On measuring Solid Fat Index (S.F.I.) there are many defects in the usual measuring methods such as A.O.C.S. and J.O.C.S. (Part 1) tentative methods. For example, the operator cannot easily obtain the reliable data with A.O.C.S. method because the fat samples cannot be solidified below 0°C, and mercury employed in J.O.C.S. (1) method is toxic and has a disadvantage of waste water pollution. So, the authors investigated a few measuring methods free from the above-mentioned defects. The modified method that the authors have establised employs a CaCl2 aqueous dye solution (30.4wt%) as a sealing liquid and the same type of dilatometer is used as that in J.O.C.S. (1) method. In this modified method the disadvantages of water pollution are eliminated.
