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.
