2. Process of Starch Extraction from Cassava

2. Process of Starch Extraction from Cassava

The process of starch extraction from cassava is a multi-step procedure that involves several stages to ensure the purity and quality of the final product. Here is a detailed overview of the process:

1. Harvesting:
The first step in the process is the harvesting of mature cassava roots. Cassava plants are typically ready for harvest after 12 to 24 months of growth, depending on the variety and growing conditions.

2. Washing and Peeling:
Once harvested, the cassava roots are thoroughly washed to remove soil and debris. The outer skin is then peeled off to expose the starchy interior. This step is crucial for removing impurities and preparing the roots for further processing.

3. Grating or Crushing:
The peeled cassava roots are then grated or crushed into a fine pulp. This step breaks down the cell walls of the cassava, releasing the starch granules.

4. Washing and Sifting:
The crushed cassava is washed with water to separate the starch from the fibrous material. The mixture is then passed through a sieve or filter to remove the larger particles, leaving behind a slurry of starch in water.

5. Settling and Decanting:
The starch slurry is allowed to settle, causing the heavier starch particles to sink to the bottom. The water, which is lighter, is decanted off, leaving a thick layer of wet starch.

6. Drying:
The wet starch is then spread out to dry, either in the sun or using mechanical dryers. This step is essential for removing moisture and making the starch suitable for storage and transportation.

7. Milling and Sifting:
Once dried, the cassava starch is milled to achieve a fine, powdery texture. It is then sieved again to remove any remaining impurities and to ensure a uniform particle size.

8. Packaging:
The final product, now a high-quality cassava starch, is packaged in appropriate containers for distribution to various industries.

9. Quality Control:
Throughout the process, quality control checks are performed to ensure the starch meets the required standards for purity, moisture content, and particle size.

This process can vary slightly depending on the specific requirements of the industry using the cassava starch. However, the general steps outlined above provide a comprehensive view of how cassava starch is extracted from the root and prepared for various applications.
