THEdrinking water it is a precious asset, which is completely lacking in many states around the world. To win the battle against malnutrition and lack of drinking water, scientists they are watching to the past, to be precise to ancient Egypt, when at the time of the pharaohs water was made good and drinkable thanks to the use of some semi. Among the many researches on the subject the one performed stands out from Pennsylvania State University, which investigated this topic in depth to research methods that can purify water in a natural way and therefore make it drinkable for the population.
The plant that produces the purifying seeds is called Moringa oleifera and it grows in the subtropical zone and equatorial of the planet. In particular, the ancients Egyptians used the flour obtained from its seeds to purify water and therefore make it drinkable. American scientists they then analysed the seeds of the plant to understand its virtues and the reason for its function could be hidden in one of the proteins that compose it, which performs a function cationic, i.e. with a positive charge. This protein contains a sort of peptide sequence, capable of cutting through germs, microbes and bacteria like a real knife and therefore killing them, making the water purer.
The function of the protein is associated with the nature of the seeds, which once immersed in water perform a further purifying function, as they lower polluted substances and microbes to the bottom, leaving surface water pure and clean. But the seeds do much more, as they stab the bacteria and unite them into a single membrane, which causes the germs to end up at the bottom of the container, which no longer disturb those who drink the water. In other words the seeds they definitively knock out germs and microbes, with a natural system infinitely refined.
