Since 90% of soybeans in the U.S. are genetically modified, "traces" of proteinaceous material can be carried from soybean farm to soybean farm in the extraction process. The oil is, however, highly refined, effectively removing the proteinaceous matter along with the fatty acids, chlorophyll, off-odor and off-flavor components that are found in soybean oil. If any trace amount remains after that process, it would be so infinitesimal that it would require several gallons of oil to be submitted even to extract any DNA fragments. There is no DNA remaining at this point in processed oils, and when sent off for testing, the analytical report that is received from the GM testing/certification facilities will state that there is "no modified or conventional DNA present." That being said, our supplier cannot state that the oil is GMO-free since the testing results show that there was no modified or non-modified DNA present.
