Nanocarriers based on polysaccharides for improving the stability and bioavailability of Anthocyanins: A review

Abstract

Anthocyanins have good health benefits, but their poor stability limits their use in the food industry. Increasing the stability of ACNs is necessary to facilitate their absorption, metabolism and to improve their health benefits. A number of methods have been developed for the targeted release of ACNs in terms of improving bioavailability, and the selection of suitable biopolymer-based edible wall materials is an important factor in achieving the desired goal. Polysaccharides are ideal nanocarrier materials for ACNs due to their wide availability, low price and biodegradability. This review describes the chemical structure of ACNs and their benefits to human health, followed by a systematic review of the factors affecting the stability of ACNs. The polysaccharides that are often used as carriers for ACNs and the methods used to prepare ACNs-polysaccharide nanocarriers are summarized and their effects on the stability and bioavailability of ACNs are described. This review summarized the research progress of polysaccharide nanoparticles in improving the stability and bioavailability of ACNs for encapsulated delivery, presented the challenges and prospects of polysaccharide nanoparticles as ACNs carriers for food applications based on current knowledge, and provided new insights into improving the stability and bioavailability of ACNs by encapsulation with edible polysaccharide nanocarriers.
