Abstract
The effect of package material, physical form, and storage time on colour, viscosity and moisture content of solar-dried okra ( Hibiscus esculentus) during storage was studied using two packaging materials (polyethylene and cotton), two physical forms of solar-dried okra (unmilled (whole) and milled (powdered)), at weekly intervals over a 6 week storage period. Results showed that package material and storage time significantly ( P ≤ 0.01) affected all quality parameters monitored. The effect of physical form was significant ( P ≤ 0.01) only on the colour ( L ∗ and a ∗ values) of the products. The combined effect of packaging material and storage time significantly ( P ≤ 0.01) affected colour ( a ∗ values) and moisture content. Changes in moisture content of solar-dried okra was noted to affect, and most times highly correspond to changes in, some quality parameters. Overall analysis showed that powdered dried okra kept in a polyethylene package survived storage best.
