Description

  The present invention relates to a container-filled miso soup beverage obtained by filling a container with miso soup as a beverage.

  Miso soup is an indispensable dish on the Japanese table. Generally, miso soup is prepared by adding ingredients to dashi stock and melting miso. However, due to changes in lifestyle, more and more Japanese people want to eat miso soup easily, and instant miso soup that can be easily made has become established in the market. Instant miso soup is a powder type in which miso dried to 5% or less by freeze-drying and natural seasonings, chemical seasonings, etc. are mixed, and ingredients such as leeks that have been freeze-dried or hot-air dried are added. , Add water to normal miso and adjust it to about 55-70% by mass, mix this with natural product seasonings or chemical seasonings, and depending on the product, further knead ingredients A heat-sterilized raw miso type has been established in the market. However, all of the instant miso soups needed to be poured with hot water and stirred, which still took time.

  For this reason, a container-packed miso soup beverage in which miso soup in which miso is dissolved in dashi soup is put in a container, deaerated and sealed, and heat-sterilized has been proposed (Patent Document 1). When manufacturing such a container-packed miso soup beverage, it is necessary to heat sterilize the beverage under the conditions defined in the Food Sanitation Law. However, due to such heat sterilization treatment, sugars and amino acids contained in miso cause a browning phenomenon due to Maillard reaction. Furthermore, since the container-packed miso soup beverage is generally sold warm, the browning has further progressed, and the color and taste are far from the original miso soup, and the commercial value is low.

  Thus, as a measure for improving the color tone, a miso soup-flavored beverage that does not turn brown even when subjected to heat sterilization is proposed by using a non-cooked soybean fermented product instead of miso (Patent Document 2). However, since the miso soup flavored beverage does not use miso, the taste does not reach the original miso soup.

  According to the present invention, it is possible to provide a container-packed miso soup beverage that is good in color tone and taste even after heat sterilization treatment and has little change in color tone and taste even after heating for a long time.

Hereinafter, embodiments of the present invention will be described.
The container-packed miso soup beverage according to the present embodiment is obtained by filtering the miso soup subjected to heat sterilization with 20 mesh (a sieve having an opening of about 850 μm on one side) and satisfying the following conditions (1) to (3): It is.
(1) L value in the Lab color system is 45 to 54
(2) The amount of centrifugal precipitation is 6 to 15% by volume.
(3) The amount of citric acid contained in 100 g of the filtrate is 15 to 60 mg.

(1) L value The L value is an indicator of lightness in the Lab color system, indicating that the larger the L value is, the brighter the light is, and the shorter fermentation is used. The L value of the filtrate of the miso soup after the said process is 45-54, Preferably it is 46-52. When the L value of the miso soup filtrate is in the above range, the miso soup has a bright yellow color as the color tone of the original miso soup and gives a good impression in appearance. If the L value is less than 45, it is too brown and has a low commercial value. On the other hand, when the L value exceeds 54, it becomes a white color that does not look like the original miso soup, and the commercial value is low. The L value can be measured according to a conventional method using a color difference meter, a colorimeter or the like, but the L value of the filtrate in this specification is a spectroscopic color difference meter (SE-2000, Nippon Denshoku Industries Co., Ltd.). To obtain the value obtained by measuring the surface color.

(2) Centrifugal precipitation amount Centrifugal precipitation amount is an index of the taste of miso soup, throat, and ease of drinking. The amount of centrifugal precipitation of the miso soup filtrate after the treatment is 6 to 15% by volume, preferably 8 to 12% by volume. When the amount of centrifugal precipitation is in the above-mentioned range, the miso soup exhibits the touch of the original miso soup, the throat, and the ease of drinking, and is preferable as miso soup. When the amount of centrifugal precipitation is less than 6% by volume, it is thin and uncomfortable when drunk, making it feel unsatisfactory. When the amount of centrifugal precipitation exceeds 15% by volume, it becomes difficult to drink as a beverage. The amount of centrifugal precipitation of the filtrate can be calculated by centrifuging the filtrate at a centrifugal acceleration of 1500 to 2000 G using a centrifuge and measuring the volume of the resulting precipitate.

