There is a great discussion about what best Sharp tablesThe field is those who prefer them from wood and think that plastic is better. In some cases, this may be a matter of taste or comfort. Nevertheless, scientists themselves also join the debate, since each of them has great inconvenience in food security. Wooden are very prone to proliferation of bacteria, while plastic can release hundreds of hundreds Microplastics And the fibers that end in food and can affect our health.
Thus, many scientists are looking for alternatives, such as the one that is just represented by the team of researchers from Research Institute HopkirkHe New Zealand Center for Science of Food Safety and Research And New Zealand Applied Technologies GroupThe field in his case is very special, because to achieve this they created in nature. Specifically in The wings of the cicata and the skin of the shark.
This is usually. Nature is full of inspiration if we know how to look at it. For the production of these cutting tables, the structure of animals was not used. The formation of surfaces that naturally reflect Microbial proliferation. The result is not yet available on the market, but it should not be surprised that it is the basis Cutting tables of the future.
The problem of ordinary cutting boards
Currently cutting boards can be from many materials, although the most common are Plastic and wood. The risk of plastic is more than clear. Wood is dangerous because bacteria can accumulate in their fields. Wood can be treated to reduce its pores. Even in some places, especially at the industrial level, Nepari stainless steel To cut food. However, bacteria can also join each other on these surfaces, forming a kind of layer, known as Biolfilm, This makes them very stable even to disinfectants.
We all saw and even touched the biofilm. Does this slippery layer sound, which sometimes forms in kitchen tissues that does not even go to wash them? You do not see bacteria, logically, but this is a biofilm.
Nature solutions
The authors of the study, which was published for a long time in search of material, with which you can make safer tables. To do this, they drew attention to some animals, known for being able to reflect bacteria and other microorganisms. For example, a case Cicadas and sharks.
If the wings of the first and the skin of a second on a nanometric scale are considered, it is clear that they have a specific texture that prevents the adhesion of bacteria and, of course, is pierced.
These scientists thought that perhaps it was possible mold metals with laser To give your surface this concrete texture. After several tests, they confirmed that this is not just possible. You can also make cutting tables concrete bacteriaCreating specific textures to prevent your union. Thus, they can be avoided, first of all, which are more dangerous to health.
This has not yet been done on a large scale. It will be necessary to conduct more experiments, but the truth is that at the moment it seems to be a good starting point. While these cutting boards are not on the market, we have no choice but to resort to some of the available ones. The reality is that it is difficult to choose between plastic and wood, because the inconvenience of each of them is very important. If you choose wood, try to change it regularly and try to accumulate a lot of moisture in it. In any case, other materials will always be the best option. Until we have metals based on the skin of a shark, glass It can be a good option. Of course, be careful with knives. They can be ignored by rubbing this material.
