| Research Abstract |
Deep green colord vegetables (leek, perilla, spinach, broccoli etc.) have a higher anti-lipoxygenase activity than those lighter green colored vegetable (cabbage, cucumber), nevertheless beans, mushrooms and garlic have more strong anti-lipoxygenase activity than vegetables. From those resuzts carotenoids in vegetagles were thought to work anti-lipoxygenase activity. Then lycopene from tomato and beta-carotene, lutein, violaxanthin and neoxanthin from spinach were used to ability in those other carotenoids at the same concentration and activity, in this order. The rerathion between structure of carotenoids and ionone ring and the number of duble bonds.
The changes of carotenoids pigments in the process of boiled cookin and first, and then neoxanthin, lutein and beta-carotene were oxidized after cooked with boiled water and 1% salt boiled water. The similar results were obtained during the 160ﾟC deep fryng.
From the above results, the xanthophylls such as ciolaxanthin, neoxanthin and to protect the oxidathion of beta-carotene.
