Detection of plasticizer monomer in red ganoderma lucidum's fruiting body and analysis of its migration
Objective To know the pollution of plasticizer in ganoderma lucidum in the main producing area of forging-wood red ganoderma lucidum,Wuyishan area,and analyze the immigration from the raw material to ganoderma lucidum in the production process.Methods According to the national food pollution monitoring standard operating procedures,sixteen plasticizermonomers,including dimethoxyethyl phthalate(DEHP) and dibutyl phthalate (DBP),were inspected and analyzed with fresh and dried ganoderma lucidum fruiting body picked up in three ganoderma lucidum planting bases in Wuyishan area.Do the plasticizer monomer monitoring of the main plasticizer enrichment of water,forging-wood and auxiliary material in the growth medium of three bases.The analysis of the inspection of the immigration and source of ganoderma lucidum'splasticizer is done.Results In ganoderma lucidum,the DEHP and DBP which are regularized by our country are found.DEHP is 1.5 mg/kg approximately and one base exceeds the standard and the concentration of DBP is within 0.35 mg/kg-0.58 mg/kg,which is excessive project.Seen from production environment and production matrix,DEHP is shown as water pollution to some extent.Conclusion There may be plasticizer migration pollution in the planting process.The 2 plastic tubes used for introducing water is the possible source of 2 plasticizer monomers,DCHP and DEHP.
