Proximate analysis and anti-nutritional factors in three varieties of groundnut (Arachis hypogaea)

Abstract

This study evaluated the nutritional qualities in seeds of three varieties of groundnut (SAMNUT-23, SAMNUT-24, and SAMNUT-26) as part of breeding lines undergoing genetic improvement at the Joseph Sarwuan Tarka University, Makurdi, Nigeria. From the result, the grand mean nutritional composition in groundnut seeds showed that lipid was the highest class of food (48.5%) followed by protein (22.7%). Others are carbohydrate (11.7%), moisture (8.6%) and ash (6.2%) while fibre content was the lowest (2.3%). Result indicated that SAMNUT-26 had the highest lipid (49.67%) and ash content (7.44%). SAMNUT-23 had the highest protein (24.45%) and SAMNUT-24 had the highest carbohydrate (15.94%) and moisture (8.73%), there was no significant difference among the varieties (P>0.05). Cyanide was not present in the three varieties studied while phytic acid was present as anti-nutrient but in small quantity with insignificant varietal differences (P>0.05). Oxalate content was the highest anti-nutrient obtained and it did not differ significantly among the varieties (p
