If spaghetti sauce is expired and darker can you eat it?

No, you should discard it.

When spaghetti sauce expires, it can cause food poisoning. Food poisoning can cause symptoms such as vomiting, diarrhea, fever, and abdominal pain. In severe cases, food poisoning can even lead to death.

The darker color of the sauce is a sign that it has oxidized. Oxidation is a chemical process that occurs when food comes into contact with air. When sauce oxidizes, it can develop an unpleasant odor and taste, and its texture may change.

Even if the spaghetti sauce does not smell or taste bad, it can still be dangerous to eat. The bacteria that cause food poisoning can grow even in food that looks and smells fine.

Therefore, it is best to err on the side of caution and discard any spaghetti sauce that has expired.
