Description

Fat and oil composition for making snack
Technical Field
The present invention relates to an oil and fat composition for producing a snack. The present invention also relates to an oily snack containing the fat and oil composition for a snack, and a method for producing the fat and oil composition for a snack.
Background
With the diversification of consumer's tastes, snacks having various tastes are required, and there are various demands for fats and oils that greatly affect the physical properties of snacks. For example, in chocolate, fat and oil account for 1/3 to 1/2 of the constituent components, and the texture and meltability in the mouth of chocolate greatly depend on the properties of fat and oil.
In the production of an oily confectionery such as chocolate, one of fats and oils widely used as confectionery fats and oils is cacao butter (hereinafter, also referred to as "CB"). The more the amount of CB blended, the more the resulting confectionery has a rich body rich in cocoa flavor. On the other hand, from the viewpoint of improving the physical properties of an oily snack, it is widely known to produce an oily snack by using a fat for snack, called hard butter, which is made from a fat other than CB in combination with CB. Hard butter is widely used because it is classified into heat-treated type hard butter and non-heat-treated type hard butter according to the use and usage, and the latter non-heat-treated type hard butter does not require heat treatment as a technique for adjusting the crystalline state of fat in the production process, and can improve handling properties and storage properties.
The non-heat-treated hard butter is roughly classified into lauric acids and non-lauric acids. Among the non-modified hard butter, lauric acid hard butter uses oils and fats containing a large amount of short-chain fatty acid residues, and has the advantages of low melting point and good melting feeling in the mouth. On the other hand, the compatibility with CB is low, and the compounding amount of CB is limited to an extremely low level. As described above, in an oil-based confectionery such as chocolate, a preferable cocoa flavor can be obtained as the amount of CB added is higher. However, when an oily confectionery is produced using a lauric hard butter, if the CB content in the oil component contained in the oily confectionery is increased, white spots called bloom due to coarse oil crystals and the like are generated, and the appearance of the oily confectionery is impaired, and the flavor and texture are easily impaired. Therefore, in the oil center using lauric acid hard butter, the amount of CB blended tends to be extremely low, i.e., about 5%. On the other hand, non-lauric hard butter uses an oil or fat containing a large amount of long-chain fatty acid residues as compared with lauric hard butter, has high compatibility with CB, and can give an oily snack with a strong cacao flavor, but tends to have difficulty in obtaining a good mouth-melting feeling as in lauric hard butter.
Non-heat-treated hard butter is roughly classified into: high trans fatty acids containing a large amount of trans-type unsaturated fatty acids and low trans fatty acids containing little trans-type unsaturated fatty acids. The hard butter having a high trans fatty acid content has high compatibility with CB, and therefore an oily snack having a strong cocoa flavor can be obtained.
However, in recent years, oils and fats containing trans-type unsaturated fatty acid residues have been pointed out to be harmful to health, and it is necessary to suppress the intake of trans-type unsaturated fatty acids, and therefore hard butter using high trans-fatty acids and hard butter using low trans-fatty acids have been worldwide preferred.
Therefore, recently, various developments have been made to realize a non-heat-treated hard butter (and a non-heat-treated hard butter in which a trans-acid-type unsaturated fatty acid residue is suppressed as low as possible) that exhibits a good feeling of melting in the mouth and also has good CB compatibility. For example, patent document 1 discloses a non-heat-treated hard butter in which a slightly hydrogenated oil of an oil-and-fat rich in SUS type triglycerides and an oil-and-fat rich in SSU type triglycerides are mixed. Further, patent documents 2 and 3 disclose non-heat-treated hard butter in which the composition of constituent fatty acids and triglycerides is adjusted.

Disclosure of Invention
Technical problem to be solved by the invention
Although the techniques of patent documents 1 to 3 have the effect of slightly improving the mouth-melt feeling and the CB compatibility, for example, when the CB content in the oil or fat component is increased to about 10%, it is found that the frost formation occurs during long-term storage, and there is still room for improvement. Further, the hard butter described in patent document 1 contains a large amount of trans-type unsaturated fatty acids, and thus cannot sufficiently satisfy recent requirements for suppressing the intake of trans-fatty acids.
