There is a need to ensure extraction yield of the soluble coffee process, thus we need a method to analyze carbohydrate degradation products produced after hydrolisys of polysaccharides due to high temperatures used during extraction. It is important to measure in process the extraction efficiency to fine tune the process. Which secondary rapid method could be used to measure carbohydrate degradation products in the liquid phase and how can it be calibrated on primary methods?
Dear Giulia,
Near infrared (NIR) and Raman spectroscopies have already demonstrated their potential for in-situ analysis. It is nevertheless difficult to say in advance which one would be the best for this specific application. it must therefore be tested.
Best regards,
Ludovic.
Hyper spectral imaging and NIR as mentioned above. but you can try electronic nose (volatiles), although you have to do a lot of background research.
