enzymatic modification of starch is hydrolysis of some part of starch into a low molecular weight of starch called maltodextrin, or dextrin using amylolytic enzymes. they are widely used for food and pharmaceutical industries.
Physical modification involves pre - gelatinization, and heat - treatment of starch, ect. Pre - gelatinized starches are pre - cooked starches that can be used as thickener in cold water. while the heat - treatment processes include heat - moisture and annealing treatments, both of which cause a physical modification of starch without any gelatinization, damage to granular integrity, or loss of birefringence
