A process for the preparation of detoxified Simarouba glauca oilseed meal

Simarouba glauca, commonly known as Aceituno, is a tree-borne oilseed belonging to Simaroubaceae family. Simarouba forms an important source of edible oil (60%). Various anti-nutritional / toxic constituents like saponin (3.7%) and alkaloids (1.0%) gets concentrated in the simarouba meal during extraction of oil and renders the simarouba meal unfit for feed/food purposes. A simple and adoptable process is described, wherein detoxified Simarouba meal is obtained using steps like two-stage acetic acid boiling and Ethanolic acetic acid wash. Saponins were reduced by 94% and alkaloids by 91% in detoxified simarouba meal. The detoxified Simarouba meal contained high protein (~60%) with in-vitro protein digestibility value of 84-86%. Evaluation of efficacy of detoxification process of Simarouba meal was carried in rat feeding trials, which gave Protein Efficiency Ratio (PER) of 1.90, indicating the potential for their use in feed formulations.
