What Is ORAC? How Buyers Should Evaluate Açaí Antioxidant Claims

If you sell or source açaí, you will see one number again and again: ORAC. It is often quoted without context, so buyers don't know whether a high value is meaningful. Here is the short, honest version.

What ORAC measures

ORAC stands for Oxygen Radical Absorbance Capacity. It is a lab measure of how well a food neutralizes free radicals — reactive molecules linked to oxidative stress in the body. It is expressed in µmol TE (Trolox Equivalents) per 100 g. A higher number means greater antioxidant capacity per gram.

Why a single headline value can be misleading

ORAC results can change with harvest, moisture, sample preparation, laboratory method and reporting basis. Freeze-drying removes water and can concentrate compounds per gram, but that does not justify applying one historical result to every SKU or lot. Buyers should request the method, sample identity and batch-specific report whenever an ORAC value is commercially relevant.

What this means for the final product

• Intense natural color that survives in the cup, on the plate and in the display.
• Anthocyanins and polyphenols delivered with little dilution.
• A technical story supported by documentation for the ingredient actually purchased.

A note on responsible claims

ORAC describes antioxidant capacity measured under laboratory conditions, not a guaranteed health outcome in the body. Results should be attributed to the tested sample, and nutrition or health claims must follow the rules of the destination market. Used responsibly, ORAC is supporting analytical context — not a universal product promise or medical claim.
