A process for obtaining beta -carotene. The present invention relates to a new process for the production of beta -carotene from submerged cultures of mucor fungi such as Blakeslea, Choanephora or Phycomyces by means of addition to the culture medium of lecithin in conjunction with pH control once fermentation has started, a process that includes a step of recovery of beta -carotene that allows a simplification in the process, an optimisation of the yield, along with an increase in the purification of the product.
