Sesame lignans have multiple functions and were recently reported to have potential as sources of phytoestrogens. Sesame oils used in Taiwan are expelled from roasted sesame seeds with dark colour and strong flavour. This study analyzed lignan contents of 14 brands of sesame oils, and found their mean of total lignans to be 11.5 mg/g; 82% and 15% of the lignans were sesamin, and sesamolin, respectively. Sesamol contents were relatively higher in those with darker colour. In use as a cooking oil, heating at 180 C for 4 min did not change the content of lignans, but the level of sesamol increased after heating at 180 C for 20 min. Heating at 200 C for 20 min caused a significant loss of sesamolin and sesamol. From our calculation, ingestion of 10 g of sesame oil is adequate to provide the level of lignans
that might benefit cardiovascular health, as found by other studies. Cooking at temperatures above 200 C will cause loss of some lignans, but sesamin, a source of phytoestrogen, is relatively heat-stable.

Oils used in Taiwan are expelled from roasted sesame seeds with dark colour and strong flavour. This study analyzed lignan. Contents of 14 brands of, sesame oils and found their mean of total lignans to be 11.5 mg / g; 82% and 15% of the lignans. Were sesamin and sesamolin, respectively. Sesamol, contents were relatively higher in those with darker colour. In use as. A cooking oil heating at, 180 C for 4 min did not change the content of lignans but the, level of sesamol increased after. Heating at 180 C for 20 min. Heating at 200 C for 20 min caused a significant loss of sesamolin and sesamol. From, our calculation. Ingestion of 10 g of sesame oil is adequate to provide the level of lignans.That might benefit cardiovascular health as found, by other studies. Cooking at temperatures above 200 C will cause loss. Of some, sesamin lignans but, source of, a phytoestrogen is relatively heat-stable.2.
