Description

本発明は、食塩を共存させることによってポリフェノール類が持つ抗酸化作用を維持できる食塩含有食品加工残液及び残渣配合飼料に関する。   The present invention relates to a salt-containing food processing residual liquid and a residue-containing feed that can maintain the antioxidant action of polyphenols in the presence of salt.

酸素複素環構造を持つ植物成分の一つであるフラボノイドは、そのナフトキノン環などに複数のフェノール性水酸基を有しているので、総称してポリフェノールと呼ばれている。   Flavonoids which are one of the plant components having an oxygen heterocyclic structure have a plurality of phenolic hydroxyl groups in their naphthoquinone rings and are collectively called polyphenols.

ポリフェノール類には、カテキン類、アントシアニン類、フラボン類、フラボノール類、フラバノン類、カルコン類、イソフラボン類など多数の種類があり、その良好な酸化還元反応性から、活性酸素類に対する抗酸化機能を有している。これらのポリフェノール類は、本来植物成分として含有されていたもののほかに、発酵などの加工過程でも生成され、加工残液や残渣中に比較的多く含まれている場合がある。ポリフェノール類は植物性ではなく、動物性発酵残液や残渣中にも、通常に含有されている。   There are many types of polyphenols such as catechins, anthocyanins, flavones, flavonols, flavanones, chalcones, and isoflavones, and they have an antioxidant function against active oxygens due to their good redox reactivity. is doing. In addition to those originally contained as plant components, these polyphenols are also produced during processing such as fermentation, and may be contained in a relatively large amount in processing residual liquids and residues. Polyphenols are not plant-based and are usually contained in animal fermentation residue and residue.

ところで、近年、資源確保及び環境保全の観点から、廃棄物のリサイクルが活発に行われているが、加工食品の製造工程から副生する植物等の加工残液及び残渣についても再資源化の試みがなされている。   By the way, in recent years, waste recycling has been actively carried out from the viewpoint of securing resources and environmental conservation. However, it is also an attempt to recycle residual processing liquids and residues of plants and other by-products from the manufacturing process of processed foods. Has been made.

しかし、例えば梅干等の生産時に副生される梅残液のような食塩含有食品加工残液は、高濃度に食塩を含有するが故に、直接利用や加工が困難であり、このことが再資源化の妨げとなり、従来は、廃棄され、環境汚染の原因となっていた。   However, salt-containing food processing residue, such as plum residue produced as a by-product during the production of umeboshi, is difficult to use and process directly because it contains salt at a high concentration. In the past, it was discarded and caused environmental pollution.

これに対して、特許文献1では、梅干の生産時に副生される梅酢を、真空乃至減圧濃縮、加熱濃縮し、電気透析処理により脱塩して得られる脱塩濃縮梅酢を、養魚用飼料に配合する技術を開示している。   On the other hand, in patent document 1, the ume vinegar produced as a by-product at the time of the production of umeboshi is vacuumed or concentrated under reduced pressure, heated and concentrated, and desalted and concentrated ume vinegar obtained by desalting by electrodialysis is used as feed for fish farming A technique for blending is disclosed.

特開2008−206501号公報JP 2008-206501 A

本発明者は、食品加工残液に含まれるポリフェノールに着目し、食品加工残液を飼料に配合して抗酸化作用を付与することを検討した。   The present inventor paid attention to polyphenols contained in the food processing residual liquid and studied to add the food processing residual liquid to the feed to impart an antioxidant action.

ところで、ポリフェノールのベンゼン環上にあるフェノール性水酸基は、酸化還元電位が低く、容易に自身が酸化され、活性酸素を捕捉する。これが、ポリフェノールが抗酸化性を示す理由である。   By the way, the phenolic hydroxyl group on the benzene ring of polyphenol has a low redox potential and is easily oxidized to capture active oxygen. This is the reason why polyphenols exhibit antioxidant properties.

しかし、同時に、酸化された状態のポリフェノール(ポリフェノール酸化態)は、抗酸化作用を有さないばかりか、活性酸素の発生源にも成り得ることに注意しなければならない。   At the same time, however, it should be noted that the oxidized polyphenols (polyphenol oxidation state) have not only an antioxidant action but can also be a source of active oxygen.

即ち、活性酸素の発生を排除して、抗酸化作用を好適に得るためには、ポリフェノールを還元された状態(ポリフェノール還元態)に保つことが極めて重要である。   That is, in order to eliminate the generation of active oxygen and to obtain an antioxidant effect suitably, it is extremely important to keep the polyphenol in a reduced state (polyphenol reduced state).

