Abstract

Production of fermented functional foods containing micronutrients is required for their health beneficial properties. Impact of 11 process variables on vitamin B12 production in a dairy beverage containing propionic acid was investigated. Propionibacterium freudenreichii ssp. shermanii was applied in a 3-l fermentor in fed-batch fermentation system. The most suitable conditions for vitamin B12 production were achieved by 5% v/v inoculum size containing Propionibacterium freudenreichii (without Lactobacillus acidophilus) and continuous feeding of lactose with the rate of 0. 04 l/h at 36° C in a medium containing 25 g/l molasses, 10 g/l corn steep liquor, at pH=6. 5, after 96 h fermentation. Maximum vitamin concentration (30 mg/l) and productivity (7. 5 mg/l. day) were obtained in trial 9. Organoleptic properties of the fermented beverage were also acceptable for panelists and no significant difference was observed between samples and control during 6 days refrigerated storage.
