Kufikira kutentha kotheka kutentha uchi: malangizo ndi ndondomeko. Kodi n'zotheka kutentha uchi ndi kutaya katundu wake?

Uchi ndi mankhwala omwe amapangidwa ndi njuchi za maluwa. Thupili limakhala ndi mankhwala olemera kwambiri. Njuchi za uchi 95% zimakhala ndi chakudya, zomwe zimakhala bwino kwambiri ndi thupi, popanda kuwononga ndalama.

Chomeracho chiri ndi chiwerengero chachikulu cha amino acid zofunika, ma microelements ndi mavitamini kwa thupi la munthu. Mitengo yamtengo wapatali ndi yomwe idapangidwa kuchokera ku zitsamba. Lero tiyesa kudziwa momwe kutentha kuli kotheka kutentha uchi.

Zofunikira za uchi

Mwina, palibe munthu wotero amene sakanamva za mankhwala ndi zakudya za uchi. Chogwiritsiridwa ntchitochi sichinagwiritsidwe ntchito kokha kwa chakudya. Anthu adziphunziranso kuti apange njira zabwino zothandizira tsitsi ndi khungu. Chopangidwa ndipadera cha mankhwala a njuchi chimakupatsani inu kuchiza matenda ambiri. Mankhwalawa amagwiritsidwa ntchito polimbana ndi kutupa, kupweteka kwa thupi, kulimbikitsa chitetezo chokwanira, kusintha khalidwe la magazi, kupititsa patsogolo ntchito.

Pali mitundu yambiri ya maphikidwe omwe amagwiritsa ntchito uchi mukutentha komanso kusungunuka. Ndizomveka kuti ambiri a ife tikufunsa mafunso: kodi ndizotheka kutentha uchi komanso ngati zimataya katundu wabwino?

N'chifukwa chiyani mumatentha uchi?

Nthawi zambiri njuchi yotentha imagwiritsidwa ntchito popanga zodzoladzola. Madzi uchi amatha kusakanikirana ndi zinthu zina ndipo amagwiritsidwa ntchito bwino khungu ndi tsitsi. Akatswiri amavomereza kuti chipangizo chopangidwa ndi mankhwalawa sichiphatikizidwa ndi zigawo zina za chiyambi. Zina zotsalazo zimakhala zovuta ndipo zingakhoze kuvulaza khungu.

Mankhwala ochiritsira, omwe ali ochuluka kwambiri mankhwala ochiritsira, amathandizanso kugwiritsa ntchito uchi mu mawonekedwe ofunda. Chinthu china pamene timadzi timene timasungunuka timayisungira m'makina kuti tipeze zosungirako. Choncho, funso lomwe lingathe kutenthetsa uchi ndi lofunika kwambiri.

Chikoka cha mankhwala otentha pamtundu wa uchi

Tsopano tiyeni tiyese kupeza zomwe zimachitika ku chinthu chamtengo wapatali mukakwiya. Pali lingaliro lakuti uchi sungasungunuke ndi kutentha kwambiri.

Kutentha ndi + 40 ˚C. Uchi, pokhala utafika pamtundu wotere, pang'ono, umatayika zakudya zake ndi machiritso ake. Ngati mankhwalawa atenthedwa pamwamba +40 ˚C, madzi okoma okhawo amachokera ku zinthu zothandiza. Madzi adzakhala ndi shuga ndi fructose wambiri, koma osati. Kuwonjezera apo, uchi udzasanduka mdima kuposa momwe unaliri poyamba, komanso udzataya fungo lake losasangalatsa. Mtengo wa timadzi tokoma umakhala woipa kwambiri mofulumira komanso motalika umakhala wotentha.

Kutentha ndi +45 ˚C. Kuyambira ndi chizindikirochi, maonekedwe a uchi amasintha nthawi yomweyo. Chogulitsidwacho chimataya zakudya ndi mphamvu zake, pali kuwonongeka kofulumira kwa michere. Izi ziyenera kukumbukiridwa kwa omwe amakonda kuwonjezera uchi ku mkaka wotentha kapena tiyi. Akatswiri amalimbikitsa kugwiritsa ntchito kukoma kokhala ndi zakumwa.

Katemera wa khansa wa uchi

Kutentha ndi 60 ° C. Zotsatira za Kutentha pa uchi pa nthawiyi ndizovuta kwambiri. Akatswiri ena amanena kuti mankhwalawa ndi okwana +60 ˚C ndi apamwamba omwe ali ndi khansa. Kuchuluka kwa oxymethylfurfural kumapangidwa kuchokera ku saccharides, yomwe ndi mankhwala oopsa. Ndilo ndondomeko ya zinthu izi zomwe zimapanga malo okhala ndi njuchi.

Ngati udya uchi wotero, ukhoza kupha poizoni. Kugwiritsira ntchito mankhwalawa nthawi yayitali ngakhale pang'onozing'ono kungayambitse mapangidwe ndi chitukuko. Choncho, funso loyenerera la uchi wophika limatuluka kwathunthu. Akatswiri amalangiza kuti agwiritse ntchito ndi kusunga uchi mmalo mwake, popanda Kutentha popanda chofunikira chapadera.

Asayansi pa chithandizo cha kutentha kwa uchi

Mikangano pa funso la kutentha kumene uchi ungakhoze kuyaka silingagwirizane ndi masayansi. Malinga ndi ochita kafukufuku ena, uchi sungathe kutentha pamwamba pa +20 ° C. Pa kutentha kwa +3 ˚C, kutayika kwa mavitamini kumachitika. Pa +50 ˚C uchi umataya mabakiteriya ake komanso fungo lapadera, akatswiri amati.

