TWO WIDELY CONSUMED WILD MUSHROOMS FROM CENTRAL CÔTE D’IVOIRE: THEIR PROXIMATE ANALYSIS, MINERAL COMPOSITION AND AMINO ACIDS PROFILE
Journal Title: Annals. Food Science and Technology - Year 2016, Vol 17, Issue 1
Abstract
In central Côte d’Ivoire, wild mushrooms identified as Volvariella volvacea and Psathyrella tuberculata are collected during the rainy season and valued as a traditionally nutritious food by the population. However, their nutritional attributes have not been adequately studied. Hence, the objective of this work was to evaluate nutritive potential of these mushrooms picked in the wild in the three administrative regions of central Côte d’Ivoire through their chemical proximate composition, mineral and amino acids profiles. Moisture was estimated to 87% for samples of fresh V. volvacea and 90% for samples of fresh P. tuberculata. Carbohydrates were the predominant nutrient within all samples (52-53% for V. volvacea and around 56% of dry matter for P. tuberculata) followed by proteins (around 30% for all samples, whilst fats were the least occurring nutrient (2.27-3.20% for V. volvacea and 1.40-1.78% for P. tuberculata). Ash contents were around 11% for P. tuberculata and ranged from 13.80 to 14.70% within V. volvacea. Fibers were also analyzed with relatively high levels (around 8 % for all samples of V. volvacea and ranging in 12.97-14.04%) for samples of P. tuberculata). Suitable concentrations of biologically important minerals (microminerals: Fe, Mn, Zn, Cu and macrominerals: Ca, Mg, Na, K, P) were observed in all samples with slight variations from one sample to another. In contrast, all mushrooms samples displayed low concentrations of Pb and Cd. Amino acids profile demonstrated quality of proteins of all mushrooms since many essential amino acids (leucine, isoleucine, threonine Phenylalanine) were successfully investigated. Therefore, these species of wild mushrooms could represent great potentials in preventing protein and mineral deficiency in the regions of central Côte d'Ivoire.
