Glucono-Delta-Lactone (GDL) ｜ 90-80-2
Ibicuruzwa bisobanura
Glucono delta-lactone (GDL) ninyongeramusaruro yibiribwa bisanzwe hamwe na E nimero E575 ikoreshwa nkikurikiranya, acide, cyangwa umuti, umutobe, cyangwa umusemburo. Ni lactone (cyclic ester) ya aside D-gluconic. GDL yuzuye ni ifu yera idafite impumuro nziza.
GDL ikunze kuboneka mubuki, imitobe yimbuto, amavuta yumuntu, na vino. GDL ntaho ibogamiye ariko hydrolyzes mumazi kuri acide gluconique irimo aside, ikongeramo uburyohe bwa tangy kubiribwa, nubwo ifite hafi kimwe cya gatatu cyubushyuhe bwa acide citric. Ihinduranya glucose; garama imwe ya GDL itanga hafi yingufu zingana na garama imwe yisukari.
Usibye amazi, GDL igice cya hydrolyz kuri acide gluconique, hamwe nuburinganire hagati yimiterere ya lactone nuburyo bwa aside yashizweho nkuburinganire bwimiti. Igipimo cya hydrolysis ya GDL cyiyongera kubushyuhe na pH nyinshi
