- Abstract
In this study, lipid content of live Eriocheir sinensis has been quickly and accurately determined by low‐field 1H Nuclear magnetic resonance (LF‐1H NMR). The experimental parameters of LF‐1H NMR have been optimized and the validity of the established standard method has been confirmed with traditional Soxhlet extraction method. Results show that the lipid signal intensity is strongly correlated with its content and exhibits a good linear correlation (Y = 0.0376 + 4.899X, R2 = 0.9999), thus demonstrating favorable accuracy and sensitivity for the quantitative determination of lipid content. In conclusion, the lipid content of live E. Sinensis can be directly obtained based on an established method, indicating a great application potential in food and other fields. The lipid content of live E. sinensis was quickly and accurately determined with low‐field 1H nuclear magnetic resonance (LF‐1H NMR). The experimental parameters of LF‐1H NMR were optimized, and the validity of the established standard method has been confirmed with the traditional Soxhlet extraction method. The lipid content of live E. sinensis can be directly determined based on an established method, indicating great application potential in food and other fields.
