A halin yanzu, matcha foda ya ƙunshi koren shayi da kuma baƙar fata. An yi bayanin dabarun sarrafa su a takaice kamar haka.

1. Processing manufa na kore shayi foda

Ana sarrafa foda koren shayi daga sabon ganyen shayi ta hanyar dabaru kamar yadawa, maganin kariyar kore, bushewa, birgima, bushewa da bushewa, da niƙa ultrafine. Makullin fasahar sarrafa ta ya ta'allaka ne kan yadda ake haɓaka ƙimar riƙewar chlorophyll da samar da ƙwayoyin ultrafine. A lokacin sarrafawa, ana fara amfani da dabarun kariya na musamman koren lokacin da sabbin ganye suka bazu, sannan kuma zafi mai zafi ya bushe don lalata ayyukan polyphenol oxidase da riƙe mahaɗan polyphenol, suna samar da ɗanɗanon shayi. A ƙarshe, ultrafine barbashi ana yin su ta amfani da fasahar niƙa ultrafine.

Halayen ingancin kore shayi foda: m da uniform bayyanar, haske koren launi, babban kamshi, arziki da m dandano, da kuma koren miya launi. Ultra fine green tea powder yayi kama da dandano da kamshi zuwa koren shayi na yau da kullun, amma launin sa musamman kore ne kuma barbashi suna da kyau musamman. Don haka, tsarin sarrafa foda na ultrafine koren shayi yana nunawa a fannoni biyu: yadda ake amfani da fasahar kariya ta kore don hana lalacewar chlorophyll, samar da launi kore, da amfani da fasahar murkushe ultrafine don samar da barbashi na ultrafine.

① Samuwar Emerald koren launi: Launin Emerald mai haske na busassun shayi da kuma Emerald koren miya na shayi sune mahimman halaye na ingancin ultrafine kore shayi foda. Launin sa ya fi tasiri ta hanyar abun da ke ciki, abun ciki, da rabon abubuwa masu launi da ke cikin sabon shayin ganyen kansu da waɗanda aka kafa yayin sarrafawa. A lokacin sarrafa koren shayi, saboda gagarumin lalata chlorophyll a da ƙarancin chlorophyll b, launi a hankali yana canzawa daga kore zuwa rawaya yayin da aikin ke ci gaba; A lokacin sarrafawa, atom ɗin magnesium a cikin tsarin kwayoyin halitta na chlorophyll ana samun sauƙin maye gurbinsu da atom ɗin hydrogen saboda tasirin zafi da zafi, wanda ke haifar da iskar magnesium na chlorophyll da canjin launi daga kore mai haske zuwa koren duhu. Sabili da haka, don aiwatar da ultrafine koren shayi foda tare da ƙimar riƙewar chlorophyll, ingantaccen hadewar maganin kariyar kore da ingantaccen fasahar sarrafawa dole ne a karɓi. A lokaci guda, ana iya amfani da lambunan shayi don maganin shading kuma ana iya zaɓar sabbin kayan ganye na nau'ikan itacen shayi na chlorophyll don samarwa.

② Samuwar ultrafine barbashi: Fine barbashi ne wani muhimmin sifa na ingancin kore shayi foda. Bayan sarrafa ganyen ganye zuwa kayan da ba a gama ba, sai a karye filayen busasshen shayin kuma ana niƙa naman ganyen don su zama ɓangarorin da ƙarfi daga waje. Saboda gaskiyar cewa shayi abu ne na tushen shuka tare da babban abun ciki na cellulose, ya kamata a kula da:

a. Dole ne a bushe shayi. Gabaɗaya, busassun shayi yana da ɗanɗano da ke ƙasa da 5%.

b. Zaɓi hanyar da ta dace na aikace-aikacen ƙarfin waje. Matsayin ɓarkewar shayi ya bambanta dangane da ƙarfin waje da ke aiki da shi. A halin yanzu, manyan hanyoyin da ake amfani da su sune niƙan ƙafafu, niƙa ƙwallon ƙafa, ɓarkewar iska, daskararre, da bugun sanda kai tsaye. Ta hanyar haifar da tasirin jiki irin su shear, gogayya, da girgiza mai-girma akan ganyen shayi, filayen shukar shayin da ƙwayoyin mesophyll suna yayyage don cimma buguwar ultrafine. Bincike ya nuna cewa amfani da guduma madaidaiciya donfasa shayiya fi dacewa.

c. Sarrafa yawan zafin jiki na kayan shayi: A cikin tsarin niƙa na ultrafine, yayin da aka murƙushe ganyen shayi, zafin kayan yana ci gaba da tashi, kuma launi zai zama rawaya. Sabili da haka, kayan aikin murkushe dole ne a sanye su da na'urar sanyaya don sarrafa yanayin zafin kayan. A taushi da kuma uniformity na sabo ne ganye albarkatun kasa ne abu tushen ga ingancin ultrafine koren shayi foda. Abubuwan da ake amfani da su don sarrafa koren shayin foda sun dace da ganyen shayi na bazara da kaka. Bisa binciken da cibiyar binciken shayi na kwalejin kimiyyar aikin gona ta kasar Sin ta gudanar, ya nuna cewa sinadarin chlorophyll a cikin sabobin ganyen da ake amfani da shi wajen sarrafa koren shayi ya kamata ya wuce kashi 0.6%. Koyaya, a lokacin rani, sabbin ganyen shayi suna da ƙarancin abun ciki na chlorophyll da ɗanɗano mai ɗaci, yana sa su rashin dacewa da sarrafa ultrafine koren shayi foda.

Matakan sarrafa foda koren shayi: ana yada ganyen ganye don maganin kariyar kore →tururi bushewa(ko bushewar ganga), ana niƙa ganye guda ɗaya (ana amfani da bushewar ganga, ba a buƙatar wannan tsari) →mirgina→ toshe nunawa → bushewa da bushewa → ultrafine nika → kammala marufi.
