From a scientific perspective, simply understood, modified starch is a type of starch that has changed its physical and chemical structure under the influence of agents such as temperature, Acid, Enzymes, and Oxidants.
Modified starch is usually derived from tapioca starch, potato starch, tapioca starch, and corn starch. This means that the molecular structure of starch granules will be changed such as creating shorter chain polysaccharide molecules or attaching other substances and groups to the starch molecule.
Depending on each change, different types of starch are produced. Structure and classification Currently, modified starch is made mainly by three main methods: Method of physical modification, Chemical modification method, and Enzyme denaturation method. After being processed by a certain method, native starch changes its original physical or chemical properties to varying degrees.
Based on the inherent characteristics of natural starch, to improve the performance of starch, expand its application range, use physical, chemical, or enzymatic treatment to introduce new functional groups on starch molecules or change the size of starch molecules and the characteristics of starch granules, and change the properties of natural starch, making it more suitable for specific application needs. This changes through secondary processing, the property of starch is called modified starch.
Modified starch is one of the deep-processed products of starch, and as one of the important raw and auxiliary materials in the industry, it is widely used in papermaking, food, textile, medicine, chemical industry, foundry, petroleum, agriculture and forestry, and other industries. The use of modified starch can improve product quality, reduce production costs, replace polluting chemicals, and achieve the purpose of protecting the environment and balancing the ecology.
The modification methods of modified starch include physical modification, chemical modification, and enzymatic modification, among which the chemical modification process is the most. The technological process is: feeding – puffing – cooling – crushing – packaging.
Equipment configuration of modified starch production line:
Screw Elevator → Mixer → Twin Screw Extruder → Cooling Conveyor → Wet Mill → Air Conveyor → Seven-layer Oven → Screw Elevator → Ultrafine Pulverizer
Modified starch is based on natural starch, to improve the performance of starch, expand its application range, use physical and chemical treatment, introduce new functional groups on starch molecules, or change the size of starch molecules and the properties of starch granules, thus changing starch natural characteristics to make it more suitable for the requirements of certain applications. As one of the important excipients of the industry, modified starch can be widely used in paper, food, textile, construction, medicine, and other industries.
Modified Starch Processing Machine is an innovation of twin-screw extruder technology. This technology mainly uses corn starch, potato starch, tapioca starch, wheat starch, etc. as the main raw materials. It is a thermo-chemical process that is high temperature, short time, low moisture, and high energy. Cause it is accomplished in single equipment which is easy to operate and small area cover, its capacity is higher than others.
Huatai Starch Machinery is a large-scale starch project contractor, which can undertake a full set of large-scale starch production lines, including potato starch, cassava starch, sweet potato starch, corn starch, wheat starch, etc.
