How do you know that a chemical change is happening to the rice you are eating while it is still in your mouth?

In Biology,
Rice is made up of starch. Starch is a polysaccharide which is insoluble in water and does not taste sweet. However, the salivary glands secret saliva which contains salivary amylase. The salivary amylase catalyze the digestion of starch into maltose. A chemical reaction takes place as the structure of starch is changed and new substances are produced. Maltose is a disaccharide and is soluble in water. It tastes sweet. The change in taste suggests that a chemical reaction takes place to the rice while it is in our mouth.

Is pop rocks exploding on your tongue a chemical reaction?
No, it is not a chemical reaction. Pop rocks simply melt in your mouth and release trapped CO2 (Carbon Dioxide) out into your mouth, and this release is what causes you to hear a pop, much as in popping a balloon. A chemical reaction requires a substance to chemically change. Since the pop rock simply melts, it can always be cooled and would re-solidify. If this were to be a chemical reaction, the enzymes in your mouth, or the water, would have to change the pop rock candy in a way that the atoms of the molecules that make it up would re-arrange to form CO2, leaving behind a totally different substance in your mouth after. Note that this change would not be easily reversible - another tell-tale method of detecting a chemical reaction.
Is fire eating a chemical reaction?
Chewing the food is not really a chemical reaction. However, your saliva does partially break down the food in your mouth, which would be a chemical reaction in a way. The main part of the chemical reaction happens when the food goes into your stomach to be digested. There, it is broken down almost completely by the acids. Then, as the food moves through your intestines, and other organs, the food gets completely broken down until it comes out the other end.
Is it a chemical or physical change when pop rocks pop in your mouth?
The pop that results is caused by the release of carbon dioxide bubbles that are encapsulated within the candy. This is a physical change, rather than a chemical reaction, because no new products are formed.
How does the pH in the mouth change after eating?
you take your teeth brush with you and people
Is the taste of salt in water a physical or chemical change?
Taste is due to chemical reactions in the mouth.
When a person's mouth waters is that a physical change taking place or a chemical change?
When you put food in your mouth, two processes are at work to begin digesting.The first process is chewing. This causes a physicalchange in the food. In short, it changes shape and mixes with saliva.The second process is digestion by saliva. Saliva induces some chemical changes, such as the break down of starches into sugars.
When Food ground up in the mouth is it chemical change?
The act of grinding the food is not chemical change, as the same molacules are present in the same form, but there are many chemical reactions in the mouth (such as the breakdown of long chain carbohydrates), and other processes which aid digestion (mixture with mucus)
Why does your mouth itch after eating corn on the cob?

Why does soda make your mouth worse after eating something spicy?
There is a chemical in certain foods that make it spicy. The bubblyness in the soda just makes the chemical react more.
Does the first chemical change in digestion actually occur in the mouth with the help of the salivary glands?
yes
The first chemical change in digestion actually occurs in the mouth with the help of the salivary glands?
True
Is food digesting in your mouth a chemical or physical change?
the chewing in the mouth is part of digesting of food particularly carbohydrates. It is the only part of physical change because the food is only broken down to digestable particles. The rest of digestion (including the small intestines and stomach) are the parts encountering chemical change due to many enzymes and acids participating. The End.
What is mother's point of view?
its when you change every point of view into a mother talk example:I was eating french fries,and my mom told me to close my mouth. answer:My son was eating french fries,and I told him to close his 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.
