How to Detect Petrochemical Adulteration in Curcumin

Curcumin is one of the major curcuminoids found in turmeric and has many uses from food and supplements to cosmetics. In 2015, the size of the curcumin market exceeded $39 million with the majority of use seen in the pharmaceutical and food industries.1 As consumers have become increasingly health and environmentally conscious, the demand for naturally sourced ingredients has grown across many industries, as has been seen for curcumin.

Curcumin’s distinctive yellow color and flavor have made it a popular spice. It has also been used in traditional medicines. The use of curcumin in cosmetics has originated from the increasing desire for natural products and its associated health benefits.

As a supplement it is seeing a boost in usage based on its health benefits.2 Due to turmeric having low bioavailability, curcumin itself is preferred for use in the supplement form. Curcumin is known as an anti-oxidant, anti-inflammatory and even a defense against Alzheimer’s disease and cancer. There has, however, also been some skepticism on the its effectiveness due to bioavailability issues.3,4

Curcumin Adulteration – Natural Product Testing

curcumin carbon-14 analysis

The natural source of curcumin is the turmeric plant. However, it is cheaper to produce synthetically from petrochemicals. With its myriad of uses and applications and increasing popularity, it is no surprise that curcumin is prone to economic adulteration with the cheaper to produce petrochemical sourced form. This also means that the detection of this adulteration has become increasingly important for manufacturers and suppliers of curcumin, both for quality control and as an assurance to consumers proving the authenticity of natural curcumin.

The Carbon-14 content of a material accurately indicates the proportion of naturally sourced curcumin. The analytical standard ISO 16620-2 outlines the measurement of the percentage of biobased carbon content of total carbon in a product using the Carbon-14 method. More details on the basis of Carbon-14 testing can be found in this curcumin page.
