Determination and risk assessment of plasticizer in pre-packaged Chinese white wine of Guangzhou City

ObjectiveTo investigate the risk control of plasticizers in Chinese white wine since the risk assessment results of plasticizers in Chinese white wine products in 2014 released by The National Health and Family Planning Commission.MethodsOne hundred Chinese white wine samples were collected from physical stores， online supermarkets and liquor stores in Guangzhou. According to Method for the Determination of Phthalates Esters in Food （GB 5009.271—2016）， plasticizers in the collected Chinese white wine samples were detected by gas chromatography-mass spectrometry， with the risk reference of Bis （2-ethylhexyl） phthalate （DEHP） and Dibutyl phthalate （DBP） were 5 mg/kg and 1 mg/kg respectively. Chi-square test or Fisher exact test was used to analyze the exceeding and detection rate with P<0.05 was cosidered statistically significant. The point assessment method was used to assess the risk of Chinese white wine plasticizer intake of adult residents in Guangdong Province.ResultsThe excess reference value rates of DBP and DEHP of the 100 Chinese white wine samples were 7% and 1% respectively. Among them， the detection values of DBP and DEHP of one sample exceeded the reference value at the same time. The maximum detection values of the two items （DBP： 47.1 mg/kg， DEHP： 5.55 mg/kg） came from two samples， both of which were produced in 1996， and the detection values of the remaining five samples with excess reference value were below 4 mg/kg and were produced before 2014.The detection rate of plasticizers and the rate of exceeding the reference value of Chinese white wine produced in and before the nominal year of 2014 are higher than those produced after 2014 （P<0.05）. The risk assessment results suggest that when residents in Guangdong Province drink prepackaged Chinese white wine with average consumption， for the low average content of DBP and DEHP in Chinese white wine， the health risks to them are within the tolerance range of human beings， but it may bring some more risks if they drink too much.ConclusionThe DBP and DEHP pollution of prepackaged Chinese white wine sold in Guangzhou is not prominent， but we should pay more attention to the Chinese white wine produced before 2014， and drinkers should control alcohol consumption.
