Es Isitashi ihambisana nokudla okuyisidingo esiyisisekelo ekudleni kwabo bonke abantu, amandla amaningi esiwathola kule ngxenye futhi singawathola noma kuphi emhlabeni. Ngoba kubalulekile ukwazi, sikulethela lonke ulwazi mayelana nesitashi.
Yini isitashi?
El Isitashi iyingxenye yeqembu lama-polysaccharides, okusho ukuthi iyingxenye eyenziwe ngama-molecule amakhulu (i-polymer), ikhonza ukugcina amandla angadluliswa kuye ngokusetshenziswa kwawo, kulokhu kungaba ngokudla. Zibuye zifaneleke njengama-carbohydrate, okusho ukuthi zenziwe nge-hydrogen (H), i-carbon (C), ne-oxygen (O).
I-Los isitashi zitholakala ikakhulukazi ekudleni kwemvelaphi yemifino, ngokomlando ibaluleke kakhulu ekuthuthukisweni nasekuziphendukeleni kwemvelo komuntu, ngoba ihambisana nenani elikhulu lamandla asetshenziswa umzimba womuntu.
Ngendlela yokuthi ukudla kwethu kucebile isitashi, nokho, kunenani elikhulu labantu abangakwazi lokhu, ngakho-ke kubalulekile ukuthi sonke sazi ukuthi isitashi sokuqala sinjani empilweni yethu nokuthi ingxenye enhle ye ukudla okugcinwe ekhishini lethu kuqukethe.
Iyingxenye elula kakhulu yokugaya futhi ayinzima kule nqubo, yingakho kuvamile ukuthi abagijimi, ama-acrobats noma abantu okufanele basebenzise amandla amaningi ngokomzimba emisebenzini yabo yansuku zonke, ukuba babe nokudla okusekelwe ekudleni lokho. aqukethe isitashi.
Ukwakheka
Ngamagama amakhemikhali, isitashi iketango elakhiwe ama-molecule e-glucose, okuthi ngesikhathi esifanayo ahambisane ne-polymer, konke lokhu kuhlangene nezinye izakhi ezingaziwa ukuthi ziyingxenye yezinhlamvu ngempela yini noma ziyizinhlayiya ezingcolisayo ezingena okusanhlamvu. isitashi futhi esingeke saqedwa ngesikhathi sochungechunge lokukhiqiza kanye nokucubungula ukudla.
Lapho inani lama-molecule akha i- isitashi ngokweqile, lezi buthelela ngaphansi kwethonya Iseli yezitshalo futhi izitshalo ziwusebenzisa ukuze zigcine imisoco yazo, ngale ndlela, lapho zingenawo ama-carbohydrate anele okuzondla ngokwazo, isitashi siyawanikeza.
Yakheka lapho izitshalo zithatha izinto ezingaphili ezinikezwa imvelo ukuze zikhule futhi ziphakele inqubo, izakhi ezihilelekile amanzi nesikhutha, zisicubungula ngamandla eziwathola elangeni.
Kukhona enye i-polymer efana kakhulu nesitashi futhi ibizwa nge-glycogen, umehluko ukuthi ukwakheka kwayo kwenzeka Iseli yezilwane, nokho, futhi igcwalisa umsebenzi wokugcina amandla
Isitashi asincibiliki oketshezini, kodwa siyakwazi ukumunca ngokushesha amanzi lapho kushisa futhi ikakhulukazi uma sibila, yingakho ukudla okunesitashi okuningi kuphekwa emanzini abilayo ngaphambi kokuba kuphekwe. amanzi abandayo, ingxenye ngeke ichithe noma imunce uketshezi.
Itholakala kanjani?
Kubalulekile ukuba nesitashi ekhaya ngoba sitholakala ekudleni okusobala ekudleni kwawo wonke umuntu kungakhathaliseki ukuthi ukuphi emhlabeni futhi njengoba sishilo ngaphambili, futhi aqukethe imisoco eminingi esebenza ngaphezu kwakho konke ukuhlinzeka. amandla emzimbeni.
Ukudla okunesitashi okuvame kakhulu irayisi namazambane, kodwa akuwona kuphela lokhu okuqukethe, ngoba singakuthola nokusanhlamvu okufana ne-oats nebhali. Okusanhlamvu, udali, nobhontshisi nakho kuhlanganisa isitashi ekubunjweni kwayo, ngaphezu kokunikeza imisoco eminingi emzimbeni.
Akunakwenzeka ukungazinaki zonke izinzuzo ezaziwayo ukuthi imifino inikeza kokubili ukuthuthukiswa komzimba nokuqinisa impilo, imifino kufanele ifakwe ekudleni kwabo bonke abantu kungakhathaliseki ubudala, kusukela izakhi ezithathwa yizo zonke izinhlobo zemizimba.
