Scope
This standard specifies a method for directly determining the solid fat content in animal and vegetable oils (hereinafter referred to as oils) using low-resolution pulsed nuclear magnetic resonance (NMR).
The two heat pretreatment methods specified in this standard are suitable for oils that do not exhibit significant homomorphic polymorphism and have a tendency to form β′ crystals, and for oils similar to cocoa butter that exhibit significant homomorphic polymorphism and have a tendency to form β crystals. Appendix C is applicable to other heat pretreatment methods for special purposes.
