Qualification of Powdered Gelatin Agar by NIR Spectroscopy

Agar is a mixture of polysaccharides widely used in food, chemical and pharmaceutical industries for its jelly-like structure. As it is obtained from different species of red algae, its quality can vary from lot to lot. In this application note, ABB Analytical Measurements determines if NIR spectroscopy can be used to identify optimal and sub-optimal lots of powdered gelatin agar.