本発明者は、上記の知見に加えて、食品加工工程から副生する食品加工残液及び残渣においては、ポリフェノールを還元態に保つことが特に困難となることを見出した。   In addition to the above findings, the present inventor has found that it is particularly difficult to keep polyphenols in a reduced state in the food processing residual liquid and residues by-produced from the food processing step.

即ち、食品の中でも、主に植物は、通常、ポリフェノールと共に、ポリフェノールオキシダーゼを含有している。   That is, among foods, plants mainly contain polyphenol oxidase together with polyphenol.

ポリフェノールオキシダーゼは、ポリフェノール酸化態の形成を促進する作用を有する酵素である。   Polyphenol oxidase is an enzyme having an action of promoting the formation of a polyphenol oxidation state.

加工前の植物において、ポリフェノールとポリフェノールオキシダーゼとは、隔離された状態で貯蔵されている。そのため、ポリフェノールオキシダーゼによるポリフェノール酸化態の形成はほとんど進行しない。   In the plant before processing, polyphenol and polyphenol oxidase are stored in an isolated state. Therefore, the formation of the polyphenol oxidation state by polyphenol oxidase hardly proceeds.

ところが、植物の加工を行うと、植物の組織が破壊されるため、隔離された状態で貯蔵されていたポリフェノールとポリフェノールオキシダーゼと酸素とが接触可能な状態となる。この結果、ポリフェノールオキシダーゼによるポリフェノール酸化態の形成が促進される。   However, when the plant is processed, the tissue of the plant is destroyed, so that the polyphenol, the polyphenol oxidase, and the oxygen stored in the isolated state can be brought into contact with each other. As a result, formation of a polyphenol oxidation state by polyphenol oxidase is promoted.

特に植物加工残液及び残渣中においては、ポリフェノールとポリフェノールオキシダーゼとの接触頻度が極めて高いため、ポリフェノール酸化態の形成が著しく促進される。   In particular, in the plant processing residue and residue, the contact frequency between polyphenol and polyphenol oxidase is extremely high, so that the formation of the polyphenol oxidation state is remarkably promoted.

以上は植物加工残液及び残渣におけるポリフェノールを還元態に保つことが特に困難となる理由であるが、このことは植物以外の食品でも類推できる。   The above is the reason why it is particularly difficult to keep the polyphenols in the plant processing residue and residue in a reduced state, and this can be inferred from foods other than plants.

この結果、食品加工残液及び残渣を飼料に配合した場合は、抗酸化作用に劣るばかりか、活性酸素の発生源に成り得るポリフェノール酸化態が多く生成して、これらが抗酸化作用とは逆の作用、即ち酸化性を付与する恐れすらある。   As a result, when food processing residual liquid and residue are mixed with feed, not only are they inferior in antioxidant activity, but many polyphenol oxidation forms that can be a source of active oxygen are generated, which is contrary to antioxidant activity. There is even a possibility of imparting the action of, i.e., oxidizing property.

本発明者は、ポリフェノールを還元態に保つことについて鋭意検討し、食塩含有食品加工残液に含有される食塩に着目した。   This inventor earnestly examined about keeping a polyphenol in a reduced state, and paid attention to the salt contained in salt-containing food processing residual liquid.

即ち、食塩から生成する塩化物イオン(Cl)は、ポリフェノールオキシダーゼの活性を阻害して、ポリフェノールの酸化を防止する機能を有する。一例として、リンゴの切り口に食塩を含ませることにより、褐色化が抑えられることはよく知られている。 That is, chloride ions (Cl ) generated from salt have a function of inhibiting the activity of polyphenol oxidase and preventing the oxidation of polyphenol. As an example, it is well known that browning can be suppressed by adding salt to the cut end of an apple.

本発明者は、食塩含有食品加工残液及び/又は残渣を配合してなる食塩含有食品加工残液及び残渣配合飼料において、食塩含有食品加工残液及び残渣に由来する食塩をある程度残存させることにより、ポリフェノール還元態を保持して、ポリフェノールの抗酸化作用を維持できることを見出して、本発明を完成させた。   The inventor of the present invention has a salt-containing food processing residual liquid and / or a residue-containing feed obtained by adding salt-containing food processing residual liquid and / or a residue to a certain extent so that salt derived from the salt-containing food processing residual liquid and the residue remains to some extent. The present invention has been completed by finding that the polyphenol reduced state can be maintained and the antioxidant action of the polyphenol can be maintained.