Therefore, in the 1 st aspect of the present invention, the technical problem is that: provided is an oil and fat composition for confectionery, which can give an oily confectionery that has excellent bloom resistance during long-term storage and that exhibits sufficient mouth-melt feeling and crispness even when the CB content is increased to such an extent that the cocoa flavor can be favorably perceived.
On the other hand, with the diversification of consumer preferences, there are increasing snack products (hereinafter, also referred to as "combined snacks") obtained by combining chocolate with baked snacks such as cookies. In such a combined snack, a balance of the melting sensation in the mouth of chocolate and the melting sensation in the mouth of a baked snack is required. Even if chocolate has a good mouth-melting feeling, and even if a baked snack has a good mouth-melting feeling, one of the chocolate and the baked snack melts earlier than the other (and thus only one of the chocolate and the baked snack remains in the mouth), a flavor having a sense of unity cannot be obtained.
Therefore, the technical problem of the invention according to claim 2 is that: provided is an oil and fat composition for a baked confectionery, which can give an oily confectionery that has excellent bloom resistance during long-term storage and that, when combined with a baked confectionery, exhibits a mouth-melting sensation that matches the mouth-melting sensation of the baked confectionery, even when the CB content is increased to such an extent that the cocoa flavor can be perceived well.

The following describes the conditions (1) and (2) satisfied by the fat and oil composition for snack manufactured in item 1.
Condition (1)
The condition (1) relates to the content of the fat (a). The fat and oil composition for a snack made in the 1 st embodiment has a fat and oil (A) content of 80% by mass or more, based on 100% by mass of the total oil phase.
The content of the fat or oil (a) is preferably 82 mass% or more, 84 mass% or more, 85 mass% or more, 86 mass% or more, 88 mass% or more, or 90 mass% or more, from the viewpoint of achieving an oily snack which has excellent bloom resistance during long-term storage even when the CB content is increased, and which also exhibits sufficient mouth-melt feeling and brittleness. The content of the fat or oil (a) is more preferably high from the viewpoint of further achieving the effects of the present invention, and may be, for example, 92 mass% or more, 94 mass% or more, 95 mass% or more, 96 mass% or more, 98 mass% or more, or 99 mass% or more. The upper limit of the content of the fat or oil (a) is not particularly limited, and may be 100 mass%.

Condition (2)
The condition (2) relates to the La content in the constituent fatty acids. The fat and oil composition for snack made in item 1 had a La content of 20 mass% or more, assuming that the total amount of constituent fatty acids was 100 mass%.
The No. 1 fat and oil composition for a snack is preferably a fat and oil composition for a snack having a high lauric acid content. In the fat and oil composition for confectionery of the present invention having such a high lauric acid content, even when the CB content in the oil phase is increased to 10 mass% or more as described below, the occurrence of blooming during long-term storage can be suppressed. The La content is preferably 22 mass% or more, and more preferably 24 mass% or more or 25 mass% or more. The upper limit of the La content is preferably 40 mass% or less or 35 mass% or less from the viewpoint of further achieving the effects of the present invention.
Taking such La content as an example, an appropriate fatty acid component described later and a fatty acid component of the oil phase of the fat and oil composition for confectionery 1 can be measured by capillary gas chromatography based on "standard fat and oil analysis test method 2.4.2.3 to 2013 defined by japan oil chemical society" and "standard fat and oil analysis test method 2.4.4.3 to 2013 defined by japan oil chemical society". The fatty acid components represented in the present invention are based on: the values obtained were measured by capillary gas chromatography based on "the japan oil chemical society established standard oil analysis test method 2.4.2.3-2013" and "the japan oil chemical society established standard oil analysis test method 2.4.4.3-2013".
