[Desugarization of egg white by microorganisms].

Glucose was eliminated from egg whites, using microorganisms, to prevent melanoidin formation which may damage the product. Desugarization was achieved by means of Acetobacter xylinum, Streptococcus lactis, Propionibacterium shermanii, Pr. petersonii and propionicacid cocci. Optimal conditions of desugarization were found, depending on the physiological characteristics of the above microorganisms. Propionibacterium shermanii may be well used to ferment a liquid egg white. These bacteria have no proteolytic properties and make no use of the egg white. They enrich the egg white with vitamin B12 and propionate, a preserving agent, during fermentation.
