Nano-zinc oxide ndi chinthu chatsopano chosapangidwa ndi zinthu zachilengedwe chomwe chili ndi ntchito zosiyanasiyana zomwe zinc oxide wamba sangagwirizane nazo. Chimaonetsa makhalidwe odalira kukula monga zotsatira za pamwamba, zotsatira za voliyumu, ndi zotsatira za kukula kwa quantum.

Ubwino Waukulu WowonjezeraNano-Zinc OxideKudyetsa:

1. Kuchuluka kwa Bioactivity: Chifukwa cha kukula kwake kochepa, tinthu ta nano-ZnO timatha kulowa m'mipata ya minofu ndi m'mitsempha yaying'ono kwambiri, ndikufalikira kwambiri m'thupi. Izi zimapangitsa kuti zakudya zosakaniza zikhale ndi bioavailability yambiri, zomwe zimapangitsa kuti zikhale zogwira ntchito kwambiri kuposa zinthu zina zomwe zimapezeka m'thupi.
2. Kuchuluka kwa Kuyamwa kwa Tinthu Tating'onoting'ono: Kukula kwa tinthu tating'onoting'ono kwambiri kumawonjezera chiwerengero cha maatomu pamwamba, zomwe zimapangitsa kuti malo omwe ali pamwambawo azioneka bwino komanso kumawonjezera kuyamwa kwa tinthu tating'onoting'ono. Mwachitsanzo, kafukufuku pa mbewa za De-sai adawonetsa kuti tinthu tating'onoting'ono ta 100 nm tinali ndi kuchuluka kwa kuyamwa kwa tinthu tating'onoting'ono tokhala ndi mayamwidwe okwana 10-250 kuposa tinthu tating'onoting'ono tating'onoting'ono.
3. Mphamvu Zamphamvu Zoletsa Kutupa: Nano-ZnOImakhala ndi mphamvu zambiri zamagetsi, zomwe zimathandiza kuti ipangitse kuti zinthu zachilengedwe ziwonongeke, kuphatikizapo zigawo za mabakiteriya, motero imapha mabakiteriya ndi mavairasi ambiri. Pansi pa kuwala, imapanga ma electron a conduction-band ndi mabowo a valence-band, omwe amachita ndi H₂O kapena OH⁻ yotsekedwa kuti ipange ma hydroxyl radicals oxidative kwambiri omwe amawononga maselo. Mayeso adawonetsa kuti pa 1%, nano-ZnO idapeza 98.86% ndi 99.93% ya mabakiteriya opha tizilombo motsutsana ndiStaphylococcus aureusndiE. colimkati mwa mphindi 5, motsatana.
4. Chitetezo Chapamwamba: Sichimayambitsa kukana kwa ziweto ndipo chimatha kuyamwa ma mycotoxins omwe amapangidwa panthawi ya kuwonongeka kwa chakudya, zomwe zimateteza matenda omwe nyama zimadya chakudya chokhala ndi bowa.
5. Kuwongolera Chitetezo cha Mthupi: Kumalimbikitsa kwambiri ntchito za maselo, zachiwerewere, komanso zosakhudzana ndi chitetezo chamthupi, zomwe zimapangitsa kuti nyama zisadwale matenda.
6. Kuchepetsa Kuipitsidwa kwa Zachilengedwe ndi Zotsalira za Mankhwala Ophera Tizilombo: Malo ake akuluakulu amalola kuti ammonia, sulfur dioxide, methane, mankhwala ophera tizilombo a organophosphorus, ndi zinthu zina zoipitsa chilengedwe zilowe m'madzi otayidwa. Ingagwiritsenso ntchito kuwala kwa UV powononga mpweya, kuyeretsa mpweya ndi madzi otayidwa m'mafamu mwa kuwola fungo.

