Pimenta dioica: a review on its composition, phytochemistry, and applications in food technology

Abstract

Recently, the utilisation of essential oils extracted from spices has been garnering interest due to their phytochemical constituents which could be extracted using various techniques. Studies have demonstrated antimicrobial activities from essential oils against foodborne pathogens, and thus, their application has been considered to be a possible preservative for foods. Pimenta dioica is a type of aromatic plant, and its essential oil is is rich in eugenol, a phenolic compound with wide antimicrobial spectrum. Other bioactive compounds in P. dioica extract include glycosides, alkaloids, carbohydrates, proteins, flavonoids, and tannins. The incorporation of essential oils into food is limited because they have an intense aroma, and might affect consumer acceptance. Therefore, nanotechnology is applied as a tool to rectify this limitation, and it is now possible to apply essential oils in active packaging, or to encapsulate them in biodegradable materials or edible coatings with controlled release. However, there is little information on the interaction of nanoencapsulated bioactive composites, and thus, it is essential to assess the viability of biomaterials before their use. The objective of this work is to show the use of the essential oil of Pimenta dioica and its phytochemical composites in a general way for its potential application in food technology.
