Minerva Scientific introduces matrine and oxymatrine testing of honey
Derby, UK, 19.05.2022 (PresseBox) - There have been four EU RASSF alerts concerning detectable levels of the pesticides oxymatrine and matrine in Chinese honey within the past 12 months, with most of these alerts relating specifically to Chinese Acacia honey. There was also a product recall of retail Acacia honey containing ‘high’ levels of oxymatrine in France in August last year.
Matrine and oxymatrine are both commercially available as pesticide formulations with wide-ranging properties. The compounds are naturally occurring plant alkaloids also known to be present in significant concentrations in the flowers and other plant material of Sophora flavescens, a shrub-like tree growing extensively in some regions of China. The trees are reported to be found in regions where Acacia trees are also abundant and therefore where Acacia honey is produced. The two tree species are known to flower over the same short period of time hence introducing the possibility that natural oxymatrine and matrine are transferred to Acacia honey by the honeybees foraging on Sophora nectar containing traces of these compounds. Alternatively, traces of these compounds may have been introduced into honey through usage of commercial formulations of matrine and oxymatrine in the region.
Despite the possibility that detected residues of matrine and oxymatrine may be due to natural occurrence these compounds are classified as pesticides and have no maximum residue level (MRL) set for honey in either EU or UK legislation and are therefore not permitted. The legal MRL for each of these compounds in all food commodities including honey is 0.01 mg/kg (parts per million), or 10 parts per billion (ppb) by default.
In anticipation of an industry need for rapid testing of these residues in honey Minerva has established a LC-MS/MS procedure for their trace-level detection.
