Abstract

γ-linolenic is one kind of polyunsaturated fatty acid (PUFA) essential for human body. The aim of this study was to investigate the feasibility of Near Infrared Spectroscopy (NIRS) to determine the content of γ-linolenic in donkey meat. The spectra of forty donkey meat samples on the spectral range of 4000-12500 cm-1 were used to develop calibration models with the algorithms of forward iPLS (FiPLS) and backward iPLS (BiPLS). The best calibration is obtained using FiPLS with 80 intervals of the minced sample spectra, the determination coefficient, standard error, and the ratio of performance deviation of cross-validation of which is 0.604, 157.3 mg/100g, and 1.60. The result shows that NIRS combined with chemometrics can predict γ-linolenic in donkey meat. Further studies are needed to improve the prediction performance of calibration models.
