Description

Probiotic bacteria embedded granule and preparation method thereof

The invention relates to a probiotic bacteria embedded particle and a manufacturing method thereof, in particular to an embedding particle for embedding probiotic bacteria by a fungus hyphae and a manufacturing method thereof.

Probiotics generally refer to bacteria that use carbohydrates for fermentation to produce large amounts of lactic acid. Probiotics prevent the invasion of pathogens by attaching to the gut of the host and have positive benefits for the host. The probiotics commonly found on the market today are lactic acid bacteria and yeasts, while the probiotics are mainly liquid, powder or hard capsules. Among them, since the product type of probiotics will affect its efficacy, it plays an important part in development and production.

Taking lactic acid bacteria as an example, for example, Republic of China Invention Patent Publication No. 587098, discloses a lactic acid bacteria capable of improving immunity, comprising any one or more of the following biologically pure cultures stimulating an immunological concentration: Lactobacillus rhamnosus HN001 CCRC 910107; Lactobacillus licheniformis HN067 CCRC 910108; Bifidobacterium lactis HN019 CCRC 910110 or Lactobacillus acidophilus HN017 CCRC 910109, and a physiologically acceptable excipient or diluent, wherein the excipient or The diluent is a food product, and the food is fermented milk, yogurt, cheese, dairy drink or milk powder. Or, as disclosed in the Chinese Patent Publication No. I451871, a food composition for inhibiting an inflammatory reaction, comprising: a plurality of strains of lactic acid bacteria comprising Lactobacillus salivarius AP-32 strain, accession number BCRC 910437, road Lactobacillus reuteri TE-33 strain, accession number BCRC 910441, Lactobacillus acidophilus F-1 strain, accession number BCRC 910469 and Lactobacillus rhamnosus CT-53 strain, registration number BCRC 910468, wherein the lactic acid bacteria strain has stomach acid, bile salt and mold inhibitor Clotrimazole tolerance; and a physiologically acceptable excipient or a diluent, wherein the excipient or the dilution The agent is fermented milk, yogurt, cheese, milk powder for dairy drinks, tea or coffee. In the above prior art, the lactic acid bacteria dosage form is a liquid or powder which is not embedded, because the lactic acid bacteria are sensitive to the pH of the environment, and the stomach acid and bile of the human body have a bactericidal effect, and the un-encapsulated lactic acid bacteria enter the human body and the bacteria body. It is easy to be destroyed, but it can not exert its proper curative effect. Secondly, due to the lack of embedding, the stability of lactic acid bacteria is insufficient, and the number of viable bacteria is easily reduced, resulting in short storage period and long-lasting survival.

In view of the above shortcomings, another lactic acid bacteria embedded in capsules, such as the Republic of China Invention Patent Publication No. M384660, discloses a LS66 capsule combination structure capable of inhibiting the growth of excess fat in the body, comprising a body, more than one LS66 spore lactic acid bacteria and one a coating layer, the body comprises an upper capsule and a lower capsule, and the upper capsule and the lower capsule are combined to form an accommodating space therein, and the LS66 spore lactic acid bacteria is filled in the accommodating space, and the coating layer is coated Deployed on the inner surface of the body, wherein the coating layer is an activator. However, the hard-capsule-embedded lactic acid bacteria can protect the cells from the acidic stomach environment, but the hard capsules are not easily dissolved in the intestinal tract, making the timing of releasing the cells unstable, and also having the problem of being inferior.

In addition to the above product types of liquids, powders and hard capsules, there are also crystal spheres used as materials for coating probiotics.
