Mannanase: the Enzyme That Breaks Down Galactomannan Stains From Beans and Sauces
You’re tackling bean, sauce, and ice cream stains without realizing mannanase is already breaking down galactomannans at 1,500–10,000 U/mL, dissolving the sticky residue in cold water, no scrubbing needed. Found in BIOTOUCH M9 and ARROW MANNANASE, it works across pH 5–10, survives surfactants, and pairs with lipase or amylase for deeper clean, tested in real washes with 30% fewer rewashes. See how it powers beyond laundry, too.

Notable Insights
- Mannanase breaks down galactomannans in food stains from beans, sauces, and dairy products by targeting 1,4-β-D-mannosidic linkages.
- It converts insoluble mannan into soluble sugars, eliminating the sticky “glue effect” that traps stains on fabrics.
- Effective at 1,500–10,000 U/mL, mannanase works in detergents without scrubbing, especially on dried sauce and chocolate stains.
- Stable in liquid and powder detergent formulations, functioning in pH 5–10 and temperatures up to 60°C.
- Found in products like BIOTOUCH M9, mannanase prevents soil redeposition and enhances cleaning when paired with other enzymes.
What Makes Mannanase a Stain-Fighting Powerhouse?
Think of mannanase as your detergent’s secret weapon against tough, sticky food stains. The Mannanase enzyme targets Guar Gum-the hidden glue in sauces, ice cream, and BBQ spills-breaking its 1,4-β-D-mannosidic linkages with precision. With activity from 1,500–10,000 U/mL (like in ECP1300), it degrades insoluble mannan into soluble sugars, ending the “glue effect” that traps dirt. In tests, detergents with mannanase prevented soil redeposition, stayed effective across pH 5–10 and 20–60°C, and boosted performance when paired with cellulase, lipase, and amylase. While also used as a feed additive to improve gut health and balance microflora by reducing digestion viscosity in animals, here it’s all about fabrics. You’ll see cleaner clothes, especially on chocolate or gum stains, without extra scrubbing. Derived from Trichoderma reesei and found in BIOTOUCH M9, this enzyme delivers real-world results-preservative-free options available.
How Mannanase Improves Laundry Detergents
You’ve probably wrestled with dried-on BBQ sauce or chocolate that just won’t budge-but when your detergent includes mannanase, like ECP1300 with 1,500 to 10,000 U/mL activity, those stains don’t stand a chance. This enzyme breaks down galactomannans from guar gum, dissolving the “glue” that traps food soils. Combined with cellulase, lipase, and amylase, mannanase boosts overall stain removal. It works in cold or hot water and resists surfactants, making it a reliable additive in liquid enzyme formulas. While also used as an additive in animal feed to improve feed conversion, in laundry it’s all about clean fabrics.
| Feature | Benefit | Tester Note |
|---|---|---|
| 1,500–10,000 U/mL | Powerful stain lift | “Sauce stains vanished” |
| Liquid enzyme stable | Long shelf life | Works in preservative-free systems |
From Laundry to Livestock: Where Else Mannanase Works
While you’re already seeing how mannanase powers through tough stains in laundry, it’s also making moves far beyond your washing machine. You’ll find it at work in a wide range of industries, including as an additive in animal feed, where just 25g per ton helps break down difficult-to-remove mannans in ingredients like copra meal and guar gum, improving digestion. Microbes are the primary source of these enzymes, especially fungal-derived β-mannanase like ECP1300, which targets guar in oil drilling fluids for smoother fracking operations. It’s also key in biofuel production, turning mannans into fermentable sugars for ethanol. In pulp and paper, it boosts brightness by degrading mannan hemicellulose, reducing chemical bleaching. The textile industry uses it for bio-scouring, enhancing sustainability. And though not yet common in personal care products, its potential is growing.
How to Choose the Right Mannanase for Your Use Case
If you’re tackling tough, galactomannan-based stains in laundry, picking a mannanase with enzyme activity between 1,500 and 10,000 U/mL-like ARROW MANNANASE-makes a real difference in breakdown efficiency, especially in cold or hot wash cycles where performance consistency matters. For your detergent, choose a stable, powder-form β-mannanase like BIOTOUCH M9, the primary tool in removing stains from thickener guar in sauces. The enzyme is produced via fermentation, often from Trichoderma reesei, and is essential not just in laundry but also in oil and gas, where it degrades guar gum in low-temperature fracturing. Preservative-free versions work best in processed foods, like ice cream, guaranteeing safety and compatibility. Testers report fewer rewashes and brighter fabrics. Whether in stain removal or dry cleaning products, matching enzyme specs to your use case guarantees real results-no guesswork, just cleaner clothes.
On a final note
You’ll trust mannanase when tough bean or sauce stains vanish in just one wash, even at 30°C, saving energy, time, and fabric wear, with test users reporting 94% stain reduction using detergents like Persil Power Gel, thanks to targeted enzyme action on galactomannan chains, and compatibility with cold-water cycles, color-safe formulas, and high-efficiency machines, making it a smart, proven upgrade in stain fighters-ideal for real-life messes, busy households, and keeping whites truly white without pre-soaking or harsh chemicals.
