Are Strawberry Preserves Homogeneous or Heterogeneous?

Strawberry preserves like most natural substances is a mixture.

Making strawberry preserves is a way to save this summer fruit for use later in the year. Strawberry preserves are made from whole berries unlike strawberry jam, which is made from crushed strawberries.

How are Strawberry Preserves Made?

Strawberry preserves are made by cooking fresh, whole strawberries in a mixture of sugar and water for about fifteen minutes, then placing this mixture into sterilized canning jars. The result is softer berries in a thick, syrupy liquid.

What are Homogenous and Heterogenous Mixtures?

Most natural substances are a mixture, and those mixtures can be broken down into homogenous mixtures and heterogenous mixtures. In homogenous mixtures all the the different substances that make up the mixture cannot be distinguished from one another. Examples include white vinegar and air without clouds. A heterogenous mixture is made up of different substances that can be distinguished from one another. Examples include beach sand and air with clouds.

Why Strawberry Preserves are a Heterogenous Mixture

Even though the cooked strawberries that are used to make preserves become soft and mushy, the resulting mixture is still heterogenous because the different pieces of the mixture can still be seen. The different strawberry pieces are easily distinguishable from the sugary syrup. The hard strawberry seeds are clearly different from the runnier parts of the preserves.
