All extruded products were air-dried in an oven at 50 C until a
moisture content of 6 g 100 g1 was reached, this moisture level
being considered adequate for texture evaluation. Axial expansion,
specific volume (SV), specific mechanical energy consumption
(SMEC), in J g1, was determined according to González, Torres, and
De Greef (2002).
Sample was milled using Ciclotec mill (UD Corp Boulder
Colorado-USA) using a 1 mm sieve. Water solubility was determined
according to González et al. (2002). Water absorption (WA)
was determined using Bauman method and expressed as ml of
water/g of sample
