Ruzivo rweKofi - Michero neMbeu dzeKofi
Mbeu dzekofi nemichero ndizvo zvinhu zvikuru zvinogadzirwa pakugadzira kofi. Dzine maumbirwo akaomarara emukati uye makemikari akawanda, izvo zvinokanganisa zvakananga kunaka uye kunaka kwezvinwiwa zvekofi.
Kutanga, ngatitarisei chimiro chemukati memichero yekofi. Michero yekofi inowanzonzi macheri ekofi, uye kunze kwayo kunosanganisira ganda, pulp, uye endocarp. ganda ndiro chikamu chekunze checherry, pulp ndiro chikamu chinotapira checherry, uye endocarp ndiro firimu rinoputira mhodzi. Mukati me endocarp, munowanzova nembeu mbiri dzekofi, idzo dzinonziwo bhinzi dzekofi.
Mbeu dzekofi nemichero zvine makemikari akasiyana-siyana, chinonyanya kukosha icaffeine. Caffeine ialkaloid yechisikigo ine simba rekukurudzira tsinga uye ndiyo chinhu chikuru chiri muzvinwiwa zvekofi chinoita kuti vanhu vafare. Pamusoro pecaffeine, mbeu dzekofi nemichero zvakapfumawo mune ma antioxidants, akadai se polyphenols uye amino acids, izvo zvinobatsira hutano hwevanhu.
Panyaya yekugadzirwa kwekofi pasi rose, zvichienderana nedata kubva kuInternational Coffee Organization (ICO), kugadzirwa kwekofi pagore pasi rose kunosvika mabhegi angangoita mamiriyoni zana (60 kg/bhegi), ayo kofi yeArabica inokwana 65%-70%. Izvi zvinoratidza kuti kofi ndeimwe yezvinwiwa zvinonyanya kufarirwa pasi rose uye ine kukosha kukuru kuhupfumi hwenyika.
Zvikonzero zvekuvava kwekofi
Chimwe chezvinhu zvinokonzera kuvava kwekofi ibrown pigments. Ma brown pigments makuru ane molecular achava nekuvava kwakasimba; sezvo nzira yekugocha ichikura, huwandu hwebrown pigments hunowedzerawo, uye huwandu hwebrown pigments huru huchawedzerawo zvinoenderana, saka kuvava uye magadzirirwo ekofi yakakangwa zvakanyanya kuchawedzera.
Chimwe chikonzero chekuvava kwekofi i "cyclic diamino acids" inoumbwa nemaamino acids nemapuroteni mushure mekudziya. Maumbirwo emamorekuru avanoumba akasiyana, uye kuvava kwakasiyanawo. Kuwedzera kune kofi, cocoa nedoro rakasviba zvinewo zvinhu zvakadaro.
Saka tinogona kudzora mwero wekuvava here? Mhinduro yacho ndeyechokwadi. Tinogona kudzora kuvava nekushandura mhando yekofi, mwero wekugocha, nzira yekugocha, kana nzira yekuburitsa.
Kofi inonaka sei kuvava?
Zvinoshandiswa mubhinzi dzekofi zvinosanganisira citric acid, malic acid, quinic acid, phosphoric acid, nezvimwewo. Asi uku hakusi kunaka kwatinoita patinonwa kofi. Kunaka kwatinoita kunonyanya kubva muacid inogadzirwa panguva yekugocha.
Pakugocha bhinzi dzekofi, zvimwe zvikamu zviri mubhinzi zvinosangana nemakemikari kuti zvigadzire maasidhi matsva. Muenzaniso wakajeka ndewekuti chlorogenic acid inoora kuti igadzire quinic acid, uye oligosaccharides inoora kuti igadzire volatile formic acid uye acetic acid.
Asidhi yakanyanya mubhinzi dzakakangwa iquinic acid, iyo inowedzera sezvo kugocha kuchidzika. Haingori nehukuru hwayo chete, asiwo ine kuravira kwakasimba kwekuvava, uko kuri iko kunobva kukosha kwekofi. Zvimwe zvakaita secitric acid, acetic acid, uye malic acid zvinewo zvakawanda mukofi. Simba uye hunhu hwemaasidhi akasiyana siyana zvakasiyana. Kunyangwe ese ari akaoma, zvinhu zvawo zvakaoma chaizvo.
Mabudiro anoita kuravira kwekuvava akasiyana zvichienderana nemamiriro epatani yacho. Pane chinhu chiri mu quinic acid chinogona kuburitsa kuravira kwekuvava uye kuviga kuravira kwekuvava. Chikonzero chinoita kuti kofi yakabikwa iwedzere kuvava ndechekuti kuvava kwacho kwaimbovanzwa kunopera zvishoma nezvishoma nekufamba kwenguva.
Kuti bhinzi dzekofi dzirambe dzichinaka, unofanira kutanga wawana mukana wekurongedza zvinhu zvemhando yepamusoro uye mutengesi wekurongedza zvinhu zvine kugadzirwa kwakasimba.
Tiri vagadziri vane hunyanzvi mukugadzira mabhegi ekurongedza kofi kwemakore anopfuura makumi maviri. Tava mumwe wevagadziri vakuru vemabhegi ekofi muChina.
Tinoshandisa mavharuvhu eWIPF emhando yepamusoro kubva kuSwiss kuti kofi yenyu igare yakachena.
Tagadzira mabhegi asingakuvadzi nharaunda, akadai semabhegi anogadziriswa manyowa nemabhegi anogona kudzokororwa, pamwe nezvinhu zvitsva zvePCR zvakaunzwa.
Kana uchida kuona chitupa cheYPAK, ndapota tinya kuti utibate.
