absorbed. In the treatment of diabetes there are some established alpha- glucosidase inhibitors such as Acarbose, but efforts have been made to search for active and safe natural inhibitors. “We have found a really exciting source of a potential natural alpha- glucosidase inhibitor in these lingonberries,” explains Ross. “They show remarkable levels of alpha- glucosidase inhibition ... comparable to the pharmaceutical available. This is quite an exciting result.”


Just like blueberries, lingonberries need pollinizer cultivars to produce good-sized berries. These are needed for both spring and summer bloom periods. Bees, flies, bumblebees, butterflies and other flying insects are all important pollinators. Fields need to be kept open and in full sun for optimal fruit set. Various organic mulches can be used to grow lingonberries, including sawdust, compost, chipped yard debris, wood chips and manure. About 10 tons of organic material per acre need to be incorporated into the soil as an amendment before planting. Overhead sprinklers can be used in lingonberry production, but drip irrigation is the preferred method.


Berries are harvested when they are light red to dark red. If berries are harvested too early they taste bitter, although they ripen to a dark red color after being stored for several weeks under refrigeration.


Research is underway to use soluble solids as a way to determine the best time to harvest lingonberries. They can be eaten fresh but are more commonly processed into sweet food products such as jams, jellies, syrups, and beverage concentrates. They are also used to make liqueurs, wine, fruit leather, and dried fruit. Lingonberries are usually mixed with other berries, especially cranberries.


Ross says it is exciting to conduct research on crops in other countries with a view to identifying and developing Canadian versions as new super fruits to compete with the Pomegranate and Kiwi fruit. “We need to define the health promoting properties and benefits of our (Canadian) super fruits. It will be very beneficial to the berry growing economy.”
