Nkuko icyayi ari igihingwa gisanzwe, bimwe mubintu byacyo biganisha ku gupakira icyayi gikomeye.
Kubwibyo, gupakira icyayi bifite ibisabwa byo kurwanya okiside, kutagira ubushyuhe, kurwanya ubushyuhe bwinshi, igicucu na gaze.
Kurwanya okiside
Umwuka mwinshi wa ogisijeni uri muri paki uzatuma okiside yangirika mubice bimwe na bimwe byicyayi. Kurugero, ibintu bya lipide bizahindura okisijene hamwe na ogisijeni mu kirere kugirango bitange aldehydes na ketone, bityo bitange impumuro mbi. Kubwibyo, umwuka wa ogisijeni mu gupakira icyayi ugomba kugenzurwa neza munsi ya 1%. Kubijyanye na tekinoroji yo gupakira, gupakira ibicuruzwa cyangwa gupakira vacuum birashobora gukoreshwa kugirango ugabanye ogisijeni. Tekinoroji yo gupakira vacuum nuburyo bwo gupakira bushyira icyayi mumifuka yoroheje yo gupakira (cyangwa umufuka wa aluminium foil vacuum) ufite umwuka mwiza, ukuraho umwuka mumufuka mugihe cyo gupakira, ugakora urwego runaka rwa vacuum, hanyuma ukabifunga; Tekinoroji yo gupakira yaka ni ukuzuza imyuka ya inert nka azote cyangwa deoxidizer mugihe usohora umwuka, kugirango urinde umutekano wamabara, impumuro nziza nuburyohe bwicyayi kandi ugumane ubwiza bwumwimerere.
Kurwanya ubushyuhe bwinshi.
Ubushyuhe ni ikintu cyingenzi kigira ingaruka nziza ku cyayi. Itandukaniro ryubushyuhe ni 10 ℃, kandi igipimo cyimiti itandukanye inshuro 3 ~ 5 zitandukanye. Icyayi kizongera ingufu za okiside yibirimo munsi yubushyuhe bwinshi, bigatuma igabanuka ryihuse rya polifenol nibindi bintu bifatika kandi byihuta kwangirika. Ukurikije ishyirwa mubikorwa, ubushyuhe bwo kubika icyayi munsi ya 5 ℃ nibyiza. Iyo ubushyuhe ari 10 ~ 15 ℃, ibara ryicyayi rizagabanuka buhoro, kandi ingaruka yamabara nayo irashobora kugumaho. Iyo ubushyuhe burenze 25 ℃, ibara ryicyayi rizahinduka vuba. Kubwibyo, icyayi gikwiriye kubikwa mubushyuhe buke.
Ubushuhe
Amazi arimo icyayi nuburyo bwo guhindura ibinyabuzima byicyayi, kandi amazi make arafasha kubungabunga ubwiza bwicyayi. Amazi arimo icyayi ntagomba kurenga 5%, kandi 3% nibyiza kubikwa igihe kirekire, bitabaye ibyo aside aside ya asikorbike mucyayi iroroshye kubora, kandi ibara, impumuro, nuburyohe bwicyayi bizahinduka, cyane ku bushyuhe bwo hejuru, igipimo cyo kwangirika kizihuta. Kubwibyo, mugihe cyo gupakira, turashobora guhitamo firime ikomatanya hamwe nibikorwa byiza bitarinda ubushuhe, nka aluminium foil cyangwa aluminium foil evaporation firime nkibikoresho byibanze byo gupakira neza.
igicucu
Umucyo urashobora guteza okiside ya chlorophyll, lipide nibindi bintu mucyayi, byongera glutaraldehyde, propionaldehyde nibindi bintu binuka mubyayi, kandi byihutisha gusaza kwicyayi. Kubwibyo, mugihe upakira icyayi, urumuri rugomba gukingirwa kugirango hirindwe fotokatalitike ya chlorophyll, lipide nibindi bice. Byongeye kandi, imirasire ya ultraviolet nayo ni ikintu cyingenzi gitera icyayi kwangirika. Kugira ngo iki kibazo gikemuke, tekinoroji yo gupakira irashobora gukoreshwa.
Choke
Impumuro yicyayi iroroshye kuyikwirakwiza, kandi irashobora kwibasirwa numunuko wimpumuro yo hanze, cyane cyane ibisigisigi bisigara bya membrane hamwe numunuko wangirika no kuvura ubushyuhe bizagira ingaruka kuburyohe bwicyayi, bizagira ingaruka kumpumuro yicyayi. Kubwibyo, gupakira icyayi bigomba kwirinda guhumura impumuro nziza mubipfunyika no kunuka umunuko uturutse hanze. Ibikoresho byo gupakira icyayi bigomba kuba bifite imiterere ya gaze.
