Four different dehulling equipments namely, burr mill, Victor millet mill model-I, Victor millet mill model-II and rubber roll sheller were tested for dehulling raw kodo millet by varying initial moisture levels of millet (9.0 to 10.1%). Among the four tested equipments, Victor millet mill model-II was found to be best for dehulling kodo millet with better dehusking efficiency (82.46 – 85.60%), milling recovery (57.05 – 57.71%), head yield (87.62 - 89.46%) and lower rice breakage (10.52– 12.37%). For polishing dehulled kodo rice, AVM Abrasive polisher was found to be suitable. Among various hydrothermal pretreatments attempted on kodo millet, soaking either in room temperature water for 24 h or in hot water (75°C for 3½ h) followed by steaming @1 kg/cm2 pressure for 15 min resulted in higher dehulling efficiency, head rice yield and milling recovery with least rice breakage. Storage study of unpolished and polished (@ 4 and 8% levels) kodo rice samples was done at ambient conditions for 60 days using different packaging materials such as polypropylene (300 gauge), stainless steel container, spun bound nonwoven bag and HDPE woven bag. Nutritional and cooking quality analyses of stored millet rice indicated that with storage, swelling index and cooking time increased but solid loss decreased. The cost of processing kodo millet into polished rice was Rs 1.65 per kg and the Cost: Benefit Ratio of processing was 1:1.88.ennullThesis
