Milling behavior of hulled barley and its thermal and pasting properties
2010
Sharma, Paras | Gujral, Hardeep Singh
Eight commonly grown Indian hulled barley cultivars were studied for their dehusking, pearling, physico-chemical, β-glucan, pasting and thermal behavior. Milling of the hulled barley at 14% moisture significantly lowered the dehusking and pearling time as compared to milling at 10% moisture content. The extraction rate ranged from 55.05% to 62.35% and significantly (p <0.05) differed among the cultivars. Particle size distribution of flours was significantly different among the cultivars with flour from RD-2552 and RD-2035 cultivars having the most even particle size distribution. The colour difference (ΔE) was not significantly different among cultivars. The extractable β-glucan content varied from 1.93% to 3.81% among the cultivars and was highest in PL-172. The final pasting viscosity was significantly different among cultivars while the pasting temperature did not vary significantly. The enthalpy (ΔH) of gelatinization of barley flour varied from 4.45 to 7.08J/g and gelatinization temperature (Tp ) varied from 64.23 to 66.26°C.
