Clean-label and enzyme-only improvers: replacing DATEM, SSL and L-cysteine without losing performance

<!-- image: img-clean-label-bread-comparison -->

Why bakers want to remove E-number emulsifiers

Consumer panels across Europe consistently show that shoppers prefer shorter ingredient lists with recognisable ingredients. In the UK, the "free from artificial additives" positioning is a frequent purchase driver in premium and artisan bread segments. In Poland, Turkey and Arab markets — key audiences for this platform — the trend toward clean-label bakery products is accelerating, driven by foodservice buyers, private-label briefs and health-conscious retail consumers.

For the professional baker, the challenge is clear: DATEM (E472e), SSL (E481) and L-cysteine (E920) exist in improvers because they do specific, difficult jobs. Removing them without understanding what replaces them causes bake failures. This article explains the replacement strategy in practical terms.

Full mechanism descriptions of each conventional emulsifier and additive are in the companion articles [A3-emulsifiers-in-bread] and [A3-ascorbic-acid-oxidants-reductants]. This article focuses on the replacement map and the products available from the Domson catalogue.

What the conventional additives do — a brief recap

DATEM (E472e) strengthens gluten networks. Its tartaric acid groups bond ionically to glutenin proteins, reinforcing the protein web, retaining more CO₂ during fermentation and giving the dough tolerance against flour variability. Typical effective dosage in dough: 0.1–0.5% of flour weight. [src-051] In the Domson catalogue, DATEM is the primary active in Puratos S500 SG (up to 2% product dosage), Puratos S500 Sense SG (10–20% DATEM in product), and Puratos Tigris SG 2% (10–20% DATEM in product). [ss-puratos-s500-sg, ss-puratos-s500-sense, ss-puratos-tigris-2]

SSL (E481) does two distinct jobs: it strengthens gluten (like DATEM) and it forms inclusion complexes with amylose starch chains, slowing retrogradation and keeping the crumb soft for longer. Typical dosage: 0.1–0.5% of flour weight. EU maximum: 3 g/kg in finished bread (EU Regulation EC 1333/2008, Category 07.1). [src-051, src-EU-1333-2008]

Regulatory compliance flag (human review required): At the upper end of this dosage range (0.5% SSL on flour), the estimated SSL level in finished bread is approximately 3.4–3.5 g/kg (assuming typical 65% hydration and 14% baking loss), which approaches or may exceed the EU maximum of 3 g/kg for E481 in bread (Category 07.1). Before specifying SSL dosages at or near 0.5% on flour in any customer-facing formulation guidance, verify the delivered SSL level in the specific finished bread formula and check against the current consolidated Annex II of EU Regulation 1333/2008. [src-EU-1333-2008]

In the catalogue, SSL is the primary active in IREKS Crumb Softener (1.5% dosage), IREKS Toast & Buns / Super Toast (2% dosage), and appears alongside DATEM and MDG in IREKS Soft Roll 7 (7% dosage) and IREKS Voltex (1–2% dosage). [ss-ireks-softy, ss-ireks-supertoast, ss-ireks-softroll7, ss-ireks-voltex]

L-cysteine (E920) is a dough reductant. It cleaves disulphide bonds in glutenin, reducing dough elasticity and enabling sheeting, automated forming and shorter mixing times — particularly valuable for crackers, pizza bases and very strong (high-protein) flour formulations. Dosage: approximately 10–75 ppm in dough. [src-061]

The enzyme toolkit: what each enzyme replaces

<!-- image: img-enzyme-replacement-map -->

Enzymes are proteins produced by microorganisms (bacteria, fungi). In EU and UK law, enzymes used in bread are classified as processing aids under Regulation (EC) No 1332/2008 when they have no significant technological effect in the finished baked product — meaning the finished bread does not need to declare them in the consumer ingredient list. This is the legal mechanism that makes enzyme-only "clean-label" bread possible. [src-EU-1332-2008]

Lipase and phospholipase — replacing DATEM

<!-- image: img-enzyme-mechanism-lipase -->

Phospholipase A1 and A2 enzymes act on naturally occurring phospholipids in wheat flour, producing lyso-phosphatidylcholine (lyso-PC). Lyso-PC is an amphiphilic molecule structurally analogous to DATEM: it stabilises gas cells at the gluten-water-gas interface, reinforces the gluten network, and improves dough tolerance and loaf volume. [src-053]

Natural wheat flour contains approximately 0.5–1% total lipid, of which roughly 25% is polar phospholipids. Phospholipase generates lyso-PC in situ during mixing, avoiding the need to add a pre-formed emulsifier. The enzyme is then inactivated during baking, leaving lyso-PC residues that contribute emulsifying activity without triggering an additive declaration requirement.

