proper conditions for producing crude beta-galactosidase from waste materials were de-termined. this enzyme is to be used in the production of lactose-hydrolyzed milk. whey permeate was used as a basic medium. twenty seven treatments were developed by 3 vary-ing factors of: yeast extract (1, 2, and 3 %), wheat steep liquor (1, 2, and 3 %), and whey powder (0.5, 1, and 1.5 %). crude enzyme extra...

This research was focused on whey ultrafiltration permeate (UF) fermentation by genetically unmodified (wild) organisms. We chose five classical Propionibacterium (Prb) strains which are attributed to the dairy subclass. The optimal temperature for Prb growth is around 28-30°C, however, energy saving purposes aim of this study observe organic acid, especially propionic acid (PA) and biomass pro...

The objective of this research was to evaluate the suitability whey permeate powder for ice cream. Three white mixes were formulated with equivalent total solids, fat, and carbohydrates, but different concentrations lactose added sugar. Vanilla creams contained either reduced (RL, 3.8% 17% sugar), standard (SL, 5.8%; 15%), or high (HL, 7.8%; 13%). Trained panelists evaluated 8 body texture, 6 f...
