Abstract

5 var. of Bengal gram dhal flour were analysed for proximate composition, free and bound lipid, free fatty acid (FFA) content, peroxide value (PV) and thiobarbituric acid (TBA) value after storing the raw, roasted and puffed flours in 500-g capacity press-on lid cans for 48 wk at (i) 37 degree C or (ii) room temp. (20-25 degree C). Bound lipids formed 31.44% of the total lipids; free lipids decreased by 15-18% during roasting and puffing, with an increase in bound lipids. At the end of storage, the FFA content of raw flour stored at (i) and (ii) was higher (max. 10.8%) than in roasted and puffed flours ( less than 4%). PV (m-equiv. peroxide/kg oil) reached max. (18-21) in 16 wk in stored raw flours, but in roasted flour the PV was lower (19). In puffed flours max. PV (12) was reached after 16 wk of storage and it decreased to 5 and remained constant during the remaining storage period. TBA values were slightly higher in roasted and puffed flours during the 48 wk storage period.
