Abstract: Method for the continuous preparation of beta -carotene solubilisates by brief heating of beta -carotene together with an emulsifier until solution takes place, rapid cooling of the homogeneous solution to below 100 DEG C by addition of water and subsequent adjustment of the required final concentrations of beta -carotene, which is characterised in that a suspension, which has been preheated to 20 to 80 DEG C, of 1 to 40% by weight beta -carotene in an emulsifier is pumped through a heating coil located in a heat-transfer oil, where the temperature in the solubilisation mixture is 120 to 180 DEG C and the residence time is 10 to 300 seconds, and the homogeneous solution is turbulently mixed in a mixing chamber with such quantities of water at 10 to 80 DEG C that a solubilisate containing 0.5 to 6% by weight beta -carotene is produced and is, where appropriate, further diluted to the required final concentration.
