  ADVANTAGE OF THE INVENTION According to this invention, the tomato fruit juice containing drink which is easy to drink clearly and can also feel the original taste of tomato can be provided.

Hereinafter, one embodiment of the present invention will be described in detail.
This embodiment relates to a tomato fruit juice-containing beverage. The tomato juice-containing beverage of this embodiment contains tomato juice and alanine. Moreover, the tomato juice rate in the tomato juice-containing beverage is 40 to 99%, the proportion of alanine is 2 to 7 mass% with respect to the whole tomato juice-containing beverage, and the acidity is 1.0% or less.

In the present specification, the tomato juice-containing beverage means a beverage containing tomato juice as a raw material.
In this specification, tomato fruit juice refers to a liquid component obtained by crushing tomato and squeezing or squeezing it. In addition, the tomato juice of the present specification is a concept that includes the concentrated liquid component and diluted reduced products thereof. Furthermore, the tomato juice according to the present embodiment may be one containing a pulp content or one obtained by removing the pulp content by a process such as filtration or centrifugation.
Specific examples of tomato juice include tomato juice, tomato puree, tomato paste, and concentrated tomato specified by JAS standards. For example, one or more of these contain the tomato juice of this embodiment. Can be used for beverage preparation.

  The variety, production area, maturity, size, and the like of tomatoes that can be used for the preparation of tomato juice according to the present embodiment are not particularly limited, and can be set as appropriate. Moreover, you may make it prepare the tomato fruit juice containing drink of this embodiment using commercially available tomato juice, tomato paste, etc. as tomato fruit juice.

The tomato juice rate in the tomato juice-containing beverage of this embodiment is 40 to 99%, preferably 50 to 99%. Here, the fruit juice rate is a relative concentration when the Brix value of tomato juice (straight fruit juice) obtained by squeezing tomato and not subjected to treatment such as concentration is 100%. For example, when producing a tomato juice-containing beverage having a tomato juice ratio of 65%, a tomato paste having a Brix value of 29.3 and a Brix value of 4.5 at the time of squeezing is 10% by mass in the whole tomato juice-containing beverage. What is necessary is just to mix | blend.
In this specification, the Brix value refers to the reading of a refractometer for sugar at a sample temperature (liquid temperature) of 20 ° C. The Brix value can be measured using a known method and apparatus.

  When the tomato juice content in a tomato juice-containing beverage is less than 40%, it becomes harder to feel the tomato's original taste than when it is within the range when drinking, and compared to when it is within the range You will not feel delicious. Moreover, when the value of tomato fruit juice ratio is larger than 99%, a residual feeling is felt after drinking as compared with the case where it is within the range.

The tomato juice-containing beverage of this embodiment contains alanine in addition to tomato juice. Alanine is one of the neutral amino acids that make up protein. Alanine is widely present in nature, and is abundant in, for example, seafood. In addition, alanine is a substance specified by the Minister of Health, Labor and Welfare based on the provisions of Article 11, Paragraph 3 of the Food Sanitation Law (Act No. 233 of 1947) that it is clear that there is no risk of harming human health. is there. Therefore, alanine is widely used as a food additive. The alanine that may be contained in the tomato juice-containing beverage of this embodiment may be, for example, commercially available, and may be racemic, D-form, or L-form.
Moreover, in the tomato fruit juice containing drink of this embodiment, alanine can be made into the aspect containing both what originated in tomato, and what was added. However, the ratio of alanine according to the present embodiment may be calculated from only the amount of alanine derived from tomato that is added and contained in the beverage because the amount of alanine derived from tomato is very small.

In this embodiment, alanine can be contained at a ratio of 3 to 7% by mass with respect to the whole tomato juice-containing beverage of this embodiment. When the content ratio of alanine is less than 3% by mass, the taste, the original taste of tomato, and the ease of drinking are not sufficient compared to the range. In addition, when the content of alanine is larger than 7% by mass, it does not feel delicious compared to the range or does not feel the original taste of tomato.
In addition, what is necessary is just to use a well-known method for content measurement of alanine, For example, content of alanine in a tomato fruit juice containing drink can be calculated | required by the high performance liquid chromatogram method (HPLC amino acid analysis system (made by Shimadzu Corporation)). .