Performance relative to DATEM: independent research (Lesaffre, src-056) and industry experience (AB Enzymes src-052) indicate that lipase-generated lyso-PC can replicate most of DATEM's dough-strengthening and volume-increasing effects in standard white and wholemeal bread. For very strong flours or high-speed mixing lines, supplementation with vital wheat gluten (VWG) at 1–2% on flour is typically recommended.

Xylanase — machinability and water management

Xylanase degrades arabinoxylans (AX), the major hemicellulose fraction of wheat flour. AX binds significant amounts of water; xylanase hydrolysis releases this bound water into the gluten network, improving dough extensibility, reducing stickiness and enabling better water distribution. [src-048, src-053]

Key practical effects: less dough adherence to moulder, divider and sheeter; more consistent dough piece weight; improved crumb structure uniformity. Xylanase does not replicate SSL's anti-staling function — it acts during mixing and fermentation, not in the baked product.

Glucose oxidase (GOX) — oxidative gluten strengthening

Glucose oxidase converts glucose to gluconolactone, generating hydrogen peroxide (H₂O₂) as a by-product. H₂O₂ oxidises glutenin thiol (SH) groups, forming additional disulphide (S-S) crosslinks in the gluten network — the same structural outcome as ascorbic acid (E300) but via a different route. [src-053]

GOX strengthens the gluten network without any additive declaration. Used in combination with lipase, it can substitute for the main volume-enhancing functions of DATEM. Typical dosage: 2–30 ppm enzyme protein. [src-053] This is a single-source range — use as indicative only; verify with the enzyme supplier before formulation sign-off.

Maltogenic amylase — anti-staling without SSL or MDG

<!-- image: img-maltogenic-amylase-antistaling -->

Thermostable maltogenic amylase (produced from Bacillus stearothermophilus or related organisms) hydrolyses amylose and amylopectin side chains during baking and post-baking cooling, producing shorter oligosaccharides that are less able to recrystallise. This delays starch retrogradation — the primary cause of bread crumb hardening — keeping the crumb soft for longer. [src-048, src-053]

SSL and MDG (E471) achieve a similar delay by a different mechanism: they form helical inclusion complexes with amylose chains, physically preventing recrystallisation. Maltogenic amylase shortens the chains before they can crystallise; the net effect on crumb softness is comparable, though the precise shelf-life outcome varies by formula and flour.

One academic source (IntechOpen, src-053) reports maltogenic amylase-treated breads maintaining softness for 5–7 days versus 2–3 days for untreated control. This figure is single-source and should be treated as indicative. Actual results depend on the flour system, fermentation conditions and packaging. [c20]

Protease — replacing L-cysteine for dough relaxation

Fungal proteases (optimum pH approximately 4–5) partially hydrolyse gluten proteins, reducing dough elasticity and increasing extensibility. This replicates L-cysteine's disulphide-bond cleavage effect via a different — and slower — mechanism. [src-048, src-061]

Critical caution (food safety relevance): Protease over-dose leads to irreversible gluten destruction: sticky, inextensible dough that cannot be recovered. L-cysteine's action is more rapid and dose-predictable. When switching from L-cysteine to protease, begin at the lowest possible dosage and conduct a minimum of five bake trials before fixing a formula. Reduce improver dosage in trials rather than the product's formula rate if the product is a pre-blended improver.

