ABSTRACT
Coriander is an important commercial spice with a broad spectrum of industrial applications. It is extensively marketed for its petroselinic acid-rich oil, oleoresin, and linalool-rich essential oil, widely used in food, cosmetics, and chemical industries. However, the extraction process results in vast amounts of solid residues (waste and by-products) that could be associated with severe environmental concerns. Strategies focused on recycling waste/by-products and turning them into bio-resources have been successfully implemented to overcome these problems. Beyond reducing the environmental risk caused by the uncontrolled disposal of waste/by-products, their use as a consolidated source for the recovery of high added-value ingredients (essential minerals, dietary fibers, lignocellulosic materials, oleoresins, essential oils, and natural antioxidants) can open new avenues for the sustainable valorization and recycling of these underutilized resources, improving thus the environmental safety and circular economy. In this framework, this chapter provides a comprehensive overview of the state-of-the-art chemistry, nutritional, and health benefits and the current and prospective applications of coriander straw, press cake, and hydrodistilled by-products.
