Which E-numbers does an ice cream stabilizer like commercial stabilizer contain?

Commercial stabilizers combine gums (locust bean gum E410, guar E412, carrageenan E407, CMC E466, alginate E401) with an emulsifier (mono- and diglycerides E471, or sucrose esters E473). FormulaMaps breaks your specific stabilizer down into those E-numbers and explains what each one does.

How much stabilizer do you add to ice cream?

It depends on the type and, above all, on the recipe’s free water: cream 0.10–0.25%, milk 0.15–0.30%, sorbet and vegan 0.30–0.50%, sugar-free 0.40–0.60%. FormulaMaps compares your percentage with the recommended range and tells you whether you are low, right or over.

Is locust bean gum the best stabilizer against recrystallization?

Not always. According to Regand & Goff (2003), carrageenan matches or beats locust bean gum at slowing recrystallization, even though locust bean gum is more famous for its visible cryogel. FormulaMaps ranks the components by their real measured effect.

The first software that tells you what’s inside your stabilizer —and whether you’re overdoing it.

You buy a stabilizer under a brand name and dose it out of habit. FormulaMaps opens the black box: it breaks your stabilizer down into its real E-numbers, explains what each component does for texture, melting and thawing, and compares your dosage with the one recommended for that ice cream type using your recipe’s real free water. From a third-generation ice cream family.

The ice cream maker doses blind

The stabilizer is the most opaque ingredient in the workshop. The label says “stabilizer-emulsifier” and little else, and the dosage is inherited “because it’s always been done this way”. When the ice cream crystallizes in the freezer, melts badly or turns gummy, you don’t know whether it’s the type of gum, the dosage or the emulsifier.

Opaque brand: you don’t know whether your stabilizer contains locust bean gum, guar, carrageenan or CMC —and each one behaves differently.
Dosage by habit: the same 5 g/kg for a cream and for a sorbet, when the free water is nothing alike.
Defects you can’t read: sandy, gummy, weepy melt, heat shock in the display case.

🧬 Stabilizer composition: the black box, opened

On the recipe you have on screen, the panel breaks each commercial stabilizer —all-in-one cream blends, sorbet ones, vegan ones or stabilizers without emulsifier or generics— down into its components and explains, one by one, what they contribute.

Component	E-number	What it does
Locust bean gum (carob)	E410	Cryogel: slows recrystallization; hydrates hot (~80 °C).
Guar gum	E412	Body and viscosity when cold; synergy with locust bean gum.
Carrageenan	E407	Prevents syneresis (whey) and holds the milk proteins; matches or beats locust bean gum at slowing recrystallization.
CMC (carboxymethyl cellulose)	E466	Fast body when cold, inexpensive.
Alginate / xanthan / pectin	E401 · E415 · E440	Body, pseudoplasticity and structure for sorbets and vegan bases.
Mono- and diglycerides (emulsifier)	E471	Destabilizes the fat on purpose (partial coalescence) → drier, creamier ice cream with a better melt.

The fact almost nobody knows: the emulsifier doesn’t “bind” the fat, it destabilizes it in a controlled way so the droplets partially coalesce during churning. That’s what gives the “dry” texture and good shape retention.

The dosage scales with the free water, not with the mix

This is the heart of the analysis. The gum works on the free water —the water not bound by sugars—, so a sorbet or a sugar-free ice cream needs far more stabilizer than a cream. FormulaMaps takes the real free water the engine calculates and compares your percentage with the range for the type:

Dosage bar: the recommended range for the ice cream type (band) versus your recipe’s real percentage, with a low · right · over verdict.

Ice cream type	Recommended stabilizer	Why
Cream	0.10–0.25%	Lots of fat and solids → little gum; with egg yolk, even less.
Milk / milk-based	0.15–0.30%	Less fat → a little more gum to give body.
Sorbet	0.30–0.50%	No fat or emulsifier; lots of free water → CMC/pectin.
Vegan	0.30–0.50%	No casein/egg yolk → more gum + plant emulsifier (E473/lecithin).
High alcohol	0.30–0.50% or more	Alcohol sinks the freezing point → lots of free water.
Sugar-free	0.40–0.60%	Polyols don’t bind water like sugar → maximum gum.

The science, cited

None of this is opinion. The knowledge base rests on the field’s references, and the analysis uncovered nuances that live inside the tool:

Recrystallization (Regand & Goff, 2003): carrageenan ≈ xanthan > locust bean gum > alginate > guar > CMC. Locust bean gum doesn’t “always win”.
Partial coalescence (Goff & Hartel, “Ice Cream”, 7th ed.): the emulsifier destabilizes the fat on purpose.
Protein–polysaccharide incompatibility (Thaiudom & Goff, 2003): why carrageenan holds the milk proteins.
Workshop practice (Corvitto, “Los secretos del helado”): real dosages and defects.

No AI cost: it’s deterministic calculation over a curated knowledge base. When in doubt, the supplier’s technical data sheet rules.

Commercial brands, opened up

This is not theory about loose gums: it is the tub on your shelf. The system estimates which E-numbers each one contains and in what proportion, and translates its dose to your formula.

Here is what the rest of the market does today
The best-known free reference in the field, when it gets to commercial brands, literally says: «if you use a commercial blend, check the instructions on the package».

That is the state of the art. Balancing programs treat the stabilizer as one line with a percentage. None of them tells you what is inside the tub you buy.

🔄 Switch brands without breaking the formula

If you move from one stabilizer to another, the dose is not the same: each brand has its own composition and strength. The system gives you the equivalent dose for that specific recipe.

🫠 Watch it melt before you churn

The simulator animates your formula with each stabilizer: which one stands up, which drips first, which weeps serum. Two-phase physics calibrated against scientific literature.

📚 With the sources on the table

Behind it there is a scientific dossier with cited bibliography (Goff & Hartel, Journal of Dairy Science, EU Regulation 1169/2011) and a declared confidence level for every figure. What is estimated is stated as estimated.

Honesty: the internal proportions of a brand are a trade secret. What we do is a bounded reconstruction based on the label’s ingredient order (mandatory under EU Regulation 1169/2011) and on effective doses published in the literature. It is always declared as an estimate, never as label data.

Unique in the industry

No ice cream software tells you which E-numbers your stabilizer contains and whether your dosage is right for that ice cream type with your free water. The programs balance sugars and fat; none opens the stabilizer. FormulaMaps does.

Better than a course. In one click you get what’s taught in multi-day trainings: which gums to use, at what temperature they hydrate, their synergies, their defects from too much and too little, and the exact dosage for your recipe. It’s workshop knowledge turned into a tool.
