Continuous direct enzymatic protein solubilisation process for industrial waste. The invention consists of obtaining peptones (mixture of proteins, peptides and amino acids) starting from industrial wastes of plant origin. The process is carried out in two steps. On the first step the wastes are subjected to successive washes with acidified water to wash out alcaloids (polyphenols), sugars, insoluble fibres, etc., a concentrate rich in proteins being obtained. In a continuous process said protein concentrate is next subjected to a second enzymatc hydrolysis step (25-40%) with endoproteases, the peptones being obtained which involve a degree of solubilisation in the order of 60-80% of the insoluble commencement proteins.
