DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beverage such as coffee or tea having a milky flavor. More specifically, the present invention relates to milk-flavored coffee and milk-flavored tea in a closed container, and relates to a milk-flavored beverage in which generation of a deterioration odor derived from milk is suppressed even when stored in a heated state such as a hot bender.

[0002]

2. Description of the Related Art Conventionally, canned beverages in a closed container such as canned coffee and canned tea, which are sold by heating at a hot bender or the like,
Since it is stored at a high temperature for a long time, various problems occur.

For example, as a countermeasure against a problem that occurs when canned coffee or the like is stored in a heated state, Japanese Patent Laid-Open No. 6-245 is disclosed.
In order to prevent the precipitation of milk protein and the separation of fat which occur when canned coffee or the like is stored in a heated state as in the invention of Japanese Patent Publication No. 703, a sucrose fatty acid is added to a coffee extract containing dairy products. A method of adding an emulsifier such as an ester and microcrystalline cellulose is known.

As a countermeasure against the problem of generation of a characteristic deterioration odor derived from milk when canned coffee or the like is stored in a heated state, Japanese Patent Application No. Hei 6-1877 filed by the present applicant.
There is No. 13. The present invention suppresses the deterioration odor and / or color tone change during high-temperature storage by adding a calcium salt to a milk-containing beverage. However, this technique uses a substance that causes the generation of a milk-derived deterioration odor. Is not intended to be selectively removed.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to specify a causative substance of a deteriorating odor derived from milk, to exclude the substance, or to select and use a reduced raw material so that cans at the time of warm storage can be used. It is intended to enhance the stability of milk-flavored beverages such as coffee and canned tea beverages.

[0006]

Means for Solving the Problems The present inventor studied the cause of the deterioration odor that occurs when coffee or tea beverages containing milk are stored in a heated state like a hot bender, and found that milk fat originated from milk fat. It has been found that the lower intermediate fatty acids, especially fatty acids having 10 or less carbon atoms, are decomposed and released during preservation under heating, resulting in a deterioration odor peculiar to milk.

[0007] Incidentally, the fatty acid composition in ordinary milk is as shown in Table 1 below.

[Table 1] Source: "Deterioration of oil and fat foods and their prevention" (Koshobo)

Accordingly, the present invention relates to capric acid (having 1 carbon atom).
0) The use of fats having a total amount of fatty acids having 80% or less of the total amount of fatty acids having a lower carbon number or lower than that of milk, thereby reducing or avoiding the generation of degraded odor caused by the lower intermediate fatty acids. Is what you do.

That is, a first aspect of the present invention is to replace (A) a fat content of which the total amount of fatty acids having 10 or less carbon atoms is 80% by weight or less of milk with (B) a non-fat milk solid content with milk. The present invention relates to a milk-flavored beverage characterized by containing as a component.

If the total amount exceeds 80% by weight of that of milk, the effect of suppressing deterioration odor is almost lost. Said total amount is preferably not more than 50% by weight of that of milk, particularly preferably not more than 30% by weight of that of milk.

The second aspect of the present invention relates to a milk-flavored beverage having a total lactose content of 1% by weight or less, preferably 0.5% by weight or less in the milk substitute component.

The fat having the total amount of the fatty acid having 10 or less carbon atoms of the component (A) of not more than 80% by weight of that of milk is obtained by partially cutting low and middle fatty acids in milk such as milk. For example, fresh cream, fresh cream emulsion and the like can be mentioned. Examples of the component (A) include vegetable fats and fresh creams thereof. Generally, vegetable fats contain about 1.0% by weight of lactose and fresh creams contain about 3.0% by weight of lactose.

The composition of vegetable fat is as shown in Tables 2 to 4 below.

[0014]

[Table 2] Note: All figures in the column of each oil in the table are% by weight.

[0015]

[Table 3]

[0016]

[Table 4]

The use of the non-fat milk solid component (B) is as follows:
(A) Since the fat content of the component alone lacks the richness and flavor of milk, the addition of non-fat milk solids containing milk protein and the like provides milky feeling, body feeling, richness,
It succeeded in imparting flavor. Examples of the non-fat milk solids include milk protein concentrates and skim milk powder. The milk protein concentrate is a concentrate obtained by removing lactose, minerals, water and the like, which are ultrafiltration membrane-permeable components, from skim milk. Therefore, the milk protein concentrate does not contain lactose, and very little even if it is contained in kari.

[0018] The content of lactose in milk varies somewhat depending on the production area, feed, etc., but is usually 4.
In the second invention, the lactose content of 1% by weight or less means that the amount of lactose is 25% by weight or less in the case of using normal milk. This means that the weight was reduced to less than% by weight.

It is preferable that lactose is not contained at all in the above-mentioned components, but it is desirable that at most 1% by weight or less, preferably 0.5% by weight or less. As shown in FIG. 2, the presence of lactose is not preferred because it significantly increases the amount of formic acid produced and causes sourness and astringency in the product.

As a product from which milk sugar is excluded from milk components, there is a milk protein concentrate, which is preferably used as the component (B).

The amount of the fat not containing the lower middle fatty acid is as follows:
Can be added in an amount corresponding to the fat content of milk, but in coffee and tea, besides these milk substitutes, sweeteners, emulsifiers, baking soda and other additives used in the production of canned coffee and canned tea Therefore, it is preferable to consider the amount of lactose contained in these additives. In addition, it is preferable that these additives do not contain disaccharides other than monosaccharides and / or lactose. The amount of total lactose contained in the whole milk-flavored beverage of the present invention is desirably 1% by weight or less, preferably 0.5% by weight or less.

As the sweetener, sugar can be used, but sugar alcohols and / or non-saccharide sweeteners (diterpene glycosides) can be used for people who are on a diet.
It is preferred to use

Examples of the sugar alcohol include polyhydric alcohols formed by reducing the aldehyde group of the sugar, that is, erythritol, sorbitol, maltitol, xylitol, mannitol, etc., and the non-saccharide sweetener (diterpene derivative) Examples of the saccharide) include stevioside, aspartame, glycyrrhizin and the like.

The method for producing a beverage according to the present invention is characterized in that the extracted coffee, tea liquor and the like contain a milk raw material and a non-fat milk solid content in which the ratio of the lower middle fatty acid to the fat or the lower middle fatty acid in the lipid is lower than that of milk. And as an alternative to milk. The conditions for extracting coffee or tea liquor can be carried out by a conventional general method, and there are no particular restrictions on coffee beans, tea leaves, roasting conditions, extraction conditions, and the like. Further, at the same time as mixing these milk substitutes, raw materials used in the production of canned coffee and canned tea, such as sweeteners, emulsifiers and baking soda, can be added. The milk-flavored beverage preparation obtained by the above method is homogenized, filled into a container such as a can, sealed, and heat-sterilized to obtain a product.
