Question

Take a piece of bread and chew it for 3-4min. Why foes it taste sweet​

Answer 1

Answer:

bread tastes sweet after chewing for sometime

this is because of our saliva

Piece of bread is generally composed of starch molecules. After chewing it for long time, the enzymes in the mouth start attack the starch molecules which is further converted into glucose. It is the glucose which provides sweet taste. Thus, due to the action of enzymes the starch chains are converted into glucose
