Ngokutya kwezilwanyana zasekhaya ezimbalwa ezitsha ezingena emarikeni, ukutya kwezilwanyana zasekhaya kuye kwahlala kulelona shishini likhuphisanayo.
Iindlela ezithembekileyo ziya zifuneka ngakumbi ukuqinisekisa kunye nokwandisa ubomi beshelufu yokutya kwesilwanyana.
Njengokutya kwabantu, ukutya kwesilwanyana kufuneka kuqinisekise ukuba kuyahlangabezana nobomi kunye nempilo yesilwanyana sasekhaya.
Ke ngoko, ukutya kwesilwanyana kufuneka kugcine isondlo esiyimfuneko kunye nencasa yokuqala ngaphakathi kokuhanjiswa, ukugcinwa kunye nobomi beshelufu.
Izinto zokukhusela ziye zasetyenziswa kangangeenkulungwane.
Basenokuba.
Izithinteli zeMicrobial ezithintela ukukhula kweebhaktheriya kunye nefungi, okanye i-antioxidants evimbela i-oxidation yezithako zokutya, ezifana ne-oxygen absorbers. I-anti eqhelekileyo
Izithinteli zeMicrobial ziquka i-C-calcium, i-sodium nitrate, i-nitrite, kunye ne-asidi ye-sulfuric (
Sulfur dioxide, sodium bisultan, potassium bisultan, njl.
Kwaye disodium.
Ii-Antioxidants ziquka i-BHA kunye ne-BHT.
Izilondolozo zokutya zihlulwe zibe: izigcini zendalo ezifana netyuwa, iswekile, iviniga, isiraphu, iziqholo, ubusi, ioli edliwayo, njl.
Kwaye izigcini zeekhemikhali ezifana nesodium okanye i-potassium, i-sulfate, i-glutamate, i-gan grease, njl.
Nangona kunjalo, iziphumo ebezingalindelekanga zezithinteli ezenziweyo ekutyeni kwesilwanyana zinobuzaza ngakumbi kunezigcina-ndalo zendalo.
Ngokubhekiselele kuhlobo kunye nobungakanani bongezwa ekudleni kwezilwanyana, kukho imimiselo engqongqo.
Kuya kusiba nzima ukuba abavelisi baxhomekeke kwizigcina-lwazi ukuqinisekisa ubomi beshelufu.
Ukusetyenziswa kwezixhobo eziphezulu zokuthintelwa njengokupakishwa kokutya kwesilwanyana kuluncedo kakhulu ekuqinisekiseni kunye nokwandisa ubomi beshelufu yokutya kwesilwanyana.
Kuyaziwa ukuba ukukhula kwee-microorganisms kufuna indawo efanelekileyo.
Ubushushu, ioksijini kunye namanzi zezona zinto zintathu zibalulekileyo.
Ioksijini ngoyena nobangela wokubola kokutya.
I-oksijini encinci kwi-package yokutya, kuya kuba lula ukuba ukutya kuya kubola.
Ngelixa amanzi ebonelela ngemekobume ephilayo kwi-microorganisms, inokukhawulezisa ukuncitshiswa kwamafutha;
Yenza bufutshane ubomi beshelufu yokutya kwesilwanyana.
Ngexesha leshelufu yokutya kwesilwanyana, ioksijini kunye nomphunga wamanzi kwiphakheji kufuneka zigcinwe zizaliswe kwangaphambili.
I-Permeability kukukwazi ukulinganisa igesi evumelekileyo ngezinto zokuthintela (
O2, N2, CO2, umphunga wamanzi, njl.
Ngena kuyo ngexesha elithile.
Ngokuqhelekileyo kuxhomekeke kuhlobo, uxinzelelo, ubushushu kunye nobukhulu bezinto eziphathekayo.
Kwilebhu yeLabthink, sivavanye, sihlalutye kunye ne-OPP / PE / CPP, izinga lokudluliselwa kwe-oksijini kunye nesantya sokudlulisa umphunga wamanzi kwi-7 esetyenziswa ngokuqhelekileyo ukupakishwa kokutya kwesilwanyana i-PET, i-pet CPP, i-Bopp / CPP, i-BOPET / PE / VMPET / dlp.
