Food additives
Food additives: - A substance added to food during processing to improve colour, texture, flavour or keeping qualities. The E stands for European which means it is approved by Europe.
Digestion and Absorption: -
Digestion is the breakdown of food into smaller particles or individual nutrients. It is accomplished through six basic processes, with the help of several body fluids—particularly digestive juices that are made up of compounds such as saliva, mucus, enzymes , hydrochloric acid, bicarbonate, and bile . The six processes of digestion involve: (1) the movement of food and liquids; (2) the lubrication of food with bodily secretions; (3) the mechanical breakdown of carbohydrates, fats, and proteins; (4) the reabsorption of nutrients—especially water; (5) the production of nutrients such as vitamin K and biotin by friendly bacteria; and (6) the excretion of waste products.
Digestive System and organs:- Digestion involves mixing food with digestive juices, moving it through the digestive tract, and breaking down large molecules of food into smaller molecules. Digestion begins in the mouth, when you chew and swallow, and is completed in the small intestine.
Movement of Food through the System
The large, hollow organs of the digestive tract contain a layer of muscle that enables their walls to move. The movement of organ walls can propel food and liquid through the system and also can mix the contents within each organ. Food moves from one organ to the next through muscle action called peristalsis. Peristalsis looks like an ocean wave travelling through the muscle. The muscle of the organ contracts to create a narrowing and then propels the narrowed portion slowly down the length of the organ. These waves of narrowing push the food and fluid in front of them through each hollow organ.
The first major muscle movement occurs when food or liquid is swallowed. Although you are able to start swallowing by choice, once the swallow begins, it becomes
