Aims of this study were assessed the protein content of dry meat, raw egg, dehulled seeds of wheat, pigeon pea and study effect of concentration 1, 2 and 3% of the Pure Tannin, Solenostemma argel, Artemisia herba alba, Process green tea and Moringa oleifera on in-vitro protein digestability of animal and plant protein. Experiment: It was carried out in lab of Department of Food Science and Technology, Faculty of Agriculture, University of Khartoum in 2014. Methodology: Micro-Kjeldhal method and in-vitro protein digestability were used. Results: Results indicated that protein content of dry meat (77%) and raw egg (79%) was higher than protein content of dehulled seeds of wheat (18%) and dehulled seeds of pigeon pea (22%). There was significant difference between the four samples in protein at P ≤ 0.05. In-vitro protein digestability of dry meat, raw egg, dehulled seeds of wheat and pigeon was clearly reduced with increasing the concentration of pure tannin. While in-vitro protein digestability for dehulled wheat was clearly increased with increasing the concentration of S. argel leaves, but no significant was observed in dehulled seeds of pigeon pea, but at concentration 3% S. argel, the in-vitro protein digestability was decreased. In case of dry meat and raw egg in-vitro protein digestability was reduced with adding 1, 2 and 3% S. argel leaves. Whereas, in-vitro protein digestability for dehulled seeds of wheat was improved with increasing concentration of S. argel, but in-vitro protein of dehulled pigeon pea was decreased with increasing concentration of S. argel. While in-vitro protein digestability for dry meat, raw egg, dehulled seeds of wheat and pigeon pea was reduced with increasing concentration of A. herba alba, process green tea and M. oleifera, but at concentration 3% of moringa the in-vitro protein digestability of dehulled seeds of pigeon pea (75%) was improved. Conclusion: Protein content is very rich in animal products, but it is very poor in plant products. Uses of S. argel with dehulled seeds of wheat was improved its in-vitro protein digestability, but uses of pure tannic acid, A. herba alba and green tea reduced in-vitro protein digestability.
