Abstract: This article aims to lay a good basis for decision-making for the development and revision of future standards. The bibliometric analysis results can be taken as the indications for the development, revision and distribution of standards as well as future trend of standardization. This article based on bibliometric analysis, the national food standards of foreign countries, including Britain, Germany, France, Russia, the United States, and China are thoroughly compared and analyzed in terms of the quantity, standard age, publication date, technical field and adoption rate of international standards. The results showed that, in China, the amount of active food standards was 2242; the percentage of standard age less than 5 years ranked only second to the United States; the publication peak of food standards was 2009. The technical fields of food standards in China were mainly distributed in food products in general, methods of tests and analysis for food products, and food additives, etc. The standard numbers of some food technical fields, for example, milk and milk products, materials and articles in contact with foodstuffs, plants and equipment for the food industry, should be increased. The domestic adoption percentage of international standards was relatively low, merely 18.02%. The consistency extent of standards was lower than that of other countries. The standard timeliness was not high, and the number of adoption of international standards issued within 5 years was relatively few, therefore, it is recommended to shorten the time difference of adoption of international standards.
