The procedure is for obtaining pectin and uses vegetal raw material for use in the food industry, implicating hydraulic extraction, the hydro-module of the mixture being equal to 1:(3-4), with the aid of a cavitation procedure of the raw material containing pectin and water with a pH of 2-4 for 15 to 25 minutes, at a cavitation index of 0.2-1.9 and an excess pressure of 0.41-0.45 MPa in the extraction chamber of a hydro-acoustic disintegrated extractor. Subsequently, the pulp obtained is divided into liquid and solid phases in a centrifugal force field, the separation coefficient Fr being in the interval of 110-130 so that the content of suspended solids in the liquid phase is equal to or less than 0.1 per cent in relation to its mass. This liquid phase is concentrated by ultra-filtration at a pressure of 0.05-0.31 MPa, using ultra-filtration membranes. |
