Description
本発明は、果実の防カビ方法、及び果実の防カビ用組成物に関する。
The present invention relates to a fruit mold prevention method and a fruit mold prevention composition.
果実の生育中あるいは収穫後にカビが発生した果実は、腐敗若しくは変敗等の品質劣化のために出荷することができないために廃棄となることが多く、結果として、出荷数（歩留まり）が減少する。特に、収穫後に出荷調整又は熟成のために一定期間に亘って倉庫内で貯蔵される果物については、貯蔵時間の経過と共に一部の果物からカビが発芽し、増殖及び伝染し、ひいては腐敗や変敗を引き起こすことが多々ある。
Fruits that are moldy during fruit growth or after harvest are often discarded because they cannot be shipped due to quality degradation such as decay or deterioration, resulting in a decrease in the number of shipments (yield). . In particular, for fruits that are stored in a warehouse for a certain period of time for shipment adjustment or ripening after harvesting, mold germinates, grows and spreads from some fruits over time, and eventually decays or changes. Often causes defeat.
カビの発生による社会的、及び経済的損出は大きいことから、果実におけるカビの発生を防除することは、極めて重要である。一方、一般的な防カビ方法では、収穫前又は収穫後の果実に対して防カビ剤を施用することが多い。
∙ Since the social and economic loss due to the occurrence of mold is large, it is extremely important to control the occurrence of mold in fruits. On the other hand, in a general antifungal method, an antifungal agent is often applied to fruits before harvesting or after harvesting.
上記の懸念を踏まえて、これまでに様々な防カビ剤が開発されてきており、一例を挙げて説明すると、特許文献１には、「カピリン及びポリフェノールを含有することを特徴とする青果物用腐敗防止組成物」、及びその利用方法が記載されている（特許文献１の「請求項１」、及び明細書中の「実施例」の参照）。上記の特許文献１に記載の青果物用腐敗防止組成物によれば、カビの発生及び増殖を抑制して青果物の腐敗を抑制することができ、その結果、青果物の商品価値の低下を防止することが可能となる。
Based on the above-mentioned concerns, various antifungal agents have been developed so far, and an example will be described. Patent Document 1 states that “a spoilage for fruits and vegetables characterized by containing capilin and polyphenol”. Prevention composition "and its utilization method are described (see" Claim 1 "of Patent Document 1 and" Example "in the specification). According to the anti-corruption composition for fruits and vegetables described in Patent Document 1 described above, the occurrence and growth of mold can be suppressed, and the decay of fruits and vegetables can be suppressed, and as a result, the decline in the commercial value of fruits and vegetables can be prevented. Is possible.
防カビ剤の使用に関して、食品の安全性を配慮すると、単位収量当たりの防カビ剤の使用量（散布量）を増やすことが難しくなるが、使用量を控えると十分な防カビ効果が得られない可能性がある。また、特許文献１では、防カビ効果を向上させるために、界面活性剤及び脂肪酸グリセリド等の添加剤を青果物用腐敗防止剤中に更に追加している。その一方で、防カビ剤の使用量増加又は組成変更（具体的には、添加物の追加）を行わなくとも、防カビ効果を向上させることが求められている。
Considering food safety with regard to the use of antifungal agents, it becomes difficult to increase the amount of antifungal agent used per unit yield (spreading amount), but sufficient antifungal effects can be obtained if the amount used is reduced. There is no possibility. Moreover, in patent document 1, in order to improve an antifungal effect, additives, such as surfactant and a fatty-acid glyceride, are further added in the anti-corrosion agent for fruits and vegetables. On the other hand, it is required to improve the antifungal effect without increasing the amount of antifungal agent used or changing the composition (specifically, adding an additive).
そこで、本発明は、防カビ剤の使用量増加及び組成変更を行わなくとも、果実に対する防カビ効果を向上させることが可能な果実の防カビ方法、及び果実の防カビ用組成物を提供することを課題とする。
Accordingly, the present invention provides a fruit mold prevention method and a fruit mold prevention composition that can improve the mold prevention effect on fruits without increasing the amount of use of the fungicide and changing the composition. This is the issue.
本発明者は、上記課題を達成すべく鋭意検討した結果、防カビ剤及びナノバブル水を施用することにより、防カビ剤の使用量を増加したり組成を変更したりしなくても、果実に対する防カビ効果が向上することを見出し、本発明を完成させた。
すなわち、本発明者は、以下の構成により上記課題を達成することができることを見出した。 As a result of intensive studies to achieve the above-mentioned problems, the present inventor applied the antifungal agent and nanobubble water to the fruit without increasing the amount of the antifungal agent used or changing the composition.