Other suitable conditions
The fat and oil composition for snack preparation 1 preferably satisfies the following conditions concerning the oil phase component, in addition to the above conditions (1) and (2). Thereby, it is possible to further realize: the present invention provides an oily snack which has excellent bloom resistance even when stored for a long period of time with an improved CB content and which has a sufficient melt feeling in the mouth and is brittle.
In the fat and oil composition for snack made in item 1, the fat and oil (a) preferably satisfies the following oil phase components.
In the fat or oil (a), the unsaturated fatty acid content is preferably less than 20 mass%, more preferably 18 mass% or less, 16 mass% or less, or 15 mass% or less, assuming that the total amount of the constituent fatty acids is 100 mass%. Therefore, in a preferred embodiment, the content of unsaturated fatty acids in the constituent fatty acids of the fat or oil (a) is less than 20% by mass. When the unsaturated fatty acid content is in the above range, it is preferable to use a fat or oil (a-1) and a fat or oil (a-2) as raw materials of the fat or oil (a) having a low unsaturated fatty acid content.
Among them, it is preferable that the content of unsaturated fatty acids in the constituent fatty acids of the fat or oil (a) is 15% by mass or less (that is, the content of saturated fatty acids in the constituent fatty acids exceeds 85% by mass), since an oily snack having very excellent bloom resistance during long-term storage can be realized even when the CB content is increased.
The lower limit of the unsaturated fatty acid content is not particularly limited, but is preferably 5% by mass or more or 10% by mass or more.
In the fat or oil (a), the total content of P and St is preferably 30 mass% or more, assuming that the total amount of the constituent saturated fatty acids is 100 mass%. As described above, the fat and oil composition for confectionery of the present invention is preferably a type having a high lauric acid content, and the effect of the present invention can be further achieved by containing a relatively long-chain fatty acid such as P or St in the above-described preferred range. The total content of P and St is more preferably 35 mass% or more, 40 mass% or more, 45 mass% or more, or 50 mass% or more. The upper limit of the total content of P and St is preferably 65 mass% or less, and more preferably 60 mass% or less.

Since it is easy to adjust the oil phase component of the fat or oil (a) to the more suitable range described above, it is preferable to use S constituting SSS triglyceride in combination as described above a S b S c The triglyceride contents are within a certain range of each otherRandom interesterified fats (1) and random interesterified fats (2) which differ in degree by 2. In the case of combined use, suitable amounts thereof are as described above.
The obtained transesterified oil or fat may be subjected to fractional distillation within a range not to impair the effects of the present invention. Examples of the fractionation treatment include: known treatments such as wet fractionation using a solvent such as acetone or hexane, and dry fractionation without using a solvent are used.
The method for producing a fat and oil composition for snack products of item 1 comprises: using the thus prepared fat or oil (a), the amount of the fat or oil (a) to be blended is adjusted so that the content of the fat or oil (a) in the oil phase is 80 mass% or more.
The preferable range of the content of the fat or oil (a) in the oil phase may be a range in which components other than the fat or oil (a) in the fat or oil composition for confectionery can be blended, as described in the above section [ fat or oil composition for confectionery ].

First, an oil-and-fat complex in which the content of saturated fatty acid, the content of La, and the total content of P and St in the constituent fatty acid components are preferably within the above-described preferred ranges is prepared. When the oil-and-fat complex is prepared so that the content of the saturated fatty acid having 20 or more carbon atoms is in the above-mentioned preferred range, the condition (3) is easily adjusted to the preferred range, and is therefore preferred.
The oil or fat used for preparing the oil or fat complex is not particularly limited, and the oil or fat complex may be prepared by mixing one or more kinds of oils or fats obtained by subjecting a vegetable oil or fat such as palm oil, palm kernel oil, coconut oil, corn oil, olive oil, cottonseed oil, soybean oil, rapeseed oil, rice oil, sunflower oil, safflower oil (saflower oil), cocoa butter, shea butter, mango kernel oil, monkey fat, and horse fat, or animal oils and fats such as beef tallow, milk fat, lard, fish oil, and whale oil, and by subjecting these oils or fats to one or more kinds of treatments selected from hydrogenation, fractionation, and transesterification.
