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 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.
On the recipe you have on screen, the panel breaks each commercial stabilizer —Cremodan SE-30, SL-29, SIM VEG, Vandoburin 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. |
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. |
None of this is opinion. The knowledge base rests on the field’s references, and the analysis uncovered nuances that live inside the tool:
Pick a component and its dosage and watch how long the scoop holds before it melts. It’s the real strength of each gum against heat shock (Regand & Goff), not an impression: carrageenan and xanthan hold up better than locust bean gum, and overdosing leaves it gummy.
Deterministic model over the knowledge base (strength against melting, saturation and overdose per component). Indicative.
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.

The dosage ranges are indicative and support the professional’s decision; the supplier’s technical data sheet prevails. FormulaMaps does not replace the workshop’s own trials.
