Polysorbate 80 is often contained in products that are described as a worldwide breakthrough.

Polysorbate 80 is also referred to as E433. It is a synthetic emulsifier approved as a food additive in Europe. Also sometimes relatively high proportions of polysorbate 80 can be found in food supplements. Continue reading →

As is generally known, Curcuma longa contains three important curcuminoids:

• Curcumin
• Bis-demethoxy curcumin
• Demethoxy curcumin

The percentage of curcumin is by far the highest.

For some time now, the high-quality plant substance curcumin has also been produced synthetically. In contrast to curcumin, bis-demethoxy-curcumin and demethoxy-curcumin cannot be synthetically produced. Some producers mix these two natural curcuminoids with a much cheaper artificial curcumin for financial reasons. A safe, but also costly and cost-intensive process for documenting the naturalness of curcumin is the so-called “C14 method”. This is also called “isotopic measurement” or “radiocarbon dating”. Synthetic curcumin is made from petroleum and can therefore be identified by the amount of C14 carbon atoms. Continue reading →
