What Is Allulose? Forms, Formulation and Label Checks

Allulose vs. erythritol: sweetness, taste and uses

Allulose is a monosaccharide. Erythritol is a sugar alcohol. Both are bulk sweeteners, so compare what each one does to ingredient mass and texture as well as sweetness. Start with the same product base and a similar sweetness target.

How much matches the sweetness of sugar? In a published water-solution study, matching 5, 10 and 15 g of sucrose per 100 mL took 7.1, 13.3 and 18.9 g of allulose per 100 mL. The corresponding erythritol amounts were 6.9, 13.3 and 17.8 g per 100 mL. Both matched the 10 g reference at 13.3 g per 100 mL in that study.

The linked curves in Mora et al. show a separate 90-second experiment measuring sweetness and bitterness over time. Figures 2b and 2c compare allulose and erythritol with sucrose and reduced-sugar blends. The study scored cooling separately.

In ice cream, check what is crystallizing. Ice crystals can grow during storage, and dissolved erythritol can also recrystallize. If a sample turns grainy, identify the likely source before changing the formula. Compare a sugar control, allulose and erythritol in the same base at the same frozen-storage and serving temperatures.

When bulk and texture already work and the sample needs more sweetness, a small addition of stevia or monk fruit extract is another direction to test. Read the full ingredient list on retail sweeteners, which may already contain a blend.

How is allulose made?

Commercial production typically starts with fructose. An enzyme converts part of the fructose into allulose. The liquid then goes through separation and purification to remove remaining fructose and other components. Public process descriptions include steps such as chromatographic separation, decolorization and desalting. The purified liquid can be concentrated into syrup. Crystallization and drying produce crystalline powder. One FDA-notified example uses corn-derived sugars. Confirm the feedstock, manufacturing route and documents for the material you are offered.

• FDA: sugars and sugar alcohols are different ingredient classes
• FDA-filed allulose manufacturing example (GRN 893)
• Food Chemicals Codex: allulose powder
• Food Chemicals Codex: allulose syrup

For powder, check allulose content and moisture. For syrup, check the solids level and whether allulose is reported as a percentage of the syrup or of its solids.

Powder, syrup or a blend: which form should you test?

Choose the form that fits how you weigh, mix and process the ingredient. Powder contributes a dry ingredient; syrup also brings water; a blend introduces the other ingredients listed in its composition. Compare each against the same finished-product target, recording the actual dose rather than copying a dose from a different form.

• Allulose powder versus syrup sourcing guide

A buyer example: separating product form from packaging

A Peruvian food business comparing allulose and monk fruit ingredients initially asked for a sugar-like granulated texture and own-brand packs. In the published exchange, the buyer confirmed that powder was acceptable for the proposed route and chose separate bulk bags with local retail repacking. This clarified what to specify and quote. It was not a finished-formula trial, confirmation of an order or proof that powder and granules perform identically. For your project, identify the ingredient and physical form before deciding who fills the retail pack. A bulk ingredient and a ready-to-use retail blend need different specifications. For the next quotation, specify the exact ingredient and form, whether you need bulk bags or filled retail packs, and who handles local repacking. This gives both sides the same item to quote.

Syrup solids and allulose content are different numbers

A solids figure describes the material left after water is excluded; it does not identify how much of those solids is allulose. Read the specification for both values and their reporting basis. Do not treat a refractometer reading alone as a direct allulose assay. Here is a hypothetical mass-balance example: 100 g of syrup at 70% solids contains 70 g of solids and 30 g of water. If allulose makes up 95% of those solids, the syrup contains 66.5 g allulose and 3.5 g other solids. Allulose mass = syrup mass × solids fraction × allulose fraction of solids. These are calculation inputs, not a Hengliyuan specification. For a real sample, use its confirmed assay and solids basis. Count syrup water in the formula, identify the remaining solids, and do not substitute the same weight of powder without recalculating the balance. Matching allulose mass is only a starting point for the application trial.

How sweet is allulose compared with table sugar?

Allulose is commonly described as about 70% as sweet as sucrose. FDA's labeling guidance discusses this approximate comparison in its background section. It helps explain why replacing sugar with the same weight of allulose may taste less sweet; it is not a fixed conversion for every recipe.

For coffee or a drink, compare at the intended serving temperature and with the actual milk, acid or flavor system. For baking, assess the cooled product as well as the batter. If you increase allulose to reach the sweetness target, recalculate ingredient mass and the complete formula rather than changing the dose alone. A blend with a high-intensity sweetener is another direction to test.

A separate 2018 sensory study compared 16 sweeteners, including allulose and mogroside V, across concentration series in 40 participants. Its dose-response method illustrates why a comparison should identify the concentration and sweetness target. It does not establish one replacement ratio for a finished drink or baked food.

Equal weight and equal sweetness give different calculations. At the rough 70% reference, 10 g of sugar would correspond to about 14.3 g of allulose. Use this as an initial trial estimate. Recalculate the solids, water and complete formula at the amount that works in your product.

