We propose a J-selective quantitative distortionless enhancement by polarization transfer (J-selective QDEPT) 13C NMR method with enhanced sensitivity for accurate determination of the fatty acid compositions of edible oils. The J-selective QDEPT protocol is developed by targeted optimization of the known Q-DEPT+ experiment. Based on the one-bond C-H J-coupling constants (1JCH) which can be measured...
Total volatile basic nitrogen (TVB-N) content is used to evaluate Pacific oyster (Crassostrea gigas) freshness. In this work, hyperspectral imaging (HSI; 400–1000 nm) was used to measure the TVB-N content in Pacific oysters. Accordingly, Pacific oyster samples stored in 15 °C water were assessed at intervals after 1, 3, 5, 7, or 9 days. Minimum noise separation processing of the hyperspectral images...
