How is Potato Starch Manufactured?

While looking for frozen potato products online or in the market, you might have come across a potato starch manufacturer. If you also wondered “what is potato starch?” then you have come to the right place. Potato starch has slowly become one of the most sought-after potato products due to its nutritional value. It is manufactured in large food processing plants.

In the following blog post, we are going to explain the step-by-step process of potato starch manufacturing.

Potatoes Selection

The first step is selecting the highest quality of potatoes that have a uniform shape and high starch percentage (15-22%). Potatoes from cold climate regions are usually higher in starch. The selected potatoes are then sent to the factory for quality control to check for bruises, cracks, or cuts. They are kept in a cold and dry room to prevent moulding and sprouting.

Cleaning & Washing

In the next step, the potatoes are sent for cleaning and washing. A de-sanding machine gets rid of sand or any other small impurities. A cleaning machine washes the potatoes in a rolling cage.

Starch Separation

The potatoes are then peeled and crushed before they are sent for the starch separation process. The crushed potatoes are first mixed with water to separate granules and impurities. Then, all the fibers are removed using a high-speed centrifuge. Finally, a disc separator removes any protein or cell sap leftover.

Dewatering & Drying

The water content of the potatoes is reduced using a vacuum filter. Then the resulting starch mixture goes through a flash dryer or spray dryer that makes a powder containing 12-14% moisture.

Processing & Packaging

In the final step of the manufacturing process, high-speed hot air further dries the wet starch, and then a cyclone separation device separates the starch and air. Finally, the potato starch is vacuum-sealed and packaged to preserve the quality.

Conclusion

The manufacturing process of potato starch is a complex one. A minor carelessness in the quality assurance stage or the potato selection stage can be the difference between high-quality potato starch and unhealthy potato starch.
