i know that its physical change because all you saliva is doing is making the food wet
The enzyme found in saliva that breaks chemical bonds between starches and releases sugars is called Salivary amylase.
A. The enzyme present in the human saliva is called salivary amylase and it starts the chemical digestion of starch. Also, there is another enzyme called lingual lipase which starts the chemical digestion of fats.
The enzyme in human saliva is Amylase.
Digestion involves both physical and chemical changes. The teeth crush food into smaller particles, which is a physical change, whereas the saliva, stomach, gall bladder, and pancreas contain chemicals that break down food chemically in the mouth, stomach, and small intestines.
Saliva contains the enzyme amylase, which breaks down starches into simpler sugars by cleaving the chemical bonds in these complex carbohydrates. This enzymatic action begins the process of digestion in the mouth, allowing for easier absorption of sugars later in the digestive system. The breakdown of starches into maltose and dextrin starts as soon as food is chewed and mixed with saliva.
Chemical, caused by saliva, without saliva you cannot taste anything

The first chemical change that happens in the body in regards to digestion, the breakdown of foodstuffs, occurs in the stomach. The saliva breakdown would be a physical change.
It has both chemical and physical components Chewing, of course, is a physical process. Additionally enzymes in the saliva and stomach break down food chemically.

No, melting ice is a chemical change where as carving ice is physical.... Another example is chewing food is physical where as enzymes in your saliva breaking down the food is chemical.
Saliva contains an enzyme called amylase which begins breaking down carbohydrates. Enzyme activity is chemical not mechanical so saliva does not "grind" anything.
saliva is the substance in the mouth that contains enzymes to help with digestion before the food is swallowed.
Saliva breaking down a piece of bread is a chemical change because enzymes in the saliva break down the starches in the bread into simpler sugars through a chemical reaction. This results in a change in the composition and structure of the bread at a molecular level.
An Enzyme speeds up a chemical reaction in an organism ex. enzymes in saliva
