Application of freeze-drying machine in the processing of probiotic freeze-dried powder

Freeze dryer is the abbreviation of vacuum freeze dryer. It uses vacuum freeze drying technology to freeze liquid probiotic substances containing water into a solid state at low temperature. Then, in a vacuum environment, the solid ice is sublimated into water vapor to remove it, obtaining probiotic freeze-dried powder with a water content of less than 1%.After being processed by a freeze-drying machine, the probiotic freeze-dried powder retains its original active ingredients and nutritional components, making it easy to store and transport at room temperature for a long time. Today's introductionApplication of freeze-drying machine in the processing of probiotic freeze-dried powder.

Probiotics areBeneficial active microorganisms，Promoting nutrient absorption and maintaining intestinal health by regulating the immune function of the host mucosa and system, or by regulating the balance of gut microbiota.haveIntestinal function, relieves lactose intolerance symptoms, promotes nutrient absorption in the body, and can adjust microecological imbalances， Enhance human immunityWaiting for action.According to international standardsProbioticNeed to belivesexuallyHaving a sufficient quantityofOnly microbial strains that are beneficial to the host can be called probiotics. So activity is the key to probiotics. Only strains that can survive after passing through the digestive tract environment of the human body, such as gastric acid and bile, can reach the large intestine and exert their effectsrole，And at least it containsOne million is effective.becauseProbioticsVery sensitive to heat, decidefinishProbiotics can only be obtained through freeze-drying equipmentPerform drying processing.Through freeze-drying technology, probiotic biological tissues and cells can be processed，Reduce damage to the structure and characteristics, thereby protecting the stability of the active ingredients in dry thermosensitive products such as probiotics.Ensure the preservation of nutrients and microorganisms.
