What chemical reaction do cookies make?

User Avatar

Asked by Wiki User

Cookies undergo a series of chemical reactions when baked. The heat causes ingredients like sugars and proteins to react, resulting in Maillard browning, caramelization of sugars, and the release of carbon dioxide from leavening agents, causing the cookies to rise and develop their characteristic flavor and texture.

What are the pigments formed during the Maillard reaction are called?

User Avatar

Asked by Wiki User

The pigments formed during the Maillard reaction are called melanoidins. These pigments are responsible for the brown color and flavor development in cooked foods.

Is a potato in salt water Hypertonic hypotonic or isotonic?

User Avatar

Asked by Wiki User

A potato in salt water is hypotonic. This is because the salt water has a higher concentration of solutes compared to the potato cells, causing water to move out of the potato cells, leading to the cell shrinking.

How does the taste of a food change the longer you chew it?

User Avatar

Asked by Wiki User

As you chew food, the enzymes in saliva begin breaking down the food molecules, releasing more of the flavors and allowing your taste buds to properly sense them. This prolonged chewing process can intensify, alter, or diminish the taste depending on the food, resulting in a more nuanced flavor experience.

Why does sugar dissolve more in hot tea than in cold tea?

User Avatar

Asked by Wiki User

Sugar dissolves more quickly in hot tea because higher temperatures increase the kinetic energy of the sugar molecules, allowing them to move faster and interact more readily with the solvent molecules in the tea. This results in faster dissolution compared to cold tea where the molecules move more slowly and are less likely to interact effectively.

Are polysaccharides bonded by ester?

User Avatar

Asked by Wiki User

No, polysaccharides are not bonded by ester bonds. Polysaccharides are typically composed of monosaccharide units linked together by glycosidic bonds, which are formed through dehydration reactions. Ester bonds are formed between a hydroxyl group and a carboxyl group, commonly found in lipids but not in polysaccharides.

Can you hybridize more than two crops?

User Avatar

Asked by Wiki User

Yes, it is possible to hybridize more than two crops through controlled pollination techniques in a process called multi-parental or nested association mapping. This approach can help create diverse genetic combinations and increase the likelihood of producing plants with desirable traits.

What does adding salt to water do?

User Avatar

Asked by Wiki User

Adding salt to water increases its boiling point, so it will take longer for the water to reach the boiling point and evaporate. Additionally, salt lowers the freezing point of water, making it harder for the water to freeze.

How is chocolate melting related to an amorphous solid?

User Avatar

Asked by Wiki User

Chocolate melting is related to an amorphous solid because chocolate has a disordered atomic arrangement, similar to that of an amorphous solid. Upon heating, the atoms in chocolate move more freely and lose their ordered structure, leading to the transformation from a solid to a liquid state.
