Maltitol powder

A sugar alcohol (polyol) made by hydrogenating maltose; about three-quarters to nearly-as-sweet as sugar with fewer calories and a lower glycemic impact.

Should I eat Maltitol powder?

Maltitol powder is a refined sugar alcohol that mimics sugar with fewer calories and a smaller blood‑sugar spike. The main downside is digestive upset at higher intakes, so portion control is key.

Summary

Maltitol offers a middle ground between sugar and zero‑calorie sweeteners: it reduces calories and glycemic impact while preserving much of sugar’s taste and texture. Evidence supports lower post‑meal glucose and insulin responses versus sucrose and a potential tooth‑friendly advantage when it replaces sugar. However, it still affects blood sugar (especially as syrup) and can cause gas, bloating, or laxation when consumed in larger amounts. It is produced by hydrogenation using nickel catalysts; residual nickel is tightly limited, yet those with nickel sensitivity may choose to avoid it. Regulatory bodies have reviewed maltitol extensively, and JECFA’s ADI “not specified” indicates low toxicological concern at intended food uses.

Key Research Benefits

Lower glycemic impact than sugar

Crystalline maltitol has a GI around 36 and syrup around 52—both below sucrose—yielding a gentler post‑meal blood‑sugar rise.

Fewer calories than sugar

Maltitol provides about 2.4 kcal per gram versus 4 kcal per gram for table sugar.

Tooth-friendly when replacing sugars

Polyols like maltitol can help maintain tooth mineralization when they replace sugar in foods and drinks.

Key Research Risks

Gastrointestinal discomfort at higher intakes

Poor absorption can lead to gas, bloating, and laxation, especially above about 30–40 g/day in adults and lower amounts in children.

Blood sugar effect is not zero

Maltitol’s GI is moderate (≈36 for crystals; ≈52 for syrup), so it can still raise glucose and insulin compared with very low‑GI sweeteners.

Highly refined and hydrogenated

Manufactured by hydrogenating maltose over nickel catalysts; residual nickel is tightly controlled but may matter for those with nickel hypersensitivity.

Overview

What is it?

Source: Corn or wheat starch

Method: Liquefy starch, make maltose, then hydrogenate

Processing Level: 8 / 10

Why is it used?

Purpose: Bulk sweetener that replaces sugar with fewer calories and a lower glycemic response.

Commonly found in: Protein bars, Sugar-free chocolate, Chewing gum, Cookies, Ice cream

Why manufacturers choose it: Mimics sugar’s bulk and taste while cutting calories and glycemic impact.

Origin

Chemists learned to convert starch into maltose and then hydrogenate it to maltitol in the mid-late 1900s as the market sought ‘sugar-free’ candies and gums. By the 1990s, global safety bodies (JECFA/EFSA/FDA) had reviewed maltitol and similar polyols, and manufacturers widely adopted it to make chocolate, bars, and ice creams with less sugar yet similar mouthfeel.

Process: Liquefy starch, make maltose, then hydrogenate

Steps

1. Liquefy/Saccharify: Hydrolyze starch to a high-maltose syrup using enzymes (β-amylase and debranching enzymes).

2. Purify: Filter and demineralize the maltose-rich syrup.

3. Hydrogenate: React syrup with hydrogen over nickel catalyst to convert maltose → maltitol.

4. Catalyst removal: Filter to remove nickel catalyst; polish the syrup.

5. Crystallize & dry: Refine, crystallize, dry and mill into powder.

Chemicals

Hydrogen gas

Nickel (Raney Ni or supported Ni catalyst)

Food-grade enzymes (β-amylase, debranching enzyme)

pH adjusters (e.g., calcium carbonate/alkali)

Research & Safety

Research Summary

Maltitol is a sugar alcohol made by hydrogenating maltose from starch. It tastes close to sugar and supplies fewer calories (about 2.4 kcal/g vs. sugar’s 4 kcal/g). Research shows a lower post‑meal rise in blood sugar than sucrose, with a glycemic index around 36 for crystalline maltitol and about 52 for syrup. The main tradeoff is digestive tolerance: maltitol is only partly absorbed and can be fermented by gut microbes, causing gas, bloating, or laxation at higher intakes. Regulatory reviews have not identified systemic toxicity concerns; JECFA lists maltitol with an ADI “not specified,” and food‑grade specs include tight limits on residual nickel from catalysts. Overall, it can help reduce sugars and support dental health when it replaces sugar, but dosing and individual tolerance matter.

Digestive Effects

Because maltitol is incompletely absorbed in the small intestine, the unabsorbed portion pulls water into the gut and is fermented by bacteria. Common symptoms at higher intakes include gas, bloating, abdominal discomfort, and a laxative effect. Adults often tolerate around 30–40 g/day before notable symptoms, while children may experience effects at ~15 g/day. Tolerance varies by person and may improve gradually if intake is introduced slowly. People with IBS or those following a low‑FODMAP approach often find polyols trigger symptoms and may need to limit or avoid them.

Limit Consumption

Children are more likely to experience digestive symptoms at lower doses than adults, so portion size matters. People with diabetes or on very low‑carb diets should note maltitol’s moderate GI, especially in syrup form, and may want to check their post‑meal glucose response. Individuals with IBS or functional GI disorders often react to polyols and may need to avoid maltitol. Those with nickel hypersensitivity may prefer to avoid products containing maltitol because it is made using nickel catalysts, though food‑grade specs set very low residual nickel limits. Maltitol is not typically used in infant foods due to tolerance concerns; discuss any use with a pediatric clinician.

Fact Sheet

Regulatory Status

US FDA: Permitted as a ‘sugar alcohol’ in labeling; polyols generally recognized as safe when used as intended (self-affirmed GRAS widely cited).

EU Status: Approved sweetener E965(i); use per Reg. (EC) 1333/2008, often at quantum satis in reduced/no-added-sugar foods.

Codex INS: INS 965(i)

JECFA ADI: ADI ‘not specified’ (JECFA, 1993)

ESG & Sustainability

Environmental Footprint: Sourced from starch crops; hydrogenation and purification are energy- and catalyst-intensive; limited cradle-to-gate LCA data specific to maltitol.

Sustainability: Impacts tied to corn/wheat farming (fertilizer, land use); catalyst metals are recoverable; no palm-oil link.

Animal Welfare: Plant-derived; no direct animal inputs.

Carbon Footprint: No robust, ingredient-specific public LCA found; expected similar to other refined corn-derived polyols.
