“…To date, the majority of research has been carried out on pectin, likely because it is the CPS with the most structural variations. Extensive research has identified multiple characteristics that affect the interaction capacity of different CPSs, including: - ‐botanical origin of cell wall and pomace (cellulose, hemicelluloses, and pectins) (Brahem et al., 2019; Costa, Rogez, & Pena, 2015; Le Bourvellec et al., 2005, 2012; Y. Liu et al., 2019; Padayachee et al., 2012a; Phan et al., 2015, 2017; Ruiz‐Garcia, Smith, & Bindon, 2014; M. Shi et al., 2019; L. Y. Wu et al., 2016; L. Y. Wu, Sanguansri, & Augustin, 2015; L. Y. Wu, Melton, Sanguansri, & Augustin, 2014; L. Y. Wu, Sanguansri, & Augustin, 2014);
- ‐surface area/porosity (Bermúdez‐Oria, Rodríguez‐Gutiérrez, Fernández‐Prior, Vioque, & Fernández‐Bolaños, 2019; Le Bourvellec & Renard, 2005; Le Bourvellec et al., 2005, 2012; D. Liu et al., 2017; D. Liu, Lopez‐Sanchez, Martinez‐Sanz, Gilbert, & Gidley, 2019);
- ‐molecular weight (Guo et al., 2018; He et al., 2019; Larsen, Buerschaper, Schieber, & Weber, 2019; J. Zhu, Zhang, Tang, & Zhao, 2018);
- ‐degree of esterification of pectins (Buchweitz, Speth, Kammerer, & Carle, 2013b; A. Fernandes et al., 2020; Larsen et al., 2019; Mamet et al., 2018; Padayachee et al., 2012b; Watrelot et al., 2013);
- ‐side chains and branching ratios (Brahem et al., 2019; Koh, Xu, & Wicker, 2020; Watrelot et al., 2014);
- ‐other molecules in the cell walls (P. A. R. Fernandes et al., 2020; Le Bourvellec et al., 2012; D. Liu et al., 2017; Ye et al., 2009).
