Description

  The present invention relates to a plastic oil / fat composition that provides excellent workability, shape retention and mouth-melting feeling when used in a composition having a continuous phase of oil / fat such as margarine and shortening.

Compositions with a continuous phase of oils and fats such as margarine and shortening are required to have workability in a wide temperature range during the manufacture of confectionery, bread, etc. For this purpose, there is no sudden change in hardness due to temperature changes. While it is required that there is no softening even at a temperature higher than normal temperature, it is required to be smoothly stretched by the physical force during work and not to impair the mouth-feeling of foods using a composition with fats and oils as a continuous phase. It has been.
In addition, a composition having a continuous phase of fats and oils such as margarine and shortening is often refrigerated for quality maintenance, and it is necessary to adjust the temperature so that it has an appropriate hardness before work. It is required to have work aptitude that can be used immediately even if it is refrigerated.

  However, it is difficult to combine these contradictory properties. If the difference between the hardness at storage and the appropriate hardness at work is reduced, the meltability is good but the shape retention is not sufficient. It has sex, but the mouthfeel is worse. Further, if emphasis is placed on the feeling of melting in the mouth while maintaining shape retention, there is a problem that the difference between the hardness during storage and the appropriate hardness during work increases, and the workability in a wide temperature range is impaired. Furthermore, while it has been suggested that trans fatty acids contained in partially hardened oils increase LDL cholesterol in the blood and lower HDL cholesterol to cause cardiovascular disease, while suppressing the content of trans fatty acids, It has been extremely difficult to achieve both conflicting properties, and no satisfactory one has been achieved. For this reason, there has been a demand for a method that achieves both workability in a wide temperature range and good physical properties with good mouth-melting feeling while suppressing the content of trans fatty acid.

As a typical method for obtaining such physical properties, a method for adjusting the melting point and SFC (solid fat content) by a combination of used fats and oils, or an emulsifier is not used for emulsification but as a fat solidifying agent or fat thickening agent. How to do is known.
These methods basically give a good mouthfeel by using liquid oil or low melting point oil and fat, and give shape retention by using high melting point oil and emulsifier. However, no studies have been conducted so far on the study of making the medium melting point transesterified oil compatible with workability in a wide temperature range and good physical properties with shape retention.

Patent Document 1 describes a water-in-plastic emulsion for roll-in containing 7 to 16% by weight of extremely hardened oil of Hyelin rapeseed oil. However, the amount of extremely hardened oil is increased for the purpose of normal temperature distribution. Therefore, it has shape retention, but the mouthfeel was not good.

Patent Document 2 describes an oil and fat composition having a continuous phase of an oil and fat such as a butter cream or a plastic oil and fat composition having good heat-resistant shape retention without impairing the melting point and SFC of the fat and oil, and without losing the mouth melting feeling. However, the fats and oils used in the past use a combination of hard stock and low melting point fats and oils that have been used in the past, and since the emphasis is on taste, workability is not satisfactory. There wasn't.

Patent Document 3 describes margarine or shortening containing 30% or more of oil and fat that is liquid at 20 ° C. and containing a polyglycerin fatty acid ester that satisfies a specific condition, but 30% of oil and fat that is liquid at 20 ° C. Because of the above use, the shape retention was not satisfactory.

Patent Document 4 describes a thickener for fats and oils characterized in that the main constituent fatty acid is behenic acid and a polyglycerin fatty acid ester having an esterification degree of 50% or more as an active ingredient. The purpose is to improve the dispersion stability of powdered foods in oil using polyglycerin fatty acid ester to increase the viscosity of the oil, and it is not a plastic oil composition, but oil and fat like margarine and shortening. It is not related to the composition to be a continuous phase.

Japanese Patent No. 5430202 JP 2013-223466 A Japanese Patent No. 4724094 Japanese Patent No. 3497780

  An object of the present invention is to provide a plastic oil and fat composition that provides excellent workability, shape retention and a feeling of melting in the mouth when used in a composition having an oil and fat such as margarine and shortening as a continuous phase.

