ABSTRACT
Tomato (Lycopersicon esculentum) is a widely cultivated vegetable crop and it is mainly processed to tomato paste, juice, ketchup, purée, and canned tomatoes. However, tomato processing at the industrial scale leads to large quantities of wastes, such as pulp, seeds, peels, and fibrous part residues. The tomato waste management is therefore a worldwide problem in terms of environmental and economic aspects. It is generally agreed that reuse or recycle of these byproducts could decrease processing costs and the corresponding wastes could be considered rich sources of nutrients and bioactive compounds.
This chapter will therefore focus on the various bioactive compounds extracted from tomato wastes, such as carotenoids, proteins, peptides, oil, and dietary fibers. The extraction methods for the release and extraction of these bioactive compounds are also highlighted in this book chapter.
