PROBLEM TO BE SOLVED: To provide an efficient dry discrimination method for oil and fat in which crystallization rate is enhanced while keeping the purity of a crystal portion high.SOLUTION: In the dry discrimination method for oil and fat, dry discrimination is performed while enhancing the crystallization rate by adding a 4-14C free fatty acid to raw material oil and fat. A crystallization accelerator having the 4-14C free fatty acid as an effective ingredient is also provided. The raw material oil and fat is preferably oil and fat other than lauric-based oil and fat. In the triglyceride composition of the raw material oil and fat, the content of symmetric triglyceride represented by SUS (S is saturated fatty acid and U is unsaturated fatty acid) is 10 mass% or more, and the content of tri-saturated triglyceride (SSS) is 0-10 mass%. |
