Description

青果物の成熟抑制材Fruit and fruit ripening inhibitor
　本発明は、青果物の成熟抑制材に関する。 The present invention relates to a fruit and fruit ripening inhibitor.
　従来、トマト等の青果物は成熟前に収穫し、流通過程で成熟させ、店頭に陳列して販売することが行われている。ところが、このようにするときには成熟の時期を制御することが難しく、店頭に陳列している間に成熟の最盛期を過ぎると商品価値が低下し、販売価格を下げざるを得ないという問題がある。 Traditionally, fruits and vegetables such as tomatoes are harvested before maturation, matured in the distribution process, and displayed and sold in stores. However, when doing this, it is difficult to control the time of maturity, and there is a problem that the value of the product will drop and the selling price will have to be lowered if it passes the maturity period while it is displayed at the storefront. .
　一方、青果物の成熟には、青果物自体が放出するエチレンが関与していることが知られており、成熟の時期を制御するために、ゼオライト等のエチレン吸着剤を用いることが知られている（例えば、特許文献１参照）。 On the other hand, maturation of fruits and vegetables is known to involve ethylene released by the fruits and vegetables themselves, and it is known to use an ethylene adsorbent such as zeolite in order to control the maturity period ( For example, see Patent Document 1).
特開平１０－４３５８３号公報Japanese Patent Laid-Open No. 10-43583
　しかしながら、ゼオライトをエチレン吸着剤として使用する際には、ＳｉＯ２とＡｌ２Ｏ３との比（ＳｉＯ２／Ａｌ２Ｏ３）を１０以上１００以下とし、さらに０．０１重量％以上のパラジウムを担持させる必要があり、コスト増が避けられないという不都合がある。 However, when using zeolite as the ethylene adsorbent, the ratio of SiO 2 and Al 2 O 3 to (SiO 2 / Al 2 O 3 ) is 10 or more and 100 or less, further 0.01% or more by weight of palladium There is an inconvenience that an increase in cost is inevitable.
　本発明は、かかる不都合を解消して、安価な材料で青果物の成熟を抑制することができる青果物の成熟抑制材を提供することを目的とする。 The object of the present invention is to provide a fruit and fruit maturity suppressing material that can eliminate such inconvenience and can suppress the maturity of fruit and vegetables with an inexpensive material.
　かかる目的を達成するために、本発明の青果物の成熟抑制材は、トマトの葉の乾燥物と、浄水汚泥又は河川若しくは湖沼に堆積した汚泥が脱水された脱水汚泥が１５０～２００℃の温度で３０分間乾燥され、２４時間自然冷却され、水分量を５％以下とされた後に粉砕された脱水汚泥乾燥物とを含むことを特徴とする。 In order to achieve this object, the fruit and fruit ripening inhibitor of the present invention comprises dried tomato leaves and purified sludge or dehydrated sludge dehydrated from sludge accumulated in rivers or lakes at a temperature of 150 to 200 ° C. A dehydrated sludge dried product that has been dried for 30 minutes, naturally cooled for 24 hours, and pulverized after the water content is reduced to 5% or less.
　本発明者らの検討によれば、草本植物の葉に含まれるタンニンもしくはタンニンと結合した物質又は、茎に含まれるリグニンもしくはリグニンと結合した物質により、前記青果物が放出するエチレンを吸収し、或いは前記青果物のエチレンの放出自体を抑制することができ、前記草本植物の葉として、トマトの葉の乾燥物を用いることができる。 According to the study by the present inventors, tannin contained in the leaves of a herbaceous plant or a substance combined with tannin, or lignin contained in a stem or a substance combined with lignin absorbs ethylene released by the fruits or vegetables, or The release of ethylene in the fruits and vegetables itself can be suppressed, and dried tomato leaves can be used as the leaves of the herbaceous plants.
