1. Taw qhia
Gluconolactone yog ib qho ester tsim los ntawm lub cev qhuav dej ntawm pawg carboxyl thiab pawg hydroxyl hauv gluconic acid molecule. Tshwj xeeb, ester tsim los ntawm lub cev qhuav dej nrog pawg hydroxyl ntawm 5th (δ- txoj hauj lwm) carbon atom yog hu uaδ -gluconolactone, thaum lub ester tsim los ntawm lub cev qhuav dej nrog pawg hydroxyl nyob rau 4th ( - txoj hauj lwm) carbon atom hu ua-gluconolactone.
Nws tshwm sim raws li cov khoom siv crystalline thiab muaj qhov qab zib saj txawv ntawm gluconic acid. Nws decomposes ntawm 153 degree, nrog rau ib qho kev sib hloov [ ]D20 ntawm +61.7℃(C=1, hauv dej). Soluble nyob rau hauv dej, nws hydrolyzes rau hauv gluconic acid nyob rau hauv aqueous daws, tsim ib tug equilibrium sib tov nrog cov δ thiab lactone isomers.
2. Muaj nuj nqi
(1) Nws hydrolyzes hauv aqueous daws los tsim gluconic acid, uas coagulates proteins. Tofu ua nrog gluconolactone nthuav tawm cov dej khaws cia zoo heev, kev ntxhib los mos zoo nkauj, thiab tus saj, kev sib tw, thaum tseem muab cov txiaj ntsig zoo rau cov taum paj.
(2) Raws li ib tug preservative, nws inhibits kev loj hlob ntawm pwm thiab kab mob. Nws tuaj yeem siv los khaws cov ntses, nqaij, nqaij qaib, cw, thiab lwm yam khoom lag luam, tswj lawv cov tsos zoo li tsis muaj xim av thiab khaws cov elasticity ntawm cov nqaij.
(3) Raws li tus neeg sawv cev leavening, thaum ua ke nrog sodium bicarbonate, nws tsim cov hmoov ci. Thaum lub sij hawm cua sov, gluconic acid reacts nrog sodium bicarbonate kom tso carbon dioxide, xa ib tug superior leavening nyhuv yam tsis muaj tawm - tsw.
3. Daim ntawv thov
3.1.Gluconolactone tuaj yeem siv los ua kom ruaj khov thiab coagulant, siv tau rau cov khoom lag luam taum (tofu thiab soybean pudding), hnyuv ntxwm (nqaij hnyuv ntxwm), cov khoom surimi, thiab kua txiv hmab txiv ntoo, nrog rau qib siab tshaj plaws ntawm 3.0g / kg.
3.2.Raws li kev khaws cia, nws tsim nyog rau cov tshiab - khaws cov ntses thiab cw, nrog rau qib siab tshaj plaws ntawm 0.1g / kg thiab qhov seem ntawm 0.01mg / kg.
3.3.Tsis tas li ntawd, nws tuaj yeem ua tus neeg sawv cev rau kev tsim cov hmoov ci hmoov, siv kom tsim nyog raws li kev xav tau ntau lawm.
3.4.Nws kuj yog siv dav hauv tshuaj pleev ib ce, textiles, papermaking, pharmaceuticals, thiab lwm yam.
