Njengamanje, impushana ye-matcha ihlanganisa ikakhulukazi impushana yetiye eluhlaza kanye nempushana yetiye emnyama. Izindlela zabo zokucubungula zichazwe kafushane kanje.

1. Umgomo wokucubungula we-green tea powder

Impushana yetiye elihlaza icutshungulwa emaqabunga etiye amasha ngokusebenzisa amasu afana nokusabalalisa, ukwelashwa kokuvikela okuluhlaza, ukubuna, ukugoqa, ukuphelelwa amanzi emzimbeni nokomisa, kanye nokugaya i-ultrafine. Isihluthulelo sobuchwepheshe bayo bokucubungula silele ekutheni ungalithuthukisa kanjani izinga lokugcinwa kwe-chlorophyll futhi wenze izinhlayiya ze-ultrafine. Ngesikhathi sokucutshungulwa, amasu akhethekile okuvikela okuluhlaza asetshenziswa kuqala lapho amaqabunga amasha asatshalaliswa, kulandelwa ukubuna kwezinga lokushisa eliphezulu ukuze kucekelwe phansi umsebenzi we-polyphenol oxidase nokugcina izinhlanganisela ze-polyphenol, okwenza ukunambitheka kwetiye eliluhlaza. Ekugcineni, izinhlayiya ze-ultrafine zenziwa kusetshenziswa ubuchwepheshe bokugaya be-ultrafine.

Izici zekhwalithi ze-green tea powder: ukubukeka okuntekenteke nokufana, umbala oluhlaza ogqamile, iphunga elimnandi, ukunambitheka okucebile nokuthambile, nombala wesobho oluhlaza. Impushana yetiye eluhlaza kakhulu ifana ngokunambitheka nephunga netiye elivamile eliluhlaza, kodwa umbala walo uluhlaza ikakhulukazi futhi izinhlayiya zinhle kakhulu. Ngakho-ke, umgomo wokucubungula we-ultrafine green tea powder ubonakala ngokuyinhloko ezicini ezimbili: indlela yokusebenzisa ubuchwepheshe bokuvikela okuluhlaza ukuvimbela ukulimala kwe-chlorophyll, ukwakha umbala oluhlaza, nokusebenzisa ubuchwepheshe bokuchoboza be-ultrafine ukwakha izinhlayiya ze-ultrafine.

① Ukwakheka kombala oluhlaza oyisimaragidu: Umbala oluhlaza ogqamile wetiye elomile nombala oluhlaza okotshani oyisimaragidu wesobho letiye yizici ezibalulekile zekhwalithi yempushana yetiye eluhlaza. Umbala wayo ikakhulukazi uthonywa ukwakheka, okuqukethwe, kanye nenani lezinto ezinemibala equkethwe emaqabunga etiye amasha ngokwawo kanye nalawo akhiwe ngesikhathi sokucubungula. Ngesikhathi sokucutshungulwa kwetiye eliluhlaza, ngenxa yokucekelwa phansi okukhulu kwe-chlorophyll a kanye ne-chlorophyll b engaphansi, umbala uyashintsha kancane kancane usuka koluhlaza uye ophuzi njengoba ukucubungula kuqhubeka; Ngesikhathi sokucutshungulwa, ama-athomu e-magnesium esakhiweni samangqamuzana e-chlorophyll athathelwa indawo kalula ama-athomu e-hydrogen ngenxa yethonya lomswakama nokushisa, okuholela ku-oxidation ye-magnesium ye-chlorophyll kanye nokushintsha kombala kusuka kokuluhlaza okukhanyayo kuya kokuluhlaza okumnyama. Ngakho-ke, ukuze kucutshungulwe i-ultrafine green tea powder enezinga eliphezulu lokugcinwa kwe-chlorophyll, inhlanganisela ephumelelayo yokwelashwa kokuvikela okuluhlaza kanye nobuchwepheshe bokucubungula okwenziwe kahle kufanele kwamukelwe. Ngasikhathi sinye, izingadi zetiye zingasetshenziselwa ukwelashwa kwe-shading futhi izinto ezintsha zamaqabunga ezinhlobonhlobo zezihlahla zetiye ze-chlorophyll zingakhethwa ukuze zikhiqize.

