In the fruit and vegetable preservation industry, how to effectively reduce the loss rate of fruits and vegetables during transportation and storage, and improve the added value of products has always been a major challenge faced by agriculture and food industry. With the development of technology, a new type of material called nuclear pore membrane provides a new solution to this problem with its unique physical properties and preservation effect.
Innovative characteristics of nuclear pore membrane
Nuclear pore membrane is a special type of microporous membrane made by nuclear irradiation and chemical etching techniques, with 600000 to 1 million small pores per square centimeter. These micropores have the characteristic of being breathable and impermeable, providing unique advantages for the preservation of fruits and vegetables.
1. Breathable and impermeable: The nuclear pore membrane allows gas exchange while preventing water infiltration, helping to maintain humidity balance inside the packaging and reducing transpiration of fruits and vegetables.
2. Unidirectional gas exchange: The conical pores on the nuclear pore membrane have unidirectionality, making it easy for gases to escape but difficult for gases to enter, reducing the impact of external environmental gases on fruits and vegetables, and effectively controlling their respiration.
3. Microbial barrier: Nuclear pore membrane can block dust and microorganisms, maintain the cleanliness of fruit and vegetable appearance, and reduce decay.
The preservation effect of nuclear pore membrane
The experimental results show that fruits, vegetables, or fresh aquatic products stored in a nuclear pore membrane spontaneous controlled atmosphere preservation box have a shelf life and storage period that is 3 to 5 times longer than those stored in a regular preservation box under the same conditions. This significant effect makes nuclear pore membrane technology have great potential for application in the field of fruit and vegetable preservation.
Comparison between nuclear pore membrane and traditional preservation methods
Compared with traditional methods such as chemical preservation and freezing preservation, nuclear porous film, as a pure physical preservation technology, does not require the addition of any chemicals and is more environmentally friendly and safe. It achieves natural preservation of fruits and vegetables by controlling their respiration and transpiration, as well as blocking microorganisms, making it a green and healthy way of preservation.
The application prospects of nuclear pore membrane
The nuclear pore membrane technology is not only suitable for the preservation of fruits and vegetables, but can also be extended to the storage and transportation preservation of other foods such as meat and seafood. With the increasing attention to food safety and health, nuclear porous membrane technology is expected to play a greater role in the future preservation industry due to its environmentally friendly and efficient characteristics.
The nuclear pore membrane provides a new solution for the transportation and storage of fruits, vegetables, and other foods due to its unique physical properties and significant preservation effect. With the further development and application of technology, nuclear porous membranes are expected to play a greater role in the preservation industry, contributing to the increase in added value and international competitiveness of agricultural products.
