Procedures to evaluate potential of plants as natural food preservatives: Phytochemical characterization, novel extraction technology, and safety evaluation—A comprehensive review

Abstract

There is increasing demand for natural food preservative in food manufacturing industry as it is the key to meet consumers' preferences toward healthier food choice. Plant is listed among the most important resources of bioactive components to be utilized as the green and natural food preservatives. There are more than 10,000 kinds of bioactive components in plants that possess antioxidant and antimicrobial properties. Artemisia with potential antimicrobial and antioxidant attributes, as well as functional and medicinal properties, is one of the most important plant species. The manuscript presents a comprehensive review of the potential of the Artemisia species as natural food preservatives. The current challenges and ways forward in using Artemisia EOs and extracts as food preservatives are also discussed. This topic is timely and important considering the natural preservatives used to replace chemical ingredients, sustaining quality, healthy properties, and shelf life of food products as well as efficient and novel extraction techniques.
