Abstract
The invention relates to a process for processing instant tea powder, in particular to the process special for processing instant tea powder of purple tea. The process is completed by cutting, extracting, filtering and drying the tea serving as raw materials, and is characterized in that the cut granularity of the tea is 3 to 6mm, the extracting process is to add extracting solution of which the weight is 10 to 15 times that of the tea into the cut tea, and perform the extraction with stirring at the temperature of 18 to 28 DEG C for 2 to 3h, and the drying process is to perform spray drying at a feeding speed of 1.5 to 4L/h at the inlet temperature of 100 to 110 DEG C and the outlet temperature of 55 to 60 DEG C. The process is simple and convenient, stable and low in production cost, the active content of the tea can be effectively extracted, the tea product has high polyphenol content, and the soup color and aroma of the original tea can be effectively kept after the tea is steeped.
Description
Technical field
The present invention relates to a kind of process for processing instant tea powder, be exclusively used in especially the process for processing instant tea powder of purple beautiful tea.
Background technology
Distinctive convenient, the quick consumption pattern of instant tea powder becomes the consumption pattern of present main flow gradually, contains more and more extremely liking of consumer of health care, healthy drink.Tealeaves has long history as the traditional beverage of China, but because it drinks inconvenience, not quick, and so that new tea-drinking product are constantly explored and developed in each producer, cater to consumer demand.Now the technology of domestic existing production instant tea powder, in these technology, the instant tea powder manufacture method mostly is uses the hot water lixiviate, with tea through filter cloth or filter screen, filter plant isolated by filtration, then through Vacuum Concentration, recycling spray-drying or freeze drying.The losing issue that easily causes nutrient is carried in shortcoming and hot dipping that but there are product fragrance in these processing methods, brew the soup aberration.The patent of notification number CN101164424 discloses a kind of preparation method of instant tea powder: adopt the different temperatures section to extract fragrance component and the taste substance of different boiling, after filtration, enzymolysis, the technique such as concentrated, dry are made instant tea powder, but the method technique is wordy, stage extraction has lengthened the production cycle, and enzymolysis can be introduced corresponding protein accessory substance, deal with improperly and may cause the phenomenon that brews rear muddiness, the method is compared traditional extraction cost and is had high input.Notification number CN1101506A discloses a kind of Novel tea inspissated juice beverage, the method be with tea extract behind initial filter, Vacuum Concentration, obtain a kind of tea juice concentrating through ultrafiltration again, but because the method adopts Vacuum Concentration fully, may cause the loss of volatile substances, and cause tealeaves fragrance also poor.Notification number CN1299588C discloses a kind of instant tea powder and processing technology thereof, the instant tea powder that the method utilizes the techniques such as ultrasonic extraction,, spray-drying concentrated through coarse filtration, ultrafiltration membrance filter, film to make, but may easily cause milipore filter to stop up in the actual production process, lengthen the production cycle, secondly the concentrated input that increases cost of ultrafiltration and film.
Summary of the invention
For the deficiencies in the prior art part, it is easy that technical problem to be solved by this invention provides a kind of processing, and process stabilizing, production cost are lower, can effectively extract the active ingredient in the tealeaves, the product polyphenol content is high, can effectively keep soup look and fragrance after former tealeaves brews.
Solving the scheme that technical problem of the present invention adopts is: the beautiful tea of purple is pulverized, finished through low temperature extraction, filtration, spray-drying step, and described pulverizing process be that tealeaves is shredded material to 3～6 mm granularities; Described abstraction process is, adds the aqueous solution liquid of 10～15 times of weight in above-mentioned crushing rear material, stirs at 18～28 ℃ and extracts 2～3h; Described drying process is, is that 100～110 ℃, outlet temperature are under 55～60 ℃ the condition in inlet temperature, carries out spray-drying with charging 1.5～4 L per hour, carries out the Powdered finished product of quantitative package after the drying.
Tealeaves of the present invention adopt purple beautiful tea (State Administration of Forestry's Forestry New Varieties of Plants, kind power number: 20050031, applicant: Tea Inst., Yunnan Academy of Agricultural Science).
Technique of the present invention has following characteristics: (1) the present invention adopts low temperature (18～28 ℃) to stir and extracts, and can effectively reduce the volatilization of oxidizing brown stain and the low boiling aromatic substance of tea juice; (2) process of whole procedure extraction and powder process is all carried out under normal temperature or lower temperature, can not destroy the active ingredient in the extract; (3) whole preparation process succinct, make things convenient for equipment investment little; (4) product appearance is good, can keep the distinctive lavender of purple beautiful tea Powdered; (5) can effectively keep soup look and flowers and fruits characteristic aroma after former tealeaves brews after gained tea powder brews; (6) remedied purple beautiful instant tea powder vacancy.
Processing technology of the present invention has been avoided traditional loose tea and cake tea physical form processing mode, finished product with powdery bag packaged configuration, adopt warm water to brew instant, polyphenol content is higher, embodied brew convenient, the characteristics of easy to carry, storage safe stay in grade, and then enriched the product category of purple beautiful tea.
The specific embodiment
Embodiment 1:Choose purple beautiful tea 10 KG that prepared, utilize mechanical shredding type with the material of tealeaves chopping to 3 mm granularities, the soft water that adds again 15 times of quality, 20 ℃ of lower stirring and leaching 2 hours, after the essence filter, inlet temperature is that 100 ℃, outlet temperature are under 55 ℃ the condition, carries out spray-drying and the Powdered finished product of lavender that obtains with charging 2 L per hour.Patent of the present invention has solved not only that purple beautiful tea brews conveniently, the characteristics of easy to carry, storage safe stay in grade, and has further enriched the product category of purple beautiful tea.
Embodiment 2:Choose purple beautiful tea 10 KG that prepared, utilize mechanical shredding type with the material of tealeaves chopping to 4 mm granularities, the alcohols solvent, the soft water mixed liquor that add again 13 times of quality, 22 ℃ of lower stirring and leaching 150 minutes, after the essence filter, inlet temperature is that 105 ℃, outlet temperature are under 57 ℃ the condition, carries out spray-drying and the Powdered finished product of lavender that obtains with charging 3 L per hour.Patent of the present invention has solved not only that purple beautiful tea brews conveniently, the characteristics of easy to carry, storage safe stay in grade, and has further enriched the product category of purple beautiful tea.
Embodiment 3:Choose purple beautiful tea 10 KG that prepared, utilize mechanical shredding type with the material of tealeaves chopping to 6 mm granularities, the alcohols solvent, soft water, the inorganic acid mixed liquor that add again 15 times of quality, 25 ℃ of lower stirring and leaching 3 hours, after the essence filter, inlet temperature is that 110 ℃, outlet temperature are under 60 ℃ the condition, carries out spray-drying and the Powdered finished product of lavender that obtains with charging 4 L per hour.Patent of the present invention has solved not only that purple beautiful tea brews conveniently, the characteristics of easy to carry, storage safe stay in grade, and has further enriched the product category of purple beautiful tea.
