Plant proteins are an important part of the human diet, but traditionally proteins from plants have not been purified.
Isolating the plant proteins and drying them into a shelf stable powder will give you new products with endless possibilities.
Pulses usually have a high content of protein, but also starch and fiber.
Other plant products, potato or grass have a lower protein content, but given the shear volume of grass you will have a vast good source. After purification and concentration the plant proteins can be spray dried giving you new types of proteins with interesting functionalities that can be used in human food or in animal feed.
