Tus yuam sij Qhov sib txawv ntawm enzymatic thiab nonenzymatic browning yog tus enzymatic browning Muaj cov enzymes xws li polyphenol oxidase thiab catechol oxidase whereas lub nonenzymatic browning tsis koom nrog enzymatic kev ua si.
Tib neeg kuj nug, qhov txawv ntawm enzymatic browning thiab oxidation yog dab tsi?
Enzymic browning yog ib oxidation cov tshuaj tiv thaiv uas tshwm sim hauv qee yam khoom noj, feem ntau yog txiv hmab txiv ntoo thiab zaub, ua rau cov zaub mov tig xim av . Oxidation kev tshwm sim tshwm sim hauv cov khoom noj thiab cov khoom tsis yog khoom noj. Enzymic browning yog ib qho tshuaj tiv thaiv uas yuav tsum tau ua ntawm cov enzymes thiab oxidation thiaj li tshwm sim.
Ib yam li ntawd, dab tsi yog enzymatic thiab tsis enzymatic browning? Enzymatic thiab Non - enzymatic browning ntawm cov zaub mov. Browning ntawm cov zaub mov tuaj yeem yog tsis yog - enzymatic (caramelization los yog maillard cov tshuaj tiv thaiv) los yog enzymatic . TSIS - ENZYMATIC BROWNING . Caramelization yog ib tsis yog - enzymatic Cov tshuaj tiv thaiv uas tshwm sim thaum cov carbohydrates lossis cov suab thaj hauv cov zaub mov tau rhuab.
Tsuas yog li ntawd, dab tsi yog enzymatic browning cov tshuaj tiv thaiv?
Enzymatic browning yog ib qho tseem ceeb tshaj plaws cov tshuaj tiv thaiv uas tshwm sim hauv cov txiv hmab txiv ntoo thiab zaub, feem ntau ua rau muaj qhov tsis zoo ntawm cov xim, saj, tsw, thiab khoom noj muaj txiaj ntsig. Cov tshuaj tiv thaiv yog qhov tshwm sim ntawm phenolic tebchaw 'oxidation los ntawm polyphenol oxidase (PPO), uas ua rau lub cim ntawm cov xim tsaus nti.
Dab tsi yog qhov txawv ntawm caramelization thiab Maillard browning?
Tus yuam sij Qhov sib txawv ntawm cov tshuaj tiv thaiv Maillard thiab caramelization yog tus Maillard tshuaj tiv thaiv yog non-pyrolytic whereas lub caramelization yog pyrolytic. Cov Maillard tshuaj tiv thaiv thiab caramelization yog ob txawv tsis yog enzymatic xim av cov txheej txheem ntawm cov khoom noj.
