The mold auxiliary leavening agent consists of monascus purpureus, monascus fumosoroseus, geotrichum candidum and penicillium camembertii, wherein the ratio of the monascus purpureus to the penicillium is 5:2, the ratio of the monascus purpureus to the monascus fumosoroseus is 1:1, and the whole inoculation amount of the leavening agent is 1 x 108cfu/ml, and activating strains before inoculation, wherein the specific activation method comprises the following steps: the pure culture is carried out after the inoculation of the mould by using a culture medium of a Chaudhur culture medium.
And (4) obtaining a finished product after ripening, wherein the finished product is solid and rich in viscoelasticity, the finished product is a soft cheese product with a reddish inner coating and a white outer coating, and the packaging bag is partially vacuumized to 0.3bar and then is stored at the temperature of-4 ℃.
Comparative example 1
The preparation method is as described in example 1, except that the calcium chloride content in example 1 is increased to 300mg/kg, and the partial vacuum degree of the packaging bag is changed to-0.6 bar.
And (3) finished product: soft cheese products with a reddish inner coating of white casing.
Comparative example 2
The preparation method is as in example 2, except that the ripening condition is changed to 35 ℃ for 5 days, and the packaging is carried out by non-vacuum packaging.
And (3) finished product: soft cheese products with a reddish inner coating of white casing.
Comparative example 3
Commercial camembert cheese.
The basic physicochemical properties of each example and comparative example are shown in table 1, and the measurement methods refer to the relevant methods among AOAC92608, AOAC2001, AOAC933_05, AOAC935_42, and AOAC 99143:
TABLE 1
Example 1 Example 2 Example 3 Example 4 Comparative example 3
Moisture content 50.00% 51.18% 47.16% 49.16% 51.47%
Protein g/100g 19.3 18.7 19.9 19.5 18.0
Fat g/100g 17.9 17.5 18.2 18.0 21.0
Ash content g/100g 6.4 7.2 7.8 7.5 5.5
Total dietary fiber g/100g 6.2 5.2 6.8 5.8 3.8
As can be seen from Table 1, the monascus white mold cheese has a relatively low moisture content and a relatively low fat content, and researchers have studied monascus to find that the monascus white mold cheese has a certain fat degradation effect, which is irrelevant to the reduction of the fat content. In addition, the dietary fiber of the monascus white mold cheese is obviously increased.
The texture parameters of the examples and comparative examples are shown in table 2, and the measurement methods refer to the relevant contents in "the influence of different leavening agents on the aroma components and texture properties of Edam cheese" (J ].2017, 04):
TABLE 2
Example 1 Example 2 Example 3 Example 4 Comparative example 1 Comparative example 3
Hardness per gram 1376.83 1296.84 1484.26 1387.59 1862.54 1341.35
Elasticity 91.87 90.68 90.57 93.56 70.53 82.14
Viscosity of 747.69 805.91 729.48 857.64 498.28 559.84
As can be seen from Table 2, the viscoelasticity of the Monascus white cheese is significantly improved over that of the white cheese, while the hardness is too high and the viscoelasticity is also poor for comparative example 1, indicating that too much calcium chloride and improper packaging can affect the ripening of the cheese.
The results of analysis of nutrient components of each example and comparative example are shown in Table 3, and the measurement methods are described with reference to the relevant contents in P.Pattanagaul, R.Pinthong, A.Phyanmongkhol and S.Tharatha, "Melinolin, citin and documents of additive and kak transferred by Monascus sp," International Journal of Food Microbiology, vol.126, No.1, pp.20-23,2008:
TABLE 3
Example 1 Example 2 Example 3 Example 4 Comparative example 3
Lovastatin (mug/g) 3.4 1.8 5.2 2.9 0
Gamma-aminobutyric acid (mu g/g) 1.2 1.6 2.5 1.7 2.3
As can be seen from Table 3, the Monascus white cheese was able to produce lovastatin, which had a hypolipidemic effect, but was not detected in the white cheese. The gamma-aminobutyric acid content is equivalent to the amount of the white mould cheese.
The microbiological indicators of the examples and comparative examples are shown in table 4, and the measurement methods refer to the relevant contents in the national standard GB 4789.3:
TABLE 4
Figure BDA0002861644110000091
Figure BDA0002861644110000101
As can be seen from Table 4, the ripening temperature as well as the form of the packaging have a significant influence on the quality of the final product.
Samples prepared in each example and comparative example were tasted by 20 sensory evaluators (10 for men and women, and 10 for dairy industry researchers in China), and sensory evaluation was performed on the aspects of tissue morphology, appearance, flavor, mouthfeel, etc., cheese sensory evaluation criteria are shown in table 5, and cheese sensory evaluation results are shown in table 6:
