Calcium Disodium EDTA, FCC is used as a flavor and color preservative.

EDTA- Calcium food grade offers excellent processing flexibility. It’s a white crystalline powder which dissolves readily in water. EDTA- Calcium food grade is essentially odorless, colorless, and tasteless at recommended use levels.

Uses and Benefits

When you use food-grade EDTA chelating agent in your beverage product, you’re helping to ensure consumers enjoy the same bright, distinct tastes and colors you worked to create.

And food-grade EDTA chelating agent can help preserve the potency of important vitamin additives such as Vitamins C, A, D, and E.

Why Metals are a Problem

Metal ions, such as iron, copper, and zinc (from sources including packaging, process water, or raw materials) are often present in products. These metal ions are highly reactive in beverages; they initiate and catalyze oxidation of flavors and colors.

This is a particular problem with certified colors and when any ascorbic acid (Vitamin C) or benzoate preservatives are present. Even at levels below 0.1 ppm, metal ions can cause discoloration, flavor change or degradation of the vitamin content.

How Food-grade EDTA can Help

Food-grade EDTA (ethylenediaminetetraacetate) preferentially binds with free iron, copper and other trace metal ions (as well as metals in a number of naturally occurring enzymes) to form stable ring structures.

The chelated metals cannot react and cause product degradation, so shelf life is extended, and beverages are of the highest quality.

Unmatched pH Stability

EDTA forms extremely stable complexes with metals across a very wide pH range.

Although citric acid, phosphates, and lactates are sometimes promoted as metal ion control agents in food applications, they can’t match the performance of EDTA, particularly at acidic pH.

Outstanding Performance in Beverages Fortified with Vitamin C

In Vitamin C-fortified beverages, uncontrolled metal ions can interact with the Vitamin C to destabilize flavors, deteriorate colors, reduce shelf life, and degrade benzoate.

Food-grade EDTA prevents these effects while preserving the nutrient value of the Vitamin C.
