  1. 1. Fermentation as a Means of Optimizing the Glycaemic Index - Food Mechanisms and Metabolic Merits with Emphasis on Lactic Acid in Cereal Products

    University dissertation from Lund Institute of Technology

    Author : Elin Östman; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nutrition; starch; healthy human; fermentation; lactic acid; sourdough; cereal products; milk; glycaemic index; bread; Näringslära; diabetes; insulin response;

    Abstract : In current recommendations from FAO/WHO, foods that elicit low glycaemic responses and thus have low glycaemic indices (GIs) are advocated. The rationale for this recommendation is that low-GI diets have been shown to reduce risk factors for e.g. type II diabetes and cardiovascular disease. READ MORE

  2. 2. Lactic acid production: extractive fermentation in aqueous two-phase systems

    University dissertation from Department of Applied Microbiology, Lund University

    Author : Jordi Planes; [1998]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gel excludion chromatography; polyethylenimine; ethylene oxide propylene oxide; phase forming polymers; aqueous two-phase systems; extractive fermentation; Lactococcus; Lactobacillus; Mikrobiologi; bakteriologi; virologi; mykologi; bacteriology; virology; mycology; Microbiology;

    Abstract : There is an increased interest in the microbial production of lactic acid as a raw material for the synthesis of lactic acid polymers as biodegradable plastics. However, two factors limit the economical competitiveness of lactic acid production by microorganisms: lactic acid inhibition, which decreases both fermentation rate and the maximum lactic acid concentration, and the efficiency in the recovery of lactic acid.

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

    University dissertation from Olof Mårtensson Department of Biotechnology, Center for Chemistry and Chemical Engineering, Lund University

    Author : Olof Mårtensson; [2002]
    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. 5. Influence of Lactic Acid Fermentation on Enteropathogenic Bacteria. Growth Inhibition in Cereal Gruels and in Human Intestine

    University dissertation from Olof Mårtensson Department of Biotechnology, Center for Chemistry and Chemical Engineering, Lund University

    Author : Rose Kingamkono; [1997]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; intestinal mucosal permeability; enteropathogenic bacteria; enterotoxins; lactic acid fermentation;

    Abstract : Togwa, a lactic-fermented cereal gruel, is widely consumed in Tanzania as a soft drink or used as a complementary food for young children. Studies were conducted to evaluate the potential of togwa to inhibit growth of common enteropathogenic bacteria and heat-labile (LT) enterotoxin production. READ MORE
