ている。It is known that when fruits and vegetables begin to ripen after ripening, called climatic, the concentration of ethylene gas inside the fruits and vegetables increases rapidly. For example, "Agricultural Products Distribution Technology Research Bulletin" published by the Agricultural Products Distribution Technology Research Group, Vol. 5, No. 12 (December 1982)
On page 55, the ethylene gas concentration before the climatilic of avocado is 0.041)I)m, after the start of the climatilic is 0.75 ppm, the concentration of ethylene gas before the climatilic of banana is 0.0, lppm, and the concentration of ethylene gas is 1 after the start of the climatilic.
．． 5 ppm, 0.
041) I)m, 3.0 pp after starting climatric
It has been reported that O.m, before climatic licking of tomatoes is 0.08 ppm, and after the start of climatic licking is O8 ppm.
このようなエチレンガス濃度の急激な上昇を、反応試薬

、この方法では、後述する比較例から明らかなように、
１００ ｐｐｍ以上のエチレンガス濃度を判定すること
が限界であって、上述したクリマチリックの開始を検知
することはできなかった。An attempt to easily detect such a rapid increase in ethylene gas concentration using a reaction reagent and thereby determine the ripeness of fruits and vegetables was introduced in, for example, Japanese Patent Laid-Open No. 58-52561. ing. In this method, the ripeness of fruits and vegetables is determined by pasting or enclosing a detection paper in which a reaction reagent has been impregnated on the surface of the fruit or vegetables. As is clear from the example,
The limit was to determine an ethylene gas concentration of 100 ppm or more, and it was not possible to detect the onset of climatics described above.
また、同様の試みには、北用式ガス検知管が知られてい

されているように、数百ＣＣの空気をポンプを用いて流

である。In addition, a similar attempt has been made to the Kita-type gas detection tube, which, as pointed out in Japanese Patent Application Laid-open No. 58-52561, uses a pump to flow several hundred CC of air. However, it is not easy to do so, and it is virtually impossible to continuously detect gases generated from the skin of growing fruits and vegetables.
そこで、本発明は、Ｉ Ｑ、 Ｏｐｐｍ以下、例え＆イ
１．Ｏｐｐｍのエチレンガス濃度を検知すること力を可
肯眩で、しかも簡便にその検知が連続的（経時的）に可

る。Therefore, the present invention provides IQ, Oppm or less, for example &I1. To provide a method for determining the quality of edible fruits and vegetables that can detect the concentration of ethylene gas in Oppm in a bright and easy way and continuously (over time).

とにより、青果物の熟度を判定することを特徴とする青
果物の品質判定方法である。That is, the present invention provides a package in which a particulate ethylene detection agent coated on the surface of an inorganic or organic particulate carrier with a reagent that reacts with ethylene gas to form a color is attached to the surface of fruits and vegetables, or is used to store fruits and vegetables. This is a method for determining the quality of fruits and vegetables, which is characterized in that the degree of ripeness of fruits and vegetables is determined by placing the present invention in an atmosphere and detecting ethylene gas generated from the skin of fruits and vegetables over time.

ウ土、軽石、シリカゲル、アルミナ、陶器や出器の破砕
品などがある。In the present invention, the inorganic or organic particulate carrier can be used as long as it is resistant to acids and alkalis and has a granular shape, but it is more preferable if it is porous and has adsorption properties. Examples of such porous granular carriers include diatomaceous earth, pumice, silica gel, alumina, and crushed pieces of pottery and pottery.

）が低下して。Further, the particle size of this granular carrier is preferably 60 to 80 mesh, but any range of 10 to 150 mesh can be used. However, if it is less than 10 meshes,
Although the void space required for the diffusion of ethylene gas is sufficient, the contact area between this gas and the reagent (approximately equal to the surface area of the support) is reduced.
検知感度が低下し、１５０メツシュ以上では空隙率が低
下してエチレンガスの拡散が妨げられ、いずれの場合も
検知感度の低下が生じる。Detection sensitivity decreases, and if the mesh is 150 or more, the porosity decreases and diffusion of ethylene gas is hindered, and in either case, detection sensitivity decreases.

応する際の反応式は以下の通りである。Further, as a reagent that undergoes a color reaction with ethylene gas, an acidic aqueous solution of ammonium molybdate containing a palladium sulfate catalyst can be used, and in order to make this an acidic aqueous solution, it is preferable to mix it with concentrated sulfuric acid. The reaction formula when this reagent undergoes a color reaction with ethylene gas is as follows.

3Mo03-751 (20 (Ammonium Molybdate) (Molybdenum Blue) Note that ammonium molybdate is white and molybdenum blue is blue, but when it absorbs moisture due to residual sulfate radicals in the reagent, it becomes inactive and contaminates the surface of fruits and vegetables. This contamination can be prevented by coating the carrier surface.