How many calories does allulose contribute?

For U.S. Nutrition Facts calculations, FDA guidance describes using 0.4 kcal per gram for allulose under enforcement discretion. The U.S. nutrition-label rule lists 0 kcal per gram for erythritol. With table sugar at 4 kcal per gram, the table shows how much energy 10 g of each ingredient contributes before rounding. This compares equal ingredient weights. Calculate finished-product calories from the actual amounts used and the complete serving.

• FDA: allulose and traditional-sugar energy factors
• 21 CFR 101.9(c)(1)(i)(F): U.S. erythritol energy factor

Why can a retail label show 0 Calories?

The ingredient calculation and the number declared per serving answer different questions. Under U.S. Nutrition Facts rules, an amount below 5 Calories per serving may be expressed as zero. For a hypothetical serving containing only 7 g of allulose, the FDA factor gives 7 × 0.4 = 2.8 kcal before rounding. Other ingredients add energy, and the serving must be determined under the applicable rules. A zero shown after rounding does not mean the ingredient has zero energy at every quantity. Nutrition Facts rounding does not by itself clear a front-of-pack calorie-free or sugar-free claim. Review the complete formulation, actual serving and applicable claim conditions separately.

• 21 CFR 101.9(c)(1): calories per serving and rounding
• FDA allulose guidance: the 0.4 kcal/g labeling context

Does replacing half the sugar halve a recipe’s calories?

Calculate the energy from the changed ingredients first, then recalculate the complete recipe. For an equal-weight illustration using the U.S. factors above, 100 g of table sugar contributes 400 kcal. Replacing half of it with allulose gives the calculation below.

• FDA: allulose and traditional sugar energy factors

This is a 45% reduction in energy from these sweetening ingredients: (400 − 220) ÷ 400. It is not a 50% reduction in the whole recipe, and it does not establish equal sweetness or identical texture. Fat, flour, milk and other ingredients still count. These are arithmetic examples, not Hengliyuan trial results.

Why does a sugar swap change browning and frozen texture?

Sweetness is only one function of sugar in a food. Cargill’s published application discussion describes allulose participating in Maillard browning and retaining water in bakery systems. Changing the sweetening ingredients can therefore change colour and texture as well as sweetness. Compare the bake conditions and the cooled or stored product, rather than judging the batter alone. The same publication identifies freezing-point depression and solubility as important in allulose–erythritol frozen-dessert systems. If you restore sweetness with a high-intensity ingredient, check the finished product’s hardness, scoopability and texture separately. A similar sweetness score does not establish that the physical properties match. These published application observations explain what to investigate. They are not results for a Hengliyuan sample, a universal blend ratio or a promise of shelf life.

• Allulose baking: browning, moisture and sample testing

Can you replace sugar with allulose in drinks and baking?

Allulose can be considered for drinks and baked foods, but replacing sugar changes more than the sweetener name. Keep your current product or sugar formula as a control. Compare sweetness, ingredient mass and processing behavior separately. A blend designed for a particular replacement is different from plain allulose powder. When switching between powder and syrup, record the water adjustment explicitly. Use the first trial to answer a defined question with the same base and preparation conditions where possible. The fields below are a trial plan, not results from a Hengliyuan experiment.

• Compare allulose samples in beverages and baking

Do not assume that an equal-weight sugar swap will reproduce sweetness, body and processing behavior. Choose the direction against the result you need, then confirm its specification and continue the relevant stability and shelf-life work.

A public blend percentage is not an extract specification

Chris Powell’s caption and spoken video describe years of using allulose in baking and ice cream and suggests a 90% allulose / 10% monk-fruit combination. That is his reported preference. Neither identifies the monk-fruit material’s concentration, extract grade or other blend ingredients, so the percentage cannot be transferred to concentrated monk fruit extract as a manufacturing formula. First identify whether monk fruit means a standardized extract or an already diluted retail blend. Then record each material by mass, the extract assay, any carrier and the actual addition used to match sweetness in the food. Percent of blend, percent mogroside V and sweetness contribution are different quantities. Use a public combination as a direction to investigate, then agree the actual sample specification and dose. His video also separates animal GLP-1 findings from a human post-meal claim and says more human research is needed. Those are different evidence questions. A change in a hormone or meal-test response should be traced to its own human study, rather than treated as a measured outcome of his baking blend.

