Evaluation of the chemical composition and sensory quality of parboiled local and imported milled rice varieties marketed in south-east zone of Nigeria

Rice imported into Nigeria is generally perceived to be of higher quality nutritionally than local rice which has caused low patronage and low market share for local rice. It is therefore essential to compare the nutritional composition and sensory quality of these local and imported rice varieties to verify the perceived claims. Eighteen local and 3 imported rice varieties coded Ip1, Ip2 and Ip3, were evaluated for...
