Me ka liʻiliʻi o nā meaʻai pipi hou e komo ana i ka mākeke, ʻo ka meaʻai pipi kekahi o nā ʻoihana hoʻokūkū.
Pono nui nā ʻano hilinaʻi e hōʻoia a hoʻolōʻihi i ke ola o ka meaʻai holoholona.
E like me ka meaʻai kanaka, pono e hōʻoia ka meaʻai pipi i ke ola a me ke olakino o ka pipi.
No laila, pono e mālama ka meaʻai pipi i ka meaʻai kūpono a me ka ʻono mua i loko o ka lawe ʻana, mālama ʻia a me ke ola papa.
Ua hoʻohana ʻia nā preservatives no nā kenekulia.
ʻO lākou paha.
ʻO nā mea mālama microbial e pale ai i ka ulu ʻana o nā hua bacteria a me nā haʻani, a i ʻole nā antioxidant e pale i ka oxidation o nā meaʻai, e like me ka oxygen absorbers. Kūʻē maʻamau
ʻO nā mea mālama microbial ka C- calcium, sodium nitrate, nitrite, a me ka sulfuric acid (
Sulfur dioxide, sodium bisultan, potassium bisultan, etc.)
A me ka disodium.
Aia nā antioxidants i ka BHA a me ka BHT.
Hoʻokaʻawaleʻia nā mea mālama meaʻai i: nā mea mālama maoli e like me ka paʻakai, ke kō, ka vīneka, ka syrup, nā meaʻala, ka meli, kaʻailaʻai, a pēlā aku;
A me nā mea mālama kemika e like me ka sodium a i ʻole potassium, sulfate, glutamate, gan grease, etc.
Eia nō naʻe, ʻoi aku ka koʻikoʻi o nā hopena ʻaoʻao o nā mea hoʻomalu kūlohelohe i nā meaʻai holoholona ma mua o nā mea mālama kūlohelohe.
Ma ke ʻano o ke ʻano a me ka nui i hoʻohui ʻia i ka meaʻai holoholona, aia nā hoʻoponopono koʻikoʻi.
He mea paʻakikī i nā mea hana ke hilinaʻi i nā preservatives e hōʻoia i ke ola o ka papa.
ʻO ka hoʻohana ʻana i nā mea pale kiʻekiʻe e like me ka hoʻopili ʻana i ka meaʻai holoholona he mea kōkua nui e hōʻoia a hoʻonui i ke ola o ka meaʻai holoholona.
Ua ʻike maopopo ʻia ʻo ka ulu ʻana o nā microorganism e pono ai kahi ʻano kūpono.
ʻO ka mahana, ka oxygen a me ka wai nā kumu nui ʻekolu.
ʻO ka oxygen ke kumu nui o ka pala ʻai.
ʻO ka liʻiliʻi o ka oxygen i loko o ka pūʻolo meaʻai, ʻoi aku ka liʻiliʻi o ka pohō o ka meaʻai.
ʻOiai e hāʻawi ana ka wai i ka nohona ola no nā microorganisms, hiki iā ia ke wikiwiki i ka emi ʻana o ka momona;
E hoʻopōkole i ke ola o ka meaʻai holoholona.
I ka wā e mālama ʻia ai ka meaʻai pipi, pono e hoʻopiha mua ʻia ka oxygen a me ka mahu wai i loko o ka pūʻolo.
ʻO ka permeability ka hiki ke ana i ke kinoea i ʻae ʻia e nā mea pale (
O2, N2, CO2, wai mahu, etc.)
E komo i loko i kahi manawa kikoʻī.
ʻO ka mea maʻamau e pili ana i ke ʻano, ke kaomi, ka mahana a me ka mānoanoa o ka mea.
Ma Labthink lab, ua hoʻāʻo mākou, hoʻopaʻa ʻia a me OPP/PE/CPP, ka nui o ka hoʻololi ʻana o ka oxygen a me ka neʻe ʻana o ka mahu wai no 7 meaʻai meaʻai meaʻai maʻamau i hoʻohana ʻia PET, pipi CPP, Bopp/CPP, BOPET/PE/VMPET/dlp.
