Glucono-Delta-Lactone(GDL)｜90-80-2
Oloa Fa'amatalaga
Glucono delta-lactone (GDL) ose mea'ai fa'aopoopo fa'anatura fa'atasi ma le numera E E575 fa'aaogaina e fai ma sui, fa'asa'o, po'o se fofo, piki, po'o se mea fa'afefete. O se lactone (cyclic ester) o le D-gluconic acid. GDL mama ose pa'epa'e e leai se manogi pa'u tioata.
E masani ona maua le GDL i le meli, sua o fualaau aina, lubricants patino, ma le uaina [sii mai]. GDL e le fa'aituau ae fa'asusu i le vai i le gluconic acid lea e fa'ama'i, fa'aopoopoina ai se tofo manogi i mea'ai, e ui e tusa ma le tasi vaetolu o le oona o le citric acid. E metabolized i le kulukose; e tasi le kalama o le GDL e maua mai ai e tusa ma le aofa'i tutusa o le malosi fa'afoma'i ma le kalama e tasi o le suka.
I luga o le faʻaopoopoga i le vai, o le GDL o loʻo faʻapipiʻiina se vaega i le gluconic acid, ma le paleni i le va o le lactone form ma le acid form na faʻavaeina o se vailaʻau paleni. Ole fua ole hydrolysis ole GDL e faʻateleina ile vevela ma maualuga pH
