Title:
FRACTIONATING METHOD FOR MILK OR DAIRY PRODUCT AND EXTRACTIVE FRACTION
Document Type and Number:
Japanese Patent JPH04135452
Kind Code:
A
Abstract:
PURPOSE: To obtain fractions such as fats, inorg. matters, nonprotein nitrogen fraction and lactose by extracting a dried milk or dairy product with a carboxylic acid soln. and separating a solid residue from a liquid extract. CONSTITUTION: Dried milk or diary product (having 0 to 15wt.%, preferably 0 to 8wt.% water content) is extracted with a soln. containing 40 to 100wt.% preferably 85 to 100wt.% carboxylic acid (which may contain hydroxy or oxo groups, and preferably which is acetic acid, propionic acid and glycol acid) at 15 to 100 deg.C, advantageously at about 15 to 50C. The extract is separated from the solid residue by tilting, filtration by sucking, centrifugal separation, ultrafiltration, etc. from the liquid extract, fats, inorg. matters, nonprotein nitrogen component and riboflavin are obtd., while from the solid residue, casein, whey protein, lactose, etc., are obtd.
