Does homemade or store bought spaghetti sauce have more acid and why?

Homemade spaghetti sauce typically has less acid than store-bought sauce. This is because most store-bought sauces contain citric acid or vinegar as preservatives, while homemade sauces do not. Additionally, the natural acidity of tomatoes can vary depending on the type and ripeness of the tomatoes used, so homemade sauces can be adjusted to taste. In comparison, store-bought sauces are made using a standardized recipe and may not be as customizable.
