Analysis of the Proximate and Mineral Contents in Uziza (Piper guineense) Seeds from Three Different States (Ebonyi, Cross-River and Delta) in the Southern Part of Nigeria

摘要

Studies were carried out to determine the proximate and mineral contents in Uziza seeds from three different states (Ebonyi, Cross-River, Delta) in the Southern part of Nigeria using established standard laboratory procedures. ANOVA showed that the proximate and mineral contents of uziza seeds in the three state of study differ significantly at p < 0.05. Of the three states, the proximate and mineral contents of the plant seeds from Ebonyi was the highest in crude protein, ash, dry matter, Mg, Zn, Fe, Cu, Na, K and Ca with values of 12.62%, 16.33%, 0.14ppm, 0.33ppm, 0.57ppm, 0.08ppm, 0.80ppm and 0.94ppm respectively. The plants seeds from Cross-River was the highest in carbohydrates, moisture content, crude fibre and crude fat with values of 54.31, 9.17, 13.61 and 11.04% respectively. The mineral compositions of the P.guineense seeds in the three locations decreased in the following order: K > Ca > Na > Fe > Zn > Mg > Cu. The seeds from the selected states contain the mineral elements in the following decreasing order: Ebonyi > Delta > Cross-River.
