La sal como conservante

The video explains how microorganisms thrive in water-rich foods and how the Egyptians discovered salt's preservative properties during mummification. Salt, mainly composed of sodium chloride, prevents bacterial growth by extracting water from cells through osmosis. To effectively preserve food, its water content must be reduced significantly. This method has been used for centuries and remains a key food preservation technique today.
