Opinion:
Some unscrupulous merchants in order to baby vegetables look good, to be able to save for a long time, therefore, will be soaked in formaldehyde, and this solution contains a large number of carcinogens, so the baby vegetables are not edible.
Truth:
Formaldehyde is an organic compound with a peculiarly pungent odor, colorless, irritating to the eyes and nose, and described by the U.S. National Toxicology Program as a "known human carcinogen" in 2011. Therefore, the formaldehyde in the baby vegetables, is an illegal additive, so the regular channels to buy, do not add illegal additives baby vegetables is not carcinogenic.
So what is the toxicity of some illegal formaldehyde-added baby vegetables? In fact, even in the packaging of baby vegetables before dipped in formaldehyde, but formaldehyde is extremely soluble in water and volatile, in transportation, sale, storage, a lot of formaldehyde has been volatilized. After washing, there are a lot of dissolved in water loss, and then after cooking, will also be volatilized by heating.
So, even if it contains formaldehyde baby vegetables, after heavy volatilization, the formaldehyde in it will become very little, to the average person's food is not toxic phenomenon. If you are not sure, you can wash it a few times before eating it.
2, buy fungus "the fresher the better"
Opinion:
A media report "a little girl was sent to the ICU because she ate too long to soak the cold fungus and poisoning", then, the Internet The first thing you need to do is to get a good deal on a new product or service.
Truth:
Experimental studies have shown that fresh fungus contains porphyrin, which is a photosensitive substance, eating it is easy to cause solar dermatitis, rashes and other diseases, and if you eat too much, it will also cause respiratory mucous membrane allergies, which triggered respiratory difficulties. Each person's tolerance of porphyrin is different, once excessive intake will trigger human discomfort.
And, porphyrin this substance is insoluble in water, simple cleaning is not able to remove, you need to dry the fungus, so that the photoreceptor substances will be decomposed, so the fresh fungus must be dried treatment.
The dried fungus, if soaked for too long, will produce a bacterium called Pseudomonas aeruginosa, which produces a fatal toxin called "myrmecolic acid," which can kill up to 50 percent of the population. The mortality rate of this toxin is more than 50%, which is also one of the toxins with the highest mortality rate in bacterial food poisoning. Therefore, the dried fungus can not be soaked for too long, soaked open fungus should be cooked in time.
3, out-of-season garlic moss formaldehyde treatment and then put in cold storage
Opinion:
A video was circulated on the Internet, a few women wearing gloves and plastic jackets, the tips of bundles of garlic moss quickly immersed in milky white liquid. Rumor-mongers claim that garlic moss soaked in formalin is hazardous to human health.
Truth:
The video was filmed after the harvest of garlic moss, the process before storage, used to soak the garlic moss milky white liquid is a preservative emulsion. Garlic moss after fresh treatment, can effectively inhibit the storage period mold, aging.
And the formaldehyde solution should be clarified, formaldehyde preservation is generally for things with high protein content, such as taxidermy, garlic moss if the formaldehyde preservation effect will not be very good.
4, cucumber hormone, will unknowingly become larger
Opinion:
Friends Circle circulated a "cucumber injection of hormones with a bottle" video, video of a man in a melon field, found that the cucumber are hanging "bottle! "
The truth is that the cucumbers have been injected with hormones in the form of a vial, and the cucumbers have been injected with hormones in the form of a vial.
Truth:
First of all, from the cost point of view, this practice is not realistic, because the price of cucumbers is not expensive, each cucumber are hanging so big "bottle", for farmers too much investment.
Secondly, national regulations allow the use of 10 kinds of growth regulators, including gibberellin, cucumbers, generally by dipping, spraying, dipping, etc., and plant hormones are generally low toxicity and volatilization of the fast, the residue is basically not. In addition, the structure and function of plant hormones are different from animal hormones, plant hormones mainly act on plant cells, there is no research to show that its side effects on the human body.
So, for these four kinds of vegetables vegetables, we can eat with complete confidence, do not let the rumors blindfolded.
