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 kawirikawiri mu uchi, timadziti ta zipatso, mafuta opangira mafuta a munthu, 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
