Nyama itsva ine hupenyu hupfupi hwesherufu munzvimbo yayo yechisikigo uye zvinhu zvakawanda zvinogona kukonzera kuparara kwenyama, uye maindasitiri munyika dzakasiyana ari kutsvaga nzira dzekuwedzera hupenyu hwesherufu.Nhasi indasitiri yenyama muEurope neUnited States nekudzora zvinhu zvitatu zvakakosha, zvinoti tembiricha, hutsanana, kurongedza (shrink vacuum bag kurongedza) zvakabudirira kuwana hupenyu hwesherufu hwemwedzi mitatu yenyama yemombe yakakangwa uye mazuva makumi manomwe egwayana rakatonhora, nepo vacuum shrink mabhegi anogona kupa basa guru rekurongedza kwechivharo (gasi, mwando) uye shrinkage.Pano, kunyanya, maererano nekubata nyama inotonhora pamusoro pekuvapo kwezvinetso zvekuongorora kukanganisa kwe shrinkagevacuum bag kurongedzapasherufu yehupenyu hwenyama inotonhora.
1 Chipingamupinyi
1.1 Kudzivirira kuonda (kurasikirwa uremu)
Nyama itsva isina kurongedzerwa inorasikirwa nehuremu nekuda kwekurasikirwa kwemwando, iyo yakareba nguva yekuchengetedza, iyo yakanyanya kuomarara kurasikirwa.Kurasikirwa kwehuremu hakungoite kuti nyama ive yakasviba uye yakaipisisa kutaridzika, asi zvakare inokonzeresa kurasikirwa kwepurofiti kune vanogadzira, senge mabhegi anodonha.vacuum packagingyakavharwa, hunyoro hunogona kuchengetedzwa, hapazovi nechiitiko chekushaya mvura.
1.2 Inhibit microorganisms
1.3 Mira kuchinja kwemavara
1.4 Kudzoreredza rancidity (rancidity)
1.5 kudzora enzymes (enzyme; enzyme)
2 Shrinkage
Tsanangudzo pfupi yemabasa makuru.
1. shrinkage inobatsira kuderedza zvinhu zvakawandisa kunze kwepakeji, zvichiita kuti pasuru yacho iwedzere kutsvedza, kutaridzika kwakanaka, uye kuwedzera kunaka kwekutengesa kwenyama.
2. shrinkage inobvisa wrinkles yebhagi uye capillary water absorption inogadzirwa navo, nokudaro kuderedza kubuda kweropa kubva munyama.
3. shrinkage inogona kuwedzera kuwanda kwebhegi, nokudaro kuvandudza mhinganidzo yayo yeokisijeni uye kuwedzera hupenyu hwesherufu yenyama nyowani.Inoitawo kuti mabhegi awedzere kusimba uye kusapfeka.
4. simba rekuvhara rehomwe rinovandudzwa mushure mekuderera
5. mushure mekuderera, bhegi rinonyanya kusungirirwa kune nyama, richigadzira "ganda rechipiri".Kana bhegi racho rakaputsika nokusaziva, rinogona kuderedza zviri pachena kukanganisa kwenyama, kuitira kuti kurasikirwa kuderedzwa.
