Determination of polyunsaturated and omega-3 fatty acids in vegetable oils and animal fats by the double-quantum filtered correlation spectroscopy (DQF-COSY)
SSRN Electronic Journal（2022）
Abstract
•Quantification of molar concentrations of polyunsaturated and omega-3 fatty acids.•Use of characteristic correlated peaks of the DQF-COSY spectrum as quantitative peaks.•Validation with trueness, selectivity, precision, limit of quantification, and linearity.•Comparison with the GC method by quantifying 14 kinds of vegetable oils, 5 kinds of animal fats and 3 kinds of blend oils.