特許文献1には、上述したポリフェノールの抗酸化作用の維持のためにある程度の食塩を残存させるという思想が開示されていない。また電気透析処理によって、食塩含量が1%程度になるまで高度に脱塩を行おうとすると、高コストである。   Patent Document 1 does not disclose the idea of leaving a certain amount of salt to maintain the above-described antioxidant action of polyphenols. In addition, if desalting is performed to a high degree until the salt content reaches about 1% by electrodialysis, the cost is high.

そこで、本発明の課題は、ポリフェノール還元態を保持できる食塩含有食品加工残液及び残渣配合飼料を提供することにある。   Then, the subject of this invention is providing the salt containing food processing residual liquid and residue mixing | blending feed which can hold | maintain a polyphenol reduced state.

また本発明の他の課題は、ポリフェノールの抗酸化作用を維持できる食塩含有食品加工残液及び残渣配合飼料を提供することにある。   Moreover, the other subject of this invention is providing the salt containing food processing residual liquid and residue mixing feed which can maintain the antioxidant action of polyphenol.

さらに本発明の他の課題は、以下の記載によって明らかとなる。   Furthermore, the other subject of this invention becomes clear by the following description.

実施例2の結果を示す図The figure which shows the result of Example 2

本発明に用いられる食塩含有食品加工残液及び残渣としては、特に植物性のものに限定されないが、梅残液及び残渣、野菜等下漬液、食品発酵残渣等を好ましく例示できる。   The salt-containing food processing residual liquid and residue used in the present invention are not particularly limited to plant-based ones, but preferred examples include ume residual liquid and residues, vegetable underpoured liquids, food fermentation residues, and the like.

上述した食塩含有食品加工残液は、そのままの状態で飼料に配合しても、抗酸化作用が十分に得られないため、これを濃縮し、ポリフェノール類の濃度を上昇させる必要がある。   Even if it mix | blends the salt-containing food processing residual liquid mentioned above with feed as it is, since an antioxidant effect is not fully acquired, this needs to be concentrated and the density | concentration of polyphenols needs to be raised.

そこで、本発明において、上述した食塩含有食品加工残液及び残渣は、濃縮工程に供される。   Therefore, in the present invention, the salt-containing food processing residue and residue described above are subjected to a concentration step.

濃縮によって、食塩含有食品加工残液中におけるポリフェノール類濃度が上昇し、抗酸化作用が向上する。このとき、食塩も同時に濃縮(飽和状態)されるため、向上した抗酸化作用は好適に保持される。   Concentration increases the concentration of polyphenols in the salt-containing food processing residual liquid and improves the antioxidant effect. At this time, the salt is also concentrated (saturated) at the same time, so that the improved antioxidant action is suitably maintained.

また、濃縮によって、食塩含有食品加工残液及び残渣の腐敗防止性が向上する。即ち、本発明に用いられる食塩含有食品加工残液及び残渣は、酸化防止用飼料に抗酸化作用を付与すると同時に、栄養源をも付与するものであるが、この栄養源が腐敗微生物によって利用された場合は腐敗を生じる。腐敗は、家畜や養魚の嗜好性を著しく低下させる等の深刻な問題を生じる。濃縮を行うことにより、含水率が低下し、更に、クエン酸等の腐敗防止成分の濃度が上昇するので、腐敗微生物の生育が阻害され、腐敗が防止される効果も得られる。   Concentration improves the salt-containing food processing residue and the anti-corruption property of the residue. That is, the salt-containing food processing residue and residue used in the present invention provide an antioxidant action to the antioxidant feed and at the same time provide a nutrient source, but this nutrient source is utilized by the spoilage microorganisms. If it does, it will rot. Corruption causes serious problems such as significantly reducing the preference of livestock and fish farming. By concentrating, the moisture content decreases, and the concentration of anti-corrosion components such as citric acid increases, so that the growth of spoilage microorganisms is inhibited and the effect of preventing spoilage is also obtained.

更に、濃縮により食塩含有食品加工残液及び残渣は減容されるため、輸送時の取扱い性や積載量を向上することができる。   Furthermore, since the salt-containing food processing residual liquid and the residue are reduced by concentration, the handling property and loading capacity during transportation can be improved.

