High pressure processing (HPP) of aronia berry puree: Pilot scale processing and a shelf-life study

The growing demand for minimal processed and antioxidant-rich aronia berry products has stimulated the interest of food industry. Industrial sector demands methods to extend the microbial shelf-life and maintain its quality and nutritional values of aronia berry products during refrigerated storage. The results of this study demonstrated that HPP is effective in extending the microbial shelf-life, maintaining the quality and preserving the bioactive antioxidants of aronia berry puree during 8 weeks of refrigerated storage.
