Much of the juice sold in supermarkets is pasteurized, meaning it has been heat-treated to kill bacteria that cause food-borne illnesses. Some supermarket delis, cafes and restaurants, however, sell fresh-squeezed juice. Squeezing and blending juice on-site allows juice sellers to create tantalizing flavor combinations, but not everyone can consume freshly squeezed beverages, especially children, pregnant women, the elderly and anyone with a compromised immune system. Whether you buy unpasteurized juice or make it yourself, it must be stored properly to be consumed safely.
Place a thermometer in your refrigerator to check the temperature. The refrigerator's temperature must be 40 degrees Fahrenheit or colder to keep harmful bacteria at bay.
Wash a glass or plastic container to ensure that it's bacteria-free. Transfer the fresh-squeezed juice from your juicer, blender or to-go cup into the container, close it tight and place it in the fridge. Store unpasteurized juice for no longer than three days.
Fill a large bowl with ice and set your juice pitcher down in it if you plan to serve fresh-squeezed, unpasteurized juice at a family breakfast or luncheon. Let everyone know that the juice is unpasteurized, so that anyone who shouldn't consume it can avoid it.
