The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
Seed storage protein. Not integrated in the gluten polymer through disulfide bonds, unless incorporated by reduction and reoxidation during dough making. Increases dough strength and bread volume, but decreases dough stability when added into a base wheat flour (By similarity).