濃縮液中において、食塩により還元状態を保持されたポリフェノール類が、効率よく酸素を捕捉するため、酸素により脂質が酸化されることが防止され、過酸化脂質の生成を抑制できる。この効果は、濃縮液を飼料に配合した後も継続されるため、飼料中の脂質が酸化されることによる過酸化脂質の生成をも抑制できる。   In the concentrated solution, polyphenols maintained in a reduced state by sodium chloride efficiently capture oxygen, so that lipid is prevented from being oxidized by oxygen, and production of lipid peroxide can be suppressed. Since this effect is continued even after blending the concentrate into the feed, the production of lipid peroxide due to oxidation of the lipid in the feed can also be suppressed.

本発明の酸化防止用飼料中において、過剰な食塩は、家畜や養魚の嗜好性を低下させ、また、過剰な塩分摂取は生育の障害になる。そこで、食塩は、抗酸化作用の維持という重要な役割を維持できるように、ある程度残存させるように除去する必要がある。   In the antioxidant feed of the present invention, excessive salt reduces the palatability of livestock and fish, and excessive salt intake is an obstacle to growth. Therefore, it is necessary to remove the salt so that it remains to some extent so that the important role of maintaining the antioxidant effect can be maintained.

上記の理由から、本発明において、食塩含有食品加工残液を濃縮して得られる食塩含有食品加工残液及び残渣濃縮物は、残存する食塩濃度が、4重量%以上、好ましくは4.5〜25重量%、より好ましくは5〜10重量%である。食塩含有量はICP発光分析法によってNaを定量し、NaClに換算する。 For the above reasons, in the present invention, the salt-containing food processing residual liquid and the residue concentrate obtained by concentrating the salt-containing food processing residual liquid have a residual salt concentration of 4% by weight or more, preferably 4.5 to 25% by weight, more preferably 5 to 10% by weight. For the salt content, Na + is quantified by ICP emission spectrometry and converted to NaCl.

また、ポリフェノール類を0.05重量%以上含有することが好ましく、より好ましくは0.1重量%以上含有する。ポリフェノール類は、酸化還元測定法もしくはICP発光分析法で測定する。   Moreover, it is preferable to contain polyphenols 0.05weight% or more, More preferably, 0.1weight% or more is contained. Polyphenols are measured by a redox measurement method or an ICP emission analysis method.

ポリフェノール類は高濃度ほど飼料化の際の抗酸化機能が増加するが、5重量%を超えるとその効果は飽和してくる。ポリフェノール類濃度が5重量%を超える場合は、他の配合材混合によってポリフェノール類濃度を5重量%以下に抑え、製品としての飼料量を増量させることも好ましい。   The higher the concentration of polyphenols, the higher the antioxidant function at the time of feeding, but the effect becomes saturated when it exceeds 5% by weight. When the concentration of polyphenols exceeds 5% by weight, it is also preferable to suppress the concentration of polyphenols to 5% by weight or less by mixing other ingredients and increase the amount of feed as a product.

濃度調整手段としては、食塩、ポリフェノール共に濃縮法や膜を用いる方法等が挙げられる。   Examples of the concentration adjusting means include a concentration method and a method using a membrane for both salt and polyphenol.

本発明の濃縮工程に用いられる濃縮手段としては、特に限定されるものではないが、蒸発缶を好ましく例示できる。   Although it does not specifically limit as a concentration means used for the concentration process of this invention, An evaporator can be illustrated preferably.

濃縮工程として蒸発缶を用いれば、濃縮に伴って析出する過飽和食塩を、後段の固液分離工程により除去することで、食塩含有食品加工残液濃縮物中の食塩含有量を、目的の重量%の範囲に調整することができる。   If an evaporator is used as the concentration step, the supersaturated salt that precipitates with concentration is removed by the subsequent solid-liquid separation step, so that the salt content in the salt-containing food processing residue concentrate is reduced to the desired weight%. Can be adjusted within the range.

固液分離工程に用いられる固液分離手段としては、特に限定されるものではないが、遠心分離機等を好ましく例示できる。   The solid-liquid separation means used in the solid-liquid separation step is not particularly limited, but a centrifuge or the like can be preferably exemplified.

また、固液分離工程において、濃縮液から分離された食塩は、牛塩等の配合飼料として有効利用することができる。   Moreover, the salt isolate | separated from the concentrate in a solid-liquid separation process can be effectively utilized as compound feed, such as a beef salt.

