Probiotic freeze-dried powder is an active microbial preparation processed by freeze-drying technology, mainly containing beneficial bacteria such as lactic acid bacteria and bifidobacteria.Application of probiotic freeze-dried powder:1.The application of probiotic freeze-dried powder in skin repair after photoelectric surgery;2.Application of probiotic freeze-dried powder in improving skin barrier function;3.The application of probiotic freeze-dried powder in alleviating skin inflammation.

Principles for optimizing the cultivation process of probiotics freeze-dried powder for medical beauty purposes:1.Bifidobacterium culture temperature,36 - 38℃ (growth temperature;2.The temperature fluctuation range should ensure that the temperature fluctuation range is ≤±1℃, avoid bacterial stress response3.pHValue control range controlpHValue in6.5 - 7.0Within the scope, avoid damage to bacterial cells in acidic or alkaline environments;4.Centrifugal speed4000 - 6000 rpm；5.Lactic acid bacteria cultivation temperature30 - 43℃；5.N₂Nano bubble water action, usingN₂Nano bubble water can promoteLactobacillus acidophilusGrowth and improvement rate can reach51.1%；6.Anaerobic cultivation conditions are crucial for anaerobic bacteria such as Bifidobacterium, and centrifugation time is crucial15 - 20minute.

Characteristics of probiotic freeze-drying machine: The equipment is304Stainless steel material, stainless steel door with mirror, fast freeze-drying production efficiency, continuous production, good stability, and the whole machine can be used15Over years old, we provide screening of probiotic freeze-drying protectants, optimization of freeze-drying processes, and scaling up of freeze-drying production.
