Nix v. Hedden aids to the memory and understanding of the court. Gray acknowledged that botanically, tomatoes are classified as a "fruit of the vine"; nevertheless, they are seen as vegetables because they were usually eaten as a main course instead of being eaten as a dessert. In making his decision, Justice Gray mentioned another case where it had been claimed that beans were seeds — Justice Bradley, in "Robertson v. Salomon," 130 U.S. 412, 414, similarly found that though a bean is botanically a seed, in common parlance a bean is seen as a vegetable. While on the subject, Gray clarified the
International Fruit and Vegetable Juice Association as an NGO at government and international organisations. It acts as a regulatory information centre and supports harmonisation of international regulatory standards and practices across the juice sector. The Methods of Analysis Commission, chaired by Mikko Hofsommer of GfL in Berlin, has as its primary mission to create and standardise methods of analysis, specifically for processed fruit and vegetable products. Most of the published IFU methods are listed as official methods in codex. The Microbiology working group, chaired by Andreas Politzer and Rudolph Wild is a subgroup of the methods of analysis commission, focuses on similar issues within their field.
