Onion processing is a key segment of the global vegetable processing industry. Fresh onions are highly perishable and seasonal, making industrial processing essential for extending shelf life and producing high-value ingredients for the food industry.
Processed onion products, including onion powder, fried onions, and dehydrated onion flakes, are widely used in seasoning blends, snack foods, instant noodles, ready-to-eat meals, and industrial food manufacturing.
If you plan to start an onion processing business, choosing the right production line is critical for efficiency and product quality. GELGOOG provides customized onion processing solutions, including onion powder, fried onion, and dehydrated onion flakes production lines.

Onion powder is produced by dehydrating fresh onions and grinding them into fine powder. It is widely used in spice blends, processed meat, snack flavorings, and instant food products.
Fried onion, also called crispy onion or fried shallots, is commonly used as a topping for noodles, salads, soups, and snacks. Industrial production uses continuous frying to ensure uniform color, crisp texture, and stable quality.
Onion flakes are dehydrated onion slices that retain flavor and texture. They are ideal for soups, seasoning blends, and ready-to-cook meals.