Alternative: inactivated (killed) baker's yeast contains glutathione (GSH) — a tripeptide that cleaves disulphide bonds via thiol-disulphide exchange, comparable to L-cysteine but gentler in action. It is declared simply as "yeast" on an ingredient list. Typical dosage: approximately 0.1–0.5% on flour weight (single-source BAKERpedia, confidence: low). [src-061, c27]

Transglutaminase — gluten crosslinking without emulsifiers

Transglutaminase (TGase) forms covalent isopeptide bonds between glutamine and lysine residues in gluten proteins, crosslinking the network directly. This does not replicate DATEM's ionic mechanism but produces similar macroscopic outcomes: improved loaf volume, dough tolerance and machinability. [src-053] TGase does not appear as a declared ingredient in the Domson catalogue's current bread improver range but is available from specialist enzyme suppliers and is a processing aid under EU/UK law.

Vital wheat gluten: the structural anchor for clean-label formulas

<!-- image: img-vwg-gluten-network -->

When emulsifiers are removed from a bread formula, the gluten network must be strong enough on its own to retain fermentation gas and support loaf volume. Vital wheat gluten (VWG) achieves this by directly increasing the protein content of the dough.

Beneo BeneoPro VWG 75 is the VWG product in the Domson catalogue. Key specifications from the first-party spec sheet: [ss-beneo-vwg75, c9, c10, c11]

| Parameter | Specification | |-----------|---------------| | Protein (N×5.7) | Minimum 75% dry matter | | Protein (N×6.25 equivalent) | Minimum 82% dry matter | | Moisture | Maximum 8% | | Fat | Maximum 2% | | Ash | Maximum 1% | | Water binding capacity | Approximately 140–170 g/100 g (AACC 56-30) | | Shelf life | 36 months (<60% RH, <20°C) | | Certifications | Kosher, Halal, vegetarian, vegan | | Allergens | Contains wheat gluten only; no other declared allergens |

How to use VWG in clean-label reformulation:

• Add 1–2% VWG on flour weight when switching a white or wholemeal bread from a DATEM-containing improver to an enzyme-only system.
• Add 2–4% VWG for high-fibre (wholemeal, multigrain) breads where bran dilutes native gluten.
• VWG absorbs approximately 140–170% of its weight in water [ss-beneo-vwg75, c10] — increase dough water absorption by approximately 1.2–1.5 kg water per kg VWG added.
• Mix VWG into dry flour before water addition to ensure full hydration.
• Dosage range from BAKERpedia (src-057): 1–12% of flour weight (1–4% for most yeast-raised doughs; up to 12% for high-fibre applications). First-party manufacturer context suggests 1–5% for standard applications. [c26]

VWG on the bread label: VWG is a natural food ingredient, not an additive. It appears in the ingredient list as "wheat gluten" — a recognisable, non-intimidating term that supports clean-label positioning.

Enzyme-active soya flour: natural oxidant and bleacher

Cereform Breadsoy (enzyme-active full-fat soya flour from AB Mauri) is the enzyme-active soya flour in the Domson catalogue. [ss-cereform-breadsoy]

Breadsoy retains active lipoxygenase enzyme, which oxidises unsaturated fatty acids in the flour, generating lipid peroxides that:

1. Bleach carotenoid pigments in wheat flour — producing a whiter crumb without chemical bleaching agents.
2. Mildly strengthen gluten via oxidation of SH groups.

Key specifications: [ss-cereform-breadsoy, c25]

• 100% enzyme-active full-fat soya flour (Non-GM IP Canadian and UK beans)
• Protein: 35.2 g/100g; Fat: 17.4 g/100g; Fibre (AOAC): 15.3 g/100g
• Moisture: 6–11%; shelf life: 270 days (storage 10–25°C)

Important allergen note (flag for human review): Cereform Breadsoy is 100% soya flour. Soya is a major allergen under EU Regulation 1169/2011 and must be declared in the finished bread ingredient list as "soya flour" or equivalent. This is not a processing aid — it is an ingredient. A bread produced with Breadsoy cannot claim to be "free from" soya. If allergen-free clean-label bread is required, do not use soya flour — rely on the enzyme system alone (lipase, xylanase, GOX from non-soya sources).

