Patinoshanyira nzvimbo nyowani dzekudya, tichawana akawanda marudzi akasiyana ekurongedza, kubva kunamatira firimu tray kurongedza, akasarudzika-akasungwa-kurongedza kutevedzera, mvura inopisa inodzika,vacuum ganda remaganho, uye zvichingodaro, vatengi vanogona kusarudza chero nzira yekurongedza zvigadzirwa zvinoenderana nezvavanofarira uye zvavanoda. Saka ndedzipi misiyano pakati peiyi dzakasiyana kurongedza?

Kunamatira mafirimu ekukoka

Nyama nyowani yakaiswa pombi yepurasitiki uye yakafukidzwa nepurasitiki yekuputira, ndeipi nzira yakanyanya kunaka yakaiswa. Nekuda kwemutengo wayo wepazasi, panguva imwecheteyo ipa munhu ane "kunaka" kunzwa - tsvuku yakanaka.

Chikonzero cheiyo ruvara rutsvuku ruvara nderekuti kurongedza kune oxygen, asi kuratidzwa kwenyama nyowani kune oksijeni kuri kuwedzerawo kushatisa kwavo. Naizvozvo, rudzi urwu rwechitsva nyama ratidziro ine hupenyu hupfupi uye hunofanira kudyiwa mukati memazuva mashoma, kana chando muhomwe yakasungwa isina okisijeni kuti udzivise kupfava.

Yakagadziriswa mamiriro ekunze pakutakura

Yakagadziriswa mamiriro ekunze pakurongedza uye kunamatira mapepa ekurongedza tarisa zvakafanana pakuonekwa, zvese zvinotora tray uye firimu. Musiyano wacho ndewekugadziriswa mamiriro ekunze anobvisa mweya kubva muhomwe uye achizadza uye anotsiva yakasarudzika gasi musanganiswa kuti ubatsire kudzora mabhakitiriya, achiri kuoneka tsvuku. Yakagadziriswa mamiriro ekunze ekutakura anogona kuwedzera zvakanyanya hupenyu hwesherufu.

Vacuum packaging

Vacuum pairatidziro ine hupenyu hwakareba hwesherufu pakati pemhando dzepamusoro dzemhando yepamusoro, asi ichakanganisa kutaridzika kwenyama. Ruvara rwevavha rwevhu redying nyama yeiyo purlish tsvuku, kwete tsvuku tsvuku.

Vacuum ganda remaganho

Vacuum ganda remaganho Kune nyama nyowani inogona kugadzira iyo isina kunaka yekuona ruzivo rwakaunzwa nenyama yepepuru kune imwe nhanho. Nekuda kweiyo yakanaka uye yakakwirira-yekupedzisira chitarisiko, inogona kusimudzira kutaridzika uye kunzwa kwepepuru yenyama. Izvo hazvingabudisi chete hupenyu hweshimita refu asi hunogutsawo kunakidzwa kwekutaridzika uye kuona.
