Allulose vs Monk Fruit: What Does Each Do in a Food Formula?

What each ingredient does on its own

Allulose is a sugar used in enough quantity to contribute solids. Monk fruit extract is a high-intensity sweetener. The sweetness figures explain the difference in typical use level. The grade, dose and food still determine the result.

• FDA monk fruit extract reference
• Allulose specifications

At the nominal 70% reference, 100 g of allulose gives about the sweetness of 70 g of sucrose. Matching the nominal sweetness of 100 g of sucrose with allulose alone would take about 143 g, adding about 43 g of material. Use this calculation to see how mass and sweetness can move separately. Confirm the dose in your finished food.

How sweetness and bitterness change after the first taste

Match the samples for perceived sweetness, then compare the first taste and what remains after swallowing. In Mora and colleagues’ study, the tested monk fruit extract showed a broader sweetness profile and more bitterness than sucrose. The illustration shows the qualitative sweetness pattern. The original Figure 2 includes sucrose in panel a, allulose in panel b and monk fruit in panel g. In the original, solid lines show sweetness and dashed lines show bitterness. These profiles describe the tested solutions and grades. In a milk tea, record whether any lingering sweetness changes how clearly the tea comes through.

When the combination can work better

If allulose already gives the milk tea the body you want and the sample is still under-sweet, hold that dose steady and add a small amount of monk fruit extract in a second sample. Check whether the added sweetness leaves the body and tea flavor where you want them. If the drink already has the right body and just needs sweetness, start with the extract alone. If the amount of allulose you need also makes a biscuit too dark or too soft after cooling, address that first. Monk fruit extract can make the biscuit sweeter. The color or texture still needs its own adjustment.

How commercial products use allulose and monk fruit

The same two ingredients show up in tabletop blends, supplier premixes and finished foods. Read the product label to see whether the ingredients were premixed or used in different parts of the food.

• Lakanto Classic blend ingredient list and use instructions
• Lakanto’s published chocolate chip cookie recipe
• Icon Foods KetoseSweet product #2108 specification
• Rebel Chocolate Peanut Butter Ice Cream ingredient list

For a cookie, keep the dough base consistent and compare color and texture after cooling. In a frozen dessert with a swirl, decide which part needs more sweetness or a change in texture. That tells you whether to trial the two ingredients separately or start with a premix.

Drinks: compare milk tea and tart fruit drinks separately

For milk tea, keep one cup of the current recipe. If it is under-sweet, try a monk fruit extract sample. If it is sweet enough but thin, compare an allulose sample. Account for the water a syrup adds. Taste at the intended serving temperature, and check the drink again after the planned processing and storage. For lemon tea or a tart fruit drink, test at the actual acidity. In a water-based study by Junge and colleagues, added citric acid suppressed early sweetness more for sucrose and allulose alone than for the allulose–monk fruit blend they tested. The samples had different starting sweetness levels. Keep your tea base and acid level fixed when you compare how sweet and sour the first sip tastes and what remains in the finish.

Cookies: check the cooled bite and the packaged product

For a soft cookie, extra color and moisture may suit the target. For a pale biscuit that needs to stay crisp in the bag, track color, spread and cooled texture separately. Find the texture you want before using monk fruit extract to close a sweetness gap. KetoMe reported that several cookies made with an allulose and monk fruit blend were soft and moist, but some became too delicate during storage and shipping. That is one bakery’s experience. If the product needs to ship, check the cooled cookie, the packed cookie and its condition after transit.

Published biscuit trial: equal mass did not preserve the product

Gomez-Betancur and colleagues (2025) prepared wire-cut biscuits with 94.5 g of each test sugar per batch, using allSweet allulose for the allulose treatment. They baked at 205°C for 11 minutes, made three baking replicates, and assessed biscuits after 24 hours. Moisture and water-activity analyses used duplicate measurements per baking replicate. The recipe also contained HFCS; this was not a sugar-free finished-product trial. Table 1 reports moisture of 2.68% for sucrose biscuits and 6.47% for allulose biscuits, with widths of 8.54 and 7.15 cm respectively. Water activity was 0.26 versus 0.50, and the allulose biscuits were darker. These measured differences show why equal replacement mass needs a separate physical-performance check.

• Original paper, Table 1 and methods, university repository

These are published means from one formulation. The paper found no significant difference in fracture strength between sucrose and allulose in that experiment; a numerical difference alone is not proof of a harder biscuit. There was no monk fruit arm. The results do not establish a shelf life, a preferred blend ratio or the performance of Hengliyuan ingredients.

Ice cream: check the hardened product

A small amount of monk fruit extract can restore sweetness. Scoopability still depends on the complete frozen mix. Allulose can affect freezing and the hardened texture. Compare samples in the same base, at the same serving temperature, after the same hardening and storage period. Check scoopability, smoothness and melt separately. If the texture meets the target but sweetness falls short, test the blend as a separate sample.

Calories and cost depend on the finished recipe

U.S. FDA guidance describes enforcement discretion for using 0.4 kcal/g for allulose and excluding it from Total Sugars and Added Sugars. It remains in Total Carbohydrate. Ten grams of allulose contributes 4 kcal by that factor. Monk fruit extract is usually used at a much smaller dose. When using a blend, calculate each serving from the complete ingredient list and actual amounts. Check the rules in the destination market. Trial separate ingredients if you still need to adjust body and sweetness independently. Once a formula meets the target, compare a supplied blend against it. Compare the cost per unit of accepted output, using the actual amounts of sweeteners and any solids or processing the recipe needs.

Start with the current recipe and one trial

Keep the current formula as your reference. Choose a first candidate based on the problem you can describe and measure.

Tell Hengliyuan what you need the sample to do

Send the product type, the sweetener you use now, the change you want and the destination market. For example, “We make a chilled milk tea. The sweetness is right, but it feels thin.” We can discuss a starting sample and confirm the selected material’s form, specification and available documents.
