Production of Mucuna pruriens (var. utilis) Proteins Isolates Using Central Composite Design and Effect of Drying Techniques on Some Properties

Response surface methodology was used to model the effect of temperature, NaCl concentration and pH on the production of protein from Mucuna pruriens seeds. The analysis of response surface graphs showed that the optimal parameters correspond to a temperature of 27°C, a concentration of NaCl of 0 mol/L and a pH of 6. The water absorption capacity of the Mucuna protein isolates was 171°g and 124 g of water per 100 g of dry matter respectively for freeze-dried and spray-dried isolates. The granulometric distribution of emulsions was monomodale. The emulsion made with bottom proteins of Mucuna has presented a viscoelastic character.
