Saffron grades

Saffron is graded via laboratory measurement of crocin (colour), picrocrocin (taste), and safranal (fragrance) content.
Crocin: Crocin is a natural carotenoid chemical compound that is found in the flowers crocus and gardenia. It is the diester formed from the disaccharide gentiobiose and the dicarboxylic acid crocetin.
