preparation example Construction
[0027] In a specific embodiment, a kind of preparation method of monascus cheese is provided, it comprises the following steps:
[0028] ①Direct inoculation, the sterilized raw milk is inoculated with lactic acid bacteria starter and Monascus mature agent at 35-39°C, and pre-acidified to a pH of 6.3-6.4; the sterilization method and conditions are pasteurization , the pasteurization temperature is 68-73°C, and the time is 15-25s; raw milk refers to the natural mammary gland secretion squeezed from the normal udder of a healthy cow; and raw milk refers to the raw milk after pretreatment.
[0029] Wherein, the Monascus maturation agent is Monascus purple spore liquid, and the preparation method of the Monascus purple spore liquid comprises the following steps: inoculating Monascus purple into the liquid culture medium of Monascus purple, and activating the content of Monascus purple in the culture medium to 10 6 ~10 7 cfu / mL, the inoculation volume of Monascus purple spore liqu...
Embodiment 1
[0048] ①Standardize the qualified raw milk so that the fat / protein ratio in the raw milk is 1.5:1;
[0049] ②Pasteurization, the sterilization condition is 73°C / 15s, cooled to 35°C;
[0050] ③ Add Flora Danica and STI-13 starter, add according to the amount of 10U / 100L, and add Monascus liquid fermentation spore liquid 10 8 cfu / L, with the pH dropping to 6.3 as the end point of fermentation acidification;
[0051] ④ Add rennet to control the curdling time at 7 minutes, then cut the curd, stir for 1 minute and then let stand for 10 minutes, repeat this operation 3 times;
[0052] ⑤ Discharge 30% whey, and then wash the curd with 30% sterile water with a temperature of 35°C, so that the pH of the final milk curd is 5.4;
[0053] ⑥ Put the milk curd into the mould, the temperature is controlled at 18°C; turn over once at 0.5h, 1h, and 1.5h respectively, and then remove the mould; soak the cheese block in 15% salt water, and the soaking time is controlled at 50min;
[0054] ⑦ T...
Embodiment 2
[0058] ①Standardize the qualified raw milk so that the fat / protein ratio in the raw milk is 1.8:1;
[0059] ②Pasteurization, the sterilization condition is 68°C / 25s, cooled to 39°C;
[0060] ③ Add Flora Danica and STI-13 starter, add according to the amount of 20U / 100L, and add Monascus liquid fermentation spore liquid 10 9 cfu / L, with the pH dropping to 6.4 as the end point of fermentation acidification;
[0061] ④ Add rennet to control the curdling time at 15 minutes, then cut the curd, stir for 1 minute and then let stand for 10 minutes, repeat this operation 3 times;
[0062] ⑤ Discharge 50% whey, and then wash the curd with 50% sterile water, so that the final milk curd pH value is 5.7;
[0063] ⑥ Put the milk curd into the mould, the temperature is controlled at 22°C; turn over once at 0.5h, 1h, and 1.5h respectively, and then remove the mould; soak the cheese block in 20% salt water, and the soaking time is controlled at 30min;
[0064] ⑦ Take the cheese out of the b...
