Title : Evaluation of the Minerals, Proximate, Viscosity and Antinutrients of the Fruits of Corchorus olitorius Accessions
by SAMUEL OLORUNFEMI BAIYERI, CHIMALUKA CHINELOROMMA AJOKE SAMUEL-BAIYERI,
Abstract : In spite of the huge nutritional benefits of Corchorus olitorius leaves, documented knowledge and information on the food value, viscosity, nutritional and anti-nutritional contents of its fruits are scarce in the literature. Fresh and tender fruits of five Corchorus olitorius accessions were analysed for their minerals, proximate composition, viscosity and antinutrients in order to unravel their nutritional and anti-nutritional compositions thereby creating awareness about their dietary potentials. Results showed that the proximate, minerals, viscosity and antinutrients in the fruits were significantly (p<0.05) affected by accessions. The potassium was in the range of 485.0-647.5 mg/100 g, iron 4.62-7.22 mg/100 g, calcium 738.2-1187.5 mg/100 g, zinc 4.06-4.14 mg/100 g, copper 0.20-0.23 mg/100 g, magnesium 105.75-113.85 mg/100 g, manganese 1.74-4.48 mg/100 g and phosphorus 46.25-73.60 mg/100 g. The fresh Corchorus fruits were comparably lower in antinutrients than what has been found in most of the commonly consumed vegetables. Pearson’s correlations among proximate qualities and minerals showed that crude protein showed a positive and significant (p<0.01) correlation with zinc (0.92**). Dry matter had a very strong significant and positive correlations with carbohydrate (0.95***) and manganese (0.79*). Calcium showed significantly positive correlations with zinc (0.68*), iron (0.76*) and potassium (0.62*). Magnesium showed a very strong and significantly positive correlations with zinc (0.77***) and phosphorus (0.93***). Results revealed fresh Corchorus olitorious fruits are more nutrient-dense than the leaves and seeds. The results have revealed Corchorus olitorius fruits are low in fat, calories and antinutrients are nutrient-dense and could help in combating malnutrition, especially micronutrient deficiencies.
