摘    要:目的 了解深圳市场转基因大豆及其制品的市场占有率和标识情况,为政府监管转基因大豆提供科学依据.方法 按照监测计划,定期在深圳市场随机抽取大豆及其制品,采用实时荧光PCR方法对其进行定性和定量检测,评估深圳市场转基因大豆的市场占有率和标识情况,并与2006年的监测结果进行比较和分析.结果 2011年共监测样品106份,检出2份转基因阳性样品,市场占有率为1.89%;两份阳性样品中转基因大豆的含量分别为0.93%和0.51%,定量检出限为0.1%.所有检出转基因阳性样品均没有转基因标识;与2006年结果比较,转基因大豆及其制品的市场占有率以及标识情况差异均无统计学意义.结论 目前深圳市场转基因大豆及其制品(食用油脂除外)的市场占有率还很低,并且5年来未发现明显上升;转基因产品标识的管理还有待加强,政府应该加大这方面的执法力度.

关 键 词:转基因大豆  调查  市场占有率  标识

Abstract:Objective To obtain the data of market share and labeling status of genetically modified(GM) soybeans and their products in Shenzhen and provide scientific basis for government regulations.Methods In accordance with the monitoring plan,soybeans and their products were randomly collected from markets in Shenzhen on a periodic basis.Qualitative and quantitative detection of GM ingredients were carried out by real time polymerase chain reaction(PCR).The market share and labeling status of GM soybeans and their products were assessed,and the results were compared to those of 2006.Results 106 samples were monitored in 2011,and two samples were found to contain GM ingredients with the content of 0.93% and 0.51% respectively.The market share of GM soybeans and their products was 1.89%.There was no GM labeling on the packages of GM positive samples.Compared to the results of 2006,no significant differences were found in the market share and labeling status of GM soybean products.Conclusion Current market share of GM soybeans and their products in Shenzhen(except edible oil) was still very low,and there was no significant increase in the past five years.The management of GMO labeling still needs to be strengthened,and government should intensify law enforcement on this issue.
Keywords:Genetically modified soybeans  investigation  market share  labeling
