Intshayelelo: Ukunyuka kweengxowa ze-PE Ziplock kwiNkqubo yokuGcina ukutya yanamhlanje
Kwihlabathi lanamhlanje elikhawulezayo, ukugcinwa kokutya akupheleli nje ekwandiseni ixesha lokugcinwa—yinto ebalulekileyo yokugcina impilo nokhuseleko. Ukususela kwiikhitshi zasekhaya ezixakekileyo ukuya kwiindlela zangaphandle, izisombululo ezilungelelanisa ukulula kunye nococeko zifunwa kakhulu.Iingxowa ze-PE zokutya ezivaliweyo(iingxowa ze-polyethylene ziplock) ziye zavela njengokhetho oluphezulu kumakhaya nakwimizi-mveliso yokutya ngokufanayo, ngenxa yeempawu zazo ezikhethekileyo zezinto. Eli nqaku lihlola isizathu sokuba i-PE ivelele "njengomkhuseli wokhuseleko" kwindawo yokugcina ukutya kunye nexabiso layo elisebenzayo elingenakuthelekiswa nanto.
Iingenelo zezinto ze-PE: Ukhuseleko kunye nokusebenza zidityanisiwe
1.Isiqinisekiso Esingenabungozi kunye neSigaba sokutya
I-PE (i-polyethylene) yeyona plastiki isetyenziswa kakhulu eqinisekisiweyo yi-I-FDA yokunxibelelana kokutya. Ulwakhiwo lwayo oluzinzileyo lweemolekyuli luqinisekisa ukuba ayinazo iiplastiki, i-BPA, okanye ezinye iikhemikhali eziyingozi. Nokuba igcina ukutya komntwana okanye isuphu zokufudumeza, iingxowa ze-PE azikhuphi zityhefu, nto leyo eqinisekisa ukhuseleko ukusuka kwimveliso ukuya ekusetyenzisweni kwemihla ngemihla.
2.Itekhnoloji yokutywina eneZintlu ezintathu
Iingxowa ze-PE ziplock zineziphu etyibilikayo enelungelo elilodwa lomenzi kunye nokuvalwa okunesitayile se-texturedukhuseleko olungangenisi moya, olungangeni manzi, noluthintela iintsholongwane:
- Ithintela ioksijini ukuze icothise ioksijini (umz., ukuthintela ukudaka kweziqhamo).
- Iyamelana nokufuma ukuze izinto ezomileyo zihlale ziqinile.
- Imiphetho evalwe kabini ithintela ukungcoliswa kweefriji.
3.Ukumelana nobushushu obugqithisileyo (-40°C ukuya kwi-110°C)
Ukuguquguquka kwe-PE kuqinisekisa ukuthembeka kwiimeko ezinzima:
- Ikhuselekile kwifriji: Ayinazimfanta nokuba ikwi--40°C, igcina inyama ukuya kuthi ga kwiinyanga ezi-3.
- Ayinabushushu: Ikhuselekile kwi-microwave xa inyibilikiswa (amandla aphantsi/aphakathi) okanye isetyenziswe njengomaleko ongangeni manzi xa upheka kwi-sous-vide.
Uthelekiso lwezinto: Kutheni i-PE iphumelela ngcono kunezinye iindlela
| Izinto eziphathekayo | ukhuseleko | Ixabiso | Amatyala angcono okusetyenziswa |
|---|---|---|---|
| PE | Ayinabungozi, ingasetyenziswa kwakhona | $0.04-0.07/ibhegi | Ukugcinwa kwemihla ngemihla, ukukhenkceza, ukuhamba |
| I-PVC | Isekelwe kwi-chlorine, inobungozi | $0.03-0.06/ibhegi | Ezemizi-mveliso (ezingezizo zokutya) |
| I-silicone | Ikhuselekile kodwa kulula ukuyicoca | $0.70-1.10/ibhegi | Ukupheka ngobushushu obuphezulu, ukuphinda usebenzise |
Qaphela: I-PVC ithintelwe kwi-EU ekupakisheni ukutya ngenxa yokukhululwa kwe-dioxin.
