What is onion juice?

Published in Food science 1 min read

Onion juice is a liquid extracted from onions, typically by squeezing, using a juicer, or blending and straining chopped onions.

Here's a breakdown of how it's made:

  • Preparation: Onions are peeled and chopped into smaller pieces.
  • Extraction Methods:
    • Juicing: Onion pieces are fed into a juicer, which separates the juice from the pulp.
    • Squeezing: Chopped onions are pressed or squeezed to release their liquid.
    • Blending and Straining: Onion pieces are blended into a paste, and then the paste is strained to separate the juice.

Onion juice is known for its strong flavor and odor. While it can be consumed directly (often in small amounts due to its potency), it is frequently used as an ingredient in cooking or as a home remedy.
