[0097] (a) Preparation Step I of Grease Composition
[0098] The oil and fat composition prepared in the step (a) contains the above-mentioned XXX type triglycerides (one or more types) and X2Y type triglycerides (one or more types) in the above mass %. Specifically, for example, it is obtained through the following steps: XXX type triglycerides (one or more types) having a fatty acid residue X having a carbon number x at positions 1 to 3, and triglycerides having YYY-type triglycerides (one or more types) of fatty acid residue Y with carbon number y are mixed at a mass ratio of XXX-type triglycerides / YYY-type triglycerides at a ratio of 90 / 10 to 99 / 1 to obtain The reaction substrate (here, the aforementioned carbon number x is an integer selected from 8 to 20, the aforementioned carbon number y is an integer selected from x+2 to x+12, and y≤22), the aforementioned reaction substrate is heated, The transesterification reaction is carried out in the presence of a catalyst.

Embodiment 1
[0294] Add 9.9 g of powdering agent A and 0.1 g of (R)-(+)-limonene (manufactured by Kanto Chemical Co., Ltd.) to Laboratory Screw Vial No. 7 (manufactured by As One Corporation), and maintain at 60°C 0.5 hour to completely melt and mix. Here, the usage-amount of a liquid component is 1 mass % with respect to the total mass of a powder composition (powdering agent A+liquid component). Next, the mixture was cooled in a thermostat at 10° C. for 0.5 hours (tempering method), and then left to stand in a thermostat at 20° C. for 12 hours to obtain a powder composition having pores with increased volume.
[0295] The characteristics of the obtained powder composition are as follows.
[0296] Loose bulk density: 0.3g / cm 3
[0297] Average particle size: 121μm
[0298] Expansion rate: 3.9 times
[0299] Such as figure 1 As shown, the powder composition obtained in Example 1 was in powder form.
Embodiment 2
[0301] Add 9.7 g of powdering agent A and 0.3 g of (R)-(+)-limonene (manufactured by Kanto Chemical Co., Ltd.) to Laboratory Screw Vial No. 7 (manufactured by As One Corporation), and maintain at 60°C 0.5 hour to completely melt and mix. Here, the usage-amount of a liquid component is 3 mass % with respect to the total mass of a powder composition (powdering agent A+liquid component). Next, the mixture was cooled in a thermostat at 10° C. for 0.5 hours (tempering method), and then left to stand in a thermostat at 20° C. for 12 hours to obtain a powder composition having pores with increased volume.
[0302] The characteristics of the obtained powder composition are as follows.
[0303] Loose bulk density: 0.3g / cm 3
[0304] Average particle size: 147μm
[0305] Expansion rate: 2.5 times
[0306] Such as figure 1 As shown, the powder composition obtained in Example 2 was in powder form.
