When saliva is added to cooked rice with Benedict's solution and heated, a color change may occur due to the presence of amylase in saliva, which breaks down starch into simpler sugars like maltose. Benedict's solution reacts with these reducing sugars, resulting in a color change from blue to green, yellow, or brick red, depending on the concentration of sugars present. This indicates the presence of carbohydrates that have been broken down by the enzymes in saliva.

Why does a cooked rice with Benedict's solution change its color when it is heated?
Benedict Solution is use to check the presence of Saccharides in food by changing the specimen's color like cooked rice when it puts a few drops of Benedict solution it change its color as yellow green. It means there is a presence of sugar in rice. About the Saliva thing, (Benedict Solution+Saliva+Cooked Rice) Saliva breaks the sugar into fragments so it helps the Benedict Solution to find the presence of sugar in rice, So it makes more yellow green than without Saliva one
Is saliva a solution?
Yes, saliva is a solution of hydrochloric acid, water, and other bodily fluids.
Why does dogs saliva does not contain amylase?
Because the food that they eat are not cooked
Action of saliva in carbohydrate solution?
lysozyme
What happened to the starch solution after you have added saliva?
Saliva contains enzymes that break down starch into simpler sugars like maltose. After adding saliva to a starch solution, the amylase enzyme in saliva breaks down the starch molecules into these simpler sugars, leading to a sweet taste in the solution due to the presence of maltose.
What colour is the colour when mixing saliva and water using the Benedict solution?
When mixing saliva, water, and Benedict's solution, the initial blue color of the Benedict's solution will change to green, yellow, orange, or red, depending on the presence and concentration of reducing sugars like glucose in the saliva. This color change is indicative of the amount of reducing sugars present in the solution.
Which enzymes are at work during digestion?
During digestion the enzyme in saliva works on cooked food
What color does saliva turn into with the Benedict's solution?
Benedict's solution changes colors (blue to green to yellow to orange to red) in the presence of "reducing" sugars, which are not normally present in saliva. An interesting experiment, however, is testing table sugar with Benedict's solution. Table sugar is a glucose sugar joined to a fructose sugar, so they cannot react with the Benedict's solution and no color change occurs. Put table sugar in your mouth for a few moments, and then test the saliva. Now the Benedict's solution will react! (The reason: saliva has an enzyme, amylase, which breaks the glucose and fructose apart so that they can react to the Benedict's.)
How do you explain when we add starch solution saliva dilute alkali and did not presence of starch and presence of glucose?
The enzyme amylase in the saliva broke the starch down into glucose.
What makes cooked chewed rice tastes sweet?
The saliva has enzymes that helps breakdown the starch and glucose that makes it sweet.
What happens if saliva goes down into your lungs?
then you cough for a few minutes
What happens to a cracker in a glass with saliva and vinegar?
it breaks down and dissovles
