Extreme halophilic : carotenoids characterization and antioxidant properties.

Important marine microorganisms are resources of renewable energy that may face global population growth and needs. The application of biomass metabolites, such as carotenoids and their derivatives, may solve some agro-food health problems. Herein, a new halophilic producing carotenoid was screened from a Tunisian solar Saltworks (Sfax).

Antihyperlipidemic and antioxidant effects of feather protein hydrolysate in high-fat diet-fed mice.

The hyperlipidemia is a serious health problem that increases the risk of many complications including cardiovascular disease. This study aims to evaluate the possible antihyperlipidemic effects of the feather protein hydrolysate (FPH) in a mice fed with a high-fat diet (HFD)-fed mice during 5 weeks. The FPH administration improved dose-dependent lipid profile, as well as the liver and renal dysfunction indices in hyperlipidemic mice.

Encapsulation of carotenoids extracted from halophilic Archaea in oil-in-water (O/W) micro- and nano-emulsions.

Carotenoids extracted from halophilc Archaea have potential health benefits. Their poor water-solubility and low bioavailability is a challenge to their incorporation into foods. The aim of this work was the carotenoids encapsulation into two oil-in-water (O/W) dispersions, to increase their use as functional food applications.
