Description

A kind of food materials are used for the method for probiotic's culture and its application
Technical field
The present invention relates to a kind of bacterium preparation method and applications, are used for probiotic's culture more particularly, to a kind of food materials Method and its application.
Background technology
Probio, mono- words of English probiotics are derived from by Greek " for live ", are translated into " for life ", are Viable bacteria containing physiologically active, when being taken in after appropriate quantity through oral or other administering modes by body, can be colonized in Host simultaneously improves host's microecological balance, so as to play beneficial effect.Recent studies indicate that, the bacterium in human body is up to Bacterium in kind more than 1000, particularly intestines and stomach is enriched the most, accounts for whole body micro-ecological bacterial sum 80% or so, is human body cell 10 times, it is described as " second genome " of the mankind.These bacteriums contribute to human consumption's food, produce vitamin to prevent food The disease induced by middle bacterium, while stimulating immune system.With going deep into for research, find enteric microorganism in many chronic diseases In disease and symptom, such as inflammation, obesity, diabetes, also cancer etc. also play key effect.The quantity of microorganism and gene dosage Surprising, the strong health for affecting the mankind.These are found to be probiotic products in food, health products, medicine, cultivation, environment, health The application in the fields such as articles for use brings huge motive force.At present, probio is widely used in Yoghourt, sour milk beverage, prebiotic In the products such as bacteria powder, animal feed, environmental improvement, relatively complete and ripe probio industry is defined.
The production of probio is mainly using solid fermentation and big tank liquid deep layer fermenting method.Solid fermentation method is probio Being inoculated on solid medium carries out fermented and cultured, Chinese invention patent (publication number:104830711 A of CN) invent disk Installation for fermenting solid fermentation bacillus amyloliquefaciens, fermentation time are usually 48h~72h.Chinese invention patent (publication number:CN 105132321A) using the culture medium by material compositions such as wheat bran and dregs of beans, inoculation VREF carries out solid state fermentation, dries and produces Viable bacteria content in product is up to 3.8 × 1010CFU/g.Similar also has Chinese patent (publication number:CN 101555510B;CN 101555511B;CN 103421710B;CN 102907563B;CN 103289937B;CN 1212391C) using dregs of beans, The agricultural wastes such as wheat bran, corncob, rice bran, peanut shell, starch, corn flour, turf or the solid that agricultural product are main component Culture medium, microbe inoculation carry out high density fermentation, and the viable count in product is essentially 1011CFU/g.This kind of product is due to adopting Make culture medium with a large amount of agricultural wastes or agricultural product, be mainly used in animal feed or carry out the production of the metabolites such as medicine, training Support after terminating, great majority cannot be used directly for the production of the products such as human food, health products and medicine, need more follow-up locating Science and engineering skill could prepare Related product.Additionally, although solid fermentation simple production process, small investment, easily receive miscellaneous bacteria simultaneously again Pollution, unstable product quality, the longer shortcoming of fermentation time.Big tank liquid deep layer fermenting method is to adopt modern fermentation technique, Probio is inoculated in bioreactor and is aerated culture, with being easily controlled thalline content, the stable spy of product quality Point.Chinese invention patent (publication number:105018408 A of CN) add rutin raising rhamnose bacterium lactobacillus in the medium Fermenting speed and the viable count of probio, the maximum viable count of the probiotics fermention liquid that probiotics fermention growth 24h is obtained are reachable Arrive about 109CFU/mL.But such method is higher to technical merit requirement, with respect to solid fermentation investment height, subsequent concentration and separation The high cost of target product.It is well known that fermentation Downstream processing has conclusive effect to the quality of product, thus downstream adds Separation and purifying cost in work accounts for the major part in fermentation totle drilling cost.Therefore, simplify zymotechnique, stabilized product quality is Important technological problems in probio exploitation and market.
Content of the invention
It is an object of the invention to overcoming the shortcoming of prior art, there is provided a kind of method that food materials are used for probiotic's culture And its application.The inventive method is in the culture medium containing the somatomedin for promoting growth of probiotics breeding to add porous Food materials, inoculation probio simultaneously ferment, and porous food materials overcome traditional agriculture discarded object or agricultural product are difficult to directly eat not Foot part, and good nutrition and enrichment carrier is provided to growth breeding.After culture terminates, direct separation of solid and liquid is simultaneously done Dry, high density, the high activity state of aggregation probio of edibility is prepared, food, food additives, health products are can be widely used for Exploitation with products such as medicine.
The technical solution used in the present invention is as follows:
First, a kind of method that food materials are used for probiotic's culture:
Fermentation Flour product, is obtained foaminess food materials, is broken into particle.
The fermentation Flour product, be flour, ground rice, corn flour and various coarse cereal powders make obtain bread, cake, steamed bun The foaminess food materials such as head, rice cake and steamed sponge cake.
