Norway – Analyzes of nutrients, heavy metals and mycotoxins in cereal products 2021


The Institute of Marine Research (HI) has, on behalf of the Norwegian Food Safety Authority, performed analyzes of nutrients, heavy metals and mycotoxins in grain products. The purpose of the project “Analyzes of nutrients, heavy metals and mycotoxins in grain products” is to obtain nutrient values ​​for the Food Table and control the products for foreign substances.

What we investigated:
  • The analyzed products are; oatmeal, organic oatmeal, sifted wheat flour, spelled wheat flour, organic wheat flour, whole wheat flour, sifted rye flour, whole rye flour, finely ground barley flour and bran.
  • The producers: AXA, Kolonihagen, Møllerens and Regal.
  • A total of 45 aggregate samples. Each sample consisted of three different batches from each manufacturer.
Period: The analyzes were performed in the period November-December 2019 (sample 1), and in August-September 2020 (sample 2) and five grain products in February 2021 (sample 3).
What we were looking for: The project has provided analysis data for the content of nutrients and foreign substances in grain products from the grocery trade.

 The project has provided analytical values ​​for ash, protein, fat, fatty acids, sugars, starch, dietary fiber, β -carotene, thiamine (vitamin B1), riboflavin (vitamin B2), niacin (vitamin B3), pyridoxine (B6), folate, vitamin C , vitamin E, vitamin K1, vitamin K2, calcium, magnesium, sodium, potassium, phosphorus, iron, zinc, selenium, iodine, arsenic, cadmium, lead and mercury, and the mycotoxins deoxynivalenol (DON), zearalenone, T2 HT2 and enniatin for 40 grain products. The grain products in sample 3 (5 products) were only analyzed for fat, protein, ash, starch and dietary fiber.

What we found: The results show that the levels of the heavy metals in the cereal products analyzed are below the limit values ​​that apply to arsenic, lead, cadmium, mercury and mycotoxins.

The results show a higher content of dietary fiber in Norwegian grain products than before. This can be explained by the use of an analysis method (AOAC 2009.1) that includes several dietary fiber compounds.

The Norwegian Food Safety Authority will inform affected companies about the analysis project.