ʻO ka nui o ka oxygen permeability kiʻekiʻe, ʻo ia ka mea e hoʻemi ai i ka oxygen permeability mea;
ʻO ke kiʻekiʻe o ka hoʻoili ʻana o ka mahu wai, ʻo ia ka haʻahaʻa o ka wai permeability o ka mea.
Hoʻohana ka hoʻāʻo hāʻawi oxygen i ka Labthink OX2/230 oxygen delivery rate test system, ke ʻano kaomi like.
E kau i ka laʻana ma kahi kūlana maʻamau ma mua o ka hoʻāʻo ʻana (23 ± 2 ℃, 50% RH)
No 48 mau hola, ea kaulike ma ka ʻili o ka hāpana.
Ke hoʻohana nei ka hoʻāʻo ʻana o ka wai mahu wai i ka Labthink/030 water vapor transmission rate tester a me ke ʻano Cup kuʻuna.
ʻO nā hopena hōʻike kikoʻī OTR a me WVTR o kēia mau mea hoʻopihapiha 7 penei: OTR (ml/m2/lā）WVTR (g/m2/24h)PET/CPP 0. 895 0.

187 Papa 1 mai ka ho'āʻoʻana i nā hopena ho'āʻo o kēia mau mea hōʻailona 7, hiki ke loaʻa kaʻikepili ho'āʻo o ka permeability o Pet food packaging, a hiki iā mākou keʻike i nā mea laminated likeʻole e loaʻa nāʻokoʻa nui i ka oxygen permeability.
Mai ka Papa 1, alumini-
He haʻahaʻa haʻahaʻa nā uku hoʻoili o ka oxygen no nā mea plastik, BOPET/VMPET/dlp, PET/CPP.
Wahi a kā mākou noiʻi, ʻoi aku ka lōʻihi o ka mālama ʻana i ka meaʻai pipi i loko o kēia pūʻolo.
He hana maikaʻi ke kiʻi laminated i ka pale ʻana i ka mahu wai.
E nānā i ke kiʻi ma lalo nei, he kiʻekiʻe ka nui o ka lawe ʻana i ka mahu wai ʻo PET, ʻo ia hoʻi he maikaʻi ʻole ka hana ʻana o kāna pahu mahu wai a ʻaʻole kūpono no ka ʻeke meaʻai PET no ka mea e pōkole ke ola o ka meaʻai PET.
Hiki i nā mea hana meaʻai holoholona ke hoʻohana i nā mea pale kiʻekiʻe ma mua o nā mea mālama ʻē aʻe e hoʻonui i ke ola o ka meaʻai holoholona.
Paipai mākou i ka plastic laminated, aluminika-
Hoʻopili ʻia nā mea palaki a me nā mea metala e like me ka meaʻai holoholona no ka mea he pale maikaʻi lākou āpau i ka oxygen a me ka mahu wai.
Ma waho aʻe o ka noʻonoʻo ʻana i nā waiwai o ka oxygen a me ka wai vapor permeability o ka mea, pono mākou e ʻike i ka hopena o ke kaiapuni i kēia mau waiwai o ka mea.
E like me EVOH a me PA, paʻakikī loa lākou i ka haʻahaʻa.
Ma ka lumi wela a me ka haʻahaʻa haʻahaʻa, loaʻa iā lāua ka hopena pale maikaʻi i ka mahu wai, aʻo ka emi ʻana o kā lākou mahu wai permeability i nā wahi haʻahaʻa kiʻekiʻe.
No laila, ʻaʻole kūpono ʻo EVOH a me PA no ka hoʻopili ʻana inā loaʻa kahi wahi haʻahaʻa kiʻekiʻe i ka wā o ka lawe ʻana a me ka mālama ʻana i nā meaʻai holoholona.
