Description

The present invention relates to an edible foamable oil-in-water emulsified oil / fat composition, and a whipped cream to which the composition is whipped and a food containing the same.

Whipped cream is produced by foaming a foamable oil-in-water emulsion. The whipped cream is required to have good flavor, sharp melting in the mouth, and good richness, but in recent years, in addition to these, high freezing storage resistance is also required. That is, even if the whipped cream is stored frozen and then thawed and eaten, it is required to have a good flavor, a sharp melting in the mouth, a good richness, and a fresh texture.

Raw material fats and oils that can be used for whipped cream include lauric-based fats and oils and palm-based fats and oils. When a large amount of lauric oil is added, sharp melting in the mouth and good richness are obtained, and the resistance to freezing storage is increased. On the other hand, the content of saturated fatty acids is increased, which poses a health risk and increases the cost. There is. Although there is a cost advantage when a large amount of whipped cream is added, the resistance to freezing and storage is reduced in the past, and after freezing and thawing, the surface of the whipped cream is liable to crack or crack. There was a problem that the flavor and texture deteriorated.

Patent Document 1 specifies egg yolk lysolecithin and / or egg yolk lecithin for the purpose of preventing the whipped cream from losing its shape, cracking, or tissue roughness, and deteriorating the flavor after cryopreservation and thawing. A foamable oil-in-water emulsified oil / fat composition containing a polyglycerin saturated fatty acid ester having a saturated fatty acid of the above is disclosed.

Japanese Unexamined Patent Publication No. 2014-132884

However, in all the examples of Patent Document 1, a polyglycerin fatty acid ester in which 70% by weight or more of the constituent fatty acids is palmitic acid or stearic acid is used, and transesterified fats and oils are used. In these examples, there are problems that the cost is high, and the whipped cream after cold thawing has poor melting in the mouth and lacks richness. Furthermore, the cured fats and oils contained in most of the examples in the document contain a large amount of trans fatty acids, which is not preferable for health.

An object of the present invention is that, in view of the above situation, cracks and cracks occur even after the whipped cream is frozen and thawed, although it does not substantially contain transesterified oils and fats and trans fatty acids and has a low content of saturated fatty acids. It is an object of the present invention to provide a foamable oil-in-water emulsified oil / fat composition capable of producing a whipped cream which is less likely to occur, has a good flavor and melts in the mouth, has a rich texture, and has a fresh texture.

As a result of diligent research to solve the above problems, the present inventors have substantially not contained ester-exchanged fats and oils and trans fatty acids, and even if the content of saturated fatty acids is suppressed, laurin-based fats and oils are used as fats and oils. A specific amount of palm-based fat and oil containing 45 to 70% by weight of S2U is used, and a specific amount of polyglycerin fatty acid ester to which a specific constituent fatty acid is bound and an emulsifier containing a specific amount of unsaturated fatty acid as a constituent fatty acid are specified. According to the foamable oil-in-water emulsified fatty acid composition in a large amount, cracks and cracks are less likely to occur even after freezing and thawing the whipped cream that has been whipped, and the flavor and melting in the mouth are good, and the food is rich and fresh. We found that we could feel the feeling and completed the present invention.
That is, the first aspect of the present invention is that the content of fats and oils is 25 to 50% by weight and the water content is 45 to 70% by weight in the whole foamable oil-in-water emulsified fat and oil composition.

The content of trans fatty acid is less than 1% by weight, the content of saturated fatty acid is 47 to 65% by weight, and the content of saturated fatty acid in the total constituent fatty acid of polyglycerin fatty acid ester A is 95 to 65% by weight. Polyglycerin fatty acid ester A containing 6 to 25% by weight of saturated fatty acids having 16 and 18 carbon atoms and 55 to 85% by weight of saturated fatty acids having 20 or more carbon atoms at 100% by weight is contained in the entire oil phase. An emulsifier containing 0.1 to 1% by weight and having an unsaturated fatty acid content of 60 to 100% by weight in the total constituent fatty acids of the emulsifier was added to the foamable oil-in-water emulsified oil / fat composition from 0.05 to 0. The present invention relates to a foamable oil-in-water emulsified oil / fat composition containing 5% by weight.

The foamable oil-in-water emulsified oil / fat composition further comprises polyglycerin fatty acid ester B in which the content of saturated fatty acid having 20 or more carbon atoms is 90 to 100% by weight based on the total fatty acids constituting the polyglycerin fatty acid ester B. , It is preferable to contain 0.05 to 1% by weight of the whole oil phase. Further, the foamable oil-in-water emulsified oil / fat composition preferably further contains milk fat in an amount of 5 to 50% by weight based on the total amount of the oil / fat. Preferably, the milk fat is a milk fat derived from fresh cream.

The second aspect of the present invention relates to a whipped cream in which the foamable oil-in-water emulsified oil / fat composition is whipped, and also relates to a food in which the whipped cream is napped, topping, or sanded. The food may be frozen at −40 ° C. to −10 ° C.

According to the present invention, the whipped cream is less likely to be cracked or cracked even after freezing and thawing, despite the fact that it contains substantially no transesterified oil and trans fatty acid and has a low content of saturated fatty acid, and has a flavor. Further, it is possible to provide a foamable oil-in-water emulsified oil / fat composition capable of producing a whipped cream having good melting in the mouth, richness and a fresh texture.

Hereinafter, the present invention will be described in more detail.

If the water content is less than 45% by weight, the emulsion stability may be deteriorated, and if it is more than 70% by weight, it may be difficult to feel the richness of oil in the whipped cream.

The fat and oil contained in the foamable oil-in-water emulsified fat and oil composition of the present invention contains at least a lauric-based fat and oil and a palm-based fat and oil.

The lauric-based oil or fat refers to an oil or fat containing a large amount of lauric acid as a constituent fatty acid, and specifically, an oil or fat having a lauric acid content of approximately 35% by weight or more in the constituent fatty acid may be used, for example, palm kernel oil or coconut oil. Examples thereof include oils, fractionated oils thereof, and extremely hydrogenated oils. The foamable oil-in-water emulsified oil / fat composition of the present invention preferably contains laurin-based oil / fat in an amount of 3 to 50% by weight, more preferably 3 to 45% by weight, based on the total amount of the oil / fat contained in the composition. ~ 40% by weight is more preferable, and 5 to 30% by weight is particularly preferable. If the content of the lauric oil / fat is less than 3% by weight, the whipping time required to prepare the whipped cream becomes long, and the whipped cream in an appropriate state may not be obtained. On the other hand, if it is more than 50% by weight, the cost becomes too high and the surface of the whipped cream may be rough.

The palm oil is a fat derived from palm oil, and it is preferable that S2U is contained in 45 to 70% by weight of the whole palm oil from the viewpoint of foaming property and melting of whipped cream in the mouth.
