Khofi wopanda caffeine, kapena "decaf," wozikika molimba ngati chinthu chofunidwa kwambiri mubizinesi yapadera ya khofi.
Ngakhale mitundu yoyambirira ya khofi ya decaf idalephera kukopa chidwi cha makasitomala, zatsopano zikuwonetsa kuti msika wapadziko lonse wa khofi wa decaf ukuyembekezeka kufika $2.8 biliyoni pofika 2027.
Kukula kumeneku kungakhale chifukwa cha chitukuko cha sayansi chomwe chapangitsa kuti anthu azigwiritsa ntchito njira zotetezeka komanso zochepetsera caffeine.Kukonza nzimbe ethyl acetate (EA), komwe nthawi zambiri kumadziwika kuti nzimbe decaf, ndi njira ya Swiss Water decaffeination ndi zitsanzo ziwiri.
Kukonza nzimbe, komwe kumadziwikanso kuti Natural Decaffeination, ndi njira yachilengedwe, yaukhondo, komanso yosunga zachilengedwe yopangira khofi wopanda khofi.Zotsatira zake, khofi wa nzimbe wa decaf akutchuka kwambiri m'makampani.
Kusintha kwa Coffeinated Coffee
Kumayambiriro kwa 1905, benzene idagwiritsidwa ntchito pochotsa caffeine kuchotsa khofi kuchokera ku nyemba za khofi zomwe zidaviikidwa kale.
Komano, kukhudzana kwa nthawi yayitali ndi benzene wochuluka, kumbali ina, kwasonyezedwa kukhala kovulaza thanzi la munthu.Ambiri omwe amamwa khofi mwachibadwa anali ndi nkhawa ndi izi.
Njira ina yoyambirira inali kugwiritsa ntchito methylene chloride monga chosungunulira kuti asungunuke ndi kuchotsa caffeine kuchokera ku nyemba zobiriwira.
Kugwiritsiridwa ntchito kwa zosungunulira kosalekeza kunadetsa nkhaŵa anthu amene amamwa khofi osamala thanzi lawo.Komabe, mu 1985, Food and Drug Administration (FDA) idavomereza zosungunulira izi, ponena kuti mwayi wokhala ndi nkhawa zathanzi kuchokera ku methylene chloride unali wochepa.
Njira zopangira mankhwalazi nthawi yomweyo zidathandizira "kufa pamaso pa decaf" moniker yomwe yatsagana ndi zopereka kwa zaka zambiri.
Ogula analinso ndi nkhawa kuti njirazi zinasintha kakomedwe ka khofi.
“Chinthu chimodzi chomwe tidazindikira pamsika wanthawi zonse wa decaf chinali chakuti nyemba zomwe amagwiritsa ntchito nthawi zambiri zinali zitatha kale, nyemba zakale za mbewu zakale,” akutero Juan Andres, yemwe amagulitsanso khofi wapadera.
"Choncho, njira ya decaf nthawi zambiri inali yokhudza kubisa zokometsera za nyemba zakale, ndipo izi ndi zomwe msika unkapereka," akupitiriza.
Khofi wa Decaf wakula kwambiri m'zaka zaposachedwa, makamaka pakati pa Millennials ndi Generation Z, omwe amakonda mayankho azaumoyo kudzera muzakudya komanso moyo.
Anthuwa amakonda kwambiri zakumwa zopanda caffeine pazifukwa za thanzi, monga kugona bwino komanso kuchepetsa nkhawa.
Izi sizikutanthauza kuti caffeine ilibe phindu;Kafukufuku wasonyeza kuti 1 mpaka 2 makapu a khofi amatha kulimbikitsa tcheru ndi kulingalira bwino.M'malo mwake, cholinga chake ndi kupereka zosankha kwa anthu omwe angakhudzidwe kwambiri ndi caffeine.
Njira zowongolera zochepetsera khofi zathandiziranso kusungidwa kwa khofi wachilengedwe, zomwe zimathandizira kutchuka kwa mankhwalawa.
"Nthawi zonse pakhala pali msika wa khofi wa decaf, ndipo khalidwe lake lasintha," akutero Juan Andres.“Zinthu zoyenerera zikagwiritsidwa ntchito pochotsa nzimbe, zimawonjezera kukoma ndi kukoma kwa khofiyo.”
"Ku Sucafina, EA decaf yathu ikupereka mosalekeza pa 84 point SCA target," akupitiriza.
Kodi ntchito yopanga nzimbe imagwira ntchito bwanji?
