The method of method for preparing black tea fungus juice beverage by using fermentation
Technical field
The invention belongs to the light industry and food field, relate to the method for utilizing the serial fruit drink of fermented tea fermentation preparation.
Background technology
Fermented tea (Kombucha) is commonly called as Hypon, stomach treasured, is a kind of traditional spontaneous fermentation beverage that originates from China.Fermented tea is to be formed by black tea (or with green tea, oolong tea, bitter leaves tea, jasmine tea etc.), white sugar (or rock sugar, honey) and water brew.Its cultural method is as follows:
(1) cultivation of mother liquor: in boiling water, add earlier black tea, white sugar (rock sugar) a little, the black tea syrup that furnishing is rare, slightly boil sterilization again after, promptly contain in the sterile glass, when being cooled to 35 ℃, add a black tea bacterial classification big again as finger, seal rim of a cup with clean gauze, three, after four days, cup bears green cilium in an end, and liquid level grows mycoderm like the jellyfish, in a few days, the souring of tea liquid, flavor has just been made mother liquor as red bayberry soup.
(2) cultivation of drink liquid: in the jar of sterilizing, add the black tea syrup of boiling, after the cooling, mother liquor is added, cross about a week, promptly be fermented into sour-sweet tea liquid, promptly drinkable.Tea liquid has been drunk, and the starter that stays also can continue as above method cultivation drink liquid, and it is without cease to circulate.The material rate of cultivating fermented tea is a black tea: sugar: water=0.2:5:200.
(3) culture of strains: culture of strains is to carry out on cultivation mother liquor basis.The cenobium that generates in the mother liquor has multilayer, and lower floor is tenderer and bright, should make bacterial classification.Good starter can float over liquid level, the translucent colloid cenobium that is creamy white, and the nutrient solution smell is sour-sweet.Promptly represent contaminatedly if be red green on the cenobium, nutrient solution can not be drunk.
Domestic and international research shows that fermented tea (Kombucha) is actually the probio that three classes are of value to health in recent years, i.e. the syntaxial system of saccharomycete, acetic acid bacteria, lactic acid bacteria composition.In tea, syrup, this three quasi-microorganism interacts, interrelated and complementary fermentation, with raw materials such as sugar, tea through the thalline that is converted into extremely abundant and easier absorption and nutriment (as gluconic acid, glucuronic acid, D-glucaric acid-1,4 lactones, lactic acid, acetic acid, vitamin, polysaccharide, ferment, active peptides etc.), have regulate stomach and intestine, strengthen the brain darling renal function, improve eyesight, various health-care such as bring high blood pressure down, sleep peacefully, be a kind of have utilize the natural microbial fermented beverage that is worth very much.
Present domestic fermented tea also is in family from making from drink or individual workship's production phase, and blank is still located in the marketization.Accelerate exploitation of fermented tea fermented beverage products and production technology optimization research, avoid easily being bacterial contamination from making the self-control production form, purebredly can not provide continuity for oneself, output and quality are limited to be waited not enoughly, fully guarantees product quality and reliable quality safety guarantee.In addition, existing through the prepared single and meta-acid of black-tea fungus drink mouthfeel of tea bacterium production model, assign to source side just by addition portion in culture medium, cheap fruit syrup composite fermentation, can fully keep the original edible and medicinal health function of fermented tea, improve again and optimize product mouthfeel and quality, split rubescent tea probiotic beverage scale Study on Fermentation and promote black-tea fungus drink commercialization meaning very big.
Summary of the invention
The object of the invention provides a kind of method of utilizing fermented tea mixed culture fermentation to prepare the fruit juice beverage.Adopt modern microbial fermentation technology, by optimizing the fermentation condition of fermented tea, form best fermentation manufacturing technique, make good product quality, with short production cycle, the flavor taste color and luster is good, be fit to large-scale production, and meet food security.Overcoming traditional-family's workshop-based spontaneous fermentation quality instability, output can't guarantee and deficiencies such as product mouthfeel difference, the fermentation scale from several liters to tonne all can.By optimizing fruit juice kind and the dosage that is added in the culture medium; improve the product nutritive value and improve mouthfeel, local flavor; promote product quality; prepare differently flavoured fermented tea fruit juice fermentation beverage, for technical foundation is established in industrialized developing, large-scale production and the tea resources comprehensive utilization of fermented tea.
For realizing that the technical scheme that purpose of the present invention adopts is:
1, the preparation of fermented tea mother liquor
At first, select quality good, the south of Fujian Province of taste good natural fermented beverage of fermented tea among the people is female the kind, by screening, separation high-quality fermented tea bacterial strain, preserves standby to make fermented tea mother liquor low temperature after the activation of mixed bacteria form.
2, the raw material proportioning of fermented tea fruit juice
Fermented tea mother liquor 100~300ml
Tealeaves 3~10g
Water 1000ml
Sugar 15~50g
Fruit syrup 100~200ml
3, sweat
Tealeaves is cleaned fast, drained with clear water, make tea with 100 ℃ of bubble system 5-30min, the tea syrup is made in the sugaring dissolving, simultaneously fresh fruit is cleaned, peeling or stripping and slicing, 135 ℃ of steam surface quick sterilization 1min, to squeeze the juice after squeezing the juice adds in the tea syrup, and mixing inserts the fermented tea mother liquor that has activated, adopt microorganism fermentation tank (charge reaches more than 90% of tank body volume) to enter the fermentation stage fermentation, fermentation temperature is 25 ℃-35 ℃.
Fermentation stage is divided into the ventilation in early stage and stirs fermentation and two different fermentations stages of later stage standing for fermentation: the stirring fermentation time that ventilates early stage is 18~30 hours, the standing for fermentation time in later stage is 60~72 hours, the stirring fermentation stage that ventilates early stage keeps stirring all the time and ventilation is cultivated, speed of agitator is 130~200r/min, per minute (min) throughput (V
Gas) be the volume (V of total zymotic fluid
Always) 25~50 ﹪.After the stirring fermentation stage that ventilates early stage finishes, change the later stage standing for fermentation over to until putting jar.After standing for fermentation was cultivated 50h, liquid level began to form the mycoderm of layer of transparent, and along with cultivating continuity, mycoderm is thickeied gradually becomes the block film of plump white size, put jar to leach zymotic fluid and be the fermented tea fruit drink.
And different, it is light yellow that majority is with fruit juice kind difference for the color of fermented tea fruit drink, and sweet mouthfeel is tasty and refreshing, the fruit aroma that tool is strong.After measured, residual sugar content 2.0~3.0g/100ml in the fermented tea fruit drink, pH is 3.0~3.5, ethanol content is less than 1%.
Tealeaves of the present invention is meant black tea, green tea, jasmine tea or oolong tea;
Described sugar is sucrose, glucose, fructose and brown sugar;
Fruit of the present invention adopts grape, orange, lichee, apple, pear, shaddock, water chestnut or fragrant plant happy.
