Effects of Roasting

When a red pepper is roasted, its intrinsic weight decreases from the loss of moisture content, so a roasted red pepper is slightly shriveled. However, the peppers should only roast for about five minutes. After this, you should put the roasted peppers into a food-quality plastic bag, close the top and leave them to steam until the flesh is cooked. This results in very little loss of nutrients. If anything, the nutrients of a roasted pepper become more concentrated 1.

Just half a cup of roasted red peppers provides you with nearly all your recommended daily amount of vitamin C. Vitamin C tends to be destroyed by cooking, but quick roasting methods will only reduce the vitamin content slightly. Roasted red peppers have not been cooked in water, which would leach away the vitamin C, so they retain much of the vitamin 1. The vitamin C content of 100 g of raw red pepper is 127.7 mg. The amount of vitamin C left in 100 g of red peppers that have been boiled is just 41.2 mg. Thanks to the reduced volume of roasted red peppers, their vitamin C content is actually higher than raw, at 162.8 mg per 100 g.

Provitamin A Carotenoids
