[technical field]
The present invention relates to food processing technology fields, and in particular to a kind of Chinese yam jujube composite fermented beverage and its preparation side
Method.
[background technique]
Chinese yam is also known as Chinese yam, white Chinese yam, has effects that nourishing is strong, aid digestion, holds back abnormal sweating, antidiarrheal, cures mainly spleen deficiency abdomen
It rushes down, cough due to deficiency of the lung, diabetes are quenched one's thirst, oliguria frequency, spermatorrhea, women's leukorrhagia and dyspeptic chronic enteritis.Jujube, You Ming great
Jujube, belong to Angiospermae, Dicotyledoneae, Rhamnales, Rhamnaceae, zizyphus plant, vitamin content is very high, has
The good reputation of " natural vitamin ball ", has effects that nourishment for vitality, enriches blood.
China is large agricultural country, Chinese yam and jujube it is resourceful, using Chinese yam and red jujube for fermented beverage, to raising
Its postpartum added value is of great significance.But current fermented beverage has that stability is not high mostly.
[summary of the invention]
Goal of the invention of the invention is: in view of the above problems, providing a kind of Chinese yam jujube composite fermented beverage
And preparation method thereof.Chinese yam jujube composite beverage of the invention is added to special emulsion stabilizer, effectively improves beverage
Stability, storage effect is good, while improving the aesthetic quality of beverage.
To achieve the goals above, The technical solution adopted by the invention is as follows:
A kind of Chinese yam jujube composite fermented beverage, the Chinese yam jujube composite fermented beverage include the raw material of following parts by weight
Component: 20-50 parts of Succus Rhizoma Dioscoreae, 30-80 parts of jujube juice, 0.01-0.03 parts of emulsion stabilizer and 1.5-3 parts of white granulated sugar;The cream
Change the raw material components that stabilizer includes following parts by weight: 5-8 parts of sucrose fatty ester, 3-8 parts of Arabic gum, soya-bean polypeptides 1-3
Part, 1-2 parts of astragalus polyose and 0.5-1 parts of phosphate.
Further, the Chinese yam jujube composite fermented beverage includes the raw material components of following parts by weight: 35 parts of Succus Rhizoma Dioscoreae,
50 parts of jujube juice, 0.02 part of emulsion stabilizer and 2 parts of white granulated sugar;The emulsion stabilizer includes the raw material group of following parts by weight
Point: 6 parts of sucrose fatty ester, 6 parts of Arabic gum, 2 parts of soya-bean polypeptides, 1.5 parts of astragalus polyose and 0.7 part of phosphate.Further
, a kind of preparation method of Chinese yam jujube composite fermented beverage, comprising the following steps:
(1) prepared by emulsion stabilizer: by weight, weighing each raw material components of emulsion stabilizer;It will be weighed
After Arabic gum, phosphate and water mix to uniformly, water bath processing 10-15min, is then cooled to 65- at 75-80 DEG C
70 DEG C, after adding weighed sucrose fatty ester mixing 5-10min, add soya-bean polypeptides and astragalus polyose stirring
To being uniformly mixed, finally it is lyophilized to get the emulsion stabilizer, it is spare;
(2) prepared by Succus Rhizoma Dioscoreae: after Chinese yam peeling slice, being put into color stabilizer and impregnates 10-20min, pull cleaning out, then
Boiling to yam slice soften, by after softening yam slice and water 1:5 in mass ratio be mixed with beating to obtain Chinese yam pulp, by the Chinese yam pulp
It is placed in 90 DEG C of thermostat water bath and is gelatinized 15-20min, after the Chinese yam pulp after gelatinization is cooled to 60 DEG C, add amylase
Water bath with thermostatic control saccharification 25-30min, finally filtering, centrifuging and taking supernatant, obtain Succus Rhizoma Dioscoreae, spare;
(3) jujube juice prepare: by after stoning jujube and water 1:10 in mass ratio mix boil to boiling, stop heating simultaneously
Keep impregnate 15-20min, be then mixed with beating 2-3 time, refilter 2-3 times, by the filtrate put into a centrifuge carry out from
The heart filters to take supernatant, obtains jujube juice, spare;
(4) raw material weighs: by weight, weighing the above-mentioned emulsion stabilizer prepared, Succus Rhizoma Dioscoreae, jujube juice and white sand
Sugar;
(5) it deploys: weighed Succus Rhizoma Dioscoreae, jujube juice, white granulated sugar and water being mixed to uniformly, allotment juice is obtained;
(6) it ferments: above-mentioned allotment juice being put into after sterilizing 10-15min in 93-95 DEG C of thermostat water bath, be cooled to 40-
43 DEG C, then lactic acid bacteria baking powder is stirred until homogeneous, and finally sealed is put into fermented and cultured 8-10h in 40 DEG C of constant incubator,
Obtain fermented juice;
(7) it filters: after the centrifugation of above-mentioned fermented juice, extracting supernatant to get the Chinese yam jujube composite fermented beverage.
