Innovative Applications of Pectin in Lipid Management: Mechanisms, Modifications, Synergies, Nanocarrier Systems, and Safety Considerations.

ABSTRACT

Pectin, a natural polysaccharide predominantly sourced from the cell walls of terrestrial plants, is widely regarded for its gelling, thickening, and stabilizing properties, which have extensive applications in the food, pharmaceutical, and biotechnological industries. This review discusses the mechanistic pathways by which pectin mediates its lipid-lowering properties, such as pectin's antioxidant activity, the modulation of gut microbiota, its anti-inflammatory properties, its capacity to bind bile acids and cholesterol, and its impact on the expression of genes associated with lipid metabolism. To enhance its hypolipidemic properties, chemical, physical, and enzymatic modification techniques are explored. Additionally, the synergistic effects of pectin in combination with other bioactive compounds such as phytosterols and polyphenols, as well as its potential in nanocarrier-mediated delivery systems for lipid-lowering agents, are highlighted. The review also conducts a critical analysis of the safety and regulatory considerations associated with pectin use, emphasizing the necessity for comprehensive toxicological evaluations and adherence to regulatory standards. This paper underscores the growing potential of pectin not only as a dietary fiber but also as a multifaceted agent for ameliorating hyperlipidemia, catalyzing a shift toward more targeted and efficacious lipid-lowering strategies.
