Candida utilis (torula yeast) is the most widely used yeast as an animal feed supplement due to its high content of B vitamin, minerals and amino acids, therefore, in order to use it as food, studies have been carried out to increase its growth rate and production, highlighting the use of magnetic fields. This paper constitutes a review of the main characteristics of this yeast, its use as an alternative food worldwide and in Cuba, as well as the effect of the application of magnetic fields on its growth. The results of the review carried out show that Candida utilis is used in the production of unicellular protein, due to its ability to use a variety of carbon sources, being able to replace traditional protein sources. Although several investigations are reported in which the application of a static magnetic field causes an increase in the growth of fungi and yeasts, few reports were found in relation to the torula yeast, even so, it is found that low-intensity magnetic fields increase the cell biomass of this yeast.

Keywords : Candida utilis; torula yeast; unicellular protein; alternative food; magnetic fields.
