Paprika Oleoresin: Colour Value, Capsaicin and Compliance

Bought on Colour Units

Paprika oleoresin is sold on colour value, expressed in colour units. The common commercial grades are 40,000, 80,000 and 100,000 CU.

That basis reflects how it is used: a formulator works out inclusion from the colour required in the finished product, so the useful number is colour delivered per kilo, not a percentage of anything.

The Line Most Specifications Miss

Residual capsaicin.

Paprika is Capsicum annuum — the same species as chilli. Colour varieties such as Byadgi are selected for low pungency, but extraction concentrates whatever capsaicin the pods carried. Low is not zero.

Two consequences:

1. Sensory — unexpected heat shifts the flavour of a delicately seasoned product, and the cause is rarely suspected because the ingredient is filed mentally as "colour";
2. Regulatory — in the EU, the E160c paprika extract specification limits capsaicin content, on the principle that a colour additive should not season the food.

So if you use this material as a declared colour, residual capsaicin is a compliance parameter and belongs on your incoming specification. Require it as a tested figure per batch.

Colour Additive or Spice Extract?

A distinction worth settling early, because it changes your labelling.

Which route applies depends on your finished product and how the material functions in it. That determination belongs with your regulatory reviewer — the supplier's job is to provide a certificate detailed enough to support it, capsaicin figure included.

Sudan Dyes

Paprika sat at the centre of the illegal-dye contamination episodes that prompted large-scale product withdrawals across Europe and sustained official import controls on paprika and chilli products from several origins.

Consequently:

• Sudan I–IV screening is a baseline expectation, not a premium service;
• Check the current control status for your destination before shipping — listings and control frequencies are revised;
• A supplier not screening routinely is not set up for this trade.

Colour Stability

Carotenoids are sensitive to light, oxygen and heat. Practical implications:

• Store cool, dark, tightly closed, protected from air — colour value degrades in poor storage;
• Expect losses through high-temperature processing; dose against the finished product, not the ambient sample;
• Where an antioxidant is added to protect the carotenoid fraction it should be declared — relevant for clean-label positioning and allergen review.

Carrier Declarations

Grades standardised to a fixed colour value usually involve a carrier. Require it named with its inclusion level, alongside any antioxidant. Without those, two quotations at the same CU are not comparable, and a supplier switch at the same nominal grade can change dispersion behaviour in your system.

What to Require

1. Colour value, with the basis stated;
2. Residual capsaicin by HPLC, per batch;
3. Sudan I–IV screened, reported not detected;
4. Solvent named, residual level by GC;
5. Carrier and antioxidant declared with inclusion levels;
6. Aflatoxins and ochratoxin A; heavy metals by ICP-MS;
7. Pesticide residues to EU MRL where the destination requires;
8. Full microbiological panel.
