ʻO ke kaʻina hana o ka mīkini hoʻopaʻa meaʻai meaʻai penei:
ʻO ka uhi ʻana o ke keʻena ʻāwīwī, ka pauma ʻūhā, hoʻomaka ke keʻena ʻeleʻele e hoʻoheheʻe i ka ea i loko o ka moku maloʻo, nā ʻeke i loko o ka ʻūhā i ka manawa like, e piʻi aʻe ka mea kikoʻī ʻana i ka ʻōpala (
Ma ka manawa hoʻokuʻu i ka mana ISJ)
Pau ka hana ʻana o ka ʻumehana, a hoʻōki ka ʻōpala.
I loko o kahi ʻūhā, i ka manawa like ka hana o ʻelua hana i ka 3-way magnet valve (IDT, vacuum heat sealing, thermal in situ.
ʻO ka mīkini meaʻai vacuum sealing ka hana nui o ka oxygen, he mea pono ia e pale i ka pōʻino o ka meaʻai, maʻalahi kāna kumu, no ka mea, ʻo ka metamorphism meaʻai e hoʻoulu ai i ka mold ma muli o ka hana o ka microorganism, a me ka hapa nui o nā microorganisms (
E like me ka mold a me ka hū)
Pono ke ola i ka oxygen, a me ka hoʻohana ʻana i kēia kumumanaʻo, ʻo ka ʻeke a me ka meaʻai i loko o ka uahi oxygen cell, nalowale ke ola microbial.
Hōʻike nā hopena hoʻokolohua: i ka wā e hoʻonui ai ka oxygen i loko o ka pahu & le;
1%, ka ulu ʻana o ka microbial a me ka nui o ka hānau ʻana i hāʻule nui loa, ka ʻike oxygen & le;
0.
5%, ʻo ka hapa nui o nā microbes e hoʻopaʻa ʻia a hoʻōki i ka hānau ʻana.
(
'Ōlelo Aʻo: hiki ke hoʻopaʻa ʻia i ka vacuum packing hiki ke pale i ka hoʻoulu ʻana o nā bacteria anaerobic a me ka hopena enzyme i hoʻokumu ʻia e ka metamorphism meaʻai a me ka discoloration, no laila pono e hui pū me nā ʻano kōkua ʻē aʻe, e like me ka mālama anu, maloʻo, dehydrated, sterilization wela kiʻekiʻe, sterilization irradiation, microwave sterilization, salting, a laila.)
