Multi-method pesticides in Moringa powder (P1912-RT)

Over the last year, green smoothies became a new food trend in Europe. As a consequence, new products like wheat grass, barley grass and moringa leaf powder are consumed. These products are advertised as "superfoods" and offered as "healthy food" or nutritional supplements. 

 

Moringa olifera is a plant that is nativ in India, Africa and Asia. The leaves, bark, flowers, fruit, seeds and root are used as medicine and food supplement by the native population. 

Due to the high demand for such rare superfoods the residues situation can be questionable. CVUA Stuttgart conducted a number of analysis in order to evaluate the residue situation of pesticides in Moringa in 2016 and 2015 (http://www.cvuas.de). The maximum residue level was exceeded in 9 our of 11 samples in 2016 and unauthorised pesticides were found in six out of seven organic samples.

 

The test material of P1912-RT consists of spiked Moringa leaf powder (50 g). The moringa powder is spiked with pesticides, which are typical for products like moringa powder, wheat grass powder, and barley grass powder. The spiked pesticides are within the scope of common pesticide multi-residue methods (GC and LC). 

 

The aim of the ring test is

  • the correct identification of the spiked pesticides.
  • the correct quantification with respect to the
    trueness criterion (70-120 % recovery of the spiked level).
  • the correct quantification with respect to the
    comparability criterion (z-score ≤ |2|).
