Sugar-Free Pineapple Jam (No Pectin)

This small-batch pineapple jam uses chia seeds instead of pectin for a bright, spreadable refrigerator jam with no added sugar.

Sugar Free Pineapple Jam Without Pectin

Finely diced pineapple softens quickly, while chia seeds absorb moisture as the mixture cools. The result is spoonable rather than the firm gel of a traditional high-sugar preserve.

Prep time: 10 minutes

Pineapple, allulose, chia seeds, lemon, water and salt for sugar free jam — Measure every ingredient before heating because the mixture thickens quickly near the end.

Ingredients

3 cups finely diced fresh pineapple, about 18 oz
1/4 cup granulated allulose
2 tablespoons water
2 tablespoons fresh lemon juice
3 tablespoons chia seeds
1/8 teaspoon fine sea salt

Here, sugar free means no added sugar. Pineapple contains naturally occurring sugar, so include the fruit when tracking total carbohydrate or blood glucose.

How to Make Sugar-Free Pineapple Jam

Wash one 2-cup heat-safe jar and its lid in hot, soapy water. Rinse and air-dry.
Add pineapple, allulose, water, lemon juice, and salt to a 2-quart saucepan.
Cook over medium heat for 5 minutes, stirring every 30 seconds.
Reduce the heat to medium-low when the fruit bubbles steadily.
Simmer for 8 minutes, stirring every 1 to 2 minutes.
Mash the pineapple with a potato masher until only 1/4-inch pieces remain.
Stir in the chia seeds and simmer for 5 additional minutes.
Remove the pan when a spoon drawn across the bottom leaves a visible trail for 2 seconds.
Cool in the pan for 20 minutes.
Transfer to the clean jar and refrigerate within 2 hours of leaving the heat.
Chill for at least 2 hours before judging the final thickness.

How to check the texture

The hot mixture should look slightly loose. Chia continues absorbing liquid during the 2-hour chill, creating a thicker and more even spread.

Texture Adjustments

Too thin after chilling: Stir in 1 teaspoon chia seeds and refrigerate for 30 minutes.
Too thick: Stir in 1 tablespoon cold water until evenly combined.
Too chunky: Pulse the cooked mixture 3 times with an immersion blender before adding chia.
Too tart: Stir in 1 tablespoon allulose while the jam is still warm.

Storage and Food Safety

Keep the sealed jar refrigerated at 40 degrees F or colder.
Use the refrigerated jam within 7 days.
Freeze for up to 3 months in a freezer-safe container with 1/2 inch headspace.
Thaw overnight in the refrigerator and stir before serving.
Discard the entire batch if you see mold, bubbling, leakage, or detect an off odor.
This is not a shelf-stable canning recipe.
Do not process this formula in a water-bath canner.

For another tropical spread, try mango chia jam. Compare the texture with sugar-free peach jam or make raspberry chia jam.

Sugar-Free Pineapple Jam FAQ

Can I use frozen pineapple?

Yes. Thaw it completely, drain excess liquid, and measure 3 cups. Expect 2 to 3 additional minutes of simmering if the fruit remains watery.

Can I use canned pineapple?

Use pineapple packed in juice rather than syrup. Drain it thoroughly, measure 3 cups, and begin checking the spoon trail after 10 minutes of simmering.

Does allulose make the jam shelf-stable?

No. Allulose sweetens the fruit but does not turn this refrigerator recipe into a tested shelf-stable preserve. Keep it cold and follow the stated storage limits.

Why does the jam separate?

Chia may settle before it hydrates fully. Stir the chilled jam for 15 seconds; if liquid remains, add 1 teaspoon chia and chill for 30 minutes.