Kofi ya Decaffeinating nthawi zambiri ndi njira yovuta yomwe imafuna ntchito zamakampani apadera.
Kufunafuna njira zathanzi, zokhazikika kunayamba pomwe makampani a khofi adachoka ku njira zosungunulira.
Njira ya Swiss Water, yomwe idayamba ku Switzerland cha m'ma 1930 ndikupeza bwino pazamalonda m'ma 1970, ndi imodzi mwanjira zotere.
Njira ya Swiss Water ndikuviika nyemba za khofi m'madzi kenako ndikusefa madzi ochuluka a caffeine kudzera mu activated carbon.
Amapanga khofi wopanda caffeine wopanda mankhwala kwinaku akusunga magwero ake apadera komanso kakomedwe kake.
Dongosolo la supercritical carbon dioxide ndi njira ina yopindulitsa kwambiri yochepetsera caffeine.Njira imeneyi imaphatikizapo kusungunula molekyulu ya caffeine mu carbon dioxide yamadzimadzi (CO2) ndikuyitulutsa munyemba.
Ngakhale izi zimapanga chopereka chosalala cha decaf, khofi imatha kulawa mopepuka kapena yosalala nthawi zina.
Njira yopangira nzimbe, yomwe idachokera ku Colombia, ndiyo njira yomaliza.Kuti muchotse caffeine, njirayi imagwiritsa ntchito molekyulu yopezeka mwachilengedwe ethyl acetate (EA).
Khofi wobiriwira amatenthedwa ndi mphamvu yochepa kwa mphindi 30 asanalowe mu EA ndi madzi.
Nyemba zikafika pamlingo womwe umafunidwa, thanki yamadzimadzi imatsanulidwa ndikuwonjezeredwa ndi njira yatsopano ya EA.Njirayi imachitika kangapo mpaka nyemba zitakhala ndi caffeine mokwanira.
Nyembazo zimatenthedwa kuti zichotse EA yotsalayo isanaumidwe, kupukutidwa, ndi kupakidwa kuti igawidwe.
Ethyl acetate yomwe imagwiritsidwa ntchito imapangidwa pophatikiza nzimbe ndi madzi, ndikupangitsa kuti ikhale yosungunulira yathanzi ya decaf yomwe siyisokoneza kukoma kwachilengedwe kwa khofi.Makamaka, nyemba zimasunga kutsekemera pang'ono.
Kutsitsimuka kwa nyemba ndi chimodzi mwazinthu zofunika kwambiri pakuchita izi.
Kodi owotcha khofi ayenera kugulitsa decaf ya nzimbe?
Ngakhale akatswiri ambiri apadera a khofi amagawanika pa kuthekera kwa premium decaf, zikuwonekeratu kuti pali msika womwe ukukulirakulira.
Owotcha ambiri padziko lonse lapansi tsopano akupereka khofi yapadera ya decaf, zomwe zikutanthauza kuti amadziwika ndi Specialty Coffee Association (SCA).Kuphatikiza apo, owotcha ochulukirachulukira akusankha njira yowotcha nzimbe.
Owotcha khofi ndi eni khofi angapindule mwa kuwonjezera khofi wa decaf ku malonda awo pamene kutchuka kwa khofi wa decaf ndi ndondomeko ya nzimbe zikukula.
Owotcha ambiri akhala ndi mwayi wokhala ndi nyemba za nzimbe, podziwa kuti zimawotcha ndi thupi lapakati komanso acidity yochepa.Chikho chomaliza nthawi zambiri chimakongoletsedwa ndi chokoleti cha mkaka, tangerine, ndi uchi.
Kukoma kwa nzimbe kuyenera kusungidwa bwino ndi kuikidwa m'matumba kuti ogula amvetsetse ndikuyamikira.
Khofi wanu wa nzimbe wa nzimbe apitiliza kumveka bwino ngakhale mutamaliza chifukwa cha njira zina zopangira zinthu zachilengedwe monga kraft kapena pepala la mpunga lokhala ndi PLA mkati.
Njira zina zopangira khofi zopangidwa kuchokera kuzinthu zongowonjezedwanso monga mapepala a kraft, pepala la mpunga, kapena ma LDPE amitundu yambiri okhala ndi lining eco-friendly PLA akupezeka ku Cyan Pak.
Kuphatikiza apo, timapatsa owotcha athu ufulu wakulenga powalola kupanga zikwama zawo za khofi.Izi zikutanthauza kuti titha kukuthandizani popanga matumba a khofi omwe amawonetsa kusiyana kwa khofi wa nzimbe wa nzimbe.
