Effects of ohmic and conventional heating on anthocyanin degradation during theprocessing of blueberry pulp
The present work evaluates the anthocyanin degradation in blueberry pulp after thermal treatment using ohmic and conventional heating. The ohmic heating technology was studied using a rotatable central composite design, and the variables studied were voltage and solids content. The anthocyanin content of the samples was determined using HPLC. The results show that degradation increased with bot...
متن کاملOxygen availability in model solutions and pur ees during heat treatment and the impact on vitamin C degradation
Oxygen availability in different media during heat treatment (8 h at 80 C) and the related vitamin C loss was assessed. Dissolved oxygen in water containing 3 mmol kg 1 of ascorbic acid decreased initially and seemed to be replaced by oxygen from the headspace in the course of time, as oxygen values increased again. In apple pur ee and carrot pur ee in contrast, oxygen was depleted within 60 mi...
