Abstract:
A continuous direct protein solubilisation process of industrial waste of plant origin comprising:a) A first phase of successive washings of the waste with acidified water, at a pH range of 4-5.5, to wash out alkaloids including polyphenols, sugars and fibres, followed, in a continuous process by: b) A second phase of enzymatic reaction with endoproteases which attain a degree of hydrolysis which ranges from 25-40%, until obtaining, on one side, a liquid phase constituted essentially by solubilised peptones, at a concentration that ranges between 60-80% of the insoluble starting protein and which, subsequently, is filtered, sterilised, evaporated and concentrated to a powder, by conventional means, and on the other side, a solid phase constituted mostly by non-solubilised proteins, starches and insoluble sugars.
