Full Description

Lactobionic Acid (CAS 96-82-2) is a disaccharide aldonic acid formed from beta-D-galactose and D-gluconic acid (the oxidation product of lactose), supplied as a white powder. It carries antioxidant functionality and is the parent acid of calcium lactobionate, a soluble calcium salt.

Frequently Asked Questions

What is Lactobionic Acid?

Lactobionic Acid (CAS 96-82-2) is a disaccharide aldonic acid formed from beta-D-galactose and D-gluconic acid, the oxidation product of lactose, supplied as a white powder (C12H22O12). It carries antioxidant functionality and is the parent acid of soluble metal salts such as calcium lactobionate.

Is lactobionic acid the same as lactic acid?

No. Lactobionic acid is a polyhydroxy aldonic acid derived from lactose (CAS 96-82-2, C12H22O12), while lactic acid is a small hydroxycarboxylic acid (CAS 50-21-5, C3H6O3). They are chemically distinct materials with different molecular weights and properties.

What is lactobionic acid used for industrially?

Lactobionic acid is used as an antioxidant functional ingredient and as the parent acid for producing soluble metal lactobionate salts, notably calcium lactobionate. RawSource supplies it as a powder raw material to formulators and salt manufacturers.

What is lactobionic acid made from?

Lactobionic acid is produced by the oxidation of lactose (milk sugar), which converts the glucose unit to a gluconic-acid moiety while retaining the galactose unit. The result is a disaccharide aldonic acid, CAS 96-82-2.

What bulk packaging and documentation are available for Lactobionic Acid?

RawSource supplies Lactobionic Acid powder in bulk industrial packaging to manufacturers, with Certificate of Analysis and SDS provided on request. Submit your target volume and grade requirements for a current bulk quote and lead time.
