Whole pomegranates last one to two weeks at room temperature and up to two months in the refrigerator. But the seeds (arils), juice, and processed forms each have their own best storage methods, and choosing the right one depends on how soon you plan to use them. Here’s how to get the most life out of every part of the fruit.
Picking a Pomegranate That Will Last
Preservation starts at the store. A pomegranate that’s already past its prime won’t hold up no matter what you do. Look for three things: a rounded, slightly square shape (not perfectly round, which signals it was picked early), smooth and firm skin without soft spots, and noticeable heft. A heavy pomegranate is full of juice-packed arils. Multiple soft spots on the skin mean the fruit is overripe and already losing quality inside.
Internal mold is one of the trickier problems with pomegranates because it can develop without any obvious signs on the outside. A fungal condition called heart rot starts in the flower end and works inward, sometimes affecting most of the interior while the skin still looks fine. If you cut open a pomegranate and find dark, mushy, or fuzzy patches around the arils, discard that portion. There’s no reliable way to detect this from the outside, which is another reason to buy from a source with good turnover and refrigerated displays.
Storing Whole Pomegranates
At room temperature, keep whole pomegranates on the counter away from direct sunlight. They’ll stay good for one to two weeks, but they lose moisture quickly in warm conditions. Research on fruit stored at around 72°F (22°C) found weight loss of 20 to 25 percent within four weeks, with complete quality loss shortly after. Heat accelerates that decline significantly.
Refrigeration is by far the better option. At roughly 41°F (5°C) with high humidity, whole pomegranates can last two to three months depending on the variety. Commercial storage facilities keep them at 32 to 50°F with humidity above 90 percent, achieving shelf lives of two to five months. You won’t match those humidity levels in a home fridge, but storing pomegranates in the crisper drawer (set to high humidity if your fridge has that option) or loosely wrapping them in a paper towel inside a perforated plastic bag helps slow moisture loss.
One thing to keep in mind: bruised pomegranates deteriorate faster. Even minor impact damage increases both the rate of moisture loss and the production of ethylene, a ripening gas. Handle them gently, and store bruised fruit separately so you can use it first.
Refrigerating Pomegranate Arils
Once you’ve seeded a pomegranate, the arils are much more perishable than the whole fruit. Fresh arils keep in the refrigerator for up to five days. Store them in an airtight container lined with a paper towel to absorb excess moisture, which is the main driver of mold at this stage. If you notice any slimy or off-smelling arils, remove them so they don’t spoil the rest.
This five-day window also applies to fresh-pressed pomegranate juice stored in the fridge. Pour it into a glass jar, fill it as close to the top as possible to minimize air exposure, and seal it tightly.
Freezing Arils for Long-Term Storage
Freezing is the easiest way to keep pomegranate arils for months. The key is flash freezing them in a single layer first so they don’t clump into one solid block.
- Spread the arils in a single layer on a baking sheet lined with parchment or wax paper. Make sure none are touching.
- Freeze for one to two hours until the arils are solid.
- Transfer to a freezer-safe bag or container. Squeeze out as much air as possible from bags, or line rigid containers with a paper towel to absorb any ice crystals that form.
Frozen arils will keep for several months. They’re great added directly to smoothies, yogurt, or oatmeal without thawing, or you can let them defrost in the fridge for about an hour. Thawed arils will be softer than fresh ones, but the flavor stays intact.
Nutritionally, freezing preserves most of what makes pomegranates valuable. The antioxidants (specifically anthocyanins, the compounds responsible for that deep red color) decrease by about 11 percent after 20 days of frozen storage at roughly 13°F below zero. That’s a modest loss. The compounds most affected dropped by only 3 to 6 percent individually. For practical purposes, frozen pomegranate retains the large majority of its nutritional value.
Freezing Pomegranate Juice
Fresh pomegranate juice freezes well. Pour it into ice cube trays for portioned use, or fill freezer-safe jars leaving about an inch of headspace (liquid expands as it freezes, and a full jar can crack). Once juice cubes are solid, pop them out and store in a freezer bag. This gives you easy single-serving portions for drinks, marinades, or sauces.
Frozen juice maintains good quality for several months, though some antioxidant content does decline gradually through oxidation, just as it does with frozen arils.
Making Pomegranate Molasses
Pomegranate molasses is a thick, tangy syrup used in Middle Eastern and Mediterranean cooking. It’s also one of the most shelf-stable ways to preserve pomegranate flavor. The process is simple: reduce pure pomegranate juice over low heat until it thickens into a syrup that coats the back of a spoon.
The standard ratio is about 4 cups of juice reduced down to roughly 3/4 cup of finished molasses. Start at a simmer (medium-low heat) and stir occasionally. It takes 45 minutes to over an hour depending on your stove. The molasses will thicken further as it cools, so pull it off the heat when it’s still slightly thinner than your target consistency. Some recipes add a tablespoon of lemon juice or a small amount of sugar, but pure juice works on its own if it has enough natural tartness.
Store-bought pomegranate molasses keeps in a cool, dark pantry for at least a year. Homemade versions, because they lack commercial preservatives, are best stored in a clean glass jar in the refrigerator, where they’ll last several months. Make sure the jar is sealed tightly.
Dehydrating Pomegranate Arils
Dried pomegranate seeds, sometimes called anardana, are used as a spice in South Asian cooking and as a crunchy snack. You can dry them in a food dehydrator or a conventional oven set to its lowest temperature (typically 135 to 150°F). Spread arils in a single layer on dehydrator trays or a parchment-lined baking sheet. The process takes anywhere from 8 to 12 hours in a dehydrator, or 6 to 10 hours in an oven with the door cracked slightly to allow moisture to escape.
The arils are done when they feel dry and slightly crunchy, with no remaining stickiness. Store them in an airtight container in a cool, dark place. Properly dried arils last for months at room temperature and even longer in the freezer. They won’t rehydrate to their original juicy texture, so think of them as a different ingredient altogether: tart, chewy, and concentrated in flavor.
