Is fresh apple juice a pure substance?

A pure substance is a substance that has a definite and constant composition. Fresh apple juice is not a pure substance because its composition can vary depending on the type of apples used, the time of year the apples were harvested, and the method used to extract the juice. For example, apple juice made from sweeter apples will have a higher sugar content than apple juice made from tarter apples. Apple juice that is made from apples that were harvested in the fall will have a different flavor than apple juice made from apples that were harvested in the spring. And apple juice that is extracted using a juicer will have a different composition than apple juice that is extracted using a blender.

Fresh apple juice is a mixture of water, sugars, acids, and other compounds. The exact composition of fresh apple juice can vary depending on a number of factors, such as the type of apples used, the time of year the apples were harvested, and the method used to extract the juice.
