During the drying process, water is removed from the food, which helps to inhibit the growth of bacteria and mold. This dehydration process also concentrates the flavors of the food, resulting in a longer shelf life and a more intense taste. Additionally, drying can make the food lighter and more convenient for storage and transportation.
The process that removes water from food is called dehydration. This can be done through methods such as air-drying, sun-drying, freeze-drying, or using specialized equipment like dehydrators. By removing the water content, the food becomes preserved and more shelf-stable.
The part of the body that helps dry out food is the mouth, specifically through the action of saliva. Saliva contains enzymes that begin the digestion process and can help break down food, but it also helps in the initial drying process as food is chewed and mixed. Additionally, as food moves through the digestive system, the stomach and intestines absorb moisture, further contributing to the drying out of food remnants.
Freeze drying food is primarily a physical change. This process involves removing moisture from the food while maintaining its chemical composition, typically by freezing it and then reducing the pressure to allow the ice to sublimate directly into vapor. Since the food's chemical structure remains intact and no new substances are formed, it is classified as a physical change.

Drying food by means of solar energy is an ancient process applied wherever food and climate conditions make it possible.
Drying and curing are both methods used to preserve food, but they differ in how they achieve this. Drying involves removing moisture from the food, which helps prevent the growth of bacteria and mold. Curing, on the other hand, involves adding salt, sugar, or other preservatives to the food to inhibit bacterial growth and enhance flavor.
During digestion, the stomach breaks down food into smaller pieces through the action of stomach acid and enzymes. This process helps to further break down food into nutrients that can be absorbed by the body. The stomach also churns and mixes the food to aid in digestion.

Preservation techniques were the same during the Great Depression as they were prior to it - canning, smoking, freezing during winter, drying.
There are many ways to preserve food like putting it in the fridge that slow down the bacteria process,by proper packaging the germs will not enter the food,by drying food etc
Drying is a method of food preservation that works by removing water from the food
Quote from the Related Link: "The basic process of freeze-drying food was known to the ancient Peruvian Incas of the Andes. Freeze-drying, or lyophilization, is the sublimation/removal of water content from frozen food." See the Related Link.
Drying is a method of food preservation that works by removing water from the food, which inhibits the growth of microorganisms and hinders quality decay. Drying food using sun and wind to prevent spoilage has been practised since ancient times, and was the earliest form of food curing. Water is usually removed by evaporation (air drying, sun drying, smoking or wind drying) but, in the case of freeze-drying, food is first frozen and then the water is removed by sublimation. Bacteria, yeasts and molds need the water in the food to grow, and drying effectively prevents them from surviving in the food.
There are several modern methods of food preservation, which include canning and freeze drying.
Cells release the chemical energy from food through a process called cellular respiration. During this process, the food molecules are broken down in the presence of oxygen to produce ATP, which is the cell's main source of energy. This happens in the mitochondria of the cell.