Clean-label catalogue products: Zeelandia's enzyme-only range

Zeelandia Gamma GP — general-purpose enzyme-only bread improver

<!-- image: img-gamma-gp-product -->

Gamma GP is the benchmark enzyme-only bread improver for white and wholemeal bread production. Its complete ingredient declaration (from spec sheet): WHEAT flour, vegetable oil (rapeseed), flour treatment agent E300, enzyme [WHEAT]. No emulsifiers. No soya. No milk. [ss-zeelandia-gamma-gp]

Dosage by application (first-party spec sheet): [c6]

| Application | Dosage (% on flour) | |-------------|---------------------| | White tin bread | 0.5–0.75% | | Bloomers | 1% | | Soft rolls (add Zedomals liquid for extended softness) | 1.5% | | Crusty rolls | 2% | | Wholemeal breads | 2% |

Shelf life: 12 months from manufacture. [c21]

Allergen status: Contains WHEAT (as carrier flour and enzyme). Cross-contamination risk on the production line: Rye, Barley, Oats, Spelt, Egg, Soya, Milk, Sesame, Lupin. If the bakery's finished product must be declared free from any of these allergens, confirm directly with Zeelandia. [ss-zeelandia-gamma-gp]

What the bread label reads: A white tin loaf using only Gamma GP as the improver (with flour, water, yeast, salt, rapeseed oil) can declare: Wheat flour (with calcium carbonate, iron, niacin, thiamin), water, yeast, salt, rapeseed oil, ascorbic acid (E300), enzyme. The E300 is declared because it is a food additive (flour treatment agent), not a processing aid. Declaring it as "ascorbic acid" rather than "E300" removes the E-number. The enzyme does not need to appear on the finished bread label under EU/UK processing aid rules.

Performance note: Gamma GP's spec sheet recommends adding Zedomals (a Zeelandia liquid softener) alongside Gamma GP for soft roll production. This indicates that the enzyme system alone does not fully replicate the crumb-softening effect of SSL or MDG in soft, enriched applications. For standard tin bread and crusty rolls, no supplement is needed.

---

Zeelandia Optimax Free — enzyme-only rye and mixed bread improver (with VWG)

Optimax Free is designed for breads where rye flour is a major component. Its composition (from spec sheet): WHEAT gluten (50%), RYE flour (39%), potato starch (10%), flour treatment agent E300 (<1%) from maize, WHEAT flour (<1%), enzyme (<1%) from Netherlands. [ss-zeelandia-optimax-free]

No emulsifiers. The 50% wheat gluten content makes this product function differently from Gamma GP: at a 1.67% dosage, approximately 0.84% of the flour weight is contributed as pure vital wheat gluten. This structural protein addition compensates for rye flour's absence of gluten-forming proteins. The enzyme (Netherlands origin) handles arabinoxylan management and fermentation.

Application recipe (from spec sheet): [c7]

• 1.0 kg wheat flour type 850 + 5.0 kg rye flour type 720 = 6.0 kg total flour
• 0.1 kg Optimax Free = 1.67% on total flour
• 6.4 kg rye sourdough + 0.23 kg salt + 0.25 kg yeast + 5.6 kg water

Process: Mix 8 min slow + 2 min fast. Dough temperature approximately 28°C. First proof 15 min. Divide, pan. Final proof 50 min. Bake 250→230°C with steam for first 5 min. Baking time 45 min.

Shelf life: 180 days (6 months). [c22] Shorter than Gamma GP due to the rye flour and high-protein gluten content.

Allergen status: Contains wheat gluten and rye (both as ingredients). Cross-contamination possible: barley, oat, spelt, egg, soya, milk, sesame.

Zeelandia Rye Stabil Free (Rye Stabil Improver) — high-gluten enzyme system for rye-wheat bread

Rye Stabil Free is the highest-gluten enzyme improver in this range, optimised for mixed rye-wheat and predominantly rye breads. Composition (from spec sheet): WHEAT gluten (78%), pregelatinised WHEAT flour (20%), WHEAT flour (1%), flour treatment agent E300 (1%), enzymes (<1%) from Finland and Japan. [ss-zeelandia-rye-stabil-free]

The 78% gluten content means this product is functionally a concentrated gluten carrier with enzyme support. At the stated recipe dosage of 2.78% on total flour, approximately 2.2% of the flour weight is contributed as pure vital wheat gluten. The pregelatinised flour (20% of product) acts as a binding and consistency agent, improving dough handling.

