Gluten is a group of proteins found in certain grains, such as wheat, rye, and barley.  Sea vegetables are naturally gluten free because they don’t contain these proteins.  This led some food scientists to develop and evaluate a gluten free pasta made from seaweed (1)!  Consumers who tested the seaweed pasta said it tasted good and that it had less of the characteristic seaweed aroma after cooking.  Since we don’t process any gluten containing products at our facility, there’s also no chance for cross contamination.
