Evaluation of the Variation of the Contents of Anti-Nutrients and Nutrients in the Seeds of Legumes

Abstract

It is assumed that the content of anti-nutrients in legumes seeds

Chemical composition of leguminous seeds: part I—content of basic nutrients, amino acids, phytochemical compounds, and antioxidant activity

“…A strong correlation (P < 0.05) was observed in this study between the tannin content and protein level in the blue lupine, yellow lupine, Andean lupine, lentil, grasspea, and broad bean (+) and in the white lupine and pea (−) ( Table 5). Similar amounts of these anti-nutritional compounds in legume seeds were reported by Księżak and Bojarszczuk [28] in their investigations covering a very large area of Poland. They did not observe a significant effect of the site of cultivation on the tannin level, but correlated it with the species and cultivar.…”

Chemical composition and in vitro digestibility of some selected under-utilized tropical seeds as protein sources in ruminants’ diet

“…The three processing methods implored in this study lowered the antinutrients to a tolerable level that can easily be degraded in the rumen, if fed to ruminants as a feedstuff/ingredient in a complete concentrate diet, and thus nutrient absorption (vitamin D, iron, calcium and phosphorus) and general growth performance would not be hindered. The quantity of tannin of the roasted and soaked seed samples was lower than 5% that was reported to adversely affects dry matter intake and digestibility in ruminants (Księżak and Bojarszczuk 2014). Consequently, the astringent taste may lead to more water consumption by the animals, if fed.…”

Analysis and correlations of the protein content and selected ‘antinutrients’ of faba beans (Vicia faba) in a German sample set of the cultivation years 2016, 2017, and 2018

“…In the literature, a negative relationship between total PC and tannin content has already been mentioned for legumes. [31][32][33] However, in some studies a positive correlation (with no significance) was observed as well, 34,35 but there are also several studies that did not show any correlations between the PC and tannin content in legumes. 24,25 It is conspicuous that no research group appears to have questioned the exact causality of their results so far.…”

“…This is especially important for livestock feeding as seeds are often simply fed raw to the animals. In the literature, a negative relationship between total PC and tannin content has already been mentioned for legumes 31‐33 . However, in some studies a positive correlation (with no significance) was observed as well, 34,35 but there are also several studies that did not show any correlations between the PC and tannin content in legumes 24,25 .…”
