Jelly is sweet, fruity, and peanut butter’s best buddy. But here’s the million-dollar question: Does jelly need to be refrigerated?
The answer isn’t as simple as you might think. Some jellies thrive in the pantry, while others demand a chilly home in the fridge.
In this guide, we’ll cover what the science says, and give you expert advice along with storage hacks so you can keep your jelly fresh and delicious.
Does Jelly Need to Be Refrigerated?
The short answer: Yes! You should refrigerate jelly. Here’s why:
Room Temperature vs. Refrigeration: What Experts Say
1. USDA’s Take on Jelly Storage
According to the United States Department of Agriculture (USDA), opened jelly should be refrigerated to maintain quality and prevent microbial growth.
High-sugar jellies can last longer at room temperature, but low-sugar or sugar-free varieties are more prone to spoilage.
2. Food Scientists Weigh In
Experts from the National Center for Home Food Preservation recommend that you refrigerate jelly after opening to slow down bacterial growth and preserve texture.
While sugar acts as a natural preservative, refrigeration prevents mold formation and extends shelf life. Read their guidelines.
3. University Research on Jelly Preservation
Studies from Michigan State University Extension highlight that homemade jelly lacks commercial preservatives, which means refrigeration is essential for safety.
Canned jelly, however, can remain stable at room temperature until opened. Check out their research.
