Description

  The present invention relates to a water-in-oil emulsified fat composition. The water-in-oil emulsified oil / fat composition of the present invention can be suitably used as a cream for sand filling, topping, etc. of bakery foods.

In oil and fat compositions used as creams for bakery foods such as sand, filling, and topping, many studies have been made on reducing oiliness and improving taste. As a typical method, a method of adjusting the melting point, SFC (solid fat content) and the like of the used fat is known.
Moreover, when using an oil-and-fat composition as a sand cream of bakery food, there existed a problem that the fat-and-oil component contained in an oil-and-fat composition osmose | permeates bakery food and loses commercial value.

  Therefore, Patent Documents 1 to 3 can be cited as prior arts aimed at reducing oiliness, improving meltability in the mouth, and suppressing penetration of fats and oils into bakery foods by using an emulsifier.

  Patent Document 1 describes a high HLB emulsifier-containing oil and fat composition containing a high HLB glycerin fatty acid ester whose fatty acid group is unsaturated, and the oil and fat substantially forming a continuous phase. . Patent Document 2 includes a polyglycerin fatty acid ester having an HLB of 5.5 to 8.5 (provided that the fatty acid residue is unsaturated), and the fats and oils substantially form a continuous phase. An oil and fat composition is described.

  However, when the oil and fat composition obtained in Patent Document 1 is sandwiched in a bakery food, a certain degree of effect was obtained in terms of reducing oiliness and improving mouth melt, but the oil and fat component contained in the oil and fat composition was The problem of penetrating bakery foods has not been solved. Further, the oil and fat composition obtained in Patent Document 2 is not satisfactory in oiliness and dispersibility in the mouth.

  Patent Document 3 is composed of a polyglycerin fatty acid ester characterized in that behenic acid is essential as a constituent fatty acid and is composed of two or more selected from saturated fatty acids and / or unsaturated fatty acids having 8 to 22 carbon atoms. Fat and oil seepage inhibitors are described. However, the oil and fat composition using the oil and fat oozing-out inhibitor described in Patent Document 3 has a problem that the mouth is not melted and the taste is weak.

Accordingly, an object of the present invention is to provide a fat / oil contained in a water-in-oil emulsified oil / fat composition to a bakery food when the water-in-oil emulsified oil / fat composition is used as a cream for sand filling, topping, or the like of a bakery food. The object is to provide a water-in-oil emulsified oil / fat composition capable of suppressing penetration of components.
Another object of the present invention is to provide a water-in-oil emulsified oil / fat composition that has a reduced oily feeling and has a good meltability and taste.

As a result of intensive studies, the present inventors have found that the above problems can be solved by combining and blending two types of emulsifiers having a specific HLB, and have completed the present invention.
That is, the present invention contains a polyglycerol fatty acid ester of HLB 10 or more and a polyglycerol fatty acid ester of HLB 5 or less , and the content of behenic acid is 60% by mass or more in the constituent fatty acid composition of the polyglycerol fatty acid ester of HLB 5 or less. The above object is achieved by providing a water-in-oil emulsified oil / fat composition.

Moreover, this invention is a method of manufacturing the said water-in-oil type emulsified oil-fat composition, Comprising: Polyglyceryl fatty acid ester of HLB10 or more and polyglycerin fatty acid ester of HLB5 or less, This polyglycerin fatty acid ester of HLB5 or less In the constituent fatty acid composition, a water-in-oil emulsified oil / fat composition comprising emulsifying an oil phase having a behenic acid content of 60% by mass or more and an aqueous phase is provided.

  Moreover, this invention provides the foodstuff using the said water-in-oil type emulsified fat composition.

The water-in-oil emulsified oil / fat composition of the present invention, when used as a cream for sand filling, toppings, etc. of bakery foods, permeates the oil / fat components contained in the water-in-oil emulsified oil / fat composition into bakery foods. Can be suppressed.
Moreover, the water-in-oil type emulsified oil / fat composition of the present invention has a reduced oily feeling, and has good meltability and taste.

  Hereinafter, the water-in-oil emulsified oil / fat composition of the present invention will be described in detail based on preferred embodiments.

  The water-in-oil emulsified oil / fat composition of the present invention comprises two types of emulsifiers having different HLBs, that is, a polyglycerin fatty acid ester of HLB 10 or more (hereinafter referred to as polyglycerin fatty acid ester A) and a polyglycerin fatty acid ester of HLB 5 or less. (Hereinafter referred to as polyglycerin fatty acid ester B). In the water-in-oil emulsified oil / fat composition of the present invention, if the polyglycerin fatty acid ester A is not contained, the taste is not easily felt, and if the polyglycerin fatty acid ester B is not contained, it is not preferred. When the product is used as a cream such as a sand filling, topping or the like of bakery food, it is not preferable because the penetration of the fat component contained in the water-in-oil emulsified fat composition into the bakery food cannot be suppressed.

  The HLB of the polyglycerin fatty acid ester A is 10 or more, preferably 11 or more, and more preferably 12-15. In the water-in-oil emulsified oil / fat composition of the present invention, if the HLB of the polyglycerin fatty acid ester A is lower than 10, the water-in-oil emulsification becomes too strong and the taste is not felt, which is not preferable.

  The polyglycerin fatty acid ester A preferably contains oleic acid in its constituent fatty acid composition. The content of oleic acid is preferably 50% by mass or more, more preferably 60% by mass or more, more preferably 70% by mass or more, and most preferably 75 to 100% by mass in the constituent fatty acids of the polyglycerol fatty acid ester A. . In the constituent fatty acid composition of the polyglycerin fatty acid ester A, if the content of oleic acid is less than 50% by mass, a water-in-oil emulsified oil / fat composition with good taste is difficult to obtain.

  When the average degree of polymerization of polyglycerin calculated from the hydroxyl value is n, the number of hydroxyl groups of the polyglycerin is n + 2, and the number of moles of branched fatty acid to be added is M (M / ( n + 2)) × 100 = a value calculated from the esterification rate (%).

  The HLB of the polyglycerin fatty acid ester B is 5 or less, preferably 4 or less, more preferably 1 to 3. In the water-in-oil emulsified oil / fat composition of the present invention, when the HLB of the polyglycerin fatty acid ester B is higher than 5, the water-in-oil emulsified oil / fat composition was used as a cream for sand filling, topping, etc. in bakery foods. In this case, it is not preferable because the penetration of the oil and fat component contained in the water-in-oil emulsified oil and fat composition into the bakery food cannot be suppressed.

In the constituent fatty acid composition of the polyglycerin fatty acid ester B, if the content of behenic acid is less than 60% by mass, an emulsified oil / fat composition having low heat-retaining properties is likely to be obtained. In the present invention, in the constituent fatty acid composition of polyglycerin fatty acid ester B, the higher the content of behenic acid, the better.

  Examples of fatty acids other than behenic acid constituting the polyglycerin fatty acid ester B include lauric acid, palmitic acid, stearic acid, and oleic acid.

  The polyglycerol fatty acid ester B has an esterification rate of preferably 50% by mass or more, more preferably 55% by mass or more, and most preferably 56 to 100% by mass, but the HLB of the polyglycerol fatty acid ester B is 5 or less.
