[0002] Fruits and vegetables are an indispensable part of people's daily diet, rich in vitamins, minerals, dietary fiber, and other nutrients, playing a vital role in human health. However, after harvesting, fruits and vegetables remain living organisms, undergoing physiological metabolic processes such as respiration and transpiration. They are also susceptible to microbial contamination and mechanical damage, leading to quality decline, spoilage, and shortened shelf life, resulting in significant economic losses and resource waste. Therefore, adopting effective preservation technologies to extend the shelf life of fruits and vegetables and maintain their quality and nutritional components is of paramount importance for meeting consumer demand, improving the economic efficiency of the fruit and vegetable industry, and ensuring an effective supply of agricultural products. Since the transportation time of fruits and vegetables in containers is often long, this invention specifically designs a preservation bag for containerized fruit and vegetable transportation, which can automatically and sequentially preserve the freshness.

[0022] like Figure 1 , Figure 2As shown, this utility model provides a preservation bag for containerized fruit and vegetable transportation, comprising a main body 100, which includes an upper bag body 11 and a middle bag body 12 from top to bottom. One side of the upper bag body 11 and the middle bag body 12 is a waterproof and breathable membrane 15. The upper bag body 11 contains a desiccant, and the middle bag body 12 contains 1-methylcyclopropene powder. A slow-release channel 14 is provided between the upper bag body 11 and the middle bag body 12. After the desiccant absorbs water, the moisture enters the middle bag body 12 from the upper bag body 11 through the slow-release channel 14. This utility model first absorbs moisture in the container using a desiccant and cleverly collects the moisture, using gravity to transfer it to the lower bag body. This triggers the preservative in the lower bag body to automatically release preservative gas, which enters the container through the waterproof and breathable membrane 15 for preservation, making it very convenient. 1-Methylcyclopropene (1-MCP) is a novel ethylene inhibitor that preferentially binds to ethylene receptors in fruit and vegetable cells, thereby blocking the normal binding and signal transduction of ethylene to these receptors. This inhibits a series of ethylene-induced physiological and biochemical reactions, significantly delaying the ripening and senescence process of fruits and vegetables. Compared with traditional preservation methods, 1-MCP offers advantages such as high efficiency, specificity, safety, and wide applicability.

[0023] Furthermore, the preservation bag provided by this utility model, which can be used for containerized fruit and vegetable transportation, comprises, from top to bottom, an upper bag body 11, a middle bag body 12, and a lower bag body 13. One side of each of the upper bag body 11, middle bag body 12, and lower bag body 13 is a waterproof and breathable membrane 15. The lower bag body 13 contains slow-release chlorine dioxide gel powder, and slow-release channels 14 are also provided between the middle bag body 12 and the lower bag body 13. Chlorine dioxide is a highly efficient, broad-spectrum, and safe bactericide with strong oxidizing power. It can rapidly penetrate the cell walls and cell membranes of microorganisms, destroying their enzyme systems and protein structures, thereby effectively killing bacteria, viruses, fungi, and other microorganisms. In this utility model, the upper bag body 11, middle bag body 12, and lower bag body 13 are all separate and relatively independent bag bodies.

[0024] Furthermore, in the preservation bag for containerized fruit and vegetable transportation provided by this utility model, multiple slow-release channels 14 are provided, with adjacent slow-release channels 14 spaced apart. Furthermore, in the preservation bag for containerized fruit and vegetable transportation provided by this utility model, the aperture of the slow-release channel 14 between the upper bag body 11 and the middle bag body 12 is larger than the aperture of the slow-release channel 14 between the middle bag body 12 and the lower bag body 13. Moisture enters the lower bag body 13 relatively slowly. Furthermore, in the preservation bag for containerized fruit and vegetable transportation provided by this utility model, the aperture of the slow-release channel 14 between the upper bag body 11 and the middle bag body 12 is 2mm, and the aperture of the slow-release channel 14 between the middle bag body 12 and the lower bag body 13 is 1mm. Furthermore, in the preservation bag for containerized fruit and vegetable transportation provided by this utility model, the length of the slow-release channel 14 is 0.6-1cm. Furthermore, the preservation bag provided by this utility model, which can be used for containerized fruit and vegetable transportation, has a 4mm interval between adjacent slow-release channels 14 between the upper bag body 11 and the middle bag body 12, and a 4mm interval between adjacent slow-release channels 14 between the middle bag body 12 and the lower bag body 13. By controlling the number and size of the slow-release channels 14, the rate at which moisture is fed into the lower bag body can be controlled.

[0025] Furthermore, the preservation bag provided by this utility model, which can be used for containerized fruit and vegetable transportation, has an adhesive layer on the back side of the main body 100 of the preservation bag, and a release paper is provided on the adhesive layer. This allows for easy pasting by lifting the release paper, facilitating the direct installation of the preservation bag inside the container.

[0026] Furthermore, the preservation bag provided by this utility model, which can be used for containerized fruit and vegetable transportation, also includes a breathable fiber layer on the waterproof and breathable membrane 15. Specifically, in the preservation bag provided by this utility model for containerized fruit and vegetable transportation, the desiccant is calcium chloride granules, the main body 100 of the preservation bag is formed by hot pressing the waterproof and breathable membrane 15 and the transparent membrane 16 together, and the partition between different bag bodies is also formed by hot pressing. The breathable fiber layer is non-woven fabric, the waterproof and breathable membrane 15 is a polyethylene composite film, and the transparent membrane 16 is a polyethylene terephthalate and polyethylene composite film. This utility model releases preservation gas sequentially without any external force, making it extremely simple to use and inexpensive.

[0027] In use, this product involves peeling off the release paper from the transparent film 16 and attaching the adhesive layer (double-sided tape) to the inside of the fruit and vegetable transport container or packaging box, with the upper bag 11 positioned at the top. During transport, the water-absorbing desiccant particles in the upper bag 11 absorb water to form an aqueous solution. This solution enters the middle bag 12 through the slow-release channels 14 in the heat-pressed section, releasing 1-methylcyclopropene gas. Subsequently, the aqueous solution enters the lower bag 13, releasing chlorine dioxide gas. This invention achieves humidity control during transport without external force and relies solely on gravity to achieve the sequential release of 1-methylcyclopropene and chlorine dioxide gases, preventing simultaneous release of the two gases and subsequent oxidation-reduction reaction and inactivation. This improves the preservation time of fruits and vegetables and simplifies the usage process.

[0028] In summary, this invention utilizes the water-absorbing desiccant particles in the upper bag to absorb water, forming an aqueous solution. This solution then enters the middle bag through the slow-release channels in the hot-pressing section, releasing 1-methylcyclopropene gas. Subsequently, the aqueous solution enters the lower bag, releasing chlorine dioxide gas. This invention achieves humidity control during transportation without external force. Furthermore, it relies solely on gravity to ensure the sequential release of 1-methylcyclopropene and chlorine dioxide gases, preventing simultaneous release and redox reactions that could lead to inactivation. This improves the preservation time of fruits and vegetables and simplifies the usage process.

[0029] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
