Safeguarding Edible Mushrooms from Southwest Burkina Faso: A Documentation of their Ecology, Traditional Uses, and Nutritional Value
- Asian Journal of Science and Technology , 13 : 32-38
Résumé
Wild edible mushrooms are vegetables proteins sources used for centuries with appreciate nutritional and medical properties This study aimed to characterize common popular mushromms in Southwest region (Burkina Faso) and determine their nutritional value. A field survey combined with interviews was carried out with 225 people for the collection of relative data. Standards methods was used for proximate compound analysis, minerals content, ascorbic acid and beta caroten determination. The results indicate that Cantharellus sp, Candolléomyces sp, Russula sp are popular mushrooms speces in this area. Harvesting is more abondant between jully and september and dried and smoked are the main preservation process. Proximate composition (g/100g) showed appreciate values of moister content (7.54±0.09 to 8.48 ±0.06), acidity (5.94±0.00 o 49.05±0.33), crude proteins (23.03±0.38% to 36.77±0.3), lipids (2.25±0.04 to 2.69±0.4) carbohydrates (24.797±0.59 to 28.78±0.7), fibers (26.39±0.58 to 46.70±0.55), ash (11.22±0.47 to 25.03±0.27), and energy (213.20±2.75 to 286.83±3.50 kcal/100g). Beta-carotene content was ranged from 0 to 4.260±0.04 mg/100g (Candolléomyces sp), while ascorbic acid (Vitamin C) content varied from 0.103±0.02 mg/100g (Candolléomyces sp) to 0.256±0.00 mg/100g (Cantharellus sp). Minerals content (mg/100g) showed a content of K (1476 to 2830), Mg (46.93 to 194.03), Na (20.5 to 49.2) Ca (19.28 to 195.94), Zn (3.97 to 4.86), Fe (2.92 to 14.29). Mn (1.78 to 9.95) and Cu (1.14 to 3.89). Wild edible mushrooms have appreciated nutritional value, but only available during raining season. As they are treathened by both climate change and human activities. Initiatives to safeguard them may inculde either creating biobank or through domestication and demonstrating their detailed nutritional values and safety.
