Glucono delta lactone (GDL) is a natural constituent of many foods. It can be found in honey, fruit juices, wine and many fermented products. As a natural food acid it contributes to the tangy flavor of various foods and since it lowers the pH it also helps preserve the food from deterioration by enzymes and microorganisms.

Description:

Glucono delta lactone is a carbohydrate that contains a lactone formation. In an aqueous solution there is an equilibrium between gluconic acid and the delta and gamma lactones.

General Characteristics:

Chemical Name:
D-Glucono-1,5-lactone
Molecular Weight:
178.14
Formula:
C6H10O6
Melting Point:
153°C
Solubility:
59g/100 mL (water) at 25° C

Standard Specifications:

(FCC V)
Meet the specifications outlined in the Food Chemicals Codex. Glucono delta lactone is recognized as a GRAS (Generally Recognized as Safe) food additive

Application:

GDL is commonly found in honey, fruit juices, and wine. Being acidic, it adds a tangy taste to foods, though it has roughly a third of the sourness of citric acid. It is metabolized to glucose; one gram of GDL is equivalent to one gram of sugar. In processed foods, GDL functions as a curing and pickling agent; leavening agent; pH control agent; and sequestrant.

Standard Packaging & Availability:

Glucono Delta Lactone is packaged in 25kg lined, multi-walled paper bags. These are available with or without a dessicant bag.

Storage & Handling:

Glucono Delta Lactone should be stored at room temperature in a dry location.

S-45 | PMP Fermentation Products, Inc

While other compounds share these properties, gluconate is a superior sequestrant and remains stable even in high alkalinity and extremes of temperature. This product is a weak organic acid solution, so it is preferable to use stainless steel, or plastic and glass equipment when storing or handling. Gluconates are important industrial chemicals because they employ the principles of sequestration and chelation under unique circumstances.