(3) Amount of citric acid In the present specification, the amount of citric acid represents the mass of citric acid contained in 100 g of the miso soup filtrate after the treatment. Citric acid contained in miso gradually decreases from before fermentation as fermentation progresses. Therefore, the amount of citric acid is an index for measuring the degree of fermentation of miso used in miso soup. The amount of citric acid in the miso soup filtrate after the treatment is 15 to 60 mg, preferably 20 to 40 mg. The amount of citric acid within the above range indicates that miso soup with a short fermentation period is used in a certain amount or more in the miso soup, and a container-filled miso soup beverage with little change in color and taste even after warming for a long time. Obtainable. The method for quantifying the amount of citric acid contained in the filtrate is not particularly limited, and examples thereof include high performance liquid chromatography (HPLC method), ion chromatography, capillary electrophoresis, and the like, and these may be appropriately selected.

The heat sterilization treatment is usually performed under the sterilization conditions defined in the Food Sanitation Law. Specifically, after filling and sealing miso soup in a container such as a metal can, for example, at 120 to 128 ° C. for 10 to 30 minutes (further pressurized to 0.10 to 0.16 MPa as necessary), Heat treatment is performed. Moreover, before filling miso soup into containers, such as a PET bottle, heat processing are performed at 120-150 degreeC for 1 to several tens second using a plate-type heat exchanger etc., for example. The heat treatment conditions are preferably set so that the F ₀ value is 20 or more in order to sufficiently sterilize miso soup. Here, the F ₀ value is a value for evaluating the heat sterilization effect, and corresponds to the heating time (minute) when normalized to the reference temperature (121.1 ° C.).

  In order to produce a container-packed miso soup beverage according to this embodiment, miso soup obtained by dissolving or dispersing miso and seasonings in water may be filled into the container, and heat sterilization treatment before or after filling into the container Attached.

  Miso is a fermented food made mainly from soybeans and fermented with rice, wheat, salt, water, and the like. The main method for producing miso is to cook soybeans, soybeans, and grains such as rice, wheat, etc., add rice, wheat and other grains cooked with koji mold, and then add salt and water. Mixed, fermented and matured (rice miso, barley miso, etc.), soy bean boiled and cultivated with koji mold, or steamed rice, wheat, etc. And a method of mixing and aging water (bean miso etc.). The miso used in the miso soup in this embodiment may be a miso obtained by any of the above production methods.

  As the miso, it is preferable to use one kind or two or more kinds of miso selected from the group consisting of ultra-fine fermented miso, finely fermented miso, weakly fermented miso and weakly fermented miso. It is preferable to use a slightly fermented miso. Here, in this specification, the ultra-micro fermented miso refers to a miso having a fermentation period of 1 to 5 days, the micro-fermented miso refers to a miso having a fermentation period of 6 to 25 days, and a weakly fermented miso has a fermentation period. A 26-39 day miso is said to be a weakly fermented miso, which means a 40-79 day miso fermentation period. That is, as the miso, it is preferable to use a miso having a fermentation period of 1 to 79 days, and it is particularly preferable to use a miso having a fermentation period of 1 to 25 days. Such miso is one that has hardly been eaten as lacking the taste and flavor as miso, but in this embodiment, by using the miso, browning is suppressed even if heat sterilization treatment is performed, A container-filled miso soup beverage can be obtained which is preferable in both color tone and taste and has little change in color tone and taste even after being heated for a long time. In addition, in this specification, in addition to the above-mentioned miso, the terms medium fermented miso (fermentation period 80 to 100 days) and strong fermented miso (fermentation period 101 days or more) may be used.

  The amount of miso used in the miso soup of the present embodiment is preferably 5 to 12% by mass and particularly preferably 6 to 10% by mass in the miso soup. When the amount of miso used is within the above range, a container-filled miso soup beverage with good taste and color can be obtained.

  Examples of water used in the miso soup of this embodiment include water suitable for drinking, such as pure water, hard water, soft water, ion-exchanged water and the like, and deaerated water obtained by degassing these waters. Among these waters, it is preferable to use deaerated water. By using deaerated water, deterioration of the container-packed miso soup beverage due to oxidation can be prevented, and the drinking period can be extended.