Nutritional values per 100g product (from spec sheet): [c28] Protein 60.8g, fat 5.0g, carbohydrate 23.0g, fibre 1.8g, energy 386 kcal. The high protein value is consistent with the 78% gluten composition.

Application recipe (from spec sheet): [c8]

• 3.0 kg wheat flour type 850 + 4.2 kg rye flour type 720 = 7.2 kg total flour
• 0.2 kg Rye Stabil Free = 2.78% on total flour
• 4.6 kg rye sourdough + 0.22 kg salt + 0.2 kg yeast + 5.8 kg water

Process: Mix 7 min slow + 3 min fast. Dough temperature 27–29°C. First proof 15–20 min. Divide into 0.8 kg pieces, shape, place on boards or in baskets. Final proof approximately 45 min. Bake 250→230°C with steam, approximately 40 min.

Shelf life: 270 days (9 months). [c23]

Product identity note: The Domson catalogue lists this product as "Rye Stabil Improver 25 kg" (prod_01KJABDMBVFTJPDSHSNJEWYASY); the spec sheet reads "Rye Stabil Free". Verify with Zeelandia that the currently stocked product is the enzyme-only "Free" formulation before positioning it as E-number-emulsifier-free to customers.

Conventional comparators: what you are reformulating away from

The following products from the catalogue contain declared emulsifier E-numbers and are listed here for comparison and to help bakers identify what needs to be replaced when switching. Full details are in [A3-emulsifiers-in-bread].

Puratos S500 SG (up to 2% on flour): Contains E472e (DATEM) and E516 (calcium sulphate). Primary DATEM-based improver. Ascorbic acid 0.9–1.1% in product. [ss-puratos-s500-sg, c12]

Puratos S500 Sense SG (typically 0.5–1% on flour): Contains E472e (DATEM) at 10–20% of product, fermented rye flour. Ascorbic acid 0.67% ±10% in product. [ss-puratos-s500-sense, c13]

Puratos Tigris SG 2% (2% on flour): Contains E472e (DATEM) at 10–20% of product, dextrose. Ascorbic acid 1% ±10% in product. [ss-puratos-tigris-2, c14, c30]

IREKS Voltex (1–2% on flour): Contains E472e (DATEM) and E481 (SSL). Soya flour as carrier — bread must declare both emulsifiers and soya allergen. [ss-ireks-voltex, c16]

IREKS Crumb Softener (Softy) (1.5% on flour): Contains E481 (SSL) as primary active. Wheat flour carrier, no soya. [ss-ireks-softy, c17]

Allergen flag (human review required): The IREKS Softy spec sheet lists cross-contamination risk for lupin and mustard in addition to egg, soya, milk, and sesame. Both lupin and mustard are major allergens under EU Regulation 1169/2011 (Annex II) and UK food law. Lupin in particular is frequently under-declared in bakery. Any bread produced with this improver may require "may contain lupin" and "may contain mustard" declarations if allergen risk is not mitigated through segregation. Verify with IREKS and conduct a formal allergen risk assessment before any customer-facing allergen communication. [ss-ireks-softy]

IREKS Toast & Buns / Super Toast (2% on flour): Contains E481 (SSL). Soya flour carrier — bread must declare SSL and soya allergen. [ss-ireks-supertoast, c18]

IREKS Soft Roll 7 (7% on flour): Contains E481 (SSL) + E471 (MDG) + E472e (DATEM), plus soya flour and whey powder (milk). Richest emulsifier profile in the catalogue — a complex improver that contributes sugar, salt and fat as well as emulsifiers. Bread must declare three emulsifiers plus soya and milk allergens. [ss-ireks-softroll7, c15]

