Research

Join us on a journey of exploration about this exciting berry!

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. And we take science very seriously.

As part of our commitment to evidence-based research we host a symposium twice a year in Nova Scotia where local researchers can present their latest findings. The main research areas are looking at the chemical composition of the berries, product development with retention of bioactive compounds, and haskap health benefits.

Our latest research project will be looking at which wild bees and other insects are involved in haskap pollination, and how best to preserve their natural habitat and forage in our orchards.

We will keep sharing new and exciting research on everything haskap on this page.
