Powdered nutritional products containing branched-chain amino acids and a sugar alcohol are provided. The branched-chain amino acids in the powdered nutritional product exhibit improved solubility and thus improved dissolution upon reconstitution of the powdered nutritional product.

The invention concerns a process for the treatment of a sweet whey material containing cGMP (caseinoGlycoMacroPeptide), said process comprising the following steps: —Decationising the sweet whey material so as to obtain sweet whey material having a pH value of 1 to 4.5; —Treating said sweet whey in a fluidized bed reactor comprising a specific volume of an anionic resin, at a temperature between 10 and 18° C., wherein said sweet whey contacts said resin for a sufficient amount of time so that the resin absorbs between 52% and 58% of the cGMP present in the sweet whey; and—Recovering a protein material. Advantageously, the protein material is suitable for hypoallergenic infant formulae.

The invention relates to a peptide isolate isolated from a biomass of protein-rich microalgae, characterized in that it comprises: soluble peptides with a molecular weight of between 1 and 20 kDa, a protein content expressed as N.6.25 of more than 95%, essentially arginine and glutamic acid.

The invention relates to a method for fractionating the components of a biomass of protein-rich microalgae of the genus Chlorella, characterized in that it comprises the following steps: providing a microalgal biomass produced by fermentation, optionally, washing the biomass so as to eliminate the interstitial soluble compounds, thermal permeabilization of the biomass at a temperature of between 50 and 150° C., preferably 100 and 150° C., for a duration of between 10 seconds and 5 minutes, preferably for a duration of between 5 seconds and 1 minute, separation between the biomass thus permeabilized and the soluble fraction by a centrifugation technique, more particularly multistage centrifugation, optionally, recovery and clarification of the soluble fraction obtained in this way by microfiltration so as to remove residual insoluble substances therefrom, separation of the preceding soluble fraction by precipitation, so as to obtain a peptide isolate and a peptide concentrate.

A process for producing an arginine-rich peptide mixture and the application thereof in cervical cancer therapy is provided. The process includes the following steps: A suspension of walnut meal and egg albumin is pretreated with ultrahigh pressure, and then digested by alkaline proteinase and papain in separated steps with the ultrasonic and microwave-assisted extraction. The peptides of interest are isolated from filtration supernatant obtained after the enzyme digestion by reversed phase high-performance liquid chromatography. By using the peptide mixture as a template, acrylic acid and methyl acrylic acid as functional monomers, triethylene glycol dimethacrylate as cross-linking agent, and isopropylthioxanthone in acetone as a photoinitiator, polymerization is induced by ultraviolet light to form a surface imprinted membrane for isolating and enriching the peptides of interest from the supernatant. The arginine content in the peptide mixture is more than 18%. The arginine-rich peptide mixture is able to strongly suppress the proliferation of human cervical cancer Hela cells. The approach is applicable to reduce the cost of production and speed up the commercialization of large-scale production.

The present invention relates to use of peptides as a therapeutic agent, wherein it has been confirmed that the peptides of the present invention significantly inhibit the activity of T cells and the differentiation of T helper 17 cells (Th17 cells), which are associated with autoimmune disease, and have remarkable effects of treating and improving arthritis in an animal model of arthritis. Therefore, the peptides may be used as an active ingredient in therapeutic agents for various autoimmune diseases such as bone disease, inflammatory disease or rheumatoid arthritis.

A method to prepare a mixture to make cereal-based food products which natively contain gluten includes a step of mixing cereal flour and a step of preparing a mixture obtained by mixing a hydrolyzed flour composition with a transglutaminase enzyme and with a source of lysine.

The present invention relates to a novel use of milk exosomes, and more specifically, provides various uses of milk exosomes, such as in functional cosmetics, functional health food with various functions such as improving gut health and immunity, and drugs including a wound healing medication.
