Abstract
Polysaccharides with different zeta potential values, including guar gum (GG), gum Arabic (GA), and xanthan gum (XG), were combined with maltodextrin (MD) and then used as wall materials to encapsulate anthocyanins from aronia. Based on absolute zeta potential of 10 mV, wall materials were divided into two groups: MD (- 2.80 mV) and GG (- 3.49 mV) as non-ionic materials and GA (- 30.83 mV) and XG (- 65.87 mV) as anionic materials. The addition of aronia concentrates (pH 3.8) had no effect on zeta potential values in non-ionic MD and MD + GG, whereas it elevated zeta potential values in anionic MD + GA and MD + XG. Non-ionic MD and MD + GG exhibited higher encapsulation efficiency and storage stability of anthocyanins than anionic MD + GA and MD + XG. Principal component analysis showed that zeta potential values of wall materials positively correlated with encapsulation efficiency and storage stability of anthocyanins. The results indicate that non-ionic wall materials are suitable for anthocyanins encapsulation.
