This process is significant for preserving food, as it inhibits the growth of spoilage organisms while enhancing flavors and textures in various traditional foods.
Nutrient density: Nutrient density refers to the amount of essential nutrients provided per calorie in a food item, indicating how much nutrition is packed into a given calorie count. Foods that are considered nutrient-dense are typically rich in vitamins, minerals, and other beneficial compounds while being lower in empty calories from added sugars and unhealthy fats. This concept is particularly important when looking at traditional food preservation techniques, as these methods often maintain or enhance the nutrient profile of foods.
Oral traditions: Oral traditions refer to the stories, histories, and cultural knowledge passed down through generations by word of mouth. These traditions often encompass myths, legends, songs, and rituals that hold significant meaning for a community, serving as a vital link between the past and present while preserving cultural identity and knowledge systems.
