To take advantage of high prices, saffron floral parts and foreign materials such as dyed corn silk, safflower petals, other flowers, wax, sugar, fat, or even inorganic compounds are sometimes added to make the final product heavier. The most common practice is to include the yellow and white colored style along with the stigma threads. However, these practices decrease the quality and price of saffron spice. Saffron quality depends on the level of three compounds; crocin (for color), picrocrocin (for flavor), and safranal (for aroma). These three compounds are concentrated in the red-colored part of the stigma threads; thus, adding any other flower parts or external materials decreases the saffron quality and market price. The International Organization for Standardization (ISO) sets the standard of saffron quality using three categories based on these three compounds' laboratory analysis.",