Salt content and HFSS flag (human review required): The IREKS Soft Roll 7 spec sheet declares a salt content of 22.4 g/100g in the product. At the stated 7% dosage, this improver alone contributes approximately 1.6 g salt per 100g flour — exceeding the UK Food Standards Agency voluntary salt-reduction target for bread (≤1.0 g/100g finished bread from 2024) before any baker's salt addition. Formulas using Soft Roll 7 will substantially exceed FSA voluntary salt targets and may be affected by HFSS marketing regulations. Communicate salt contribution clearly when recommending this product to customers, and ensure finished product nutritional analysis is conducted before launch. [ss-ireks-softroll7]

EU and UK regulatory rules: what "clean label" means legally

The additive–processing aid distinction

| Category | Legal definition | Declared on bread label? | E-number? | |----------|-----------------|--------------------------|-----------| | Food additive | Intentionally added substance with technological function that remains active in the finished food | YES (EU Reg. 1169/2011) | Usually yes | | Processing aid | Substance used in processing; no significant technological effect in the finished food; present only as unavoidable residue | NO | No |

Under EU Regulation (EC) No 1332/2008 (the food enzymes regulation), enzymes used in bread that have no significant technological effect in the finished baked product are processing aids — they do not need to be declared on the consumer ingredient list. [src-EU-1332-2008] The UK retained this classification post-Brexit (UK Retained Regulation 2008/1332). [src-UK-FSA]

DATEM (E472e), SSL (E481), CSL (E482) and L-cysteine (E920) are food additives listed in EU Regulation (EC) No 1333/2008, Annex II. They must be declared in finished bread ingredient lists. [src-EU-1333-2008]

Ascorbic acid (E300): the residual E-number

Ascorbic acid is a food additive (flour treatment agent), not a processing aid. It remains in a small amount in baked bread and must be declared. All clean-label improvers in the Domson catalogue — including Gamma GP, Optimax Free and Rye Stabil Free — contain E300. It appears in the bread ingredient list either as "E300" or as "ascorbic acid". Declaring it by name ("ascorbic acid") removes the E-number from the label without changing the substance; this is standard practice for clean-label bread positioning.

Labelling a bread made with Gamma GP

A white tin loaf using Zeelandia Gamma GP (0.75% dosage) as the sole improver, with standard ingredients, can legitimately carry:

INGREDIENTS: Wheat flour (with calcium carbonate, iron, niacin, thiamin), water, yeast, salt, rapeseed oil, ascorbic acid, enzyme.

No E-number emulsifiers. The enzyme is not declared (processing aid exemption). Ascorbic acid is declared by name rather than E-number. This satisfies both EU Regulation 1169/2011 and UK food labelling requirements.

What "E-number-free" means and does not mean

"E-number-free" is a marketing claim, not a legal food category. It means the ingredient list contains no E-codes. Declaring ascorbic acid by name rather than E300 achieves this without removing the substance. However, if the bakery wishes to completely remove ascorbic acid (making the formula enzyme-only with zero E-numbers), a reformulation discussion with Zeelandia is required — some applications without any ascorbic acid may show reduced volume.

Reformulation protocol: switching from conventional to enzyme-only

Step 1: identify what your current improver delivers

Review the declared ingredient list of your current improver:

• Does it contain E472e (DATEM) as primary active? → Volume and dough strengthening is the primary function. Replace with a lipase-containing enzyme improver or with Gamma GP + VWG supplementation.
• Does it contain E481 (SSL) as primary active? → Anti-staling and crumb softness are key. Replace with maltogenic amylase-containing enzyme improver, supplemented with liquid softener for extended-life products.
• Does it contain E920 (L-cysteine)? → Dough relaxation is needed. Switch to inactivated yeast or protease-containing enzyme system.
• Does it contain soya flour (as allergen)? → The current product already contributes soya to the bread label. Switching to Gamma GP removes this allergen declaration.

Step 2: calculate the effective active level you are replacing

Using Puratos Tigris SG 2% as an example: DATEM content in product = 10–20% (c30). At 2% product dosage, effective DATEM in dough = 0.2–0.4% of flour weight. This is within the typical dosage range [c1]. Your enzyme replacement (lipase + xylanase combination) must deliver comparable gluten network reinforcement at that level.

