Abstract
The invention discloses a white tea processing method, and belongs to the technical field of tea processing. The method comprises the following steps: picking fresh tea tree leaves characterized by a bud with a leaf and a bud with two leaves, uniformly spreading the fresh tee tree leaves on a withering tank, disposing at normal temperature to carry out withering, sending the withered leaves to an enzyme deactivating machine, deactivating enzymes, sending the obtained leaves to a microwave enzyme deactivating machine, deactivating enzymes, carrying out tea strip tidying fixing, carrying out drying and fragrance enhancement, screening the obtained tea leaves, and packaging the screened tea leaves to obtain a finished white tea product. Enzyme deactivating treatment of the withered leaves through using the common enzyme deactivating machine and enzyme deactivating treatment of the tea leaves through using microwaves, adopted in the enzyme deactivating step, make beneficial substances, such as tea polyphenol, in white tea, be converted and reserved, so the quality of the white tea is improved.
Description
Technical field
The present invention relates to tea processing technique field, it particularly relates to the processing method of a kind of Ramulus et Folium Mussaendae Pubescentis.
Background technology
Tea is a kind of famous health promoting beverage, and along with the transformation of consumption idea and life style, tea beverage becomes one of Chinese Consumer's favorite drink category.Statistical data shows, tea-drinking consumption market has accounted for the share of about the 20% of whole beverage consumption market.Why tea obtains the favor of consumer, is primarily due to tea not only mouthfeel better, and with health role.Analyzing discovery according to the study, tea has the effect that one, contributes to slow down aging.Two, contribute to suppressing cardiovascular disease.Three, prevention is contributed to and anticancer.Four, contribute to suppressing and opposing virus bacterium.Five, beauty and skin care is contributed to.Six, refreshment is contributed to.Seven, contribute to diuresis to recover from fatigue.Eight, blood fat reducing is contributed to aid digestion.Nine, tooth protection improving eyesight is contributed to.
Ramulus et Folium Mussaendae Pubescentis, element is treasure in tea, with a long history.The topmost feature of Ramulus et Folium Mussaendae Pubescentis is white millifarad, have the aesthetic feeling of " green adornment is in white ", and bud head is stout and strong, and soup yellow skin is bright, the fresh alcohol of flavour, tender even at the bottom of leaf.Tasting after brewing, it is good to eat that fresh alcohol is hidden in taste, moreover it is possible to plays pharmacological action.Traditional Chinese medical science pharmacology proves, Ramulus et Folium Mussaendae Pubescentis is refrigerant, and having brings down a fever drops effect of fire.The processing technology of existing Ramulus et Folium Mussaendae Pubescentis is: wither, dry, pick pick, sieve, beat heap, bakee and vanning.The Ramulus et Folium Mussaendae Pubescentis yield rate of this processes is low, it is impossible to being effectively improved the effective ingredient that finished product Ramulus et Folium Mussaendae Pubescentis leaches, whole technique is relatively long.
Summary of the invention
In view of this, the processing method that it is an object of the invention to provide a kind of Ramulus et Folium Mussaendae Pubescentis, the Ramulus et Folium Mussaendae Pubescentis yield rate to solve the processing of existing method for processing white tea is low, it is impossible to be effectively improved effective ingredient and the deficiency that exists that finished product Ramulus et Folium Mussaendae Pubescentis leaches.
The present invention solves above-mentioned technical problem by the following technical programs:
The processing method of a kind of Ramulus et Folium Mussaendae Pubescentis, comprises the following steps:
(1) pluck: Camellia sinensis, take the fresh leaf of bud one leaf or two leaves and a bud；
(2) wither: fresh leaf of Camelliae sinensis is uniformly spread on withering trough with the thickness of 2cm, places 10-12h at normal temperatures, obtain withering leaf；
(3) completing: sent in green-keeping machine by withering leaf and complete, the temperature that completes is 200-220 DEG C, after the 100-200s that completes, sending in microwave deactivation of enzyme machine after being cooled down by withering leaf, adjustment microwave power is 15-25w/g, and temperature is 100-120 DEG C, fixation time is 80-100s, it is thus achieved that water-removing leaves；
(4) reason bar sizing: sent into by water-removing leaves in carding machine, with the 180-200 per minute rotational speed turned, put into by sizing rod, after 1-2min, takes out sizing rod, it is thus achieved that mature leaf；
(5) Titian is dried: sent into by mature leaf in drying machine, regulate temperature and be 100-110 DEG C, dry after being 20-25% to Measuring Moisture Content of Tea content, Folium Camelliae sinensis is taken out and is cooled to room temperature, then sending in drying machine by Folium Camelliae sinensis, at the temperature of 70-80 DEG C, Titian to its moisture is 5-7%；
(6) screening, packaging: sieved by the Folium Camelliae sinensis after Titian, remove tea dust and non-teas material, then pack, obtain Ramulus et Folium Mussaendae Pubescentis finished product.
The kind of described Camellia sinensis is large leaf Clonal.
The moisture of described withering leaf is 62-64%.
The moisture of described water-removing leaves is 45-50%.
In described step (3), being sent in green-keeping machine by withering leaf and complete, the temperature that completes is 210 DEG C, completing after 150s, send in microwave deactivation of enzyme machine after being cooled down by withering leaf, adjustment microwave power is 20w/g, temperature is 110 DEG C, and fixation time is 90s, it is thus achieved that water-removing leaves.
In described step (5), being sent into by mature leaf in drying machine, regulating temperature is 105 DEG C, dry to Measuring Moisture Content of Tea content be after 22%, being taken out by Folium Camelliae sinensis and be cooled to room temperature, then send in drying machine by Folium Camelliae sinensis, at the temperature of 75 DEG C, Titian to its moisture is 6%.
The beneficial effects of the present invention is: first, the manufacturing process steps of the present invention is simple, technological process length but process cycle is not long.Secondly, the present invention is by de-enzyming process step, adopt and first withering leaf is carried out, with common green-keeping machine, the process that completes, the technique processed that completes is carried out again with microwave, make the nutritional labeling in Folium Camelliae sinensis there occurs bigger micro-variations, enrich the nutrient substance leaching rate of the trophic structure in Folium Camelliae sinensis and raising, by the benefit materials in Ramulus et Folium Mussaendae Pubescentis, namely the material such as tea polyphenols carries out converting and retaining, and then improves tea polyphenols and the like matter (polymerized polyphenolic) content in the Ramulus et Folium Mussaendae Pubescentis prepared.Again, the present invention by controling effectively to each technological parameter in drying Titian step so that the Ramulus et Folium Mussaendae Pubescentis dense alcohol of finished product mouthfeel processed is sweet clearly.
