Abstract
This study was conducted to compare the proximate composition and some antinutritional factors of treated and untreated Jatropha Curcas Kernel Cake(JKC).Standard procedures were employed to analyse the samples of dried seeds of Jatropha curcas purchased from open market. Results showed that after solid state fermentation with Absidia spinosa, the treated JKC contained 52.50% crude protein, Mucor rouxii treated JKC contained 52.10% crude protein. Treatment of JKC with the mixed culture of Absidia spinosa and Mucor rouxii yielded 53.20% crude protein. Tannin content of the raw, toasted, Absidia spinosa treated, Mucor rouxii treated and those treated with the mixed culture of Absidia spinosa and Mucor rouxii were 4.80g, 3.81g, 3.53g, 3.40g and 3.34g respectively. Saponin and phytate contents also decreased when treated with various methods employed in this study. This preliminary study has shown that the methods of detoxification employed in this study have potentials to improve the nutritive value of JKC and also to reduce appreciably some of the Antinutritional factors present in the raw, unprocessed cake.
