Glucono-Delta-Lactone(GDL)｜90-80-2
Huahana Huahana
ʻO Glucono delta-lactone (GDL) he mea hoʻohui meaʻai maoli me ka helu E E575 i hoʻohana ʻia ma ke ʻano he sequestrant, he mea hoʻoheheʻe, a i ʻole he lāʻau hoʻōla, pickling, a mea huʻi. He lactone (cyclic ester) o D-gluconic acid. ʻO ka GDL maʻemaʻe he pauka crystalline keʻokeʻo ʻole.
Loaʻa pinepine ʻia ka GDL i loko o ka meli, nā wai huaʻai, nā lubricants pilikino, a me ka waina. ʻAʻole kūʻokoʻa ka GDL akā hydrolyze i ka wai i ka waika gluconic he ʻakika, e hoʻohui ana i kahi ʻono ʻono i nā meaʻai, ʻoiai he hapakolu o ka ʻona o ka waikawa citric. Hoʻopili ʻia ia i ka glucose; ʻO ka nui o ka ikehu metabolic e like me hoʻokahi gram o ke kō.
Ma kahi o ka wai, ua hoʻokahe ʻia ʻo GDL i ka waikona gluconic, me ke koena ma waena o ke ʻano lactone a me ke ʻano waikawa i hoʻokumu ʻia ma ke ʻano he equilibrium kemika. Hoʻonui ʻia ka nui o ka hydrolysis o GDL e ka wela a me ka pH kiʻekiʻe
