Popular questions
What is blue 1 made of?
A synthetic triarylmethane dye used as a food color; it's the disodium salt of a sulfonated aromatic compound and is water‑soluble. An insoluble 'lake' form is made by depositing the dye onto aluminum hydroxide for use in fats and coatings.
What does blue 1 do to your body?
At typical dietary levels it has no known physiological effect; most ingested Blue 1 is poorly absorbed and is excreted. Rarely, sensitive individuals may have allergic-type reactions or temporary blue-green stool/urine.
Is blue 1 dye bad for you?
No—major regulators (FDA, EFSA, JECFA) consider it safe at permitted levels, with an EFSA ADI of 6 mg/kg body weight per day. Adverse reactions are uncommon and usually limited to rare hypersensitivity.
How is blue 1 made?
It’s synthesized from petroleum‑derived aromatic compounds by constructing a triarylmethane core, then sulfonating and oxidizing it to a water‑soluble disodium salt. The 'lake' form is produced by precipitating the dye onto aluminum hydroxide.
Does blue 1 cause cancer?
Current evidence does not show that Blue 1 causes cancer at permitted food-use levels. Long-term animal studies and evaluations by EFSA/JECFA have not identified carcinogenic or genotoxic concerns.
Is copper in chlorophyll safe?
Yes—copper complexes of chlorophylls (E141(i)) are approved food colorants and considered safe at permitted levels; keep total copper intake within dietary limits, and people with Wilson’s disease should avoid excess copper.
Does chlorophyll have copper?
Natural chlorophyll contains magnesium, not copper; in E141(i), the magnesium is replaced by copper to stabilize the green color.
What is sodium copper chlorophyll?
Sodium copper chlorophyllin is the water‑soluble form of copper chlorophylls (classified as E141(ii)), made by converting chlorophyll to chlorophyllin and substituting copper, and used as a green coloring.
(chlorophyll copper complex (who-dd)?
WHO/FAO’s JECFA has evaluated copper complexes of chlorophylls/chlorophyllins and set purity specifications, finding no safety concern at approved use levels.
Chlorophyll copper complex who?
WHO/JECFA considers copper chlorophyll complexes acceptable as food colors when used within good manufacturing practice and established specifications.
