Generally, these food-stuffshavebeenrejectedbecauseofpoortasteandhavenotparticipatedintheusualdietarypatternbut,ifupgraded,perhapstheycouldbeincorpor-atedintohumannutrition.Amongtheindustrial-izationtechniquesavailabletoachievethesegoals,extrusion has been widely used because itssimplicity low cost (Smith, 1976; Kinsella,1978; Bastos & Areˆas, 1990; etal., 1991;Batistuti 1991; 1992; Caˆndido C 1993;Dodoketal.,1993;Attiaetal.,1994).Ithasbeenshownthatitcanalsobetexturizedandprovideahighly acceptable product (Batistuti etal.,1991).Bovine lung, in spite its great nutritionalpotential, experienced a strong aestheticrejection, mainly associated intrinsic lowtextural quality, however it shown thatitstexturecanbeimprovedbyextrusion(BastosA 1992;Campos&Areˆas,1993).Although generallyhigh,theacceptabilityoftheseextrudedproductswasfarfromthatoftraditionalcommercialones.Extruded chickpea bovine lung mixtures onthe other hand, produced comparable interms sensory brands,but superior (Cardoso-Santiago&Areˆas,2001).
