Application Note: Food analysis with Confocal Raman Microscopy

In the food industry, various ingredients, additives and bio-polymers such as emulsifiers, stabilisers, carbohydrates or thickeners are commonly used in order to optimise the texture or the flavor of food. In this application note, WITec explore the use of confocal raman microscopy as a tool for food analysis.

Confocal Raman microscopy is a powerful tool for analysing of the chemical composition of heterogeneous samples on the sub-micrometer scale. In this application note it is demonstrated that the distribution of various chemical compounds in a banana, instant gravy thickener, emulsions, a candy and chocolate products could be successfully visualised, leading to a more comprehensive understanding of the product and the production process.
