Evaluation of guar meal detoxification by bioassay with rat and tetrahymena pyriformis W

  • P. P. Khopkar

Attempts were made to detoxify guar meal by autoclaving and dilute acid extraction. Upgrading achieved was evaluated by proximate analysis. The extent of detoxification achieved by autoclaving and acid extraction was compared and evaluated by bioassay with male weanling Wistar rats andTetrahymena pyriformis W. Supplementation with tryptophan, methionine and threonine significantly improved the PER of the detoxified guar meal.