食塩含有食品加工残液濃縮物は、飼料に配合することで、食塩含有食品加工残液配合飼料が得られる。   The salt-containing food processing residual liquid concentrate is mixed with the feed to obtain a salt-containing food processing residual liquid-containing feed.

前記飼料としては、特に限定されるものではないが、エクストルーダ処理した固形飼料(EP)を好ましく例示できる。   Although it does not specifically limit as said feed, Extruder-processed solid feed (EP) can be illustrated preferably.

EPとしては、粉末飼料を二軸のエクストルーダなどで加圧成型したものが好適である。   As EP, the thing which pressure-molded the powder feed with the biaxial extruder etc. is suitable.

EPの形状としては、径2〜10mmの押し出し成形機によって加圧成形された円盤状、柱状の固形物であり、その径は対象飼料によって選択される。このEPは加圧及び自らの粘着性によって、運搬、給餌のときに形状を維持できるだけの飼料として硬すぎないまでの圧縮強度を有するように成型され、その強度は、荷重式の圧縮試験で0.5〜5.0kg/cmである。また、嵩比重が0.3〜0.7、含水率が10重量%以下であることが好ましい。この範囲のEPであれば、濃縮液の吸収性に優れ、効率的に食塩含有食品加工残液及び残渣配合飼料を得ることができる。 The shape of the EP is a disk-like or columnar solid that is pressure-formed by an extrusion molding machine having a diameter of 2 to 10 mm, and the diameter is selected depending on the target feed. This EP is molded so as to have a compressive strength that is not too hard as a feed that can maintain its shape during transportation and feeding due to pressure and self-adhesiveness. 5 to 5.0 kg / cm 2 . The bulk specific gravity is preferably 0.3 to 0.7 and the water content is preferably 10% by weight or less. If it is EP of this range, it is excellent in the absorbability of a concentrate and can obtain a salt containing food processing residual liquid and a residue mixing feed efficiently.

食塩含有食品加工残液及び残渣濃縮物を上記固形飼料と配合する際の配合比は、食品加工残液及び残渣濃縮物が、乾燥重量として5〜50重量%となるように設定する。   The blending ratio when the salt-containing food processing residual liquid and the residue concentrate are combined with the solid feed is set so that the food processing residual liquid and the residue concentrate are 5 to 50% by weight as dry weight.

前記配合比が5重量%未満の場合は、抗酸化作用が劣り、50重量%を超える場合は、飼料中の食塩含有率が過多となるため、家畜又は養魚の嗜好性低下を招く。   When the blending ratio is less than 5% by weight, the antioxidant effect is inferior, and when it exceeds 50% by weight, the salt content in the feed is excessive, leading to a decrease in palatability of livestock or fish farming.

本発明の食塩含有食品加工残液及び残渣配合飼料は、抗酸化作用により過酸化脂質の生成が抑制される。   The salt-containing food processing residual liquid and the residue-blended feed of the present invention are inhibited from producing lipid peroxide by an antioxidant action.

特に養魚用の固形飼料は、養魚の高い脂質要求性を満たすために10〜40%程度の粗脂肪分を含有している。また、養魚用の固形飼料に粗脂肪分を提供するために用いられる魚油中には、易酸化性の脂質である高度不飽和脂肪酸の含有量も多い。そのため、従来、養魚用の固形飼料においては、過酸化脂質の生成が大きな問題となっていた。これに対して、本発明の食塩含有食品加工残液及び残渣配合飼料は、これら粗脂肪分に対する抗酸化作用により、経時的またはエクストルーダー等による加工による、過酸化脂質の生成を抑制できるため、嗜好性が高く、品質に優れるものである。   In particular, solid feed for fish farming contains about 10 to 40% of crude fat in order to satisfy the high lipid requirements of fish farming. In addition, the content of highly unsaturated fatty acids, which are easily oxidizable lipids, is high in fish oil used to provide crude fat in solid feed for fish farming. Therefore, conventionally, production of lipid peroxide has been a big problem in solid feed for fish farming. On the other hand, the salt-containing food processing residual liquid and the residue-blended feed of the present invention can suppress the production of lipid peroxides over time or by processing with an extruder or the like due to the antioxidant effect on these crude fats, The taste is high and the quality is excellent.

また、本発明によれば、従来、廃棄され、環境汚染の原因となっていた食塩含有食品加工残液及び残渣を再資源化でき、また特許文献1の電気透析処理のような高コストな工程を含まないため、低コストに環境保護に貢献することができる。   In addition, according to the present invention, salt-containing food processing residual liquid and residue that have been discarded and caused environmental pollution can be recycled, and a high-cost process such as the electrodialysis treatment of Patent Document 1 is also possible. Can be contributed to environmental protection at low cost.

