Extracting & Purifying

Once the plants are harvested, an extraction process is performed that is similar to juicing, or squeezing out every drop of fluid from the plants. This 'green juice' contains human recombinant Intrinsic Factor (rH-IF) as well as many other plant proteins. None of the plant material is harmful, because it is from an edible plant of the mustard family, but nevertheless, this plant material is removed by a series of purification steps that delivers a highly purified liquid containing IF. The liquid extract is then either freeze dried for use in pharmaceutical drug delivery applications or diagnostic tests, or is converted into a powder form for use as an ingredient beverages, nutritional supplements and other food products.
