The Red OsierDogwood extract has been obtained, however, the extraction method has not been optimized to ensure thatmaximum yield of phenolics in the extract is achieved. Moreover shelf-life properties have not been evaluatedfor the resultant powdered extracts. Red Dog Enterprises Ltd. will need this information in order to completethe registration of the product with Canadian Food Inspection Agency (CFIA) Feed Section before it can bemarketed worldwide. Optimization of phenolic levels and completion of shelf life studies by the University ofManitoba will enable registration of the product. It is anticipated that registration of the product will openopportunities for Red Dog Enterprises Ltd. to create jobs in production, harvesting and marketing of Red OsierDogwood extracts.
