The chemistry of contaminant detection

摘要

Machine learning especially is pushing the innovation boundaries in food manufacturing and streamlining production processes. It is a science which requires a deep understanding of the chemical makeup and molecular structures of foods.How fats, proteins, carbohydrates and sugars change during processing and storage will initiate a chemical reaction. To the naked eye, and even taste buds, these changes are barely noticeable. Yet, for wet and conductive foods, such as bread, meats, dairy products and ready meals, to a sensitive metal detector inspecting the same foods over an eight hour shift, they can appear like completely different products.Thermal changes and water content are the main factors that can interfere with metal detector signals. Dealing with higher amplitudes of product signal can be especially pronounced in some processing plants.
