Often in a list of ingredients you will see "spor av..." which means "traces of...". In this case it appears to mean that trace elements of some minerals and vitamins can be found.

microelement, micronutrient, trace element, trace nutrient;

-- these are the options in the L&H Technical dictionary (Danish -English)

Oxford Dictionary of Food and Nutrition distinguishes them: Micronutrients are Vitamins and minerals needed in very small amounts (micrograms or milligrams per day)

Trace minerals are mineral salts required in the diet in small amounts (parts per million)

race elements is referred to trace minerals (but the expression is definitely used in that context.) I think the point is that they may not all strictly be elements.
