✦ Synopsis
Beet colorant was tested for mutagenic activity in five S. typhimurium strains. The absence of mutagenic activity was found with or without S-9 rat liver fractions.
Groups of six rats were fed red beet colorant preparations containing 2,000 ppm betalains in the diet for 7 days. No significant differences were noted in body weight gains, feed consumption, or gross pathological alterations compared to the controls.
These preliminary toxicological results indicate the potential usage of betalain pigments as a food colorant, but further long term investigations are warranted.
