Baking hmoov - ib tug tseem ceeb muaj rau ci

Nyob rau hauv zus tau tej cov ntau yam confectionery thiab bakery khoom uas yuav luag ib txwm siv ib tug los yog lwm yam ci hmoov mus rau qhov kev kuaj ntawd. Ua tsaug rau nws, ci yuav ntau airy, sib zog ci los ntawm thiab muaj ib tug zoo sib xws.

Yuav ua li cas yog lub ci hmoov mus rau qhov kev kuaj no? Qhov no lub npe muaj ib yam khoom uas, thaum ntxiv rau yam khoom noj muab rau lawv splendor thiab looseness. Muaj ib tug xov tooj ntawm txawv tshuaj lom neeg thiab lom tebchaw, uas yog siv raws li xws li. Ci hmoov rau cov khob noom cookie uas nws muaj pes tsawg leeg yog yooj yim heev, koj muaj peev xwm yuav nyob rau hauv tej khw. Nws yog siv rau ci dej qab zib uas tsis muaj kev saj. Muaj ob peb hom ntawm cov tshuaj no, hu ua "baking hmoov".

Nyob rau hauv lub confectionery thiab ci muaj ntau lawm siv ib tug ntau yam ntawm tshuaj leavening agents: ammonium carbonate, lub sib tov ntawm sodium bicarbonate rau sodium carbonate, sodium bicarbonate, ammonium bicarbonate, sodium carbonate, pyrophosphate, poov tshuaj carbonate, orthophosphates, poov tshuaj bicarbonate, qab zib ntawm cov tartar (sib tov ntawm poov tshuaj bitartrate nrog tartrate poov tshuaj).

Ammonium carbonate - ci hmoov, uas yog feem ntau lug siv rau kev npaj ntau yam khoom los ntawm khob noom cookie. Qhov no tshuaj yog ib qho loj tivthaiv ntawm yuav luag tag nrho cov baking hmoov. Nws yog kiag li decomposed rau gaseous Cheebtsam, tawm hauv tsis muaj cov zaub mov thiab tsis ntxim rau cov saj ntawm ci. Uas yog vim li cas nws yog li ntawd nrov ntawm confectioners. Qhov no cov ntaub ntawv uas tej zaum yuav siv nyob rau hauv tsis muaj tseeb dosing, txij thaum nyob rau hauv txhua rooj plaub nws yog kiag li decomposed, tso loj nyiaj ntawm cov roj cua. Ammonium carbonate muaj tsuas yog ib drawback - nws tsis ruaj tsis khov nyob rau hauv cov huab cua, tshwj xeeb tshaj yog thaum lub sij hawm ntev cia, li ntawd, ib tug tshuaj leavening neeg sawv cev yuav tsum tau muab cia rau hauv zoo-kaw iav, earthenware los yog tin ntim.

Lub lom leavening neeg sawv cev muaj xws li: lub keeb (muaj lactic acid cov kab mob) thiab ncuav poov xab (pwm uas muaj peev xwm ntawm tso carbon dioxide mus rau hauv lub khob noom cookie). Cov tshuaj ua fermentation nyob rau hauv lub khob noom cookie, uas kuj loosens. Thaum Sourdough - kuj ci hmoov mus rau qhov kev kuaj ntawd, tab sis nws tsis yog haum rau ua ncuav qab zib, ncuav, pastries. Lom ua hauj lawm yog siv rau ci khob cij thiab bakery cov khoom.

Dej qab zib, slaked vinegar - npaum ci hmoov. Qhov no txoj kev yog ua rau lub teb decomposition ntawm dej qab zib thiab txhim kho qhov saj ntawm lub confectionery khoom. Thaum lub sij hawm blanking yog tso tawm cov pa roj carbon dioxide, thiab thaum twg nws yog ntxiv rau lub khob noom cookie, ci yuav ntxeem tau thiab huab cua. Dej qab zib yog siv rau biscuits, ncuav, pastries thiab lwm yam ci khoom rau muab nws ntim. Tej bakers quenched nrog nws nyob rau hauv no txoj kev: cov hmoov nplej yog tov nrog dej qab zib thiab vinegar yog ntxiv rau kua, uas yog tswvcuab rau hauv lub hmoov (qaub cream, yogurt, qab zib). Thaum nws ntawm tag nrho cov khoom xyaw, cov pa roj carbon dioxide yuav nyob twj ywm hauv lub khob noom cookie. Lub ntsiab mob rau muab zoo ci nyob rau hauv cov ntaub ntawv no yog hais tias ib tug batter yuav tsum tau ci tam sim ntawd. Zoo quench dej qab zib thiab cov pa khoom noj siv mis (whey, kefir, yogurt, qaub cream).

Yog feem ntau siv thiab xws li ib tug muaj pes tsawg leeg rau khob noom cookie leavening neeg sawv cev: citric acid, dej qab zib, hmoov los yog hmoov txhuv nplej. Tej muaj pes tsawg leeg cov khoom xyaw tsis pub ntxov ntxov cov tshuaj tiv thaiv quenching. Qhov no xeem tsis yog ci hmoov yaj thiab tov nrog hmoov, ces ntxiv mus rau lub batter. quenching cov tshuaj tiv thaiv nyob rau hauv cov ntaub ntawv no yuav siv sij hawm qhov chaw tsuas yog nyob rau lub sij hawm ntawm ci. Qhov no ua khob noom cookie yuav tsum tau muab tseg rau ib tug, tsis txhob ci.

Ntawm cov tej yam ntuj tso khoom siv rau loosening xeem, nws yuav tsum tau muab sau tseg raws li nram no: agar-agar; cov rog, tov nrog piam thaj; gelatin; carrageenan; qe dawb; pectin; khoom noj siv mis creamer.

Nyob rau hauv lub muaj zus tau tej cov zaub mov no feem ntau siv thiab disintegrating gases. Cov no muaj xws carbon dioxide, cov pa roj nitrous oxide. Feem ntau lub hom phiaj no chav siv thiab ib txwm huab cua. Tej disintegration xeem txoj kev no tsuas yog siv tau nyob rau hauv lub muaj ntau lawm ntawm cov khoom.
