Kev Tsim Tawm Ntawm Invertase Enzyme Inverted qab zib syrup tuaj yeem ua yam tsis muaj cov kua qaub lossis enzymes los ntawm cua sov nws ib leeg: ob ntu granulated qab zib thiab ib feem dej, simmered rau tsib mus rau xya feeb, yuav yog ib nrab inverted. Kev lag luam npaj cov tshuaj enzyme-catalysed yog inverted ntawm 60 ° C (140 ° F).
Invertase enzyme tsim nyob qhov twg?
Invertase yog tsim los ntawm cov kab mob sib txawv, Saccharomyces cerevisiae feem ntau hu ua Baker's poov xab yog thawj hom siv rau kev tsim cov khoom lag luam Invertase. Lawv pom nyob rau hauv qus loj hlob ntawm daim tawv nqaij ntawm txiv hmab txiv ntoo, txiv kab ntxwv thiab lwm yam txiv hmab txiv ntoo
Pob tib neeg tsim invertase?
Invertase muaj nyob hauv tib neeg qaub ncaug. Nws yog tsim los ntawm cov kab mob, Streptococcus mutans, muaj nyob hauv cov quav hniav.
Thaum twg tau pom invertase?
Mitscherlich tau piav qhia hauv 1842 qhov muaj nyob hauv cov poov xab ntawm cov khoom muaj peev xwm hloov pauv dextrorotatory cane qab zib mus rau hauv cov suab thaj levorotatory uas tau txheeb pom hauv xyoo 1847 los ntawm Dubrunfaut raws li kev sib xyaw ntawm qabzib thiab fructose. Hauv 1860, thawj zaug, Berthelot tau ua qhov kev sib cais ntawm invertase (saib Ref. 1).
Puas yog invertase tib yam li invert qab zib?
Cov khoom no yog technically lub tib yam li cov qab zib syruptab sis qee zaum lub npe menyuam yaus "cov zib ntab" ua tsaug rau nws cov zib ntab zoo li tsw. Honey. Honeybees tsim ib qho enzyme hu ua invertase uas tso cai rau lawv ua kom cov sucrose nyob rau hauv cov piam thaj hloov pauv ntawm cov piam thaj thiab fructose. Invert maple phoov.
