Glucono-Delta-Lactone (GDL) ｜90-80-2
Nkọwa ngwaahịa
Glucono delta-lactone (GDL) bụ ihe mgbakwunye nri na-emekarị yana nọmba E575 ejiri mee ihe dị ka sequestrant, acidifier, ma ọ bụ ọgwụgwọ, pickling, ma ọ bụ ihe iko achịcha. Ọ bụ lactone (cyclic ester) nke D-gluconic acid. GDL dị ọcha bụ ntụ ntụ kristal na-enweghị isi.
A na-ahụkarị GDL na mmanụ aṅụ, ihe ọṅụṅụ mkpụrụ osisi, mmanụ mmanu onwe onye, na mmanya[ntụgharị chọrọ]. GDL na-anọpụ iche mana hydrolyzes n'ime mmiri na gluconic acid nke bụ acidic, na-agbakwunye uto na-atọ ụtọ na nri, n'agbanyeghị na ọ nwere ihe dịka otu ụzọ n'ụzọ atọ nke utoojoo nke citric acid. A na-emezi ya ka ọ bụrụ glucose; Otu gram nke GDL na-ewepụta ihe dị ka otu gram ike metabolic dị ka otu gram shuga.
Na mgbakwunye na mmiri, GDL na-edobe akụkụ nke hydrolyzed na gluconic acid, yana nguzozi n'etiti ụdị lactone na ụdị acid guzobere dị ka nha kemịkalụ. Ọnụego hydrolysis nke GDL na-abawanye site na okpomọkụ na pH dị elu
