Description

Maltol is a naturally occurring organic compound isolated from pine needles, larch bark, the destructive distillates of various organic materials and the alkaline hydrolysis products of streptomycin. Because of caramel-butterscotch odor, and suggestive of fruity-strawberry aroma in dilute solutions, maltol is used as a food additive mainly in confectionary and bakery products. Maltol is considered safe by FDA according to existing data and granted GRAS status. Maltol chelates metal ions such as Fe3+, Al3+, and is reported to increase uptake of aluminum and iron in the body. Maltol was reported to have a neuroprotective effect on retinal ganglion cells under oxidative stress, and hepatoprotective effect on alcohol-induced liver oxidative injury.

Sample Use Guides

In Vivo Use Guide
Maltol is used in many products, mainly confectionary and bakery products. The acceptable daily intake is up to 1 mg/kg bodyweight.
Route of Administration: Oral
In Vitro Use Guide
When the retinal ganglion cells were exposed to 20 μM of H2O2 for 16 h, their viability dropped to 40.3±3.4%. However, the maltol treatment restored the cells in a dose-dependent manner. The viability recovered to 73.9±5.1% with 10 μM of maltol and even reached 175.1±11.3% with 2 mM of maltol, as measured by ATP assay.
