Description

  The present invention relates to fats and oils for emulsified foods that are used in emulsified foods such as margarine, fat spreads, creams, dressings, and flower pastes, and are composed of partially hydrogenated fats and oils with reduced trans-type fatty acids.

Many foods are in an emulsified state and consist of two phases of fats and oils. Among them, water-in-oil emulsified foods in which fine particles comprising an aqueous phase are dispersed in an oil phase include butter and margarine. On the other hand, oil-in-water emulsified foods in which fine particles comprising an oil phase are dispersed in an aqueous phase include milk, cream, ice cream, dressing, soup, sauce (ie, seasoning juice) and the like.
Water-in-oil emulsified foods such as margarine and fat spread require solid plastics and liquid oils with excellent plasticity to maintain their solid state, ease of use, and smooth texture. In particular, partially hydrogenated fats and oils (hereinafter also referred to as hardened oils) have been frequently used.

  In addition, emulsified foods generally called creams are oil-in-water emulsified foods, and those that are used in a liquid state and those that contain bubbles are used. Creams that are used in a liquid state include coffee creams, and recently creams used for desserts and cooked foods, and are topped with desserts such as pudding and jelly. A whipped cream is used as a cream containing bubbles. Conventionally, partially hydrogenated fats and oils have been used in the past, and had the effect of improving emulsification stability and flavor.

  In recent years, excessive intake of trans fatty acids has been promoted to raise LDL cholesterol in blood and lower HDL cholesterol to increase the risk of coronary heart disease. Partial hydrogenation used in these emulsified foods For oil, measures were taken to minimize the amount of trans fatty acids in fats and oils.

  First, in order to reduce trans acid, it has been considered to use a completely hydrogenated fat, so-called extremely hardened oil, as a solid fat. However, because extremely hardened oil has a very high melting point, it cannot be used in a large amount in emulsified foods as conventional partially hydrogenated oils and fats, but it will still be poorly dissolved in the mouth, so more liquid oil must be added to avoid it. There wasn't.

  Therefore, palm oil, a high melting point fraction of palm oil, or lauric oil and fat such as palm oil and palm kernel oil, plant extremely hardened oil, and transesterified oil in various combinations of liquid oil have been used as solid fat. .

  If the transesterified oil is to be replaced with partially hydrogenated fats and oils, the properties of the emulsified food can be made comparable to the conventional ones, but the oxidation stability and flavor are inferior. Milk ingredients such as fresh cream and powdered milk, and various flavor materials such as eggs and vinegar cannot be fully enhanced, and the flavor of flavoring may be reduced.

  For example, transesterified oils containing 10 to 30% by mass of saturated fatty acids having 12 to 12 carbon atoms and 5 to 25% by mass of saturated fatty acids having 18 to 18 carbon atoms are known as plastic fats and oils used in water-in-oil emulsified fats and oils such as margarine. (Patent Document 1).

  Non-selective transesterified oils having a PPP content of 4 to 18% by mass, a PPO + POP content of 15 to 55% by mass, PPO / POP> 1, and (PPO + POP) / PPP> 1.8 are known (patents) Reference 2).

  However, since these oil and fat compositions use transesterified oil and use a large amount of liquid oil and fat, the flavor is insufficient. Moreover, the flavor unique to palm oil appears strongly, which is not desirable.

  In addition, oil-in-water emulsified oils and fats foods such as coffee creams are known to have oil and fat compositions composed of vegetable oils containing high oleic acid (Patent Document 3, Patent Document 4), but these oil and fat compositions have poor milky feeling, Moreover, a sticky texture remains.

As a method for imparting a rich taste like partially hydrogenated oil, for example, there is a plastic fat composition containing 0.5 to 10% by mass of distilled palm oil (Patent Document 5).
However, since fats and oils that are not sufficiently refined are added, there is a disadvantage that the miscellaneous taste remains and the color tone changes due to the addition.

