Nkhani zokhudzana ndi chitetezo chazakudya zimagwirizana ndi thanzi la aliyense, choncho nthawi zonse anthu akhala akuyang'ana kwambiri.Makamaka m'zaka zaposachedwa, chifukwa cha chuma chambiri cha anthu komanso kusintha kwa moyo kosalekeza, kufunikira kwa kuyesa kwa chakudya kukukulirakulira.

M'malo mwake, ntchito yoyesa chakudya ndi kuwunika nthawi zambiri imagawidwa m'magulu awiri: imodzi ndi ya zinthu zaukhondo, ndipo inayo ndi ya zinthu zabwino.

Komabe, ziribe kanthu kuti ndi mtundu wanji, m'pofunika kuwonetsetsa kuti zotsatira za mayeso ndizolondola, mwinamwake sizingatheke kupanga kusanthula kwina ndi kuwonetsera.Kuonjezera apo, kupatulapo zitsanzo zomwe zimayenera kuyesedwa, ngati pali vuto ndi madzi, ma reagents, kapena glassware poyang'ana chakudya mu labotale, ndiye kuti zotsatira za mayeso a chakudya zidzafunsidwa.

Zofunikira pakuwunika chitetezo cha chakudya

Kuyesa chitetezo chazakudya ndikugwiritsa ntchito malingaliro oyambira ndi njira zaukadaulo kuphatikiza fizikisi, chemistry, biology ndi machitidwe ena kuti ayang'ane, kudziwa ndi kusanthula zosakaniza zazikulu, mawonekedwe, ndi mawonekedwe a microbiological aiwisi, zida zothandizira, zomalizidwa pang'ono, zomalizidwa. , ndi zopangira.Zofunikira ndizo:

① Sonkhanitsani zitsanzo: tsimikizirani cholinga cha mayeso, pangani kuchuluka kwa mayeso ndi zinthu zina zachitsanzo.

② Kukonzekera kwa zitsanzo: Ikani zitsanzozo m'mabotolo oyera a zitsanzo, ndipo lembani mabotolo achitsanzo molingana ndi manambala a siriyo pa zitsanzozo.Zizindikiro zomwe zapangidwa ziyenera kuzindikira momwe kuyendera zitsanzo.Konzani kusanja kwachitsanzo kuti mukhazikitse ma curve a zitsanzo ndi njira yodziwira zitsanzo.

③Zitsanzo zoyesa: Mothandizidwa ndi zida zofananira, ma reagents kapena mayankho okhazikika ndi yankho la mayeso adzayesedwa nthawi imodzi.Pambuyo powerengera zotsatira za mayeso ndikupeza zolemba zoyambirira, lipoti la mayeso likhoza kulembedwa.

Pochita izi, madzi, ma reagents, ndi magalasi amagwira ntchito zosiyanasiyana.

Madzi: Madzi oyera okonzedwa mwapadera ndi madzi osungunuka ndi chinthu chofunikira kwambiri pakuwunika chakudya.Pazinthu zoyeserera, monga kukonzekera kwa reagent ndi siteji yoyesera, gwiritsani ntchito madzi wamba osungunuka ngati chisankho chachikulu.Ndizofunikira kudziwa kuti kutsimikiza kwazinthu zina zikachitika, kukhudzika kwamadzi osungunuka kumafunika kukonzedwanso kuti alowe muyeso ina yoyesa chakudya.

Ma reagents: Ma reagents omwe akuyesedwa ayenera kugwiritsidwa ntchito moyenera kuti akhudze sayansi komanso kulondola kwa zotsatira zowunika chakudya.Chisamaliro chapadera chiyenera kuperekedwa kwa alumali moyo wa mankhwala reagents.Kukhazikika ndi khalidwe liyenera kuyesedwa nthawi zonse, ndipo kugwiritsa ntchito mankhwala otha msinkhu kumaletsedwa, mwinamwake zidzakhudza kulondola kwa chidziwitso.Komanso, titrating yankho mosamalitsa malinga ndi mfundo zogwirizana akhoza kuchepetsa chiopsezo reagent kulephera.

Zagalasi: Pakalipano, mabotolo agalasi kapena zinthu za polyethylene zimagwiritsidwa ntchito makamaka poyesa zakudya zomwe zimagwiritsidwa ntchito poyesera, zomwe zingagwiritsidwe ntchito kusunga mankhwala, kunyamula mankhwala, ndi kuyesa mankhwala.Monga machubu oyesera, ma beak, ma flasks a volumetric, zoyezera ma flasks ndi ma flasks a Erlenmeyer.Koma chofunikira kwambiri ndikuwonetsetsa kuti ukhondo ndi kutayikira kwa zida zamagalasizi zikugwirizana ndi zofunikira komanso zofunikira.Choncho, chidebe cha mankhwala oyesera chiyenera kutsukidwa bwino ndi kutsukidwa musanagwiritse ntchito kuonetsetsa kuti palibe zonyansa.Ntchito ya glassware ndi pafupifupi mbali zonse zofunika kuunika chakudya.

Ndi kuipitsidwa kotsalira kotani komwe kumachitika nthawi zambiri poyesa zakudya?Kodi ikhoza kutsukidwa?

Ntchito iliyonse yoyesa kuyesa chakudya idzatulutsa zotsalira zotsalira mu magalasi, monga tizilombo tating'onoting'ono, zotsalira za mankhwala ophera tizilombo, formaldehyde, zitsulo zolemera, ma proteases, zowonjezera chakudya, zolimbitsa thupi, zotsalira za reagent pakuyesa kuyesa, Kutsuka choyambitsa panthawi yoyeretsa, ndi zina zotero. Choncho, glassware ayenera kutsukidwa pamaso ntchito lotsatira.Koma izi sizimangokhudza kuyeretsa pamanja.Poganizira kuchuluka, kusiyanasiyana, kuchepa kwa ogwira ntchito, komanso nthawi yolimba, tiyeni tiwone ubwino wamakina ochapira labuopangidwa ndi Hangzhou Xipingzhe Instruments Technology Co., Ltd ?Mwachitsanzo, kuyeretsa sikungodalirika komanso kolondola kuposa kuyeretsa pamanja, komanso kujambulidwa, kutsimikizika, komanso kubwereza!Kuphatikizidwa ndi wanzerumakina ochapira magalasikuti muwongolere ntchito yoyeretsa, ndizothandiza kwambiri pakuwongolera bwino kwa kuyesa kwa chakudya chonse komanso kutsimikizira chitetezo.

Mwachidule, kupititsa patsogolo kulondola kwa zotsatira zoyesa chakudya ndi njira yomwe makampani oyesa zakudya akupitilizabe kukwaniritsa.Kuti zotsatira zowunika zachitetezo chazakudya zigwirizane ndi zoyeserera zenizeni, chilichonse chamadzi, ma reagents, ndi magalasi ndizofunikira.Makamaka, kuyeretsa kwamakina ochapira magalasiakhoza kupititsa patsogolo ukhondo mosalekeza kuti akwaniritse miyezo yoyembekezeka ya kuyesa kwa zakudya.Ndi njira iyi yokha yomwe ingagwiritsire ntchito bwino ngati cholinga komanso maziko olondola.Ndikukhulupirira kuti oyang'anira zakudya azikumbukira izi, ndipo musalole kuti ntchito yoyang'anira chitetezo cha chakudya ikhale yochepa kapena kuwonongeka chifukwa choyeretsa magalasi.
