Extraction and Characterization of Mucilage from Okra Fruit and Ogbono seed


The study involved extraction and characterization of mucilage from okra fruit (Abelmoschus esculentus) and ogbono seed (Irvingia gabonensis). Both samples were purchased from Ekwulobia market, Aguata L.G.A., Anambra State. Mucilage extraction was carried out using conventional method following standard procedures of maceration followed by precipitation using ethanol. The extracted mucilages were characterized using standard methods. The percentage yield of mucilage from okra fruit and ogbono seeds were 11. 65 and 14.62 % respectively. The properties of the extracted okra fruit and ogbono seed mucilages evaluated were respectively: pH (5.7 and 5.9), viscosity (1.5 and 22.8 mPa?s), true density (1.06 and 2.85 gm/ml), water holding capacity (3.41 and 4.35 gH2O/g dry mucilage), oil-holding capacity (2.16 and 2.42 g/g). Both mucilages were soluble in hot water but insoluble in ethanol and acetone. The results of the phytochemical analysis for okra fruit and ogbono seed mucilages were respe