Further, in step (2), the color stabilizer by weight percentage, including salt 1-2% and citric acid 0.2-
0.5%.
Further, in step (3), the revolving speed of the centrifuge is 3500-4000r/min.
Further, in step (7), the sugar content of the Chinese yam jujube composite fermented beverage is 40-45%.
In conclusion by adopting the above-described technical solution, the beneficial effects of the present invention are:
(1) yam and red dates have very high nutritional ingredient as the food of integration of drinking and medicinal herbs, wherein Chinese yam is snowy white juice
The tacky glue of liquid, lightly seasoned pure and fresh, arrange in pairs or groups jujube sweet taste and natural red pigment form brownish red, unique flavor, mouth after fermented
Feel splendid beverage, and the two is arranged in pairs or groups, nourishment for vitality, men and women is suitable for, in addition, ratio of the two in 20-50:30-80 of the present invention
Collocation, so that the total acid content of obtained beverage is 3.78-3.85%, total sugar content 4.7-5.2%, in this sugar acid content
Under, peculiar flavour of the two after everfermentation is remained to greatest extent, aesthetic quality is best, and sensory evaluation scores reach 94 points,
Further, its nutritive value can be improved by carrying out fermentation using lactic acid bacteria, while also have certain medical function, and three is tied
Manufactured beverage health, nutritive value are high altogether.
(2) present invention is using the collocation of sucrose fatty ester, Arabic gum, soya-bean polypeptides, astragalus polyose and phosphate as cream
Change stabilizer, wherein sucrose fatty ester and phosphate collocation have synergistic effect, can effectively improve lipid in jujube and Chinese yam
The hydrophily of substance makes lipid material and remaining raw material especially protein stabilization, evenly dispersed, Arabic gum, soya-bean polypeptides
It arranges in pairs or groups with astragalus polyose and generates synergistic function, not only make the emulsion stabilizer saturating lower than 1.0% in mass concentration
For luminosity (650nm) 97.8% or more, transparency is high, so that beverage product 100% keeps original color, and makes this hair
The surface tension of bright emulsion stabilizer reaches 80.35X10-3N/m is much better than the surface tension of Arabic gum, and its surface tension
It is varied less with the concentration of emulsion stabilizer, so that there is beverage enough buoyancy to guarantee that the uniform of particle hangs in beverage
It is floating, in addition, sucrose fatty ester, Arabic gum, soya-bean polypeptides, astragalus polyose and phosphate collocation, so that emulsion stabilizer
Viscosity is between 0.756-0.762Pas, and under the viscosity, the beverage mouthfeel being prepared is best, and mouth feel score reaches 23 points
(full marks 25 divide) above.
(3) present invention is heat-treated Arabic gum, in the presence of phosphatic so that under the molecular weight of Arabic gum
Drop, then cooling is added sucrose fatty ester and is allowed to re-form finer and close reticular structure with Arabic gum, is eventually adding big
Beans polypeptide and astragalus polyose, are sufficiently adsorbed on and are formed by reticular structure, so that the emulsion stabilizer quality is uniform, steady
It is fixed.
[specific embodiment]
Below in conjunction with specific embodiment, the present invention is further illustrated.
