Hauv kev lag luam khoom noj khoom haus, HPMC tuaj yeem txhim kho qhov farinaceous thiab tensile zog ntawm lub khob noom cookie. Tsis tas li ntawd, qhov sib ntxiv ntawm Hydroxypropyl Methyl cellulose etherHPMCtxo qhov nce ntawm cov dej khov hauv lub khob noom cookie thaum lub sij hawm khov, yog li inhibiting cov nyhuv ntawm cov dej khov crystallization ntawm lub khob noom cookie network qauv. Qhov kev puas tsuaj tswj cov txheeb ze ruaj khov thiab kev ncaj ncees ntawm nws cov qauv, yog li muab kev lees paub rau qhov zoo ntawm cov khoom kawg. Ntawm qhov tod tes, qhov sib ntxiv ntawm HPMC kuj muaj kev tswj xyuas zoo thiab txhim kho cov txiaj ntsig ntawm steamed bread. Rau cov qauv tsis khov, qhov sib ntxiv ntawm HPMC nce qhov ntim tshwj xeeb ntawm cov khob cij steamed thiab txhim kho cov khoom zoo nkauj ntawm cov qhob cij steamed; thaum lub sijhawm ntxiv ntawm lub sijhawm khov, qhov sib ntxiv ntawm HPMC inhibited qhov tsis zoo ntawm cov khob cij steamed ua los ntawm cov khob noom cookie khov. Qhov no qhia tau tias HPMC tuaj yeem siv rau kev ua cov khob cij khov nrog cov khob cij steamed ua cov khoom kawg, thiab muaj txiaj ntsig zoo rau kev txhim kho qhov zoo ntawm cov khob cij steamed.
(2) Kev sim tau pom tias cov qauv gluten tsis muaj HPMC raug rhuav tshem vim qhov tsim thiab kev loj hlob ntawm cov dej khov nab kuab, cov elastic modulus poob qis, cov ntsiab lus thiol dawb tau nce ntau, thiab lub network microstructure raug rhuav tshem; Txawm li cas los xij, qhov sib ntxiv ntawm HPMC tuaj yeem cuam tshuam qhov kev hloov pauv no, tshwj xeeb tshaj yog thaum qhov sib ntxiv yog 2%, piv nrog rau pawg tswj hwm, cov ntsiab lus ntawm cov pab pawg sulfhydryl dawb, cov ntsiab lus ntawm cov dej khov thiab qhov cuam tshuam ntawm pawg hydrophobic raug txo, thaum cov qauv theem nrab thiab microscopic network qauv ntawm gluten tseem nyob ruaj khov. Qhov no yog vim HPMC tuaj yeem txo qhov kev txav mus los ntawm cov dej thiab txwv qhov nce ntawm cov dej khov dej khov, yog li txo qhov kev puas tsuaj rau qhov kev sib haum xeeb thiab kev sib txuas ntawm gluten protein los ntawm cov dej khov.
(3) Qhov kev sim pom tau tias tom qab 60 hnub ntawm qhov khov khov, cov gelatinization cov yam ntxwv ntawm cov hmoov txhuv nplej siab tag nrho nce, cov gelatinization enthalpy tau nce ntau, thaum lub zog gel ntawm cov hmoov txhuv nplej siab txo qis, uas qhia tau tias cov qauv ntawm cov hmoov txhuv nplej siab tau hloov pauv (kwv yees crystallinity nce ntxiv. tseem ceeb). , cov qib ntawm cov hmoov txhuv nplej siab nce ntxiv); Txawm li cas los xij, cov hmoov txhuv nplej siab nrog HPMC ntxiv, cov hmoov txhuv nplej siab tseem nyob ruaj khov tom qab khov, yog li txo qhov kev hloov pauv ntawm gelatinization cov yam ntxwv, gelatinization enthalpy, gel zog, thiab lwm yam. Nws qhia tau hais tias qhov sib ntxiv ntawm HPMC tuaj yeem cuam tshuam cov nyhuv ntawm cov dej khov. ntawm cov qauv thiab cov khoom ntawm haiv neeg hmoov txhuv nplej siab granules.
(4) Qhov kev sim qhia tau hais tias piv nrog rau pawg tswj hwm, qhov sib ntxiv ntawm HPMC tuaj yeem tswj tau cov kev ua fermentation ntawm cov poov xab, inhibit qhov poob ntawm fermentation qhov siab ntawm lub khob noom cookie thiab cov ciaj sia taus ntawm cov poov xab tom qab khov rau 60 hnub, li no txo cov extracellular txo hom. Qhov nce ntawm glutathione cov ntsiab lus, thiab nyob rau hauv ib tug tej yam ntau yam, kev tiv thaiv nyhuv ntawm HPMC tau zoo correlated nrog nws cov nyiaj ntxiv. Qhov no qhia tias HPMC tuaj yeem tiv thaiv cov poov xab los ntawm inhibiting kev tsim thiab kev loj hlob ntawm cov dej khov nab kuab.
6.2 Outlook
(1) Txhawm rau kawm ntxiv txog qhov cuam tshuam ntawm kev ntxiv HPMC ntawm lub iav hloov pauv kub (H) ntawm cov khob noom cookie khov, cov fermentation kinetics ntawm cov poov xab thiab qhov tsw ntawm steamed qhob cij, nrog rau kev tsim, kev loj hlob, thiab rov faib cov ice crystals hauv khov khob noom cookie, thiab lwm yam. Yog li ntawd, cov hom tshiab uas muaj kev ntxhov siab tsis haum rau cov khob noom cookie khov tau raug xaiv, thiab ib qho kev siv rau kev tsim khoom thiab kev thauj mus los txias ntawm cov khob noom cookie khov thiab lwm yam khoom noj khov tau muab.
(2) Kawm ntxiv txog kev txhim kho cov txiaj ntsig ntawm HPMC ntawm qhov zoo ntawm cov khob noom cookie khov thiab nws cov khoom nyob rau lub sijhawm khov khov ntev dua, thiab tshawb xyuas cov ntawv thov ntawm HPMC hauv lwm hom khob noom cookie khov.
(3) Kev ua kom zoo ntxiv rau daim ntawv qhia ua khob noom cookie khov thiab cov txheej txheem tsis ua raws li qhov tseeb ntawm cov qhob cij steamed, txhawm rau txhim kho thiab txhim kho qhov zoo ntawm cov khob noom cookie steamed qhob cij khoom, thiab tib lub sijhawm tswj thiab txo cov khoom lag luam. nqi. Tsis tas li ntawd, daim ntawv thov ntawm HPMC nyob rau hauv khov khob noom cookie Suav-style pasta khoom kuj tseem yuav nthuav dav, thiab ntau tus qauv tsim thiab hom khoom tuaj yeem tsim kom tau raws li cov kev xav tau ntawm cov neeg siv khoom.
