Problems solved by technology

Experiments have proved that high-shear stirring is very effective in the production of phospholipid deoiling, but in the production of alcohol-soluble phospholipids, because the powdered phospholipid itself is solid, the application of this equipment is partially limited
However, if the phospholipids are prevented from agglomerating by controlling the ratio of material to liquid and the leaching temperature, it will undoubtedly restrict the requirements of the phosphatidylcholine content in the product on the process conditions, and the control of raw material moisture cannot effectively prevent agglomeration.
Once the raw materials are agglomerated, the leaching mass transfer will be affected, thus affecting the yield

Embodiment 1

[0011] Dissolve 100 grams of soybean powder phospholipids in 500 milliliters of n-hexane, add 200 grams of sand, and remove the n-hexane under stirring, so that the phospholipids are evenly coated on the surface of the dispersant. Then add 1000 milliliters of 95% ethanol, stir and leach at 50° C. for 70 minutes, filter, desolventize, and vacuum-dry to obtain alcohol-soluble phospholipids. The yield is increased by 4.1 times compared with that without adding dispersant.

Embodiment 2

[0013] Dissolve 100 grams of soybean powder phospholipids in 500 milliliters of n-hexane, add 100 grams of sand, and remove the n-hexane under stirring, so that the phospholipids are evenly coated on the surface of the dispersant. Then add 1000 milliliters of 95% ethanol, stir and leach at 50° C. for 70 minutes, filter, desolventize, and vacuum-dry to obtain alcohol-soluble phospholipids. The yield is increased by 4.04 times compared with that without adding dispersant.

Embodiment 3

[0015] Dissolve 100 grams of soybean powder phospholipids in 500 milliliters of n-hexane, add 300 grams of sand, and remove the n-hexane under stirring, so that the phospholipids are evenly coated on the surface of the dispersant. Then add 1000 milliliters of 95% ethanol, stir and leach at 50° C. for 70 minutes, filter, desolventize, and vacuum-dry to obtain alcohol-soluble phospholipids. The yield is increased by 4.2 times compared with that without adding dispersant.

Abstract

The invention provides a method for improving soybean alcohol-soluble phospholipid yield. According to the invention, 10g of soybean powder phospholipid is dissolved in 50ml of n-hexane; a dispersing agent, which is 400-mesh sand, is added; n-hexane is removed under stirring, such that phospholipid is uniformly coated on the surface of the dispersing agent; 95% ethanol is added according to a ratio that soybean powder phospholipid to 95% ethanol is 1:10 (W:V); stirring and leaching are carried out for 70min under a temperature of 50 DEG C; filtering and desolvation are carried out; and vacuum drying is carried out, such that alcohol-soluble phospholipid is obtained. Compared with a method in which no dispersing agent is added, a yield is improved by more than 4 times.

Description

technical field [0001] A method for increasing the yield of soybean alcohol-soluble phospholipids belongs to the technical field of phospholipids processing. Background technique [0002] In the production of soybean alcohol-soluble phospholipids, the alcohols reported at home and abroad mainly include C 1 -C 3 alcohol. When ethanol is used as a solvent, the results obtained by different researchers are quite different, which shows that the yield of alcohol-soluble phospholipids and the content of phosphatidylcholine in the product are all unstable. This indicates that there are many influencing factors in the preparation of alcohol-soluble phospholipids. This brings difficulties to the process control of industrial production when preparing alcohol-soluble phospholipids. Analyzing the reasons, the inventors believe that the leaching behavior of phospholipid raw materials is very important when low-carbon alcohols are leaching phospholipids. The phospholipids in the leac...
