Anthocyanin Degradation Of Blueberry-Aronia Nectar In Glass Compared With Carton During Storage

Blueberry-aronia nectar was prepared using concentrates of blueberry (Vaccinium angustifolium) and aronia (Aronia melanocarpa), and mixed with water, citric acid, and sugar. The nectars were then packaged in carton or glass containers and stored for 183 days. A significantly higher degradation rate (22%) was observed in the carton-packaged nectar than in glass, said the researchers. This study shows a comparison between nectar packaged in glass and in carton, which is a key study for shelf life evaluation in the fruit packaging industry and for consumer awareness of the impact of different packaging on food quality, they added.
