Munguva ichangopfuura, vamwe vatengi vakabvunzana nezvekuti vangatenga seivacuum packagedchikafu.Zvinonzwisiswa kuti pari zvino, kune nzira nhatu dzekuchengetedza chikafu chitsva: kuzadza nenitrogen, vacuuming uye kuwedzera zvinodzivirira.Vacuum kuchengetedza iri nyore, yakasikwa uye ine hutano.
Vacuum packaging zvinoreva kutivacuum packaging baginopedzisa iyo yekupedzisira fomu yezvakaputirwa mukati mumushini wekurongedza vacuum.Imwe yezvibatanidza zvakakosha ndeyekutorwa kwemhepo uye deoxidization, ndiko kudzivirira chikafu kubva mukuvhu uye kuora.Rimwe basa rakakosha revacuum deoxidization nderokudzivirira chikafu chekudya.Semuenzaniso, chikafu chemafuta chine huwandu hwakawanda hweunsaturated fatty acids, izvo zviri nyore kushandura ruvara uye kuravira neoxidation.Vacuum yekuisa chisimbiso inogona kunyatsoparadzanisa mhepo kubva kune oxidation, uye kuchengetedza ruvara, kuravira uye hutano kukosha kwechikafu.
Zvakakosha kucherechedza izvozvovacuum packagingpachayo haina sterilization effect.Kuti unyatsotora mukana wezvakanakira zvevacuum packaging tekinoroji, zvinodikanwa zvakare kuita sterilization inodiwa mushure mekupedzwa kwevacuum packaging, senge yakakwira-tembiricha sterilization, irradiation sterilization, nezvimwe. Chero chikafu chinoparara chinoda kuiswa mufiriji. inofanirwa kunge ichiri firiji kana kuomeswa nechando mushure mekuvhara vacuum.Vacuum packaging haisi imwe nzira kune firiji kana kuchengetedza nechando.Uyezve, nguva yekuchengetedza vacuum yezvinhu zvekudya zvakachengetwa patembiricha dzakasiyana zvakasiyana.
Nzira yekusarudza yakachengetekavacuum packagedchikafu?
Kutanga, cherechedza bhegi rakazvimba
Kunyangwe kuwedzera bhegi ndiyo yakanyanya intuitive uye iri nyore nzira yekuti vatengi vaone kana iyokudya vacuum packagingyadzikira.Zvinoenderana nepfungwa yakajairika yefizikisi, mumamiriro ezvinhu akajairwa, mweya wemhepo uri mubhegi rekudya rakapetwa unofanirwa kuenderana nekunze kana kushoma pane yekunze mushure mekutsvaira.Kana bhegi ichiwedzerwa, zvinoreva kuti mhepo yemhepo muhombodo yakakwirira kudarika nyika yekunze, izvo zvinoreva kuti magasi matsva anogadzirwa muhomwe yakavharwa.Aya magasi ndiwo mametabolites anogadzirwa mushure mekukura kwehuwandu hwehutachiona, nokuti zvishoma zve microbial metabolites hazvina kukwana kuwedzera bhegi.Mazhinji mabhakitiriya kana molds (lactic acid bacteria, yeast, aerogenes, polymyxobacillus, Aspergillus, etc.) iyo inogona kukonzera huwori hwekudya inoburitsa huwandu hukuru hwemagasi mukuora kweprotein neshuga muchikafu, senge kabhoni dhaikisaidhi, hydrogen sulfide, ammonia, alkane, nezvimwewo, iyo "inofuridza" bhegi rekurongedza mubharumu.Munguva yekuita sterilization yechikafu isati yarongedza, ma microorganisms uye buds hazvina kuurayiwa zvachose.Mushure mokurongedza, utachiona hunowedzera muhuwandu, hunokonzera uori.Nomuzvarirwo, dambudziko rekuputika kwemabhegi ekurongedza rinoitika.
Chechipiri, kunhuwa
Kana uchitengavacuum packagedchikafu, usatora hwema hwechikafu semuyero wekutonga.Kana kunhuhwirira kwechikafu kuchibuda kunze kwekurongedza, zvinoreva kuti iyovacuum packagingpachayo haisisiri vacuum, uye kune kubuda kwemhepo.Izvi zvinoreva kuti mabhakitiriya anogonawo "kuyerera" zvakasununguka.
Chechitatu, zviratidzo zvekuongorora
Kuti utore pasuru yechikafu, tanga watarisa kana rezinesi rayo rekugadzira, SC kodhi, mugadziri uye ingredient runyorwa rwakakwana.Zvitupa izvi zvakaita se“ID makadhi” echikafu.Seri kwezvitupa kune “upenyu hwekare nehwazvino” hwechikafu, kwavakabva nekwavave vari.
Chechina, nyatsoteerera pasherufu yehupenyu hwekudya
Chikafu chiri pedyo nehupenyu hwesherufu hachina kukuvadza, asi ruvara rwayo uye kudya kunoderera.Mushure mevacuum packagedzvokudya zvinovhurwa, zvinofanira kudyiwa nokukurumidza sezvinobvira uye hazvifaniri kuchengetwa mufiriji.Paunenge uchitenga "tenga imwe uwane imwe yemahara" chikafu, teerera kune zuva rekugadzira uye hupenyu hwesherufu hwezvinhu zvakasungwa.
