Qhov sib txawv ntawm vinegar thiab enzyme fermentation

Ua ntej ntawm tag nrho cov, nyob rau hauv cov nqe lus ntawm raw khoom xaiv, enzymes txawv ntawm caw thiab vinegar. Cov khoom siv raw muaj dav dua. Txiv hmab txiv ntoo thiab zaub, tshuaj thiab zaub mov homologous cov ntaub ntawv kho mob tuaj yeem siv los ua fermentation raw khoom. Thib ob, los ntawm kev noj zaub mov zoo, cov enzymes tau tsom mus rau cov mis uas muaj cov khoom noj muaj txiaj ntsig. Thaum kawg, los ntawm kev siv thev naus laus zis, cawv thiab kua txiv hmab txiv ntoo yog cov khoom lag luam zoo fermentation, thiab cov fermentation raug txiav tawm tom qab qee lub sijhawm, thiab qhov tseem ceeb ntawm kev nrhiav yog qhov saj. Enzymes yog cov khoom ntawm kev sib sib zog nqus fermentation uas ib txhij ua dej cawv thiab acidification. Tsis muaj qhov yuav tsum tau txiav tawm fermentation. Qhov ntau dua qhov zoo dua, kev nrhiav siab yog siab {{0}}}cov enzymes concentration, ntau cov kab mob, thiab cov metabolites thawj thiab theem nrab. Feem ntau, cov khoom siv ntawm cov kua txiv hmab txiv ntoo thiab cov enzymes zoo sib xws, thiab cov txheej txheem tsim khoom pib kuj zoo ib yam, uas yog siv cov kab mob saccharifying los faib cov hmoov txhuv nplej siab hauv cov khoom siv raw rau hauv cov khoom me me thiab tsim ib feem ntawm cawv. Tab sis cov kauj ruam tom ntej ntau lawm txawv heev. Vinegar yog inoculated nrog cov kab mob acetic acid, thiab cov kab mob acetic acid yuav oxidize cawv rau hauv acetic acid, thiab tom qab ntawd teem lub acidity raws li kev tsim khoom. Feem ntau, tus nqi pH ntawm acetic acid yog li 2.0-3.0. Thaum lub acidity ncav cuag tus nqi no, nws yog ib qhov tsim nyog yuav tau siv sterilization engineering los tua cov kab mob acetic acid, txwv tsis pub cov acidity yuav ua rau acidic ntau dua, yog li lub vinegar tsis muaj cov kab mob nyob. Tom qab saccharification, enzymes yuav dhau mus txawv qib ntawm fermentation. Cov kab mob ntuj feem ntau yog siv los ua cov kab mob no zais cov qib sib txawv ntawm cov ntsiab lus enzyme thaum lub sijhawm fermentation. Yog li, cov khoom lag luam enzyme muaj txiaj ntsig zoo rau tib neeg lub cev. Cov kab mob nyob. Kev sib raug zoo ntawm peb qhov no tuaj yeem nkag siab zoo li: kev ua cawv txiv hmab yog anaerobic fermentation, vinegar brewing yog anaerobic ua ntej thiab tom qab ntawd aerobic, thaum ua cov enzymes yog anaerobic fermentation thiab aerobic fermentation tib lub sijhawm, thiab tom qab theem yog feem ntau anaerobic fermentation, uas. tuaj yeem siv sijhawm ntev. Txog li 1-2 xyoos.
