Problems solved by technology

However, because the phospholipids produced are in the form of fine powder particles, they are easy to combine into agglomerates or lumps. In addition, the drying method used in the production process is the double-cone drying method, which consumes a lot of energy. Heating and vacuum drying require heat energy and take a long time. One 135L The maximum output of double cone drying is about 90Kg at one time. Manufacturers with large output need to install several same equipment at the same time, which requires a large investment and many people. In addition, the product cost is high, and the color and quality are not good.

Embodiment 1

[0012] The raw material used in the present invention is milky phospholipid prepared from alkalized or hydrated soybean oil bottoms, the extraction solvent is acetone, first according to the ratio of milky phospholipid: acetone=1: 10 parts by weight, acetone is pumped into the stirring extraction tank, Turn on the stirrer (stirring speed is about 80 rev / min), pump in milky phospholipid while stirring, and stir continuously for 0.5h. Stop stirring and let the layers rest. The upper layer liquid is released, and the amount of acetone used for the second, third, fourth, and fifth extractions is respectively 5, 5, 5, and 2 times the weight of the milky phospholipid raw material. The stirring and extraction time is the same as above, and precipitation occurs. If fresh hydrated oil feet are centrifuged and dried, they can become powdered phospholipids, but if the raw material is milky phospholipids produced from alkalized oil feet or milky phospholipids processed from hydrated oil f...

Embodiment 2

[0016] The present invention adopts the milky phospholipid that the raw material is the preparation of alkalized or hydrated soybean oil bottoms, and the production process is the same as embodiment 1, and the difference is that adding cellulose diacetate or cellulose acetate or cellulose triacetate and passing through After centrifugation, it is dried by vacuuming and recovering acetone at a low temperature of 10-30°C. The color and quality of the product thus obtained are good. However, powdered phospholipids produced at low temperature should be packaged immediately because they are easy to absorb moisture. This process is also suitable for the production of powdered phospholipids from rapeseed and peanut milky phospholipids.

Embodiment 3

[0018] The present invention adopts the milky phospholipid that the raw material is prepared from alkalized or hydrated soybean oil bottoms, and the production process is mostly the same as in Example 1, except that cellulose diacetate or cellulose acetate or cellulose triacetate is added And after centrifugation, drying can also be carried out at a temperature above room temperature, and it can be dried naturally under sunlight at about 35°C, and the effect is also very good. If heated and dried, it should be controlled and must not exceed 55°C, otherwise the phospholipids added with cellulose diacetate, cellulose monoacetate or cellulose triacetate will easily burn when dry, and the color will easily turn brown and black, sticky and difficult to form powder. This process is also suitable for the production of powdered phospholipids from rapeseed and peanut milky phospholipids.

Abstract

The invention provides a new process for producing powdered phospholipids using alkalized milky phospholipids produced from alkalized oil bottoms of different plants such as soybeans, peanuts or rapeseeds. Add it into the extractor, then add milky phospholipid under stirring, stir and extract, let stand, and then extract the precipitate with acetone continuously under stirring until the supernatant is roughly colorless and clear, release the acetone extract located on the upper part of the precipitate, and then Then add a small amount of cellulose acetate, stir to dissolve, and centrifuge and dry the phospholipid powder to obtain powdered phospholipid after the phospholipid powder is suspended. The cellulose acetate is cellulose acetate, cellulose diacetate or cellulose triacetate; the addition amount is cellulose acetate:dry powdered phospholipid=1:1000-10000 parts by weight.

Description

technical field [0001] The invention relates to a new process for producing powdered phospholipids, in particular to a new process for producing powdered phospholipids using alkalized milky phospholipids produced from alkalized oil feet of different plants such as peanuts, soybeans, and rapeseeds as raw materials. Background technique [0002] The solvent used to extract and prepare powdered soybean lecithin is acetone, and there are many reports on the known technology, such as "Refining of Medicinal Soybean Lecithin" published in Journal of Veterinary University. 13 (4) 372-375.1993. Food Industry Technology (7). 18~23.1990 published "the production method of new high-quality soybean lecithin", proposed to prepare powdered soybean lecithin with ether-acetone-water method to remove oil, and the fractionation of ether-acetone is relatively complicated. "Solvent method refinement and separation of phospholipids" announced by China Oils and Fats. 10 (3). Then there is one mor...
