Description
Technical field
The present invention relates to produce the method for powder lecithin, the alkalization emulsus phosphatide that especially a kind of alkalization oil foot that utilizes different plants such as peanut, soybean, vegetable seed is made is the method for the Powdered phosphatide of raw material production.
Background technology
Extract preparation powder soybean phospholipid solvent for use and be the existing many reports of acetone (Zhao Yingju etc. medicinal soybean lecithin refining. animal doctor's college journal .13 (4) 372-375.1993).Tong Qigen (production method of novel high quality soy phosphatide, foodstuffs industry science and technology (7) .18-23.1990) proposes with ether-when the acetone-water method prepares the powder soybean phospholipid except that deoiling, and the fractionation relative complex of ether-acetone.Ni Hongzhi (solvent method of phosphatide is refining and separates. Chinese oil 10 (3) .50-52.1991) propose with the yield that can increase substantially phosphatide after the acetone oil removing once again with water treatment, but more than having dewatered then during again with acetone extract a dewatering process.The phosphatide color and luster is dark when using acetone deoiling once more, and the acetone consumption does not reduce.Wang Jingshi (preparation of soybean phospholipid and application. chemical and bonding. (1) .1991.36-40) with 5 ℃ of acetone extraction powdered soybean phospholipids,, but must have freezer in process of production because this moment, solubleness was 0.003%.Temperature light source etc. (the reparation technology experiment of powder soybean phospholipid. Chinese oil 1985 (5) .40-47), Zhang Genwang etc. (development of human consumption soybean phosphatide. Zhengzhou Grain College journal 1991 (2) .1-8) carry out powder soybean phospholipid pilot experiment with acetone as solvent, spray strip device and the circulation device except that the latter increases a material separating disc at stirring feed solution mouth, other parts of technology do not have big-difference.But the two all makes raw material with soybean aquation concentrated phosphatide.Up till now, making raw material in China with soybean aquation concentrated phosphatide adopts acetone extract explained hereafter powder lecithin to be accepted by producer.But now the above grease of China 90% factory takes alkali addition process.Alkalization oil foot or by its alkalization emulsus phosphatide that is processed into, perhaps the emulsus phosphatide producer of hydrated oil foot preparation has added alkali therein for reducing acid number.It is then very difficult to adopt above production technique to make powder soybean phosphine fat.Saponified and the normal phosphatide of glyceride can not form powder when mixing oven dry.Utilizing the alkalization oil foot to prepare the powder soybean phospholipid is to require study and the wide new technology of market outlook.Liu the present inventor obviously improves with alkalization emulsus phosphatide production powder lecithin effect for the powder lecithin working system that becomes once to have invented a kind of suitable different plant emulsification phosphatide raw materials (Chinese patent application number be 200310105345.5).About 1 ton 500 yuan of alkalization oil foot prices, the about 1 ton of 2000-2500 unit of the alkalization emulsus phosphatide that is processed into thus, and 1 ton/3000-4000 of aquation emulsus phosphatide price unit.
Summary of the invention:
The purpose of this invention is to provide and a kind ofly just utilizing the solvent acetone emulsus phosphatide that will alkalize to be extracted to the roughly water white front and back of supernatant liquor and to add the processing aid that is beneficial to powdered phospholipid production, make alkalization emulsus phosphatide raw material production powder lecithin easier, the more effective technology that becomes simple, the method for easy handling.
Purpose of the present invention can realize by following technical measures
Earlier with the proportioning adding extraction container of acetone according to alkalization emulsus phosphatide and acetone, add alkalization emulsus phosphatide down in stirring again, stir extraction, leave standstill, when again throw out being extracted to the supernatant liquor water white transparency continuously with acetone under stirring, getting the precipitated liquid that contains powdered phospholipid and be sent from scheming, the phosphatide after centrifugal is joined to be dissolved with according to dry powder phosphatide amount be in the mellisic acetone solution of 100 0.01～0.1 weight part, under agitation be cooled to normal temperature, centrifugal drying gets powder lecithin.
The described temperature that is dissolved with the mellisic acetone solution is 50-55 ℃.
The alkalization emulsus phosphatide that the present invention adopts the alkalization oil foot to make is that the raw material production powder lecithin not only greatly reduces production cost, and the separation of solvent in convenient the production, do not need other auxiliary processes and equipment, just utilizing the solvent acetone emulsus phosphatide that will alkalize to be extracted to the roughly water white front and back of supernatant liquor and to add the processing aid that is beneficial to powdered phospholipid production, make alkalization emulsus phosphatide raw material production powder lecithin become easier, more effective, cost is lower.
Embodiment:
Embodiment 1
It is the emulsus phosphatide (moisture do not surpass 2%) of alkalization soybean oil residue preparation that the present invention adopts raw material, the extraction solvent is an acetone, earlier by alkalization emulsus phosphatide: the weight part proportioning of acetone=1: 10, acetone is pumped into the stirring extractor, begin to stir, stirring velocity 80r/min pumps into alkalization emulsus phosphatide (pressing 10Kg/min speed) while stirring.Stir extraction 0.5 hour behind the intact alkalization of the pump emulsus phosphatide, stop to stir, static avaling 15 minutes emitted supernatant liquid.Second and third, extract used amounts of acetone for four, five times and be respectively 5,5,5,2 times of alkalization emulsus phosphatide parts by weight of raw materials, stir the extraction time and static, sinking time is same as described above.During the supernatant liquor water white transparency, the precipitated liquid that contains powdered phospholipid under agitation can be emitted and adds whizzer, centrifugal (1400r/min) 5 minutes by extractor to the end.Phosphatide is the powder agglomates shape, then it being joined 50 ℃ is dissolved with the mellisic acetone soln (the beeswax amount is a dry powder phosphatide: beeswax=100: 0.01 weight parts), stirred 10 minutes, evenly, be cooled to normal temperature while stirring, static, avale, emit the supernatant acetone solution after, stir and to emit the precipitated liquid that lower floor contains powdered phospholipid, centrifugal (1400r/min) 5 minutes down, be paved into 1cm thickness, dried 15 minutes for 55 ℃, or adopt the dry 30 ℃ of dry powdereds of vacuum of bipyramid, packing then.The content of soybean composite phospholipid in powder lecithin is generally about 95%.
