The dielectric properties of cacao butter and some other substituted cacao fats were measured. At temperatures below 20°C, the dielectric data of the fats contained symmetrical S
2U glyceride fell down than above 20°C. These tendencies also occurred with coconut oil having S
3 glyceride of low-class saturated fatty acid. It is considered that like this fall due to the glyceride composition of its uniformity.
The dielectric Tan δ at 40°C of these fsts are concerned with containing the quantity of these low-melting fatty acid glyceride such as SU
2 or U
3. In this case these low-melting ones are higher than cacao butter, and unsymmetrical S
2U or S
3 glycerides are lower than cacao butter.
Due to the above phenomena, it was recognized that the glyceride composition quality of substituted cacao fats are generally judging.
About the mixed fats with cacao butter and some other substituted cacao fat, the dielectric properties are different from cacao butter in which the glyceride compositions were not the same as cacao butter. And so it was recognized that analogy of the glyceride composition by measurement of dieletric data of 50:50 mixture could be used.
