Kuphika nyama mpaka kufika pamlingo woyenera ndi luso lomwe limafunikira kulondola, ukatswiri, ndi zida zoyenera. Pazida izi, choyezera kutentha kwa nyama chimadziwika ngati chida chofunikira kwa wophika kapena wophika aliyense. Kugwiritsiridwa ntchito kwa thermometer sikungotsimikizira kuti nyamayo ndi yotetezeka kuti idye pofika kutentha kwamkati koyenera, komanso imatsimikiziranso maonekedwe ndi kukoma komwe kumafuna. Nkhaniyi ikufotokoza mfundo zasayansi zomwe zimatengera ma thermometers a nyama, mitundu yawo, kagwiritsidwe ntchito kake, komanso zovomerezeka zomwe zimathandizira kugwira ntchito kwawo.

Kumvetsetsa Sayansi ya Ma Thermometers a Nyama

Choyezera thermometer cha nyama chimayesa kutentha kwa mkati mwa nyama, chomwe ndi chizindikiro chofunikira kwambiri cha kudzipereka kwake. Mfundo kumbuyo kwa chida ichi ndi thermodynamics ndi kutentha kutengerapo. Pophika nyama, kutentha kumayenda kuchokera pamwamba kupita pakati, kuphika zigawo zakunja poyamba. Pakafika pakati pa kutentha komwe kukufunika, zigawo zakunja zitha kukhala zitapsa ngati sizikuyang'aniridwa bwino. Thermometer imapereka kuwerengera molondola kwa kutentha kwa mkati, kulola kuwongolera bwino kuphika.

Chitetezo cha kudya nyama chikugwirizana mwachindunji ndi kutentha kwake kwamkati. Malingana ndi USDA, mitundu yosiyanasiyana ya nyama imafuna kutentha kwapadera kwa mkati kuti athetse mabakiteriya owopsa monga Salmonella, E. coli, ndi Listeria. Mwachitsanzo, nkhuku ziyenera kutentha mkati mwa 165°F (73.9°C), pamene nyama ya ng’ombe, nkhumba, nkhosa, ndi nyama yamwana wang’ombe, chops, ndi zowotcha ziyenera kuphikidwa pafupifupi 145°F (62.8°C) ndi kutentha nthawi yopuma mphindi zitatu .

Mitundu ya Ma Thermometers a Nyama

Ma thermometers a nyama amabwera m'mitundu yosiyanasiyana, iliyonse yogwirizana ndi njira zophikira komanso zomwe amakonda. Kumvetsetsa kusiyanitsa pakati pa ma thermometers awa kungakuthandizeni kusankha yoyenera kwambiri pazosowa zanu.

• Digital Instant-Read Thermometers:

Mawonekedwe:Perekani zowerengera zachangu komanso zolondola, nthawi zambiri mkati mwa masekondi.
Zabwino Kwambiri Kwa:Kuwona kutentha kwa nyama pamagawo osiyanasiyana akuphika osasiya thermometer mu nyama.

• Dial Oven-Safe Thermometers:

Mawonekedwe:Ikhoza kusiyidwa mu nyama pamene ikuphika, kupereka kutentha kosalekeza.
Zabwino Kwambiri Kwa:Kuwotcha mabala akuluakulu a nyama mu uvuni kapena pa grill.

• Thermocouple Thermometers:

Mawonekedwe:Zolondola kwambiri komanso zachangu, zomwe nthawi zambiri zimagwiritsidwa ntchito ndi akatswiri ophika.
Zabwino Kwambiri Kwa:Kuphika mwatsatanetsatane komwe kutentha kumakhala kofunikira, monga m'makhitchini odziwa ntchito.

• Ma thermometers a Bluetooth ndi opanda zingwe:

Mawonekedwe:Lolani kuyang'anitsitsa kutentha kwa nyama kudzera pa mapulogalamu a smartphone.
Zabwino Kwambiri Kwa:Ophika otanganidwa omwe amafunika kuchita zambiri kapena amakonda kuyang'anira kuphika ali patali.

