METHOD FOR EXTRACTING EXTRACT OF ANIMAL BONE, MEAT, ENTRAIL AND THE LIKE

摘要

PURPOSE:To obtain a concentrated extract without losing tasting components and nutriments nor causing the bad smell, by concentration broth of an animal bone, meat, entrail, etc., with a heating oil as a heating medium under two-stage vacuum conditions and separating the heating oil under reduced pressure conditions. CONSTITUTION:Bones, meat, entrails, etc., of an animal or fish or shellfish are boiled in hot water and the resultant broth is charged into a heating oil at a given temperature contained in a cooker. In the first stage, the broth is concentrated under a light vacuum degree of the interior of the cooker to coagulate and stabilize water-soluble proteins and gelatinuous materials in the animal fish or shellfish. The outflow of tasting components is prevented to carry to the concentration. In the next stage, the interior of the cooker is adjusted to a strong vacuum degree to carry out the concentration with prevented decomposition of nutriments and emission of bad small in a short time. The heating oil is then separated from the concentrated broth by the specific gravity difference under reduced pressure conditions to give the aimed concentration extract.