② Ukwakhiwa kwezinhlayiya ze-ultrafine: Izinhlayiya ezinhle zingesinye isici esibalulekile sekhwalithi ye-green tea powder. Ngemva kokucubungula amaqabunga amasha abe yimikhiqizo eseqediwe kancane, imicu yezitshalo yetiye elomisiwe iyaphuka futhi inyama yamaqabunga igaywe ukuze yakhe izinhlayiya ngamandla angaphandle. Ngenxa yokuthi itiye liyisitshalo esisekelwe esitshalweni esinokuqukethwe okuphezulu kwe-cellulose, kufanele kuqashelwe:

a. Itiye kumele lomiswe. Ngokuvamile, itiye elomile linomswakama ongaphansi kuka-5%.

b. Khetha indlela efanele yokusetshenziswa kwamandla angaphandle. Izinga le-pulverization yetiye liyahlukahluka kuye ngamandla angaphandle asebenza kulo. Njengamanje, izindlela eziyinhloko ezisetshenziswayo ukugaya amasondo, ukugaywa kwebhola, ukupotshozwa kokugeleza komoya, ukupotshozwa okuqandisiwe, nokushaya ngenduku okuqondile. Ngokukhiqiza imiphumela engokomzimba efana ne-shear, ukungqubuzana, kanye nokudlidliza kwe-high-frequency emaqabunga etiye, imicu yesitshalo setiye namaseli e-mesophyll ayahlukaniswa ukuze kuzuzwe ukuputshuzwa kwe-ultrafine. Ucwaningo selukhombisile ukuthi ukusetshenziswa kwesando senduku eqondileukuchotshozwa kwetiyeifaneleka kakhulu.

c. Ukulawula izinga lokushisa letiye lezinto ezibonakalayo: Enqubweni yokugaya i-ultrafine, njengoba amaqabunga etiye echotshozwa, izinga lokushisa lempahla liyaqhubeka nokukhuphuka, futhi umbala uzophenduka ophuzi. Ngakho-ke, imishini yokuchoboza kufanele ifakwe idivayisi yokupholisa ukulawula izinga lokushisa lempahla. Ubumnene nokufana kwezinto ezingavuthiwe zamaqabunga ziyisisekelo sekhwalithi ye-ultrafine green tea powder. Izinto zokusetshenziswa zokucubungula impushana yetiye eliluhlaza ngokuvamile zilungele amaqabunga amasha etiye lasentwasahlobo nelasekwindla. Ngokocwaningo lwe-Tea Research Institute ye-Chinese Academy of Agricultural Sciences, okuqukethwe kwe-chlorophyll emaqabunga amasha asetshenziselwa ukucubungula impushana yetiye eluhlaza kufanele ibe ngaphezu kuka-0.6%. Kodwa-ke, ehlobo, amaqabunga etiye amasha anokuqukethwe kwe-chlorophyll ephansi kanye nokunambitheka okubabayo okuqinile, okuwenza angakufanelekeli ukucubungula i-ultrafine yetiye powder eluhlaza.

Izinyathelo zokucubungula impushana yetiye: amaqabunga amasha asakazwa ukuze athole ukwelashwa kokuvikela okuluhlaza →ukubuna komusi(noma ukubuna kwesigubhu), iqabunga elilodwa lichotshozwa libe yizicucu (kusetshenziswa ukubuna kwesigubhu, le nqubo ayidingeki) →ukuginqika→ ukuhlolwa kwebhulokhi → ukuphelelwa amanzi emzimbeni nokomisa → ukugaya nge-ultrafine → ukupakishwa komkhiqizo oqediwe.
