Description

  The present invention relates to a deacidified tomato juice, a method for producing the same, and a tomato-containing beverage and a method for suppressing acidity of a tomato-containing beverage.

  Tomato juice specified by the JAS standard (tomato crushed and squeezed or strained, skin and seeds removed (hereinafter also referred to as “tomato squeezed”), or salt added thereto, and , The concentrated tomato diluted to the squeezed state or the salt added to it), the original flavor of the tomato has been reproduced, regardless of age or gender, It is loved by people. However, the tomato juice specified by the JAS standard is inherently high in viscosity because it contains a large amount of water-insoluble solids such as dietary fiber, and therefore has the disadvantage of being relatively difficult to drink. The market is gradually shrinking, coupled with changes in consumer preferences.

  On the other hand, various tomato mixed drinks have been developed in which vegetable juice such as fruit juice and carrot juice is blended with tomato juice as a main ingredient. In this type of tomato mix beverage, the viscosity can be lowered by blending fruit juice and vegetable juice, and the sourness of tomato can be concealed by the sweetness of the fruit juice, etc., so the ease of drinking tends to be improved. However, this type of tomato mix beverage is rather close to a fruit juice beverage or a vegetable juice beverage, and therefore lacks appeal to consumers as a tomato beverage.

  On the other hand, in order to improve the ease of drinking without blending fruit juice or vegetable juice, it has been studied to reduce the viscosity of tomato-containing beverages. For example, in Patent Document 1, the viscosity is 250 to 3000 mPa · There is described a method for producing low-viscosity tomato juice, characterized in that plant tissue-disintegrating enzyme is added to raw material tomato juice adjusted to the range of s and treated at a shear rate range of 103 to 1061 / s.

  In addition, addition of various taste improvers for improving the flavor of foods has also been studied. For example, Patent Document 2 discloses a transparent tomato concentration obtained by separating serum from tomato juice and concentrating it. Things are listed.

JP 2009-011287 A JP 2009-232851 A

  In Patent Document 1, it is described that water-insoluble solids are solubilized and viscosity reduction is promoted, and as a result, a tomato juice with improved throat penetration is obtained. However, the method of Patent Document 1 requires a long-time shearing process, and further requires a heat treatment for enzyme deactivation. Along with this, there is a problem that flavor deterioration, heating odor and the like may occur.

  Moreover, although the low-viscosity tomato juice of the above-mentioned Patent Document 1 is described as having improved throat penetration by lowering the viscosity, there is no description about the adjustment of tomato flavor, particularly sweetness and sourness. Like the tomato juice specified by the JAS standard, it is difficult to say that it is easy to drink for those who are not good at the sour taste of tomato.

  On the other hand, Patent Document 2 describes that the taste of food is improved due to various amino acids present in the transparent tomato concentrate. However, the transparent tomato concentrate described in the above-mentioned Patent Document 2 has sufficient tomato acidity, and therefore it is used to realize a tomato-containing beverage that is easy to drink for those who are not good at acidity of tomato. Was difficult.

  The present invention has been made in view of such circumstances, and its purpose is to provide a novel tomato-containing beverage with a rich taste, sweetness like fruit tomatoes, and a reduced tomato acidity with good reproducibility. Feasible novel deacidified tomato juice and method for producing the same, and a novel tomato-containing beverage and a tomato-containing beverage that have a sweet taste like a fruit tomato with a rich taste and the sourness of the tomato is suppressed It is to provide a method.

  As a result of intensive research, the inventors have passed transparent tomato juice through bicarbonate-substituted or carbonate-substituted anion exchange resin, and by using this as a raw material for tomato-containing beverages, The present inventors have found that the above problems can be solved and have completed the present invention.

That is, the present invention provides the following (1) to (5).
(1) It is obtained by passing transparent tomato juice through a bicarbonate-substituted or carbonate-substituted anion exchange resin.
Deacidified tomato juice.

(2) The transparent tomato juice is passed in an upward flow manner,

Tomato-containing beverage.

