Abstract
Autolysis of yeast slurries is accelerated by the presence of thiamine and/or pyridoxine and by gradually raising the temperature of the yeast slurry to the incubation temperature over a period of time of from about 20 to about 180 minutes.
Claims13
In a process for autolyzing yeasts wherein a yeast slurry is incubated at a temperature of from about 40.degree. to about 60.degree. C. to solubilize the yeast cell materials, the improvement comprising incubating the yeast slurry for from about 2 to about 16 hours in admixture with an additive selected from the group consisting of thiamine, pyridoxine, and a combination of thiamine and pyridoxine at a concentration of at least 0.01 weight percent.
A process for autolyzing an aqueous yeast slurry comprising incubating the slurry at a temperature of from about 50 to about 55.degree. C. for about 2 to about 16 hours in admixture with from about 1 to about 6 weight percent salt, from about 0.05 to about 4 weight percent ethanol, from about 0.05 to about 3 weight percent dextrose, and an additive selected from the group consisting of thiamine, pyridoxine, and a combination of thiamine and pyridoxine at a concentration of at least 0.01 weight percent.
