ʻO nā hiʻohiʻona a me nā hana o ka pahu meaʻai hau

ʻO kapuʻupuʻu mālama anua hiki i ka cryopreservation o ka meaʻai ke hoʻemi i ka hanu ʻana o nā ʻano meaʻai hou a pale i ka ulu nui ʻana a me ka ulu ʻana o nā sela meaʻai hou mai ka oʻo ʻana a me ka oʻo ʻana, ka hopena o ka pala a me ka pōʻino o ka meaʻai, nā mea kanu hou a me nā huaʻai hou;Ma ka ʻaoʻao ʻē aʻe, ʻo ka meaʻai i loko o ka refrigerated a me ka hau hau e pale aku i ka hana o nā microorganisms, ʻo ia ke kumu nui e hōʻino ai i ka meaʻai, a hoʻopuka i ka hopena hoʻomaʻemaʻe bacteria, hiki ke hoʻolōʻihi i ke ola o ka meaʻai.No laila, hoʻohana nui ʻia ke ʻano o ka mālama ʻana i nā wikiō i loko o ka pahu hau a me ka hau.

Hiki ke hoʻokaʻawale ʻia ka meaʻai paʻa paʻa i loko o ka pahu hau a me ka hoʻopili ʻana i ka friji.ʻOiai he haʻahaʻa loa ka haʻahaʻa haʻahaʻa i ka haʻahaʻa haʻahaʻa, pono e hana ʻia ka mālama ʻana i ka haʻahaʻa haʻahaʻa i loko o ka hale kūʻai, i ʻole e hoʻomaloʻo ka nui o ka wai i ka meaʻai a nalowale ka ʻono hou.ʻO ke ala maʻalahi ka uhi ʻana i ka ʻili.ʻO ka hoʻohana ʻana i ka kiʻiʻoniʻoni plastik me ka haʻahaʻa haʻahaʻa a me ka moisture permeability hiki ke pale i ka nalowale o ka wai, a maʻalahi hoʻi e hana mechanically i loko o ka pahu hau.

Waihona anu ma lalo o ka pahuHoʻohui pinepine ʻia me ka aseptic packaging, deaeration packaging, gas replacement packaging and other packaging method, hiki ke hoʻolōʻihi i ke ola lawelawe o ka meaʻai.Hiki ke koho ʻia nā mea hoʻopili paʻa hau hau.Pono lākou e loaʻa ka ikaika kaha kiʻi maikaʻi, ka ikaika o ka hopena, ka pale ʻana i ka puncture, ka ikaika hoʻopaʻa wela a me ka maʻalahi i ka haʻahaʻa haʻahaʻa, i mea e mālama ai i ka ikaika a me ka paʻakikī.

I ka haʻahaʻa wela, ka mois permeability okiʻiʻiʻoniʻonike emi nei a ke hoʻomaikaʻi nei ke kūpaʻa o ka makū.Me ka hoʻonui ʻana o ka manawa, e piʻi ka nui o ka oxygen i loko o ka ʻeke meaʻai i hoʻopaʻa ʻia, akā e emi ana ka piʻi ʻana o ka oxygen i ka haʻahaʻa haʻahaʻa.ʻOiaʻiʻo, inā ʻo ka meaʻai i hoʻopaʻa ʻia i loko o ka ʻeke ka hana o ka hanu cell, a laila e hoʻemi ʻia ka oxygen a hoʻonui ʻia ke kalapona.Ma muli o ka hanu ʻana o nā pūnaewele a hoʻopaʻa i ka oxygen a hoʻokuʻu i ke kinoea carbon dioxide, ʻoi aku ka maikaʻi o ka pale o ke kiʻiʻoniʻoni, ʻoi aku ka maʻalahi o ka hoʻokō ʻana i ke kūlana mālama cell, ʻo ia hoʻi, ke emi ka oxygen ma lalo o 2% a ʻoi aku ka nui o ka carbon dioxide. ma mua o 8%, aia nā pūnaewele i ka hibernation state, i mea e hoʻolōʻihi i ka manawa mālama.

Puke meaʻai maloʻohiki ke hoʻohana ʻia no ka mālama ʻana i ka hau o nā meaʻai e like me: yogurt, mea inu lactobacillus, cream, cheese, soy milk, fresh noodles, tofu, ham, sausage, pickled iʻa maloʻo, iʻa puhi, nā huahana wai, pickles, ʻano kuke ʻai, kuke maʻamau, hamburger, pizza maka, etc.
