Description

A kind of gingko functional red yeast rice and its process for solid state fermentation and application
Technical field
The invention belongs to biofermentation product technique fields, more particularly to a kind of gingko functional red yeast rice and its solid state fermentation Methods and applications.
Background technique
Red yeast rice is traditional food and Chinese medicine, successive dynasties a variety of herbal bibliographys, such as Compendium of Material Medica, " herbal solutions " and " this The standby medicine of grass " etc. it is on the books to red yeast rice.Red yeast rice is sweet in flavor and warm in property, nontoxic, return heart, liver, spleen, large intestine channel, has promoting blood circulationization addiction, invigorating the spleen It helps digestion, dehumidifying eliminate the phlegm function, cures mainly dizziness, headache, fat more phlegm, trusted subordinate have a pain, traumatic injury, women's post partum longtime lochia etc. Disease.It has been investigated that a variety of effective active matters such as K containing Monacolin, γ-aminobutyric acid and ergosterol in red yeast rice, have The multiple functions such as antibacterial, anti-corrosion, health care, thus it is widely used in food industry.
Gingko is being commonly called as ginkgo kernel, and gingko health macrobiosis is listed in imperial tribute in the Song Dynasty.Remember according to Compendium of Material Medica Carry: " prepared food warm lung, QI invigorating, relieving asthma and cough, reduce just, only gonorrhoea;Eat drop phlegm, disinfection raw ".Modern science proves: ginkgo kind Benevolence contains the centerings effective component such as GINKGO BILOBA EXTRACT, ginkgolic acid, and having reduces serum cholesterol, coronary artery dilator and antibacterial kills Bacterium effect, is a kind of dual-purpose of drug and food resource.
The production of existing red yeast rice is led mostly using rice as primary raw material, but since rice price in recent years is constantly soaring It causes red yeast rice production cost to be continuously increased, therefore is badly in need of finding new raw material substitution rice.In addition, with people's health requirement It is higher and higher, it develops a kind of with will also have wide market application prospect rich in the novel red yeast rice of functional component.
Summary of the invention
The technical issues of solution: the present invention provides a kind of gingko functional red yeast rice and its process for solid state fermentation and applications.With Red yeast rice is leavening, and gingko functional red yeast rice is dried to obtain after liquid seed culture, solid state fermentation.Gingko produced by the present invention Functional red yeast rice also containing the Monacolin K in red yeast rice, while having stronger removing both containing the phenolic compound in gingko DPPH and ABTS free radical ability is a kind of functional food raw material for integrating nutrition and health care.
Technical solution: a kind of gingko functional red yeast rice process for solid state fermentation, using red yeast rice as leavening, through liquid seed culture Afterwards, it is inoculated in ferment in gingko solid medium and be made.
A kind of gingko functional red yeast rice process for solid state fermentation includes the following steps: prepared by (1) liquid seed culture medium: pressing Column group assignment system fluid nutrient medium, gingko full powder 2wt.%-6wt.%, ammonium chloride 0.2wt.%-0.4wt.%, magnesium sulfate 0.05wt.%-0.08wt.% adds water to 100%, in 121 DEG C of sterilizing 20min;(2) it liquid seed culture: is trained by liquid seed The 5wt.%-8wt.% for supporting base is inoculated with red yeast rice, is placed in rotary shaker 160rpm, and cultivation temperature is 28 DEG C, and culture 48h obtains red yeast rice Liquid seed;(3) prepared by gingko solid medium: fresh or extra dry white wine fruit squeezes to no whole grain, presses through boiling to no hard core Following component adds ammonium sulfate 0.1wt.%~0.5wt.%, ammonium chloride 0.1wt.%~0.5wt.%, sulphur with gingko ratio is accounted for Sour magnesium 0.01wt.%~0.10wt.%;(4) gingko functional red yeast rice solid state fermentation: by the 10wt.%- of gingko solid medium 20wt.% is inoculated with red yeast rice liquid seed fermentation, and fermentation temperature is 26~32 DEG C, dry after the 15d that ferments, and it is red to obtain gingko function It is bent.
Gingko functional red yeast rice made from above-mentioned process for solid state fermentation.
Above-mentioned gingko functional red yeast rice is preparing the application in food additives and functional food raw material.
Above-mentioned production technology preparation gingko functional red yeast rice is rich in phenolic compound and Monacolin K, while having relatively strong Removing DPPH and ABTS free radical ability, can be used as food additives and functional food raw material application.
The utility model has the advantages that (1) using red yeast rice as leavening, using gingko powder as carbon source in seed culture medium, optimizes red yeast rice Bacterium fermenting property enables subsequent gingko solid state fermentation quickly to carry out;(2) gingko in the present invention is using cooking extrusion to nothing The technique of whole grain, gingko is completely broken in extrusion process, is conducive to Monascus fast-growth;(3) gingko in the present invention Ammonium sulfate, ammonium chloride and magnesium sulfate are added in solid-state fermentation culture medium, this 3 kinds of inorganic salts are conducive to gingko functional red yeast rice MonacolinK makes its content reach maximum, at the same do not reduce gingko red yeast rice aldehydes matter content again and remove DPPH and ABTS free radical ability.
