Embodiment Construction

[0025] A preparation process of a probiotic powder provided by the present invention is described in detail with reference to the drawings in the embodiments of the present invention.

[0026] A kind of probiotic powder preparation process, comprises the following steps:

[0027] Step 1: Take out the probiotic strains from the liquid nitrogen tank, and transfer the isolate to a fermenter for fermentation in a sterile state;

[0028] Step 2: Sampling and testing every 32 minutes, and adding culture medium;

[0029] Step 3: Use ceramic membrane filtration technology to concentrate the probiotic strains by 25 times, and observe the concentration of the bacteria liquid at the bottom of the container;

[0030] Step 4: Use the freeze-intervention treatment device to reduce the water content in the concentrated probiotic strains after packaging, and finally freeze-dry the concentrated probiotic strains into granules through vacuum drying equipment;

[0031] Step 5: Grinding the gra...

Abstract

The invention belongs to the technical field of probiotic powder processing, particularly relates to a probiotic powder preparation process, and aims to perform low-temperature pretreatment on probiotic powder. The process comprises the following steps: step 1, taking out a probiotic strain from a liquid nitrogen box, and transferring an isolate into a fermentation tank for fermentation treatment in a sterile state; 2, sampling detection is conducted every 30-35 min, and a culture solution is added; step 3, concentrating the probiotic strain by 20-30 times by using a ceramic membrane filtration technology, and observing the concentration amount of the bacterial liquid at the bottom of the container; step 4, reducing the moisture content in the sub-packaged concentrated probiotic strains through a freeze-drying pre-treatment device, and finally freeze-drying the concentrated probiotic strains into granules through vacuum drying equipment; step 5; grinding the granular probiotic material into powder, sieving with a 300-mesh sieve, and packaging at low temperature; the freeze-drying pretreatment device comprises a supporting frame, and a freeze-drying treatment tank and a plurality of rotating rollers are rotationally connected to the supporting frame and used for supporting the bottom of the freeze-drying treatment tank.

Description

technical field [0001] The invention belongs to the technical field of probiotic powder processing, in particular to a preparation process of probiotic powder. Background technique [0002] Probiotic powder is beneficial to human health and can maintain intestinal health and balance, mainly including bifidobacteria and lactobacilli, which have the functions of intestinal health, immunity enhancement, and regulation; probiotic powder is mainly achieved through freeze-drying technology Storage effect; freeze-drying technology has less damage to biological tissue and cell structure and characteristics, making it quickly enter a dormant state, effectively protecting the stability of active ingredients in many heat-sensitive products such as probiotics, but the existing freeze-drying technology is for The processing time of the probiotic powder is long, and it is usually carried out in a vacuum state. Long-term freeze-drying treatment will cause damage to the probiotic material, ...
