This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the
Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
Designation:D8440 −22
Standard Specification for
Food Safety and Quality of Hempseed Products Intended for
Human Consumption
This standard is issued under the fixed designation D8440; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
The processing of hempseed results in several food products such as toasted hempseed, dehulled
hempseed, hemp seed oil, and hempseed protein products. These products in which hempseed is the
main or sole ingredient may be consumed with no microbial pathogen reduction step to manage food
safety risk. Specifications relating to food safety and shelf-life attributes are defined in this
specification to protect buyers and consumers from food safety risk, and where possible, address shelf
life as it relates to potential spoilage. Meeting these specifications will assist product consistency and
business-to-business (B2B) transactions.
