1. Seed oils used in food are food grade. Calling them “industrial” is for fearmongering purposes. 2. Many different food ingredients are used in many different industries. That tells you absolutely nothing about the safety or the nutrition of an ingredient in food. This is brought up for fearmongering purposes. 3. Deodorization is a simple distillation process. This operation allows for the elimination of free fatty acids and removes odors, different off-flavor components and contaminant. Careful execution of this process also improves the stability and color of the oil, whilst preserving its nutritional value (PMID: 35069038). 4. Hexane has been used to extract oils from plant material since the 1930s. There is no evidence to substantiate any risk or danger to consumer health when foods containing trace residual concentrations of hexane are ingested. Refined vegetable oils extracted with hexane contain less than 1 ppm of residual hexane. It’s estimated that the level of ingestion of hexane from all food sources is less than 2 percent of the daily intake from all other sources, primarily gasoline fumes. 5. Deodorized oil quality is evaluated primarily by traditional quality parameters such as a low residual FFA content, a high oxidative stability, a light color and a bland odor and taste. In addition, high-quality food oils need to contain low trans fatty acid (TFA) levels, high amounts of natural antioxidants (tocopherols), low levels of polymeric and oxidized triglycerides and no contaminants or degradation products (https://lipidlibrary.aocs.org/edible-oil-processing/deodorization). 6. The objective of bleaching (or decolorizing) is to reduce the levels of colored pigments (carotenoids and chlorophylls). It indirectly impacts the deodorized oil color. To perform bleaching, adsorption bleaching clays, activated carbon, special silica, or a combination of these are used (PMID: 35069038). Studies regarding health impacts are linked in the comments.
