Tag: Seed oil refining

Contrary to a common misunderstanding, household bleach is not used in seed oil production. The "bleaching" step in refining is a specific industrial process that employs activated clays to remove impurities, not harsh chemicals like chlorine, ensuring the final oil is clear and stable.

Deodorization is a critical final step in the refinement of edible oils, with research showing that processes like vacuum steam distillation can effectively remove undesirable odorous compounds. This process is essential for creating the bland, neutral taste and smell that consumers expect in many common cooking oils.

Over 90% of edible vegetable oils undergo a bleaching process using specific chemicals to achieve desired clarity, stability, and taste. Understanding what chemicals are used to bleach seed oils is crucial for comprehending modern food processing and safety standards. This process involves the careful use of adsorbent materials that physically bind and remove impurities rather than chemically altering the oil's core composition.
