The powdery fats and oils in the present invention are powdery solid fats and oils at room temperature (20° C.). The melting point of the powdered oil is preferably 25°C or higher and 50°C or lower, more preferably 25°C or higher and 45°C or lower, even more preferably 25°C or higher and 40°C or lower, and even more preferably 25°C or higher and 35°C or higher. ℃ or less.

If the melting point of the powdery oil is within the above numerical range, it will easily melt when used on the skin, and heat will be removed from the skin, making it easier to feel a cooling sensation.
　粉末状油脂は、通常、板状結晶または球状結晶の形態を有し、好ましくは、板状結晶の形態を有する。粉末状油脂は、例えば、５０～４００μｍ、好ましくは５０～３００μｍ、より好ましくは５０～２５０μｍ、さらに好ましくは５０～２００μｍの平均粒径（有効径）を有する。ここで、当該平均粒径（有効径）は、粒度分布測定装置（例えば、日機装株式会社製　Ｍｉｃｒｏｔｒａｃ　ＭＴ３３００ＥｘＩＩ）でレーザー回折散乱法（ＩＳＯ１３３２０１、ＩＳＯ９２７６－１）に基づいて、乾式測定により測定した値（ｄ５０）である。有効径とは、測定対象となる結晶の実測回折パターンが、球形と仮定して得られる理論的回折パターンに適合する場合の、当該球形の粒径を意味する。このように、レーザー回折散乱法の場合、球形と仮定して得られる理論的回折パターンと、実測回折パターンを適合させて有効径を算出しているので、測定対象が板状結晶であっても球状結晶であっても同じ原理で測定することができる。 The powdered fat usually has the form of plate crystals or spherical crystals, preferably the form of plate crystals. The powdery fat has an average particle size (effective diameter) of, for example, 50 to 400 μm, preferably 50 to 300 μm, more preferably 50 to 250 μm, still more preferably 50 to 200 μm. Here, the average particle diameter (effective diameter) is a value measured by dry measurement based on a laser diffraction scattering method (ISO133201, ISO9276-1) with a particle size distribution measuring device (for example, Microtrac MT3300ExII manufactured by Nikkiso Co., Ltd.) ( d50). The effective diameter means a spherical particle size when the measured diffraction pattern of the crystal to be measured matches the theoretical diffraction pattern obtained by assuming a spherical shape. In this way, in the case of the laser diffraction scattering method, the effective diameter is calculated by matching the theoretical diffraction pattern obtained by assuming a spherical shape with the actually measured diffraction pattern. Even spherical crystals can be measured on the same principle.

　上記工程（ａ）又は（ｂ）で得られた溶融状態の油脂組成物は、さらに冷却されて粉末状油を形成する。
　ここで、「溶融状態の油脂組成物を冷却」とは、溶融状態の油脂組成物を、当該油脂組成物の融点より低い温度に保つことを意味する。「油脂組成物の融点より低い温度」とは、例えば、当該融点より１～３０℃低い温度、好ましくは当該融点より１～２０℃低い温度、より好ましくは当該融点より１～１５℃低い温度である。溶融状態にある油脂組成物の冷却は、例えばｘが８～１０のときは最終温度が、好ましくは１０～３０℃、より好ましくは１５～２５℃、更に好ましくは１８～２２℃の温度になるように冷却することによって行われる。冷却における最終温度は、例えばｘが１１又は１２のときは、好ましくは３０～４０℃、より好ましくは３２～３８℃、更に好ましくは３３～３７℃である。上記最終温度において、例えば、好ましくは２時間以上、より好ましくは４時間以上、更に好ましくは６時間～２日間静置することが適当である。特に以下の（ｃ）工程を使用しない場合、例えば２～８日間、具体的には３～７日間、より具体的には約６日間静置しなければならない場合もある。 (d) Step of cooling the melted fat composition to obtain a powdered fat composition The melted fat composition obtained in the above step (a) or (b) is further cooled to form a powdered oil. do.
Here, "cooling the melted fat composition" means keeping the melted fat composition at a temperature lower than the melting point of the fat composition.

