About Onion juice

Onion juice is liquid expressed from fresh onions, usually by crushing, grating, or pressing them. It may be strained to remove most solids or left cloudy with fine onion particles, and it is distinct from onion extract or a seasoned onion sauce.

The juice is usually pale, watery, and pungently aromatic, with the sharp, savoury flavour of raw onion. It can be used in cooking or as a source of onion flavour in preparations. Freshly made juice is perishable; bottled products may be processed or contain other ingredients.