Moreover, it is an oil-fat composition which contains 1-30 mass% of partially hydrogenated fats and oils, and the peroxide value of this partially hydrogenated fats is 0.04-7 (patent document 6). ).
However, because it is a deterioration of fats and oils, it will have a strange odor that should not occur, and when used in processed oils and fats, the original flavor of the foods will be impaired, and the flavor after processing will not be sufficient. Although the trans acid is low, an oil and fat effective for the flavor of the emulsified food has not been obtained.

JP 2007-215521 A JP 2007-177100 A Japanese Patent No. 4003804 JP 2007-274997 A JP 2009-240220 A JP 2009-89684 A

  As described above, the transesterified oils obtained by various combinations of the conventional oils and oils of palm and lauric oils, extremely hardened oils of oils, and liquid oils are inferior in oxidation stability and flavor. There is a problem that some flavor materials such as butter, fresh cream, powdered milk, etc. and various flavor ingredients such as eggs and vinegar cannot be enhanced, and there is a problem that the flavor of flavoring is reduced. The various ideas described above have not yet fully solved this problem.

  Therefore, the invention according to each claim of the present application (hereinafter referred to as the present invention) solves the above-mentioned problems, trans-acid is greatly reduced compared to conventional fats and oils, and is excellent in oxidative stability. The fats and oils for emulsified foods and the emulsified foods using the same are used so that the original flavor and taste of the material used in the above can be utilized, and the added flavoring agent can be enhanced.

The inventors of the present application have partially hydrogenated various fats and oils for use in emulsified foods so as to reduce the trans acid content as much as possible. It has been found that the flavor of an emulsified food can be successfully extracted by passing through a predetermined partial hydrogenation process without the presence of a large amount of acid, and a partially hydrogenated fat and oil excellent in taste and flavor can be produced. It was.
In the process of devising not to generate transacid as much as possible, it was found that partially hydrogenated fats and oils hydrogenated so as to have a specific fatty acid composition solve the above-mentioned problems, and furthermore, have specific SFC characteristics. The present invention has been completed by making it more effective.

  That is, in this invention, it consists of the partial hydrogenation fats and oils which contain 2-10 mass% of trans acids, The content of C18 monounsaturated fatty acid in a total fatty acid is 40 mass% or more, and C18 Total amount of monounsaturated fatty acids having a saturated fatty acid amount of 15% by mass or less, a polyunsaturated fatty acid amount containing 2 or more double bonds in the molecule of 20% by mass or less, and 18 carbon atoms (A ), The oil / fat for emulsified foods prepared so that the mass ratio (T / A) of the monovalent trans acid amount (T) having 18 carbon atoms to 0.02 to 0.1 is occupied.

  The fats and oils for emulsified food according to the present invention configured as described above are partially hydrogenated fats and oils in which trans acid is reduced as much as possible, and at least in the total fatty acids in order to have an action of extracting the flavor and taste of the emulsified foods. The amount of saturated fatty acid having 18 carbon atoms is limited to 15% by mass or less so as to contain 40% by mass or more of monounsaturated fatty acid having 18 carbon atoms and not to deteriorate the flavor and taste of the emulsified food. .

  In addition, by limiting the amount of polyunsaturated fatty acid containing two or more double bonds in the molecule to 20% by mass or less, the oxidation stability is improved, and the flavor and taste are not deteriorated even during storage of fats and oils. Can be held.

  In addition, the mass ratio (T / A) of the amount of monovalent trans acid (T) having 18 carbon atoms to the total mass (A) of monounsaturated fatty acid having 18 carbon atoms is 0.02 to 0.1. This preparation prevents the isomerization of the fatty acid that has been removed from the reaction system after the addition of hydrogen and has not added hydrogen as a result, and the production of trans acid is minimized.

  Moreover, in order to solve the said subject and to draw out the flavor and flavor of emulsified food more, the said total fatty acid contains 70 mass% or more of C18 fatty acids, and C18 monounsaturated fatty acids are contained in 60. The fat or oil for emulsified food according to claim 1 is preferably contained in an amount of not less than mass%.