　従って、前記青果物の成熟抑制材として、トマトの葉の乾燥物を前記青果物の付近に配設することにより、該青果物の成熟を抑制することができる。また、前記トマトの葉の乾燥物は、前記青果物としてのトマトを収穫後の廃棄物を利用することができるので、安価である。 Therefore, maturation of the fruits and vegetables can be suppressed by arranging a dried product of tomato leaves in the vicinity of the fruits and vegetables as a material for inhibiting the fruits and vegetables from ripening. In addition, the dried tomato leaves are inexpensive because wastes after harvesting the tomatoes as the fruits and vegetables can be used.
　また、前記草本植物の葉又は茎は、硫化物又は窒化物からなる悪臭物質を含んでいる。従って、前記草本植物の葉又は茎を青果物の成熟抑制材として前記青果物の付近に配設すると、前記悪臭物質の悪臭により該青果物の商品価値を損なうことがある。 Also, the leaves or stems of the herbaceous plants contain malodorous substances made of sulfide or nitride. Therefore, when the leaves or stems of the herbaceous plants are disposed in the vicinity of the fruits or vegetables as a material for suppressing the maturity of fruits or vegetables, the product value of the fruits or vegetables may be impaired due to the malodor of the malodorous substance.
　そこで、本発明の青果物の成熟抑制材は、前記トマトの葉の乾燥物に加えて、前記脱水汚泥乾燥物を含むことにより、エチレンを吸収又はその放出を抑制する効果と同時に、前記悪臭物質を吸収することができる。前記脱水汚泥乾燥物としては、株式会社エコハイテクコーポレーション製エコソイル（商品名）を用いることができる。また、前記脱水汚泥乾燥物は、特許第５０７０６３６号公報に詳細な記載がある。 Therefore, the fruit and fruit ripening inhibitor according to the present invention contains the dehydrated sludge dried product in addition to the dried tomato leaf dried product, so that the malodorous substance can be absorbed simultaneously with the effect of suppressing or releasing ethylene. Can be absorbed. As the dehydrated sludge dried product, Eco Soil (trade name) manufactured by Eco High-Tech Corporation can be used. The dehydrated sludge dried product is described in detail in Japanese Patent No. 5070636.
　また、本発明の青果物の成熟抑制材は、トマトの茎の乾燥物を含むことが好ましい。上述のように、草本植物の茎に含まれるリグニンもしくはリグニンと結合した物質によっても、前記青果物が放出するエチレンを吸収し、或いは前記青果物のエチレンの放出自体を抑制することができる。従って、本発明の青果物の成熟抑制材は、トマトの葉の乾燥物に加えてトマトの茎の乾燥物を含むことにより、さらに前記青果物が放出するエチレンを吸収し、或いは前記青果物のエチレンの放出自体を抑制する効果を得ることができる。 Moreover, it is preferable that the fruit and fruit ripening suppression material of the present invention contains a dried product of tomato stems. As described above, lignin contained in the stem of a herbaceous plant or a substance combined with lignin can also absorb ethylene released by the fruits or vegetables, or suppress the ethylene release itself of the fruits and vegetables. Therefore, the fruit and fruit maturation suppressing material of the present invention includes the dried tomato stem in addition to the dried tomato leaves, thereby further absorbing ethylene released by the fruits and vegetables or releasing the ethylene of the fruits and vegetables. The effect which suppresses itself can be acquired.
　また、本発明の青果物の成熟抑制材は、粉末にして用いることもできる。本発明の青果物の成熟抑制材は、粉末にすることにより、シート又は成形体等に容易に混合することができる。 Also, the fruit and fruit ripening inhibitor of the present invention can be used in powder form. The fruit and fruit ripening suppression material of the present invention can be easily mixed into a sheet or a molded body by making it into powder.

　次に、添付の図面を参照しながら本発明の実施の形態についてさらに詳しく説明する。 Next, embodiments of the present invention will be described in more detail with reference to the accompanying drawings.
