Embodiment 1

[0057] A kind of preparation method of powder phospholipid, with reference to attached figure 1 And attached figure 2 , including the following steps:

[0058] (1) Hydration: Add soybean oil feet into water, break up the oil feet in the water into granules by stirring, and form an immersion system with soybean oil feet particles as the dispersed phase and water as the continuous phase. The soaking temperature is 60°C , soaking time is 3h, get saturated water-absorbing oil feet. The saturated water-absorbing oil foot is marked by the appearance of brown self-aggregated water-containing phospholipids.

[0059] The soybean oil foot comes from COFCO Jiayue (Tianjin) Co., Ltd., and its material composition: the water content is 41.03g / 100g, the dry base acetone insoluble matter content is 61.13g / 100g; the water is drinking water; the oil foot The mass ratio to water is 1:1; the particle diameter of the oil foot particles is 0.3-3mm.

Abstract

The invention belongs to the technical field of phospholipid processing, and in particular relates to a preparation method of powdered phospholipid. The preparation steps include soaking soybean oil feet in water and natural sedimentation to obtain self-aggregated phospholipids. The self-aggregated phospholipids are concentrated, stirred, and continuously dried to obtain solid phospholipids, and then pulverized, sieved, and dried to obtain powdered phospholipids. The content of acetone insolubles Reaching 92.5‑95.5g / 100g, the color is natural yellow, solvent-free and non-bleaching. The invention solves the problems of low phospholipid content, deep color, long drying time and lack of industrial feasibility in the existing hydration method powder phospholipids; it can replace the preparation method of solvent method powder phospholipids to eliminate the pollution of solvents to the environment. Food safety hazards caused by residues, and reduce production costs; and use the physical method of stirring to change the color of the object to eliminate food safety hazards caused by chemical bleaching.

Description

technical field [0001] The invention belongs to the technical field of phospholipid processing, and in particular relates to a preparation method of powdered phospholipid. Background technique [0002] The raw material for phospholipid processing is soybean oil foot, referred to as oil foot, which is a by-product of the hydration degumming process in the soybean oil refining process in the field of oil processing, also known as hydration oil foot, and its main components are phospholipids 30-45g / 100g, 20-30g / 100g of soybean oil and 30-50g / 100g of water, the trace components are metal ions, such as calcium, magnesium and iron, etc., which exist in the form of phospholipid metal salts, such as iron ion content, usually 50% in terms of acetone insoluble matter -100mg / kg, in individual cases as high as 150mg / kg or more. [0003] There are two main industrial phospholipid processing methods. One is the hydration method to prepare concentrated phospholipids, that is, after hydrat...