  The miso soup in the present embodiment usually contains a seasoning. In addition, the seasoning in this specification shall also include dashi.

  The seasonings are not particularly limited, but natural seasonings prepared from bonito, kelp, shiitake, scallops, dried sardines, etc. or extracts thereof; sodium glutamate, sodium inosinate, sodium guanylate, sodium succinate, etc. Umami seasonings; inorganic salts such as salt, bittern, potassium chloride and magnesium chloride.

  Although the content of the seasoning in the miso soup of the present embodiment is not particularly limited as long as it does not impair the taste as a container-filled miso soup, it is usually preferably 0.5 to 3% by mass in the miso soup.

  The miso soup in the present embodiment preferably contains ingredients. By containing ingredients, it is possible to provide a container-filled miso soup beverage that is more tasteful and highly satisfactory.

  Examples of the ingredients include green onions, spinach, radish vegetables, Nozawana, mizuna, cabbage, lettuce and other leafy vegetables; okra, pumpkin and other fruit vegetables; onion, radish, turnip, carrot, burdock, potato, taro, sweet potato Root vegetables such as sea cucumbers, mushrooms such as sea cucumbers, shiitake mushrooms, shimeji mushrooms; seaweeds such as sea breams, seaweeds and swordfish; Various foods such as processed foods can be used.

  Among the above ingredients, it is preferable to use a plant containing chlorophyll or a processed product of the plant. As plants containing chlorophyll, leafy vegetables, fruit vegetables and seaweeds are preferred. By using a plant containing chlorophyll or a processed product of the plant, it is possible to visually suppress the color change of the container-packed miso soup beverage due to the heat sterilization treatment.

  The content of ingredients in the miso soup of this embodiment is usually 10% by mass or less, preferably 5% by mass or less. When there are more ingredients than 10% by mass, it tends to be difficult to drink as a beverage. Moreover, when it contains the plant containing chlorophyll as an ingredient, it is preferable that the content is 0.1 mass% or more, and it is especially preferable that it is 0.3 mass% or more. When the content of the plant containing chlorophyll is 0.1% by mass or more, the color tone change of the container-packed miso soup beverage due to the heat sterilization treatment can be visually suppressed.

  The miso soup in the present embodiment preferably contains a paste (including a stabilizer and a thickener) in order to improve the dispersibility or stability in water of insoluble solid components such as miso components. In miso soup, the miso component precipitates over time, so the supernatant becomes transparent, but by containing a paste, the miso component does not easily precipitate over time and the miso soup is maintained in a homogeneous state. be able to.

  Examples of the paste include cellulose such as crystalline cellulose and microfibrous cellulose, pectin, gelatin, collagen, agar, carrageenan, sodium alginate, soybean polysaccharide, gum arabic, guar gum, xanthan gum, tamarind seed gum, gellan gum and the like. However, cellulose is preferable from the viewpoint of pH and viscosity, and crystalline cellulose is particularly preferable.

  The content of the paste in the miso soup of the present embodiment is preferably 0.1 to 0.4% by mass, and particularly preferably 0.15 to 0.25% by mass in the miso soup. When the content of the paste is 0.1% by mass or more, the above precipitation preventing effect is sufficiently obtained. On the other hand, when the content of the paste is more than 0.4% by mass, the viscosity of miso soup becomes high, which may make it unsuitable as a beverage.

  In addition to the above, the miso soup in the present embodiment may be blended with various additives generally used in the production of miso soup as needed. Such additives are not particularly limited, and for example, antioxidants, fragrances, various esters, organic acids, organic acid salts, inorganic acids, inorganic acid salts, inorganic salts, pigments, preservatives. , Seasonings, pH adjusters, quality stabilizers and the like.

  The container-packed miso soup drinks obtained in Examples 1 to 5 and Comparative Examples 1 to 5 were evaluated by the following tests.

[Test Example 1] (Lightness measurement test)
The container-packed miso soup drinks obtained in Examples 1 to 5 and Comparative Examples 1 to 5 were cooled to about 40 ° C. and then opened, and the miso soup was filtered through a 20 mesh screen to obtain a filtrate. The surface color of the obtained filtrate was analyzed with a spectroscopic color difference meter (SE-2000, manufactured by Nippon Denshoku Industries Co., Ltd.), and the L value, which is an index representing lightness, was measured. The results are shown in Table 2.

