Abstract

This research effort aim at determining the effect of drying on the extraction of pectin from lemon peels. Two methods were used to extract pectin from lemon peels namely: the water base extraction method and the microwave extraction method. These methods were carefully carried out on both the fresh and the dry peels samples. First, the samples were washed, partially dried for the fresh peel and completely dried for the dry peel. Sulphuric acid was used in setting the pH of the solutions to 1, 2 and 3 in the water based extraction method while the use of Ethylene DiamineTetraacetic Acid (EDTA) and Sodium Hydroxide (NaOH) were used to set the pH to 1.5 and 10 respectively for the microwave extraction method. The solvent systems were then treated with the pectin samples at different times and temperatures to obtain varying results. The effect of time, temperature, pH and solvent systems were then studied and the yields obtained were recorded and compared. The results obtained shows that when a peel is completely dried using sun, it losses some amount of pectin probably due to thermal degradation of the pectin in the albedo resulting in pectin yield becoming small. The result also revealed that increase in acidity, extraction time and temperature increases the yield by a range of 0.01 to 0.50.
