Popular questions
What is sodium copper chlorophyllin?
A water‑soluble green colorant made from plant chlorophyll, where the central magnesium is replaced by copper and the molecule is converted to sodium salts.
Is sodium copper chlorophyllin safe?
Yes—it's authorized as a food color in many regions and considered safe at permitted levels; it contributes a small amount of copper, so those who must limit copper (e.g., Wilson’s disease) should be cautious.
What is sodium copper chlorophyllin used for?
Coloring foods and beverages green, for example confectionery, drinks, sauces, and bakery icings.
What does sodium copper chlorophyllin do?
It imparts a bright, water‑soluble green color that is more light‑ and heat‑stable than natural chlorophyll.
How much copper is in sodium copper chlorophyllin?
Additive specifications typically place copper at about 4–6% by weight of the ingredient; the copper delivered in a food depends on the amount of colorant used.
Is anthocyanin always present in leaves?
No—anthocyanins vary by species and conditions; many green leaves have little to none until they’re young, senescing (autumn), or under stress such as high light, cold, or nutrient limitation.
How much anthocyanin per day?
There’s no recommended daily intake or established ADI; typical diets supply roughly a few tens to a few hundred milligrams per day from fruits and vegetables, and intake at normal food levels is considered safe.
What colors come from anthocyanins?
They give red, pink, purple, and blue hues, shifting with pH—more red in acidic conditions and more blue/purple as pH rises.
How to extract anthocyanin from plants?
Crush colored plant material and soak it in acidified water or food-grade ethanol (e.g., 50–70% ethanol or water with a little lemon juice), then filter; keep the extract cool, protected from light, and away from high pH to limit degradation.
What are anthocyanins good for?
As E163, they’re used to color foods and drinks in red-to-blue shades; while they show antioxidant activity in vitro, human health benefits remain limited and inconclusive.
