Abstract

The “Hydroxycinnamic Acids” chapter focuses on the occurrence, separation, properties, food, and other applications of the main antioxidant compounds from this chemical class. An up-to-date review on the cinnamic acid as the reference compound, as well as on p-coumaric, caffeic, ferulic, sinapic, chlorogenic, and rosmarinic acids was presented. The recent identified hydroxycinnamic acid derivatives were also highlighted. A comprehensive biosynthetic approach for the above-mentioned hydroxycinnamic acids was discussed. An important part of this chapter was dedicated to the food applications of these antioxidants and the corresponding extracts as well as their interactions with other ingredients from food matrices. Cinnamic acid has no antioxidant activity, but it was investigated, together with cinnamaldehyde, as antimicrobial and preservative in food nanoemulsions and products. Many food applications were found for simple hydroxycinnamic acids and their derivatives. p-Coumaric, caffeic, ferulic, and sinapic acids were discussed in relation with their interactions with food biomacromolecules (proteins and oligo- and polysaccharides), antioxidant properties against degradation of some vegetable and food constituents such as anthocyanins, and even covalent binding to food biopolymers for novel ingredients and functional foods. Biotechnological aspects related to enhancing the hydroxycinnamic acid production and optimized extraction techniques were also investigated. These aspects were considered for hydroxycinnamic acid esters, such as mono- and di-p-coumaroyl/caffeoyl/feruloyl/sinapoylquinic acids, and the corresponding mixed esters, known as chlorogenic acids, rosmarinic, chicoric, or aldaric acids. Chlorogenic and rosmarinic acids are valuable natural antioxidants with many food applications even through the natural sources such as green coffee beans and rosemary, or concentrated formulations. Generally, chlorogenic and rosmarinic acids-based extracts, obtained by optimized production and extraction from various sources, are used. Finally, a comprehensive conclusion and future perspectives point out the main directions on hydroxycinnamic acids research and applications are presented.