(5) The deoxidized tomato juice according to any one of the above (1) to (3) is blended with the tomato juice or the concentrate thereof,
A method for suppressing acidity of tomato-containing beverages.

  According to the present invention, a novel deacidified tomato juice and its production capable of easily and reproducibly producing a novel tomato-containing beverage that has a rich taste, has a sweet taste like fruit tomatoes, and the sourness of tomatoes is suppressed. The method was realized, and by using this, there was a sweet taste like a fruit tomato with a rich taste, and the acidity of the tomato was suppressed, without blending vegetable juice and fruit juice other than tomato as the main ingredient, A novel tomato-containing beverage and its production method can be easily realized with good reproducibility. Moreover, according to the other aspect of this invention, the acidity of a tomato containing drink is suppressed effectively.

  And according to the aspect of the tomato-containing beverage that does not substantially contain vegetable juice and / or fruit juice other than tomato among the present invention, the conventional tomato beverage that is highly viscous and difficult to drink, the conventional tomato that is sour and difficult to drink Tomato-containing beverages different from any of the above-mentioned conventional tomato mix beverages close to beverages, fruit juice beverages or vegetable juice beverages, and tomato beverages described in Patent Document 1 having low viscosity and strong acidity, that is, tomato originally with a rich taste As a new market category of pure tomato-containing beverages that can be drunk deliciously as a beverage form is created, it is possible to follow the diversification of consumer preferences in recent years .

  Embodiments of the present invention will be described below. In addition, the following embodiment is an illustration for demonstrating this invention, and this invention is not limited only to the embodiment.

  The deacidified tomato juice of this embodiment contains tomato fruit-derived material as a main raw material, and is obtained by passing transparent tomato juice through a bicarbonate-substituted or carbonate-substituted anion exchange resin. It is.

  Here, in this specification, the tomato fruit-derived material refers to a tomato juice obtained by crushing and squeezing or squeezing the tomato and removing the skin, seeds, etc., and those concentrated (concentrated) Tomato) (including those obtained by diluting and reducing these), and is a concept that includes tomato juice, tomato puree, tomato paste, concentrated tomato and the like specified by the JAS standard. These may further contain other components (for example, a small amount of salt, spices, food additives, etc.). The property of the tomato fruit-derived material is not particularly limited, and may be any of liquid, gel, paste (pseudo-solid), semi-solid, and solid. In addition, a main raw material means what occupies 50 weight% or more with respect to the total amount of a tomato containing drink.

  Moreover, in this specification, transparent tomato juice means that T% (transmittance at 660 nm) which is an index of turbidity is 10% or more. As such transparent tomato juice, a concentrated supernatant obtained by centrifuging the above-described tomato juice or concentrated tomato (in other words, a part of the water-insoluble solid contained in the tomato juice or concentrated tomato Removed concentrated tomato) and those obtained by diluting and reducing them. Further, “transparent” means that, in Brix 4.5, the transparency exceeds that of Brix 4.5. In addition, transparent tomato juice can be used by concentrating or diluting as necessary, and is not particularly limited. However, from the viewpoint of ease of handling during beverage production, the transparent tomato juice has a salt-free soluble solid content of 4 to 70%. preferable.

  Preparation of said transparent tomato juice can be suitably performed by a well-known method in this industry, and is not specifically limited. For example, according to a conventional method, it can be obtained by concentrating the supernatant obtained by centrifuging the above-described tomato juice or concentrated tomato, and also concentrating commercially available tomato juice or concentrated tomato In addition, a commercially available transparent tomato juice can also be used. Although it does not specifically limit as a transparent tomato juice of a commercial item, For example, the clear tomato concentrate of San-Ei Gen FFI etc. are mentioned. In addition, transparent tomato juice (B) can be used individually by 1 type or in combination of 2 or more types.