  Further, in order to draw out the flavor and taste of the emulsified food, the SFC (solid fat content) at 5 ° C. in the above-mentioned oil / fat for emulsified food is 20 or less, and the difference between the SFC at 5 ° C. and the SFC at 20 ° C. is 15 or less. And the melting point is preferably 35 ° C. or lower.

  In order to prevent generation of trans acid as much as possible, the raw materials of the above partially hydrogenated fats and oils are obtained from fractionated oils of rapeseed oil, high oleic rapeseed oil, high oleic safflower oil, high oleic sunflower oil, palm oil and palm oil. It is preferable that it is 1 or more types of fats and oils chosen from the group which consists of.

  Moreover, it is preferable that the above-mentioned partially hydrogenated oil and fat which solves the said subject is the partially hydrogenated oil and fat hydrogenated at 60-90 degreeC for 20 minutes or more in presence of the nickel catalyst.

  And as an emulsified food which solves the said subject, it shall be set as the emulsified food which consists of the margarine, fat spread, cream, dressing, or flour paste which contains the fats and oils for obtained emulsified foods in 5-100 mass% in fats and oils components. Can do.

  In the present invention, trans acid is greatly reduced compared to conventional fats and oils, and also has excellent oxidation stability. When used in emulsified foods, the flavor and taste inherent to the material are produced, so that the added flavoring is enhanced. Oils and fats for emulsified food can be provided. And the emulsified food using the same has an advantage that the body and the mouth melt well.

  The fats and oils for emulsified food according to the present invention comprise partially hydrogenated fats and oils containing 2 to 10% by mass of trans acid, and the content of monounsaturated fatty acids having 18 carbon atoms in the total fatty acids is 40% by mass or more and the number of carbons. The content of 18 saturated fatty acids is 15% by mass or less, and the content of polyunsaturated fatty acids containing 2 or more double bonds in the molecule is 20% by mass or less.

The emulsified food fat according to the present invention is a partially hydrogenated fat containing a large number of monounsaturated fatty acids having 18 carbon atoms, limiting the amount of saturated fatty acids so as not to deteriorate the taste, and further stabilizing the oxidation. In order to improve the properties, the polyunsaturated fatty acid content is reduced as much as possible.
That is, when the monounsaturated fatty acid having 18 carbon atoms is less than 40% by mass and the content of the saturated fatty acid having 18 carbon atoms exceeds 15% by mass, the taste of the emulsified food is attributed to this invention. This is not preferable because it cannot be obtained to the extent expected. Therefore, the C18 monounsaturated fatty acid may be 40% by mass or more, preferably 60% by mass or more, and more preferably 70% by mass or more.
In addition, if the content of polyunsaturated fatty acid containing two or more double bonds in the molecule exceeds 20% by mass, the oxidation stability is not sufficient, and the flavor and taste are deteriorated during storage of fats and oils. It is not preferable because it is easy to make.

In order to minimize the production of trans acids, the isomerization when hydrogen is added to the double bond in the fatty acid is suppressed, and at the same time, the fatty acid is released after the addition of hydrogen and no hydrogen is added. It is important to protect against isomerization.
In order to achieve a partially hydrogenated oil and fat that realizes this, the mass ratio (T / A) of the amount of trans acid (T) in the total amount (A) of monovalent unsaturated fatty acids having 18 carbon atoms is set to 0.02 to 0.02. It should be 0.1.
If the mass ratio (T / A) is less than 0.02, it is preferable to minimize the production of trans acid, but it requires only precise control and does not have practicality necessary for food production. A mass ratio (T / A) exceeding 0.1 is not preferable because the amount of trans acid is not sufficiently reduced to the extent expected by the present invention.

