These misconceptions about oranges need to be clarified

Winter is coming, and the right sweet and sour ratio and shelf-stable characteristics make oranges a must-have fruit
for every household in winter.
But recently, some statements have circulated on the Internet, which has confused many people
.
On December 28, the Jiangxi Provincial Market Supervision Bureau issued a special consumption reminder in order to clarify those misunderstandings
about orange consumption.

Oranges are also "positive"? In the online video, the photographer dripped orange juice into the new crown antigen test kit, and the test result was positive
.
Or drop orange juice directly in the detection well, orange juice with a lower pH will destroy the colloidal gold structure, resulting in false positives
for antigen results.
But in fact, the antigen test sample comes from the nasal mucosa, not from the digestive tract
.
Therefore, antigen nucleic acid detection should be strictly operated by instructions, and the results obtained are of reference significance
.
After eating oranges, low-acid orange juice may remain in the digestive tract (oral or pharyngeal mucosa), but it will not affect the nasal mucosal sample, let alone the antigen test results
.

Can salt steamed oranges stop cough? Recently, a variety of "home remedies" to relieve the symptoms of the new crown have spread in the circle of friends, and "salt steamed oranges can relieve cough" is one of
them.
Although ingredients such as hesperidin and noscapine contained in orange peel can be used in cough medicines, the cough suppression effect of salt-steamed oranges varies
from person to person.
In addition, the process of cooking destroys nutrients such as Vc in oranges, and overly concentrated brine can even irritate the airways, causing coughing to worsen
.
It should be remembered that cough is not a disease but a symptom, and the cause of cough should be found and the right medicine should be prescribed, and diet therapy cannot replace the drug treatment of the disease
.

Can orange supplementation Vc prevent new crown? Vitamin C has been found in new crown clinical trials to improve immunity and oxidative damage, so daily intake of moderate amounts of Vc can improve the body's disease resistance
.
Each 100 grams of orange contains about 30-100 mg of Vc, which is higher
than the supplement Vc artifact - lemon rumored on the Internet.
Therefore, moderate consumption of oranges can meet the daily needs of the human body and enhance immunity to the new crown
.
However, it is unrealistic and unscientific to significantly improve immunity and prevent the new crown only by supplementing Vc in large doses
.

It is necessary to remind consumers that the storage of oranges should pay attention to two aspects
.
Oranges have a thick skin and are shelf-stable fruits, and their skin is generally dried and placed in a cool and dry place to store for a long time
.
Single fruits can also be encapsulated with plastic wrap (PE film) for simple modified atmosphere storage, which can inhibit the reproduction of microorganisms and reduce water loss
.

Of course, pervasive mold is the biggest headache
.
Therefore, many orange skins will be preserved by waxing
.
According to the National Standard for Food Safety, Standard for the Use of Food Additives (GB 2760-2014), morpholine fatty acid ester (also known as fruit wax), carnauba wax, etc.
, can be used on the surface of
fresh fruits.
In addition, if moldy oranges are found, they should be picked up and discarded in time to avoid contaminating other oranges
