Can you tell a bad olive oil from a good one? Like any food, there’s a certain pungency to the aroma of “off” olive oil and that of course affects the way it tastes and its nutritional benefits. Claudia Guillaume has extensive experience in sensory evaluation of olive oil and olive products. Originally from Argentina, Claudia Guillaume came to Australia in 2006 to head up Modern Olives Laboratory. Major players in the olive industry turn to the team at Modern Olives for help in project development, technical advice, applied research and of course olive- and olive-oil testing.
