متن کاملGrape Juice Quality Control by Means of H NMR Spectroscopy and Chemometric Analysis
This study shows the potential of 1 H NMR and chemometrics for quality control of grape juices. A wide range of quality assurance parameters were accessible on a single 1 H NMR experiment obtained directly from the samples, such as high amounts of ethanol. The results demonstrated the importance of storing the grape juices under refrigeration after the bottles were opened, in order to minimize ...
