Embodiment 1

[0018] Feed-grade concentrated soybean lecithin was used as raw material, 100g of raw material was taken, 100mL of petroleum ether / acetone mixed solvent was added (petroleum ether:acetone volume ratio was 2:3), mixed at 20°C for 60 minutes, and centrifuged to separate into solid and liquid phases. The solid phase was discarded, and the liquid phase was evaporated and precipitated under negative pressure at 70° C. and a vacuum of 0.096 MPa for 50 minutes to obtain a crude product (deproteinized concentrated phospholipid). The obtained product was dissolved in 1000mL petroleum ether / ethanol (petroleum ether:ethanol=1:1, v / v; ethanol is 40% ethanol aqueous solution) mixed solvent; Mixed 60 minutes under the condition of 30 ℃, liquid-liquid separation obtained light phase (petroleum ether phase) and heavy phase (ethanol phase). Add feed-grade concentrated soybean lecithin to the petroleum ether phase with 1.5% (m / m) H 2 o 2 Decolorize at room temperature for 30 minutes, then car...

Embodiment 2

[0020] Feed-grade concentrated soybean lecithin was used as raw material, 100g of raw material was taken, 800mL of petroleum ether / acetone mixed solvent was added (the volume ratio of petroleum ether:acetone was 5:1), mixed at 40°C for 30 minutes, after centrifugation, the solid phase was discarded, The obtained liquid phase was evaporated and precipitated under negative pressure at 75° C. and a vacuum of 0.095 MPa for 80 minutes to obtain a crude product (deproteinized concentrated phospholipid). Add 1500mL of petroleum ether / ethanol (petroleum ether:ethanol=1:4, v / v; ethanol is 70% ethanol aqueous solution) mixed solvent to the obtained product; mix at 50°C for 30 minutes, then carry out liquid-liquid separation , to obtain petroleum ether phase (light phase) and ethanol phase (heavy phase). Petroleum ether phase added feed grade concentrated soybean lecithin with 2% H 2 o 2 Decolorize at room temperature for 25 minutes, then carry out negative pressure evaporation at 80°C...

Embodiment 3

[0022] Using concentrated soybean oil lecithin for feed as raw material, add 100g of raw material into 1000mL of hexane / acetone mixed solvent (petroleum ether:acetone volume ratio is 1:2), mix for 60 minutes at 20°C, centrifuge, discard the solid phase, and the liquid The phase was evaporated and precipitated at 70° C. for 60 minutes under a vacuum of 0.096 MPa to obtain a crude product. Add the obtained product to 1000mL hexane / ethanol mixed solvent (hexane: ethanol solution=1:1, v / v; ethanol solution is 60% (m / m) ethanol aqueous solution), and mix for 60 minutes at 30°C, Liquid-liquid separation obtains hexane phase (light phase) and ethanol phase (heavy phase), and hexane phase adds feed grade concentrated soybean lecithin amount 1.5% (m / m) H 2 o 2 Decolorize at room temperature for 30 minutes, then carry out negative pressure evaporation at 70°C and a vacuum of 0.096MPa for 80 minutes; then dry (110 minutes) at 80°C and a vacuum of 0.098MPa to obtain food-grade concentrat...

Abstract

A production method of food grade condensed soybean phospholipid is characterized by comprising the following process flow: feeding grade soybean phospholipid is taken as a raw material, extracted by a mixed solvent of petroleum ether / acetone (or hexane / acetone), and centrifuged to obtain a liquid phase, and the liquid phase is evaporated at a negative pressure to remove the solvent; and a product with the solvent removed is extracted by a mixed solution of petroleum ether / ethanol(hexane / ethanol), and then is subject to liquid-liquid separation to obtain a light phase, and the light phase is decolorized with food grade hydrogen peroxide, evaporated at the negative pressure and dried in vacuum to obtain a food grade condensed soybean phospholipid product with light color and high transparency. The production method is characterized by using an organic solvent method to remove protein and saccharide affecting the transparency and the color in the feed grade condensed soybean phospholipid and resultants of a maillard reaction during the feed phospholipid processing procedures; and maintaining the original structure of phospholipid and keeping special flavor of the phospholipid. The used solvent is characterized by wide sources, low cost and easy removal; and the method is beneficial to improving the quality of phospholipid products and expanding the application of the phospholipid to the food industry and the medical industry.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of oil by-products—soybean lecithin processing, and in particular relates to a preparation method of food-grade concentrated soybean lecithin. Background technique [0002] Soybean lecithin is a by-product of hydration and degumming of crude oil in the process of soybean oil production. It is a lipid compound with important physiological functions and a natural surfactant. It is widely used in food, medicine, textile, leather, chemical industry, cosmetics and many other fields, and the market prospect is broad. [0003] The composition of concentrated soybean phospholipids is very complex, with phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylinositol (PI), phosphatidylserine (PS), phosphatidic acid (PA) and other phosphoglycerides as the main components. In addition, soybean phospholipids also contain some non-lipid components, such as phosphatidic acid, pro...
