Description

  The present invention relates to an oil / fat composition suitable for a plastic oil / fat product such as margarine / shortening, and more particularly to an oil / fat composition suitable for a sand cream.

  Creams (center cream and sand cream) sandwiched between baked products such as cookie cookies and biscuits have hardness (shape retention), oxidation stability (storability), and good texture ( Melting in the mouth is required. Conventionally, in order to obtain the above characteristics, it has been common to use margarine / shortening (hereinafter referred to as M / S) using a partially hydrogenated oil having a high trans fatty acid content.

  However, the causal relationship between trans fatty acids contained in partially hydrogenated oil and heart disease has been clarified, and there is an increasing demand to refrain from using partially hydrogenated oil. As an alternative to partially hydrogenated oil, replacement with palm oil, which can only be stably supplied as vegetable fat, has been carried out. The current situation is that the functions are not fully substituted.

  In order to solve such a problem, utilization of transesterified fats and oils satisfying specific conditions of the middle melting point fraction of palm and fats and oils containing saturated fatty acids having 20 or more carbon atoms as constituent fatty acids (for example, Patent Document 1), special Modifications using a combination of symmetric triglycerides (for example, Patent Document 2) and modifications using an emulsifier (for example, Patent Document 3) are known. However, the modification of triglycerides cannot be achieved by ordinary transesterification methods. The process is complicated and expensive. Moreover, the modification with the emulsifier was not yet functionally satisfied.

Therefore, the use of partially hydrogenated oil to reduce the trans fatty acid content is currently reduced, and the shape retention, storage stability, oxidation stability, and mouth melting are excellent, while the creaming characteristics are excellent. Development of an easy-to-use oil composition for sand cream is required.

Soybean oil (trade name: Soybean white oil, manufactured by Nisshin Oillio Group, P2O content less than 1% by mass, POP content less than 1% by mass, PPO content less than 1% by mass, SSS content less than 1% by mass, linoleic acid and A total content of 57.6% by mass with linolenic acid and a trans acid content of 1.9% by mass was designated as fat C3.

  Table 1 shows fatty acid compositions of fats and oils A1 to A2, B1 to B4, and C1 to C3.

<Oil composition and shortening preparation 1>
Fats and oils A1 and B1 were blended at a ratio shown in Table 2 to prepare an oil and fat composition, and using the prepared oil and fat composition, a shortening with a blowing gas amount of about 10% was produced according to a conventional method. The manufactured shortening was evaluated for creaming property, shape retention, and melting in the mouth according to the following criteria. The results are shown in Table 2.

※ 表中の数値は、ＰＰＯとＰＯＰの比（ＰＰＯ／ＰＯＰ）を除いて質量％

* The values in the table are mass% excluding the ratio of PPO to POP (PPO / POP).

<Oil composition and shortening preparation 2>
The fats and oils A1 to A2, the fats and oils B2 to B4 and the fats and oils C1 to C3 were blended in the ratios shown in Table 3 to prepare an oil and fat composition. Using the prepared fat and oil composition, the amount of blown gas was about 10%. Manufactured a shortening. The manufactured shortening was evaluated for creaming property, shape retention, and melting in the mouth according to the following criteria. The results are shown in Table 3.

※ 表中の数値は、ＰＰＯとＰＯＰの比（ＰＰＯ／ＰＯＰ）を除いて質量％

* The values in the table are mass% excluding the ratio of PPO to POP (PPO / POP).

<Oil composition and shortening preparation 3>
Using the oil and fat composition of Example 6 and Comparative Example 6, 0.5% by mass of polyglycerin fatty acid ester (trade name: SY Glyster PS-3S (HLB2.6), Sakamoto Pharmaceutical Co., Ltd.) as an emulsifier, lecithin (Trade name: lecithin DX, manufactured by Nisshin Oillio Group Co., Ltd.) 0.1% by mass, tocopherol (trade name: Tocopherol 80, manufactured by Nisshin Oillio Group Co., Ltd.) and tea extract (trade name: Sanphenon OD30, Taiyo) 200 ppm of Chemical Co., Ltd. was added, and a shortening with a blown gas amount of about 10% was produced according to a conventional method.
The shortening produced was subjected to a storage test at 30 ° C., and as a result, flavor deterioration was observed in those using Comparative Example 6 after 3 months of storage, but deterioration in flavor was observed in those using Example 6. I couldn't.
From this result, it can be said that the shortening obtained from the oil and fat composition of Example 6 is superior in preservability and oxidation stability as compared with the shortening obtained from the oil and fat composition of Comparative Example 6.

  By using the oil and fat composition of the present invention, a margarine / polyamide having a low trans fatty acid content and excellent in shape retention, storage stability, oxidation stability, and mouth melting, on the other hand, excellent in creaming characteristics and easy to manufacture and handle. Shortening is obtained, and it is particularly suitable for sand cream, so it can be used for a wide range of foods such as confectionery bread.