  As a result of intensive studies, the inventors of the present application have obtained a specific polyglycerin fatty acid ester, a specific polyglycerin fatty acid ester, and a specific fat composition such as margarine and shortening that are excellent in workability and shape retention and excellent in meltability. It has been found that the above-mentioned problems can be solved by the characteristics of the plastic fat composition obtained from the synergistic effect combined with the medium melting point transesterified oil.

That is, in the present invention, first, 95 to 99.9% by mass of a medium melting point transesterified oil satisfying all of (1) to (4) and a saturated fatty acid having a main constituent fatty acid of not more than 5 HLB and having 16 to 22 carbon atoms. It consists of 0.1 to 5% by mass of one or more polyglycerin fatty acid esters which are one or more, dissolves at 70 ° C., stores overnight at 5 ° C., and then has a hardness of 200 to 700 gf stored at 25 ° C. for 4 hours. A plastic fat composition is provided.
(1) SFC is 35-50% at 5 ° C, 15-30% at 20 ° C, and the difference between 5 ° C and 20 ° C is 30 or less.
(2) The melting point is 30 to 45 ° C.
(3) The ratio of the saturated fatty acid and polyunsaturated fatty acid whose trans fatty acid is 1 mass% or less, whose saturated fatty acid having 16 or more carbon atoms is 35 to 50 mass%, and whose constituent fatty acid is 16 or more carbon atoms. Is 1: 0.3 to 1: 0.8.
(4) The hardness after dissolving at 70 ° C. and storing at 5 ° C. overnight and then storing at 25 ° C. for 4 hours is 0 to 150 gf.

2nd invention is a plastic fat composition as described in 1st whose average polymerization degree of the polyglycerol which comprises polyglycerol fatty acid ester is 6-10.

3rd invention is a composition which uses the fats and oils which use the plastic fat composition as described in any one of 1-2 for a continuous phase.

4th invention is a composition which uses the fats and oils whose 3rd composition is shortening, a margarine, or a butter cream as a continuous phase.

  When using a plastic fat composition of the present invention to prepare a composition having a fat and oil such as margarine and shortening as a continuous phase, the shape retention and mouthfeel are good, and the confectionery and bread making work is excellent. Good workability at low temperatures. In particular, when roll-in margarine is prepared, it stretches thinly with the dough, and the produced Danish float becomes extremely good.

  Details of the plastic fat composition according to the embodiment of the present invention will be described below.

First, the transesterified oil constituting the plastic fat composition of the present invention will be described.
In the transesterified oil constituting the plastic fat composition of the present invention, as described in (1) to (4) above, SFC (solid fat content) is a specific value, and the hardness at 25 ° C. is a specific value. A transesterified oil having a specified fatty acid composition having a melting point of 30 to 45 ° C.
Such a transesterified oil can impart workability in a wide temperature range and good mouth-melting feeling to the plastic fat composition of the present invention.

In the transesterified oil, as described in (1) above, the SFC (solid fat content) is 35-50% at 5 ° C, 15-30% at 20 ° C, and the difference between 5 ° C and 20 ° C is 30 or less. It is.
If the difference in SFC between 5 ° C and 20 ° C exceeds 30, the difference between the hardness during storage and the appropriate hardness during work will increase, and workability in a wide temperature range will not be obtained. If it is less than 35% and less than 15% at 20 ° C., sufficient interaction with the polyglycerin fatty acid ester cannot be obtained, and shape retention cannot be imparted.
On the other hand, if the SFC exceeds 50% at 5 ° C., the hardness at the time of storage becomes too hard, and if it exceeds 30% at 20 ° C., the feeling of melting in the mouth becomes worse.

The transesterified oil has a melting point of 30 to 45 ° C. as described in (2) above.
When the melting point is less than 30 ° C., sufficient interaction with the polyglycerin fatty acid ester cannot be obtained, and shape retention cannot be imparted to the plastic fat composition.
On the other hand, if the melting point exceeds 45 ° C, the feeling of melting in the mouth becomes worse.

