Rice Starch Production Process

Rice is a staple food for millions of people around the world, not only providing essential nutrients but also containing valuable components like rice protein and starch. Deli Foods is a leader in the food processing industry, specializing in the production of raw rice for various applications. With years of experience and state-of-the-art manufacturing facilities, we ensure the highest standards of product quality and safety. Today we will share about the innovative process of extracting rice protein from rice grains and preparing rice starch. This method provides a simple and efficient method for obtaining high-quality rice protein and starch, which is suitable for large-scale industrial production.

1. Soaking: Rice grains are soaked in an alkaline ion-type solution for a period of 4 to 40 hours. This soaking process prepares the rice grains for further extraction.
2. Grinding and Soaking: The soaked rice grains are finely ground, and the resulting rice slurry is subjected to further soaking at a temperature range of 20 to 90℃ for 2 to 20 hours. This step facilitates the release of rice protein from the grains.
3. Separation: After the soaking process is complete, the rice slurry is separated using a centrifugal separator. During this step, rice starch is directed to the next stage of starch production, while rice protein is retained for further processing.
4. Acid Precipitation: The separated rice protein solution is adjusted to a specific pH value using an acid ion-type coagulant. This adjustment causes the rice protein to precipitate, separating it from the solution.
5. Washing: The precipitated rice protein is thoroughly washed with clean water to remove any impurities.
6. Homogenization: The washed rice protein is subjected to homogenization using a high-pressure homogenizer. This process ensures the consistency and quality of the extracted rice protein.
7. Drying: Finally, the homogenized rice protein is spray-dried to obtain rice protein powder with a protein content of at least 70% and moisture content ranging from 5% to 15%.

Preparation of Rice Starch:

The second part of the process focuses on the preparation of rice starch, which involves the following steps:

1. Washing: The rice starch separated during Step 3 of the rice protein extraction process is washed using a cyclone to obtain refined rice starch milk.
2. Drying: The refined rice starch milk is then subjected to air drying, resulting in the production of high-quality rice starch. The rice starch obtained through this method contains less than 1.0% of rice protein.

The process of extracting rice protein and preparing rice starch from rice grains is an ingenious method that ensures the efficient utilization of rice resources. This method not only yields high-quality rice protein suitable for human consumption but also allows for the recovery of rice protein that can be used as feed for livestock and poultry. Additionally, the resulting rice starch exhibits excellent characteristics, making it valuable in various industries, such as cosmetics, textiles, and photography. The simplicity, cost-effectiveness, and reliability of this production process make it ideal for large-scale industrial applications, meeting the high demand for rice protein and starch in the market.