[Test Example 2] (Quantitative sedimentation test for centrifugal sedimentation)
10 g of the filtrate obtained in the same manner as in Test Example 1 was put into a 10 mL centrifuge sedimentation tube with a scale, and a centrifuge LC06-SP (Tomy Seiko Co., Ltd.) and a rotor TS-7 (Tomy Seiko Co., Ltd.) were used. And centrifuged at 3000 rpm (centrifugal acceleration 1750G) for 10 minutes. The volume of the obtained precipitate was measured by reading from the scale of the centrifugal sedimentation tube, and the centrifugal sedimentation amount (volume%) with respect to the filtrate was calculated. The results are shown in Table 2.

[Test Example 3] (Quantitative test of citric acid)
Water was added to 5 g of the filtrate obtained in the same manner as in Test Example 1 to make 25 mL. The solution was filtered through a filter (0.45 μm, Millex-HP Hydorphilic PES, manufactured by Millipore) to remove insoluble matters, and then analyzed by high performance liquid chromatography under the following conditions. The amount of citric acid was calculated from the area of the peak with the same retention time. The results are shown in Table 2.

Stationary phase: ODS column Column diameter: 4.6 mm
Column length: 250mm
Mobile phase flow rate: 0.6 mL / min
Mobile phase: 50 mM ammonium phosphate aqueous solution Detection wavelength: 210 nm

[Test Example 4] (Color tone evaluation test)
The container-packed miso soup drinks obtained in Examples 1 to 5 and Comparative Examples 1 to 5 were cooled to about 40 ° C. and then opened to evaluate the color tone of miso soup (red tint of miso soup). Such a color tone evaluation test was conducted by visually observing the miso soup by five trained panelists in charge of beverage development and evaluating the miso soup in five stages according to the following criteria. Table 2 shows the result of rounding off the average score of the obtained evaluations to the first decimal place.

= Evaluation of red coloration of miso soup =
5: There is no redness.
4: A little reddish.
3: There is redness.
2: A little reddish.
1: Strong redness.

[Test Example 5] (Sensory evaluation test)
The container-packed miso soup beverages obtained in Examples 1 to 5 and Comparative Examples 1 to 5 were cooled to about 40 ° C., and then opened, and the taste of the miso soup was subjected to sensory evaluation. The sensory evaluation test was conducted by tasting the miso soup with five trained panelists in charge of beverage development. The taste was evaluated according to the following criteria in five stages. Table 2 shows the result of rounding off the average score of the obtained evaluations to the first decimal place.

= Evaluation of the balance of umami, sour and salty taste =
5: Very good.
4: Good.
3: Neither.
2: Bad.
1: Very bad.

= Evaluation of bitterness =
5: There is no bitterness.
4: There is a little bitterness.
3: There is a bitter taste.
2: Bitterness is a little strong.
1: The bitterness is very strong.

  Further, based on the results of the color tone evaluation test and the sensory evaluation test, comprehensive evaluation was performed according to the following criteria. The results are shown in Table 2.

= Comprehensive evaluation =
○: Red coloration of miso soup and evaluation of the balance of umami, sourness, salty taste are 3 points or more and evaluation of bitterness is 4 points or more ×: Redness coloring of miso soup or evaluation of balance of umami, sourness, salty taste is 2 Less than 3 points or less than 3 points

  In Examples 1 to 5, there was no problem in the color tone (reddish coloring), and the balance of taste and evaluation of bitterness were high. In contrast, Comparative Examples 1 to 5 had a low evaluation of taste balance. In Comparative Example 3, the amount of centrifugal precipitation was large, and the evaluation of bitterness was low. Further, Comparative Examples 4 and 5 had a low evaluation of color tone (reddish coloring) and a low evaluation of bitterness.

  Moreover, after heating the container-packed miso soup drink of Examples 1-5 and Comparative Examples 1-5 at 60 degreeC for 7 days, it opened it. As a result, the miso soups of Examples 1 to 5 had a bright color tone, good taste balance and no bitterness even after being placed under heating conditions for 7 days, and therefore the evaluation of the color tone and taste was high.