Next, the oil-and-fat complex obtained by the preparation is subjected to transesterification to obtain a transesterified oil.
The transesterification may be a random transesterification or a site-specific transesterification, and the transesterification based on the random transesterification is preferable because the triglyceride component can be easily adjusted to the above-mentioned suitable form and range, for example, in the above-mentioned condition (2).
When the transesterification is carried out, a chemical catalyst or an enzyme can be used, and examples of the chemical catalyst or the enzyme are as described for the fat and oil composition for snack production 1.
The transesterified fat or oil may be purified. The purification method and conditions were as described for the fat and oil composition for snack preparation No. 1.
The fat and oil composition for snack food 2 may be the transesterified oil itself obtained therefrom, or may be a mixture of 2 or more kinds of the transesterified oils obtained therefrom. It is preferable to mix 2 or more kinds of the obtained transesterified oils because the fat and oil composition for confectionery satisfying all of the above conditions (1) to (3) can be easily produced.
The obtained transesterified oil may be subjected to a fractionation treatment as long as all of the conditions (1) to (3) are satisfied. Examples of the fractionation treatment include: known treatments such as wet fractionation using a solvent such as acetone or hexane, and dry fractionation without using a solvent are used.
The fat and oil composition for confectionery manufactured in item 2 may contain a fat and oil other than transesterified oil (hereinafter, also referred to as "other fat and oil") as long as all of the above conditions (1) to (3) are satisfied. Examples of other fats and oils and the contents thereof may be the same as those described for the fat and oil composition for snack food of item 1.
The fat and oil composition for confectionery manufactured in item 2 may contain other components within a range that can achieve the effects of the present invention. Examples of other components and their contents may be the same as those described for the fat and oil composition for snack food No. 1.
The fat and oil composition for refreshments of item 2 can provide an oily snack having excellent bloom resistance during long-term storage even when the CB content is increased to such an extent that the cocoa flavor can be favorably perceived. The fat and oil composition for a snack according to item 2 can also give an oily snack exhibiting a good melt feeling in the mouth, and can give an oily snack exhibiting good heat resistance. Therefore, the fat and oil composition for confectionery manufactured in item 2 is suitable for oily confectionery such as butter-based confectionery including chocolate, icing, and sweetened butter slurry, and is particularly suitable for chocolate.
The 2 nd fat and oil composition for a baked snack also can provide a mouth-melting sensation that matches the mouth-melting sensation of a baked snack in a combined snack with a baked snack. Therefore, the 2 nd fat and oil composition for a snack is suitable for a combined snack of an oily snack and a baked snack.
The fat and oil composition for confectionery manufactured in item 2 can be used suitably for chocolate, particularly non-modified chocolate not requiring modification, and as a non-modified hard butter composition. When the No. 2 confectionery oil-and-fat composition is used as a non-heat-treated hard butter composition, the CB content in the oil phase can be increased to, for example, 10 mass% or more, 15 mass% or more, and 20 mass% or more while suppressing the occurrence of bloom during long-term storage. In the present specification, "oil phase" and "oil and fat component" mean that oil-soluble components are contained in addition to triglycerides.
The fat and oil composition for snack preparation of item 2 is suitable for butter-based products, as described above. For example, it applies to: creamers for coating, creamers for filling, creamers for topping, creamers for spreads and the like. By using the oil and fat composition for confectionery 2 as in the oil and fat composition for confectionery 1, good heat resistance can be obtained, and for example, a state in which stickiness is suppressed can be maintained even when the composition is brought into contact with a food after storage at a certain temperature, and therefore, the oil and fat composition for confectionery 2 is particularly suitable for: creams for coating.
