Analysis of Physical and Chemical Composition of Sweet Orange (Citrus sinensis) Peels

Sweet orange is one of the most common fruits in the World. The waste generated from the fruits needs to be put into a beneficial use. In this study some physical and chemical properties of the primary waste of sweet orange was investigated. The result showed sweet orange rinds (peels) as the major waste and contains 45-50% of the total mass of sweet orange fruits. The chemical analysis showed sweet orange rinds to be rich in protein of 7.15% and crude fibre of 12.79% which can be used as ingredients in processed food.
