Hydrophilic carotenoids: Surface properties and aggregation behavior of the potassium salt of the highly unsaturated diacid norbixin

The oft-claimed 'good' water solubility of the food color norbixin (3) could not be confirmed. In contrast, the potassium salt 5 of norbixin formed suitable dispersions. The surface and aggregation properties of salt 5 were investigated and compared with

NOVEL INTERMEDIATES FOR PREPARING NORBIXIN OR BIXIN ETHYL ESTER AND METHODS THEREOF

The present invention relates to a method for preparing a carotenoid compound, norbixin or bixin ethyl ester, from a novel intermediate compound. When using the novel intermediate compound, norbixin or bixin ethyl ester can be prepared in high yield through a simple process.

Thermal degradation kinetics of bixin in an aqueous model system

The kinetics of the thermal degradation of the natural cis carotenoid bixin in a water/ethanol (8:2) solution was studied as a function of temperature (70-125°C), using high-performance liquid chromatography. The curves for the decay of bixin and formation of products (e.g., di-cis and all-trans isomers and a C17 degradation compound) did not adjust well to a first-order rate law, but very good fits were obtained using a biexponential model. This mathematical modeling gave the rate constant values for the formation of the primary products from bixin, and the energy barrier for each step was obtained. The di-cis isomers were formed immediately (15 kcal/mol) together with the decay of bixin, followed by a slow consumption, indicating their role as reaction intermediates. In fact, the di-cis isomers could easily revert to bixin (Ea ≈ 3 kcal/mol) or yield the primary C17 degradation product, with an energy barrier of 6.5 kcal/mol. In turn, 24 kcal/mol was necessary for the Bix - all-trans step, explaining its slower formation.
