| IDENTIFICATION AND USE: Ethyl vanillin forms fine crystalline needles and is used in fragrances for its vanilla odor. It is also used as a replacement of or to strengthen the flavor of vanilla in a variety of foods. Ethyl vanillin is a widely used food additive and spice in foods, beverages, cosmetics and drugs. HUMAN EXPOSURE AND TOXICITY: Research in humans showed that ethyl vanillin had no significant effect on the activity of five human CYP450 enzymes with concentration ranged from 8 to 128 uM. A 2% concentration of ethyl vanillin caused mild irritation on the skin of humans after 48 hours of direct contact. ANIMAL STUDIES: In animal studies, ethyl vanillin was found to be mostly non-toxic except when given at high doses for longer than 6 weeks. Rabbits were given ethyl vanillin orally in 10% aqueous glycerin 49 mg/kg bw/day for 43 days. At this dose level anemia, diarrhea and lack of weight gain were observed. Rats (20/sex/group) were fed ethyl vanillin of > 99.9% purity (nature of diet e.g., semi-synthetic/chow diet, not specified) at dose levels of 0, 500, 1000 or 2000 mg/kg bw/day for 13 weeks. Clinical biochemistry showed statistically significant higher values in the high-dose group compared to control for ALAT, ALP, cholesterol and total plasma protein. Histological examination revealed a dose-related increased incidence of hepatic peribiliary inflammatory change in both males and females of the intermediate- and high-dose groups, and minor bile duct hyperplasia affecting 1/20 intermediate- and 4/20 high-dose males. There were no changes observed in the liver parenchyma and no degenerative or inflammatory changes of the bile duct epithelium. Increased white pulp cellularity and prominence of germinal centers in the spleen, and increased prominence of germinal centers and lymphoid proliferation in cervical lymph nodes were seen in the intermediate- and high-dose groups. Groups of 12 male and 12 female rats were fed diets containing 0, 0.5, 1 and 2% ethyl vanillin for 2 years or 2% and 5% for one year without any adverse effects on growth, organ weights of major organs, hematology and histology of major tissues. In genotoxicity studies, ethyl vanillin did not induce genetic changes in vitro but was reported to enhance the ability of mitomycin C to cause sister chromatid exchanges. Ethyl vanillin has shown to have anti-angiogenic, anti-inflammatory and anti-nociceptive properties that are based on its suppressive effect on the production of nitric oxide possibly via decreasing the reactive oxygen species level. The in vivo results revealed that drug interaction between vanillin/ethyl vanillin and drugs metabolized by CYP2E1 or CYP1A2 might be possible, and also suggested that the application of the above additives in foods and drugs should not be unlimited so as to avoid the adverse interaction. The thermal tolerance Cronobacter sakazakii was examined in sterile powdered infant formula (PIF) rehydrated at 58 °C in water or apple juice supplemented with vanillin, ethyl vanillin, or vanillic acid. All three compounds decreased thermal tolerance during-rehydration. Supplementation of PIF with vanillin, ethyl vanillin, or vanillic acid could enhance the safety of PIF or other dehydrated foods contaminated with C. sakazakii. |
