Technology for the whole utilization of brewer's yeast in food industry.

A flexible scheme for the fractionation of brewer's yeast was developed. Th e procedure allows the production of different products such as: dry yeast flakes, dry yeast pills, yeast-extract based table sauce, yeast protein con centrates and soy-like sauce. The investment required for the processing of one ton per day is below 2 million dollars with an overall profitability h igher than 53%. Investment is recovered in 0.75 years. The production of fo od ingredients from yeast upgrades its biomass about 25 fold. Present proce dure is compared with other biomass fractionation processes taking into acc ount the utilization of all technological streams where the process becomes environmentally friendly since effluent production significantly lower tha n similar technologies.
