Abstract
A closed-loop low-salt solid fermentation process for soy features that the traditional processes of biodegradating protein for raw materials and acid hydrolysis of protein for dregs are combined, so that the residual less salt, residual protein and a certain quantity of intermediate are reused in production. Obtained soy has the advantages of high yeild, rich amino acids, and better chromaticity and taste.
Description
The invention belongs to the preparation of food or foodstuff, i.e. flavoring soy sauce preparation technology.
Soy sauce is as China's traditional condiment, and the technology that present domestic most factories adopt is the exclusive low salt solid state fermentation of China.This technology is bacterial classification with aspergillus oryzae shanghai brewing 3042, and defatted soybean, wheat bran are raw material, under solid state fermentation conditions, adds 15% salt solution and makes the sauce unstrained spirits.After the fermentation of sauce unstrained spirits, after three pouring systems, obtain soy sauce crude oil.Crude oil obtains finished product after the allotment sterilization, residue of soya is as waste discharge.In fact, in residue of soya, contain many compositions that are not decomposed.Contain the bulk fermentation intermediate product simultaneously.And at present, the soy sauce industry is directly discharged residue of soya as discarded object owing to there is not rational treatment process, has not only wasted resource but also cause environmental pollution.
Purpose of the present invention is exactly on the basis of existing technology, make full use of and contain a small amount of salt, residual protein and a certain amount of fermentation intermediate product in the residue of soya, residue of soya is carried out chemistry and biological dual processing, making residue of soya return to be used for producing as secondary raw material goes, turn waste into wealth, to reduce the waste and the environmental pollution of resource, improved original zymotechnique greatly, improved raw material availability and yield rate.
The technology of the present invention solution is: the existing raw material biodegradation of soy sauce protein technology is combined with residue of soya acid protein hydrolysats matter technology, the residue of soya that produces behind the sauce fermentation through resulting protein hydrolyzate after the acid hydrolysis again after carrying out a biological disposal upon secondary enter in the sweat the carrying out that participates in fermentation, and then form optimum close circulation technology.
Technological process of the present invention is as follows: accompanying drawing is soy sauce low-salt solid close circulation technology flow chart one, soy sauce preparation technology:
With defatted soybean, wheat bran is raw material, and with 6: 4 or ratio mixing in 5: 5, general ratio was 6: 4.According to this ratio, can calculate the basis (seeing Table 1) of soy sauce mixed material by the normal composition of dregs of beans and wheat bran.
Table 1 raw materials of soy sauce fundamental component
Unit | Dregs of beans | Wheat bran | 6: 4 mixed materials | |
Moisture content | ????% | ????10 | ????12 | ????10.8 |

Dregs of beans is mixed → material moistening → steaming material → cooling → inoculation (aspergillus oryzae 3042 → triangular flask → koji tray expansion) → koji → Cheng Qu → pulverizing → system unstrained spirits → heat-preservation fermentation → ripe sauce unstrained spirits → head with wheat bran and drench oil, two pouring oil, three pouring oil (residue of soya).
Above technology is prior art, its technological parameter, condition, and inoculum concentration is known.Two, residue of soya is handled:
All kinds of nutrition compositions are complete in the residue of soya, and protein content is higher, and existing fermentation intermediate product has excessive albuminate again in the protein component.(the residue of soya composition sees Table 2)
Table 2 residue of soya composition
1. residue of soya is entered in the hydrolytic reaction pot, with concentration be 36% hydrochloric acid allocate to the reactant liquor concentration of hydrochloric acid be 10%, feed Steam Heating, treat that cold air arrange closed reactor afterwards.2. work as reacting kettle inner pressure and rise to 1.2kg/cm
2Back pressurize, reaction temperature are 110-125 ℃, and the reaction time is 24 hours.Question response finishes to stop heating, feeds cooling water, reduces to room temperature.3. hydrolyzate is filtered with being pumped in the diaphragm pressing machine, filtrate is sent into neutralization bucket, uses NaCO
3Or NaOH is neutralized to PH4.8-5.4, and water content is in the use that acts as a fuel of 45% filter cake, and filtrate enters next step biological treatment.4. be that bacterial classification leaves standstill cultivation 7-15 days with the above-mentioned amino acid hydrolyticsolution of producing from the acid hydrolysis mode under 30 ℃ with the soy sauce aroma-producing yeasts, carry out a biological disposal upon.5. hydrolyzate adds finished product Daqu heat-preservation fermentation, and fermentation condition is with existing technology.Be fermentation time 25 days, early stage, the product temperature was 48-50 ℃, 41-45 ℃ of later stage product temperature.6. ripe sauce unstrained spirits drenches oily method with existing technology.7. residue of soya returns in the production as secondary raw material through the present invention's processing and goes, and forms a benign cycle zymotechnique.8. filter the humus that obtains after the residue of soya hydrolysis and can be used as fuel.Residue of soya hydrolyzate amino acid composition sees Table 3.