  Representative examples of vegetable oils and fats used as starting materials for partially hydrogenated oils and fats in the present invention include rapeseed oil, rice oil, sunflower oil, olive oil, and palm oil. Particularly preferred oils and fats are those containing 40% by mass or more of monovalent unsaturated fatty acids having 18 carbon atoms and low in polyunsaturated fatty acids. Specific examples thereof include rapeseed oil, high oleic rapeseed oil, and high oleic acid. Safflower oil, high oleic sunflower oil, palm oil and its fractionated oil, and mixtures of two or more thereof are desirable.

  More desirable oils and fats are high oleic rapeseed oil, high oleic acid safflower oil, and high oleic acid sunflower oil. These oils and fats are used as raw materials to carry out partial hydrogenation to obtain monounsaturated carbon atoms of 18 carbon atoms. Partially hydrogenated fats and oils containing 70% by mass or more of fatty acids are obtained.

The hydrogenation reaction is usually carried out under the conditions of 0.05 to 0.5% by mass of nickel catalyst and 0.05 to 0.5 MPa of hydrogen pressure, and the reaction temperature at that time is a condition satisfying the above fatty acid composition. Often, trans acids are not generated as much as possible, and saturated fatty acids are not generated. For that purpose, it is desirable to make it react at the temperature of 60-90 degreeC for 20 minutes or more.
When the reaction temperature range is lower than 60 ° C., the amount of trans acid produced is small, but the hydrogenation reaction becomes extremely slow and the practicality is lowered, which is not preferable. Moreover, when the reaction temperature range is higher than 90 ° C., the reaction rate at which the trans isomer increases increases, which makes it difficult to prepare the desired partially hydrogenated oil of low trans acid, which is not preferable.

In addition, during the hydrogenation reaction, not only does the reaction of fatty acid saturation occur, but it is thought that various trace substances that affect the flavor of fats and oils will also change. Cost. Therefore, in the hydrogenation reaction for less than 20 minutes in the above temperature range, the flavor improving effect by a trace amount substance is not sufficient.
As described above, the monounsaturated fatty acid having 18 carbon atoms is 40% by mass or more, preferably 60% by mass or more, and the polyunsaturated fatty acid is 20% by mass or less. It becomes a partially hydrogenated oil that has excellent oxidation stability at the time and excellent flavor.

Also, it is tasted by replacing part or all of the liquid oil with partially hydrogenated fats and oils whose SFC at 5 ° C is 20 or less, the difference between SFC at 5 ° C and SFC at 20 ° C is 15 or less and the melting point is 35 ° C or less. The body becomes rich and the emulsifiability is improved.
The fats and oils prepared so as to satisfy the above conditions may be used in an optimum amount according to the intended emulsified food, and may be used by mixing with other fats and oils having a low trans acid content. .

  The type of the emulsified food in the present invention is not particularly limited as long as it is a food emulsified so that fats and oils are contained in the fat and oil component in an amount of about 5 to 100% by mass. For example, margarine or fat spread, Creams, dressings, and flower pastes can exert their effects well. In margarine or fat spread, it can be used as a component of solid fat or as a substitute for liquid oil.

Furthermore, in the present invention, transesterified oil or palm oil can be used to strengthen the shape retention, and the cream is used in whipped cream, coffee cream, ice cream, etc. In order to emphasize a refreshing feeling, it is desirable to use a low melting point oil among the oils according to the present invention.
As other solid fats, it is preferable to use transesterified oil, palm oil, or lauric fats and oils. The same applies to dressing and flour paste.

  Moreover, the oil-fat composition for emulsified foods which mix | blended the fats and oils of this invention or other fats and oils and contained 5-100 mass% of the fats and oils of this invention were prepared beforehand, and this was made into the oil phase part of emulsified foods. It can also be used.

  The following examples are prepared, and the evaluation is performed by SFC using standard fat analysis method 2.2.9 solid fat content (NMR method), and melting point is standard fat analysis method 2.2.4.2 melting point. The fatty acid composition was analyzed according to the standard oil analysis method 15-2003, and the trans fatty acid content was analyzed according to the standard oil analysis method 17-2007.
