Wide sources and low cost: Starch can be extracted from a variety of plants such as corn, potatoes, wheat, cassava, etc. It is easy to obtain and has a relatively low production cost, so it is widely used in the food and pharmaceutical industries.
Non-toxic and good biocompatibility: Natural starch is non-toxic to the human body, easily digested and absorbed, has good biocompatibility, and is highly safe as an excipient.
Good physical and chemical properties:
Plasticity and viscosity: Starch becomes sticky when heated while wet, and has a certain solidity after cooling, making it useful as an adhesive or filler.
Water absorption and swelling: Starch can absorb water and swell, which helps to increase the volume of the product and improve the taste.
Modifiable: After being modified by physical or chemical methods, starch can have more diverse properties, such as different viscosities, stability, solubility, etc., to meet different application requirements.
Mild taste: The starch itself has a light taste and smell and will not significantly affect the original flavor of the product.
Easy to process: Starch is easy to mix, press, and shape.
Compared to some synthetic polymers, starch is of natural origin and is more in line with consumers' preference for natural ingredients.
Compared to some proteins: Starches are less likely to cause allergic reactions and are generally less expensive.
Compared with some minerals: starch has better plasticity and taste.
Compared to some sugars: Starches are less sweet and provide better structure and viscosity.
