Rumor Refutation：Does Watermelon Wrapped in Plastic Wrap and Placed in the Refrigerator Spawn Bacteria More Easily?

 Scientific research papers published in authoritative academic journals and peer reviews have also confirmed that, compared to watermelons wrapped in plastic wrap, those not wrapped show faster microbial growth; changes in appearance, aroma, taste, and texture also occur more rapidly.

In simple terms, watermelons not wrapped in plastic wrap are more prone to becoming unappealing, unpleasant to eat, and spoiling more easily.

What is the purpose of plastic wrap?

Plastic wrap is a thin layer of plastic film that can effectively isolate food from its surroundings (although it does not completely seal off air). It does not have the function of killing bacteria or inhibiting bacterial growth, so after wrapping food in plastic wrap, it still needs to be refrigerated or frozen for preservation.
When used to package food, it can:

  1. Prevent the loss of moisture.
  2. Reduce bacterial contamination from the air and flavor transfer.
  3. Minimize contact between food and the outside air.

How to properly select and use plastic wrap to protect fruits?

Most plastic wraps available on the market are safe for normal use (primarily made of Polyvinyl Chloride (PVC), Polyethylene (PE), and Polyvinylidene Chloride (PVDC)).

Finally, we remind you again that any leftover watermelon during summer can be stored in the refrigerator with plastic wrap.
However, it is recommended to consume it within 12 hours and no later than 24 hours to avoid the proliferation of bacteria that may pose a threat to health.

Rumor Refutation: Pay Attention to Dental Health NO.1

  Rumor 1: Orthodontic treatment should be done as early as possible, and the earlier the correction, the better the result. ✔/✗: Partially correct, partially incorrect. Orthodontic treatment should indeed be initiated early, but not necessarily as soon as possible. The period from 7 to 12 years old is a crucial stage for early intervention, during which the growth potential of teeth and jaws can be fully utilized to correct dental and jaw malformations. Therefore, all children should undergo an initial consultation with an orthodontist at age 7 to check for dental anomalies such as impacted teeth, supernumerary teeth, and congenitally missing teeth. For certain specific malformations, such as skeletal Class III malocclusion (anterior crossbite) and mesio-inclined lingual occlusion, orthodontic treatment may begin as early as age 5. However, in clinical practice, it is often observed that some 2-year-olds undergo orthodontic treatment, which falls into the category...

Rumor Refutation:Can an ordinary mask turned into an N95 mask by tying a knot?

  1.Wearing a medical mask with knots tied improves its sealing performance Following the method demonstrated in the video, the sealing performance of a common surgical mask can indeed be improved, preventing viruses from reaching the respiratory tract through gaps on both sides. Before conducting science popularization and promotion, the US CDC publicly released relevant experimental reports around February 2021. The report indicated that tying knots and then wearing the mask can enhance filtration efficiency. 2.Knots don't turn it into an N95; there are significant differences in all aspects. The differences between the medical surgical masks we usually use and N95 masks manifest in many ways: In terms of filtration efficiency: N95 masks are one of the nine particulate respirators certified by the National Institute for Occupational Safety and Health (NIOSH). The "N" stands for "not resistant to oil," and "95" indicates that the filtration effic...

Rumor Refutation: Pay Attention to Dental Health NO.2

  Rumor 1: There are many complications associated with orthodontic treatment, so it should be avoided if possible. ✔/✗: Incorrect statement. In reality, the sequelae associated with orthodontic treatment are far fewer than people often perceive. When appropriate appliances and forces are utilized for correction, and patients comply well with treatment, these supposed sequelae can be completely avoided. In the case of adult orthodontic treatment, there are indeed some special considerations. For instance, adult patients may already have periodontal disease or gingival recession, and in cases of malalignment, there may be insufficient bony support between teeth, which can lead to the emergence of "black triangle" spaces after correction. This phenomenon is relatively common in adult orthodontic treatment, but it is not a direct consequence of the treatment itself; rather, it is a natural occurrence during the improvement of tooth alignment. To minimize the oc...
