The difference between pregelatinized starch and ordinary starch There are obvious differences between pregelatinized starch and ordinary starch in many aspects.
First of all, pregelatinized starch is a processed starch, while regular starch is an unprocessed natural starch. Pregelatinized starch is to process wet starch before the starch is gelatinized, and use thermal, mechanical or chemical methods to expand and spread the starch granules in water or other solvents to form a uniform starch paste. Ordinary starch is a natural starch extracted and isolated from plants.
Secondly, pregelatinized starch and ordinary starch are also different in physical and chemical properties. Pregelatinized starch has better water solubility, viscosity and stability, can quickly gelatinize in cold water, and has higher viscosity and transparency. Ordinary starch requires heating to gelatinize and has a lower viscosity.
In addition, the uses of pregelatinized starch and ordinary starch are also different. Pregelatinized starch is widely used in food, pharmaceuticals, cosmetics and other fields, such as as an improver in baked goods, as a drug carrier in pharmaceuticals, and as a moisturizer in cosmetics. Ordinary starch is mainly used to make various foods, paper, textiles, etc.
In short, although pregelatinized starch and ordinary starch are both starches, their processing processes, physical and chemical properties, and uses are different. Therefore, it is necessary to choose the appropriate starch type according to the specific situation when using it.
