beta-Carotene content of Brazilian fortified pasta

This work was designed to verify the effective levels of beta-carotene fort ification of Brazilian commercial, popular spaghetti brands and assess the nutrient retention after cooking. Total carotenoid contents in the raw drie d pasta varied from 0.9 to 5.9 mu g/g. After separating what appeared to be degradation products, however, contents fell to not detectable to 3.8 mu g /g and two brands out of seven ranked below the minimum vitamin A value sta ted on the label. Cooking did not decrease the total carotenoid content. It is concluded that beta-carotene fortification of dried pasta can be valid, but analytical separation of beta-carotene is necessary to assess the true provitamin A. content.