In the transesterified oil, as described in (3), the trans fatty acid is 1% by mass or less, the saturated fatty acid having 16 or more carbon atoms in the constituent fatty acid is 35 to 50% by mass, and 16 or more carbon atoms. The ratio of saturated fatty acid to polyunsaturated fatty acid is 1: 0.3 to 1: 0.8.
When the saturated fatty acid having 16 or more carbon atoms in the constituent fatty acid is less than 35%, sufficient interaction with the polyglycerin fatty acid ester cannot be obtained, and shape retention cannot be imparted to the plastic fat composition.
On the other hand, when the saturated fatty acid having 16 or more carbon atoms exceeds 50% in the constituent fatty acid, the feeling of melting in the mouth becomes worse.
Moreover, if the ratio of the saturated fatty acid having 16 or more carbon atoms and the polyunsaturated fatty acid is out of 1: 0.3 to 1: 0.8, workability in a wide temperature range cannot be obtained.

In the transesterified oil, as described in (4) above, the hardness after dissolving at 70 ° C., storing at 5 ° C. overnight, and storing at 25 ° C. for 4 hours is required to be 0 to 150 gf.
After dissolving at 70 ° C. and storing at 5 ° C. overnight, storing at 25 ° C. for 4 hours, oils and fats having a hardness of more than 150 gf determined by a specific measurement method described in the examples below are already strong. Therefore, the plastic oil and fat composition is imparted with a property that makes it difficult to melt in the mouth and a property that becomes hard during storage.

In order to obtain the transesterified oil, soybean oil, rapeseed oil, cottonseed oil, rice oil, corn oil, sunflower oil, safflower oil, etc. are used as fats and oils rich in polyunsaturated fatty acids. Rapeseed oil, high oleic sunflower oil, high oleic safflower oil, palm oil, palm fractionated oil, palm kernel oil, coconut oil, beef tallow, lard, etc., and these oils and fats are hydrogenated into extremely hardened oil Are mixed and then subjected to random transesterification.

The method for random transesterification is not particularly limited, and a method using a mixture of sodium methoxide or caustic soda, glycerin and water as a chemical catalyst, or a well-known method using an enzyme lipase can be employed. When lipase is used, it is a lipase having no specificity at the position of triacylglycerol, such as lipase derived from Candida.
After the transesterification reaction, the catalyst is removed, and if necessary, deoxidation and / or decolorization are performed, and further, deodorization is performed to obtain a desired oil and fat.

  Next, the polyglycerin fatty acid ester constituting the plastic fat composition of the present invention will be described.

The polyglycerin fatty acid ester is a polyglycerin fatty acid ester in which the main constituent fatty acid having an HLB of 5 or less is one or more selected from saturated fatty acids having 16 to 22 carbon atoms, and 0.1 to 5 in the plastic fat composition. It is contained by mass.
The term “main constituent fatty acid” as used herein refers to a fatty acid that is 50% by mass or more of the fatty acid composition constituting the polyglycerol fatty acid ester, preferably 70% by mass or more, more preferably 80% by mass or more, and still more preferably. Is 90% by mass or more.
Moreover, the average polymerization degree of the polyglycerol which comprises polyglycerol fatty acid ester becomes like this. Preferably it is 4-12, More preferably, it is 6-10. By containing such a polyglycerin fatty acid ester, without sacrificing workability and good mouthfeel in a wide temperature range provided from the transesterified oil, the plastic fat composition of the present invention. Shape retention can be imparted.
When the HLB of the polyglycerol fatty acid ester exceeds 5, sufficient interaction with the transesterified oil cannot be obtained, and the required increase in hardness cannot be obtained. The same applies to polyglycerol fatty acid esters in which the main constituent fatty acid is one or more selected from saturated fatty acids and unsaturated fatty acids having less than 16 carbon atoms. Moreover, if it is less than 0.1 mass% in a plastic fat composition, sufficient effect will not be acquired, but if it exceeds 5 mass%, a mouth melt feeling will worsen.

