Glucono-Delta-Lactone (GDL) - 90-80-2

Glucono delta-lactone (GDL) ndi chowonjezera chachilengedwe chopezeka ndi E575 chomwe chimagwiritsidwa ntchito ngati sequestrant, acidifier, kapena kuchiritsa, pickling, kapena chotupitsa.Ndi lactone (cyclic ester) ya D-gluconic acid.GDL yoyera ndi ufa wonyezimira wopanda fungo.

GDL imapezeka kwambiri mu uchi, timadziti ta zipatso, mafuta opangira mafuta amunthu, ndi vinyo.GDL salowerera ndale koma imasungunuka m'madzi kupita ku gluconic acid yomwe imakhala acidic, kuonjezera kukoma kwa zakudya, ngakhale ili ndi pafupifupi gawo limodzi mwa magawo atatu a citric acid wowawasa.Imasinthidwa kukhala glucose;gilamu imodzi ya GDL imatulutsa mphamvu ya kagayidwe kachakudya yofanana ndi gramu imodzi ya shuga.

Kuphatikiza pa madzi, GDL imapangidwa pang'ono ndi hydrolyzed kukhala gluconic acid, ndikuyezera pakati pa mawonekedwe a lactone ndi mawonekedwe a asidi omwe amakhazikitsidwa ngati kufanana kwa mankhwala.Mlingo wa hydrolysis wa GDL ukuwonjezeka ndi kutentha ndi mkulu pH