以下に、本発明の実施例を説明するが、本発明はかかる実施例によって限定されない。   Examples of the present invention will be described below, but the present invention is not limited to such examples.

実施例1(EP飼料)
養魚用EP成形(製造)時の脂質過酸化物生成の食塩濃度依存性について検討した。
Example 1 (EP feed)
The salt concentration dependence of lipid peroxide formation during EP molding (manufacturing) for fish farming was examined.

飼料配合材(カタクチイワシ魚粉、カタクチイワシ魚油、小麦粉、大豆、油粕、ビタミン類)、麦焼酎粕濃縮液及び食塩を加えて混練し、エクストルーダにて成形し、成形物を分析した。   A feed compounding material (anchovy fish meal, anchovy fish oil, wheat flour, soybeans, oil cake, vitamins), a barley shochu concentrate and sodium chloride were added and kneaded, molded with an extruder, and the molded product was analyzed.

ポリフェノール類濃度は鉄3価イオンを滴定試薬とする酸化還元滴定法、脂質過酸化物濃度はヨードメトリー、食塩濃度は塩化物イオンの沈殿測定(電位差測定)によって把握した。   The concentration of polyphenols was determined by the oxidation-reduction titration method using iron trivalent ions as a titration reagent, the lipid peroxide concentration was determined by iodometry, and the salt concentration was determined by chloride ion precipitation measurement (potential difference measurement).

その結果を表1に示す。   The results are shown in Table 1.

Figure 2012205554
Figure 2012205554

上記表1より、試料1、2は、食塩含有量を5重量%以上含有することにより、ポリフェノール類が0.05重量%以上含有する飼料を製造することができた。それにより、試料3に比べて、脂質過酸化物含有量が大幅に少なく、ポリフェノールの抗酸化作用が維持できていることがわかる。   From Table 1 above, Samples 1 and 2 were able to produce feed containing 0.05 wt% or more of polyphenols by containing 5 wt% or more of salt content. Thereby, compared with the sample 3, it turns out that lipid peroxide content is significantly less and the antioxidant action of polyphenol is maintained.

梅残液(1)と、その梅残液(1)を電気透析処理によって脱塩した脱Na梅残液(2)、(3)の分析値を表2に示す。脱Na梅残液(2)と(3)は、脱塩処理による食塩濃度が異なり、脱Na梅残液(2)は実施例であり、(3)は比較例である。
Example 2
Table 2 shows the analytical values of the ume residue (1) and the desalted Na ume residue (2) and (3) obtained by desalting the ume residue (1) by electrodialysis. The Na-desalted solution (2) and (3) have different salt concentrations due to desalting treatment, the desalted-Na plum residue (2) is an example, and (3) is a comparative example.

食塩含有量とポリフェノール含有量の相関を明らかにするために、上記表2の(1)、(2)、(3)の各々の液を、50℃の温度環境で攪拌し、経時的にサンプリングして、含有ポリフェノール濃度を測定した。   In order to clarify the correlation between the salt content and the polyphenol content, each solution of (1), (2) and (3) in Table 2 above was stirred in a temperature environment of 50 ° C. and sampled over time. Then, the contained polyphenol concentration was measured.

そのポリフェノール濃度の変化を図1に示す。   The change in the polyphenol concentration is shown in FIG.

図1より、食塩含有量とポリフェノール含有量の相関関係が示され、(1)及び(2)の液では、ポリフェノール濃度が高く維持され、食塩が抗酸化機能の維持に寄与することがわかる。一方、(3)の液では、脱塩後の食塩濃度が3.2重量%であったために、ポリフェノール濃度は経時的に急激に低下して、残存食塩による、ポリフェノール還元態を保持できておらず、その結果、ポリフェノールの抗酸化作用を維持できないことがわかる。   FIG. 1 shows the correlation between the salt content and the polyphenol content. In the solutions (1) and (2), the polyphenol concentration is maintained high, and it can be seen that the salt contributes to the maintenance of the antioxidant function. On the other hand, in the liquid (3), since the salt concentration after desalting was 3.2% by weight, the polyphenol concentration rapidly decreased with time, and the polyphenol reduced state by the residual salt could not be maintained. As a result, it can be seen that the antioxidant action of polyphenols cannot be maintained.
