Description
Technical field
The present invention relates to tea making field, particularly a kind of manufacture craft of lotus nut black tea.
Background technology
Black tea, with the new tea bud-leaf of suitable for making this product for raw material, through the tune that withers, knead, ferment, it is dry etc. that typical process process is refining forms.Because its dry dark brown pool and the millet paste that brews are homophony with redness, therefore named black tea.Black tea there occurs the chemical reaction centered by Tea Polyphenols enzymatic oxidation in process, and the chemical composition change in fresh leaf is comparatively large, and Tea Polyphenols reduces more than 90%, creates the composition that theaflavin, thearubigin etc. are new.Aroma substance, from the kind more than 50 fresh leaf, increases to kind more than 300, a part of caffeine.Catechin becomes the complex compound of flavour deliciousness with theaflavin complexing, thus defines the qualitative characteristics of black tea, red soup, red autumnal leaves and fragrant and sweet taste alcohol.
Lotus nut, its taste is poor, containing the Flavonoid substances such as liensinine, isoliensinine.Having clears away heart-fire reduces phlegm and internal heat, the effect of controlling nocturnal emission with astringent drugs hemostasis and fabulous step-down degrease.But there is the report about the nutritional labeling of lotus nut being applied to black tea also few at present.
Summary of the invention
The invention provides a kind of manufacture craft of lotus nut black tea, effectively drawn the nutritional labeling of lotus nut in black tea, lotus nut black tea taste is sweet salubrious, and having clears away heart-fire reduces phlegm and internal heat, the effect of controlling nocturnal emission with astringent drugs hemostasis and fabulous step-down degrease.。
For achieving the above object, technical scheme of the present invention is:
A manufacture craft for lotus nut black tea, comprises the following steps:
Step 1: leaf picking;
Step 2: wither, spreads in withering trough by fresh leaf, is placed in indoor shady and cool ventilation place airing, and airing thickness is 11cm ~ 13cm, and initial temperature is 36 ~ 38 DEG C, maintain 2 ~ 3h, after temperature is adjusted to 25 ~ 28 DEG C, maintain 3 ~ 5h;

Second time is kneaded, and adopts kneading machine first not pressurize and kneads 10 ~ 15min, then knead 40 ~ 45min under carrying out pressurized conditions, sieve, deblock;
Step 4: fermentation, ferment in fermenting cellar, temperature is 25 ~ 28 DEG C, humidity be 95% and more than, fermentation time is 4 ~ 6h;
Step 5: microwave drying, adopt micro-wave oven tealeaves is dried, dry to tealeaves moisture content be 30 ~ 40%;
Step 6: the extraction of lotus nut extract, technique is: dry lotus nut adopts 45 ~ 50 DEG C of pure water sealing immersion 30 ~ 40min, pure water consumption is every kilogram of dry lotus nut 1 ~ 2L, lotus nut and soak thereof are added beater making beating, adopt ultrasonic wave air exercise slurries to extract, Extracting temperature is 45 ~ 50 DEG C, and extraction time is 30 ~ 40min, adopt filter paper to carry out suction filtration and obtain extract, use in extract 24h;
Step 7: once spray, the tealeaves after step 5 being dried shakeouts, and leaf-spreading thickness is less than 5cm, and keep temperature 35 ~ 40 DEG C, re-use lotus nut extract and evenly spray it in ullrasonic spraying mode, spray flux is every kilogram of tealeaves 50 ~ 70mL lotus nut extract;
Step 8: carry out room temperature airing to the tealeaves after spray, the airing time is 30 ~ 50min;
Step 9: dry, adopt drying machine drying, baking temperature is 45 ~ 50 DEG C, dry to tealeaves moisture content be 25 ~ 35%;
Step 10: secondary spraying, shakeout by the tealeaves after drying, leaf-spreading thickness is less than 5cm, keeps temperature 35 ~ 40 DEG C, and use lotus nut extract to spray it in ullrasonic spraying mode, spray flux is every kilogram of tealeaves 30 ~ 50mL;
Step 11: dry, adopt drying machine drying, baking temperature is 45 ~ 50 DEG C, dry to tealeaves moisture content be 15 ~ 18%;
Step 12: carry out room temperature airing to the tealeaves after drying, the airing time is 1 ~ 1.5h;
Step 13: dry, adopt drying machine drying, baking temperature is 45 ~ 50 DEG C, and drying to tealeaves moisture content is less than 6%, and hand is pinched tea stalk and become end.
Further, micro-wave oven frequency used in described step 5 be 2000MHz and more than, power be 10kW and more than.
Further, described first time knead in pressurization knead, adopt the mode of heavy-light reciprocation cycle, gently the time of kneading is 30 ~ 60s, and pressure is 25kg/cm
