Abstract
Quality parameters of saffron may be determined by physical, chemical and organoleptic tests. Based on a study of several samples of saffron, the characteristic properties for assessing quality have been reported as dark red colour; thread like filaments (1-2 cm long) spreading like a trumpet at one end; strong and aromatic, slightly iodinated odour; bitter and slightly pungent taste; colour diffusion in water, when placed on surface of warm water the stigma expanding immediately and colour diffusing slowly; and floral waste, 15% (max.). The chemical parameters are: moisture and volatiles (103 degree C), 14% (max.) by wt; total ash, 8% (max.) by wt.; ash insoluble in HCl, 1.5% (max.) by wt.; aqueous extract, 55-65%; total N, 1.5-3.0%; colouring power E1 at 440 nm, min. 100; TLC using 80% ethanol for extraction and butanol/acetic acid/water (4:1:1) as solvent for elution, 3 intense characteristic spots; and reaction with 0.5% solution of diphenyl amine in sulphuric acid, deep blue colour turning brownish red.
