(Industrial Application Field) The present invention relates to a plastic oil composition, which has a plasticity suitable for use in pie and pastry margarine, shortening, and other edible processed oils and fats that require particularly high spreadability (extensibility). It relates to a wide range of oil and fat compositions. (Prior art) Generally, soybean oil, rapeseed oil, corn oil, palm oil, safflower oil, or their hydrogenated oils are used as oils and fats that are required to have the above-mentioned high spreadability and are generally used in margarine, snow toning, etc. It is manufactured by blending it so that it has the consistency (plasticity) of (Problem to be Solved by the Invention) However, it has been pointed out that the temperature range in which the above-mentioned plasticity is maintained appropriately is relatively narrow for such oils and fats, and furthermore, it is difficult to maintain a certain level of shape retention. There was a problem. In other words, the above-mentioned shape retention can be thought of as the heat resistance of oils and fats, and the products that require the above-mentioned spreadability include margarine for pies, pastries, etc. It is highly desirable that the material has appropriate plasticity over the temperature range in which it will be used. For folded dough for pies and pastries, it is necessary for the kneaded flour dough and folded fat to behave in the same way during kneading and to be stretched thinly. This will not result in a good finished product. When the material has appropriate flexibility and maintains its plasticity, by applying appropriate pressure from the outside, the fat and oil is folded into the dough and spreads out as a thin layer, resulting in a unique layered structure. It is said to be essential for oils and fats for Lee (folding oils and fats). It is generally known that oils and fats in which the proportion of solid fat in the fat is about 20 to 40% by weight exhibit good plasticity. Solid fat content (hereinafter also referred to as SFC) indicates the ratio of solid fat to liquid oil at a certain temperature. If the SFC is more than 45% by weight, the oil will become hard and will not elongate easily against external pressure, while if it is less than 15% by weight, it will be too soft and easily dissolve. SFC of 20 to 40% by weight is in a plastic state with appropriate flexibility, which is important for pie, pastry dough, butter cake dough, etc. (Means for Solving the Problems) Here, the present inventors have proposed a method that has a wide usable temperature range and
In other words, as a result of continuous and intensive research into plastic oils and fats used in pie and pastry dough, etc., which have stable spreadability against changes in temperature and mechanical workability, we have found that kapok oil can be hydrogenated under specific conditions. Trans isomer obtained by adding 20
The present invention was completed based on the discovery that by selecting an oil or fat containing at least % by weight, the plasticity range of pie and pastry dough can be significantly expanded in the range of 5 to 30°C. That is, in the present invention, 60 to 90% by weight of the total fat and oil is blended with hydrogenated Kapok oil containing 20% by weight or more of the trans isomer obtained by hydrogenating Kapotsk oil in the presence of a nickel catalyst and having a melting point of 30 to 45°C. This is a plastic oil and fat composition. In the present invention, kapoku oil is a semi-drying oil obtained from the seeds of kapoku trees and is extracted by a pressing method or a pressure extraction method. And their chemical properties are generally iodine value (IV) 85-112, saponification value (SV)
182-196, refractive index n 25 D 1.469-1.473, specific gravity d 25 25 0.915
~0.920. Further, the nickel catalyst was used because it is a catalyst that is practically used in large amounts as a catalyst for hydrogenation of edible oils and fats, and is not a special catalyst. Next, the trans isomer referred to in the present invention is one in which the geometric configuration produced by hydrogenating the above-mentioned kapok oil in the presence of a nickel catalyst forms a trans form compared to the cis form of natural fats and oils. , among the fatty acids that make up fats and oils, saturated fatty acids (double bonds:
It is partially produced in unsaturated fatty acids (with one or more double bonds) other than 0). The above trans isomer detection method is based on the standard oil and fat analysis test method (2.4.24 Isolated trans isomer) established by the Japan Oil Chemists Association, which is commonly used in the oil and fat industry, and the solid fat content is also based on the same standard. According to the oil and fat analysis test method (Temporary solid fat content in 1983). (Function) It is well known that among the oils and fats obtained from the above-mentioned plant seeds, kapok oil has fatty acids with a cyclic structure in its structure. These fatty acids are generally called cyclopropenoic acids and are extremely unstable fatty acids, but in the present invention, by hydrogenating the cyclopropenoic acids, the above-mentioned physical properties, especially spreadability, are significantly affected. This will be improved. (Example) Hereinafter, the present invention will be specifically explained with reference to Examples. Examples 1 to 4 and Comparative Examples 1 to 11 Kapok hydrogenated oil No. 1 was Kapok oil (iodine value
IV96) 2Kg, Nickel catalyst, Unikema (Netherlands) pre-cat PC-9906, 0.5%
(to oil) was added and trans isomerization was carried out at a temperature of 200°C. Decolorize and deodorize as usual to reduce melting point.
36.2℃, laton isomer content 50% by weight, 5℃ and
Kapotsuk hydrogenated oil with a solid fat content of 50% and 28% by weight at 30°C was obtained. Kapok Hydrogenated Oils No. 2 to No. 5 were hydrogenated in the same manner as in Example 1 (Kapoku Hydrogenated Oil No. 1) to obtain Kapok Hydrogenated Oils having the analytical values shown in the table below. Kapotsu hydrogenated oil No. 6 has hydrogenation temperature
The same procedure as in Example 1 was conducted except that the temperature was 140°C. Next, for No. 7 to No. 12, the base oil used is rapeseed oil (IV
= 118), soybean oil (IV = 136), corn oil (IV =
120), the same operation as in Example 1 was carried out. The base oil and fat obtained as above were blended as shown in the table, 824g of the same oil, 160g of water, 12g of salt,
Soybean lecithin 2g, monoglyceride 2g and β
- A small amount of carotene was added and mixed and emulsified to produce margarine with high spreadability using a small margarine production machine. The resulting margarine was aged at 25°C for 2 days, and then its physical properties were evaluated by conventional methods and the results are shown in the table.