液体吐出機３０は、ポンプによって構成され、ナノバブル水の原水（例えば、井戸水）を取り込んで吐出する。気体混入機４０は、圧縮ガスが封入された容器４１と、略筒状の気体混入機本体４２とを有し、液体吐出機３０から吐出された水を気体混入機本体４２内に流しつつ、気体混入機本体４２内に容器４１内の圧縮ガスを導入する。これにより、気体混入機本体４２内で気体混入水が生成されることになる。
ナノバブル生成ノズル５０は、その内部に気体混入水が通過することにより、加圧溶解の原理に従って気体混入水中にナノバブルを発生させるものであり、その構造としては、特開２０１８－１５７１５号公報に記載されたナノバブル生成ノズルと同じ構造が採用できる。ナノバブル生成ノズル５０内に生成されたナノバブル水は、ナノバブル生成ノズル５０の先端から噴出した後、ナノバブル生成装置１０から流出し、不図示の流路内を通じて所定の利用先に向けて送水される。
以上のようにナノバブル生成装置１０では、気体混入機４０が、液体吐出機３０とナノバブル生成ノズル５０の間において、加圧された状態でナノバブル生成ノズル５０に向かって流れる水（原水）に、圧縮ガスを混入させる。これにより、液体吐出機３０の吸込み側（サクション側）で気体を水に混入させるときに生じるキャビテーション等の不具合を回避することができる。また、ガスが加圧（圧縮）された状態で水に混入されるので、ガス混入箇所での水の圧力に抗してガスを混入させることができる。このため、ガス混入箇所において特に負圧を発生させなくとも、ガスを適切に水に混入させることが可能となる。
さらに、液体吐出機３０のサクション側に、井戸又は水道等の水源から供給される水の流路が繋ぎ込まれており、その流路において液体吐出機３０の上流側から液体吐出機３０に流れ込む水の圧力（すなわち、サクション側の水圧）が正圧であるとよい。この場合には、上記の構成がより有意義なものとなる。すなわち、液体吐出機３０の上流側の水圧（サクション圧）が正圧となる場合には、液体吐出機３０の下流側でガスを水に混入させることになるため、液体吐出機３０の下流側でもガスを適切に水に混入させることができるナノバブル生成装置１０の構成がより際立つことになる。 Other nanobubble generation devices that do not intentionally generate radicals include, for example, a liquid discharger that discharges water, a gas mixer that pressurizes and mixes gas into water discharged from the liquid discharger, and A microbubble generator for generating microbubbles in water by passing water mixed with gas inside, wherein the gas mixer includes the liquid ejector and the microbubble generator There is a fine bubble generating device that pressurizes and mixes gas into the liquid flowing toward the fine bubble generator in a pressurized state between the vessels. Specifically, the nanobubble generator shown in FIG.
Thenanobubble generating device 10 illustrated in FIG. 1 includes a liquid discharger 30, a gas mixing device 40, and a nanobubble generating nozzle 50 therein.
Theliquid discharger 30 is configured by a pump, and takes in and discharges nanobubble water raw water (for example, well water). The gas mixing device 40 includes a container 41 in which compressed gas is sealed and a substantially cylindrical gas mixing device main body 42. While flowing water discharged from the liquid discharge device 30 into the gas mixing device main body 42, The compressed gas in the container 41 is introduced into the gas mixing machine main body 42. As a result, gas-containing water is generated in the gas-mixing machine main body 42.
Thenanobubble generating nozzle 50 generates nanobubbles in the gas-mixed water according to the principle of pressure dissolution by passing the gas-mixed water through the nozzle, and the structure thereof is described in JP-A-2018-15715. The same structure as the nanobubble generating nozzle made can be adopted. The nanobubble water generated in the nanobubble generating nozzle 50 is ejected from the tip of the nanobubble generating nozzle 50, then flows out from the nanobubble generating device 10, and is sent toward a predetermined usage destination through a flow path (not shown).
As described above, in thenanobubble generating device 10, the gas mixing device 40 is compressed into water (raw water) flowing toward the nanobubble generating nozzle 50 in a pressurized state between the liquid discharger 30 and the nanobubble generating nozzle 50. Mix gas. Thereby, it is possible to avoid problems such as cavitation that occur when gas is mixed into water on the suction side (suction side) of the liquid discharger 30. Further, since the gas is mixed in the water in a pressurized (compressed) state, the gas can be mixed against the pressure of the water at the gas mixing location. For this reason, it becomes possible to mix gas into water appropriately, without generating a negative pressure especially in a gas mixing location.
Further, a flow path of water supplied from a water source such as a well or water supply is connected to the suction side of theliquid discharger 30 and flows into the liquid discharger 30 from the upstream side of the liquid discharger 30 in the flow path. The water pressure (that is, the water pressure on the suction side) may be positive. In this case, the above configuration becomes more meaningful. That is, when the water pressure (suction pressure) on the upstream side of the liquid discharger 30 is a positive pressure, the gas is mixed into the water on the downstream side of the liquid discharger 30. However, the configuration of the nanobubble generating apparatus 10 that can appropriately mix the gas into water becomes more prominent.

さらに、液体吐出機３０のサクション側に、井戸又は水道等の水源から供給される水の流路が繋ぎ込まれており、その流路において液体吐出機３０の上流側から液体吐出機３０に流れ込む水の圧力（すなわち、サクション側の水圧）が正圧であるとよい。この場合には、上記の構成がより有意義なものとなる。すなわち、液体吐出機３０の上流側の水圧（サクション圧）が正圧となる場合には、液体吐出機３０の下流側でガスを水に混入させることになるため、液体吐出機３０の下流側でもガスを適切に水に混入させることができるナノバブル生成装置１０の構成がより際立つことになる。 Other nanobubble generation devices that do not intentionally generate radicals include, for example, a liquid discharger that discharges water, a gas mixer that pressurizes and mixes gas into water discharged from the liquid discharger, and A microbubble generator for generating microbubbles in water by passing water mixed with gas inside, wherein the gas mixer includes the liquid ejector and the microbubble generator There is a fine bubble generating device that pressurizes and mixes gas into the liquid flowing toward the fine bubble generator in a pressurized state between the vessels.
