Inspection and quarantine reminder: the export of plant extracts needs to strengthen the control of raw materials

Recently, a batch of grape seed extracts produced by an enterprise in Ningbo and exported to Canada were returned by customers, with a weight of 600 kg and a value of 13000 US dollars It is reported that the reason for the return of goods is that foreign customers have detected that the residual content of Pythium is 1.22 ppm, which does not meet the contract requirements of 0.1 ppm of the other party Grape seed extract is a kind of commonly used health product raw material at home and abroad Its main component is anthocyanin, which has anti-oxidation, clear free radicals and other anti-aging effects The main raw material of grape seed extract production is grape seed or grape skin Grape seed, as a by-product of wine making and grape juicing process, is often used to control leaf blight due to the use of Pythium profits in grape planting, resulting in Pythium profits left in the residual raw material of grape seed It is reported that in the production process of grape seed extract, although most pesticide residues have been removed by macroporous resin adsorption and other technologies, due to technical limitations, the concentration of fungicide Pythium can be effectively detected eventually, which can not meet the use requirements of customers After receiving the goods for inspection, Canadian customers found that the residual amount of Pythium was 1.2ppm, which was not up to the limit requirement of 0.1ppm in USP standard, which affected the use of customers Therefore, they raised an objection to the quality of the goods and asked the goods to be returned The enterprise actively reached the intention of return The export of plant extracts in Ningbo increased year by year In this regard, the inspection and quarantine department suggested that the extract export enterprises should improve the traceability management, strengthen the control of raw materials, strengthen the sampling inspection of raw materials to ensure that the raw materials meet the requirements; control the quality, strengthen the production process control and finished product inspection, improve the sampling inspection power of pesticide residues such as Pythium; continue to develop new technologies, reasonably use filtering and other effective separation methods in the production process to reduce the cost Pesticide residues in the extract.
