Description

A kind of sea-buckthorn fermented product and preparation method thereof
Technical field
The present invention relates to a kind of fermented product, particularly relate to a kind of sea-buckthorn fermented product and preparation method thereof.
Background technology
Sea-buckthorn is a kind of fallen leaves property shrub, and another name vinegar willow, acid thorn etc., be mainly distributed in the ground such as China North China, northwest, southwest.Containing abundant nutriment and bioactivator in sea buckthorn fruit; and Vitamin C content is high; have the laudatory title of the king of vitamin C, sea buckthorn fruit can be used as medicine, and it can reduce cholesterol, protection cardiovascular system, improves immunity, promote blood vigor, stomach strengthening and digestion promoting etc.
At present, a small amount of relevant report sea-buckthorn being processed into beverage is had.Such as, notification number be CN103263056A patent discloses a kind of rock sugar fruit drink containing sea-buckthorn, it adds sulfur dioxide after sea-buckthorn is squeezed out juice, pectinase enzymatic hydrolysis, add rock sugar again, sweetener, acid, vitamin C allocate, though there is certain health care, but the effective nutritional labeling of majority do not discharged in sea-buckthorn, and additive is too much, do not give full play to the local flavor of fructus hippophae itself, the simultaneously existence of additive also counteracts that the absorption of human body for wherein nutritional labeling.
Summary of the invention
The invention provides a kind of sea-buckthorn fermented product and preparation method thereof, for solving the technological deficiencies such as sea-buckthorn series products nutritional labeling of the prior art is single, taste is common, health care is limited.
The invention provides a kind of preparation method of sea-buckthorn fermented product, comprise the steps:
1) squeeze sea-buckthorn and go out juice, taking juice;
2), after adding medium component in described juice, access Leuconostoc mesenteroides carries out the first fermentation, when the pH value of zymotic fluid reduces by more than 0.5, and the content of reducing sugar of zymotic fluid lower than 1.5% time terminate described first fermentation, obtained first zymotic fluid;
3) to pH value be 4.5 ~ 6 fruits and vegetables liquid in add pectase and carry out enzymolysis processing, obtained enzymolysis fruits and vegetables liquid;
4) after adding medium component in described enzymolysis fruits and vegetables liquid, access compound lactobacillus carries out the second fermentation, terminates described second fermentation, obtained second zymotic fluid when the pH value of zymotic fluid reduces by more than 0.5; Wherein, described compound lactobacillus is selected from more than four kinds in streptococcus thermophilus, Lactobacillus delbrueckii, lactobacillus acidophilus, Pediococcus pentosaceus, Lactobacillus casei, lactobacillus paracasei, Lactobacillus rhamnosus, Lactobacillus plantarum, lactobacillus fermenti, Pediococcus acidilactici and leuconostoc lactis;
5), after adding medium component in described second zymotic fluid, access mulriple yeasts carries out the 3rd fermentation, when zymotic fluid total sugar content lower than 2% time terminate described 3rd fermentation, obtained 3rd zymotic fluid; Wherein, what described mulriple yeasts was selected from rice wine yeast, brewer's yeast, saccharomyces sake and fruit wine and wine yeast is two or more;
6) by centrifugal after described first zymotic fluid and described 3rd zymotic fluid mixing, after centrifuged supernatant homogeneous, sterilizing, obtained sea-buckthorn fermented product.
In the preparation process in accordance with the present invention, described Leuconostoc mesenteroides can select Leuconostoc mesenteroides dextran subspecies (L.mesenteroides subsp.dextranicum) or leuconostoc mesenteroides sub species cremoris (L.mesenteroides subsp.cremoris), and each bacterium of the present invention can adopt the mode of bacterium powder or bacterium liquid to use.When adopting bacterium powder, the viable count of described each lactic acid bacteria bacterium powder can be 10 9about CFU/g, the viable count of each saccharomycete bacterium powder can be 10 10about CFU/g.In addition, the inoculum concentration of described Leuconostoc mesenteroides (bacterium powder) can be 0.05 ~ 0.2%, such as 0.1%, the inoculum concentration of described compound lactobacillus (bacterium powder) can be 0.05 ~ 0.2%, such as 0.1%, the inoculum concentration of described mulriple yeasts (bacterium powder) can be 0.01 ~ 0.02%.When adopting bacterium liquid, the viable count and the inoculum concentration that can refer to above-mentioned bacterium powder are inoculated.Each bacterial strain conventionally can activate according to needs before use.
The present invention does not make considered critical to described sea-buckthorn kind, and it can be Hippophne, Inner Mongol sea-buckthorn, also can be Chinese sea buckthorn.In concrete scheme of the present invention, fresh Chinese sea buckthorn can be adopted as raw material, its moisture content is 40 ~ 50%.Further, described sea-buckthorn squeezing is to 40 ~ 80 orders.The pH of described sea-buckthorn squeezing gained juice is 4.5 ~ 6.
In the present invention, described medium component can comprise carbon source, nitrogenous source, inorganic salts, trace element etc., and those skilled in the art can select according to the concrete bacterial strain cultivated or compound bacteria the medium component that is suitable for.In concrete scheme of the present invention, described medium component comprise in sugar, peptide, inorganic salts and surfactant one or more, in wherein said peptide, mean molecule quantity is less than gross mass content >=80% of the component of 1000Da.
Namely, the present invention additionally provides a kind of fluid nutrient medium for Leuconostoc mesenteroides fermentation on the other hand, it comprises sea-buckthorn juice, sugar, peptide, inorganic salts and surfactant, wherein the mass content of sugar in described juice can be 5 ~ 10%, the mass content of peptide in described juice can be 0.3 ~ 0.8%, the mass content of inorganic salts in described juice can be 0.1 ~ 0.3%, and the mass content of surfactant in described juice can be 0.01 ~ 0.1%; This sea-buckthorn juice is by obtaining after sea-buckthorn squeezing.
Again on the one hand, present invention also offers a kind of fluid nutrient medium fermented for compound lactobacillus and/or mulriple yeasts, it comprises enzymolysis fruits and vegetables liquid, sugar, peptide, inorganic salts and surfactant, wherein the mass content of sugar in described enzymolysis fruits and vegetables liquid can be 5 ~ 10%, the mass content of peptide in described enzymolysis fruits and vegetables liquid can be 0.3 ~ 0.8%, the mass content of inorganic salts in described enzymolysis fruits and vegetables liquid can be 0.1 ~ 0.3%, and the mass content of surfactant in described enzymolysis fruits and vegetables liquid can be 0.01 ~ 0.1%; This enzymolysis fruits and vegetables liquid by pH value be 4.5 ~ 6 fruits and vegetables liquid in add pectinase enzymatic hydrolysis obtain.
