This disclosure relates generally to lupin protein, and more specifically to modifying lupin protein to improve its use as a protein feedstock, for example in food processing. Provided herein is a method of forming a protein feedstock comprising modified lupin protein that has a decreased thermal stability compared to unmodified lupin protein, the method comprising providing a solution of lupin protein, passing ultrasound waves through the solution of lupin protein in a manner to form the modified lupin protein and collecting the modified lupin protein. Also provided is a protein feedstock comprising modified lupin protein, the modified lupin protein having a decreased thermal stability compared to unmodified lupin protein, wherein the modified lupin protein is formed by subjecting unmodified lupin protein to ultrasound waves, as well as compositions and food products comprising the protein feedstock.

A method of harvesting plant product from a plant in a single pass using a combine harvester is disclosed. In the method, the plant has a protein content gradient that varies along a height of the plant. The method includes identifying, along a longitudinally-extending stalk of the plant, an upper protein gradient of the plant including high protein plant product and a lower protein gradient of the plant including lower protein plant product, wherein the high protein plant product from the upper protein gradient of the plant meets a threshold protein content that is higher than that of the lower protein plant product. The method also includes separately and substantially simultaneously harvesting the high protein plant product from the upper protein gradient and the lower protein plant product from the lower protein gradient in the single pass, and isolating the high protein plant product from the lower protein plant product.

This invention relates generally to methods for increasing bioactivity of lunasin in liquid formulations, sonicated bioactive lunasin compositions and methods of using sonicated bioactive lunasin. More specifically, this invention relates to methods of increasing bioactivity of lunasin in liquid formulations by administering sonication. One embodiment the present invention provides a method of increasing the bioactivity of lunasin comprising: a) providing a composition comprising lunasin, b) putting said composition into solution, and c) administering sonication to the composition.

A method for producing a clean-tasting, neutral-color, concentrated, liquid protein base including separating fibrous material from the protein base. The method further includes applying ultrasonication to the protein base at an ulirasonication unit according to ulirasonication settings. The ultrasonication settmgs are adapted to cause acoustic cavitation within the protein base. The method further includes filtering the protein base through one or more membrane filters after separating the fibrous material from the protein base. The method further includes processing the protein base to form a protein ingredient in certain cases, the method further includes processing the separated fibrous material to produce a dietary fiber. Processing the fibrous material includes converting gelatinized starch from the separated fibrous material into resistant starch.
