D-Sorbitol, MP Biomedicals™
D-Sorbitol is a sugar alcohol that occurs naturally and is also produced synthetically from glucose. Naturally, D-sorbitol occurs widely in plants via photosynthesis, ranging from algae to higher order fruits of the family Rosaceae.
The food industry uses D-sorbitol as an additive in the form of a sweetener, humectant, emulsifier, thickener, or dietary supplement. D-Sorbitol has also been found in cosmetics, paper, and pharmaceuticals. It was formerly used as a diuretic and may still be used as a laxative and in irrigating solutions for some surgical procedures.
D-Sorbitol may be used for washing spheroplasts and in isoelectric focusing to minimize endoosmotic flow in agarose gels. It may also be used to induce osmotic stress. Sorbitol can be used as a screen for the O154:H7 strain of E. coli, since this strain is one of the few strains which cannot metabolize sorbitol.
