Lupulin should contain only a small amount of sand, vegetable 

 tissue and insect (aphidse) remnants. It is frequently adulterated with 

 sand. It deteriorates rapidly. Old material changes to an orange 

 yellow and the odor becomes heavier, almost cheese-like. Impurities 

 (sand, strobile tissue, leaf and stem fragments) are frequently excessive.
