Various groups around the world are focusing their attention on haskap berries. We are continuously looking to improve our knowledge base and commission our own research to find out how to deliver delicious and healthy products to our consumers.

As part of our commitment to evidence based research we host a symposium once a year at Dalhousie University in Halifax, Nova Scotia where researchers can present their latest findings. The main topics of research include agriculture, haskap pollination, chemical composition of the berries, how to retain the bioactive content of the berries in product development and haskap health benefits.

Dr Vasantha Rupasinghe and his team from the Department of Agriculture at Dalhousie University have published a very comprehensive overview of haskap research in the Journal of Functional Foods in May 2018: The potential health benefits of haskap (Lonicera caerulea L.): Role of cyanidin-3-O-glucoside


Come back often as we continue to add and sharing new and exciting research on everything haskap.