  In addition, as a squeezing method in the above, a method of squeezing using a reamer or the like, a method of squeezing and squeezing using a hydraulic press machine, a roller squeezing machine or an inline squeezing machine, crushing and squeezing using a pulper finisher or the like There is known a method of juice, and a method of crushing using a crusher or the like, heating with a tube heater or the like to sterilize and deactivate the enzyme, and then squeezing using an extractor or the like. Furthermore, what was squeezed (squeezed) according to these methods may be applied to a juicer and / or sterilized as desired. Furthermore, what was squeezed (squeezed) according to these methods may be subjected to an enzyme treatment such as pectinase or cellulase, a juicer, or sterilized, if desired. Further, as the above-described concentration method, for example, normal heating concentration, reduced pressure concentration, low temperature concentration, vacuum concentration, freeze concentration, reverse osmosis concentration, and the like are known.

  By passing the above transparent tomato juice through a bicarbonate-substituted or carbonate-substituted anion exchange resin, the sourness of the treated transparent tomato juice (deacidified tomato juice) is reduced. It is presumed that this is due to removal of sour components such as citric acid contained in the transparent tomato juice by placing the bicarbonate, and the substituted bicarbonate is discharged as carbon dioxide.

  Here, the transparent tomato juice used as a raw material for the deacidified tomato juice of the present embodiment can be used by concentrating or diluting as necessary, and is not particularly limited, but from the viewpoint of obtaining a deacidified tomato juice having a high sugar content. , Brix is preferably 8-80. In addition, in this specification, sugar content means a Brix value. Here, the Brix value is a unit for measuring the gram amount of soluble solids (such as sugars) contained in 100 g of a solution. The Brix value can be measured using a commercially available refractometer or saccharimeter.

  Moreover, although the transparent tomato juice used as a raw material of the deoxidized tomato juice of this embodiment is not specifically limited, It is preferable that the acidity at the time of Brix4.5 adjustment is 0.1-0.5. There exists a tendency for the acidity of the deoxidized tomato juice obtained by using transparent tomato juice with low acidity to become low. On the other hand, the higher the acidity of the transparent tomato juice, the more easily the effect of reducing the acidity due to the blending of calcium or a salt thereof tends to be exhibited. In the present specification, the acidity means a concentration (%) in terms of citric acid calculated by a potentiometric titration method using a 0.1 mol / L sodium hydroxide standard solution.

  Moreover, although the transparent tomato juice used as a raw material of the deoxidized tomato juice of this embodiment is not specifically limited, It is preferable that pH is 3.7-4.6. When the pH is biased to the neutral side, the effect of the calcium or salt combination tends to be low, and the citric acid reduction rate of the resulting deacidified tomato juice tends to be low.

  The bicarbonate-substituted or carbonate-substituted anion exchange resin used for treating transparent tomato juice is required to be an anion exchange resin in which bicarbonate ions or carbonate ions are ion-bonded. The anion exchange resin as the base material is preferably a strong basic ion exchange resin or a weak basic ion exchange resin. By replacing the ion exchange group such as Cl ion or hydroxyl group contained in the strong basic ion exchange resin or weak basic ion exchange resin with bicarbonate ion or carbonate ion, the bicarbonate substitution or carbonate substitution was performed. An anion exchange resin can be easily obtained.

  The method for passing the transparent tomato juice is not particularly limited and may be either an upward flow method or a downward flow method, but the upward flow method is preferable from the viewpoint of productivity. Carbon dioxide gas can be generated with the replacement with bicarbonate ion or carbonate ion, but if the upward flow method is adopted, the carbon dioxide gas is likely to escape along the liquid passing direction, so that it is disposed in or in the anion exchange resin. A decrease in productivity due to the stay of carbon dioxide in the column can be suppressed.

  The deacidified tomato juice thus obtained is removed by removing at least a part of unnecessary water-insoluble solids, and by replacing sour components such as citric acid contained in the transparent tomato juice with bicarbonate or carbonate. Furthermore, when the substituted bicarbonate or carbonic acid escapes as carbon dioxide gas, the viscosity is low and the acidity is reduced as compared with the case where it is not. Therefore, by preparing a tomato-containing beverage using such deacidified tomato juice, the viscosity of the obtained tomato-containing beverage and the acidity or acidity are easily reduced with good reproducibility.

