During the storage and transportation of bananas, banana ethylene absorbers play a vital role. It can effectively absorb the ethylene gas produced by bananas, slow down the ripening speed of bananas, and maintain the freshness and quality of bananas. This article will give you a detailed introduction to the implementation standards of banana ethylene absorbers.
Principle and importance of ethylene absorption
Banana produces ethylene during the ripening process, which is a natural plant hormone that accelerates the ripening and decay of bananas. Ethylene absorbers remove ethylene from the environment through adsorption, catalytic decomposition and other principles, thereby delaying the physiological ripening process of bananas and extending their shelf life. The application of this technology is of great significance for the long-distance transportation and long-term storage of bananas, and can reduce losses caused by over-ripening.
Material standards
High-quality banana ethylene absorbers should use safe, environmentally friendly materials with good adsorption properties. Generally speaking, commonly used adsorption materials include activated carbon, alumina, etc. These materials should meet relevant environmental protection standards and do not contain substances that are harmful to the human body and the environment. For example, the specific surface area of activated carbon must be large enough to ensure its efficient adsorption capacity for ethylene; the purity and particle size of alumina must also meet specific requirements to ensure its stability and adsorption effect.
Adsorption performance standards
There are clear indicator requirements for ethylene adsorption performance. First, adsorption efficiency is a key indicator, that is, the ratio of the amount of ethylene that the absorber can adsorb within a certain period of time to the total amount of ethylene in the environment. Generally speaking, the initial adsorption efficiency of a good ethylene absorber should reach more than 80%. Secondly, it is the adsorption capacity, that is, the maximum amount of ethylene that the absorber can adsorb before reaching saturation. The larger the adsorption capacity, the longer the service life and the lower the cost of use.
Service life standards
The service life of the banana ethylene absorber is also one of the important criteria for measuring its quality. Under normal conditions of use, the ethylene absorber should be able to continuously and effectively absorb ethylene within a specified period of time. The specific service life will vary depending on the use environment and conditions. For example, in a high temperature and high humidity environment, the generation and absorption rate of ethylene will be accelerated, and the service life of the absorber may be shortened accordingly. Generally speaking, the service life of a high-quality ethylene absorber should be no less than 3 months.
Testing and certification standards
In order to ensure that the quality of banana ethylene absorbers meets the requirements, strict quality testing and relevant certification are required. The testing items include the physical and chemical properties of the materials, adsorption performance, safety and other aspects. At the same time, the products should also comply with relevant international standards and industry standards, such as ISO standards, national standards, etc., to avoid trade barriers caused by inconsistent standards.
Understanding the implementation standards of banana ethylene absorbers is of great significance for selecting suitable products and ensuring the quality and safety of bananas. Only products that meet the standards can truly provide reliable support for the storage and transportation of bananas.
