“…The differences between different soya bean cultivars as well as between them and cowpeas may be due to environmental differences in the areas of cultivation. 29 Cold soaking did not reduce trypsin inhibitor activity in the PM (Table 3). This agrees with the findings of Wang et al 30 and Ogun et al, 4 who concluded that cold soaking was not an efficient method because it did not eliminate trypsin inhibitor activity.…”

Analysis was done of the composition and bioactive factor content of whole meal, processed meal and protein concentrate from a cowpea cultivar (Vigna unguiculata L. Walp var. IT86D-719) grown in Yucatan, Mexico and of changes in these parameters after soaking and dehulling. Both meals had a high protein content (247.53 and 257 g kg −1 dry matter (DM) respectively). The protein concentrate was rich in protein (786 g kg −1 DM) and lipids (58.47 g kg −1 DM) and had an amino acid profile similar to that of the processed meal. The amino acid profiles of the meals almost covered human dietary requirements based on FAO/WHO/UNU-suggested profiles but were deficient in sulphur amino acids. Trypsin inhibitor activity was high in both meals compared with levels found in previous studies. Trypsin inhibitor activity in the concentrate was not eliminated but was significantly reduced. Lectin activity, tannin levels, phytate levels and α-amylase inhibitor activity were relatively low in the meals, and cyanogenic glucosides were not detected. Residual amounts of α-amylase inhibitors, tannins and phytate were observed in the concentrate, and lectin activity was not detected. Results indicate that V. unguiculata L. Walp var. IT86D-719 meals and protein concentrate are good potential foodstuffs in the Yucatan region.

“…However, Taylor et al (2002) have shown that chemical composition can vary among different accessions of fenugreek originating from different countries of the world, as well as for plant lines grown at three different sites in western Canada over a 2-yr period. Variation in genetics and environmental response of plants to production of phytochemicals also has been shown for the Australian sweet lupin (Lupinus angustifolius), the Nigerian cowpea [Vigna unguiculata (L.) Walp], the Hawaiian kava (Piper methysticum Forster), and Capsicum annum L. (Ruiz et al 1995;Oluwatosin 1999;Lebot et al 1999;Zewdie and Bosland 2000).…”

“…and anti-nutrients content. Oluwatosin (1999) and Nikolopoulou et al (2006) found that the variability in the levels of some antinutritional factors (i.e. tannins and phytic acid) in chickpea and cowpea seeds depends largely on the environment where they are grown.…”

Experiments were conducted in open field to assess the effect of seeding season and density on the yield, the chemical composition and the accumulation of total tannins in grains of two chickpea (Cicer arietinum L.) cultivars (Pascià and Sultano). Environmental conditions and genetic factors considerably affected grain yield, nutrient and total tannins content of chickpea seeds, giving a considerable range in its qualitative characteristics. Results confirmed cultivar selection as a central factor when a late autumn-early winter sowing is performed. In effect, a more marked resistance to Ascochyta blight (AB) of Sultano, allowed better agronomic performances when favourable-to-AB climatic conditions occur. Winter sowing appeared to be the best choice in the Mediterranean environment when cultivating to maximise the grain yield (+19%). Spring sowing improved crude protein (+10%) and crude fibre (+8%) content, whereas it did not significantly affect the accumulation of anti-nutrients compounds such as total tannins. The most appropriate seeding rate was 70 seeds m -2 , considering that plant density had relatively little effect on the parameters studied.
