Through detection, the fermented soya beans meet the standard.
The correlation test of the present invention is as follows:
correlation between soy sauce and fermented soya beans
1.1 comparison of the main physicochemical indexes of Soy sauce and fermented soya beans
As the homology between the production and the product is stronger, the main physicochemical indexes are compared, thereby showing the compatibility of the fermented soya beans to the soy sauce residue. The detection method is carried out according to the physicochemical indexes of the brewed soy sauce in the national standard GB18186-2000 and the fermented soya beans in the group standard T/GZSX 014-2018.
1.1.1 dynamic analysis of Total acids
The total acid content changes in the high-salt dilute soy sauce fermentation process as shown in fig. 1, and the total acid content is in a slow rising trend and tends to be balanced in about 50 days.
The total acid content change during fermentation of fermented soybeans is shown in fig. 2, and the change of the total acid tends to be smooth in about 20 days, which is basically consistent with the change of the total acid during the brewing process of soy sauce.
1.1.2 kinetic analysis of amino acid Nitrogen
As shown in fig. 3, the amino nitrogen in the high-salt dilute fermentation process increased faster before 30 days until 105 days, but the overall change was more stable.
As shown in FIG. 4, the fermented soybean is fermented for about 10 days, and the change of amino acid nitrogen tends to be smooth. This is consistent with the trend of amino nitrogen during soy sauce fermentation, but the content of amino nitrogen is slightly lower than that of soy sauce, and the content of amino nitrogen at the end is about 0.66g/100g, which is related to the water content.
As shown in FIG. 5, the contents of amino acid nitrogen in the first, second and third oils were sequentially decreased as the result of oil extraction at the end of fermentation. According to the local standard DB 61/T428 and the community standard T/GZSX 014 and 2018 of the fermented soya beans, the amino acid nitrogen of the fermented soya beans is required to be more than or equal to 0.40g/100 g. The content of amino nitrogen in the three residues is about 0.5g/100g, and the three residues can still meet the requirements of fermented soya beans.
1.1.3 dynamic analysis of salt-free solids
The change of the salt-free solid content in the high-salt dilute soy sauce fermentation process is shown in fig. 6, and the total change in the fermentation process is relatively gentle. The content of the salt-free solid at the end was about 15g/100 g.
As can also be seen from fig. 7, the change in solid content is in the same tendency as the result of fig. 6.
2.2 raw material application analysis
The raw materials for producing the fermented soya beans comprise soybeans, bran and the like, and the raw materials for producing the soy sauce comprise soybeans, wheat, bran and the like. The two are not too different in raw material. Therefore, at the level of raw material application, the available components remaining in the soy sauce residue are analyzed.
As shown in FIG. 8, the fermented soybean was fermented for about 10 days, and the change of protein was smooth, indicating that the decomposition of the raw material was almost completed, and the protein content of the fermented soybean was about 32g/100 g.
As can be seen from FIG. 9, the decomposition of the raw material was almost completed in about 30 days of the high-salt dilute state fermentation, and the crude protein content and the crude starch content of the water-washed sauce residue were about 13g/100g and 7g/100g, respectively.
As shown in FIG. 10, the sauce residue without washing with water contained about 18g/100g of crude protein and about 11g/100g of crude starch. The content of the crude protein is increased by 5g/100g compared with that of unwashed crude protein. The sauce content of the sauce residue obtained by packing the sauce residue in a cloth bag and squeezing should be about 44g/100g, so that the increased protein content in the sauce residue is soluble low molecular protein and amino nitrogen, and can be directly carried into sauce.
Second, through the detection, the fermented soya beans of the invention accord with the standard.
1. Analysis of protein content in brewing Material
The raw soybean protein content of the soybean is 38-40g/100g, the sauce residue which is not washed by water contains about 18g/100g of crude protein, and the crude protein content in the mixed raw materials is calculated according to the mixture ratio of 90-100g of soybean, 10-20g of bran and 20-40g of sauce residue: 30-33g/100g, which can meet the requirements of crude protein required by fermented soya bean brewing.
2. Analysis of starch content in brewing materials
The starch content of the soybean raw bean is about 10g/100g, the sauce residue which is not washed by water contains about 11g/100g of crude starch, and the crude starch content in the mixed raw materials is calculated according to the mixture ratio of 90-100g of soybean, 10-20g of bran and 20-40g of sauce residue: 10-11g/100g, can meet the requirements of the crude starch required by fermented soya bean brewing.
3. Branches and leaves of undecomposed raw materials of soy sauce residues are helpful for generating characteristic flavor components of soy sauce flavor
4-Vinylguaiacol (4-EG) imparts characteristic smoke and sauce aroma to soybean paste, and also has a function of neutralizing salty taste, and is considered as a characteristic flavor substance in the paste. The threshold value of 4-EG is very low, about 0.5mg/kg can reach the level of identification and recognition, and 1-2mg/kg can improve the aroma and the flavor in the sauce. The precursor substance of 4-EG is present in the cell wall of cereals, and the monomer and dimer of ferulic acid are mainly connected to the arabinose residue of arabinoxylan in the form of ester bond. During brewing, cell wall degrading enzymes (e.g., xylanase) secreted by microorganisms act on cell wall structures and degrade them to form small molecular weight substances, which in turn dissociate ferulic acid bound to the lignin glycoside by destroying the ester bonds connecting ferulic acid and polysaccharides via feruloyl esterase (FAE). Subsequently, ferulic acid is decarboxylated to produce 4-vinylguaiacol (4-VG) under the action of ferulic acid decarboxylase (FDC), and then 4-vinylguaiacol is reduced to 4-ethylguaiacol under the action of 4-vinylguaiacol reductase, as shown below:
Figure BDA0002379777090000061
the sauce residue contains undecomposed branches and leaves of raw materials, is mostly cellulose, and contributes to the generation of sauce flavor type characteristic flavor component 4-EG in the brewing process. Endows the fermented soya beans with thick sauce fragrance.
The above data more fully demonstrate the feasibility of applying soy sauce residue to fermented soybean production, once implemented in the industry, soy sauce residue can be applied in a complete and timely manner. In the production of the fermented soya beans, the content of total acid and amino nitrogen in the soy sauce residues is controlled according to the requirements of DB 61/T428-.
Although the embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that: various substitutions, changes and modifications are possible without departing from the spirit and scope of the invention and the appended claims, and therefore the scope of the invention is not limited to the embodiments disclosed.
