90-80-2 Usage

Uses

A lactone (cyclic ester) of D-gluconic acid used as a used as a sequestrant, an acidifier, or a curing, pickling, or leavening agent.

Chemical Properties

Powder

Uses

chelating agent

Description

Delta-Gluconolactone (GDL) is a lactone of the D-gluconate. It is a natural constituent of many foods. It can be found in honey, fruit juices, wine and many-fermented products1-3. It is used as a food additive with the E number E575 used as a sequestrant, an acidifier (it lower the pH and also help preserve the food from deterioration by enzymes and organisms), or a curing, pickling, or leavening agent. GDL has been marketed for use in feta cheese. GDL is neutral, but hydrolyses in water to gluconic acid that is acidic, adding a tangy taste to foods, though it has roughly a third of the sourness of citric acid. It can be used as nutritional supplement in beverage such as in Instant Drinks, Syrups, RTD Tea and Coffee, Sports and Energy Drinks, Waters.

Uses

Component of many cleaning cmpds because of the sequestering ability of the gluconate radical which remains active in alk solutions; in the dairy industry to prevent milkstone; in breweries to prevent beerstone; as latent acid catalyst for acid colloid resins, particularly in textile printing; as a coagulant for tofu.

Purification Methods

Crystallise Dglucono- -lactone from ethylene glycol monomethyl ether and dry for 1hour at 110o. It can be freed from other sugars via a column of Celite and charcoal (750g of each, 90 x 7.5cm) which is washed with 0.01N formic acid until the pH of the wash is equal to that of the entering acid. The lactone is applied in H2O and eluted with 0.01N formic acid (7L), then eluted with 7.5% EtOH/0.01N formic acid (8L), then 15% EtOH/0.01N formic acid (8L) which removes pentose and isomaltose (the optical rotation of the eluates are used for sugar detection) and finally elution with aqueous formic acid provides glucolactone which is obtained by evaporating or freeze drying. Its solubility in H2O is 60% and 1% in EtOH. A solution in H2O is slightly acidic, and the lactone dissolves in an equivalent of aqueous NaOH to form sodium D-gluconate [527-07-1] M 218.1, m 200- 2 0 6o(dec), [ ] D 25 +12o (c 10, H2O), pK2 5 3.6. [cf p 553, Smith & Whelan Biochemical Preparations 10 127 1963, Beilstein 3 IV 1255.]

Uses

D-glucono-1,5-lactone is the lactone derivative of D-gluconic acid. D-glucono-1,5-lactone is widely used as a food additive to achieve a curing, pickling or leavening effect.

Uses

Geogard(R)Ultra is a synergistic blend of gluconolactone and sodium benzoate. This blend provides broad spectrum protection against product spoilage in a variety of personal care formulations. Product Data Sheet
