Noo cov ntsiab lus ntawm qhob cij
Kev laus ntawm cov khob cij thaum khaws cia ze ze rau nws cov ntsiab lus noo noo. Yog tias cov ntsiab lus noo noo tsawg dua, lub khob cij yuav ua kom qhuav thiab tawv thiab slag yuav nrawm dua, thiab qhov kev laus ua haujlwm yuav nce siab. Txhawm rau ncua lub hnub nyoog ntawm cov khob cij thiab khaws cov mos mos ntawm lub khob ua kom ntev, cov ntsiab lus noo noo yuav tsum tswj xyuas nyob rau hauv qib siab tsis muaj kev cuam tshuam qhov tsis hnov mob thiab lub cev thiab tshuaj lom ntawm cov ncuav zoo. Txhawm rau ua kom cov khoom ntawm qee qhov ya raws cov ntsiab lus, ntau cov tuam ntxhab lees tias cov ntsiab lus siab dhau ntawm cov dej noo tuaj yeem yooj yim ua rau cov pwm tsis zoo thiab tsis zoo. Nyob rau lub sijhawm no, Baiqing hom ntuj mos mos moisturizing qab zib thiab qhob cij antiseptic tshuaj tiv thaiv tuaj yeem muab ntxiv rau tsis tsuas yog ua rau lub khob cij mos thiab noo, tab sis kuj ua tiav cov tshuaj tua kab mob thiab ua kom cov nyhuv tshiab.
Qhov kub ntawm lub khob cij cia
Kub yuav cuam tshuam ncaj qha rau kev laus ntawm lub ncuav. Lub hnub nyoog qeeb qeeb thaum lub sijhawm ua kom qhov chaw sov siab tshaj 30 ℃, qhov kev laus ntawm cov khob cij tuaj yeem ua kom nrawm nrawm nyob rau hauv ntau ntawm -7 20 -20 ℃, thiab qhov kev laus ua haujlwm nrawm tshaj ntawm 1 ℃. Yog li, sim ua kom tsis txhob dhau qhov ntsuas kub no tom qab lub khob cij ci, tshwj xeeb tshaj yog cov tuam txhab sab qaum teb yuav tsum them sai sai rau qhov no!
Gluten Protein
Feem ntau ua rau hmoov nplej muaj muaj protein ntau nyob thiab cov khob cij yog qhov hnyav, thiab cov laus siv qeeb me ntsis. Vim tias cov zaub mov muaj protein ntau, nws yuav ua kom lub zog ntawm cov hmoov txhuv nplej siab rov qab ua dua thiab ncua kev laus ntawm cov nqaij hauv cov mov. Mov ci laus kuj tseem cuam tshuam rau qhov zoo ntawm gluten protein hauv hmoov. Kev sib cuam tshuam ntawm qhov tsis zoo gluten hauv khob noom cookie thiab hmoov txhuv nplej siab muaj zog dua, thiab qhov kev sib txuam no yuav muaj zog dua thaum thiab tom qab ci. Yog li, cov mov ci ua nrog cov hmoov nplej tsis zoo yuav ua rau lub hnub nyoog sai dua.
Lipids
Qhov kub nce, cov gluten protein yog denatured, txoj hlua khi ntawm lipids thiab cov protein tsis muaj zog, thiab cov lipids yuav maj mam tig los ua ke nrog amylose thiab amylopectin. Tom qab cov hmoov txhuv nplej siab gelatinization, txoj kev rov ua dua ntawm cov hmoov txhuv nplej siab molecules yog inhibited vim qhov kev txiav txim ntawm lipids, yog li ua si qhov cuam tshuam los tiv thaiv kev laus ntawm lub khob cij. Tsis tas li ntawd, daim ntawv monomolecular ntawm lipids muaj kev sib cuam tshuam hydrophobic nrog cov hmoov txhuv nplej siab tsim, ua rau lub hnab ntawv ua txoj hauv kev, ua kom tsis txhob amylose lwg me me, thiab txwv cov kev hloov pauv ntawm gelatinized hmoov txhuv nplej siab microcrystalline cov kab ntawv.
Cov txheej txheem ntau lawm ntawm cov mov ci
Cov khob noom cookie muag nrog dej ntau hauv cov hmoov sib xyaw kom zoo dua cov laus dua li lub khob noom cookie tawv, tab sis lub khob noom cookie muag dhau lawm kuj tseem yuav cuam tshuam rau qhov zoo kawg nkaus ntawm cov khob cij, thiab nws yog qhov nquag ua tsis tau zoo; lub khob cij ci nrog lub siab sib xyaw ua khob noom cookie muag yog mos thiab muaj lub hnub nyoog qeeb qeeb, lub neej ua haujlwm ntev dua; lub sij hawm fermentation luv dhau, lub khob noom cookie tsis paub qab hau thiab lub khob cij laus tsis nrawm, thaum lub sijhawm fermentation ntev dhau lawm, lub khob noom cookie matures ntau dhau lawm thiab lub khob cij ci sai sai ua qhuav, thiab nws kuj yog qhov kev laus.
