Description

Liquid seasoning and method for producing same
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
Conventionally, sesame-flavored liquid seasonings 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 liquid with sesame powder, cooked sesame powder, and the like, and are seasonings having sesame-specific aroma. In addition to salad dressing, the use of such sesame-flavored liquid seasonings has been used as a sauce for tofu, meat, and the like, and in recent years, the use frequency on dining tables has tended to increase.
In liquid seasonings containing sesame, the unique flavor of sesame is easily deteriorated, so various studies have been made to maintain the unique flavor of sesame. For example, it has been proposed to blend a specific aroma component (2-propionylthiazole) into a liquid seasoning containing sesame seeds in order to maintain the light aroma of the freshly ground sesame seeds after baking for a long period of time (for example, see patent literature 1). In addition to enhancing the unique fragrance of sesame, it has been proposed to adjust the ratio of specific aroma components (linear alkanethiols and dimethylpyrazines) in a liquid seasoning containing sesame in order to enhance the unique fragrance that is addictive to humans (for example, refer to patent document 2).

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. Depending on the type of liquid seasoning, the seasoning may further contain acidic substances such as water and acetic acid, seasonings such as soy sauce, granulated sugar and miso, emulsifying agents, and other raw materials.
The liquid seasoning is preferably emulsified. The emulsified liquid seasoning may have a composition of an oil-in-water type (O/W type) emulsion or a W/O/W type composite emulsion, and more preferably an oil-in-water type (O/W type) emulsion.
Examples of the liquid seasoning include sauce, and other foods similar to these, and sauce is preferable.
(aroma component)
The liquid seasoning contains at least p-cymene and 2, 6-dimethylpyrazine as aroma components, and has unique fragrance of sesame and fresh citrus aroma. The liquid seasoning may contain, in addition to p-cymene and 2, 6-dimethylpyrazine, a fragrance component contained in a usual sesame-containing liquid seasoning, and may further contain other fragrance components within a range that does not impair the effects of the present invention.
In the liquid seasoning, when the aroma component is measured by the solid-phase microextraction-gas chromatography mass spectrometry method described in detail below, the ratio of the peak area of cymene to the peak area of 2, 6-dimethylpyrazine (the peak area of cymene/the peak area of 2, 6-dimethylpyrazine) is 11 or more and 250 or less, the lower limit is preferably 13 or more, more preferably 18 or more, further preferably 19 or more, further preferably 20 or more, and the upper limit is preferably 215 or less, more preferably 200 or less, further preferably 175 or less, further more preferably 150 or less. When the ratio of the peak area of cymene to the peak area of 2, 6-dimethylpyrazine is within the above-mentioned numerical range, the citrus fruit peel has a unique fragrance of sesame, and is bitter and fresh in citrus aroma.
The content of cymene in the liquid seasoning is, for example, 0.5ppm or more and 20.0ppm or less, the lower limit is preferably 0.8ppm or more, more preferably 1.1ppm or more, further preferably 1.4ppm or more, and the upper limit is preferably 17.0ppm or less, more preferably 15.0ppm or less, further preferably 13.0ppm or less. When the content of p-cymene in the liquid seasoning is within the above-mentioned numerical range, the liquid seasoning has a unique fragrance of sesame, has the original bitter taste of citrus peel, and gives a more intense sensation of fresh citrus aroma. The content of p-cymene in the liquid seasoning can be measured and calculated by a conventional method using a gas chromatograph, and can be measured by, for example, solid phase microextraction-gas chromatography mass spectrometry (SPME-GC-MS).
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 examples thereof include adding p-cymene and 2, 6-dimethylpyrazine to the liquid seasoning, respectively, as a perfume. Alternatively, a method of blending a food or food additive containing p-cymene and 2, 6-dimethylpyrazine may be mentioned. Specifically, there may be mentioned an extract containing p-cymene obtained by adjusting the content of the p-cymene-containing citrus peel in a liquid seasoning or adding p-cymene-containing extract obtained by extracting citrus peel to a liquid seasoning. Further, there may be mentioned an extract containing 2, 6-dimethylpyrazine obtained by adjusting the content of sesame containing 2, 6-dimethylpyrazine in a liquid seasoning, or by adding sesame subjected to a treatment such as baking to a raw material sesame to a liquid seasoning and extracting the sesame.
Even if the amounts of p-cymene and 2, 6-dimethylpyrazine in the liquid seasoning are the same, the peak areas obtained are different from each other in the characteristics of the solid-phase microextraction-gas chromatography-mass spectrometry method. Examples of the reasons for this include different amounts of components volatilized into the gas phase due to different volatilities of 2 components, different affinities of components in other samples, and the like. From various factors due to the characteristics of the measurement method, the ratio calculated from the peak area and the ratio calculated from the quantitative value are different in numerical value.