Kubalulekile ukuqaphela ukuthi ukudla okucutshungulwayo akunazo izingxenye eziningi zomsoco, ngoba nakuba le nqubo isiza ukudla okuningi kube nesikhathi eside seshelufu futhi kwenza ukudla okuningi kunambitheke kakhudlwana, kuningi futhi okuthi ngokwenza lezi zinguquko ekwakhekeni nasekubunjweni kwayo. , ingxenye enkulu yenhlanganisela yokudla ingcolisiwe noma imoshekile.
I-Gelatinization yesitashi
Lapho izinhlamvu zesitashi zifakwa emanzini futhi zifinyelela izinga lokushisa elingu-60º ukuya ku-70º, khona-ke inqubo yokubuyisela amanzi iqala futhi isitashi sigcina wonke umhwamuko wamanzi ongena ngamashaneli lapho isakhiwo singahlanzekile, izinga lokushisa liphezulu, bese kuba namanzi amaningi. amuncwa futhi okusanhlamvu kunwebeka kuze kube yilapho kufinyelele endaweni ephakeme kakhulu.
I-Gelatinization ibizwa ngokuthi izinga lokushisa amanzi okufanele abe nalo ukuze lo mphumela ube khona, kodwa kuzo zonke izinhlobo zezinhlamvu ezahlukene leli zinga lihlukile. Uma okusanhlamvu kufinyelela ubukhulu bawo obukhulu futhi kusalokhu kuqhutshwa ukuhwamuka, khona-ke ngeke kuhlakazeke, kodwa kungahlakazeka futhi kufakwe into enamathiselwe noma i-gelatinous.
Utility
Ukuba nesineke ukuze ulondoloze ukudla okunempilo nokunomsoco akuwona umsebenzi olula, idlanzana kuphela labantu emhlabeni elikukhathalela ngempela ukudla kwalo futhi linakekele imizimba yalo ngokwezinga elingokomzimba, ngakho-ke kubalulekile ukuthi leli phesenti lizokwanda kanye nabantu. okungenani zama ukuzivumelanisa nendlela yokuphila enempilo, enamandla futhi enenzuzo.
Uma umuntu efuna ukuqala ukwenza imikhuba yokunakekela umzimba wakhe nokuthuthukisa umzimba wakhe, into yokuqala ayicabangayo ukuzivocavoca nokudla okufanele akugcine ukuze inqubo ithele izithelo, emva kwalokho iningi liyayishiya, njengoba nje. ukuthi , ngaphandle kokuzama ngisho nokuzama ngoba bacabanga kuphela ukuthi abantu abahlukumezekile benza yonke inqubo ibukeke.
Kumele silinganisele ukuthi lokhu kuyinkinga yokwaziswa okungelona iqiniso kuphela, ngoba endabeni yokudla akukhona ukuyeka ukudla, kuwukulawula nje konke ukudla esikudlayo, sizama ukuba nempilo ikakhulukazi noma okungenani sibe nephesenti lamafutha Amukelekayo kanye nenani eliphansi le-Acceptable Fat. amakhalori.
El isitashi Kuyingxenye ebalulekile uma kuziwa ekudleni, futhi sibhekisela ohlotsheni oluthile lokudla, njengoba sesishilo ngenhla ukuthi isitashi Itholakala ezintweni ezidliwayo ezijwayelekile ukuthi zidliwe abantu, ngaphezu kokuba nempilo kakhulu.
Ukuchezuka kancane ekudleni uqobo, i isitashi Ibhekwa njengesinye sezakhi eziyinsada kakhulu emhlabeni, njengoba ingxenye enkulu yezitshalo nemifino iwulondoloza ukuze ube nemisoco eyanele ezondla lapho lezi ziyindlala ngendlela yazo evamile.
Iqiniso liwukuthi ukuba usizo kwesitashi kudlula ukusetshenziswa nje kokudla okuhlukahlukene, okunye ukusetshenziswa kungaba ekukhiqizeni ukudla, kodwa kulokhu njengento yangaphandle yokuguqula ukwakheka nokwakheka kokunye ukudla, hhayi njengokudla okugayiwe.
Ngaphambili yayibuye isetshenziswe embonini yendwangu, ukunamathela kwendwangu futhi inikeze ukuqina kwezingubo, umphumela wokugcina uncike ohlotsheni lwengubo okufanele isetshenziswe, inganikeza ivolumu engutsheni noma ivimbele ukushwabana kakhulu futhi izolingana imiphetho uma uyisebenzisa. Ngemva kwezinye izinqubo zokuyithola, ingase isetshenziselwe ezinye izinjongo zezimboni ezengeziwe, ezifana neglue noma non-stick.
Singanquma ukuthi insiza eyinhloko yesitashi ukuzivumelanisa nezimo Izici zezinto eziphilayo ukufaka isandla ekudleni kwabo, kusukela ekugcineni kodwa okungenani, sinakho lokho ngenxa yenani eliphezulu lezakhi kanye nezingxenye ezinikeza amandla, amangqamuzana nawo ayisebenzisela inqubo yawo yokudla futhi ayadingeka ukuze aqhubeke nokuzala nokuthuthukisa.
