TL;DR
- Amylase, xylanase and glucose oxidase are usually sold together as one compound bread improver rather than three separate additives.
- The compound is dosed per 100 kg of flour. Manufacturer sheets quote about 30–100 g per 100 kg for a full blend, and about 1.0–10 g per 100 kg for a standalone maltogenic amylase.
- The claimed outcomes are larger volume, finer crumb, softer texture, better water retention and slower staling.
- Suppliers sell improvers in both cost-optimized and high-enzyme versions, and the right one depends on how long the loaf must stay soft.
- This is a B2B-first category: bulk bags, dosing charts and trial kits are aimed at bakeries and improver formulators, with only small sachet formats reaching small shops.
Why a bakery needs more than one enzyme
Bakeries rarely have a single dough problem. Buyers online ask what bakery enzymes are for and what each one does. The general answer in creator explainers is that enzymes improve dough handling, crumb softness and shelf life, although those explainers give no numbers.
Supplier material describes the same outcomes at greater length: larger volume, fine uniform crumb, soft elastic texture, better chewability and a smoother crust. One enzyme cannot deliver all of that, so the commercial blends combine fungal α-amylase, glucose oxidase, xylanase and maltogenic amylase with ascorbic acid and a stearoyl lactylate emulsifier.
How the three enzymes divide the work
Xylanase acts on the xylan in flour and is sold in fungal or bacterial forms, often with co-enzymes in dosage packs matched to regular bread, steamed buns, frozen dough or whole wheat. Its claimed benefits are a larger loaf, finer air pores, better water retention and a longer shelf life. Xylanase is also sold blended with alpha-amylase for industrial improvers, packed in sizes suited to continuous production lines.
Fungal alpha-amylase breaks starch into sugars the yeast can use, which supports fermentation and crust color. It is easily inactivated by oven heat, so it does not keep producing dextrin into the crumb.
Glucose oxidase works on gluten. It generates hydrogen peroxide, which oxidizes thiol groups in gluten protein into disulfide bonds and so strengthens the dough network. A manufacturer sheet for a 10,000 U/g grade describes the same function as flour improvement through oxidation of gluten thiols to disulfide bonds.
Maltogenic amylase is the anti-staling partner. Its listed job is to modify starch and slow retrogradation.
Dosage and working windows
Numbers differ by format, so compare like with like. A compound blend containing all four enzymes plus ascorbic acid is specified at 30–100 g per 100 kg of flour. A standalone maltogenic amylase from the same supplier family is specified at 1.0–10 g per 100 kg of flour.
Another source puts a general bread improver at 0.5–1.0% of flour weight, with a first trial at 0.6–0.7%. An AI-search summary of a bakery glucose oxidase quotes 2–40 g per tonne of flour, sold in 1 kg bags.
Our own listed rates for single enzymes sit at the low end of these ranges: 2–4 g per tonne of flour for a 100,000 U/g fungal amylase. Xylanase grades are listed at 5–10 g per tonne (5,500 U/g) and 10–20 g per tonne (12,500 U/g).
The working windows overlap enough to run together. A compound bread-improvement blend is documented as working at pH 3.0–7.0 (optimum 5.5–6.5) and 25–70 °C (optimum 40–50 °C). A glucose oxidase sheet gives pH 3.5–6.5 (optimum 5.0–5.5), 40–60 °C (optimum 50–55 °C) and an application rate of 0.1–0.3%. A standalone maltogenic amylase sheet gives pH 4.0–7.0 (optimum 4.5–5.5) and 30–80 °C (optimum 55–65 °C).
The pH windows of the three enzymes overlap comfortably with typical dough pH, so a blend does not need a pH adjustment beyond normal baking practice. Two of the sheets list an optimum temperature above where dough is normally mixed and proofed, so those figures describe the enzyme’s peak activity in isolation, not what it does inside a working dough — check a specific product’s data before assuming full activity at proofing temperature.
What the manufacturers and buyers are actually saying
Two improver tiers are offered. The first is a standard, low-enzyme blend that is cost-optimized for fresh-baked items with a short shelf life. The second is a high-enzyme multi-enzyme blend for industrial toast, frozen dough and long-shelf packaged bread. The selling point of the high-enzyme tier is that softness lasts longer than the usual one to two days, which suppliers link to fewer returns and less waste.
Suppliers also publish cake and steamed-bun versions. Steamed-bun sellers target a different outcome: a bigger bun, a bright surface and a soft interior. One recurring theme across supplier sources is that the printed range is a starting point, not a fixed answer — the exact number for your own flour and process has to be found by trial.
Limitations and trade-offs
No per-enzyme optimum for the combined system is published in our data, and each figure above comes from a different supplier sheet with its own unit definition. Activity units are not comparable across sheets. For example, our xylanase listings define a unit at 50 °C and pH 5.0, while other suppliers may use different assay conditions.
As general industry practice rather than a figure from any one sheet, a higher-enzyme-content blend is priced for what it does, not what it costs to make — it only pays off where the loaf genuinely needs to stay soft for days, not for short-shelf-life fresh bakes. Adding more is not a free fix. Suppliers give a range rather than a “more is better” rule, and what happens to dough beyond that range has to be found by trial. Claims such as larger volume or longer softness are supplier claims, not results we have measured.
Trial design and validation
A starter approach from the supplier side is a kit per bread type (toast, pastry, hard breads, cakes) with dosage cards, SOP templates and first-trial parameters for mid-size bakeries scaling up. Follow that logic: fix the flour, water and mixing time, then run the blend at the low, middle and high end of its range.
Judge volume, crumb structure, handling and softness after storage. The softness check matters because the anti-staling claim is about days, not hours. Repeat with each flour lot you buy, since the optimum depends on your conditions.
Is this retail or B2B?
It is overwhelmingly B2B. Bulk compound enzyme blends are sold by industry (baking, feed, starch, protein hydrolysis) with recommended dosages and parameters. Improver blends ship in 25 kg bags for factory use.
The nearest thing to a small-buyer format is a starter kit with a simple dosing chart for small bakeries. Another is a pre-portioned 1 g sachet sized for one day’s steamed-bun batch. Even the small-bakery purchasing advice for glucose oxidase points to 1 kg bags, not household packs.

FAQ
What do bakery enzymes actually do? They are added mainly to improve dough handling, crumb softness and shelf life, though general explainers rarely give dosing numbers.
How much improver should I add, and what if I add too much? Published ranges run from 30–100 g per 100 kg of flour for a full blend to 0.5–1.0% of flour weight, with a first trial at 0.6–0.7%.
The sources do not quantify the over-dose effect. They only say to test within the supplier range.
Can a small bakery buy these, or is it industrial only? Small formats exist, such as dosing-chart starter kits and 1 g sachets. Most supply is still bulk-bag B2B.
