The objective of this study was to determine the effect of duration of cooking of various varieties of Lablab purpureus beans at 1000 on their antinutritional factor compositions. Nine different varieties of Lablab purpureus beans were subjected to cooking for 0.0, 10.0, 200, 30.0), 40.0,50.0 and 60.0 minutes respectively at 100°C. For each batch of cooking, 4 litres of water was first brought to boiling in a 10 litre aluminium cooking pot and about 50g of the seed was poured into the boiling water, covered and allowed to cook for each specified time period. The seeds were sun dried for 3 days before milling. A representative sample for each cooking time and for each variety was taken to the laboratory for the determination of antinutritional factors to include trypsin inhibitors, phyric acid, tannin and hydrocyaric acid. Results obtained indicate that duration of cooking had a significant (P<0.05) effect on the antinutritional composition of the various varieties of lablab beans. The levels of antinutritional factors in the beans were found to decrease significantly (P<0.05) as the duration of cooking increased across the various varieties. However percent destructions of trypsin inhibitor activity, phytic acid and hydrocyanic acid were very rapid at about 30 minutes of cooking.

Ileal digestibility of protein and amino acids was measured in pigs fed 13 round, tannin-free peas samples and related to the following physical, chemical and biological characteristics of these samples: thousand-seed weight, proportion of hulls, starch, fibre, crude protein, ether extract and ash contents, trypsin inhibitor activity and trypsin inhibitor activity per unit of crude protein (TIAP). Each pea sample was included in a diet containing starch, sucrose, minerals and vitamins and fed to four barrows (50 to 100 kg) fitted with an end-to-end ileo-rectal anastomosis. Standardised ileal protein and amino acid digestibilities, except for alanine of peas decreased linearly with increasing TIAP (P < 0.01) and was not affected by fiber content. For example standardized ileal digestibilities values (%) decreased by −0.1975, −0.1617, −0.2171, −0.2630, −0.2029 and −0.3536 per unit of TIAP (expressed in unit of trypsin inhibited per milligram crude protein), respectively, for crude protein and lysine, threonine, methionine, cystine and tryptophan. Key words: Peas, trypsin inhibitor activity, standardised ileal digestibilities, protein, amino acids, pig
