Technical Field

The present invention relates to a liquid seasoning, and more particularly, to a liquid seasoning containing sesame, citrus peel, and edible oil. The present invention also relates to a method for producing the liquid seasoning.

Background

Liquid seasonings having a sesame flavor such as sesame sauce, sesame mayonnaise, and sesame sauce using sesame as a raw material have been sold. These liquid seasonings are obtained by uniformly mixing a liquid seasoning containing sesame powder, crushed cooked sesame, and the like, and have a flavor specific to sesame. As applications of such sesame-flavored liquid seasonings, in addition to salad dressing, they are used as sauces for tofu, meat and the like, and in recent years, the frequency of use on the table tends to increase.

In sesame-containing liquid seasonings, various studies have been made to maintain the unique aroma of sesame because the unique aroma of sesame is easily deteriorated. For example, it has been proposed to blend a specific aroma component (2-propionylthiazole) in a liquid seasoning containing sesame in order to maintain a light aroma of freshly ground roasted sesame for a long period of time (see, for example, patent document 1). In addition to enhancing the unique aroma of sesame, it has been proposed to adjust the ratio of specific aroma components (linear alkanethiol and dimethylpyrazine) in a liquid seasoning containing sesame in order to enhance the unique aroma of people who become addicted (see, for example, patent document 2).

ADVANTAGEOUS EFFECTS OF INVENTION

According to the present invention, a liquid seasoning containing sesame can be provided which has the fragrance peculiar to sesame, has the original bitterness of citrus peel, and has a clear citrus fragrance. Further, the present invention can provide a method for producing such a liquid seasoning. Such a liquid seasoning can stimulate the appetite of consumers, and further expansion of the market of the liquid seasoning can be expected.

Detailed Description

< liquid seasoning >

The liquid seasoning of the present invention contains at least sesame, citrus peel, and edible oil and fat, and contains the following specific aroma components. Further, depending on the kind of the liquid seasoning, it may contain water, acidic substances such as acetic acid, seasonings such as soy sauce, granulated sugar, miso, emulsifiers, other raw materials, and the like.

The liquid seasoning is preferably in an emulsified form. The emulsified liquid seasoning may have the structure of an oil-in-water (O/W type) emulsion or a W/O/W type composite emulsion, and the structure of an oil-in-water (O/W type) emulsion is more preferable.

Examples of the liquid seasoning include a sauce, and other similar foods, and a sauce is preferable.

(aroma component)

The liquid seasoning contains at least p-cymene and 2, 6-dimethylpyrazine as fragrance components, and has a characteristic fragrance of sesame and a fresh citrus fragrance. The liquid seasoning may contain, in addition to p-cymene and 2, 6-dimethylpyrazine, aroma components contained in a normal liquid seasoning containing sesame, and may further contain other aroma components within a range not impairing the effects of the present invention.

In the liquid seasoning, when the fragrance component is measured by a solid phase microextraction-gas chromatography-mass spectrometry method described in detail below, the ratio of the peak area of p-cymene to the peak area of 2, 6-dimethylpyrazine (peak area of p-cymene/peak area of 2, 6-dimethylpyrazine) is 11 or more and 250 or less, the lower limit value is preferably 13 or more, more preferably 18 or more, further preferably 19 or more, further preferably 20 or more, and the upper limit value is preferably 215 or less, more preferably 200 or less, further preferably 175 or less, further preferably 150 or less. When the ratio of the peak area of p-cymene to the peak area of 2, 6-dimethylpyrazine is within the above numerical range, the citrus fruit can have the fragrance peculiar to sesame, the bitterness inherent to citrus peel, and the fresh citrus fragrance.

The p-cymene content is, for example, 0.5ppm or more and 20.0ppm or less with respect to the total amount of the liquid seasoning, the lower limit is preferably 0.8ppm or more, more preferably 1.1ppm or more, and further preferably 1.4ppm or more, and the upper limit is preferably 17.0ppm or less, more preferably 15.0ppm or less, and further preferably 13.0ppm or less. When the p-cymene content in the liquid seasoning falls within the above numerical range, the liquid seasoning can have the fragrance peculiar to sesame, has the original bitterness of citrus peel, and can further strongly receive a refreshing citrus fragrance. The p-cymene content in the liquid seasoning can be measured and calculated by a conventional method using a gas chromatograph, for example, by a solid phase microextraction-gas chromatography-mass spectrometry (SPME-GC-MS) method.

The method for adjusting the peak areas or the contents of p-cymene and 2, 6-dimethylpyrazine in the liquid seasoning is not particularly limited, and for example, the addition of p-cymene and 2, 6-dimethylpyrazine as perfumes to the liquid seasoning is included. Alternatively, a method of blending a food or a dietary supplement containing p-cymene and 2, 6-dimethylpyrazine is exemplified. Specifically, the content of the citrus peel containing p-cymene in the liquid seasoning is adjusted, or an extract containing p-cymene obtained by extraction from citrus peel is added to the liquid seasoning. Further, the content of sesame containing 2, 6-dimethylpyrazine in the liquid seasoning is adjusted, or an extract containing 2, 6-dimethylpyrazine, which is obtained by extracting sesame, which is obtained by subjecting raw sesame to a treatment such as baking, is added to the liquid seasoning.

It is noted that even when p-cymene and 2, 6-dimethylpyrazine were present in the same amount in the liquid seasoning, the peak areas obtained were different in the characteristics of the solid phase microextraction-gas chromatography-mass spectrometry combination. Examples of the reason for this include that the amount of the component volatilized into the gas phase differs depending on the volatility of 2 components and the difference in affinity with the components in other samples. Further, the ratio calculated from the peak area and the ratio calculated from the quantitative value are numerically different from each other due to various factors caused by the characteristics of the measurement method.
