This paper reports on the results obtained with the pulsed nuclear magnetic resonance (P-NMR) technique applied for determining fat content in fresh meat. The interfering moisture content of meat was removed by microwave drying and the dried residue was quantitatively transferred into the P-NMR tubes. The total analysis time was about 50 min. Experiments were performed with rendered pure pork, beef and goose fats, sunflower oil and with lean pork - fat and lean beef - tallow mixtures (batters). The regression (prediction) equations (intensity of P-NMR signal vs. fat content determined with the Soxhlet reference method) of the sunflower oil and fat samples did not differ appreciably. Consequently, contrary to the results obtained with the CW-NMR technique, the variability of the fatty acid composition of the examined fats and oil had no substantial effect on the regression (prediction) equations in this case. On the other hand, there was a considerable difference between the regression lines of the lean pork-fat and lean beef-tallow mixtures. Therefore, due to the interfering effect of the non-fat dry matter and the type of meat on the intensity of P-NMR signal, this technique can only have a restricted practical application in the in-line process control of fat content of meats.
Abstract
A comprehensive investigation has been made of a set of 14th to 16th-century parchment bookbindings from the Historical Archives of the City of Turin. Advanced physico-chemical techniques, such as thermal analysis (DSC, TG and DTA), spectroscopy (FTIR and UV-Vis-NIR), scanning electron microscopy (SEM) and unilateral nuclear magnetic resonance (NMR-ProFiler) were employed to assess specific deterioration processes occurring at different levels in the hierarchical structure of parchment. Changes in the measured physical and chemical parameter values of parchment due to interaction with the environment were used to identify possible deterioration pathways.
see what type of interactions take place between PPB and DPPE vesicles, studies were carried out with PPB doped DPPE dispersions using DSC and ( 1 H and 31 P) NMR. Materials and methods Sample preparation
characterization was done by X-ray diffractometry (XRD), infrared (IR) spectroscopy, thermogravimetry (TG) and nuclear magnetic resonance ( 29 Si NMR). The chemical stability was implemented for pH varying at 1.0–6.0. Methods and materials
