Spaghetti sauce, a culinary staple in many households, offers a convenient and flavorful base for countless dishes.

Factors Affecting Shelf Life
The longevity of unopened spaghetti sauce depends on several factors:
- Acidity Level: The acidity of the sauce, determined by the presence of tomatoes, vinegar, or citric acid, plays a significant role in preserving its freshness. More acidic sauces have a longer shelf life.
- Preservatives: Some commercial spaghetti sauces contain preservatives such as sodium benzoate or potassium sorbate, which help inhibit bacterial growth and extend shelf life.
- Packaging: The type of packaging used can also influence the sauce’s lifespan. Glass jars provide better protection against light and air than plastic containers.
Storage Conditions
Proper storage is essential to maximize the shelf life of unopened spaghetti sauce:
- Cool and Dry Location: Store the sauce in a cool, dry place away from heat sources and direct sunlight. The ideal temperature range is between 50°F (10°C) and 70°F (21°C).
- Refrigeration: Once opened, spaghetti sauce should be refrigerated at 40°F (4°C) or below.
Shelf Life Guidelines
Based on the factors discussed above, unopened spaghetti sauce typically has the following approximate shelf life:
- Commercially Produced, Unopened:
- Glass Jars: 12-18 months
- Plastic Containers: 6-9 months
- Homemade, Unopened:
- Glass Jars: 6-9 months

Signs of Spoilage
While unopened spaghetti sauce has a relatively long shelf life, it’s important to be aware of signs of spoilage:

Discarding Spoiled Sauce
If you suspect that your unopened spaghetti sauce has spoiled, discard it immediately to avoid potential foodborne illnesses. Do not taste or use the sauce if any of the signs of spoilage are present.

To extend the shelf life of unopened spaghetti sauce, consider the following tips:
