Beschreibung

Allgemeine Beschreibung

meso-Erythritol, belonging to the class of sugar alcohols, is identified in a variety of food products, fruits, vegetables, beverages and dietary supplements. It is known as a low glycemic food additive and plays an important role as a sweetener for diabetic patients, since it does not have glycemic or insulinemic effect due to its ability to not get metabolized but get absorbed in the small intestine. It is also reportedly used as a sugar substitute in toothpaste, chewing gums, confectionery food products, etc.

Anwendung

meso-Erythritol may be used as an analytical reference standard for the quantification of the analyte in:

• Food products using high-pressure liquid chromatography coupled to charged aerosol detector (HPLC-CAD).
• Confectioneries using high-performance liquid chromatography with UV detection (HPLC-UV).
• Food and beverages using liquid chromatography with UV detection (LC-UV).

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Biochem./physiol. Wirkung

Allelische Variation des Tas1r3-Gens beeinflusst die verhaltensbezogene Geschmacksreaktion auf diesen Zuckeralkohol, was darauf hindeutet, dass er ein T1R3-Rezeptorligand ist.
