Contents and digestibility of carbohydrates of ricebean and fababean as affected by simple inexpensive processing methods

Abstract

Ricebean (RB‐32) contained significantly (p < 0.05) higher amounts of total soluble (5.6g/100g) and non‐reducing sugars (5.0g/100g) than fababean (VH‐82‐1). On the other hand, the contents of starch and reducing sugars were more in fababean (53.2g/100g; 608.7mg/100g) than those in ricebean (50.7g/100g; 547.3mg/100g). The starch digestibility (mg maltose released/g meal) of whole raw seeds and husk of ricebean and fababean was 30.8; 6.3 and 42.1; 6.3, respectively. Due to soaking, sprouting and dehulling, a significant (p < 0.05) improvement occurred in in vitro starch digestibility of both ricebean and fababean. Germination for 24 hours in ricebean and 48 hours in fababean was found to be the best as it could improve the starch digestibility to the extent of 100 to 90 per cent over the control.
