Once radiopharmaceuticals enter the body and travel to an organ, they begin to interact with the processes of that organ. The radioactivity is picked up by cameras or computers and used to map the process. For example, an ultrasound can show an image of an organ and reveal if a tumor or other abnormality is present. Nuclear medicine can show how the process of glucose metabolism is functioning in the organ.
250g bags of our biltong can last up to 4-months, and we have food testing certificates to prove this, however, we do not advise that you keep it that long. The larger the bag of biltong, i.e 500g or 1kg, the more moisture is contained within the sealed bag.
Shelf Life of Coffee. The shelf life of coffee will depend upon whether it is whole bean or ground as well as if the vacuum seal has been removed. Whole bean coffee can be stored in an airtight container (after removing the vacuum seal) in the pantry for about three weeks, and in the freezer for about three months. Coffee which has been ground only has a shelf life in the pantry of about 7-10 days, but can survive in the refrigerator for about three weeks. Freezing ground coffee is not recommended. Unopened coffee, whether ground or whole bean, will last in the pantry for about two years.
