SUBSTANCE: method includes sorting, washing, ageing the roe membranes in brine, its treatment by brine with following addition of ferment, and caviar separation and its salting. Roe membranes are aged in brine for 0.5-15 min at temperature 0-20 C with simultaneous treatment by ozone. Brine is separated, roe membranes are placed in device with perforated basket and mixer, and brine with concentration of sodium chloride 2.5-10% is added at temperature 36-45 C. Ferment is prepared at equalling of temperature between row membranes and brine till concentration of 5-100 mg/l; caviar is separated, and its washing is carried out by solution of sodium chloride with concentration of 2.5-10% at temperature 0-20 C passing it through a caviar layer 2-5 times. Salting is carried out in brine with temperature 0-(-15) C with simultaneous treatment by ozone. EFFECT: preparation of ecologically clean product. 2 exps |
