“…As was anticipated, bambara groundnut seeds were found to contain both tannins and trypsin inhibitors ( Table 7). The presence of these two anti-nutritional JFA 60 1972;Poulter and Caygill 1980;Poulter 1981;Martino-Ferrer and Ferrer 1983;Liener 1989). It has been proposed that the trypsin inhibitors contain both heatlabile (protein) and heat-stable (tannin) fractions and, thus, it is possible that a proportion of the trypsin inhibitory activity measured in this study is accounted for by the tannin components (Poulter 1981).…”

Bambara groundnut seeds, produced under five levels of irrigation (0-300 mm range) in a suite of controlled-environment glasshouses, were analysed for their proximate composition. There was no significant effect ofwater treatment on the seed composition. Mean values (g kg-I DM) of dry matter, protein, starch, free sugars, non-starch polysaccharides and lipids were 8.91, 2.53, 4.28, 0.15, 2.56 and 0.79, respectively. Bambara groundnut protein was deficient in the sulphur amino acids, methionine and cysteine but met the FA0 requirements for all other essential and non-essential amino acids. Of the non-starch polysaccharides (NSP) of bambara groundnut, the ratio of insoluble to soluble fractions was 57:43.Cellulose accounted for 36% of the total NSP. Approximately 12.8% of the total NSP was resistant to acid and enzymic hydrolysis. This fraction was attributed to lignified seed coat material and low molecular weight phenolic compounds. Tannin complexes capable of precipitating 142.6 g BSA (bovine serum albumin) per kg seed and trypsin inhibitor activity (13 g kg-' DM) were measured in all five bambara groundnut treatments. The presence of these anti-nutrients may have implications for the bio-availability of bambara groundnut protein.
