Abstract
The present invention is a kind of production technology of caffein, and it utilizes ethanol water to make leaching liquor, or adds ethanol water in concentration process, has improved the quality of caffein effectively, makes that the color of the caffein produced by the present invention is all same with former teas.Technology of the present invention can be widely used in green tea, black tea and various Special tea.Technical process of the present invention is simple, safety non-toxic, and the finished product deliquescence is slower than existing product.
Description
The present invention relates to the production technology of daily living article, belong to the production technology of Tea Processing technology, particularly a kind of caffein.
Caffein claims instant tea again, and extraction tea is a kind of particle type powdered solid (crystal) that extracts from tealeaves, and it is promptly drinkable to wash by water, and it has dissolving soon, brew and do not stay recrement, and health, easy to carry, stablize advantages such as not perishable, receive an acclaim day by day.
Abroad, the manufacturing process of its caffein can be divided two classes substantially: a class such as U.S. Pat A, 552,776 " black tea concentrates " and U.S. Pat 4,552, concentrate again after the water of the disclosed employing higher temperature of 769 " the black tea extracts of cold water solubles " extracts black tea and make instant tea, this method easily causes the destroyed and volatilization of some effective ingredients in the tealeaves because of the temperature height, influence former tea local flavor, an another kind of as day disclosure special permission communique 61-15651 discloses the tealeaves leaching process is divided into low temperature and heats two steps, this method can be avoided owing to high temperature destroys effective ingredient in the former tea, but its operation is numerous and diverse, the speed made is held tea and is only applicable to 80 ℃ water-soluble separating and drinks, for this reason, people have adopted the method that low temperature repeatedly leaches to extract for the effective ingredient that keeps former tea, for example Chinese patent application 88105853.X " a kind of manufacture method of instant tea " adopts 5-50 ℃ water repeatedly to leach, and instantaneously sterilising, vacuum decompression concentrates, and methods such as frozen drying are handled.Several type organics that also proposed in the Chinese patent application number " 90109885.X " in addition in a kind of effective ingredient that tealeaves is contained are separated, subsequently to after isolated each type organic method of taking respectively to adapt with it handles, again it is mixed and made into the production technology of instant tea, the common defective of these methods is to use water as leaching liquor, when concentrating, need the higher time of temperature longer, thereby destroy the effective ingredient of caffein, influence the quality of caffein, and the organic substance that adopts healthy influential to human body.
Purpose of the present invention is exactly the production technology of a kind of caffein of providing in order to address the above problem.
The technical solution of caffein production technology of the present invention is as follows:
A kind of production technology of caffein, it includes lixiviate, concentrate, operations such as drying, it is characterized in that: in the lixiviate operation, adopting the ethanol water of concentration of alcohol≤90% is the caffein leaching liquor, at first, ethanol water is added in the raw material tea at normal temperatures, with the submergence of raw material tea through after 5-8 hour, win time extractive juice of filtration, in the raw material tea of the extracted first time, add again again ethanol water with the submergence of raw material tea through after 5-8 hour, filter extractive juice for the second time, twice extractive juice mixing of gained in the lixiviate operation concentrated, the temperature of enrichment process is controlled at 60 ℃-80 ℃, and the concentrate of enrichment process gained enters drying process, gets product after the drying.
Caffein production technology of the present invention also can be by after finishing in the lixiviate operation, adding ethanol water in the extractive juice mixed liquor finishes, operations such as it still includes lixiviate, concentrate, drying, at first, in the lixiviate operation, the water that utilizes 80 ℃ is as the caffein leaching liquor, the extractive juice that lixiviate is several times gone out mixes, concentrate after it is characterized in that in the extractive juice mixed liquor, adding the ethanol water of ethanol content≤90%, the temperature of enrichment process is controlled at 60 ℃-80 ℃, the concentrated drying process that enters of enrichment process gained gets product after the drying.
The invention has the advantages that and adopted ethanol water as the caffein leaching liquor with in enrichment process, add ethanol water, make the production process of caffein change between greatly, it is fast that the extractive juice mixed liquor concentrates speed, temperature is low, the effective ingredient of tealeaves is kept to greatest extent, utilize the caffein of explained hereafter green tea of the present invention, black tea, its taste and former teas are together, finished color and natural tea form and aspect with, entire production process safety, nontoxic, the damp aquatic foods of finished product are slow.
The present invention is further described as follows below by embodiment:
Embodiment 1: instant green tea: the ethanol water of selecting ethanol content 70% for use is that leaching liquor (1) at first joins in 1 kilogram of green tea (or tealeaves is not) with the 5L ethanol water, soaks under the room temperature after 6 hours, filters and obtains primary extractive juice.(2) join in the former tea of extracted with the ethanol water of 5L again, get extractive juice for the second time by (1) step lixiviate.(3) extractive juice in (1) and (2) step is mixed to such an extent that contain the mixed liquor of caffein about 10%.(4) mixed liquor in (2) step is concentrated by the vacuum decompression concentration pan, thickening temperature is controlled at 70 ℃, make leaching liquor owing to adopt ethanol water, its boiling point is low, and it is faster than water to concentrate speed fortune, makes that the effective ingredient of former tea is kept to greatest extent, concentrate after concentrating, the content of caffein is 30-50%, and ethanolic solution obtains reclaiming in this process, and its rate of recovery can reach 90%.(5) (4) step gained concentrate is carried out drying with vacuum freeze-drying method, perhaps carry out drying with the dry box spray drying process of vacuum canopy formula, dried caffein is smashed processing through generality, after pack productive rate about 30%.During use, only need to use the warm water Instant Drinks, it is fast to have dissolving, brew and do not stay recrement, stablize advantages such as not perishable, color is all same with former teas, for the step 2 that improves in the productive rate present embodiment can repeat 1-2 time, in order to reduce the consumption of ethanol, can utilize a plurality of extractors to carry out the lixiviate of consecutive formula.
Embodiment 2 green tea caffeins, its basic production technical process is identical with embodiment 1.Just leaching liquor wherein also can utilize 80 ℃ of water as leaching liquor technology lixiviate routinely, in the mixed liquor of lixiviate gained, adding ethanol content and be behind 70% the ethanol water by embodiment 1(4) (5) step handles, present embodiment to the greatest extent part is not identical with embodiment 1, can reduce the loss of the effective ingredient of caffein in concentration process like this.
Utilize technology of the present invention can produce green tea, black tea and other Special tea.
