The present invention provides a walnut oligopeptide powder, a preparation method and application thereof. The oligopeptide powder has a peptide content of 80 wt % or higher, in which 95% or more of the peptides have a molecular weight of less than 1,500 Da. The method includes extracting walnut proteins using a highly efficient countercurrent extraction process, and subjecting the extract to filtration, enzymolysis, purification with a microfiltration membrane and an ultrafiltration membrane, concentrating, and spray drying to obtain the oligopeptide powder. The oligopeptide powder has an anti-oxidant activity and provides a protective effect for a neuron, and thus can ameliorate or treat memory deterioration and relieve fatigue.

A preparation method and an application of sea cucumber protein peptides are disclosed. The disclosure develops a preparation method of sea cucumber protein peptides with simple operation and excellent product quality by optimizing raw materials and enzymolysis extraction process of sea cucumber protein peptides. On the one hand, the problem that the deodorization and decolorization effect of the sea cucumber peptide hydrolysate of the prior art is not obvious is solved. On the other hand, the obtained sea cucumber protein peptides can be processed into nutritional supplements and used as raw materials for preparing health care products or cosmetics for enhancing immunity, relieving physical fatigue, resisting oxidation and aging, which has good development and utilization potential.

A dry fractionation method and system provides for generating a protein concentrate product therefrom. The method and system includes milling a plant-based flour to generate milled flour and generating a first protein concentrate from the milled flour using an air classifier. The method and system includes processing the first protein concentrate to generate a protein rich curd and generating a neutral hydrolyzed protein slurry by mixing the protein curd with a base, water and enzymatic cocktail. The method and system includes generating a homogenized protein slurry from the protein slurry and generating a cooled protein slurry by pasteurizing the homogenized protein slurry. Therein, the method and system provides for extracting the protein concentrate product from the cooled protein slurry.

The present invention relates to a protein bar that is formed from a moldable mixture containing proteins and/or protein hydrolysates. The moldable mixture contains a collagen hydrolysate having an average molecular weight of up to 1,700 Da as a protein hydrolysate.

The present disclosure discloses methods for preparing plant-based protein compositions, such as a pea protein isolate, comprising alkaline phosphate salts, wherein the compositions exhibit greatly improved solubility.
