Embodiment 1

[0022] A preparation method of a solid probiotic preparation, which specifically comprises the following steps:

[0023] 1) centrifuging the probiotic fermentation broth at a centrifugation speed of 8000 rpm and a centrifugation time of 3 minutes to obtain probiotic cells, suspending the probiotic cells in 0.9% normal saline to obtain a probiotic cell suspension;

[0024] 2) Add betaine and hydroxyproline to the probiotic cell suspension at room temperature so that the final concentration of betaine is 0.1%, the final concentration of hydroxyproline is 0.06%, and the temperature of the control cell suspension is 0 ℃ for 2 hours, adjust the temperature to -15 ℃ for 40 minutes; adjust the temperature to -30 ℃ for 4 hours; restore the temperature to room temperature;

[0025] 3) Add 4% by weight sorbitol and 4% by weight glucose to the probiotic cell suspension, put it into a vacuum freeze dryer and freeze-dry, and control the freeze-drying temperature to -25°C-- 35°C, freeze-dr...

Embodiment 2

[0028] A preparation method of a solid probiotic preparation, which specifically comprises the following steps:

[0029] 1) centrifuging the probiotic fermentation broth at a centrifugation speed of 10,000 rpm and a centrifugation time of 5 minutes to obtain probiotic cells, suspending the probiotic cells in 0.9% normal saline to obtain a probiotic cell suspension;

[0030] 2) Add betaine and hydroxyproline to the probiotic cell suspension at room temperature so that the final concentration of betaine is 0.2%, the final concentration of hydroxyproline is 0.12%, and the temperature of the control cell suspension is - 5°C for 4 hours, adjust the temperature to -20°C for 60 minutes; adjust the temperature to -40°C for 6 hours; return to room temperature;

[0031] 3) Add 6% by weight sorbitol and 6% by weight glucose of the probiotic cell suspension to the probiotic cell suspension, put it into a vacuum freeze dryer for freeze-drying, control the freeze-drying temperature to be -3...

Embodiment 3

[0034] A preparation method of a solid probiotic preparation, which specifically comprises the following steps:

[0035] 1) Centrifuge the probiotic fermentation broth at a centrifugation speed of 9000 rpm and a centrifugation time of 4 minutes to obtain probiotic cells, suspend the probiotic cells in 0.9% normal saline to obtain a probiotic cell suspension;

[0036] 2) Add betaine and hydroxyproline to the probiotic cell suspension at room temperature so that the final concentration of betaine is 0.15%, the final concentration of hydroxyproline is 0.09%, and the temperature of the control cell suspension is - 5°C for 3 hours, adjust the temperature to -18°C for 50 minutes; adjust the temperature to -35°C for 5 hours; return to room temperature;

[0037] 3) Add 5% by weight sorbitol and 5% by weight glucose to the probiotic cell suspension, put it into a vacuum freeze dryer for freeze-drying, control the freeze-drying temperature to -30°C, freeze The drying time is 22 hours. ...

Abstract

The invention relates to a preparation method of a solid probiotic preparation, and belongs to the field of dairy product manufacturing. In order to overcome the shortages that in the prior art, the death rate of cells in a conventional freeze-drying technology is high and the finished products have safety hazard, the invention provides a preparation method of a solid probiotic preparation and a solid probiotic preparation. According to the preparation method, betaine and hydroxyproline are added into probiotic suspension, then the temperature of the probiotic suspension is gradually reduced so as to enhance the anti-freeze performance of probiotics; then glucose and sorbitol are added, and finally freeze-drying is performed to obtain the solid probiotic preparation. The survival rate of probiotics in the prepared solid probiotic preparation can reach 85% or more and is obviously better than that of probiotics in a solid probiotic preparation prepared by a conventional technology. Thepreparation method has the advantages of simple steps and short processing time, and is suitable for popularization and application.

Description

technical field [0001] The invention relates to a preparation method of a solid probiotic preparation, which belongs to the field of dairy product manufacturing. Background technique [0002] Probiotics are a class of active microorganisms that are beneficial to the host. They are a general term for active beneficial microorganisms that colonize the human intestinal tract and reproductive system and can produce definite health effects, thereby improving the host's micro-ecological balance and exerting beneficial effects. Beneficial bacteria or fungi in humans and animals mainly include Clostridium butyricum, Lactobacillus, Bifidobacterium, Actinomycetes, and yeast. At present, the most powerful products researched in the world are mainly compound active probiotics composed of the above-mentioned various microorganisms, which are widely used in the fields of bioengineering, industry and agriculture, food safety, and life and health. [0003] Reasonable and effective probioti...
