The response of hamsters to a natural-type diet containing emulsifiers


, : The response of hamsters to a natural-type diet containing emulsifiers. Food Res 22(3): 273-286

Two ex-periments are reported in which a hydrogenated vegetable oil (Primex), polyoxyethylene (8) monostearate (Myrj 45), a mixture of meat and vegetable monoglycerides and diglycerides (Esterine) and cottonseed oil monoglycerides (Myverol 18-85) were fed to hamsters at varying levels from 5 to 20% of a diet composed of natural ingredients and simulating the American diet for varying periods up to 10 weeks. No abnormalities in behavior or physical appearance were observed in any of the hamsters at any time during the feeding periods. Diarrhea was not observed in any of the groups and no mortality was attributable to diet. No significant differences in weight gains were noted among the 3 groups fed Myrj 45, Esterine, or Myverol 18-85 although all groups grew at a somewhat retarded rate compared with the group fed Primex. Although with Myrj 45 at the 20% level growth was somewhat retarded, the combination of 10% Primex and 10% Myrj 45 resulted in a rate of gain and efficiency of calorie utilization equal to that of the 20% Primex group. The high voluntary food intake of the Myrj 45 group was related to the low calorie density of that diet. The gross appearance of the animals, both external and internal, was normal although the ceca and kidneys of the Myrj 45 group were somewhat enlarged. Microscopic studies demonstrated the absence of pathology in the following organs: liver, kidney, duodenum, ileum, and cecum. The lack of harmful effects upon feeding polyoxyethylene (8) monostearate (Myrj 45) to hamsters at dietary levels as high as 20% confirms the conclusion reached by other investigators working with man as well as with experimental animals, that no hazard may be expected from the proposed use of this emulsifier to the extent of a few tenths of 1% in the human diet.
