He aha ke ʻano o ka hoʻopaʻa ʻana i ke kino

ʻO ka pahu pahu, ʻike ʻia ʻo ka decompression packaging, ʻo ia ka lawe ʻana i ka ea āpau i loko o ka pahu pahu a hoʻopaʻa iā ia e mālama i kahi kiʻekiʻe o ka decompression i loko o ka ʻeke. ʻO ka liʻiliʻi o ka ea ua like ia me ka hopena o ka oxygen haʻahaʻa, no laila ʻaʻohe kūlana ola o nā microorganism, i hiki ai ke loaʻa ka meaʻai hou a ʻaʻohe maʻi. kumu o ka hanana. Hoʻokomo ʻia nā noi i loko o nā ʻeke plastik, ka pahu alumini alumini, nā mea aniani, ka plastic a me kāna mea hoʻopili mea hoʻohui, a me nā mea ʻē aʻe. No ka mea he meaʻai hou ka hua, ke hoʻomau nei ka hanu, a ʻo ke kiʻekiʻe o ka hypoxia e hoʻoulu i nā maʻi physiological. No laila, liʻiliʻi ka hoʻohana ʻia ʻana o ka ʻōpala maloʻo no ka hua.

Manaʻo a me ka hana

ʻO ka puʻupuʻu vacuum kahi pūʻolo e pale ai i nā huahana mai ka haumia o ke kaiapuni a hoʻolōʻihi i ke ola o ka meaʻai, hiki ke hoʻomaikaʻi i ka waiwai a me ka maikaʻi o nā huahana. Ua hoʻokumu ʻia ka ʻenehana hoʻopili ʻana i ka vacuum i ka makahiki 1940. Mai ka hoʻohana pono ʻana o nā kiʻi ʻoniʻoni polyester a me ka polyethylene plastic i ka ʻeke kūʻai i ka makahiki 1950, ua ulu wikiwiki nā mīkini pahu pahu.

Ma ke kahua o ke ola a me ka hana o ka poʻe, hiki ke ʻike ʻia nā ʻano pahu pahu pahu plastik āpau ma nā wahi āpau. ʻO ka māmā māmā, paʻa i ka ea, mālama hou, anti-corrosion, a me anti-rust plastic vacuum packaging e uhi ana i nā māla he nui mai ka meaʻai a hiki i ka lāʻau lapaʻau, nā lole wili, mai ka hana huahana pololei a hiki i nā mea kanu metala a me nā hale hana. ʻO ka hoʻonui nui ʻana o ka hoʻohana ʻana o ka plastic vacuum packaging i hāpai i ka hoʻomohala ʻana i nā mīkini pahu pahu plastik a waiho i mua i nā koi kiʻekiʻe no lākou.

ʻO ke ʻano o ka hoʻopaʻa ʻana i ka vacuum: ʻo ke kumu e hōʻemi i ka ʻike o ka oxygen i loko o ka pōʻai, e pale i ka pala a me ka hōʻino ʻana o ka meaʻai i hoʻopili ʻia, mālama i ke kala a me ke ʻala o ka meaʻai, a hoʻolōʻihi i ke ola o ka papa.

ʻO ka hana koʻikoʻi o ka hoʻopili ʻana i ka vacuum ka wehe ʻana i ka oxygen e kōkua i ka pale ʻana i ka meaʻai mai ka pōʻino. He mea maʻalahi ka loina, no ka mea, ma muli o nā hana o nā microorganisms, ʻo ke ola ʻana o ka hapa nui o nā microorganisms (e like me ka mold a me ka hū) e pono ai ka oxygen. ʻAe, a hoʻohana ʻia ka ʻeke ʻumeke i kēia kumu no ka lawe ʻana i ka oxygen i loko o ka ʻeke ʻeke a me nā pūnaeʻa meaʻai, i lilo ai nā micro-objects i ko lākou "ola ola". Ua hōʻike ʻia nā hoʻokolohua: inā ʻo ≤1% ka nui o ka oxygen i loko o ka ʻeke ʻeke, e hāʻule nui ka ulu a me ka wikiwiki o ka hana hou ʻana o nā microorganisms, a i ka wā i ≤0.5% ka nui o nā microorganisms e pale ʻia a hoʻōki i ka hānau ʻana. (E hoʻomaopopo: ʻAʻole hiki i ka pahu pahu ke kāohi i ka ulu ʻana o ka bacteria anaerobic a me ka hōʻino ʻana o ka meaʻai a me ka discoloration ma muli o ka hopena o ka enzyme, no laila pono e hui pū ʻia me nā ʻano kōkua ʻē aʻe, e like me ka refrigeration, wikiwiki-freezing, dehydration, sterilization kiʻekiʻe, radiation sterilization, microwave sterilization, paʻakai pickled etc.)

