PROCESS FOR OBTAINING A SOLUBLE SINGLE-CELL PROTEIN (PRO60) USABLE IN VARIOUS FOOD MATRICES

Abstract

The present invention relates to a novel fermentation, extraction, and purification process for obtaining single-cell protein for use in the food industry, using a particular strain of Kluyveromyces marxianus, designated KMPROTEO 1. This process yields a product consisting of a single-cell protein powder with a protein content equal to or greater than 60%, which is highly bioavailable and, being soluble, allows its inclusion in different food matrices without changing the formulation or profile of the product to which it is added. This product has been named "PRO60". The process disclosed herein includes a description of the aerobic fermentation of the Kluyveromyces marxianus strain, designated KMPROTEO 1, as well as the use of the resulting ingredient or final product in addition to certain preferred food matrices.
