General Description:

Onion flakes are dried pieces of fresh onion that have been dehydrated to preserve their flavor, aroma, and nutritional value. They offer the taste and aroma of fresh onions in a convenient, shelf-stable form, making them a versatile ingredient in both home and industrial kitchens. Onion flakes rehydrate quickly in liquids and develop a sweeter, milder flavor than raw onions, especially when cooked.

Production Process:

1. Fresh onions are cleaned, peeled, and sliced.

2. Slices are dried using air-drying or dehydrators at controlled temperatures.

3. The dried onion pieces are broken into small flakes and packaged for use.
