摘　　要：The micronutrient compositions of stored cocoyam-based products were determined using gas chromatography and atomic absorption spectrophotometry.The dried cormels and dried cocoyam leaves were pulverized with a locally fabricated machine and stored in various plastic containers for 0,1,2,3 months.The data obtained were analyzed statistically using SPSS version 21.Means were separated at P≤0.05 using Fisher’s Least Significant Differences.The vitamin contents(mg/100g)of achicha were as follows:cocoindia had total carotene(1.84),B1(0.071),B2(0.044),B3(0.41),C(4.14)while edeofe had vitamin E(0.84)and total carotene(1.24),B1(0.021),B2(0.013),B3(0.18),C(2.47)and E(0.57)after storage.The vitamin contents(mg/100g)of mpoto were as follows:cocoindia had B1(0.53),B2(0.31),B3(1.75),C(18.46)and E(5.28)while edeofe had total carotene(3.44μg/100g)and B1(0.26),B2(0.14),B3(1.19),C(8.61)and E(2.46),and anampu had total carotene(2.56μg/100g)after storage.The mineral composition(mg/100g)of achicha are as follows:anampu had Ca(48.78),Na(18.52),Mg(10.18),Mn(0.17)and P(19.61),Fe(2.47),Zn(2.60),I2(51.71);edeofe had P(26.27),Fe(3.66),Zn(2.91),and Ca(40.53),Na(10.67),Mg(6.29),K(285.77),Mn(0.075);and cocoindia had K(405.87)and I2(69.34)after storage.The mineral compositions of mpoto(mg/100g)are as follows:anampu had Ca(157.57),Mg(95.84),K(485.52),P(45.52),I2(90.33)and Zn(2.61);edeofe had Fe(4.87),Zn(4.52),and Ca(152.29),Na(176.54),Mg(84.77),K(325.87),P(35.53),Mn(0.25),I2(65.29)and cocoindia had Mg(95.84),Mn(0.63)and Fe(3.61)after storage.Micronutrients of the products reduced significantly(P≤0.05)during storage.Fortified Colocasia products with micronutrients will meet the required recommended dietary intake.
