METHOD FOR PREPARING OF RAW PLANT MATERIAL FOR JUICE SQUEEZING Russian patent published in 2003 - IPC

FIELD: food-processing industry. SUBSTANCE: method involves impregnating raw plant material with liquefied gas under pressure above atmospheric pressure and releasing pressure to value equal to atmospheric value at rate providing freezing of raw plant material; before impregnation procedure, treating raw plant material with preparation produced by sequential extracting of Mortierella exigua micromycet biomass with the use of non-polar extractant in above-critical state, water, alkaline, water, acid, water, alkaline, and water, with following joining of first extract with solid residue and holding for 2-5 hours, said preparation being used in an amount of 0,5-1•10⁴ mg/t. Ammonia is used as impregnation gas. EFFECT: improved organoleptical properties due to elimination of opalescence.