Izinga eliphezulu lokungena kweoksijini lithetha ukuba ukungenwa kwe-oksijini kuyancipha;
Izinga lokuhanjiswa komphunga wamanzi aphezulu lithetha ukuba umphunga wamanzi ufikeleleka kwizinto eziphathekayo.
Uvavanyo lokuhanjiswa kweoksijini lwamkela inkqubo yovavanyo lokuhanjiswa kwe-oksijini yeLabthink OX2/230, indlela yoxinzelelo elinganayo.
Beka isampuli kwindawo eqhelekileyo phambi kovavanyo (23±2℃,50%RH)
Kwiiyure ezingama-48, ibhalansi yomoya phezu kwesampulu.
Uvavanyo lokuhanjiswa komphunga wamanzi lusebenzisa iLabthink/030 yokuvavanya izinga lokuhambisa umphunga wamanzi kunye nendlela yeNdebe yesintu.
Iziphumo zovavanyo ezineenkcukacha ze-OTR kunye ne-WVTR zezi zinto zi-7 zokupakishwa zilandelayo: iziphumo zesampula ze-OTR (ml/m2/day) WVTR (g/m2/24h)PET/CPP 0. 895 0.
667 BOPP/CPP 601. 725 3. 061 PET 109. 767 25.
BOPET/PE 85 163. 055 4.
632 OPP/PE/CPP 716. 226 2.
214 BOPET/VMPET/hdpe 0. 149 0. 474 Aluminium-plastiki 0. 282 0.
I-187 Itheyibhile 1 ukusuka kuhlalutyo lweziphumo zovavanyo lwezi zixhobo ze-7 zokupakisha, idatha yokuvavanya ukunyanzeliswa kokupakishwa kokutya kwe-Pet ingafumaneka, kwaye sinokufumanisa ukuba izinto ezahlukeneyo ze-laminated ziya kuba nentlukwano enkulu kwi-oxygen permeability.
Ukusuka kwiTheyibhile 1, ialuminiyam-
Amazinga okudluliselwa kwe-oksijeni kwizinto zeplastiki, i-BOPET / VMPET / dlp, i-PET / CPP iphantsi.
Ngokophando lwethu, ukutya kwezilwanyana zasekhaya kule phakheji kuqhele ukubanobomi obude beshelufu.
Ifilimu elayitiweyo inomsebenzi omhle wokuthintela umphunga wamanzi.
Jonga kumfanekiso ongezantsi, i-PET inezinga eliphezulu lokuhambisa umphunga wamanzi, oku kuthetha ukuba umqobo wayo womphunga wamanzi unokusebenza kakubi kwaye ayifanelekanga ukupakishwa kokutya kwe-PET kuba iya kunciphisa ubomi beshelufu yokutya kwe-PET.
Abavelisi bokutya kwezilwanyana zasekhaya banokusebenzisa izixhobo eziphezulu zokuthintelwa endaweni yezithinteli ezininzi zokwandisa ubomi beshelufu yokutya kwesilwanyana.
Sincoma iplastiki elaminated, ialuminium-
Iplastiki kunye nezixhobo zentsimbi zipakishwe njengokutya kwesilwanyana kuba zonke zinezithintelo ezilungileyo kwioksijini kunye nomphunga wamanzi.
Ukongeza ekuqwalaseleni i-oksijini kunye neempawu zokungena komphunga wezinto eziphathekayo, kufuneka sazi ukuba okusingqongileyo kunempembelelo ethile kwezi mpawu zezinto.
Njengo-EVOH kunye ne-PA, banomdla kakhulu kumswakama.
Kwiqondo lobushushu begumbi kunye nokufuma okuphantsi ngokwentelekiso, zombini zinempembelelo entle yokuthintela kumphunga wamanzi, ngelixa umphunga wazo wamanzi umphunga wazo uphela kwiindawo zokufuma eziphezulu.
Ngoko ke, i-EVOH kunye ne-PA ayifanelekanga ukupakishwa ukuba kukho indawo yomswakama ophezulu ngexesha lokuthuthwa kokutya kwezilwanyana kunye nokugcinwa.