Ma waho aʻe o ka pale ʻana i ka ulu ʻana a me ka hana hou ʻana o nā microorganisms, ʻo ka vacuum deoxygenation kekahi hana koʻikoʻi e pale aku ai i ka meaʻai. Ma muli o ka nui o nā ʻakika momona unsaturated i loko o nā meaʻai aila, ua hoʻoneʻe ʻia lākou e ka oxygen, e ʻono ai ka meaʻai a me ka pōʻino. Eia hou, ho'ohāhā 'ia ka mea'ai Ka lilo 'ana o nā huaora A a me C, nā mea pa'a 'ole i loko o ke kala mea'ai e ho'opilikia 'ia e ka oxygen, e 'ele'ele ai ke kala. No laila, hiki i ka wehe ʻana o ka oxygen ke pale pono i ka meaʻai mai ka pōʻino a mālama i kona kala, ʻala, ʻono a me ka waiwai o ka meaʻai.

ʻO ka hana koʻikoʻi o ka pahu hau piha piha i ka ea ʻaʻole wale ka hana o ka mālama ʻana i ka oxygen, akā ʻo ka hana o ka anti-pressure, ka pale ʻana i ka ea a me ka mālama hou. Hiki iā ia ke mālama pono i ke kala kumu, ka ʻala, ka ʻono, ke ʻano a me ka maikaʻi o ka meaʻai no ka manawa lōʻihi. waiwai waiwai. Eia kekahi, ʻaʻole kūpono nā meaʻai he nui no ka hoʻopili ʻana i ka ʻūhā akā pono e hoʻopiha ʻia me ka hoʻonui ʻana i ka ʻai. E like me ka meaʻai crispy a palupalu, nā meaʻai maʻalahi e hoʻohui ʻia, nā meaʻai maʻalahi e hoʻoheheʻe a nalowale ka aila, nā meaʻai me nā ʻaoʻao ʻoi a i ʻole ka paʻakikī kiʻekiʻe e kī ai i ka ʻeke ʻeke, a me nā mea ʻē aʻe. ʻeke ʻeke.

Hoʻopiha ʻia ka ʻeke piha piha i ka ea me ka nitrogen, carbon dioxide, oxygen hoʻokahi kinoea a i ʻole ka hui ʻana o ʻelua a ʻekolu mau kinoea ma hope o ka momi. ʻO ke kinoea nitrogen he kinoea inert, e hana ana ma ke ʻano he hoʻopiha e mālama i kahi kaomi maikaʻi i loko o ka ʻeke e pale ai i ka ea ma waho o ka ʻeke mai ke komo ʻana i ka ʻeke a pale i ka meaʻai. Hiki ke hoʻoheheʻe ʻia ka Nitrogen dioxide i loko o nā momona a i ʻole ka wai, a ʻo ka ʻakika carbonic māmā i lawe ʻia e kēia hoʻoheheʻe ʻana e kāohi i kekahi mau mircobia e like me ka mold a me ka putrefactive bacteria. Hiki i kona oxygen ke keʻakeʻa i ka ulu a me ka hoʻohua ʻana o nā bacteria anaerobic, mālama i nā huaʻai a me nā huaʻai hou a me ka waihoʻoluʻu, a hiki i ka ʻike nui o ka oxygen ke mālama i ka ʻiʻo hou i ʻulaʻula. ʻAʻole nalowale ka meaʻai i ka hou o nā huaʻai a me nā mea kanu.