Step 3: trial the enzyme-only improver at the midpoint of its recommended range

Start at the midpoint of the spec-sheet dosage range (e.g. 1.25% for Gamma GP where the range for your application is 1–1.5%). Run three identical bake tests. Assess:

• Loaf volume (compare to conventional benchmark — target ±5%)
• Crust colour and sheen
• Crumb structure and cell uniformity
• Day 1 crumb softness and resilience
• Day 3 and Day 5 crumb hardness (staling rate)

Step 4: adjust dosage or add supplementary ingredients

If volume is insufficient: increase enzyme improver by 0.25% increments; add VWG at 1% on flour. If staling is faster: add maltogenic amylase preparation; check water activity of baked product. If dough is difficult to handle (sticky, slack): reduce dosage by 0.25%; lower dough temperature to 26°C.

Step 5: validate allergen declarations and label

Before launch, have the new ingredient list reviewed by your technical team or an external food labelling consultant. Confirm processing aid status of enzymes with the enzyme supplier (EU Reg. 1332/2008 compliance). Confirm E300 is declared correctly (either as E300 or as ascorbic acid).

Troubleshooting clean-label switches

See [fault-clean-label-switch] in data.json for the complete fault table. Key entries:

| Fault | Most likely cause | Remedy | |-------|-----------------|--------| | Reduced volume vs conventional | Loss of DATEM gluten-strengthening; enzyme system insufficient | Increase dosage; add VWG at 1–2% | | Faster staling | Insufficient maltogenic amylase | Add amylase preparation; add liquid softener | | Slack/sticky dough | Xylanase over-dose; high dough temperature | Reduce dosage; lower dough temperature | | Snap-back on moulder | Loss of L-cysteine relaxation | Extend intermediate proof; add inactivated yeast 0.1–0.2% | | Pale crust | Loss of MDG browning or insufficient dextrins | Add malt extract 0.2–0.5% | | Unexpected soya on label | Previous improver contained soya flour | Confirm new enzyme-only improver is produced on soya-free or soya-separated line |

What enzyme-only systems will not fully replicate

Honesty is important: there are applications where removing emulsifiers does require compromise.

Very soft, enriched rolls (brioche-style, milk bread): The crumb softness achieved by SSL + MDG at 7% dosage (as in IREKS Soft Roll 7) is difficult to fully replicate with enzymes alone. The SSL+MDG starch-lipid complex provides immediate (Day 1) and sustained (Day 5+) softness that maltogenic amylase replicates only partially. These applications typically require a supplementary liquid softener or an emulsifier outside the label claim. [ss-ireks-softroll7]

High-speed industrial lines with very strong flours: DATEM provides a robust, reproducible dough tolerance that enzymes — which are more sensitive to flour variability and process parameters — cannot always match. A VWG buffer (1–2% on flour) helps but is not always sufficient. [src-056]

Extended frozen or retarded doughs: Some emulsifiers improve freeze-thaw stability of the gluten network. Enzyme-only systems behave differently under freezing; dedicated frozen bread enzyme systems are available from suppliers but are beyond the scope of the current Domson catalogue range.

These limitations should be disclosed to the baker during any clean-label reformulation consultation.

Coverage notes

Solid: Zeelandia clean-label improver specs (Gamma GP, Optimax Free, Rye Stabil Free) — first-party, complete, high confidence. Beneo VWG 75 spec — first-party, complete, high confidence. Conventional comparator specs (Puratos, IREKS) — first-party, complete, high confidence. Regulatory framework (EU Reg. 1332/2008, 1333/2008; UK Bread and Flour Regs 1998) — primary legal sources.

Thin (single-source, confidence: low): GOX dosage range (c5); L-cysteine dosage (c4); inactivated yeast dosage (c27); maltogenic amylase shelf-life data (c20); DATEM and SSL pure-ingredient dosage ranges (c1, c2). Each flagged with confidence level.

Missing / needs follow-up: First-party spec sheets for Zeelandia Gamma GP and Optimax Free do not specify which enzyme class is present (xylanase? lipase? amylase?) — described generically as "enzyme". Request enzyme class disclosure from Zeelandia for more precise replacement mapping. No independent head-to-head volume comparison data between Gamma GP and S500 SG was available — a controlled bake trial would be the definitive verification.
