Soybean soluble polysaccharide (SSPS) is a macromolecule extracted from cell wall material of cotyledons of soybeans [98]. Its structure is similar to pectin, being considered as an acidic carbohydrate composed mainly of rhamnogalacturonan backbone branched by β-1,4-galactan, homogalacturonan, and α-1,3- or α-1,5-arabinan chains [112]. Beyond its ability to form films with excellent mechanical properties and high thermal stability, SSPS films and coatings are extremely sensitive to water molecules (Table 2.5) [113, 114].
