Table 1. Calculated intake of monosodium L(+)-tartrate and L(+)-tartaric
acid in two-year feeding study
Monosodium L(+)-tartrate was fed to rats in their diet for a total of
two years at levels of 25600, 42240, 60160 and 76800 ppm. There were no
adverse clinical signs and the investigation of the animals' eyes, blood
and urine did not reveal any reaction to treatment, nor were changes
related to treatment seen in the macroscopic pathology or organ weights
of rats killed after 104 weeks. Histological examination of the tissues
did not show evidence of toxicity or tumour induction that could be
attributed to treatment with monosodium L(+)-tartrate. Only the survival
of rats receiving 42240, 60160 or 76800 ppm was superior to that of the
controls and probably correlated with the lower food intake of these
groups and the resultant reduced bodyweight gain.
