Industrial Starch Modification Technology
Native starches may require improved functional properties when exposed to demanding processing conditions such as low pH, high mechanical shear, elevated temperatures, or freeze-thaw cycles.
Our modified starch processing solutions are designed to tailor the functional properties of native starch through controlled physical, chemical, or enzymatic treatments, providing improved viscosity control, texture stability, thermal resistance, water retention, and processing performance according to specific application requirements.
Turnkey Engineering & Reaction Automation
We design and integrate automated starch modification systems with process controls for key parameters including temperature, pH, reagent dosing, mixing, and reaction time.
Depending on the modification technology and product requirements, the process may incorporate controlled reaction systems, washing and purification units, dewatering equipment, drying systems, and automated material handling. PLC-based process control and monitoring systems can be integrated to support consistent operating conditions, process traceability, and product quality.

Modified Starch Production Flowchart
The modification and refining process is configured according to the selected starch type and required product specifications:
Slurry Preparation
Native starch is dispersed in purified water in stainless-steel mixing tanks under controlled concentration, agitation, and temperature conditions to produce a uniform starch slurry.
Controlled Modification
Depending on the required product grade, physical, chemical, or enzymatic modification is carried out under controlled process conditions (esterification, etherification, cross-linking, or oxidation).
Reaction Control & Neutralization
Reaction conditions are monitored and controlled. Where applicable, the slurry is neutralized by controlled pH adjustment using automated dosing systems.
Washing & Purification
The modified starch slurry undergoes controlled washing and purification stages to reduce soluble salts, residual reagents, and other process impurities.
Dewatering
The purified starch slurry is mechanically dewatered using suitable separation equipment, such as peeler centrifuges or vacuum filtration systems.
Drying & Conveying
The dewatered starch is dried under controlled conditions using flash drying technology and conveyed pneumatically to storage silos or packaging systems.
