Antioxidant activity
ABTS and DPPH assays showed radical-scavenging activity, increasing with concentration within the tested range.
Water-Soluble Food Formulation Ingredient
AC-EnzyMIQ
Chemical name: Enzymatically Modified Isoquercitrin
CAS No. 977187-64-6
WATER-SOLUBLE ANTIOXIDANT FOR COLOR STABILITY
Prevents oil oxidationInhibits discolorationInhibits flavor deterioration
AC-EnzyMIQ is a natural antioxidant from enzymatically treated rutin of Sophora japonica. The treatment boosts water solubility, making it ideal for preventing oxidation in beverages and jellies. Its strong UV absorption prevents color fading and flavor deterioration.

Function and performance
Radical scavenging and color protection
Laboratory assays and model beverage trials address different aspects of AC-EnzyMIQ performance.
Color stability under light
Model beverage tests compared color appearance with and without EnzyMIQ during direct sunlight exposure.
Study conditions
The color trials used 0, 50 and 100 ppm EnzyMIQ at Brix 10 and pH 4.5. Colorants included monascin, capsanthin and gardenia green. Exposure times differed between colorants; the observations apply to these test systems.
Application
AC-EnzyMIQ formulation guide
- Prepare the aqueous phaseDissolve EnzyMIQ and mix uniformly with the beverage base.
- Set the trial conditionsUse the intended colorant, acidity and soluble-solids content.
- Compare packaged samplesMonitor color and flavor with a control under the intended light and storage conditions.

FAQ
AC-EnzyMIQ questions
Are 50 and 100 ppm universal use levels?
They are concentrations used in the model color trials. The appropriate level depends on the finished product and permitted use.
Does a radical-scavenging assay predict a health effect?
These assays measure chemical antioxidant activity in the test system. They do not establish a health outcome in people.