Kutentha kwa +60 ° C kumayambitsa michere. Pa ola 80 ˚C, malinga ndi akatswiri, uchi ukuwonongedwa mu shuga ndi oxymethylfurfural amapangidwa. Kutentha kwa nthawi yaitali kwa njuchi, asayansi amakhulupirira, kumayambitsa kuthetsa kwathunthu kwa mankhwala osokoneza bongo. Kusintha kosayenera koteroko kumakhala kwa uchi pamene ukakwiya. Uchi ndi njuchi ndi chimodzi mwa nkhani zomwe zimayenera kuphunzira mosamalitsa.

Malangizo ndi malangizo pa Kutentha kwa uchi

Tsopano tikudziwa ngati n'zotheka kutentha uchi komanso kutentha kotani. Tsopano ganizirani njira zomwe mungagwiritsire ntchito pa izi.

Mavuniki a microwave. Amayamwa uchi ndi chipangizo chotchuka cha magetsi mosavuta komanso mofulumira. Komabe, ndi bwino kukumbukira kutentha komwe kuli kotheka kutentha uchi. Zoopsa, monga tikudziwira kale, chizindikiro ndi +40 ˚C. Powotcha mchere wa machiritso mu uvuni wa microwave, mumayesa kuwonongera mankhwala onsewa. Zidzatha kutentha ndipo sizidzasintha komanso zimakhala zosakaniza za shuga ndi fructose. Ngati mudasankha njira iyi, ndiye kuti uchi wosungunuka uyenera kukhala mu "Defrost" modelo, kuyambira pa masekondi 30. Pitirizani kutenga nthawi yambiri, koma mankhwalawo sadzatayika mavitamini othandiza. Nthawi yotentha imayenera kukhala masekondi 15-30, pamene uchi uyenera kukhala wolimba kwambiri. Chitani zododometsa mpaka chinthucho chimakhala chamadzi. Tsopano tikudziwa kuti kutentha kotheka kutentha uchi mu uvuni wa microwave.

Kusamba kwa madzi. Kodi ndikutentha kotani komwe uchi ungapangidwe pogwiritsa ntchito njirayi? Tsopano ife tizilingalira izo. Dziwani kuti njirayi imatengedwa kuti ndi yabwino kwambiri pakutentha kwa uchi. Sizowoneka mophweka, komanso zimakhala zotetezedwa kuti zikhale zokolola njuchi. Ndikofunika kutenga chidebe chachikulu ndikuchidzaza ndi madzi. Ikani nsalu pansi. Mu chidebe choika chotengera ndi uchi. Iyenera kukhala yokutidwa ndi madzi ndi 1/3. Tsopano yikani chidebe pamphepete ndi kubweretsa madzi kutentha kwa +40 ˚C. Kenaka ikani uvuni pazomwe mumapanga ndipo nthawi zonse muwononge mankhwalawo. Umu ndi momwe maofesi a uniform, otentha komanso otetezeka a uchi amapezeka. Oweta amalangiza kuti azigwiritsa ntchito zipangizo zotentha zowonjezera panthawiyi. Idzakuthandizani kuti muyambe kuyendetsa mlingo wa Kutentha.

Kutenthedwa ndi batri. Njira iyi ndi yabwino kwambiri. Mtsuko wa uchi umayenera kuikidwa kuchokera ku batri yotentha pamtunda wa masentimita 10 mpaka 40. Njirayi ndi yochepetsetsa, koma imathandiza kusunga makhalidwe abwino a mankhwalawa.

Choncho, tsopano tikudziwa ngati n'zotheka kutentha uchi. Malangizo ndi zidule zidzakuthandizani kupewa zolakwa zambiri.

Zosungirako zosungirako zokhudzana ndi uchi

Tsopano kuti tidziwe ngati n'zotheka kutenthetsa uchi ndi zomwe zimachitika pa nkhaniyi, m'pofunika kudziwa kuti ndi mankhwala ati omwe ayenera kusungidwa kuti asataya katundu wake. Pofuna kusungira uchi nthawi yaitali, ndi bwino kusankha matabwa, ceramic, enameled, container zamagalasi kapena chidebe chopangidwa ndi pulasitiki. Zakudya ndizofunikira kusankha opaque, mdima. Mabanki ayenera kutsekedwa mwamphamvu ndi pulasitiki kapena chivindikiro chachitsulo, chimene sichilola mpweya ndi chinyezi kudutsa.

Tiyenera kukumbukira kuti mankhwalawa amatenga zonse zotentha kunja. Mitsuko musanayambe ntchito muyenera kutsukidwa ndi madzi ndi kuwonjezera kwa soda, zouma ndi mpweya wokwanira. Nthawi yayitali kwambiri yosunga uchi sungakhoze, chifukwa patapita nthawi, imataya zinthu zonse zothandiza.

Mungasunge bwanji uchi?

Akatswiri amakhulupirira kuti ndi bwino kupewa kusunga uchi pamalo otentha komanso makamaka dzuwa. Mtengo woyenerera umatengedwa kuti ndikutentha kutentha kuchokera ku +14 ˚C mpaka +28 ˚C. Kapangidwe ka uchi sikhudzidwa kokha ndipamwamba, komanso ndi kutsika kochepa. Powonongeka ndi chimfine, mankhwalawa amayamba kuchepa ndi kutaya katundu wake. Choncho, kusunga uchi mufiriji ndi kulakwitsa kwakukulu. Ngati mutatsatira zotsatirazi, wokondedwa akhoza kusungidwa kwa zaka zitatu, osadandaula kuti adzataya makhalidwe ake.
