Problems solved by technology

Extract concentrated phospholipids with organic solvents to obtain powdered phospholipids. This method consumes a lot of organic solvents, and the product has residual organic solvents, which is harmful to the human body.
In addition, the supercritical fluid extraction method is used to purify phospholipids. This method requires high technical equipment, and the viscous properties of concentrated phospholipids cannot meet its requirements.

Embodiment 1

[0023] A kind of hydrated phospholipid prepared by soybean oil foot, adopts following method to make:

[0024] (1) Get the soybean oil bottoms produced by Shandong Zhongyang Biotechnology Co., Ltd. to process Meixi soybeans, add demineralized water and sulfuric acid and mix evenly in the reaction tank; the moisture content in the used raw material soybean oil bottoms is 32%, and the added demineralized water and The mass ratio of soybean oil bottoms is 0.69:1, and the mass of sulfuric acid added accounts for 0.3‰ of the mass of soybean oil bottoms. Heat the mixture to 85°C (the temperature difference does not exceed 1°C, and the heating rate is 2-5°C / min), keep it warm for 6 hours and perform chromatography. After the chromatography, keep the temperature of the material at 85°C, Centrifugation is carried out under certain conditions, and the obtained hydrated phospholipid enters the storage tank, and the water content in the obtained hydrated phospholipid at this time is 64%. ...

Embodiment 2

[0031] A kind of hydrated phospholipid prepared by soybean oil foot, adopts following method to make:

[0032] (1) Get the soybean oil bottoms produced by processing Brazilian soybeans by Shandong Zhongyang Biotechnology Co., Ltd., add demineralized water and sodium hydroxide and mix evenly in the reaction tank. The moisture content in the raw material soybean oil bottoms used is 36%, and the added demineralized water The mass ratio to soybean oil bottoms is 0.59:1, and the weight ratio of sodium hydroxide to soybean oil bottoms is 0.5‰. Heat the mixture to 75°C (the temperature difference does not exceed 1°C, and the heating rate is 2-5°C / min), keep it warm for 4 hours and perform chromatography. After the chromatography, keep the temperature of the material at 75°C. Centrifugation is performed and the resulting hydrated phospholipids enter storage tanks. The relationship between adding demulsifier sodium hydroxide and the yield of hydrated phospholipids is shown in Table 2....

Embodiment 3

[0039] A kind of hydrated phospholipid prepared by soybean oil foot, adopts following method to make:

[0040] (1) Get the soybean oil bottoms produced by Shandong Sanwei Oil Co., Ltd. to process American Gulf soybeans, add demineralized water and mix them evenly in the reaction tank. The moisture content in the used raw material soybean oil bottoms is 37%. The ratio is 0.57:1, and 0.2‰ sulfuric acid is added as a demulsifier. Heat the mixture to 85°C (the temperature difference does not exceed 1°C, and the heating rate is 2-5°C / min), then keep it for 4 hours for chromatography. After the chromatography, the material is heated to 95°C (the temperature difference does not exceed 1°C). , heating rate: 2-5°C / min), and then centrifuged. The relationship between the centrifuge speed and the oil output rate is shown in Table 3.

Abstract

The invention discloses a method for preparing hydrated phospholipid from soybean oil sediment and hydrated phospholipid prepared with the method, relates to the field of a treatment method of the soybean oil sediment and aims to solve the problems that with adoption of the conventional soybean phospholipid refining method, organic solvent consumption is high and many residues are produced and are harmful to a human body or the prepared soybean phospholipid is strong in flavor, dark in color and low in quality. According to the method, softened water is added to the soybean oil sediment, then the soybean oil sediment is left to stand for chromatography, heating is performed after chromatography for centrifugal separation, and hydrated phospholipid is obtained. Acetone insoluble substances in the prepared hydrated phospholipid can reach 90% or higher, the phospholipid content is higher, and organic matter residues are avoided.

Description

technical field [0001] The invention relates to a treatment method for soybean oil bottoms, in particular to a method for preparing hydrated phospholipids from soybean oil bottoms and the prepared hydrated phospholipids. Background technique [0002] Phospholipids are widely found in animals and plants, especially in the brain cells of animals. Phospholipids are ubiquitous in human cells and are essential substances to ensure normal metabolism and health of the human body. In addition to controlling the transmission of substances and information inside and outside the cell membrane, they also have a certain regulatory effect on the activity of membrane function-related enzymes. Unsaturated fatty acids in soybean phospholipids can improve the function of biofilm, increase the fluidity of biofilm, and reduce the incidence of atherosclerosis. It plays an important role in the activation and survival of human cells, the maintenance of organ functions, the vitality of muscles an...
