Garbanzo bean and pea flours originating from the central part of the
cotyledons were higher in starch but lower in protein and fiber than t
hose from the outer layer of the cotyledon. These flours were fraction
ated by the wet process into prime starch, tailing starch, and soluble
s. The patented wet-fracionation method was successfully modified to r
educe the total amount of water during the process. The modified proce
ss produced comparable yield and purity of separated fracions. Under t
he recycling water method, the yields of prime starch were 46.7, 33.6,
and 41.1%, respectively, in garbanzo bean and two smooth pea cultivar
s (Latah and SS Alaska). Isolated prime starches were <0.4% in protein
and <0.19% in ash, indicating high purity.