　本実施形態の青果物の成熟抑制材は、トマトの葉の乾燥物と、浄水汚泥又は河川若しくは湖沼に堆積した汚泥が脱水された脱水汚泥が１５０～２００℃の温度で３０分間乾燥され、２４時間自然冷却され、水分量を５％以下とされた後に粉砕された脱水汚泥乾燥物とを含み、さらにトマトの茎の乾燥物を含んでいてもよい。 The fruit and fruit maturity suppression material of this embodiment is a dried tomato leaf and dewatered sludge from which purified water sludge or sludge accumulated in rivers or lakes has been dehydrated is dried at a temperature of 150 to 200 ° C. for 30 minutes for 24 hours. It may be naturally cooled and dried with dehydrated sludge that has been crushed after the water content is reduced to 5% or less, and may further include dried tomato stem.
　前記脱水汚泥乾燥物としては、株式会社エコハイテクコーポレーション製エコソイル（商品名）を用いることができる。前記脱水汚泥乾燥物は、水溶性の悪臭物質を効果的に吸収することができ、トマトの葉又は茎の乾燥物に含まれる硫化物又は窒化物からなる悪臭物質を吸収することができる。 As the dehydrated sludge dried product, Eco-Soil (trade name) manufactured by Eco High-Tech Corporation can be used. The dried dehydrated sludge can effectively absorb water-soluble malodorous substances and can absorb malodorous substances composed of sulfides or nitrides contained in dried tomato leaves or stems.
　また、本実施形態の青果物の成熟抑制材は、粉末として用いてもよい。この場合、本実施形態の青果物の成熟抑制材は、例えば、パルプモールドの果物トレイ等に配合して用いることができる。 Moreover, you may use the maturity suppression material of fruit and vegetables of this embodiment as a powder. In this case, the fruit and fruit ripening inhibitor of the present embodiment can be used, for example, by blending it into a pulp mold fruit tray or the like.
　また、本実施形態の青果物の成熟抑制材は、タンニンを含む草本植物の葉であればどのような草本植物の葉でもよく、リグニンを含む草本植物の茎であればどのような草本植物の茎でもよい。葉がタンニンを含むか又は、茎がリグニンを含む草本植物として、前記トマトの他、例えば、トマト、ナス、ジャガイモ、トウモロコシ、シソ等の草本植物を挙げることができる。また、前記草本植物の葉又は茎は、該草本植物の一部であってリグニン又はタンニンを含むものであればよく、例えば、トウモロコシの莢等も含む。 Further, the fruit and fruit maturation suppressing material of the present embodiment may be any herbaceous plant leaf as long as it is a herbaceous plant leaf containing tannin, and any herbaceous plant stem as long as it is a stem of a herbaceous plant containing lignin. But you can. Examples of herbaceous plants whose leaves contain tannins or whose stems contain lignin include herbaceous plants such as tomatoes, eggplants, potatoes, corns and perillas in addition to the tomatoes. Further, the leaves or stems of the herbaceous plants may be any part of the herbaceous plants and contain lignin or tannin, and include, for example, corn straw.
　本実施形態の青果物の成熟抑制材は、前記草本植物の葉又は茎が未乾燥物であってもよいが、この場合には前記草本植物の葉又は茎が水分を含んでいる。そこで、本実施形態の青果物の成熟抑制材は、前記草本植物の葉又は茎が未乾燥物である場合には、パルプ等の吸湿材を含むことが好ましい。 In the fruit and fruit maturity suppression material of this embodiment, the leaves or stems of the herbaceous plants may be undried, but in this case, the leaves or stems of the herbaceous plants contain moisture. Therefore, it is preferable that the fruit and fruit maturity-suppressing material of this embodiment includes a moisture-absorbing material such as pulp when the leaves or stems of the herbaceous plants are undried.
　本実施形態の青果物の成熟抑制材は、前記吸湿材を含むことにより、前記未乾燥物の水分を吸収することができる。このとき、本実施形態の青果物の成熟抑制材は、例えば、シート状として用いるようにしてもよく、流通段階においてはコンテナの底に敷き詰めるような使用形態が考えられる。 The fruit and fruit ripening suppression material of this embodiment can absorb the moisture of the undried material by including the hygroscopic material. At this time, the fruit and fruit ripening suppression material of the present embodiment may be used, for example, in the form of a sheet, and in the distribution stage, a usage form in which it is spread on the bottom of the container is conceivable.
