Important focus points in the chemical analytics (pesticide measurements, nutritional values, etc.) are the composition of raw materials and products in food processing and feed production and the changes in their quality and safety that occur during processing and storage, for example nutritional value, shelf life and stability.

Many chemical measurements are carried out at Matís as customer service, the most common are:

• General chemical analytics (protein, fat, salt, water, ash, etc.).
  Matís has accreditation from Swedac, sænsku faggildingastofunni á 12 almennum efnamælingum.
• Quality analysis of fish and fish products (TVN, Totox, rotamine, etc.).
• Analysis of mineral and trace elements. Contact: Natasa Desnica
  Minerals and trace elements are measured in food, feed and environmental samples. Matís is accredited by Swedac, the Swedish accreditation body, for a method for 9 metals in fish and fish oil, meat and milk.
• Pesticide analysis. Contact: Eydís Ylfa Erlendsdóttir
  At Matís, pesticide analysis are carried out in fruit, vegetables and cereals, the analytics are accredited by Swedac, the Swedish accreditation body. Matís has identified 192 pesticides. Pesticides are usually divided into 4 categories of insecticides, herbicides, fungicides and stimulants, but these are substances that control plant growth.
• Nutritional value for labeling.
  Matís can help you prepare a nutrition declaration (formerly called nutrition labeling). We advise you what materials need to be measured and how to take samples. If it is possible to calculate the nutritional value, we will take it on.
• You can get more information about food labeling on Matís' website here: Packaging labels - Matís (matis.is)
• The ÍSGEM database can be used for food labeling. Information about the database and its search can be found here: ÍSGEM
