A process for producing microencapsulates comprising an active component such as creatine encapsulated within a polymerised hydro lysed whey protein matrix is described. The method comprises the steps of providing a suspension of hydro lysed whey protein and an active component in a carboxylic ester, treating the suspension to generate droplets of the suspension, and immediately curing the droplets by immersion in a basic curing solution, wherein the ester in the suspension reacts with the basic curing solution to release a salt that polymerises the hydrolysed whey protein encapsulating the active component in the presence of black pepper extract, glycerol, phosphate and optionally, astaxanthin and alpha lipoic acid.
