Comparative example 2:
this comparative example is based on example 3, differing from example 3 in that: and (3) adding mature vinegar grains in the sauce mash fermentation process for mixed fermentation.
Comparing the flavor soy sauce prepared by the processes of examples 1 to 3 with the soy sauce of comparative examples 1 to 2, the parameters of starter-forming bacteria number, organic acid content, amino acid nitrogen content, mouthfeel and the like are shown in table 1:
TABLE 1
As can be seen from Table 1:
1. the flavored sauces of examples 1-3 had the following characteristics:
① the number of mixed bacteria of the finished koji is one order of magnitude, wherein the higher the addition amount of the mature vinegar culture in the koji making process, the better the bacteriostatic effect.
② the soy sauce with vinegar flavor of examples 1-3 has vinegar flavor but no loss of taste because acetic acid is the main acid substance in soy sauce and accounts for more than 50% of total acid, and the amino acid nitrogen content of soy sauce is different mainly because of the material proportion, and the contents of examples 1-3 are all at a more ideal level, which ensures the delicate flavor of soy sauce.
2. Comparison of the data of example 3 with comparative examples 1 and 2 shows that:
① comparative example 1 when no vinegar residue was added during koji making, the number of mixed bacteria in the soy sauce koji making was increased by one order of magnitude as compared with example 3, which indicates that the number of mixed bacteria became larger.
② comparison example 2 does not use mature vinegar, the lactic acid in the organic acid of the finished soy sauce accounts for 65.48% and is the main acid-forming substance, the mixed fermentation of the mature vinegar in the fermentation of the comparison example 3 uses the acetic acid to account for 53.63% and is the main acid-forming substance, which makes the soy sauce have different taste, the finished soy sauce of the comparison example 3 has a certain acetic acid taste, but the comparison example 2 does not have the same taste, and the comparison example 2 has a small difference of the amino acid nitrogen content compared with the comparison example 3, thus the addition of the mature vinegar in the fermentation process has no influence on the delicate flavor of the soy sauce.
The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are merely exemplary embodiments of the present invention, and are not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
