Deep Analysis of Food Additive E551 in Europe and America
Regional labeling norms: The EU uses E-codes for standardized additive identification, while the U.S. requires common names. Both refer to the same food-grade substance.
1、E-Code & Label Truths (1-15)
1.What does "E551" mean on European food labels? Is it the same as silicon dioxide?
Yes, E551 is the EU additive code for silicon dioxide. It’s identical to the "silicon dioxide" listed on U.S. labels, used as an anti-caking and stabilizing agent.
2.Why do U.S. labels say "silicon dioxide" but EU labels use E551?
Regional labeling norms: The EU uses E-codes for standardized additive identification, while the U.S. requires common names. Both refer to the same food-grade substance.
3.Is E551 ever hidden in "natural flavors" or "processing aids" without labeling?
In the EU, it must be labeled if added directly. But as a processing aid (e.g., during filtration), it may be excluded if no residue remains. The U.S. has similar rules for GRAS processing aids.
4.Why did Santa Maria advise celiacs to avoid spices with E551?
Not due to E551 itself (it’s gluten-free), but potential cross-contamination during production (e.g., shared equipment with wheat-based ingredients).
5.Does "no E551" on a label mean the food is healthier?
Not necessarily. E551 prevents caking and spoilage. "No E551" products may use alternatives like rice flour, which add calories or allergens.
6.How can I tell if E551 in my food is nano-sized?
Currently, EU law only requires labeling if nano-particles make up >50% of the additive. This loophole lets manufacturers avoid disclosure for 49% or less.
7.Why do some organic labels include E551? Is that allowed?
The EU permits E551 subtypes (e.g., colloidal silica E551b, diatomaceous earth E551c) in organic foods, as they’re derived from natural silica sources.
8.Is E551 listed on vegan/vegetarian certifications?
Yes, it’s vegan-friendly (no animal origin). Certifications like Vegan Society mark products with E551 as acceptable.
9.Does "non-GMO" guarantee no E551?
No. E551 is inorganic (not derived from organisms), so GMO status doesn’t apply. It’s often added to non-GMO powdered foods.
10.Why do French consumer groups criticize E551 labeling?
They argue EU rules let companies hide nano-E551 (≤49% content). A 2025 investigation found "nano-free" labels on products with 42% nano-E551........
