Half listening to the radio as I prepared my dinner, I was suddenly struck by the words of the reporter and turned up the volume. The radio program was talking about a demonstration that had taken place earlier that day in front of a large milk-processing plant in Montreal. Some 50 milk producers had gathered there to denounce the use of diafiltered milk from the United States in the industrial production of dairy products. Diafiltered milk is a product that has been filtered several times in order to obtain a very high protein liquid. It is also available in powder form. Canadian customs authorities consider diafiltered milk an ingredient, making the product exempt from tariffs on milk. Major dairy processors are delighted with this situation, as diafiltered milk allows them to save money. Not only is this milk competitively priced, but given its high protein content, it is also more efficient than Quebec milk for the industrial production of yoghurt and cheese. My thoughts were immediately drawn to the concept of a more “efficient” milk.
