This study presents the optimization of machine parameters, development and evaluation of Pearl millet (Pennisetum glaucum) flakes using various processing treatments and their effect on polyphenolic contents and sensory parameters. A roller flaking machine was used with a throughput capacity of 350 kg/h. As the roller clearance increased from 0.1 to 0.5 mm, the length and width of flakes decrease from 5.2 to 3.09 mm and 4.44 to 2.76 mm respectively, whereas the thickness of flakes increased from 0.50 to 1.50mm. The bulk density of flakes was found proportional with the roller clearance ranged between 349.5– 590.7 kg/m3 at the mean moisture content of 8.11±0.07 per cent. Soaking with steaming treatment produced flakes with least bulk density 355 kg/m3. Steaming of grains resulted in flakes with optimum bulk density and textural parameters. Pressure cooking method resulted in the highest loss of total polyphenolic content.
