Description

Introduction: Low-caliber vegetables are used to produce juices, flours and dried snacks. The valorization of non-marketable products through the development of new high value-added food products is aligned with current trends and contributes for a more sustainable and circular food sector. PEF is an emerging and promising technology with the potential to reduce freeze-drying time and improve the quality characteristics of processed fruit and vegetables. Objectives: This study evaluated the impact of PEF pretreatment on the physicochemical and bioactive properties of a freeze-dried snack made from low-caliber beetroot.
