Leaving space at the top of the jar, known as headspace, is necessary in canning to allow for the expansion of food and the formation of a proper seal during the heating process. This space accommodates the thermal expansion of the contents as they heat up and helps ensure that the lid can seal properly, preventing contamination and spoilage. Additionally, it allows for the escape of air bubbles, which can affect the integrity of the seal if not properly managed.

If you leave too much head space when canning fruit and the top of the fruit turns brown is it safe to use the fruit?

The simplest answer is it may not be. Too much headspace is the common reason for food spoilage in canning. It permits too much oxygen in the jar which promotes the growth of pathogens such as botulism. Canning really is a scientific art. If the recipe calls for 1/4 inch headspace, leave 1/4 inch headspace. Nothing more.

Let the canned jars sit for a day in plain view first. A couple of indications: You might hear the jars making a popping sound, after a day you can take the bands off of the jars and if the lid is loose, check the ingredients, possibly the lid did not seal.
