Found this info on the website for the Organic Consumers Association:
- Silk’s Light soymilk, as well as its “Heart Health” soymilk, is made with hexane-extracted soy flour instead of whole soybeans. Hexane is a highly explosive volatile solvent. It is a byproduct of gasoline refining and a neurotoxin. Soybeans used in Silk’s Light and Heart Health soymilk are immersed in this neurotoxic petrochemical to make soy flour, which is listed as the main ingredient in these Silk products.
- Hexane is classified as a “hazardous air pollutant” by the Environmental Protection Agency and emissions are regulated for their contribution to air pollution. Food processors are the country’s major hexane emitters. When The Cornucopia Institute sent samples of hexane-extracted soy flour to an independent lab for residue testing, residues as high as 21 parts per million were found. The effects on consumer health of repeated and long-term consumption of hexane-extracted soy ingredients have not been thoroughly studied. An extraction process that does not involve hexane is available, but using hexane is cheaper for the processor.
- Silk’s creamers and Silk Plus Omega-3 DHA contain other minor hexane-extracted ingredients-soy lecithin and algal oil, respectively. Moreover, the Cornucopia Institute has received reports from parents of toddlers and children who experienced diarrhea and stomach upset from the DHA used in Silk (Life’s DHA by Martek Biosciences Corporation). This is the same additive, found in infant formula (extracted from algae and soil fungus), that has been linked to severe adverse reactions in infants. (Cornucopia has obtained adverse reaction reports from the FDA verifying this unfortunate health side-effect.) The FDA has never tested the safety of Life’s DHA, relying instead on safety data supplied by the same corporation that has a financial interest in selling and placing these additives in foods. The FDA did, however, indicate serious reservations regarding the safety of these additives.
