Recently, media reports have reported that the current fruit is overcrowded by drugs. The hardest hit areas involve mango, watermelon, banana and other summer seasonal fruits, which makes consumers feel anxious when buying fruits. Posts about this aspect are widely spread on the Internet. But consumers don't have to worry too much. Fruit ripening is not necessarily unsafe: the use of ethylene, a natural ripening agent, not only does not cause physical harm to consumers, but also keeps fruits well for fruit farmers. Color, taste and shape keep selling well, attracting consumers' attention.
Although ethylene can make fruit mature under your "control", however, the amount of control needs to be very careful, the amount of ethylene is not enough to achieve the purpose of ripening, and the excess will cause the fruit to be too ripe and shorten the market. time. Does the ethylene content meet the requirements? Now, with Witt's portable MFA 9000 gas analyzer, fruit traders can answer this question accurately.
The highlight of the FruitLogistica exhibition in Berlin, Germany, is the German air conditioning technology expert Witt's ethylene analyzer, which measures the ethylene concentration extremely accurately without the reference gas required by other analyzers.
Fruit ripening control
Ethylene is a natural gaseous hormone that can ripen fruits and vegetables. It can enhance the activity of oxidase in fruits, thereby accelerating the conversion of starch into sugar, which accelerates the ripening of fruits and changes the color of the peel.
Fruit traders use this natural phenomenon to control ripening of fruits. For example, a mixture of ethylene and nitrogen mixed with a WITT gas mixer to control the ripening process of bananas is a good example. Adding a mixture of ethylene and nitrogen to the ripening device for storing bananas, the banana begins to mature. Use WITT gas mixer to blow the mixed ethylene and nitrogen mixture into the ripening chamber at high speed, so that the gas-conditioning protective gas in the ripening chamber is evenly mixed, thus ensuring that all bananas are mated and the color changes evenly. .
With MFA9000, the mixing ratio of the gas can be accurately set and controlled as needed to control the speed and degree of fruit ripening. An optional gas analyzer is available to monitor the content of the mixture, either on-line or mobile.
Natural ethylene instead of insecticide
The advent of this new product coincides with the season: Germany and other EU countries are stepping up the implementation of regulations to reduce the use of the pesticide ethylene (Ethephon) for fruit ripening. WITT This gas blender meets the needs of major fruit traders to modify the atmosphere library equipment. The application of this modified atmosphere protects the problem of using chemicals in foods that are not popular with consumers.
No reference gas required
As sales general manager Martin Bender added: "This MFA9000 also has an alarm function and can identify measurement errors." WITT experts also emphasized that the data measured by the analyzer can also be transmitted to the computer via the RS232 interface and controlled entirely by the computer or even the analyzer. Various peripheral devices can be externally connected through the remaining interface. The instrument is easy to operate and almost error-free, as Mr. Bender said: “With just three buttons, anyone can learn to operate.†The instrument's test results are displayed in percentage or ppm (parts per million). On the digital display.
