Preparation and application of modified Aronia melanocarpa pectin-whey protein stabilized clove essential oil pickering emulsion sustained-release preservative pads

open access: yesFood Chemistry: X
Aronia melanocarpa Pectin (AP) was modified via alkaline/enzymatic/high-pressure enzymatic methods. High-pressure enzymatic pectin (HPP-AP) exhibited the lowest esterification degree with galacturonic acid content, optimal shear-thinning behavior, and ...

Thermal degradation of citrus pectin in low-moisture environment - Influence of acidic and alkaline pre-treatment [PDF]

open access: yes, 2018
Pectin powder is degraded during storage and transport by demethoxylation and depolymerisation. The degradation mechanisms and especially the influence of pre-treatments on the degradation reactions are not completely understood.