　次に、本実施形態の青果物の成熟抑制材をトマトの付近に配設したときのトマトの糖度の経時変化を測定した。 Next, the change over time in the sugar content of the tomato was measured when the fruit and fruit ripening inhibitor of this embodiment was placed near the tomato.
　前記測定では、まず、収穫後の未成熟のトマトを２個（約４００ｇ）ずつ、７枚の２重チャック付きポリエチレン袋（２２０ｍｍ×１８０ｍｍ）に入れて密封し、３日後に開封した。各ポリエチレン袋のうち、ポリエチレン袋Ａにはトマト以外何も入れず、ポリエチレン袋Ｂにはゼオライト５ｇを入れ、ポリエチレン袋Ｃにはトマトの茎の乾燥物３ｇを入れ、ポリエチレン袋Ｄにはトマトの茎の乾燥物５ｇを入れ、ポリエチレン袋Ｅにはトマトの葉の乾燥物３ｇと前記脱水汚泥乾燥物３ｇとを入れ、ポリエチレン袋Ｆにはトマトの茎の乾燥物５ｇとトマトの葉の乾燥物５ｇと前記脱水汚泥乾燥物３ｇとを入れ、ポリエチレン袋Ｇにはトマトの茎の乾燥物４ｇとトマトの葉の乾燥物８ｇと前記脱水汚泥乾燥物３ｇとを入れた。 In the measurement, first, two immature tomatoes after harvesting (about 400 g) were placed in seven double-chucked polyethylene bags (220 mm × 180 mm), sealed, and opened three days later. Among each polyethylene bag, nothing other than tomato is put in polyethylene bag A, 5 g of zeolite is put in polyethylene bag B, 3 g of dried tomato stem is put in polyethylene bag C, and tomato is put in polyethylene bag D. 5 g of dried stem material, 3 g of dried tomato leaf and 3 g of the dehydrated sludge dried product are put in polyethylene bag E, and 5 g of dried tomato stem product and dried tomato leaf are put in polyethylene bag F. 5 g and 3 g of the dehydrated sludge dried product were placed. In the polyethylene bag G, 4 g of dried tomato stems, 8 g of tomato leaf dried product, and 3 g of the dehydrated sludge dried product were placed.
　開封直後、１日後、３日後、６日後、７日後に、各ポリエチレン袋に入れたトマトの糖度を糖度計（株式会社アタゴ製、商品名：ＰＡＬ－１）により測定し、成熟状況を確認した。結果を図１に示す。 Immediately after opening, 1 day, 3 days, 6 days, and 7 days later, the sugar content of the tomatoes contained in each polyethylene bag was measured with a sugar content meter (trade name: PAL-1 manufactured by Atago Co., Ltd.) to confirm the maturity status. . The results are shown in FIG.
　図１から、トマト以外何も入れなかったポリエチレン袋Ａでは密封中に糖度の最高値に達し、その後は急速に糖度が低下したことがわかる。また、ポリエチレン袋Ｃ～Ｇでは、トマトの葉又は茎の量を変えることにより、糖度の上昇又は下降を緩やかにすることができ、特に茎の量の多いポリエチレン袋Ｄの場合には糖度のピークを迎える時期を遅らせ、その後成熟に向かわせることができることがわかる。 From FIG. 1, it can be seen that in the polyethylene bag A in which nothing other than tomatoes was put, the maximum sugar content was reached during sealing, and then the sugar content rapidly decreased. In addition, in the polyethylene bags C to G, the increase or decrease in sugar content can be moderated by changing the amount of tomato leaves or stems. Especially in the case of the polyethylene bag D having a large amount of stems, the sugar content peak It can be seen that it is possible to delay the time of greeting and then move to maturity.