Momwe Mungagwiritsire Ntchito Thermometer Ya Nyama Molondola

Kugwiritsa ntchito thermometer ya nyama moyenera ndikofunikira kuti muwerenge zolondola ndikuwonetsetsa kuti nyama yaphikidwa bwino. Nawa malangizo ena:

• Kuwongolera:

Musanagwiritse ntchito thermometer, onetsetsani kuti yasinthidwa bwino. Ma thermometers ambiri a digito ali ndi ntchito yofananira, ndipo zitsanzo za analogi zimatha kufufuzidwa pogwiritsa ntchito njira ya madzi oundana (32 ° F kapena 0 ° C) ndi njira ya madzi otentha (212 ° F kapena 100 ° C pamtunda wa nyanja).

• Kuyika Moyenera:

Ikani thermometer mu gawo lokhuthala kwambiri la nyama, kutali ndi fupa, mafuta, kapena gristle, chifukwa izi zimatha kuwerengera molakwika. Kwa mabala owonda, ikani choyezera kutentha kuchokera kumbali kuti muyese molondola.

• Kuwona Kutentha:

Kuti muchepetse nyama zazikulu, yang'anani kutentha m'malo angapo kuti muwonetsetse kuti ikuphika. Lolani choyezera kutentha chikhazikike musanawerenge kutentha, makamaka kwa zitsanzo za analogi.

• Nthawi Yopuma:

Mukachotsa nyama ku gwero la kutentha, lolani kuti ipume kwa mphindi zingapo. Kutentha kwamkati kudzapitirira kukwera pang'ono (kuphika carryover), ndipo timadziti tidzagawiranso, kupititsa patsogolo kukoma kwa nyama ndi juiciness.

Deta ndi Ulamuliro Wothandizira Kugwiritsa Ntchito Thermometer ya Nyama

Kuchita bwino kwa ma thermometers a nyama kumathandizidwa ndi kafukufuku wambiri ndi malingaliro ochokera ku mabungwe ovomerezeka monga USDA ndi CDC. Malinga ndi USDA Food Safety and Inspection Service, kugwiritsa ntchito bwino zoyezera kutentha kwa nyama kumachepetsa kwambiri chiopsezo cha matenda obwera chifukwa cha zakudya poonetsetsa kuti nyama ifika kutentha bwino. Kuphatikiza apo, kafukufuku wasonyeza kuti zowonera, monga mtundu ndi kapangidwe kake, ndizizindikiro zosadalirika za kudzipereka, zomwe zimalimbitsa kufunikira kwa zida zoyezera kutentha kuti athe kuyeza molondola kutentha.

Mwachitsanzo, kafukufuku yemwe adasindikizidwa mu Journal of Food Protection adawonetsa kuti kugwiritsa ntchito thermometer kumachepetsa kupezeka kwa nkhuku zosaphika, zomwe ndizomwe zimayambitsa matenda a Salmonella. Kuphatikiza apo, kafukufuku wa CDC adawonetsa kuti 20% yokha ya anthu aku America omwe amagwiritsa ntchito thermometer ya chakudya nthawi zonse pophika nyama, ndikugogomezera kufunikira kwa chidziwitso komanso maphunziro okhudzana ndi chitetezo cha chakudya ichi.

Pomaliza, thermometer ya nyama ndi chida chofunikira kwambiri kukhitchini, kupereka mwatsatanetsatane kofunikira kuti nyama yophikidwa bwino nthawi zonse. Pomvetsetsa mitundu ya ma thermometers omwe alipo, kagwiritsidwe ntchito kake moyenera, ndi mfundo zasayansi zomwe zimawatsogolera, ophika amatha kuonetsetsa kuti nyama yawo ndi yotetezeka komanso yokoma. Deta yovomerezeka ikugogomezera kufunika kwa chida ichi popewa matenda obwera chifukwa cha zakudya komanso kupititsa patsogolo zotsatira zazakudya. Kuyika mu thermometer yodalirika ya nyama ndi gawo laling'ono lomwe limapangitsa kusiyana kwakukulu muzophika, zopatsa mtendere wamaganizo ndi zophikira zabwino.

Kuti mumve zambiri za malangizo ndi malingaliro, pitani ku USDA'sChitetezo Chakudya ndi Ntchito Yoyang'anirandi ma CDCChitetezo Chakudyamasamba.
