You are eating dinner with your familiy one night. Your little brother (Who is a disgusting monster ) asked if you likes "seafood?" When you said yes, He proceeded to show you his chewed up, or "See Food". Did a chemical reaction take place, yes or no? What evidence or lack of evidence do you have to support your answer?

yes eating the food involves both physical and chemical changes. The chewing of food is a physical change, while the mixing of saliva with food triggers chemical reactions

Explanation:

Once the food mixes with the saliva in our mouth, chemical reactions start taking place in the food, leading to its breakdown and changes in its chemical composition. An evidence of the chemical changes is the taste that we feel when we eat something sweet or sour etc.
