Abstract: The present invention provides a method of producing a protein-based encapsulate, said method comprising: providing an aqueous solution of a protein that is capable of forming disulfide cross-links; submitting said aqueous solution to a protein activation treatment to produce an aqueous suspension of activated protein aggregates, said suspension having a reactivity of at least 5.0 ?mol thiol groups per gram of activated protein aggregates as determined in the Ellman's assay; dispensing said aqueous suspension in a gas or a water-immiscible liquid to produce suspension droplets having a diameter of 0.1-500 ?m; and forming disulfide cross-links between the activated protein aggregates by contacting the activated protein aggregates with an oxidizing agent, optionally after said activated protein aggregates have been partially cross-linked by forming disulfide cross-links by means of heat treatment or by pressurization to a pressure in excess of 50 MPa.

Abstract: The invention provides an encapsulate comprising a protein-based encapsulation matrix that envelops one or more oil droplets containing at least 3 wt. % of polyunsaturated fatty acids (PUFAs) by weight of oil; said encapsulate having a mass weighted average diameter in the range of 0.5-5000 ?m, wherein the protein-based encapsulation matrix contains at least 10 wt. % of a protein that has been cross-linked by means disulfide cross-links, said protein-based matrix further being characterized in that: i. less than 75 wt. %, preferably less than 40 wt. % of the protein contained in the protein-based matrix can be dissolved when 75 mg of the encapsulate is dispersed in 50 ml distilled water having a temperature of 5° C. at any pH within the range of 3.0-7.0; ii. the weight percentage of the protein that can be dissolved is at least a factor 1.3 higher when in the procedure under i) the distilled water is replaced by an aqueous solution of 2 wt. % dithiothreitol (DTT).

Abstract: Particles that are encapsulated by protein are provided. Also a method for preparing protein encapsulated particles involving spraying and drying of an activated protein solution is provided. The protein encapsulated particles are particularly suited for food, feed, cosmetic and pharma applications.

Abstract: A method is presented for producing a casein/caseinate hydrolysate stripped of immunogenic proteins. The method comprises treating an aqueous solution, such as milk, comprising casein/caseinate and immunogenic protein other than casein with a protease that selectively hydrolyzes casein. After the casein/caseinate has been hydrolyzed, the casein/caseinate hydrolyzate is separated by membrane ultrafiltration from unhydrolyzed immunogenic protein and recovered. The resulting hydrolyzate is essentially free of antigenic components of the ABBOS peptide and bovine serum albumin. The casein selective protease is selected from cell wall proteinase of Lactococcus lactis subsp. Cremoris Wg2, a Clostridium histolyticum collagenase and a Bacillus polymyxa dispase.

Abstract: A method for the selective hydrolysis of casein/caseinate in the presence of at least one further protein constituent other than casein/caseinate, the casein/caseinate and the at least one further protein constituent being brought into contact with a proteolytic enzyme under conditions for the hydrolysis of the casein/caseinate, characterized in that the casein/caseinate and preferably also the at least one further protein constituent are in an essentially dissolved state, and in that a proteolytic enzyme is a proteinase specific for casein/caseinate, such that the casein/caseinate is hydrolysed while the further protein constituent remains essentially intact. This method can be used, in particular, for the preparation of a hydrolysed casein preparation or alternatively for the preparation of a milk protein preparation, in particular, a whey protein preparation which has been stripped of casein/caseinate.
