Determination of chemical composition of Carob (Ceratonia Siliqua): protein, fat, carbohydrates and tannins

Carob pod, germ, and seed were analyzed for moisture, ash, protein, fat, carbohydrates and particularly for their tannins content. Recovery of tannins as affected by various solvent extraction systems was investigated. Carob pod meal contained high levels of carbohydrates, appreciable amounts of protein and low levels of fat. Germ and seed contained more fat and less carbohydrates. Seventy percent acetone was the most effective solvent for the exctration and recovery of tanniins.