Udindo wa Nano-ZnO pakukweza thanzi la ziweto ndi kukula kwake:

• Kumalimbikitsa ndi Kulamulira Kagayidwe kachakudya: Kumawonjezera ntchito ya ma enzyme odalira zinc, kutulutsa mahomoni (monga insulin, mahomoni ogonana), ndi kupanga mapuloteni a zinc chala, kukonza kapangidwe ka mapuloteni ndi kugwiritsa ntchito bwino nayitrogeni pamene kumachepetsa kutulutsa nayitrogeni.
• Kumawonjezera Kuchita Bwino kwa Nkhumba: Mu ana a nkhumba, kuwonjezera 300 mg/kg nano-ZnO kunawonjezera kwambiri kulemera kwa tsiku ndi tsiku (P < 0.05) ndi 12% poyerekeza ndi ZnO yachizolowezi (3000 mg/kg) ndi kuchepetsa chiŵerengero cha kusintha kwa chakudya ndi 12.68%.
• Amachepetsa Kutsegula M'mimba:Kuonjezera Nano-ZnO mu chakudya cha ana a nkhumba kumachepetsa kutsegula m'mimba, kupewa zotsalira za maantibayotiki mu zakudya za ziweto.

Ubwino Womwe Ungakhalepo pa Zachilengedwe:

• Kuchepa kwa Utsi wa Zinc: Chifukwa cha kugwiritsidwa ntchito bwino kwambiri, mlingo wochepa umafunika, zomwe zimachepetsa kwambiri kuipitsa kwa zitsulo zolemera.
• Kuyeretsa Malo Olima: Kumachotsa mpweya woipa (monga ammonia) ndi kuwononga zinthu zachilengedwe m'madzi otayidwa, kuteteza malo ozungulira.

Kugwiritsa Ntchito Pakali pano Pakupanga Chakudya cha Zinyama:

• Njira Zosiyanasiyana Zogwiritsira Ntchito: Zingawonjezedwe mwachindunji ku chakudya, kusakaniza ndi zosakaniza ngati zosakaniza, kapena kuphatikiza ndi zowonjezera zina. Mlingo wocheperako wogwira ntchito ndi 10 mg Zn/kg chakudya. Mu ana a nkhumba, mlingo umayambira pa 10–300 mg Zn/kg chakudya.
• Kusintha pang'ono kwa Zinc Yachikhalidwe: Nano-ZnO ikhoza kulowa m'malo mwa zinc wambiri mu chakudya, kuchepetsa kutsegula m'mimba kwa ana a nkhumba pamene ikukweza kukula bwino poyerekeza ndi zinc wamba (monga zinc sulfate, wamba ZnO).
• 

Ziyembekezo Zamtsogolo Pakupanga Chakudya cha Ziweto:

• Kukhazikika ndi Mtengo Ubwino: Kuyenda bwino komanso kufalikira bwino kumathandiza kusakaniza chakudya mofanana. Mlingo wochepa wofunikira umachepetsa ndalama zogulira chakudya (monga, kuchepera 10 kuposa ZnO yachizolowezi).
• Kusunga ndi Kuchotsa Poizoni: Kumwa kwambiri kwa ma free radicals ndi mamolekyulu onunkhira kumawonjezera nthawi yogwiritsira ntchito chakudya ndipo kumawonjezera kukoma. Mphamvu zake zotsutsana ndi ma antioxidants zimathandiza kuchotsa poizoni m'thupi.
• Zotsatira Zogwirizana pa Zakudya: Zimachepetsa kusamvana ndi mchere wina ndipo zimathandizira kuyamwa kwa nayitrogeni kudzera mu mahomoni ndi mapuloteni a zinc chala.
• Chitetezo Chabwino: Kuchepa kwa kutulutsa zinthu kumachepetsa kuipitsidwa kwa chilengedwe ndi kusonkhanitsa zinyalala, zomwe zimathandiza kupanga nyama zotetezeka komanso zobiriwira.

Ukadaulo uwu uli ndi lonjezo lalikulu la kupanga ziweto mokhazikika komanso moyenera.
