Picrocrocin
IUPAC 名称
2,6,6-trimethyl-4-{[3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}cyclohex-1-ene-1-carbaldehyde
描述
Isolated from saffron (stamens of Crocus sativus). Food colour and flavouring ingredient
During the drying process picrocrocin liberates the aglycone (HTCC, C10H16O2) due to the action of the enzyme glucosidase. The aglycone is then transformed to safranal by dehydration. Picrocrocin is a degradation product of the carotenoid zeaxanthin.[citation needed]; Picrocrocin is a glycoside formed from glucose and safranal. It is found in the spice saffron, which comes from the crocus flower. Picrocrocin has a bitter taste and is the chemical most responsible for the taste of saffron.; ; It is believed that picrocrocin is a degradation product of the carotenoid zeaxanthin .; Picrocrocin is a monoterpene glycoside precursor of safranal. It is found in the spice saffron, which comes from the crocus flower. Picrocrocin has a bitter taste and is the chemical most responsible for the taste of saffron.