  In addition, since deacidified tomato juice can be concentrated or diluted as necessary and used, it is not particularly limited. From the viewpoint of further increasing the viscosity reduction of tomato-containing beverages, the viscosity is 0 to 150 cP. Is preferred. Here, the viscosity of the deoxidized tomato juice is calculated in terms of tomato straight Brix 4.5. Moreover, the viscosity of 0 means that the viscosity is less than 0.5 and includes those below the detection limit. Although the minimum of a viscosity is not specifically limited, It is preferable that it is 0.01 cP or more.

Hereinafter, the tomato-containing beverage of this embodiment will be described.
The tomato-containing beverage of the present embodiment contains a tomato fruit-derived material as a main raw material, and tomato juice or a concentrate thereof (including these diluted reduced products) and the deacidified tomato juice described above. And at least.

When the present inventors prepared a tomato-containing beverage having the above-described configuration, a tomato-containing beverage that is exceptionally easy to drink and has a sweet taste like a fruit tomato and a sour taste of tomato, which is rich in taste, is simple with good reproducibility. Turned out to be realized. The details of the mechanism of action that produces this effect are not yet clear, but are estimated as follows, for example.
That is, in order to make the sourness of the tomato-containing beverage inconspicuous, it is considered that the sugar content (Brix) is simply increased by using a high-concentration tomato juice (concentrated tomato). However, in this case, the viscosity becomes very high and it is not suitable for drinking. Therefore, as described above, in the prior art, tomato-containing beverages with a rich taste and sweetness like fruit tomatoes are blended with high Brix tomato beverages that are high in viscosity and difficult to drink, or fruit juices or vegetable juices other than tomatoes. It is thought that it was implement | achieved only as a tomato mix drink (tomato mix drink close | similar to the said conventional fruit juice drink or vegetable juice drink).
On the other hand, in the tomato-containing beverage of the present embodiment, in addition to the tomato juice generally used (relatively high Brix and a large amount of water-insoluble solids) or its concentrate, unnecessary water-insoluble solid content Since the deacidified tomato juice from which at least a part of it is removed is blended, the sugar content (Brix) can be sufficiently increased while the viscosity is kept relatively low. Moreover, since the acidity or sourness of the deacidified tomato juice is relatively reduced as described above, the sourness of the resulting tomato-containing beverage is suppressed by using this. As a result of these, the sugar content (Brix) is increased, the taste is rich, the acidity is reduced, and the sourness of the tomato is concealed by the so-called sweetness of the tomato itself. However, it is considered that a tomato-containing beverage that has a sweetness like a fruit tomato and has an enhanced ease of drinking has been realized. However, the action is not limited to these.

  Here, tomato juice or its concentrate is as having demonstrated in deoxidized tomato juice. As a suitable example of the tomato juice used as a raw material of the tomato containing drink of this embodiment, or its concentrate, tomato paste and transparent tomato juice other than the deoxidized tomato juice mentioned above are mentioned.

  In addition, a tomato paste means a thing with a salt-free soluble solid content of 24% or more among said concentrated tomatoes. The tomato paste can be concentrated or diluted as necessary and is not particularly limited. However, from the viewpoint of ease of handling at the time of beverage production, a tomato paste having a salt-free soluble solid content of 24 to 40% is preferable. On the other hand, in this specification, tomato puree means a salt-free soluble solid content of 8% or more and less than 24% among the concentrated tomatoes.

  Preparation of said tomato paste can be suitably performed by a well-known method in this industry, and is not specifically limited. For example, according to a conventional method, the tomato can be obtained by crushing and squeezing or squeezing, concentrating the tomato juice obtained by removing the skin and seeds, etc. It can also be obtained by concentrating, and furthermore, a commercially available tomato paste can also be used. In addition, a tomato paste can be used individually by 1 type or in combination of 2 or more types.

  Moreover, the tomato-containing beverage of the present embodiment is a transparent tomato juice other than the above-described deoxidized tomato juice, more specifically, a transparent tomato juice that has not been subjected to the above-described deoxidation treatment, and other than the above-described deoxidation treatment. Transparent tomato juice (hereinafter, also referred to as “deacidified tomato juice X”) deoxidized by the above method may be contained.

