FIELD: food industry.SUBSTANCE: invention relates to production of paste-like semi-finished products of fruit and vegetables. For production of paste-like semi-product from fruit and vegetable the raw material passes sequential 2-stage treatment with water with temperature of 25-35°C and pressure of 2-3 Pa, generated in viabrating washing machine during 2-8 minutes and water or steam of temperature 96-98°C for 8-12 minutes, and centrifugation of residual water between the stages, peel and non-edible parts removal from the raw material, then milling into particles sized max. 1 mm with further mixiing with liquid component at temperature of 40-45°C to obtain a mixture with moisture of 75-90%, with subsequent treatment in conditions of combined action of hydrodynamic and acoustic cavitation in mutually perpendicular planes, with frequency of oscillations 18-24 kHz and amplitude of oscillations of 1-3 microns, cavitation is performed to achieve stable mass with particle size of solid phase max. 10 microns and uniformity of distribution of components 90-92%, with further drying up to humidity 40-60%, removal of oxygen under vacuum rarefaction at 5-7 Pa (0.00005-0.00007 ATM) and aseptic packaging into sterile packages or small containers. Besides, the liquid component is represented by water or fat or invert syrup or molasses.EFFECT: method enables production of semi-finished product at low power consumption with high dispersion, preservation of vitamins and microelements.2 cl, 2 ex |
