dc.description.abstractThe evaluation of the n u t r i t i o n a l value of the seeds of Tetracarpidium conophorum (Mull, Arg,) Hutch & Dalza, which belongs to the family of Euphorbiaceae, was carried out on four d i f f e r e nt samples which include the raw, the cooked, the raw cotyledon and the raw cotyledon-removed kernels of the seed. The analysis shows that the raw seed kernel contains 35.49% moisture ( a t 60 C), 40.30% moisture ( a t 105 C) both of which were on fresh weight b a s i s . The dry raw sample contains 40.3% ash, 95.54% t o t a l organic matter, 49.16% crude f a t , 20,62% crude p r o t e i n (Kjeldahls method), 21.06% crude protein (Nesslers reagent method), 25.76% t o t al carbohydrate, 5.78% soluble carbohydrate and a c a l o r i f i c value of 627.96 k i l o c a l o r i e s per 100g of dry sample. The amino acid composition showed some of the e s s e n t i a l amino acids l i k e isoleucine, phenylalanine plus t y r o s i n e and methionine to be above the values recommended by FAO/WHO (1973). Tryptophan was destroyed on hydrolysis and threonine was no detected. The mineral elements determined in the raw seed sample were Cd: 2..26 ugg- 1 , Ca: 0.725%c, Cu: 20.11 Ugg , Fe: 0.030%, Ng: 0.106%, Mn: 0.010%, P: 0.86%, K: 1.6)4%, Nai 0.076% and Zn: 62.17 ugg-1 Cobalt was however not detected at the working concentration range employed. Cooking was found to have led to the d e s t r u c t i o n of Valine and a decrease in the concentration of other amino acids detected (with the exception of aspartic acid). It has also decreased the crude f a t , the soluble carbohydrate and the t o t a l c a l o r i f i c value in addition to a decrease in the concentration of a number of e s s e n t i a l n u t r i e n t elements. In p a r t i c u l a r , it decreased the concentrations of a number of antinutritional elements "by increasing the potassium to sodium and zinc to cadmium ratios from 21.58 to 33.78 and from 21.50 to 74.25 respectively. The cotyledon sample has proven to have a higher concentration of most of the nutrients than the other samples analysed. These findings were discussed in terms of the value of the nut as food for man and animals.en_US
