A flowability agent is a substance that enhances the flow of a material, making it easier to handle and transport. In the food industry, flowability agents are used to improving the handling and processing characteristics of powders, granules, and other food ingredients. This helps to improve productivity, reduce waste and minimize handling damage, as well as making the food ingredients easier to dispense, package, and transport.
The flowability of modified starch refers to its ability to flow freely and continuously under given conditions. It is an important characteristic for various industrial applications including food, papermaking, pharmaceuticals, and construction. In the food industry, improved flowability can lead to better mixing and handling of food ingredients. In papermaking, it can result in improved paper strength and uniformity. In pharmaceuticals, it can lead to more efficient production processes. In agriculture, improved flowability can lead to better application of fertilizer and seed. Modified starch can be made more flowable through various methods, such as increasing its molecular weight or decreasing its viscosity.
The flowability of native starch and modified starch may vary depending on the specific type of starch and the degree of modification. In general, modified starches tend to have improved flowability compared to native starches, due to the chemical or physical changes to the starch molecules that affect their viscosity, gelling and swelling properties. Some modified starches can provide a more uniform and smooth flow, making them useful as flowability agents in food and other industries. On the other hand, native starches may have a less consistent flow, leading to clumping and clogging in certain applications.
