Modeling Matter Review

Front

What is the purpose of emulsifiers in food production?

Back

Emulsifiers are texture ingredients that cause liquids that normally don’t mix to mix and form a stable mixture.

Front

Do all liquids have the same level of attraction between their molecules?

Back

False

Front

What happens to some liquid mixtures over time?

Back

Some liquid mixtures stay mixed, while others separate into layers.

Front

What occurs when oil and water are mixed?

Back

The mixture separates into layers over time.

Front

What ingredients are best for making salad dressing?

Back

Oil, vinegar, citric acid, and sugar.

Front

What is an emulsion?

Front

What role does citric acid play in salad dressings?

Back

Citric acid acts as a flavor enhancer and preservative.

Front

Why do some mixtures separate into layers?

Back

Mixtures separate into layers due to differences in density and molecular attraction between the components.

Front

What is the difference between a homogeneous and heterogeneous mixture?

Back

A homogeneous mixture has a uniform composition throughout, while a heterogeneous mixture has distinct, separate components.

Front

How do emulsifiers affect the texture of food products?

Back

Emulsifiers improve the texture by creating a stable mixture that enhances mouthfeel and consistency.
