Description
Technical field
the invention belongs to tea making technology field, be specifically related to a kind of preparation method of lotus leaf tea.
Background technology
lotus leaf is the leaf of nymphaeaceae plant lotus.In March, 2002 ministry of Health of China defend prison and send out in (2002) No. 51 files, the list that lotus leaf is put into " being food and medicine ".In recent years research finds, lotus leaf is except the chemical composition containing routines such as carbohydrate, lipid, protein, tannin, and be also rich in various bioactivators, wherein the biologically active of flavonoids and alkaloid compound is higher.The pharmacological research of lotus leaf shows, lotus leaf mainly has adjusting blood lipid, fat-reducing, the effect such as anti-oxidant and antibacterial.Flavone compound in lotus leaf mainly contains Quercetin, isoquercitin and lotus glycosides etc.; Alkaloid material mainly contains Nuciferine, N-nornuciferine, O-remove first Nuciferine, reticuline, Ya Meipa alkali, miltanthin etc.At present, to research and the utilization of lotus leaf, be more and more subject to people's attention, in fields such as food and medicines, there is prospect widely.
lotus leaf tea making being brewed and drink, is the simplest way obtaining lotus leaf function composition, play its health-care effect.Traditional artisan craftsmanship processing lotus leaf tea, by lotus leaf slitting, dry, there is outward appearance coarse, not mature taste is dense, fragrance deficiency, not the deficiency such as resistance to bubble.
the very large energy of lotus leaf tea preparation method disclosed in CN102894155A is used for moulding, produces as drink, and moulding seems of such little moment.
the change of main active (flavones or alkaloid) content in the different collecting period lotus leaf of some scholar's research, find that its Fluctuation is the growth along with lotus leaf, general flavone contained by it and Nuciferine content increase gradually, reach peak to the maturity period.Current domestic disclosed patent is raw material mainly with the tender leaf just grown, and wherein activity substance content is low, and health-care effect is unsatisfactory.
Summary of the invention
the technical problem to be solved in the present invention is to provide a kind of lotus leaf tea preparation method.
solve this technical problem and adopt following technical scheme:
this lotus leaf tea preparation method is carried out according to the following steps:
(1) pluck, clean: select soil to be rich in the Lian Tang of selenium, pluck growth cycle 90 ± 5 days, growth and maturity, look green, and blade edge does not present filemot without disease and pest lotus leaf; Lotus leaf tow sides are scrubbed clean, then with flowing tap water one time;
(2) wither: the fresh leaf gathered is made its 3 ~ 12h that naturally withers in aeration-drying place;
(3) slitting: lotus leaf bar withering leaf being cut into 3-6mm*40-80mm specification;
(4) shake blue or green with leave standstill: lotus leaf bar is shaken blue or green 2-5 time, shakes at temperature 20-30 DEG C after green grass or young crops, standing 1-3h under humidity 55%-85% condition at every turn;
(5) complete: complete in roller dryer after shaking green grass or young crops, complete temperature 130-150 DEG C, time 6-7min;
(6) knead: water-removing leaves is put into while hot kneading machine and knead, regulate pressure by runner, gently press 5min, weight 15min hockets, the time of kneading is 55-75min, knead the wax coat of 80%-90% to lotus leaf surface to come off, then by mesh screen sieve dewax matter, leave lotus leaf;
(7) cure: the lotus leaf after kneading is placed in the effect that curer cures to reach drying and Titian, and temperature 70-80 DEG C, time 20-30min, to moisture content < 5%;
(8) pack: the lotus leaf of oven dry is spread out, dries in the air cool to room temperature, packaging of weighing.
the time of withering in described step (2) is 5-10h.
in described step (4), shaking blue or green number of times is 4 times, and shaking the blue or green rear temperature left standstill is 24-26 DEG C, and the humidity left standstill is 65%-75%, time 1.5-2h.
in described step (5), the temperature that completes at 140 DEG C, time 7min.
the invention has the beneficial effects as follows:
the lotus leaf tea tea obtained by this method is aromatic strongly fragrant, and flavour glycol, endures repeated infusions, and active component is high, has excellent health-care efficacy.
Detailed description of the invention
the present invention is described in detail below in conjunction with embodiment:
the applicant passes through the mensuration of flavones, alkaloid and selenium constituent content in each leaf age lotus leaf to the local growth of dragon trip, and find that flavonoids and alkaloidal amount (maturity period) content after growing March is the highest, the content of selenium element is with the continuous enrichment of growth.Consider, select Mature Leaf as tea making raw material.The Mature Leaf food value of leaf is plump, and not mature taste is comparatively large, requires higher to tea-manufacturing technology.
this lotus leaf tea preparation method is carried out as follows:
1) pluck, clean: select soil to be rich in the Lian Tang of selenium, pluck growth cycle 90 days, growth and maturity, look green, and blade edge does not present filemot without disease and pest lotus leaf; Lotus leaf tow sides are scrubbed clean, then with flowing tap water one time;
2) wither: the fresh leaf gathered is made its 5-10h that naturally withers in aeration-drying place;
3) slitting: lotus leaf bar withering leaf being cut into 4mm*60mm specification;
