METHOD FOR PREPARING PLANT RAW MATERIAL BEFORE PRESSING OUT JUICE Russian patent published in 2003 - IPC

FIELD: food industry. SUBSTANCE: the present innovation deals with treating raw material with liquefied gas at pressure being above atmospheric one and decrease of pressure to be equal to atmospheric one at rate to provide raw material's freezing. Before treatment, raw material is treated with preparation obtained due to successive extraction of Mortierella gemmifera micromycete biomass with nonpolar extragent in supercritical state with water, alkali, water, acid, water, alkali and water followed by combining solid residue with the first extract at the quantity of 0,5-1•10⁴ mg/t to be kept for 2-5 h. Moreover, one should apply ammonia gas for treatment. The suggested innovation enables to increase the quality of ready-to-use product. EFFECT: higher efficiency. 2 ex
