Abstract: The present invention relates to a method for producing carotenoid solutions in an oil suitable for food. In particular, the invention relates to a method for dissolving a carotenoid, in particular astaxanthin, in an oil suitable for food by heating a suspension of the carotenoid, especially astaxanthin, in the oil and then rapidly cooling (quenching) the obtained solution. The method comprises the following steps: i. providing a suspension of the carotenoid in an oil suitable for food; ii. continuously heating a flow of the carotenoid suspension, wherein a hot carotenoid solution is obtained; and iii. continuously rapidly cooling the hot carotenoid solution, wherein the carotenoid suspension is conducted over a heated heat exchanger surface as a thin liquid film in order to continuously heat the carotenoid suspension.

Abstract: The invention relates to a method for obtaining cyclododecatriene (CDT) from a solution containing CDT and high-boiling components such as a deactivated catalyst and polymers. Said solution is supplied to a preheater and heated, and is then relaxed over a downstream pressure maintaining device, and the two-phase mixture obtained is supplied to a spiral tube evaporator where the CDT content of the liquid phase is reduced by partial evaporation and a gaseous product flow with an increased CDT concentration is derived.
