TVP (Textured Vegetable Protein)is an excellent protein source that is easy to store and use. TVP is made from soy flour where the soy oil has been extracted. It is cooked under pressure and then extruded and dried. Not only is TVP high in protein, but its also high in fiber and low in fat. This makes TVP ideal forfood storage and also for every day use. Because TVP is not made from meat, it does not have the contamination risk that many meats have with bacteria such as E. Coli and Salmonella. Because it is soy based, it is perfect for those on a vegetarian diet.
TVP is very shelf stable and can sit in a sealed container for at least a year. When sealed in an airtight container (where the oxygen has been removed) the shelf life is much longer. TVP is best stored in a cool, dry place
