Bibliography

ISO 8292-2:2008 specifies an indirect method for the determination of the solid fat content in animal and vegetable fats and oils (hereafter designated "fats") using low-resolution pulsed nuclear magnetic resonance spectrometry.Two alternative thermal pre-treatments are specified: one for general purpose fats not exhibiting pronounced polymorphism and which stabilize mainly in the β'-polymorph; and one for fats similar to cocoa butter which exhibit pronounced polymorphism and stabilize in the β-polymorph. Additional thermal pre-treatments, which may be more suitable for specific purposes, are given in an informative annex.The indirect method is less easy to carry out and less reproducible than the direct method, but is more accurate and more universally applicable to all fats.
