Abstract
The present invention discloses a multi-step coupling method to prepare concentrated phospholipids with a high transparency, which belongs to the technical field of soybean phospholipid production. The feed-grade concentrated phospholipids are used as raw materials, and the raw materials are dissolved in normal hexane or other non-polar solvents, are subjected to pre-impurity removing by centrifugation, precisely filtrated, bleached by food-grade hydrogen peroxide, are subjected to adsorption treatment and other multi-step coupling processes to obtain soybean concentrated phospholipids which contain normal hexane insoluble substances less than 0.05%, and are high in transparency and light in color and luster. By using precisely filtration and other technology, a new technology condition which uses feed-grade phospholipids as raw materials to produce food-grade soybean concentrated phospholipids is established, and the concentrated phospholipids can be industrially produced in a large scale. The preparation method solves the technical problems that the soybean concentrated phospholipids are high in impurity content and poor in transparency in our country, and each indicator of the prepared soybean transparent concentrated phospholipid product reaches or is above the national standards.
Description
Technical field
The present invention relates to the method that high grade of transparency concentrated phosphatide is prepared in the coupling of a kind of multistep, belong to soybean lecithin production technical field.
Background technology
Phosphatide is mainly derived from the vegetalitas oil plants such as soybean, and soybean lecithin is the product that the accessory substance in crude oil of soybean hydration degum production process obtains after processed.Phosphatide mainly comprises: phosphatid ylcholine (PC), phosphatidyl-ethanolamine (PE), phosphorus phosphatidylinositols (PI) and neutral wet goods.Phospholipid prod all has important Function and operation in body-care, diet nutritional and disease prevention and cure etc.In addition, phosphatide, due to its good emulsibility, wetability and surface-active, can be used as surfactant, emulsifying agent and lubricant etc. and is widely used in and cures, in candy, the food industry of vegetable milk wet goods.
China's scale reaches 279250 ton per days with the factory's soybean squeezing aggregated capacity that oils, and oil foot production scale is big well imagines.But, the scouring processes that China's fats and oils processing is produced generally only is focused on degumming effect and ignores the quality of oil foot, cause the problems such as the soybean lecithin ubiquity n-hexane insolubles content of domestic production is high, color and luster dark, transparency difference, the concentrated soybean phospholipid produced is caused mostly to be added in feed as nutrition fortifier, or abroad, range of application is very limited for low-price export.Therefore, if the soybean lecithin resource of China's abundant can be made full use of, Development and Production goes out the concentrated soybean phospholipid that n-hexane insolubles content is low, the transparency is good, color and luster is more shallow, not only can improve the added value of concentrated soybean phospholipid, and for follow-up phospholipid prod seriation, become more meticulous, customizations establishes application foundation.
At present, the existing method using inorganic membrane filtration to prepare food-grade concentrated phosphatide, but easily cause film blocking, flux depression in filter process, the cleaning difficulty of film, and equipment investment is costly; In addition, the method for existing employing centrifugal segregation n-hexane insoluble matter, too high to the requirement of centrifugal rotational speed (6000 ~ 20000rpm), be difficult to reach, energy consumption is high.
Summary of the invention
