Fruit processing generates large amounts of waste such as peels, seeds, stones, and oilseed meals, whose disposal is problematic and legally restricted. The review aims to evaluate the potential of apple, grape, and citrus by‑products as sources of valuable compounds for food additives or supplements. The authors discuss the relevance of these by‑products through a review of literature on their composition and bioactive properties.
The processing of fruits results in high amounts of waste materials such as peels, seeds, stones, and oilseed meals. A disposal of these materials usually represents a problem that is further aggravated by legal restrictions. Thus new aspects concerning the use of these wastes as by-products for further exploitation on the production of food additives or supplements with high nutritional value have gained increasing interest because these are high-value products and their recovery may be economically attractive. It is well known that by-products represent an important source of sugars, minerals, organic acid, dietary fibre and phenolics which have a wide range of action which includes antitumoral, antiviral, antibacterial, cardioprotective and antimutagenic activities. This review discusses the potential of the most important by-products of apple, grape and citrus fruits processing as a source of valuable compounds. The relevance of this topic is illustrated by a number of references.