In addition, the tomato juice-containing beverage of this embodiment has an acidity of 1.0% or less, preferably 0.2 to 1.0%. More preferably, it is 0.4 to 0.8%, and still more preferably 0.65 to 0.8%.
In the present specification, the acidity means the acid concentration (%) in terms of citric acid calculated by potentiometric titration using a 0.1 mol / L sodium hydroxide standard solution.
The acidity is titrated with sodium hydroxide using a phenolphthalein indicator, and can be calculated as follows with the equivalent amount of citric acid.
First, accurately weigh 5 to 15 g of sample into a 200 ml Erlenmeyer flask, dilute with water appropriately, add a few drops of 1% phenolphthalein indicator, and titrate while shaking with 0.1 M sodium hydroxide in a 25 ml burette. To do. The end point is the point where the red color lasts for 30 seconds. When using a hydrogen ion concentration meter, titrate in the same manner while stirring with a magnetic stirrer, and the end point is when the pH is 8.1.
The acidity can be calculated by the following formula (1).

DA = A × f × 100 / W × 0.0064 (1)

  In formula (1), DA is the acidity (%), A is the titration with 0.1M sodium hydroxide solution (ml), f is the titer of 0.1M sodium hydroxide solution, W is the sample mass (g) Means. 0.0064 is the mass (g) of anhydrous citric acid corresponding to 1 ml of 0.1M sodium hydroxide solution.

When the acidity value is larger than 1.0%, the acidity is too strong compared to the case where the acidity value is within the range, so that it is not suitable for drinking.
In this embodiment, the acidity of the tomato juice-containing beverage can be adjusted by, for example, adding a sour agent in the beverage or adjusting the blending ratio of tomato juice.

When using an acidulant as an additive, the kind and amount thereof are not particularly limited as long as the acidity in the tomato juice-containing beverage can be adjusted within a range of 1.0% or less. Examples of acidulants include organic acids such as citric acid, lactic acid, acetic acid, malic acid and salts thereof, inorganic acids such as phosphoric acid and salts thereof, and fruit juices such as lemon juice. For example, one or two of them The above may be blended in the tomato juice-containing beverage.
Among these, it is preferable that the tomato fruit juice containing drink of this embodiment further contains a citric acid and / or lemon fruit juice from a viewpoint of the end of the taste of a tomato fruit juice containing drink.

  In the tomato juice-containing beverage of this embodiment, in addition to the tomato juice and alanine, other components may be included as long as the effects of the present invention are not impaired. Specifically, in addition to the above-mentioned acidulants, solids such as fruit juices of other vegetables and fruits, pulp components, salt, saccharides, fragrances, vitamins, pigments, coloring agents, antioxidants, sweeteners, emulsifiers, storage Ingredients that are usually blended in beverages, such as flavorings, seasonings, extracts, pH adjusters, and quality stabilizers, can be blended.

  Moreover, the tomato fruit juice containing drink of this embodiment may be a drink classified into any kind, and is not specifically limited. For example, the tomato juice-containing beverage of the present embodiment can be a beverage classified as a tomato juice drink or a tomato mix juice based on a tomato processed product quality display standard. Moreover, alcohol may be added and prepared as an alcoholic beverage. Furthermore, it may be anything that has fluidity at the time of drinking, including those that are frozen and solid at the time of sale, and those that are chewable when drinking, such as jelly drinks.

The tomato juice-containing beverage of the present embodiment can be produced, for example, according to a conventional method, and as long as the fruit juice ratio of tomatoes, the content ratio of alanine and the acidity satisfy the above range in the resulting beverage, The ratio and manufacturing conditions are not particularly limited.
For example, while diluting tomato paste with water in a range where the tomato juice ratio after beverage production is 44 to 99%, alanine or beverage production in which the ratio after beverage production is 3 to 7% by mass in the diluted solution The tomato juice-containing beverage of the present embodiment can be prepared by adding citric acid or the like in such an amount that the subsequent acidity is 1.0% or less.
