High-resolution magic angle spinning (HRMAS) NMR is probably the most apt NMR method to analyze complex materials involving a solid phase, e.g. foodstuffs. We present here an HRMAS analysis of grated cheese (Parmigiano Reggiano). A full NMR characterization of this cheese allows the identification of the presence of fatty acids (saturated and unsaturated), amino acids and other small organic molecules. Since the presence and relative concentration of these molecules have previously been shown to correlate with organoleptic, origin and age characterization, HRMAS NMR of cheese is likely to provide a good complimentary tool for the analysis of this food material.
高分辨率魔角旋转（HRMAS）核磁共振可能是分析涉及固相的复杂材料（如食品）最合适的核磁共振方法。我们在此展示对磨碎的帕尔马干酪（Parmigiano Reggiano）的HRMAS分析。对这种奶酪进行全面的核磁共振表征可以识别脂肪酸（饱和和不饱和）、氨基酸及其他小有机分子的存在。由于这些分子的存在和相对浓度此前已被证明与感官特性、产地和年份特征相关，奶酪的HRMAS核磁共振很可能为这种食品材料的分析提供一个很好的补充工具。
