Abstract
The invention relates to a method for improving solubility of concentrated protein powder by means of the fatty acid combination or by removing calcium in casein micelle. Fatty acid is added into a raw material dairy product to reduce a pH value of protein, calcium in the casein micelle is combined or removed, and spray drying is carried out to obtain the concentrated protein powder rich in functional fatty acid; fatty acid calcium and a protein solution can also be separated by means of simple centrifugal operation, and the protein solution is dried in a spray mode to obtain the concentrated protein powder partially decalcified. The method has the advantages that the production process is simple and free of pollution; functional milk powder is rich in beneficial fatty acid, after being partially decalcified, the protein solubility is good, and storage stability is high; the concentrated milk protein powder is decalcified partially (10-30%), and nutritional value and functionality of milk protein are retained, and solubility is improved; the two products can be used for producing high-protein food such as liquid milk beverages, yoghourt, cheese and nutrition bars; fatty acid calcium obtained by means of centrifugal separation can be applied to feed processing.
Description
Technical field
The present invention relates to a kind of by aliphatic acid in conjunction with or remove the intrafascicular calcium of casein glue and improve concentrated milk protein powder and dissolve steadyMethod qualitatively, belongs to milk powder manufacture field.
Background technology
Lactoprotein is because having good nutrition and functional characteristic, and in food processing industry, is widely used as a kind of important albumenBatching. Along with the development of foods processing technique, the kind of lactoprotein goods constantly increases, and wherein concentrated milk protein is that a class is relativeNovel albumen batching is that skim milk is dried by evaporation and concentration and spraying the high egg of a class obtaining again after ultrafiltration and filter washWhite powder. The butt protein content of concentrated milk protein is between 50-85%, and its albumen composition is almost identical with breast,Be particularly useful for the production of cheese. In addition, concentrated milk protein also can replace skimmed milk, casein or WPC etc. and quiltBe applied in nutraceutical.
The solubility exponent (SolubilityIndex, SI) of concentrated milk protein is very low, and rehydration is poor, and this also makes concentrated newborn eggWhite extensive use is subject to certain limitation. At present, a large amount of work sutdies concentrated milk protein reconstitution process change, storage barPart is on aspects such as the deliquescent impact of concentrated milk protein and the insoluble mechanism of concentrated milk protein. Research shows due to concentrated milk proteinProtein content higher, in storage, dissolubility reduces comparatively fast, therefore its storage-stable is poor compared with property. Lower dissolving in additionProperty has also had influence on other functional character of concentrated milk protein, and for example as protein-enrichmen, agent is applied to albumin milk to concentrated milk proteinWhen the production of goods, be subject to its impact of redissolving degree can form caking, affect the quality of product. Therefore concentrated milk protein is in room temperatureDown can be fast, dissolve completely. be its basis in Applications in Food Industry. Deep research is also pointed out, controls caseinThe stability of micella is very important for dissolubility and the storage stability of concentrated milk protein, in conjunction with or remove the free calcium in Ruzhong,Reduce αsThe quick property of calcium of-casein and beta-casein and form hydrated sheath stop between protein body mutually near etc. means, forProtection casein micelles, improves the steady dissolution of concentrated milk protein very important, and the method for having reported comprises and adds calcium ionChelating salt, hydrophilic colloid and utilize ion exchange column decalcification etc.
Summary of the invention
Lower and the poor problem of rehydration for MPC solubility exponent, the invention provides one and utilizes aliphatic acid combination or removeCalcium improves the deliquescent method of concentrated milk protein. The method by aliphatic acid and calcium ion with and and concentrated milk protein betweenInteract, in conjunction with or remove free calcium and the intrafascicular calcium of casein glue in concentrated milk protein solution, improve concentrate newborn eggWhite dissolubility, retains the nutritive value of its high protein, expands the application of concentrated milk protein in food industry. This patent techniqueEasy, efficiency is very high, is applicable to very much suitability for industrialized production.
For achieving the above object, the technical scheme that the present invention takes is: taking protein solution as basis, the solid content of regulator solution containsAmount and pH value are hatched solution and aliphatic acid afterwards under constant temperature, and fatty acid mixed and solution by a certain percentage regulatesThe total solids content of final solution changes solution into superhigh-voltage homogenizing machine homogeneous after pre-homogeneous under high speed dispersor, directly entersRow spraying is dried or is dried and prepares albumen powder by spraying after simple centrifugation fatty acid calcium again. Concrete technologyAs follows:

3, regulate pH: the extremely pH of the suitable dissolving of corresponding albumen of pH that uses the sodium hydroxide solution regulator solution of 1moL/L.
4, constant-temperature incubation: solution, aliphatic acid and ultra-pure water are placed in isoperibol and are hatched the regular hour respectively.
5, mix: in solution, add aliphatic acid, supplementary ultra-pure water reaches the dry gross mass with solution of spraying, stir,Utilize the saponification of aliphatic acid and calcium, and interaction between aliphatic acid and albumen, deproteination solution and casein glueIntrafascicular calcium.
6, homogeneous: by solution pre-homogeneous 1min～5min, afterwards continuous homogenizing 3～5 in superhigh-voltage homogenizing machine under high speed dispersorInferior, pressure is 28Mpa～40Mpa.
7, two be separated (selective step): separate the fatty acid calcium layer after saponification and remove difference by simple centrifugally operatedThe emulsion layer of degree calcium.
8, spraying is dry: spray-dired inlet temperature is at 100 DEG C～130 DEG C, and the temperature difference of inlet temperature and outlet temperature is30 DEG C～50 DEG C, outlet temperature is according to pump speed and spray gas Flow-rate adjustment.
9, such albumen powder is joined to the correlated performance that can improve product in product.
