Abstract:
Pineapple (Ananas comosus) is a major tropical fruit whose industrial processing generates massive by-products, such as peels and cores. Recent research indicates that pineapple polysaccharides (PPs) are a key bioactive component within these waste streams. While existing literature often generalizes fruit polysaccharides, this article specifically addresses the unique structural characteristics of PPs that distinguish them from other pectic sources. These polysaccharides exhibit numerous health benefits, including antioxidant, antibacterial, anti-inflammatory, anticancer, and hypoglycemic activities. This investigation critically evaluates extraction-purification synergies, proposed chemical structures, and how these structures dictate their biological activities. By identifying current limitations in structural elucidation, this review fills the research gap between fundamental studies and industrial value-added applications, providing a scientific rationale for the future development of PPs in the functional food and pharmaceutical sectors.
