Before refrigeration, food was preserved using salt, smoking, or ice harvested from frozen lakes. The invention of the electric refrigerator changed how people stored and preserved their food. In some countries, this new technology became more commonly available in homes during the 1920s and 1930s. People in those places were now able to keep food cold and fresh for extended periods. As a result, they were able to shop for certain foods and drinks less frequently.
