Studies on the extraction of polyphenolic compounds from pre-consumer organic solid waste

Waste disposal and treatment are some of the major problems faced in food processing industries, and improper disposal can cause damages to the environment along with adverse effect on human health. Since these wastes contain important biologically active compounds, they can effectively contribute to the production of value added products. The extraction of polyphenolic compounds from pomegranate fruit peel using different solvents with the assistance of non-ionic surfactant dimethyl sulfoxide was investigated. The maximum extract yield and total polyphenolic content obtained were 29.3 +/- 0.4 and 32.62 +/- 0.2%, respectively. The extracted polyphenolic compounds could be used for the manufacturing of many value added products.
