Salting was another common practice; salt draws moisture out of food, creating an environment inhospitable to bacteria that cause spoilage.
Drying, or dehydration, was also utilized, as removing moisture from food inhibits the growth of microorganisms and enzymes that could lead to decay.
Fermentation, a process that relies on the action of microorganisms to convert sugars into alcohol or acids, was another method that not only preserved food but also enhanced its flavor and nutritional value.
Pickling, similar to fermentation, involved immersing food in a solution of vinegar or brine, which would prevent spoilage. Additionally, sailors would store food in oil or fat, which, being devoid of water, served as a barrier to bacteria and helped preserve the food.
Boiling food and then sealing it in airtight containers was a precursor to canning and helped to keep food edible for extended periods. Beans and rice, which are less perishable, were also staples on long voyages due to their long shelf life and nutritional content. These grains could be stored dry and then cooked as needed. The use of alcohol, such as brandy or rum, to preserve fruits was another technique, as the high alcohol content would prevent the growth of bacteria.
These methods were not only practical but also reflected the available resources and the need for food that could withstand the harsh conditions at sea. The preservation techniques evolved over time, becoming more sophisticated as sailors and explorers learned from experience and shared knowledge across cultures and continents.

The development of these techniques was crucial for the success of long maritime expeditions and had a significant impact on the exploration and trade that shaped the modern world.
