Consumer acceptance of meat depends on its colour and there is a negative bias in North America for broiler dark meat. Freezing and cooking leads to changes in meat characteristics and colour of broiler chicken thighs. The first experiment focused on the effect of freezing and cooking on broiler...

Tan spot, caused by Pyrenophora tritici-repentis, is an important foliar disease of wheat. Three genes (stp, unp and glu) encoding proteins previously found to be more abundant in pathogenic versus non-pathogenic fungal isolates were cloned, characterized, heterologously expressed, and silenced...

Consumers and Canadian poultry processors were interviewed to understand the overall perception of bone-in chicken meat and to gain insight on the defect of black bone discoloration, a color defect that appears in cooked bone-in chicken. Through the consumer science technique of laddering, food...

Clubroot, caused by Plasmodiophora brassicae Woronin, is a major soilborne disease of canola in Alberta. Root exudates from host (Chinese cabbage (Brassica rapa var. pekinensis, cv. Granaat), canola (Brassica rapa L.)) and non-host (perennial ryegrass (Lolium perenne L.)) plants were found to...

Studies focused on developing a semiochemical-based monitoring system for Plutella xylostella (L.) using sex pheromone and Z3-hexenyl acetate. A commercially available pheromone trapping system was used to capture male moths at sites in Alberta in 2007 and 2008. Larval sampling occurred every...
