A novel, sensitive and non‐destructive method for quantitative determination of lipid in live Eriocheir sinensis using low‐field ¹H Nuclear magnetic resonance

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, R 2 = 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.

Drivers of Consumer Preference Derived from Active Volatiles for Cooked Eriocheir sinensis

“…The Chinese mitten crab (Eriocheir sinensis) is an economically important aquatic product in Asian countries owing to its intense flavor and high nutritional value [3]. In China, crab culture yielded 808,274 tons of crab in 2021 (China Fishery Statistical Yearbook, 2022).…”
