PRODUCTION OF YEAST PRODUCT FROM LACTOSE-CONTAINING SUBSTRATES

摘要

A modified cultured yeast product for human and animal consumption is produced by combining yeast cream and yeast centrate to produce a cream/centrate mixture, autolyzing the mixture, inactivating by heating the mixture and optionally drying. After autolysis, hydrolysis may be carried out by the use of acids, alkalis or enzymes. The yeast cream and yeast centrate are preferably produced by culturing Kluveromyces marxianus or Candida intermedia in a whey permeate and separating yeast cream and yeast centrate from the cultured whey permeate. The cream and centrate are combined such that the ratio of total solids of cream to total solids of centrate is between about 0.3 and 1.6 and preferably about 1:1.
