the study of the colloidal properties of nano liposomes containing beta-carotene produced by thermal method
introduction : the encapsulation of nutraceuticals in lipid based carriers, such as liposomes, can lead to increasing of bio-active ingredients bioavailability and controlled release, maintaining their stability in different environmental conditions and increasing solubility of hydrophobic active ingredients in aqueous conditions. food grade liposomes are being increasingly used in food industr...
متن کاملBeta-carotene content of certain organs from two patients receiving high doses of beta-carotene.
We measured carotene in the livers of two patients receiving beta-carotene therapy for photosensitivity. In both patients, the amount of carotene was within reported ranges for patients on normal diets; no abnormal amounts of beta-carotene had accumulated in the livers after oral administration of large amounts of beta-carotene. Light-microscopic examination of the liver (specimen obtained at c...
متن کاملBeta-carotene and lung cancer*
Does beta-carotene increase, rather than decrease, human lung cancer rates? A large body of observational epidemiologic study has demonstrated that individuals who eat more fruits and vegetables rich in carotenoids and/or who have higher levels of serum betacarotene have a lower risk of cancer, particularly lung cancer. This inverse relationship has been particularly strong in lung cancer patie...
متن کاملBeta-carotene: the controversy continues.
The three beta-carotene intervention trials: the Beta Carotene and Retinol Efficacy Trial (CARET), Alpha-Tocopherol, Beta-Carotene Cancer Prevention Study (ATBC), and Physician's Health Study (PHS) have all pointed to a lack of effect of synthetic beta-carotene in decreasing cardiovascular disease or cancer risk in well-nourished populations. The potential contribution of beta-carotene suppleme...
متن کامل1,1,6-Trimethyl-l ,2-dihydronaphthalene (TDN): A Possible Degradation Product of Lutein and beta-Carotene*
Carotenoids are unstable compounds and are easily degraded to a variety of products in the presence of oxygen and light as well as at elevated temperatures. Ohloff (1972) hypothesised that carotenoids are precursors of aromatic compounds such as C13-norisoprenoids. Recently, several C13-norisoprenoids have been identified upon liberation from their bound forms in grapes and wines (Sefton et at....