Further, the plastic fat composition of the present invention is dissolved at 70 ° C., stored at 5 ° C. overnight, stored at 25 ° C. for 4 hours, and has a hardness of 200 determined by a specific measurement method described in the examples below. ˜700 gf.
With such a plastic fat composition, it is possible to achieve both shape retention at 25 ° C. and good mouth-melting feeling for the composition having the fat of the present invention as a continuous phase.
This shape retention at 25 ° C. is important in a composition having a continuous phase of oil and fat such as margarine and shortening. This temperature range is the initial stage in the fermentation and baking processes for confectionery and bread making, and the shape retention in this temperature range is insufficient for margarine and shortening, that is, the oil is off and the original shape cannot be maintained. If there are such physical properties, the finish such as swelling and texture will be worsened. Similarly, in butter cream applications such as sanding, if there is no shape retention at 25 ° C., problems such as oil oozing out will occur.
The oil and fat containing the transesterified oil and the polyglycerin fatty acid ester are dissolved at 70 ° C., stored at 5 ° C. overnight, and stored at 25 ° C. for 4 hours, and the hardness is less than 200 gf. Sufficient shape retention cannot be imparted to the product, and if it exceeds 700 gf, excessive shape retention will be imparted, resulting in poor mouth melting.

  The plastic fat composition used in the composition having the fat and oil of the present invention as a continuous phase comprises 95 to 99.9% by mass of a medium melting point transesterified oil satisfying all of the above (1) to (4) and a main constituent fatty acid of 5 or less HLB Is composed of 0.1 to 5% by mass of a polyglycerol fatty acid ester selected from saturated fatty acids having 16 to 22 carbon atoms, dissolved at 70 ° C., stored at 5 ° C. overnight, and then at 25 ° C. It is a plastic fat composition having a hardness of 200 to 700 gf stored for 4 hours.

The plastic fat composition that satisfies the above conditions may be used in an optimum amount according to the composition having the desired fat and oil as a continuous phase, and the amount used is not particularly limited, but is preferably 10% by mass. Above, more preferably 15% by mass or more.

  The plastic fat composition of the present invention can provide excellent workability, shape retention and mouth-melting feeling to the composition having a fat and oil as a continuous phase, so that the plastic fat composition can be used alone, As long as this characteristic is not impaired, it can also be used in combination with one or more types of fats and oils listed below.

Examples of oils and fats used include soybean oil, rapeseed oil, cottonseed oil, rice oil, corn oil, sunflower oil, safflower oil, high oleic rapeseed oil, high oleic sunflower oil, high oleic safflower oil, palm oil, palm Nuclear oil, coconut oil, beef tallow, pork tallow, milk tallow and the like can be used. In addition, oils and fats obtained by subjecting these oils and fats to one or more physical or chemical treatments such as hydrogenation, fractionation, and transesterification can also be used.

  The plastic fat composition of the present invention can provide excellent workability, shape retention and mouth-melting feeling to the composition having a fat and oil as a continuous phase, so that the plastic fat composition can be used alone, As long as this characteristic is not impaired, it can also be used in combination with one or more emulsifiers listed below.

As an emulsifier to be used, for example, sorbitan fatty acid ester, sucrose fatty acid ester, lecithin, propylene glycol fatty acid ester, glycerin fatty acid ester, polyglycerin fatty acid ester other than the polyglycerin fatty acid ester, and the like can be used.

  The plastic fat composition of the present invention can be used for shortening, margarine or butter cream by containing other components in addition to the above fats and emulsifiers as necessary.

  As other components to be used, for example, water, alcohol, salt, colorant, acidulant, seasoning, flavor, thickening stabilizer, saccharide, milk component, antioxidant and the like can be used.

・ Evaluation criteria ◎ The squeezed shape is clean and very easy to squeeze. ○ The squeezed shape is clean and requires a little force to squeeze out. △ The squeezed shape is clean but difficult to squeeze out. The squeezed shape is bad and undesirable

As is clear from the results of Example 11 in Table 9, the butter cream according to the claims of the present application comprising a predetermined polyglycerin fatty acid ester and a predetermined transesterified oil and having a predetermined hardness at 25 ° C. Although it was excellent in workability and shape retention, it had a good mouthfeel.
On the other hand, in the comparative example 8 using the palm oil and soybean oil which are natural fats and oils, it was not able to make workability and shape retention property compatible.
