Abstract
A process is provided for encapsulating glutathione (GSH), 3,3′-diindolylmethane (DIM), coenzyme-Q10 (CoQ10), and other hydrophobic antioxidant compounds by using whey proteins which may be polymerized in a particular manner. Further, compositions comprising polymerized whey protein (PWP) encapsulated glutathione, polymerized whey protein (PWP) encapsulated CoQ10, and polymerized whey protein (PWP) encapsulated DIM are provided.
Claims5
A process for making a polymerized whey protein concentrate microencapsulated glutathione, the process comprising the steps of:
- (a) dissolving a powder of whey protein concentrate (WPC) in deionized water at room temperature to provide a WPC aqueous solution, wherein the WPC is present at concentration of 10 w/v %;
- (b) adjusting pH of the WPC aqueous solution to 7-8 and heating said WPC aqueous solution to about 70-80° C. for about 15 minutes;
- (c) cooling the heated WPC aqueous solution to room temperature to provide a polymerized WPC solution;
- (d) adding glutathione powder to the polymerized WPC solution to provide a mixture;
- (e) stirring the mixture to achieve complete dissolution and to provide a clear homogeneous solution;
- and
- (f) isolating the polymerized WPC microencapsulated glutathione by freeze-drying or spray-drying to provide a powder.
