Parboiling In Rice Milling

Parboiling process involves the hydrothermal treatment of paddy before milling. The advantage of the parboiling process stems from the gelatinization of rice starch and hardening of rice kernel that it brings about. As a result, breakage losses during milling of rice can be minimized. Five major steps in the parboiling process are required, as follows

• Soaking paddy in water (cold or lukewarm water) to increase the moisture content.

• Steaming paddy to achieve partial gelatinization.

• Drying paddy to save the moisture content for storage and milling.

• Husking to remove paddy husk from paddy kernel.

• Milling to remove bran from brown kernel.
