GB/T 22478-2008Grapeseed oil (English PDF)

1 Scope

GB/T 22478-2008 is the Chinese national standard on grapeseed oil, in the field of food technology. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 4 November 2008 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 20 January 2009. Classification: ICS 67.200.10, CCS X14. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This Standard specifies the relevant terms and definitions, quality and hygiene requirements, inspection methods, inspection rules, labeling and marking, packaging, storage, transportation and other requirements of grapeseed oil. This Standard applies to commercial grapeseed oil processed from grapeseed for human consumption.
