ASTM WK67893

    New Guide for Sampling of Hempseed Intended for Human Consumption

    (What is a Work Item?)

    Developed by Subcommittee: D37.07 | Committee D37 | Contact Staff Manager


    1. Scope

    1.1 This guide covers recommended steps used in collection of a representative field sample of bulk hempseed intended for human consumption. 1.2 This guide applies to plant breeders, hemp seed producers/farmers, seed cleaners, storage facilities, laboratories, and processors who handle bulk hempseed. 1.3 UnitsThe values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This 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.

    In agriculture, sampling is likely one of the most important objective indicators of lot stability, health, and in many cases, product value. In the nutritional cannabis (hemp) industry sampling is required at all levels of cultivation and processing and important decisions are made based on the various tests conducted as part of a certificate of analysis. Bulk nutritional cannabis (hemp) seed/grain storage requires regular sampling conducted in a consistent, standardized, verifiable manner. Sampling done for the purposes of microbial and physical property analyses, if done correctly, can lead to clear positive outcomes throughout the value chain. Done improperly, sampling can be seen to add bias, inaccuracy, and can lead to microbial contamination of a sample or, even worse, the entire batch. Where test results from sampling often determine if a seed/grain lot/batch is to be purchased or not and at what price, there is a significant economic incentive to ensure that sampling is done correctly, every time, by all participants. Getting it wrong can spell disaster setting in motion a chain reaction of questionable decisions made on bad information affecting individual farms or possibly, an entire industry. Since nutritional cannabis (hemp) is generally sold raw to the consumer, there is considerable concern for microbial contamination. There is also a considerable need to maximize/maintain the natural aesthetics of the numerous hemp food products so that the look, taste, feel, and smell of the product can be replicated and standardized. Proper sampling technique is the key. However, without a standardized sampling process there is no way to guarantee that the data generated from testing lots/batches of bulk seed/grain will be reliable/usable. This standard will address this issue.

    The title and scope are in draft form and are under development within this ASTM Committee.
