Abstract

The present invention relates to the technical field of tea preparation, which is applied to the processing of loquat leaves into tea which can be drunk by being directly brewed with boiled water. The present invention has the working procedures that a. fresh leaves whose hair is removed are cleaned, stems and main veins of the leaves are removed, and then the leaves are sliced, and the sliced fresh leaves are put in a mixed solution of bamboo charcoal and water, then taken out and drained; b. the treated fresh leaves are spread in a wood tank to be withered; c. the withered leaves are treated by blowing and heat radiation for cooling, and twisted and sorted by a mesh screen; d. the screened leaves are fermented till the leaf surface turns red and the leaves send out a strong flowery odor; and e. the fermented leaves are dried by gross fire and then dried by strong fire. The finish product is in the form of red strips with brilliant red soup color and strong and palateful taste.

Description

A kind of preparation method of red loquat tea

Affiliated technical field

The present invention relates to the preparing technical field of tea, be applied to loguat leaf is processed into that directly to brew with boiling water be drinkable tea.

Background technology

Compendium of Material Medica and modern medicine study think that all loguat leaf has clearing lung-heat, lowering the adverse-rising QI to resolve phlegm, the effect of cough-relieving.The loguat leaf main chemical is the volatile oil of nerolidol and fanesol, and organic acid, amygdalin and Ve, B family vitamin, tannin, carbohydrate etc.Wherein Feng Fu B17 is the very significant composition of anti-cancer effect, thereby it is believed that loguat leaf has the excellent development prospect.Chinese patent has been announced the technology (application number is 94101639) of a kind of being entitled as " a kind of loquat tea preparation method that can directly brew ", and it has adopted following three road technologies (a) to clean arch and has done; (b) section boiling; (c) the drying packing of weighing.Its deficiency is to have added a spot of food additives aqueous solution in the section digestion process, has destroyed the pure natural property of made finished product thus.

Summary of the invention

The objective of the invention is to overcome above-mentioned the deficiencies in the prior art part, a kind of preparation method of red loquat tea of pure natural is provided.

Purpose of the present invention can reach like this, and a kind of preparation method of red loquat tea is characterized in that it comprises following operation:

(a) bright leaf is handled: bright leaf is removed fine hair, cleans, remove handle and master pulse, cut into slices; At last the fresh leaves that cuts is put into taste removal in the mixed liquor of bamboo charcoal and water, pick up and drain.

(b) wither: the bright leaf tiling that will handle in trogue is opened, 15～25 centimetres of thickness, and temperature remains on 30～39 ℃, turns over once every 1～2 hour, and always the time of withering was controlled at 6～9 hours; When the water content of blade is between 58～65%, the end of withering.The effect of transferring of withering is water evaporates, the food value of leaf deliquescing that makes loguat leaf.

(c) knead sub-sieve: will knead behind the withering leaf air blast radiating and cooling, use then 3～4 holes/time the mesh screen sorting.The compass screen surface leaf is rubbed again, got the sieve bottom leaf.Knead the requirement of leaf rolled twig rate and reach more than 85%, leaf texture's breakage rate becomes 82～85%.

(d) fermentation is outstanding: will sieve the bottom leaf fermentation, it crosses the range request room temperature is 20～26 ℃, and relative humidity is more than 85%, because the biochemistry in the leaf changes, Ye Wenhui rises, but temperature should be controlled at below 30 ℃; When the fragrance of a flower fermentation ends that leaf takes on a red color denseer can be carried out drying.

(e) drying: the dry metapedes fire of first gross fire is dry.The gross fire baking temperature is 110～125 ℃, and the time exceeded 18～25% with water content in 15 minutes.It is dry to carry out foot fire after 30～50 minutes spreading for cooling, and baking temperature is 85～95 ℃, and the time is 15～25 minutes, and leaf water content 4～5% o'clock stops drying, and spreading for cooling 30 minutes is packed to preserve through refining back and got final product.

The present invention has following characteristics: the made finished product strip that takes on a red color; The soup look red is gorgeous, and it is aromatic mellow to distinguish the flavor of.

The specific embodiment

Be further described below the present invention.Pluck 2～8 months viridian loguat leaves, brush away fine hair on the blade, and blade is cleaned with clean water with hairbrush.Use scissors to cut off petiole and master pulse, cut into wide about 1 centimeter length 2-3 centimetre broken side's sheet along each blade of offshoot steering handle.It is that the bamboo charcoal water mixed liquid of 5-8% soaks and removed harmful chemical residue and impure smell in 5-10 minute that broken side's sheet is put into weight ratio after with clean water flushing again, picks up to spread.So finish bright leaf treatment process.Finish following operation then successively:

In trogue, pour the bright leaf of handling into, 15～25 centimetres of tiling thickness, temperature remains between 30～39 ℃, turns over once every 1～2 hour, withers 6～9 hours time, and the water content of blade is withered and is finished between 58～65%.

To wither and knead after transferring leaf air blast radiating and cooling, with 3～4 holes/time mesh screen carry out sorting.The compass screen surface leaf is rubbed again, got the sieve bottom leaf.Knead the requirement of leaf rolled twig rate and reach more than 85%, leaf texture's breakage rate reaches 82～85%.

To sieve bottom leaf and put into fermentation basket and ferment, thickness 8-10 centimetre, room temperature is controlled at 20～26 ℃, and relative humidity is more than 85%.Because the biochemistry in the leaf changes, general leaf temperature will rise, and should constantly stir in the fermentation basket withering leaf this moment and dispel the heat and allow temperature be controlled at below 30 ℃.When the blade face takes on a red color and denseer flowery odour is arranged, can carry out drying.

The dry metapedes fire of elder generation's gross fire is dry.The gross fire baking temperature is 110～125 ℃, and the time exceeded 18～25% with water content in 15 minutes.It is dry to carry out the foot fire after spreading for cooling in 30～50 minutes, and baking temperature is 85～95 ℃, and the time is 15～25 minutes, and leaf water content 4～5% dries by the fire at present, and spreading for cooling packing storage in 30 minutes gets final product.

Claims

1, a kind of preparation method of red loquat tea is characterized in that it comprises following operation:
