4. 2. Lactic acid bacteria fermentations in oat-based suspensions

   Author : Olof Mårtensson; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; beta-glucans; probiotics; prebiotics; bacterial survival; Food and drink technology; Livsmedelsteknik; oats; ropiness; lactic acid bacteria; ropy;

   Abstract : This thesis deals with the fermentation characteristics of lactic acid bacteria (LAB) in oat-based suspensions, with formulation work of fermented products based on oat and with nutritional studies of these products. Changes in structure in terms of viscosity and ropiness were studied when exopolysaccharide (EPS)-producing LAB strains, namely, Lactobacillus delbrueckii subsp. READ MORE

5. 3. Dietary Fibre in Fermented Oats and Barley

   Author : Adele Lambo; Avdelningen för livsmedel och läkemedel; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Näringslära; Nutrition; short-chain fatty acids ; exopolysaccharides; fermentation; barley; oats; Dietary fibre polysaccharides; cholesterol ;

   Abstract : The physiological characteristics of native and bacterial exopolysaccharides (EPS) in oats and barley-based fermented products were studied in relation to the physico-chemical properties. Article I presents a parallel-randomized double blind clinical trial using a dairy-based product (control), an oat-based product (fermented with V2, which is a mixture (1:1) of Lactobacillus delbrueckii subsp.

   Abstract : The lactic acid bacterium, Streptococcus thermophilus, is used in the dairy industry in mixed cultures with Lactobacillus delbrueckii subsp. bulgaricus for the production of yoghurt. Many strains of S. thermophilus produce exopolysaccharides (EPSs) which affect the texture and viscosity of fermented food products. READ MORE
