Rare sugars and enzymatic sweeteners
Enzymatic epimerization turns commodity starch and fructose into allulose and tagatose — naturally occurring low-calorie sugars with sugar-like taste — while a separate fermentation route delivers stevia-derived sweeteners, moving allulose from 'unicorn ingredient' to commercial reality.
1 · What it gives
Rare sugars and enzymatic sweeteners use engineered enzymes — epimerases in particular — to convert commodity fructose or starch into low-calorie monosaccharides such as allulose (D-psicose) and tagatose that occur naturally in small quantities but taste and behave like ordinary sugar. Ingredion holds a patent describing epimerase-based conversion of fructose to allulose, and organic allulose has reportedly “crossed the line from industry legend to commercial reality” as a clean-label, reduced-sugar formulation ingredient. Bonumose produces high-volume, naturally occurring monosaccharides from commodity starch and sugar feedstocks using innovative enzyme combinations, and partnered with protein-engineering firm Allozymes in 2025 to accelerate new enzyme development. A parallel, non-sugar sweetener route uses fermentation rather than enzymatic conversion: Tate & Lyle and Manus Bio launched Yume, a stevia-derived sweetener brand, as allulose and tagatose gain prominence alongside it in the broader better-tasting, healthier-sweetener market.
Key directions of rare sugars and enzymatic sweeteners:
- Enzymatic epimerization of commodity sugars (Enzymatic Epimerization of Commodity Sugars): epimerase enzymes convert abundant fructose into rare sugars like allulose without a full fermentation process.
- High-volume rare-monosaccharide production (High-Volume Rare- Monosaccharide Production): enzyme-combination processes converting starch/sugar feedstocks into naturally occurring monosaccharides at commercial scale rather than trace extraction.
- Fermentation-derived non-sugar sweeteners (Fermentation-Derived Non-Sugar Sweeteners): stevia-derived or other non-sugar sweetener molecules produced via precision fermentation as a complementary category to enzymatic rare sugars.
- Clean-label reduced-sugar reformulation (Clean-Label Reduced-Sugar Reformulation): food brands reformulating existing sugar-sweetened products around allulose/tagatose to cut caloric sugar while keeping a clean ingredient label.

Information, not legal advice — confirm the procedure for your product. (2026-10-06)
United States
The US hosts an enzyme-engineering rare-sugar originator and the ingredient giant holding a core epimerization patent.
enzyme-engineering partnerships, epimerase patents, commercial-reality allulose reformulation#
- Bonumose: produces high-volume, naturally occurring monosaccharides from commodity starch and sugar using innovative enzyme combinations, and partnered with Allozymes in 2025 to accelerate enzyme innovation.
- Ingredion: holds a patent on epimerase-based fructose-to-allulose conversion, positioning it among the core enzymatic-conversion IP holders in the category.
European Union
The UK-headquartered ingredient major anchors the region’s rare-sugar and adjacent fermentation-sweetener activity.
stevia-derived sweetener brand launch, allulose/tagatose market growth, clean-label reformulation demand#
- Tate & Lyle: launched Yume, a stevia-derived sweetener brand, in partnership with fermentation specialist Manus Bio, alongside broader market growth in allulose and tagatose as consumers seek healthier, better-tasting sweeteners.
- Market-growth signal: industry data cited in trade coverage identifies allulose and tagatose as gaining prominence specifically because they combine health positioning with genuine sugar-like taste, unlike many earlier sugar substitutes.
China
Public information on a dedicated Chinese rare-sugar/enzymatic-sweetener originator at the scale of the US/EU leaders was not confirmed in this pass; the section stays at the policy level.
no confirmed flagship originator, regional distribution channels, adjacent ingredient trade activity#
- No confirmed flagship originator: neither of the two East Asian candidates investigated in this pass returned a source directly confirming a rare-sugar/enzymatic-sweetener production program.
- Regional distribution activity: bulk allulose supply listings circulate through Chinese ingredient-trading platforms, reflecting active regional trade in the ingredient without a confirmed domestic originator.
- Adjacent academic research: metabolic-engineering research on allulose production (e.g., via Corynebacterium glutamicum) is active in the wider literature, ahead of a confirmed commercial-scale originator in this specific pass.

7 · Tech stack & innovations
The stack converts abundant commodity sugars into rare, low-calorie equivalents at industrial volume.
- Epimerase-driven fructose conversion (Epimerase-Driven Fructose Conversion):
- epimerase enzymes rearrange fructose’s molecular structure into allulose, a rare sugar occurring only in trace amounts in nature.
- case: Ingredion’s patented process describes exactly this epimerase-based fructose-to-allulose conversion route.
- Multi-enzyme combination cascades (Multi-Enzyme Combination Cascades):
- combinations of enzymes convert starch or sugar feedstocks into naturally occurring monosaccharides at high volume rather than trace extraction.
- case: Bonumose’s enzyme-combination process is the basis of its high-volume rare-monosaccharide production.
- Fermentation-based non-sugar sweetener production (Fermentation-Based Non-Sugar Sweetener Production):
- a host organism is engineered to produce a non-sugar sweetener molecule (e.g., a stevia glycoside) via fermentation rather than enzymatic sugar conversion.
- case: Manus Bio’s fermentation platform underlies the Yume stevia-derived sweetener brand launched with Tate & Lyle.
