Is Saliva breaking down bread is it a change of state?
Saliva breaking down bread involves a chemical reaction where enzymes in saliva break down complex molecules in bread into simpler ones for digestion. This is a chemical change rather than a change of state.
Is bread breaking a physical or chemical change?
Physical
Why is chewing bread for five minutes considered a chemical change?
The digestive process begins in your mouth. Some of the substances in the food -- sugars would be one category -- are completely broken into absorbable nutrients by saliva. So, for the bread -- a food containing chemicals that are chemically modified by saliva -- there will be chemical interaction in your mouth.
Why is the chewing of bread in the mouth a chemical change?
Chewing of bread is definitely a chemical change because the saliva in the mouth which is needed to lubricate the food it also contain a biocatalyst (alpha amylase or ptyalin) which converts the starch into the sugar. it can also be realized that when we chew food for more time it only in the mouth it give us sweet taste due to the chemical change of starch polymer inyo sugar molecules which are sweet in taste hence it clarifies there is a reaction even in our mouth while chewing the food.
Is slicing bread chemical change?
No, slicing bread is a physical change. The act of cutting the bread into smaller pieces does not alter its chemical composition.

What does the taste of bread change when mixed with saliva?
tasteless
Why does bread taste sweet after chewed for some time?
You saliva is adding enzymes that are start of the process of breaking down the starch in the bread into sugars (sweet).

What effects does saliva have on bread?
The effect on bread when mixed with saliva is a sweet taste which is because the saliva mixes in with the starch in the bread to make a horrible taste in your mouth if left for too long x
What is the role of saliva in the change of taste of bread?
Saliva plays a crucial role in the perception of taste by moistening food, allowing taste buds to effectively detect flavors. In the case of bread, saliva breaks down carbohydrates into simpler sugars, enhancing sweetness and altering the overall flavor profile. Additionally, enzymes in saliva can interact with the bread's components, further influencing taste perception as it is chewed and mixed with saliva. This enzymatic action contributes to the dynamic experience of tasting bread as it changes in flavor during consumption.
What reaction takes place when chewing a piece of bread for several minutes?
Chewing bread for several minutes mixes it with saliva, breaking down starch into simpler sugars through the action of enzymes in saliva like amylase. This process begins the digestion of carbohydrates, preparing them for absorption in the small intestine.

How would you expect the taste of bread to change during a period of 5 or 6 minutes?
The sugar that has been used to react with the yeast to make it rise. If you chew bread, particularly whit ebread for long enough you'll notice it takes on a slightly sweeter flavour.Alternate Answer: There is an enzyme in saliva, I believe it is Ptylin, that starts breaking down the starch in the bread and converts it to sugar and you get a sweeter taste after a few minutes of chewing.
Why when iodine and saliva and bread crumbs is added turns to purple?
When iodine is mixed with saliva and bread crumbs, it turns purple due to the presence of starch in the bread. Iodine reacts with the starch molecules, forming a blue-black complex, which can appear purple depending on the concentration and lighting. Saliva contains enzymes that begin to break down starch into simpler sugars, but the iodine interaction is primarily with intact starch. This color change is a common test for the presence of starch.
