Abstract
The invention discloses a process for extracting soybean protein isolates at a high extraction rate. A balance tank which is designed to be connected in series with an extraction tank is additionally arranged in an extraction process, and an emulsification pump is arranged between the extraction tank and the balance tank. The process comprises the steps of extracting materials in the extraction tank, then grinding and crushing the materials through the emulsification pump, then further extracting the materials in the balance tank, and next, separating the materials in a separator. According to the invention, a semi-continuous design is adopted in the extraction process, and the liquid level in the balance tank is always kept stable, so that the process not only is improved in stability, but also can be used for increasing the extraction rate of the soybean protein isolates, reducing the production cost and increasing the enterprise revenue.
Description
Technical field
The present invention relates to a kind of extraction process of soybean protein isolate, be specifically related to a kind of soybean protein isolate extraction process of high extraction, belong to soybean further process field.
Background technology
Soybean protein isolate is as a kind of full price protein foodstuff additive take dregs of beans as raw material production, be rich in the multiple essential amino acids such as Methionin, tryptophane, α-amino-isovaleric acid, there is the features such as good water-retentivity, tackiness, gel-type and emulsifying property, be widely used in the food such as meat product, milk-product, candy, cake.
At present, the production technique of soybean protein isolate is mainly " it is heavy that alkali is proposed acid " method, in the Parallel Design that extracts 2 of the common employings of workshop section or multiple extractors, the technique of the material lixiviate that hockets, maintain certain extraction time by alternately feeding intake, guarantee the effect of protein extraction.Conventional soybean protein isolate extracts workshop section's flow process as shown in Figure 1:
Extractor 1, extractor 2, extractor 3 Parallel Designs.Material after lixiviate completes in extractor, is opened the pneumavalve switch on transport pipe, the mass transport in extractor 1 to separating machine 5 is separated with separating machine 6 with impeller pump 4; After feed separation in extractor 1 completes, according to above-mentioned flow process, the material in separation and Extraction tank 2, after the feed separation in extractor 2 completes, according to above-mentioned flow process, the material in separation and Extraction tank 3, and so forth, until whole extraction workshop section completes.
The main drawback of said extracted technique is: protein extracting ratio is low and technology stability is poor, wherein technology stability is poor is mainly manifested in the unstable of separating machine flow, along with the reduction of material liquid level in extractor, cause the reduction of material potential energy, thereby cause the flow of supplying with separating machine to diminish gradually, material in each extractor all presents this variation tendency of going round and beginning again, finally cause the separating effect of separating machine inconsistent, make solid content and the purity of protein of extracting solution be difficult to stablize, not only affect the effect of settling of Suan Chen workshop section, and quality and the stability of product are reduced.
Summary of the invention
The object of the invention is to overcome the shortcomings and deficiencies of existing extraction process, a kind of superior product quality, process stabilizing, soybean protein isolate extraction process that protein extracting ratio is high are provided.
For achieving the above object, the present invention is by the following technical solutions:
A soybean protein isolate extraction process for high extraction, is provided with and the surge tank of extractor series design in protein extraction workshop section;
Further: extractor material out carries out further lixiviate through pump delivery to surge tank;
Further: the continuous input and output of material in described surge tank, it is stable that liquid level keeps;
Preferably: described technique, also contain emulsification pump, described emulsification pump is between extractor and surge tank.
Beneficial effect of the present invention is, the extraction yield of the soybean protein isolate of common process protein extraction workshop section is about 88% left and right, production yield 42%-44%, main technologic parameters: the index of stability of soya-bean milk PH, soya-bean milk BX, the heavy PH of acid is less than 80%.And adopt soybean protein isolate extraction process of the present invention, protein extracting ratio effectively to improve 3%～10%, and reaching more than 94%, yield promotes 1%～5%, reaches more than 45%, and protein extraction workshop section processing parameter index of stability promotes 10%～30%, reaches more than 95%.
Accompanying drawing explanation
Fig. 1 shows conventional soybean protein isolate extraction process flow process;
Fig. 2 shows extraction process flow process of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
Embodiment 1
As shown in Figure 2: the extractor 1, extractor 2 Parallel Designs that are used alternatingly as charging tank, change to each other by operated pneumatic valve.Surge tank 3 and described extractor 1, extractor 2 series design.By process water and raw material dregs of beans by weight 11:1 at extractor 1 or extractor 2 is interior mixes, and material liquid pH value is adjusted to 8.0 with NaOH solution, under temperature 50 C, carry out soybean protein isolate lixiviate, extraction time is 15 minutes, in leaching process, constantly stir with the speed of 70 revs/min, to guarantee the extraction effect of soybean protein isolate.After lixiviate completes, open the pneumavalve switch on transport pipe, the mass transport in extractor 1 or extractor 2 is carried out to further lixiviate to surge tank 3, extraction time 20 minutes with pump.After lixiviate completes, through impeller pump 5, the mass transport in surge tank 3 to separating machine 6 is separated with separating machine 7.Due to the continuous input and output of the material in surge tank 3, liquid level in surge tank 3 remains at 50% left and right, solve liquid level unstable on separating the impact of flow, thereby the stability of extraction process and the extraction yield of soybean protein isolate are improved, adopt this technique, the extraction yield of soybean protein isolate is 95.8%.
Further, for improving the extraction effect of soybean protein isolate, between extractor 1, extractor 2 and surge tank 3, emulsification pump 4 is installed, material is from extractor 1 or extractor 2 extractions, after emulsification pump 4 grinds, enter again surge tank 3 and carry out further lixiviate, after lixiviate completes, through impeller pump 5, the mass transport in surge tank 3 to separating machine 6 is separated with separating machine 7.Material particular diameter after emulsification pump 4 grinds is controlled at 60 order left and right, and the extraction effect of soybean protein isolate is obviously increased.
