Chemical composition of silver - Seasonal fluctuations
The aim of the study was to examine the amount of nutrients, minerals and trace elements in oats by season to assess when it is best to harvest them from a nutritional point of view. Samples were taken at two locations, Tjaldanes by Saurbær in Dalasýsla and Herdísarvík by Selvogur in Reykjanes in the period from October 2011 to April 2013.
Seasonal fluctuations were detected in the content of nutrients in silver in both Herdísarvík and Tjaldanes and then followed the same process. In early spring, fiber, protein, fat, ash and water levels peaked. Measurements also indicated seasonal fluctuations in some of the minerals and trace elements measured; potassium, phosphorus, iodine, selenium, cadmium and lead. Heavy metals were within the limit limits with the exception of cadmium in winter.
