ABSTRACT

Samples of groundnut, millet, wheat, guinea corn and breadfruit were analysed for proximate chemical composition, phytotoxins, mycotoxin, mineral and trace elements. The investigation showed that the samples contained 8.00 ± 0.62 - 11. 98 ± 0.54% moisture, 8.73 ± 0.92 - 26.9 ± 1.42% protein, 1.27 0.27- 48.82 ± 1.62% fat, 0.91 ± 0.24-6.92 ± 1.32% crude fibre, 1.64 ± 0.13-3.06 ± 0.43% ash, 6.11 ± 2.56 - 75.73 ± 1.76% CHO; Phytotoxin contents were 0.60 ± 0.06-1.24 ± 0.08% alkaloid, 0.82 ± 0.13-2.27 ± 0.55%falconoid, 0.03 ± 0.02 - 0.05 ± 0.03% saponins, 0.50 ± 0.06 - 0.60 ± 0.03% tannins, 2.40 ± 0.34-2.80 ± 0.08% phenols, U.17 ±0.04 -0.30 ± 0.03% phytic acid, 4.83 ± 0.18- 8.42 ± 0.35% HCN. Vitamin contents were 0.36 ± 0.03-29.97 ± 1.09 iu/kg vitamin A, 8.80 ± 0.60 - 28.60 ± 0.64mg/bOg vitamin C, 0.54 ± 0.07 - 17.38 ± 0.50mg/bOg Niacin, 0.09 ± 0.02-0.90 ± 0.04mg/ bOg Thiamin, 0.07 ± 0.03 - 0.18 ± 0.03mg/bOg Riboflavin. Samples were rich of mineral and trace elements contents; Ca, Mg, Na, K, P, Fe, Cu, Zn, Ni, and V.Trace heavy metals; Pb, Cd, As and Hg, were of safe limit. Samples contained 19.00 ± 1.17 - 78.21 ± 292.ig/kg Aflatoxin Bi ,therefore, prolonged consumption of large part of the samples may constitute a public health hazard.