  Here, the deoxidation treatment in the deacidified tomato juice X means a treatment for removing or reducing hydroxy acids such as citric acid that can be contained in the transparent tomato juice. Since the hydroxy acid can function as a sour component in the tomato-containing beverage, the content of the sour component relative to the total amount of the tomato-containing beverage is reduced by including the deacidified tomato juice X from which this hydroxy acid has been removed or reduced. As a result, the acidity of the tomato is suppressed, and the original sweetness of the tomato tends to stand out more. In addition, deacidified tomato juice X can be used alone or in combination of two or more.

  The preparation of deacidified tomato juice X can be appropriately performed by applying a known technique, and is not particularly limited. For example, the hydroxy acid in the transparent tomato juice described above can be removed or reduced by applying a salt exchange method, a chelating method, a decomposition treatment method using an enzyme, or the like.

  In the tomato-containing beverage of the present embodiment, the weight of tomato paste and transparent tomato juice (the sum of the deoxidized tomato juice described above, the transparent tomato juice not subjected to the deoxidation treatment described above, and the deoxidized tomato juice X) The ratio is not particularly limited, but is preferably 1.5 to 4.5. Here, in this specification, the weight ratio is calculated in terms of tomato straight Brix 4.5. By including tomato paste and transparent tomato juice in the above weight ratio, it is possible to easily obtain a tomato-containing beverage having a rich taste, sweetness like fruit tomatoes, and reduced tomato acidity with good reproducibility. it can. From the viewpoint of further increasing the balance of sweetness, sourness, and rich taste of tomato, the weight ratio of tomato paste and transparent tomato juice is preferably 2.5 to 3.5.

  Moreover, it is preferable that the tomato containing drink of this embodiment contains a pH adjuster. By adding the pH adjuster, enhancement of acidity due to the pH of the tomato-containing beverage touching the acidic side is suppressed, and the ease of drinking of the tomato-containing beverage tends to be improved. As such a pH adjuster, sodium bicarbonate is preferable. By adopting baking soda as a pH adjuster, in addition to the pH adjusting function described above, the tomato taste (blue odor, fresh odor, etc.) is further relaxed and the ease of drinking tomato-containing beverages tends to improve. .

  Although the content rate of sodium bicarbonate in the tomato-containing beverage of the present embodiment is not particularly limited, it is preferably 0.1 to 5.0 g / L, more preferably 1.0 to 3.0 g / L in terms of solid content. L. When the content ratio of the baking soda is less than 0.1 g / L, the blending effect of the baking soda tends not to be sufficiently exhibited. On the other hand, when the content ratio of baking soda exceeds 5.0 g / L, the flavor is blurred and sharpness is lost, the original flavor of tomato tends to be impaired, and the sodium content tends to increase.

  Furthermore, the tomato-containing beverage of this embodiment may contain an amino acid. If the amino acid content is high, the umami of the tomato-containing beverage tends to increase. In this case, the total content of glutamic acid and aspartic acid is preferably 0.25 to 0.60% by weight (g / 100 g). When the total content of glutamic acid and aspartic acid is such a high content, the sourness of tomato is suppressed, and the original sweetness of tomato tends to stand out more.

  The tomato-containing beverage of this embodiment may contain other components known in the art in addition to the components described above. Examples of such other components include salt juice, vegetable juice and fruit juice other than tomato, and fruit pulp. In addition, examples of components permitted by the JAS standard include fortifiers such as vitamins, zinc, calcium, iron, copper, magnesium and the like, or salts thereof, sugar, honey, natural flavors, and the like. In addition, although it is a non-JAS standard additive, acidulants such as citric acid and sodium citrate, amino acids, pH adjusters, antioxidants, enzymes, stabilizers such as pectin, sugars other than sugar, natural pigments and Colorants such as synthetic dyes, fragrances such as natural fragrances and synthetic fragrances, carbon dioxide and the like can be mentioned. Other ingredients that can be added in this way are also described in, for example, the “Food Labeling Manual” (edited by the Food Labeling Study Group, Central Law Publishing, revised in February 1989). These can be used alone or in combination of two or more.

