S. gov), foods are classified into five major classes: fruits, vegetables, grains, protein foods, and dairy. ). In transparent foods, 19 20 Light Scattering Technology for Food Property, Quality and Safety Assessment light passes through the material straightly without changing the direction or being scattered.
A further description of photoluminescence processes is given in Chapter 2. 3 LIGHT SCATTERING AND ITS APPLICATIONS IN FOOD AND AGRICULTURE After the introduction of the basic concepts of light and optical theories, it is now appropriate to give a brief overview of light scattering technology and its applications for food property, quality, and safety assessment. Nature is full of light scattering phenomena. For instance, during a clear, sunny day, the sky looks particularly blue, because the scattering of blue light by fine particles in the atmosphere is predominant.
Quantum theory, also known as quantum mechanism or quantum physics, is able to deal with virtually all physical phenomena; it extends beyond the classical electromagnetic theory by explaining the interaction of light with matter at the atom and subatom levels. It provides a complete mathematical framework for describing light behavior and its interaction and exchange of energy with matter. In quantum theory, light exhibits both wave-like and particle-like behavior. When traveling in space or a medium, light behaves like electromagnetic waves, consisting of electric and magnetic fields.
