Technote on Hemp food THC regulations

There are new rules set by the European Commission (EC) on the maximum amount of THC permitted on hemp food and oils that contain CBD1. Two of these rules are set by the standing committee of plants, animals, food and feed of the European Union. The first rule states that the maximum acceptable amount of THC in hempseed derived oil should be 7.5 mg/kg or 0.75%. The second rule states that the maximum amount of THC in dry food containing hemp such as hemp seeds themselves or the flour or protein powder that contains them, should not be more than 3mg/kg or 0.3%. Few other countries which are not part of the European Union such as Canada and Switzerland also set standards for hemp food. Canada’s limit on THC content of hempseed derived oil and dry food is 10 mg/kg or 1%. Switzerland’s limit for hempseed derived oil is twice of Canada at 20 mg/kg (2%) and for dry food is at 10 mg/kg or 1%. Figure 1 shows hempseed  derived oil and also hemp based  dry food (hemp Protein powder)

One has to consider, what these limits mean for international hemp international? Based on comments of cannabis lawyers and managing directors of the European Industrial Hemp Association (EIHA), the new rules will help the hemp market to flourish and will avoid the recall of hemp products. Harmonized guideline values applied throughout the hemp market will set the trends and are quite important.

However, not all issues have been resolved and the EIHA is still waiting for further development of the rules. The reason is that each lab has to deal with the uncertainties of measuring the amount THC in hemp food or oil. There is no standard yet for this wiggle or delta and basically producers can still defend the acceptability of their products based on this delta. The EC needs to come up with measurement standards for the uncertainty and only then will the standard have a solid foothold on the hemp market. The suppliers will be given time to adjust to the market by selling their existing stock during a transition period and the rules will be mandatory for all EU members after a period of 20 days from the publication of the regulation in the official journal of the EU. 

One can see irony in the slow pace of EC’s hemp policy because EC also has a policy that states that cultivation of hemp helps the European Green New Deal Objectives (EGNDO)2The EGNDO has the following objectives:

  • Carbon storage: One hectare of hemp sequesters 9 to 15 tonnes of CO2 similar to a young forest but it only takes 5 months to grow

  • Breaking the cycle of diseases: Hemp is able to break the cycle of diseases when it is used in crop rotation. In addition, the fast growth of hemp minimizes the growth of weeds.

  • Preventing soil erosion: Due to having dense leaves, hemp is able to protect the soil from erosion. Hemp can protect the soil after a period of three weeks past germination.

  • Biodiversity: Hemp produces pollen between the months of July to September which coincides with a lack of pollen from other plant species. This will provide shelter for birds and hemp seed is a source of nutrition for animals.

  • No use of Pesticides: Because hemp does not have any natural predators, there is no need to use pesticides.

Another irony pertains to France which is the biggest producer of hemp in the EU (70%) is the country where most of the legal action against hemp has taken place. France is also the country where the most intense battles about regulations in the industry have taken place. This includes the recent court battle to allow selling of hemp flower and not just extracts in the country. As a result of this, it is France that is leading the way in establishing EC’s specific policies on hemp. 

Allied Scientific Pro offers two products that are useful for hemp suppliers to check the THC content of their products to make sure it is within the new regulations imposed on the control of THC in hemp.

The first of these products is the Gemmacert analyzer as shown in figure 3.

The second product is the NIRvascan extended range spectrophotometer that can measure in the range 1350-2150 nm which includes the 1950 nm absorption line of THC. Figure 4 shows this absorption line measured by the Nirvascan extended spectrophotometer.

The Nirvascan spectrophotometer can be calibrated for the THC absorption peak and a chemometric model can be produced which can predict the THC content of hempfood and oils. For more information about the Nirvascan spectrophotometer, refer to the following link:


In summary, the days of the past where hemp producers had no formal guidelines are coming to an end and the hemp market can benefit from the new regulations which could help it flourish.
