美国明尼苏达大学食品保护与防御中心经济利益驱动型掺假数据库分析及学术地图可视化呈现

目的 统计分析明尼苏达大学食品保护与防御中心(National Center for Food Protection and Defense, NCFPD)经济利益驱动型掺假(economically motivated adulteration, EMA)数据库数据, 呈现学术地图可视化。 方法 对1980~2018年NCFPD-EMA数据库数据作统计分析, 并运用浙江大学学术地图发布平台 (http: //amap.zju.edu.cn)软件技术进行可视化呈现。结果 EMA事件在东南亚、西欧、北美的发生率较高, 掺假主体以农产品(65.7%)为主, 掺假组分依次为饮料(16.0%)、肉制品(14.3%)、食用油和油脂及其制品(12.3%)、水产制品(10.3%)和乳制品(9.9%); 掺假手段以稀释或替代(44.5%)为主, 且事件多数发生在加工环节(68.7%); 构建了酒及饮料类, 蔬菜及水果类、粮食加工品、乳制品、肉制品、食用油和油脂及其制品等6幅学术地图。结论 借鉴NCFPD-EMA信息和大数据技术建立“中国EMA数据库”很有必要, 采用学术地图EMA可视化呈现具有直接性、集中性和交互性的特点。

Analysis and visualization of academic maps on economically motivated adulteration database of the center for food protection and defense, university of Minnesota, USA

Objective To count and analyze the economically motivated adulteration (EMA) database data of the National Center for Food Protection and Defense (NCFPD) in the University of Minnesota, and present the academic map visualization. Methods The data of the NCFPD-EMA database from 1980 to 2018 were analyzed, and the visualization of NCFPD-EMA software technology was carried out by using the software technology of the academic map of Zhejiang University (http://amap.zju.edu.cn). Results The incidence of EMA events in Southeast Asia, Western Europe and North America is higher. The main adulterators are agricultural products (65.7%), beverages (16.0%), meat products (14.3%), edible oils, lipids and their products (12.3%), aquatic products (10.3%) and dairy products (9.9%), successively. The main adulteration mean is dilution or substitution (44.5%), and most of the incidents occurred in the processing sector (68.7%), and 6 maps on wines and beverages, vegetables and fruits, food processing products, milk and dairy products, meat products, edible oils and lipid products were edited. Conclusions It is essential to construct the EMA database of China by using the technology of NCFPD-EMA as reference. Visualization of EMA by using academic maps has characters of direct, concentration and interaction.
