Original Paper


Four Horse gram varieties GPM-6, Hebbal Hurrali-1, BHK and Paiyur-2 from southern region of India were studied for various physical, mechanical, aerodynamical and cooking properties. These parameters were often utilized to design and develop more economical and efficient agricultural produce processing machinery and equipment especially during post-harvest operations and for consumer accepatance. Length, width, thickness and volume of the horse gram varieties were in the range of 5.44–6.01, 3.99–4.09, 2.21–2.29 and 25.57–29.48mm3, respectively. Moisture content, thousand kernel weight, bulk density, true density, and porosity were in the range of 10.13–11.63%, 30.32–32.98 g, 810–901, 1250–1426 kg/m3, 34.92–36.87% respectively. Angle of repose ranged from 22.73 to 25.42°. The shape of individual grain was ellipsoidal. The experimental terminal velocity was greater for all varieties in comparison to its theoretical terminal velocity. Results showed that the soaking prior to cooking leads to reduction in cooking time for the horse gram varieties. A strong significant negative correlation of soaking duration with cooking time (r = −0.912, p < 0.01) was observed. Horse gram cultivars with low seed weight had higher cooking time and higher water absorption capacity. Among the varieties studied, GPM-6 was found to be the best followed by Hebbal Hurrali in terms of lower cooking time, higher water absorption of soaked seeds and low hardness of cooked seeds.
