Ke ola nei nā huaʻai a me nā mea kanu hou ma hope o ka ʻohi ʻia ʻana, e hoʻomau ana i ka hanu a komo i nā hana ola ikaika. Ma ka ʻaoʻao hoʻokahi, hoʻopau ka hanu hanu i nā huaʻai a me nā mea kanu ponoʻī a me ka wai, e pili ana i ko lākou helehelena a me ka maikaʻi; ma ka ʻaoʻao ʻē aʻe, hiki i ka maʻi e nā microorganism pathogenic ke kumu i ka pala a me nā huaʻai. No laila, maloʻo pinepine nā huaʻai a me nā huaʻai hou, emi i ka maikaʻi, a pala i ka wā o ka mālama ʻana, ka lawe ʻana, a me ke kūʻai ʻana, pēlā e hōʻemi ai i kā lākou meaʻai.
ʻAʻole kōkua wale ka ʻōpala maikaʻi i ka mālama ʻana i nā huaʻai a me nā mea kanu hou, e hōʻemi ana i ka palaha a hoʻonui i ke ola o ka mālama ʻana, akā e hoʻohuli pū i nā mea kūʻai aku a paipai i ka hoʻohana ʻana i ka huahana. ʻO ka kiʻiʻoniʻoni plastik i kēia manawa ka mea hoʻohana pinepine ʻia no nā huaʻai a me nā mea kanu. Loaʻa iā ia nā pōmaikaʻi e like me ka transparency, insulation heat, breathability, sealing, a me ke kumu kūʻai haʻahaʻa, a loaʻa iā ia nā manaʻo noi noi mākeke. Ma lalo iho nei e hoʻolauna i nā ʻano no ka mālama ʻana i nā huaʻai a me nā mea kanu hou.
Nā ʻeke polyethylene microporous kiʻekiʻe
I nā makahiki i hala iho nei, ua hoʻohana nui ʻia kēia mea hoʻopili i waho no ka hoʻopili ʻana i nā huaʻai hou. Ma muli o nā hiʻohiʻona physiological o nā huaʻai a me ko lākou ʻae ʻana i ka oxygen a me carbon dioxide, hiki ke hoʻohui ʻia kekahi mau micropores (40μm) i ka ʻeke kiʻiʻoniʻoni e hoʻomaikaʻi i ka hoʻololi kinoea, hoʻemi i ka haʻahaʻa a me nā metabolites volatile i loko o ka ʻeke, a mālama i ka neʻe o ka oxygen i loko o ka ʻeke ma kahi kiʻekiʻe kiʻekiʻe (<1% O2). This prevents excessive oxygen concentration from causing anaerobic respiration, thereby avoiding the accumulation of large amounts of volatile substances such as ethanol and acetaldehyde, which would affect the flavor of the fruit. The oxygen concentration inside the film bag can generally be maintained at around 10-15%, and it is highly tolerant of carbon dioxide concentration, making it especially suitable for fruits and vegetables with high humidity, particularly tropical fruits. In other countries, these packaging bags are used to store "frozen" cherries, which can be preserved for 80 days in ordinary cold storage while maintaining the flavor and quality of the fruit.
-oxygen kiʻekiʻe i hoʻololi ʻia i ka ʻeke
He ʻano ʻano hou o ka hoʻopili ʻana i puka mai i nā makahiki i hala iho nei. Mālama ʻia ka maʻiʻo oxygen i loko o nā ʻeke kiʻekiʻe-oxygen self-chlorinated ma 70-100%. Loaʻa i kēia puʻupuʻu nā pōmaikaʻi penei: (1) kaohi i ka hana enzyme a pale i ka browning o nā huaʻai a me nā huahana meaʻai; (2) pale i ka hanu anaerobic a mālama i ka maikaʻi o nā huaʻai a me nā huaʻai; (3) pale pono i ka ulu aerobic a me anaerobic o nā microorganisms a pale i ka pala, a no laila ua huki nui ʻia. He kūpono loa ia no ka mālama ʻana i nā huaʻai hou a me nā mea kanu a me nā huaʻai a me nā huaʻai hou i ʻoki ʻia e pili ana i ka hanu anaerobic a me ka fermentation ma lalo o ke kiʻekiʻe carbon dioxide a me ka haʻahaʻa oxygen. I ka manawa like, hoʻoholo ʻia ka ratio hui o nā kinoea i loko o ka ʻeke e like me nā ʻano o nā huaʻai a me nā mea kanu like ʻole.
Nā mea hoʻopalapala biodegradable hou
Ma muli o ka hopohopo no ka hoʻohana lōʻihi -mea hoʻopaʻapaʻa kemika e hōʻino i ke olakino kanaka a hoʻohaumia i ke kaiapuni, hui pū me ka piʻi nui ʻana o ka makemake no ka paʻi kiʻiʻoniʻoni plastik a me ka ulu ʻana o ka pilikia o ka "pollution keʻokeʻo," ua neʻe nā pono hana o nā kānaka no nā mea paʻi lole i ka palekana, ʻaʻole -ʻona, a me ke aloha kaiapuni. ʻO nā mea hoʻopihapiha biodegradable hou he kumuhana wela hou i ka māla ʻai meaʻai honua. Hoʻohana ia i nā ʻano mea polymer biodegradable a hoʻohui i nā bactericides biological, hoʻohui i nā hana he nui e like me ka mālama ʻana, ka hoʻohaʻahaʻa a me ka pale ʻana i ke kaiapuni. He mea maʻalahi kēia mea hoʻopaʻa mea e hoʻohana, ʻoi aku ka maikaʻi no ka hōʻiliʻili ʻana i nā huaʻai a me nā meaʻai i ʻoki ʻia a me nā meaʻai i kuke ʻia, a loaʻa iā ia nā manaʻo hoʻohana ākea ma ke kahua o ka ʻeke meaʻai hou i ka wā e hiki mai ana.
