container: low density polyethylene (PE-LD) bags and oriented polystyrene (OPS) boxes on selected quality parameters in frozen broccoli. The experimental material was the broccoli cultivar LordF1. The vegetable was subjected to blanching, freezing and 3-month storage. At the every stage of an experiment the material was examined in terms of: vitamin C content; β-carotene; total polyphenols; and antioxidant potential, which was determined basing on the ability to quench the ABTS˙+ free radical. It has been found that vegetables which were kept frozen for 3 months in two types of container had parallel levels of vitamin C, β-carotene; total polyphenols; and similar antioxidative potential.
