A kind of Medium of Bifidobacterium containing Fructus Fici extract
Technical field
The present invention relates to biological technical fields, and in particular to a kind of Medium of Bifidobacterium containing Fructus Fici extract.
Background technology
Bifidobacterium (Bifidobacterium) is the excrement by French scholar Tissier from breast milk nutrition youngster in 1899
In the Gram-positive bacillus of a kind of anaerobism isolated, end usually bifurcated, therefore named Bifidobacterium.Bifidobacterium is in human body intestines
Lactic acid and acetic acid can be generated after interior fermentation, the utilization rate of calcium, phosphorus, iron can be improved, there is treatment chronic diarrhea, treatment constipation, protect
Protect liver is dirty, prevention and cure of cardiovascular disease, the effect for improving lactose digestion etc..Bifidobacterium is distributed in the quantity of stomach and intestine with age level
Growth and reduce, it is breast milk nutrition youngster to be distributed most.It has been found that Bifidobacterium there are 32 hypotypes, contain Bifidobacterium
Up to 70 kinds of biological agent.Bifidobacterium infantis accounts for 60 the percent of total enterobacteriaceae, and 60 years old or more old man Bifidobacterium is only
Account for 7 percent points nine.
Ficus berry trees, edible rate are up to more than 92%, and fruit thin skin is seedless, and meat is soft, and flavor is sweet, tool
There are very high nutritive value and medical value, cultivation fig has very high economy, ecology and social benefit.First, no flower
Fruit has very high nutritive value, its fruit is rich in sugar, protein, amino acid, vitamin and mineral element.According to Shandong woods section
Measured, the soluble solid content of ripe fig is up to 24%, most of kind sugar contents between 15%~22%,
More than 1 times of many one, two generation fruit varieties.Containing 18 kinds of amino acid in fruit, wherein it is essential amino acid to have 8 kinds.
Secondly, fig has high medical value.
The content of the invention
The present invention overcomes Bifidobacterium proliferation rate it is low the technical issues of, a kind of bifid containing Fructus Fici extract is provided
Baccilus medium.
To solve the above problems, the present invention adopts the following technical scheme that:
A kind of Bifidobacterium culture containing Fructus Fici extract is made of the raw material of following mass concentration:Fig extracts
40~50g/L of object, 20~30g/L of carbon source, 10~30mg/L of multi-vitamins, 50~60g/L of colostrum, compound amino acid 10~
15g/L, 2~5g/L of potassium dihydrogen phosphate, 0.1~1g/L of magnesium chloride, 0.1~0.3g/L of calcium chloride, 0.2~0.4g/L of zinc sulfate,
0.1~0.3g/L of frerrous chloride, pH value 6.2~6.5;
Wherein, extract obtains the Fructus Fici extract by the following method:By fig drying to percent water
For 10%, then fig be crushed into 200 mesh sieves, the fig after crushing is placed in supercritical extraction reactor, with mass ratio
For 3:1 ethyl acetate and ethyl alcohol carries out supercritical CO for entrainer230~40min of extraction obtains Fructus Fici extract;It is described
Supercritical CO2The condition of extraction is:35 DEG C of extraction temperature, extracting pressure 40Mpa, CO2Flow velocity be 30L/min;The folder
Mass ratio with agent and fig is 10~15:100.
Wherein, in the Fructus Fici extract, not less than 80%, remaining makes a living the mass percentage of fig polysaccharide
Alkaloids and glucoside.
Wherein, the molecular weight of the fig polysaccharide is not higher than 5000.
Wherein, the carbon source is glucose, sucrose, the one or more of galactolipin.
Wherein, the compound amino acid is by lysine, threonine, leucine, isoleucine, valine, methionine, color
Propylhomoserin, phenylalanine, cystine, cysteine, glycine, histidine, glutamic acid, arginine composition.
Wherein, the multi-vitamins are by vitamin A, vitamin C, vitamin B1, vitamin B12, vitamin E group
Into.
Wherein, fig drying is dried using microwave drying mode;The microwave power is 300~500W.
Colostrum is the milk in 3 days after cow calving, and nutritional ingredient is compared with ordinary milk, containing compared with high protein
Matter, and fat and sugar content is then relatively low.Colostrum is also containing substantial amounts of immune and growth factor, such as immunoglobulin, newborn iron egg
In vain, lysozyme, insulin-like growth factor, epidermal growth factor etc..Colostrum provides abundant nitrogen source for Bifidobacterium, simultaneously
Also contribute to the growth of hyperbolic bacillus containing abundant immune and growth factor in colostrum.
Bifidobacterium nutritional requirement is higher, and culture medium need to contain abundant amino acid, vitamin, glucide and buffer salt
Class, and in addition to basic nutritional need, also need addition bifid proliferation factor, such as carbohydrate containing N-Acetyl-D-glucosamine, egg
White matter is through proliferation factor in enzyme, glycoprotein, glycopeptide and plant extracts etc..
In existing technology, generally mostly using oligosaccharide as proliferation factor, including isomalto-oligosaccharide glucose, fructose
Oligosaccharide, sucrose oligosaccharide, cow's milk oligosaccharide, soyabean oligosaccharides, galactose oligosaccharides etc..
The present invention has the advantages that compared with prior art:
(1) Fructus Fici extract contained in culture medium of the invention is Bifidobacterium proliferation factor, while fig carries
The low-molecular polysaccharide in object is taken to be alternatively arranged as carbon source to be utilized by bifidobacterium fermentation, culture medium is using colostrum as main nitrogen, together
Vitamin, amino acid, inorganic salts and the suitable pH value that Shi Hanyou enriches, culture medium of the invention are greatly improved bifid bar
The appreciation rate of bacterium, bifidobacterium growth are bred.
(2) Fructus Fici extract of the invention uses supercritical CO2It is extracted, wherein using using mass ratio as 3:1
Ethyl acetate and ethyl alcohol be entrainer, use ethyl acetate, ethyl alcohol compared to single as entrainer, ethyl acetate and ethyl alcohol
Compound entrainer polarity is more preferable, especially good to the dissolubility of low-molecular polysaccharide to the polarity polysaccharide of fig kind, improves
The content of proliferation factor in Fructus Fici extract.
(3) it is low-molecular polysaccharide without melon and fruit polysaccharide to contain in the Fructus Fici extract in the present invention, is had to Bifidobacterium
There is higher proliferation function.
Specific embodiment
With reference to embodiment and experiment, the invention will be further described.