　従って、本実施形態の青果物の成熟抑制材によれば、エチレンの吸収又は青果物自体のエチレンの放出を抑制することにより、成熟のタイミングを制御することができることが明らかである。この結果、例えば、青果物の流通期間又は店頭陳列期間を延長したり、店頭に陳列される時期を遅らせることができる。 Therefore, according to the fruit and fruit ripening inhibitor of this embodiment, it is apparent that the timing of ripening can be controlled by suppressing ethylene absorption or ethylene release from the fruit and vegetables themselves. As a result, for example, it is possible to extend the distribution period or store display period of fruits and vegetables, or to delay the time of display at the store.
　次に、前記脱水汚泥乾燥物の作用効果について説明する。 Next, the function and effect of the dehydrated sludge dried product will be described.
　まず、内容積５００ミリリットルの密閉容器に、１００ｐｐｍの濃度のアンモニアガスと、脱水汚泥乾燥物１ｇ（株式会社エコハイテクコーポレーション製、商品名：エコソイル）とを投入し、ガスクロマトグラフィーにより該密閉容器中のアンモニアガスの残留濃度を経時的に測定した。結果を図２に示す。 First, 100 ppm of ammonia gas and 1 g of dehydrated sludge dried product (trade name: Ecosoil, manufactured by Eco High-Tech Corporation) are put into a sealed container having an internal volume of 500 ml, and the gas is chromatographed in the sealed container. The residual concentration of ammonia gas was measured over time. The results are shown in FIG.
　図２から、前記密閉容器中のアンモニアガスの残留濃度は測定開始後１０分で急激に低下し、６０分後にはほぼゼロになっており、前記脱水汚泥乾燥物は優れたアンモニア吸着能を備えていることが明らかである。 From FIG. 2, the residual concentration of ammonia gas in the sealed container rapidly decreases 10 minutes after the start of measurement, and becomes almost zero after 60 minutes. The dehydrated sludge dry matter has an excellent ammonia adsorption capacity. It is clear that
　次に、内容積１４０リットルの密閉容器に、２．０ｐｐｍの濃度の硫化水素ガスと、脱水汚泥乾燥物２０ｇ（株式会社エコハイテクコーポレーション製、商品名：エコソイル）とを投入し、ガス腐食試験機（スガ試験機株式会社製、型式：ＧＳ－ＵＶ）により該密閉容器中の硫化水素ガスの残留濃度を経時的に測定した。結果を図３に示す。 Next, a hydrogen sulfide gas having a concentration of 2.0 ppm and 20 g of dried dehydrated sludge (trade name: Ecosoil, manufactured by Eco High-Tech Corporation) are charged into a sealed container having an internal volume of 140 liters, and a gas corrosion tester The residual concentration of the hydrogen sulfide gas in the sealed container was measured over time by (Suga Test Instruments Co., Ltd., model: GS-UV). The results are shown in FIG.
　図３から、前記密閉容器中の硫化水素ガスの残留濃度は測定開始から２４０分後に０．０７ｐｐｍとほぼ１／３になっており、前記脱水汚泥乾燥物は優れた硫化水素吸着能を備えていることが明らかである。 From FIG. 3, the residual concentration of hydrogen sulfide gas in the sealed container is approximately 1/3, 0.07 ppm after 240 minutes from the start of measurement, and the dehydrated sludge dry matter has excellent hydrogen sulfide adsorption ability. It is clear that
　図２、図３から、前記脱水汚泥乾燥物は、アンモニアに代表される窒化物や、硫化水素に代表される硫化物について、優れた吸着能を備えることが明らかである。従って、本実施形態の青果物の成熟抑制材は、前記脱水汚泥乾燥物を含むことにより、前記トマトの葉又は茎に含まれる窒化物や硫化物等の悪臭物質を吸収することができ、該青果物の商品価値を高めることができる。 2 and 3, it is clear that the dehydrated sludge dried product has an excellent adsorption capacity for nitrides represented by ammonia and sulfides represented by hydrogen sulfide. Therefore, the fruit and fruit ripening suppression material of this embodiment can absorb malodorous substances such as nitrides and sulfides contained in the tomato leaves or stems by including the dehydrated sludge dry matter, and the fruits and vegetables. Can increase the product value.
