In China, there is currently no complete standard system for how plant extracts can be used as food raw materials. Exported extracts are generally subject to quality and safety supervision in accordance with the regulatory requirements of the exporting country. According to the quality and safety supervision requirements of food raw materials in European, American and Asian countries, supervision of safety indicators is relatively strict, especially there are special limit requirements for pesticide residues, solvent residues, polycyclic aromatic hydrocarbons and mycotoxins.
Mérieux Nutritional Science Testing Laboratory has developed a comprehensive monitoring service for safety testing of extracts. The details are as follows:
security indicators:
Pesticide residue index
70-item multi-pesticide testing series for Chinese herbal medicines in the United States Pharmacopoeia
A series of 60+ pesticide residue tests for Chinese herbal medicines in the European Pharmacopoeia
Monitoring list of 33 banned pesticides in the Chinese Pharmacopoeia
Monitoring list of 260+ items for Chinese medicinal materials and extracted pesticide residues
Other security indicators
Identification of authenticity: thin layer identification, infrared identification, mass spectrometry identification, etc.;
Solvent residue: methanol, ethanol, acetone, methylene chloride, chloroform, ethyl acetate, n-hexane, isopropyl alcohol, toluene, etc.
