Stabilization of refrigerated avocado pulp: Effect of Allium and Brassica extracts on enzymatic browning

The aim of this paper was to study the effectiveness of Allium and Brassica extracts to inhibit the evolution of enzymatic browning of avocado pulp tissue stored at refrigeration temperature (4°C). Color parameters and mathematical modeling were employed to determine browning kinetics. In general, t...
