Honey as a food product with plant origin that nearly ninety percent of its dry weight is composed of sugars (mostly fructose and glucose) which has many food and pharmaceutical properties. So honey quality strongly depends on bees feeding practices. For this reason common indexes is defined generally are on the basis of hony composition, for example fructose and reducing sugar portion must be at least thirty and sixty-five percent respectively of total weight or sucrose percent must be utmost five and otherwise puts into question honey quality. To check the quality of five honey samples taken from the market, indexes such as water content, sugar composition(fructose, reducing and total... 

Our lives are redefined by the constant emergence of new products that are easier, smarter and faster to use than their predecessors. Enabling this evolution are advances in miniaturization that have produced smaller mechanical, optical, and electronic products and devices. In the field of analytical chemistry, portable and handheld devices are now commercially available for a wide range of spectroscopic techniques. One of the most important applications of portable spectroscopic devices is in determining the authenticity of food. Nowadays, the development of a low-cost, fast and non-destructive method that can be implemented in the entire food supply chain has become a research field of...
