Glucono-Delta-Lactone (GDL) ｜90-80-2
Sharaxaada Alaabta
Glucono delta-lactone (GDL) waa cunto lagu daro si dabiici ah oo leh E nambarka E575 oo loo isticmaalo sidii sequestrant, aashitode, ama daawo, qashin, ama wakiilka khamiirka.Waa lactone (cyclic ester) ee D-gluconic acid.GDL saafi ah waa budo crystalline cad oo aan ur lahayn.
GDL waxaa caadi ahaan laga helaa malabka, casiirka miraha, saliidaha gaarka ah, iyo khamriga[xigasho ayaa loo baahan yahay].GDL waa dhexdhexaad laakiin hydrolyzes ee biyaha si gluconic acid kaas oo ah acidic, ku daraya dhadhan macaan cuntooyinka, inkastoo ay leedahay qiyaastii saddex meelood meel dhanaan ee citric acid.Waxaa la dheefshiido ilaa gulukoos;Hal garaam oo GDL ah waxa uu soo saaraa qiyaas la mid ah tamarta dheef-shiid kiimikaadka sida hal garaam oo sonkor ah.
Marka lagu daro biyaha, GDL qayb ahaan waxaa lagu shubaa hydrolyzed gluconic acid, iyada oo dheellitirka u dhexeeya qaabka lactone-ka iyo qaabka aashitada loo aasaasay sida dheellitirka kiimikada.Heerka hydrolysis ee GDL waxaa ku kordhay kulayl iyo pH sare