GLP-1 discussion needs the original study, not the headline

Thomas DeLauer’s September 2023 video discusses allulose and GLP-1, but its spoken opening explicitly says allulose will not replace semaglutide. The description discloses a paid partnership, and the GLP-1 paper linked there studied rats. Those distinctions matter more than the suggestion in the video title. The linked 2018 study found a GLP-1 response to oral allulose in rats. It provides a mechanistic research lead, not a human dose instruction, evidence of equivalence to a medicine or a benefit demonstrated for your finished food. A 2026 human allulose-versus-aspartame publication is explicitly a study protocol; its published plan and completion of sample collection are not the final GLP-1 result. Do not present a protocol, an animal experiment or a creator’s experience as a completed human efficacy trial. Individual human trials and pooled findings also need to be read together. Han and colleagues’ preliminary 2018 trial studied 121 Korean adults aged 20–40 with BMI at least 23 kg/m², using 8 or 14 g allulose per day versus a sucralose control for 12 weeks. It reported favorable body-fat outcomes, but no significant reduction in visceral fat area; industry researchers were among the authors. This is a research result for that intervention and population, not proof that a sweetened food reduces belly fat. The 2026 controlled-trial review discussed in our comparison guide reported post-meal effects for allulose but no significant pooled improvement in body composition. A favorable individual study and a null pooled estimate should both remain visible. Neither supports a weight-loss, diabetes-treatment or drug-equivalence promise for a new food.

Human meal studies: retain the dose, comparison and endpoint

There are human meal studies as well as animal mechanisms and study protocols. Their results depend on the carbohydrate challenge, population, dose and endpoint; they do not support a fixed percentage benefit for every meal or finished food. A 2026 exploratory investigation tested 10 g allulose with a rice-based reference meal containing 75 g available carbohydrate in 10 normal-BMI adults with elevated fasting glucose. Over 180 minutes, reported glucose iAUC was lower and GLP-1 total AUC was higher than with the meal alone. Subjective satiety did not significantly increase. The single-blind pilot was funded by Samyang Corporation.

• 2026 exploratory human meal study: full report and funding

Read the human findings alongside the protocol and animal work above, and the pooled outcomes discussed in our comparison guide. For development, keep the tested material, serving exposure and complete food with the result. Replacing an ingredient or adding a small amount to a recipe does not reproduce a clinical meal challenge.

What about digestive tolerance and product claims?

Human tolerance studies have reported gastrointestinal symptoms after allulose consumption, with results depending on the dose and study conditions. A 2018 study used increasing doses in healthy young adults; a 2026 study followed healthy Chinese adults for 30 days. Neither establishes one intake limit for every consumer or proves long-term safety for a finished product. For development, consider the allulose amount per serving, likely repeat servings and the other ingredients in the formula. Assess the intended use with the relevant product and regulatory specialists. Ingredient research does not justify claims that a food treats diabetes, guarantees weight loss or is suitable for everyone.

• Han and colleagues, 2018: original tolerance study and limitations
• 2026 fermented-allulose trial: population, doses, symptoms and scope

The 2026 trial compared two allulose doses; it did not include a no-allulose placebo group. Its symptom incidence should not be interpreted as a measured excess versus no intake. For a product brief, calculate grams per serving and plausible repeat servings, identify other polyols or fibres and retain the intended consumer and use conditions. A statement such as “30 g a day is fine” is too broad to replace that assessment.

Does an allulose ingredient settle the finished-product label?

The U.S. label treatment is specific. FDA guidance describes enforcement discretion for excluding allulose from Total Sugars and Added Sugars, and for using the 0.4 kcal/g energy factor shown above. Allulose remains included in Total Carbohydrate. These are nutrition-label accounting rules. They do not make a commercial allulose ingredient a zero-carbohydrate product or automatically clear a sugar-free statement.

• FDA guidance on allulose labeling and calories
• Market access and labeling notes for allulose

Apply the destination market’s current requirements to the complete formulation and final serving. Check other sugars and ingredients separately. The FDA guidance is not global permission to use allulose or a guarantee that a finished product qualifies for a claim. Keep the label decision with the product and regulatory team. For a new U.S. allulose project, identify the main sales state before approving packaging wording; review the current project-specific claim restrictions separately.

Move from an ingredient question to a sample decision

Start with the product you are developing, the destination market and the question you want the sample to resolve. If you already know whether you need powder, syrup or a blend, include that; if not, we can discuss the options.

A current control, target dose or ingredient restrictions help narrow the comparison, but you do not need a complete formulation to begin. Hengliyuan can discuss the relevant material, sample and matching documents. Confirm the exact specification, packing and commercial terms for the selected order.

For the first sample request, send four details. Tell us the product, destination market, preferred powder or syrup if known, and the main question you want to answer. For example, for a chilled lemon drink, you might compare the cooling sensation and crystal formation after storage in allulose and erythritol trials.

Sources and review scope

Reviewed October 22, 2026. FDA’s guidance provides the U.S. labeling context for the calorie factor and discusses the approximate sweetness comparison. The 2018 sensory paper addresses dose-response methods, not Hengliyuan sample results. The Peru project records product and packing decisions, not application performance. The syrup diagram remains a hypothetical mass-balance calculation. Human tolerance references describe their study populations and durations, not a universal intake limit. Confirm current destination-market requirements for the selected ingredient and finished product. The rounding explanation follows 21 CFR 101.9(c)(1); the partial-replacement example is arithmetic using the stated FDA factors. Cargill’s publication is supplier application commentary, not an independent comparative trial or Hengliyuan test. Do not turn animal research or a different finished product’s label into claims for a new formulation.
