Abstract: PROBLEM TO BE SOLVED: To provide a finely powdered carotenoid preparation controllable to have intended coloration effects and having a high bioavailability. SOLUTION: The production process comprises forming a molecular dispersion of carotenoid at an elevated temperature in a water-miscible volatile organic solvent optionally together with an emulsifier and/or an edible oil and adding a protective colloid to the solution. In this process, the hydrophilic solvent component is transferred to the water phase to form a hydrophobic phase of carotenoid as a nano-disperse phase and the obtained hydrosol is heat-treated at 40-90 deg.C. Then the solvent and water are removed from the heat-treated hydrosol to convert it into a water-dispersible dry powder.

Abstract: Filaments with a relative viscosity RV of 2.0 to 3.0 (measured at a concentration of 1 g of fibres per 100 ml in a 96 wt % sulphuric acid, based on polycaprolactam, obtainable by:(a) extruding a melt consisting essentially of caprolactam through a spinning nozzle to form caprolactam filaments;(b) cooling the filaments thus produced and (c) drawing the cooled filaments off at a rate of at least ¢3600 + 1250.(3.0-RV)!m/min, the polycaprolactam used being produced in the presence of at least one bicarboxylic acid from the group: C4-C10-alkane bicarboxylic acids, C5-C8-cycloalkane bicarboxylic acids, benzole and naphthaline bicarboxylic acids which may have up to two sulphonic acid groups and whose carboxylic acid groups are not adjacent, N-C1-C6-alkyl-N,N-di(C4-C10-alkane carboxylic acid)amine, 1,4-piperazine-di(C1-C10-alkane carboxylic acid), and a process for producing these filaments, their use for the production of fibers and flat products, and fibers and flat products made of these filaments.
