Sk. Singh et al., EFFECT OF SODIUM-HYDROXIDE, CALCIUM HYDROXIDE, AND POTASSIUM HYDROXIDE ON DEBRANNING OF CORN, Cereal chemistry, 74(3), 1997, pp. 254-257
The effect of sodium hydroxide, calcium hydroxide, and potassium hydro
xide, and processing conditions (alkali concentration and soaking time
) on corn debranning was studied at a temperature of 55 degrees C. Fib
er yield, soluble dry matter loss, and total dry matter removed were d
etermined for different alkalies and processing conditions. Sodium hyd
roxide and potassium hydroxide resulted in maximum fiber yields of 3.3
8 and 3.48%; maximum soluble dry matter loss of 7.63 and 10.96%; and m
aximum total dry matter removed of 10.52 and 13.26%. Calcium hydroxide
at 6% concentration level resulted in negligible fiber yield, soluble
dry matter loss, and total dry matter removed with soak times up to 1
6 hr. Sodium hydroxide has higher debranning action than potassium hyd
roxide at 3 and 6% concentration levels; whereas, at 9% concentration
level, potassium hydroxide has higher debranning action.
