Abstract:
Background and Objective: Staple food remain the major source of foods in Nigeria and West Africa. However, due to challenge of diseases, there have been a lot of setbacks in its farming and processing. This study investigated if application of fungicide affects nutritional composition of Colocassia esculenta (cocoyam). Materials and Methods: Fungicide was applied foliarly and farming season lasted for 8 months. All farming conditions for proper growth of the cocoyam were achieved. At the end of farming, amino acid analysis, phytochemicals and nutrient composition were determined using standard protocols. Results: Result obtained showed reduced phytocompounds in the control group when compared to the test group treated with the fungicide. Alkaloid (1.72±0.55, 3.07±0.18), flavonoid (3.96±0.95, 4.31±0.03), Tannins (0.65±0.22, 0.17±0.05), saponin (1.81±0.01, 3.00±0.05), Glycoside (5.26±0.10, 9.23±0.20), oxalate (0.58±0.03, 1.98±0.16) and phytate (0.31±0.03, 1.51±0.10) in control and test group respectively. Result for proximate composition showed reduced crude fibre (3.43±0.24, 1.12±0.07), starch (20.33±0.32, 15.50±0.57), amylose (6.72±0.16, 4.97±0.09) and lipid content (1.85±0.28, 0.96±0.09), reduced vitamin content, reduced amino acid content and increased mineral contents in the group applied fungicide when compared to control. Conclusion: It could be concluded from the results obtained this study that the fungicide used, affected the nutritional and anti-nutrient composition of cocoyam.
