Boiling influences the nutritional value of three seed cowpea (Vigna unguiculata) varieties using in vivo and in vitro methods.

This study aimed to evaluate the effect of boiling seeds of three cowpea (Vigna unguiculata) varieties on nutrient ileal and total tract digestibilities in rats and in vitro hindgut production of short-chain fatty acids (SCFAs). Boiling influenced nutrient ileal and total tract digestibilities, and production of SCFAs (P < 0.05), but its effect was in general cowpea specific.

Heating and Soaking Influence in Vitro Hindgut Fermentation of Tropical Legume Grains in Pigs.

The effects of different thermal (raw versus autoclaving or boiling for 5 and 20 min) and soaking (with or without) treatments on the in vitro hindgut fermentation in pigs of undigested residue collected after in vitro foregut digestion of tropical legumes' grains (Canavalia brasiliensis; Lablab purpureus; pink, red and white Vigna unguiculata) were investigated. The undigested residue was fermented with a pig fecal inoculum to determine fermentability, gas, and short-chain fatty acid (SCFA) productions. Soaked raw legumes increased the production of SCFAs (e.

The impact of heating and soaking on the in vitro enzymatic hydrolysis of protein varies in different species of tropical legumes.

The effects of different thermal (raw, autoclaving or boiling for 5 and 20min) and soaking (with or without) treatments on the degree of hydrolysis (DH) of protein were investigated for selected legumes (Canavalia brasiliensis; Lablab purpureus; pink, red and white colour hulls Vigna unguiculata). Each legume preparation underwent in vitro simulated gastrointestinal tract digestion comprising either pepsin (120min) or pepsin/pancreatin (120/240min) digestion. The DH was determined based on the amount of free amino groups released.
