Former Utne Reader senior editor Keith Goetzman on environmental issues from climate change to composting.
In order to meet the demands of health-conscious consumers, manufacturers of soy-based fake meat like to make their products have as little fat as possible. The cheapest way to do this is by submerging soybeans in a bath of hexane to separate the oil from the protein. Says Cornucopia Institute senior researcher Charlotte Vallaeys, “If a non-organic product contains a soy protein isolate, soy protein concentrate, or texturized vegetable protein, you can be pretty sure it was made using soy beans that were made with hexane.”
These veggie burgers are made with hexane:
Boca Burger (conventional)
It’s All Good Lightlife
Yves Veggie Cuisin
While these veggie burgers are hexane-free:
Boca Burgers “made with organic soy”
Morningstar “made with organic”
Superburgers by Turtle Island
The Mother Jones blog post kicked up a lot of comments and questions and led Butler to do a follow-up interview with Vallaeys. The researcher points out that the hexane process is used to make many cooking oils, margarines, and other products. A key question of course, is whether residues from the hexane remain in the food—and Vallaeys concedes that more testing is needed in this realm.
But personally, I don’t need any more testing to convince me that using a gasoline ingredient to soak the fat out of vegetables is a bad idea, and to cut foods that use this process from my diet.

While the rest of us are freaking out about our veggie burgers, we might do well to get outraged on behalf of babies, too. Writes Butler:
More worrisome still: According to the report, “Nearly every major ingredient in conventional soy-based infant formula is hexane extracted.”
