Abstract
A method for the rapid analysis of the fatty acid components present in a fat and/or oil-containing material is provided wherein the levels and types of fatty acids present in a sample are determined using Fourier Transform Near Infrared (FT-NIR) spectroscopy. The FT-NIR technique is developed by preparing a calibration matrix based on FT-NIR and Gas Chromatography (GC) analysis of known standards, and subsequently using the calibration matrix to analyze the FT-NIR spectral data obtained from a sample to be tested.

A method for the determination of the fatty acid type and content of a fat or oil component of a material comprising:
- analyzing the fatty acid type and quantity of a baseline composition using a fatty acid reference analytical technique;
- analyzing the fatty acid type and quantity of said baseline composition using a Fourier Transform-Near Infrared (FT-NIR) analysis technique;
- preparing a calibration matrix by comparing results from said fatty acid reference analytical technique to the results from said FT-NIR analysis technique;
- analysing the material using an FT-NIR technique;
- and
- identifying and quantifying the type and content of fatty acids present in the material by comparing spectral data obtained from said FT-NIR technique of the material to said calibration matrix.