In particular, when the following step (c) is not used, it may be necessary to stand still for, for example, 2 to 8 days, specifically 3 to 7 days, more specifically about 6 days.
（ｃ）粉末生成促進工程
　さらに、上記工程（ａ）又は（ｂ）と（ｄ）との間に、（ｃ）粉末生成を促進するための任意工程として、工程（ｄ）で使用する溶融状態の油脂組成物に対し、シーディング法（ｃ１）、テンパリング法（ｃ２）及び／又は（ｃ３）予備冷却法による処理を行ってもよい。これらの任意工程（ｃ１）～（ｃ３）は、いずれか単独で行ってもよいし、複数の工程を組み合わせて行ってもよい。ここで、工程（ａ）又は（ｂ）と工程（ｄ）との間とは、工程（ａ）又は（ｂ）中、工程（ａ）又は（ｂ）の後であって工程（ｄ）の前、工程（ｄ）中を含む意味である。
　シーディング法（ｃ１）及びテンパリング法（ｃ２）は、粉末状油脂の製造において、溶融状態にある油脂組成物をより確実に粉末状とするために、最終温度まで冷却する前に、溶融状態にある油脂組成物を処置する粉末生成促進方法である。
　ここで、シーディング法とは、粉末の核（種）となる成分を溶融状態にある油脂組成物の冷却時に少量添加して、粉末化を促進する方法である。具体的には、例えば、工程（ｂ）で得られた溶融状態にある油脂組成物に、当該油脂組成物中のＸＸＸ型トリグリセリドと炭素数が同じＸＸＸ型トリグリセリドを好ましくは８０質量％以上、より好ましくは９０質量％以上含む油脂粉末を核（種）となる成分として準備する。この核となる油脂粉末を、溶融状態にある油脂組成物の冷却時、当該油脂組成物の温度が、例えば、最終冷却温度±０～＋１０℃、好ましくは＋５～＋１０℃の温度に到達した時点で、当該溶融状態にある油脂組成物１００質量部に対して０．１～１質量部、好ましくは０．２～０．８質量部添加することにより、油脂組成物の粉末化を促進する方法である。

Any of these optional steps (c1) to (c3) may be performed alone, or a plurality of steps may be combined. Here, between step (a) or (b) and step (d) means during step (a) or (b), after step (a) or (b) and in step (d) It is meant to include before and during step (d).

A method of promoting powder formation for treating certain fat and oil compositions.
Here, the seeding method is a method for promoting powderization by adding a small amount of a component that serves as the nucleus (seed) of the powder when cooling the oil-and-fat composition in a molten state. Specifically, for example, XXX-type triglycerides having the same number of carbon atoms as XXX-type triglycerides in the oil-and-fat composition are added to the melted oil-and-fat composition obtained in step (b), preferably 80% by mass or more, more Preferably, an oil powder containing 90% by mass or more is prepared as a core (seed) component. When the core oil powder is cooled, the temperature of the oil composition reaches, for example, the final cooling temperature ±0 to +10 ° C., preferably +5 to +10 ° C. A method of promoting pulverization of the oil and fat composition by adding 0.1 to 1 part by mass, preferably 0.2 to 0.8 part by mass, with respect to 100 parts by mass of the oil and fat composition in the molten state. is.
The tempering method refers to cooling the oil and fat composition in a molten state, once before standing at the final cooling temperature, to a temperature lower than the cooling temperature in step (d), for example, 5 to 20 ° C. lower temperature, preferably 7 Cooling to a temperature lower by about 15°C, more preferably lower by about 10°C, preferably for about 10 to 120 minutes, more preferably about 30 to 90 minutes, is a method of promoting pulverization of the oil and fat composition.
(c3) The pre-cooling method is that the melted oil and fat composition obtained in the step (a) or (b) is cooled in the step (d), and the This is a method of once pre-cooling at a temperature lower than the temperature of the molten state and higher than the cooling temperature in step (d). The temperature higher than the cooling temperature in step (d) is, for example, a temperature higher than the cooling temperature in step (d) by 2 to 40°C, preferably 3 to 30°C, more preferably 4 to 30°C, More preferably, the temperature may be about 5 to 10°C higher. As the pre-cooling temperature is set lower, the main cooling time at the cooling temperature in step (d) can be shortened. That is, unlike the seeding method and the tempering method, the pre-cooling method is a method that can accelerate the pulverization of the oil-fat composition simply by lowering the cooling temperature in stages, and is highly advantageous for industrial production.
