Nutritional study of new variety of groundnut(Arachis hypogaea L.) JL-24 seeds

摘要

Proximate composition, anti-nutritional and nutritional value of seeds of new variety of groundnut (Arachis hypogaeaL) JL-24 was determined. The result showed that the groundnut seed contain moisture (5.529%), crude fibre (1.149%), lipid (46.224%), crude protein (25.20%), carbohydrate (21.26%), ash (2.577%), calcium (0.087%), phosphorus (0.29%) and energy (601.856%). The total fatty acid composition was 10.44 and 33.51% for saturated and unsaturated fatty acid, respectively. The protein solubility at different pH ranging from 0.5 to 13.5, the maximum seeds proteins were extracted at pH 12. The serine has not been reported in the seed protein and the seed was found to contain highest amount of proline (6.412%). The anti-nutritional analysis shows that cyanide content 4.818 HCN/100g, tannin 0.412 g/100g, oxalate 0.180 g/100g and haemagglutinin activity for goat blood group is 1:8 and no haemagglutinin activity for chicken and human blood group, and no trypsin inhibition was found. The nutritive values were determined in terms of feed utilization 6.552%, nitrogen utilization 0.2957%, protein efficiency ratio (PER) (+) 1.368% and feed efficiency ratio (FPR) (+) 0.345%. The knowledge of this study could be utilized for various food preparation and selection for breeding purpose.Key word:Arachis hypogaeaJL-24, chemical composition, nutritional and anti-nutritional composition.
