Abstract
This work is concerned with the enrichment of peanuts by the addition of two plants that is, avocado seed (Percea Americana) and rice grains (Oryza sativa) into the coating of the peanuts. These two underutilized seeds were processed (cleaned, sliced, washed, sun-dried, milled, cooled, sieved and packaged) into fine flour and incorporated into the peanut with other ingredients. The proximate compositions, functional compositions and sensorial acceptability of the peanut coated with rice-avocado seed composite flour were determined. The proximate composition showed that the ash content ranged from 0.71–2.84%, moisture content 1.86– 6.99%, crude fiber 3.46% - 8.41%, fat content 25.37% - 47.54%, crude protein 25.38% - 34.12%, carbohydrate content 14.79% - 27.87% and energy value ranged from 1993.67– 2463.44KJ/100g. The functional composition showed that water absorption capacity ranged from 0.92g/g– 2.02g/g, oil absorption capacity 1.09g/g– 1.88g/g, bulk density 0.67 g/g– 1.05g/g, emulsion capacity 39.62% - 41.67%, foaming capacity 5.00% - 10%. However, the sensory evaluation revealed that all the samples had no significant difference in taste, texture and overall acceptability. There is a significant difference in colour and aroma. Sample AOB (100% rice flour) was preferred over other samples....
