Technical
Objectives:
1. To study the physico-chemical properties of pigeon pea grains.
2. To study the effect of enzymatic pre-treatments on loosening of seed coat of pigeon pea grains and milling quality of enzyme treated pigeon pea.
3. To determine the effect of enzymatic pre-treatments on protein content of dhal.
4. To study the cooking quality of dhal
5. Establishment of pulse mill for demonstration purpose

Enzyme concentration calculationFor 100 gm pigeon pea
Drying of the treated pigeon peaAfter the completion of each incubation. Seeds
were dried in tray dryer at 550C and maximum up to 600C up to moisture content reached near to 10 % for the nullifying the effect of enzymes. After that easily seed coat were removed with the pinch of thumb and finger.
