Abstract

Rapeseed oil is currently the third source of vegetable oils. Crude oils generally contain undesirable substances which need to be removed to produce a stable and edible product. So, rapeseed oil is subjected to industrial treatments such as extraction, degumming, bleaching, deodorization, and subsequently produces large quantities of byproducts like hull and fibers, rapeseed meal, rapeseed cake, deodorizer distillate, acid oil, soapstock, etc. If these byproducts are not used for any beneficial activity, they can harm the environment. At the same time, they can be a promising source of high-value products and uses. For example, rapeseed cake and rapeseed meal is a protein-rich ingredient widely used to feed all classes of livestock. Moreover, they can be used as fuel, biogas substrate or fertilizer, or a source of natural antioxidants. Soapstock usually uses in animal feed, biodiesel synthesis, and producing soaps and detergents. Deodorizer distillate is potentially utilized to produce biodiesel as raw material and is a source of highly valuable phytochemicals. As a result, the wastes of rapeseed oil that may be considered commercially insignificant are useful for extracting or isolating valuable industrial compounds with broad applications. This chapter reviewed the various byproducts resulting from the industrial extraction process of rapeseed oil and up-to-date data. In addition, the phytochemicals of rapeseed oil’s byproducts and the technologies applied for the revalorization of rapeseed oil byproducts have been discussed. Finally, the applications of rapeseed oil byproducts have been presented.
