Pectin isolated from lemon with two degrees of methylation (DM18 and DM88) was used to form microbeads with either alginate or chitosan, producing four bead types, which were alginate/pectin DM18 (AlgDM18), alginate/pectin DM88 (AlgDM88), chitosan/pectin DM18 (ChitoDM18), and chitosan/pectin DM88 (ChitoDM88).</div><div>The beads were loaded with <em>L. plantarum</em>, and it was demonstrated that all pectin-based beads could preserve the viability of <em>L. plantarum</em> after encapsulation. While some differences in metabolism was observed, the alginate-pectin beads exhibited higher activity and loading capacity. Then these beads were tested on intestinal epithelial cells to assess their protective impact in the presence of a barrier disruptor A23187. The effect on gut barrier function demonstrates that the composition of the microbeads significantly affected their protective effects.

Results revealed that all chitosans confer cryo-protection to gluten proteins, with the 30 kDa chitosan exhibiting the most pronounced effect. Chitosan mitigated the increase in free sulfhydryl, carbonyl, and hydrophobic group content, thus maintaining the structural integrity of gluten protein to some extent, and further resulting in increases of 42.48%, 36.68%, 20.34% and 13.63% in water-holding capacity, emulsifying activity, foaming activity and foam stability, respectively, as compared to original gluten protein. Furthermore, chitosan slowed down the water migration, thereby delaying ice recrystallization, and ultimately reducing the damage to gluten network.

By focusing on the mechanisms through which these polysaccharides influence metabolic processes, this paper explores how they contribute to anti-obesity effects, such as reducing inflammation, enhancing satiety, and improving lipid metabolism. The review synthesizes findings from both in vivo and in vitro studies to present a comprehensive overview of how macroalgal polysaccharides facilitate the growth of beneficial gut bacteria, which in turn produce metabolites like short-chain fatty acids (SCFAs). These metabolites play crucial roles in energy homeostasis, immune modulation, and overall host health. However, to fully understand how these elements contribute to maintaining gut balance and overall health, more research through animal studies and human clinical trials is needed.

The results showed that the SPI aggregates exhibited a trend of depolymerization followed by reaggregation with the increase of PEF intensity. At 10 and 15 kV/cm, the polarization effect of PEF induced the unfolding of the tertiary structure of SPI, leading to the enhancement of the electronegativity of the side chains, and the electrostatic repulsive force between the molecules promoted the depolymerization of SPI aggregates. However, with the withdrawal of PEF, the structure of the SPI was partially reversible, resulting in a limited depolymerization effect. When the PEF intensity reached 20 kV/cm and above, SPI underwentstructure unfolding, subunit dissociation, continuous exposure of hydrophobic groups and sulfhydryl groups, and ultimately reaggregation mediated by hydrophobic interactions and disulfide bonding, resulting in the formation of high molecular weight soluble and insoluble protein aggregates.
