Low iron hydrous phospholipid and method for separating low-iron hydrous phospholipids from soybean oil sediments

Abstract

The invention belongs to the technical field of phospholipid processing, in particular to a low-iron hydrous phospholipid and a method for separating low-iron hydrous phospholipids from soybean oil sediments. The main components of low-iron water-containing phospholipids are phospholipids, oil and water; its water content is 70-80 g/100 g; on a dry basis, the content of acetone-insoluble matter is 92.5-95.5 g/100 g; in terms of acetone-insoluble matter, the iron content is less than or equal to 18 mg/kg. The low-iron water-containing phospholipid of the present invention is prepared from soybean oil by a hydration method, and is used to solve the defects of low acetone-insoluble content of the water-containing phospholipid, inability to remove iron ions and the industry's long-term dependence on the solvent method to prepare the powdered phospholipid; At the same time, the method solves the technical problem that “the preparation of powder phospholipid by hydration method cannot realize industrial production”.
