Description
Technical field
A kind of production method of food-level concentrated soybean phospholipid belongs to the soybean lecithin technical field.
Background technology
Food-grade phosphatide derives from plants such as soybean; be to get a foothold by the colloid that the workshop section of coming unstuck in the soybean oil process produces to obtain through processing; the complex mixture that it is made up of the acetone insoluble matter of phosphatide; it mainly is phosphatid ylcholine (PC), phosphatidyl-ethanolamine (PE) and phosphatidylinositols (PI) that its phosphatide is formed; soybean lecithin except have softening blood vessel, liver-protective functional, also have emulsibility, wetability, colloidality etc. and use character.In countries such as America and Europes, soybean lecithin has become very universal nutraceutical, and in the health products hit parade of sale of the U.S., soy phospholipids occupies front three.In addition, because its special use character, the soybean lecithin product becomes one of maximum additive of use in dairy products processing, margarine, confectionary fat, baked product, cosmetics, field of petrochemical industry.
For food level soybean phosphatide, comprise high-quality phospholipid prods such as food-level concentrated soybean phospholipid, powder phospholipid, modified phospholipid, these product demands of China mainly rely on import to satisfy.Domestic phosphatide is present with the main difference table of high-quality phosphatide in the world: (1) impurity content height (the insoluble object height of ether), and (2) color and luster is dark, and (3) kind is few.From the product quality angle, domestic production phosphatide is mainly due to color and luster, the transparency, the insoluble object height of ether and can't reach the food-grade requirement.In order to reach the requirement of food level soybean phosphatide, the explained hereafter food level soybean phosphatide of the crude oil secondary filter that domestic employing is external.Since the existence of macromolecular substances such as the outstanding glycolipid of mixing and following existence in the soybean lecithin, lipoprotein, and make the soybean lecithin product of production on the transparency, still have very big problem.The present invention utilizes the inoranic membrane isolation technics to solve at this problem.
Membrane separation technique is new and effective, the accurate isolation technics of succeeding in developing in 20th century, and it is that material science combined with intersecting of medium isolation technics, with the separative efficiency height, equipment is simple, easy to operate and advantage such as energy-conservation, is applied to every field.Difference according to membrane material can be divided into organic film and inoranic membrane two big classes.Organic film material has: cellulose family, polyamide-based, aromatic heterocycle class, polysulfones, silicone rubber kinds, fluoro containing polymers class etc.But organic film has its fatal weakness, and as non-refractory, acid and alkali-resistance not, mechanical strength is not enough, and organic solvent-resistant is not easy to stop up, not easy to clean.These shortcomings make it be difficult to be applied to oil prodution industry.Inoranic membrane involved in the present invention is meant inorganic ceramic membrane or stainless steel membrane, inoranic membrane can be divided into perforated membrane and dense film two big classes with regard to its surface texture, dense film has very high selectivity, mostly be metal film, the permeability of perforated membrane wants high than dense film, but selectivity is lower, and they respectively have characteristics, complement each other, each is fit to different occasions.The difference that film separates according to membrane aperture can be divided into counter-infiltration (filter of (1nm), sodium (about 1nm), ultrafiltration (1-100nm) and micro-filtration (0.1um-10um).The molecular cut off of ultrafiltration is 103-106, and micro-filtration is used for the clarification of solution.Ultrafiltration and micro-filtration are applied to the preparation of recovery, dairy industry, the juice clarification of oily waste water, sero-abluminous extraction, high purity water more.
Summary of the invention
The production method that the purpose of this invention is to provide a kind of food-level concentrated soybean phospholipid realizes that food-grade phosphatide no longer is subjected to the restriction of grease processing technique, realizes the purpose of industrialization, scale.Core of the present invention is the decolorization and the inorganic membrane filtration process of feed grade concentrated soybean phospholipid dissolution system, on this basis, solved the problem that exists during the original food-level concentrated soybean phospholipid of China is produced fully, help its popularization, and help to change the situation of this product dependence on import of China in food, medicine, cosmetics market segment.
Technical scheme of the present invention: adopting the feed grade concentrated soybean phospholipid is raw material, dissolve with non-polar solvens such as n-hexanes, adopt the food-grade hydrogen peroxide that this dissolution system is decoloured, mixed liquor after adopting inoranic membrane (comprising inorganic ceramic membrane or stainless steel membrane) to decolouring filters, adopt dual evaporation to remove wherein solvent etc. again and follow material, three parts are integrated the production method that constitutes food-level concentrated soybean phospholipid.
Mix and decoloration process: feed grade concentrated soybean phospholipid raw material mixed according to mass ratio with n-hexane or other non-polar solven in 1: 2～1: 6, the dissolving back adds the food-grade hydrogen peroxide of feed grade concentrated soybean phospholipid quality 1%～4%, stir decolouring 20min～60min down at 20 ℃～60 ℃, decolouring finishes to enter filter process.
Inorganic membrane filtration technology: the mixed liquor after selecting for use inorganic ceramic membrane or stainless steel membrane to decolouring filters, selecting membrane aperture for use is 50nm-500nm, mixed liquor after the decolouring is placed the filtration head tank, carrying out inorganic membrane filtration under the following conditions handles: 20 ℃-50 ℃ of filtration temperatures, inlet pressure 0.05MPa-0.3MPa, outlet pressure 0-0.2MPa, filtered solution is entered the double evaporation-cooling process, filtered residue removes solvent and moisture wherein under 70 ℃-90 ℃, and squeezes into the residue that obtains in the dregs of rice or be mixed in the feed grade concentrated soybean phospholipid.
Dual evaporation precipitation technology: through containing 60%～80% solvent in the filtered solution behind the membrane filtration, enter the dual evaporation system, through after the one-level evaporation solvent in the system being reduced to 10%～20%, evaporation conditions is: 50 ℃～70 ℃ of temperature, residual voltage makes solvent less than 50mg/kg less than 2kPa behind the double evaporation-cooling, evaporation conditions is 60 ℃～90 ℃, residual voltage is less than 2KPa, and the food-level concentrated soybean phospholipid that obtains reaches state-set standard.
