Onion Powder

Price Comparison of Fresh Onion and Onion Powder

What Is Onion Powder?

• We can answer the question of what onion powder is as follows:
  It is a product obtained by drying fresh onions, which has concentrated nutritional values and a long shelf life. The water in the fresh onion is evaporated, leaving the essence of the product. The resulting concentrated product, with reduced water activity and bacterial growth potential, is called dried onion. After the production of dried onion, it is ground using special systems to become dried onion.

• What changes when fresh onion is dried? Let's look at the ratios…

  1. Before the drying process, fresh onion contains approximately 91% water.
  2. This water ratio is an environment suitable for rapid bacterial growth and is a moisture level at which the product cannot last for a long time.
  3. As a result of drying, the water in the fresh onion is removed, and the essence of the onion remains.
  4. With the removal of water from the product, approximately 1 kg of Onion powder is obtained from 12 kg of fresh onion.
  5. As a result, shelf life is extended, and the nutritional values (protein, carbohydrates, minerals, fiber ratio) in the dried product increase due to the removal of the essence water.

Advantages of Using Onion Powder

• Using 10 kg of fresh onion, approximately 1 kg of Onion powder is produced, which fits into a small jar.

• Due to volume reduction, the space required for storage is significantly decreased. The required volume is reduced to about 1/10th compared to fresh onion.

• Due to the reduction in volume and weight, it has become an easy-to-transport product. A 20-ton truckload of fresh onion can fit into 2 pallets when dried.

• One of the First Vegetables Used in Space: In NASA Food Research: Onion powder was chosen as one of the first vegetables for astronauts on space missions due to being lightweight, nutritious, and easy to store.

• It does not require cold storage conditions. A cool, dry place away from direct sunlight is sufficient for storing Onion powder.

• The growth rate of bacteria is proportional to the water content in dried onion. During the drying process, the water content of fresh onion drops from 90% to 10%, which lowers water activity and limits bacterial growth in dried onion. After the drying process, the shelf life of the product is much longer than that of fresh onion.

• Historically, the development of dried products has often occurred during periods of famine and war. Products like Onion powder are strategic products for Turkey due to their long shelf life and ease of transport for sustainable food production.

• As Kurucum Food, we continue to develop Onion powder products and production technologies in partnership with our sister company, Eksis Industrial Drying Systems, a manufacturer of drying technologies. Our projects related to dried onion:
