Embodiment 1

[0022] Inoculate Rhizopus oryzae and Aspergillus oryzae on potato agar solid slant medium respectively, and culture them purely at 28°C until the slant is covered with hyphae. Inoculate the mycelium grown on the potato agar solid slant medium into the solid bran medium respectively, cultivate at 28°C until the surface is covered with hyphae, and inoculate the mycelia into the solid bran medium at 28°C Continue to cultivate until the surface of the culture medium is covered with hyphae, inoculate into steamed glutinous rice according to the ratio of Rhizopus:Aspergillus=7:3, the inoculum size is 0.5%, after stirring evenly, ferment for 2 days at 32°C. Then add sterile water with a quality 4 times that of dried glutinous rice, and continue to ferment for 8 days. Suction filter the fermented liquid, and the obtained light yellow clear liquid is the coagulant.

Embodiment 2

[0024] Mucor rousei and Aspergillus oryzae were inoculated on potato agar solid slant medium respectively, and cultured at 15°C until the slant was covered with hyphae. Inoculate the mycelia grown on the potato agar solid slant medium into the potato agar solid slant medium respectively, cultivate at 15°C until the surface is covered with hyphae, inoculate the mycelium into the solid bran medium at 15 Continue to cultivate at ℃ until the surface of the culture medium is covered with hyphae, inoculate into steamed glutinous rice according to the ratio of rhizopus: aspergillus = 8:2, the inoculation amount is 0.5%, after stirring evenly, ferment at 32 ℃ for 2 days. Then add sterile water with a quality 4 times that of dried glutinous rice, and continue to ferment for 8 days. Suction filter the fermented liquid, and the obtained light yellow clear liquid is the coagulant.

Embodiment 3

[0026] Inoculate Rhizopus oryzae and Aspergillus oryzae on solid bran medium respectively, culture at 20°C until it is covered with mycelia, inoculate the mycelium into solid bran medium and expand culture at 20°C until the solid bran medium is covered with bacteria Silk, continue to be inoculated into the solid bran medium and expand and cultivate to the surface of the medium to be covered with mycelia at 20°C, according to the ratio of Rhizopus: Aspergillus=5:5, inoculate to steamed glutinous rice, inoculum size 1.0%, stir After uniformity, ferment for 1 day at 28°C. Then add sterile water with twice the quality of dried glutinous rice, and continue to ferment for 6 days. Suction filter the fermented liquid, and the obtained light yellow clear liquid is the coagulant.

Abstract

The present invention provides a preparation method of cheese. Said preparation method includes the following steps: regulating total dry content of fresh milk to 13-20% of its mass, homogenizing, sterilizing for 5-15 min at 85-95deg.C, adding milk coagulant into the milk according to the ratio of milk coagulant: milk=1:7-10(v / v), placing the milk mixture into an environment with 40-80deg.C and making fermentation for 30-60min, then post-maturing for 12-24h at 4-8deg.C so as to obtain the invented cheese. Besides, said invention also provides the milk coagulant used in said preparation method.

Description

technical field [0001] The invention relates to the field of food, in particular to a method for preparing cheese. Background technique [0002] The production and consumption of palace cheese has a history of hundreds of years in our country. Its production method is to first ferment the curd agent with a starter, then add the curd agent to milk in proportion, heat and ferment for a certain period of time, and obtain a dairy product with a tissue state similar to coagulated yogurt and tofu flower. However, the traditional production process is complicated and time-consuming, and the cheese storage period is short, and the cheese tissue is fragile and inconvenient to transport, so that the product can only be hand-made cheese and sold in specialized stores, which limits the industrial production and sales of the product. Contents of the invention [0003] (1) Technical problems to be solved [0004] The invention aims at proposing a method for improving the tissue state ...
