The binding ratios, physicochemical and structural characteristics of these pectin-anthocyanin complexes, and their binding mechanisms were analyzed. The HG fraction exhibited the highest binding ratio with C3G. Zeta potential and particle size analyses indicated that the HG fraction had a significantly higher negative charge compared to RG-І at pH 3.7, and the complexes exhibited an increase in particle size relative to the individual pectin fractions. Furthermore, data from <sup>1</sup>H NMR and isothermal titration calorimetry (ITC) confirmed that hydrogen bonding, electrostatic interactions, and hydrophobic interactions primarily facilitated the binding interactions. In the binding interactions involving HG/RG-І and C3G/P3G, the Δδ<sub>max</sub>, binding constant, and Gibbs free energy (ΔG) of the HG fraction were greater than those of the RG-І fraction, while C3G exhibited stronger binding characteristics than P3G. However, the RG-І fraction demonstrated stronger binding to P3M than to HG. The interactions between pectin and anthocyanins are highly dependent on the structural characteristics of both components.

This study investigated the protective mechanism of Pac using a high-fat diet-induced non-alcoholic fatty liver disease (NAFLD) mouse model. 16S rRNA sequencing of gut microbiota revealed that Pac administration reduced the <em>Firmicutes</em> to <em>Bacteroidetes</em> ratio, restored <em>Akkermansia</em> abundance, decreased <em>Desulfovibrio</em> and <em>Streptococcus</em> population, and ameliorated gut dysbiosis. Concurrently, Pac treatment reduced the expression of hepatic inflammatory factors by mainly adjusted LPS/TLR4/MYD88/NFκB pathway.

Specifically, Pac inhibited FASN, SREBP1c, and SCD1 expression while upregulating PPARα and CPT1α, thereby improving high-fat diet-induced hepatic steatosis in mice. Additionally, Pac treatment reduced hepatocellular apoptosis. Non-targeted liver metabolomics analysis following Pac intervention revealed increased levels of acylcarnitine and oleic acid.

High-quality starch hydrolysate products serve numerous applications, including ingredients in food, textiles, paper, cosmetics, bioplastics, pharmaceuticals and construction. However, impurities such as colour molecules, characteristic flavours, salts, and proteins encountered in the solution along the starch processing steps can compromise product quality. With increasing emphasis on organic and sustainable production, starch hydrolysates must meet higher health and environmental standards. This review provides a comprehensive overview of starch hydrolysates production and purification. It explores the chemical processes leading to the formation of impurities and their impact on the final product composition and specific characteristics. Downstream processing methods for recovery, purification, and concentration are also investigated, comparing traditional techniques with emerging membrane-based technologies. Membrane technologies offer a potential solution for purifying plant-based starch hydrolysates efficiently and sustainably by enhancing purification while reducing energy consumption and waste generation. They operate at lower temperatures, avoiding phase transitions, extra heating, chemicals, and solvent exchanges. Although membrane technologies are widely used in various food industries, minimal research exist on their applications in starch hydrolysate processing, with limited experimental validation available.
