Coherent detection of the invention:
One, the correlation of soy sauce and soya sauce
Detection method according to national standard GB18186-2000 make soy sauce in physical and chemical index regulation carry out.
The main physical and chemical index of 1 high salt liquid soy mash, in the prior art beans sauce compares
Stronger with product homology due to producing, emphasis compares the main physical and chemical index of high salt liquid soy mash and beans sauce
Compared with, so show beans sauce to high-salt dilute soy slag can inclusiveness.
The dynamic analysis of 1.1 total acids
Total acid content variation during fermentation of high-salinity dilute soy as shown in Figure 1, slow ascendant trend is presented in total acid content,
Weighing apparatus is flattened out 50 or so.
Fig. 2 shows that the fermentation of beans sauce tends to be steady in the variation of 33 days or so total acids.This and high-salt diluted state fermentation soy
In, the variation of total acid is almost the same.
The dynamic analysis of 1.2 amino-acid nitrogens
As a result as shown in figure 3, amino nitrogen 30 days during high-salt fermentation improved comparatively fast in the past until 105 days are in
Slow growth trend, but entire change is more steady.
Fig. 4 shows that the fermentation of beans sauce tends to be steady in the variation of 10 days or so amino-acid nitrogens.This and high-salt dilute soy
In, the variation tendency of amino nitrogen is more consistent, but content is low compared with sauce fermentation wine with dregs, at the end of amino-acid nitrogen content be 7g/
100g. or so, this should be related with water content.
When fermentation ends being shown in Fig. 5, the result of oil is taken to can be seen that hair oil, two oil, the amino-acid state in three oil
Nitrogen content successively reduces.Find out simultaneously, the content of the amino nitrogen of two slags is about 0.7g/100g, can still meet the requirement of beans sauce.
When taking moisture content roughly the same with beans sauce, the later stage fermentation of beans sauce can be added, be used to produce after may also pass through colloid mill
Sauce, i.e. flavouring-soy-sauce or function sauce etc. are deployed, three oil operations are saved.
The dynamic analysis of 1.3 salt-less solids
Salt-less solid changes of contents during fermentation of high-salinity dilute soy as shown in fig. 6, change total during the fermentation
Body is more gentle.At the end of the content of salt-less solid be 15g/100g or so.
It can also be seen that the variation of solid content and the result of Fig. 6 have same effect from Fig. 7.
2 raw material applied analyses
The raw materials for production of beans sauce are soya bean and flour, and the raw materials for production of high-salt dilute soy are soybean and wheat.The two exists
Too big difference is had no on raw material.Therefore it is analyzed in the level of raw material application remaining using ingredient in residue of soya.
When Fig. 8 can be seen that high-salt fermentation about 30 days, raw material decomposes are substantially completed, the sauce after washing process
Crude protein content measured by slag is about 13g/100g, and Crude starch content is about 7g/100g.
As shown in figure 9, containing crude protein without the residue of soya after washing process is about 18g/100g, Crude starch is about 11g/
100g.More washed crude protein content does not improve 5g/100g.And the residue of soya is installed in its sauce squeezed in cloth bag and contains
Amount should be about 44g/100g, and therefore, the protein content improved in residue of soya is solvable low molecular protein and amino nitrogen, directly may be used
It takes in sauce.
Above data more fully hereinafter demonstrates the feasibility that residue of soya is applied to beans sauce production, once implement in the industry,
Soy sauce residues being applied in time completely.It is closed in soy sauce production according to GB-T 24399-2009 soya sauce national standard
In the requirement of soya sauce physical and chemical index, the total acid of soy sauce residues and the content of amino nitrogen are controlled, accomplishes soy sauce, beans sauce production one
Body really realizes that soy sauce produces zero-emission, effectively promotes the overall technology and management level of industry.
Two, through detecting, soya sauce of the present invention meets national standard.
1. brewing materials protein content is analyzed
Soybean original legumin content is 38-40g/100g, and it is about 18g/100g that the residue of soya without washing, which contains crude protein, is pressed
It is 2:1-3:1 reckoning according to the mass ratio of soya bean and high-salt dilute soy slag, the crude protein content in mixed raw material are as follows: 31-
35g/100g can satisfy the requirement of crude protein needed for beans sauce is made.
2. brewing materials content of starch is analyzed
Soybean original beans content of starch is about 10g/100g, and it is about 11g/100g that the residue of soya without washing, which contains Crude starch, is pressed
It is 2:1-3:1 reckoning according to the mass ratio of soya bean and high-salt dilute soy slag, the Crude starch content in mixed raw material is about are as follows: 10g/
100g can satisfy the requirement of Crude starch needed for beans sauce is made.
3. the undecomposed raw material branches and leaves of soy sauce residues help to generate beans sauce characteristic flavor ingredient
4- vinyl guaiacol (4-EG) can assign the characteristic sootiness perfume (or spice) of beans sauce and paste flavor gas, while also have
With the effect of saline taste, it is considered to be the characteristic flavor substance in sauce.The threshold value of 4-EG is very low, and there are about 0.5mg/kg can reach
The level identified can promote fragrance and flavor containing 1-2mg/kg in sauce.The precursor substance of 4-EG is present in cereal
Cell wall in, the arabinose that the monomer and dimer of ferulic acid are mainly connected to araboxylan in the form of ester bond is residual
On base.In brewing process, cell wall degrading enzyme (such as zytase) the function cells wall construction of microorganism secretion is simultaneously dropped
Solution forms the substance of small-molecular-weight, destroys the ester bond that ferulic acid is connected with polysaccharide followed by feruloyl esterase (FAE), will tie
Close the ferulic acid separate out on lignin glycocide.Then under ferulic acid decarboxylase (FDC) effect, asafoetide acid decarboxylation is raw
At 4- vinyl guaiacol (4-VG), then via 4- vinyl guaiacol reductase under the action of, 4- vinyl guaiaci lignum
Phenol is reduced into 4-ethyl guaiacol (Figure 10).
Containing the raw material branches and leaves not being decomposed in soy sauce residues, help to generate characteristic flavor ingredient 4- in brewing process
EG.Assign beans sauce dense paste flavor gas.
