Buying Heat: Capsaicinoids and SHU

Heat is measured by HPLC as total capsaicinoids, mainly capsaicin and dihydrocapsaicin. Scoville heat units (SHU) are then calculated from that figure. The conversion factor is not universal, so a quotation that gives SHU without the capsaicinoid percentage and the conversion basis cannot be compared with another. Ask for both. Also ask for the carrier oil and its inclusion level on standardised grades: two oleoresins at the same nominal SHU can carry very different amounts of diluent. Our chilli oleoresin buyer’s guide covers the heat bands in detail.

High-pungency capsicum oleoresin is a strongly irritant material, and handling guidance should ship with the specification. See the capsicum oleoresin page for the handling notes we send.

Buying Colour: Colour Units

Paprika oleoresin is quoted in colour units because the buyer’s calculation is colour delivered per kilo of finished product. A 100,000 CU grade at half the dose does the work of a 50,000 CU grade. Compare quotations on the same colour-value basis and the same carrier. Capsaicin is declared because a paprika colour that brings noticeable heat is the wrong material for most uses. The paprika colour value guide explains the measurement.

The Regulatory Split

In the US, all three oleoresins are GRAS for flavour under 21 CFR 182.20: capsicum and chilli as “capsicum”, paprika as “paprika”. Paprika oleoresin used to colour food is also a colour additive exempt from certification under 21 CFR 73.345, and the label follows its function (see our guide to the US status of spice oleoresins).

In the EU, paprika extract used as a colour is the additive E 160c (paprika extract, capsanthin, capsorubin) and must meet the specification in Regulation (EU) 231/2012. An oleoresin bought for heat is not sold as E 160c.
