Izinhlobo zabaMvubelo Nendlela Abasebenza ngayo
Abagcobi basebenzisa izinto ezibhaka ukuthuthukisa ukuthungwa nokubukeka okubonakalayo. Bakha amapokhethi emoyeni ngaphakathi kwenhlama noma batsha ukuze banikeze umkhiqizo wokugcina ukukhanya okukhanyayo, ukuhlunga. Ngokuvamile, abacebi bangahlukaniswa ngezigaba ezintathu: ngokomzimba, ephilayo noma emakhemikhali.
I-carbon dioxide gas ngokuvamile ibhekene nesenzo esilisayo emithini ebhakwayo futhi ingenziwa yizinhlaka eziphilayo ezifana nemvubelo, noma ama-chemical agents njenge-baking soda ne-baking powder.
Izidumbu Zenyama
Kunezinhlobo ezimbili zemvubelo yemvelo: umoya nomoya. Uvame ukufakwa emoyeni emabhodini lapho ibhotela noshukela behlelwa ndawonye. Khipha ubisi obomvu (noma amanye amafutha aqinile) ngoshukela ubopha izibhamu ezincane ngaphakathi kwamanoni. I-air ingasetshenziselwa njengomvubelo lapho ishaya amaqanda amhlophe noma ukhilimu. Kuzo zombili izimo, umoya uboshelwe ngaphakathi kweprotheni yamatrikhi ukhilimu noma amaqanda abamhlophe, okwenza ukwanda. Ngesilinganiso esincane, ukuhlunga ufulawa futhi ugibe umoya omncane futhi ungahlinzeka ngezinga eliphansi lezenzo ezimvubelo.
Imvubelo yesibili yomzimba iyisithambile. Lapho amanzi eguqula isitshalo, ivolumu ikhula cishe izikhathi ezingu-1 600 ubukhulu bayo bokuqala. Uma ama-batters enomanzi aziswa ngamazinga aphezulu okushisa, i-liquid in the batter ngokushesha iguqula ibe umusi. I-steam iboshelwe ngaphakathi kwe-batter, okuyinto eqinisa njengoba ibhaka. I-steam isetshenziselwa imvubelo ekudleni okunjengokuthi ama- popovers , ama- cream , ama-crus crusts.
I-Biological Leaveners
Imvubelo iyisivuli sezinto eziphilayo. Imvubelo yizinto eziphilayo ezivutha ushukela wegesi kanye ne-carbon dioxide gas yi-product yale nqubo yokuvutshelwa. Ukuze uqale inqubo yokuvutshelwa, imvubelo idinga ama-carbohydrates kanye nomswakama. Ukufudumala ukusheshisa kule mpendulo, nakuba kusencane kakhulu.
Ngenxa yokuthi imvubelo ikhiqiza i-carbon dioxide ngesilinganiso esincane, ngokuvamile isetshenziselwa isinkwa esinomthamo we-gluten oqinile ongabamba igesi isikhathi eside. Ama-batter we-liquid, afana nalawo asetshenziselwa ama-pancake, ahluleka ukugcina igesi eboshelwe isikhathi eside futhi badinga imvubelo esebenza ngokusheshayo njengokwenza i-baking soda.
Amakhemikhali e-Chemical
Abafisi ababili bezimakhemikhali bakhukela i- soda ne-baking powder. I-baking soda yi-powder yemvelo e-alkaline eyenza i-carbon dioxide gas uma ihlanganiswa ne-asidi. Ngenxa yokuthi ukusabela kwenzeka ngokushesha, i-baking soda iyinhlawulo ehlekayo yezinja ezilula noma ezibuthakathaka njengama-pancake, ama-muffins, nezinye izinkwa ezisheshayo. I-buttermilk, uviniga, i-yogurt, noma ngisho ne-cocoa powder ingasetshenziswa njenge-acid kule mpendulo.
I-powder yokubhaka ifana ne-baking soda kodwa isivele iqukethe i-asidi edingekayo ukuze isabele. I-asidi e-baking powder iyindlela yosawoti, okusho ukuthi ngeke isabele kuze kuhlanganiswe namanzi. I-powder yokubhaka i-leavener enhle kakhulu yokupheka okungenayo nezinye izithako eziningi ezinama-acidic, njengekhukhi. Ama-powders amaningi e-baking athengiswa ngamabhizinisi namuhla asebenza ngokuphindwe kabili, okusho ukuthi uzokhiqiza igesi kabili-kanye uma amanzi ehlanganiswa futhi futhi lapho ingxube ibhekene nokushisa.
I-powder kabing e-baking ehlinzeka kabili inikeza isenzo esilungile nesinokwethenjelwa.
