" lime mango " Initiate and pay close attention to " profit of ethylene " Use and demand the norm urgently
News pegging: According to Beijing Times, the fruit retailer near Beijing Daxing District Xihongmen adds " profit of ethylene " with the quick lime It is ripe to seal the raw mango medicinal liquid. The related departments of Beijing notify to the media, the potential safety hazard does not exist in the mango accelerating the ripening with lime medicine on the the afternoon of April 1.
Interviewed the expert:
Hao FengTong: Occupational disease of Beijing Chaoyang hospital and poisoning medical head of the department, professor.
Hu XiaoSong: Food science of China Agricultural University and institute's professor of the nutrition project.
Fan ZhiHong: Food institute's nutrition and food security of China Agricultural University are associate professors.
The housewife accelerates the ripening to employ commonly usedly
The method that the retailer who the media recommends while reporting seals the well done mango is, add Sheung Shui in a basin of lime, add about half a bottle of ethylene favourable water pharmaceutical to stir, then pour the lime water on the toilet paper, make " medicine cushion " ,Then sealed and familiar with with these medicine cushion the mango parcel. Among them it is the profit of ethylene that play a role in sealing familiarly.
The principle is not abstruse that this one has accelerated the ripening, we have already used in daily life. For example, after buying back the stiff kiwi fruit, the experienced housewife will put already well done fruits such as kiwi fruit, banana, apple,etc. in the same bag, the kiwi fruit is a little fast ripe.
Why?
The stiff kiwi fruit will be under the already well done apple, drive of banana, fast and ripe, play a driving role apple, banana release one that come out accelerate the ripening gas - -Ethylene.
According to recording, Egyptians planted figs more than 100 years ago, not long after bearing fruits, the fruit grower will mark some holes on the fig tree, say that can let the fruit be bigger, ripe faster. Likewise, Chinese peasant who is planted walnut can cut down the wound at the walnut too after the walnut grows the fruit, let the walnut grow greater. The two are the same principle, people were just regarded as a kind of experience handed down from age to age at that time.
Until 1934, British scientist Gan En separated the existence measured from the ripe apple to ethylene, ethylene is known as one " Plant accelerate the ripening hormone " . Hereafter, ethylene was applied to accelerating the ripening of the fruit and kept fresh extensively gradually - -The fruit grower cut and injured the trunk of the fig tree originally, because the trunk could release ethylene of higher density, it is ripe to accelerate figs.
With scientific development, the artificial synthesis can release the chemical material of ethylene gas - -" profit of ethylene " ,The ethylene profit after diluting will be transformed into ethylene after being absorbed by the fruit plant, it is ripe to promote fruits. The profit of ethylene is generally applied to the fruits and vegetables while accelerating the ripening gradually, in the production of crops such as tomato, apple, cherry, grape, cucumber, pumpkin, pineapple, cotton, coffee, tobacco, wheat,etc., can all see the figure of the profit of ethylene.