  From the viewpoint of preventing the original flavor of tomatoes from being impaired and further enhancing the original flavor of tomatoes, the tomato-containing beverage of this embodiment may be substantially free of vegetable juice and / or fruit juice other than tomato. preferable. Here, “substantially free” means that the total content of vegetable juice and fruit juice other than tomato is 0.0 to 5.0% by weight, preferably 0.0 to 3.0% by weight, more preferably, based on the total amount of beverage. Means 0.0 to 1.0% by weight. Those that do not substantially contain vegetable juice and / or fruit juice other than tomato belong to a new market category of pure tomato-containing beverages that have a rich taste and the original sweetness of tomatoes stand out and can be drunk deliciously as a beverage form, Excellent appeal to consumers.

  The tomato-containing beverage of the present embodiment preferably has a viscosity adjusted to 350 to 1000 cP, more preferably 350 to 600 cP. This low viscosity tends to increase the ease of drinking.

  Moreover, it is preferable that the tomato containing drink of this embodiment is adjusted to pH 4.4-4.8, More preferably 4.5-4.6. The tomato-containing beverage of the present embodiment in this range is particularly rich in taste and the sweetness inherent in tomatoes stands out and can be drunk particularly deliciously as a beverage form. In addition, since the pH too high tends to require a strong sterilization treatment from the viewpoint of hygiene, it is not preferable from the viewpoint of productivity and economy, and there is a strong burn, heating odor and burnt odor accompanying this sterilization treatment. Therefore, also from these viewpoints, the pH of the tomato-containing beverage of the present embodiment is preferably adjusted within the range of 4.4 to 4.8.

  The tomato-containing beverage of the present embodiment preferably has a sugar content of 7.0 to 13.0 and a sugar acid ratio of 19.0 to 30.0. In addition, from the viewpoint of further increasing the balance of sweetness, sourness, and rich taste of tomato, the sugar content is 9.0 to 13.0, and the sugar acid ratio is 19.0 to 30.0. More preferred.

  Now, the tomato-containing beverage of this embodiment is blended with tomato juice or concentrate thereof and deacidified tomato juice, and if necessary, transparent tomato juice or deacidified tomato juice X or other components described above. Can be obtained. At this time, the viscosity, pH, sugar content, acidity, sugar acid ratio, etc. of the tomato-containing beverage can be adjusted by appropriately adjusting the type and blending amount of the tomato fruit-derived product used as the main ingredient, and / or other above-mentioned It can adjust by adjusting suitably the kind and compounding quantity of a component. In addition, the compounding method of each component can be suitably set according to the kind and property of a component to be used, a compounding ratio, etc., and is not specifically limited.

  When blending each component, a treatment known in the art may be performed as necessary. Such known processes include, for example, removal of coarse components by filtration, sieving or sieving, dilution or concentration for adjusting sugar content, mixing or kneading using a mixer or kneader, A homogenization treatment using a homogenizer or the like, an enzyme treatment, a heat treatment and the like can be mentioned, but the invention is not particularly limited thereto. Moreover, these well-known processes can be performed individually or in combination.

  And the tomato containing drink of a container can be obtained by enclosing the tomato containing drink of this embodiment in a container according to a conventional method.

  The container can be appropriately selected from those known in the art and is not particularly limited. Specific examples thereof include paper containers, transparent or translucent bottles, transparent or translucent plastic containers such as PET bottles, and metal cans such as steel cans and aluminum cans. The shape and color of the container are not particularly limited, and can be appropriately determined according to a distribution form and consumer needs.

  Enclosing the tomato-containing beverage in a container can be performed by a method known in the art. For example, by using a heat sterilizer such as a plate type heater or a tube type heater and holding at a temperature of 85 to 98 ° C. for 10 to 60 seconds for heat sterilization, and then filling the container according to a conventional method A canned tomato-containing beverage can be obtained.
