A Quick Look Into Dairy Production
Dairy is often something I rely on—ice cream and froyo keep me cool in the summer, hot chocolate and lattes keep me warm in the winter, and a cold glass of milk can instantly transport me back to childhood. All thanks go straight to the dairy cows and farmers working around the clock. In fact, a single cow can produce approximately 6.5 gallons of milk daily and supply over 21,000 pounds of milk yearly, not counting the milk her newborn calf will drink. That milk is just the start for dairy lovers. It may be transformed into cheese, yogurt, or a number of other food products through a series of well-monitored, science-driven steps on the farm, in warehouses and in factories. From cow to carton Shortly after giving birth to a calf, a dairy cow will start producing milk, and she will continue to do so for about ten months. This milk is collected on the farm and then transported for further processing, specifically for pasteurization and homogenization. Pasteurization is the means of treating a food product, often by heat, to reduce the risk of foodborne pathogens surviving in the product that could potentially make consumers sick. The Food and Drug Administration (FDA) regulates this process very carefully for milk products, specifying the amount of time and temperature milk must be heated—for example, lower temperatures require longer time to make sure any harmful pathogens are destroyed. The next step, homogenization, ensures that the contents of milk—its protein, fat and sugars—remain one consistent mixture rather than clumps separated among liquid. The pasteurized, homogenized milk then may be packed into various containers, stored at safe temperatures, and shipped to grocery stores and markets for human consumption. Plant-based products like almond milk and oat milk will similarly go through an FDA-mandated process to […]
