Title

Effect of packaging material and storage conditions on „Bobo-Frut” juice quality

Abstract

The effect of packaging material (colourless and brown glass), intensity of natural light and different storage temperature (room and refrigeration) on the quality of some „Bobo-Frut” juice for children was tested in this paper. Experiment was carried out during 6 months storage. The loss in contents of vitamin C and carotenoids as well as changes in colour and sensory quality were analysed. Results showed significant changes in L-ascorbic acid content and anthocyanin degradation index as a result of storage while any significant storage influence was observed on carotenoids content and sensory quality. The most important factors responsible for quality losses were in sequence: storage temperature, colour of packaging material and intensity of light. The samples, which were kept at refrigeration temperature in the dark were the most stable.
