Food Coloring is technically any dye, pigment or substance that can impart color when added or applied to a food, drug, cosmetic or to the human body. While most people associate it with actual edible items, there are far more settings that benefit from the vivid properties. Non-food use occurs with regularity in research, medical and educational settings. The commercial non-food use of food color is widespread across many different industries and used by thousands of companies. Food coloring used within a company is usually part of the manufacturing process or a direct end use incorporated into a good or service. Food coloring is often used in the production of goods as a means to visually identify that automation methods are functioning properly. This use is often found on production lines containing various viscous or liquid material that would not be easily identified without an added hue. Bar tending schools use several different colors during the hands on training to mimic the range of colors found in liquor and mixers. In educational settings, food coloring is often used in both preschools and Universities, albeit for very different reasons. Most preschools incorporate food coloring into creative expression and color mixing lessons. At Universities and Colleges food coloring is widely used in chemistry, biology and various research settings whereby the inclusion of color enhances the learning process.
