Antifungal activity of chitosan/chitooligosaccharides alone and in combination with chemical fungicides against fungal pathogens
(PhD Thesis;2013:12, Doctoral thesis, 2013)Botrytis cinerea Pers. ex Fr. is an economically important pathogen causing gray mold in over 200 plants species worldwide, including strawberry (Fragaria × ananassa). In Norway, gray mold is economically the most important ... -
Bruk av laktase og standardisert melk til produksjon av Cottage Cheese
(Master thesis, 2015-07-01)Norwegian: Oppgaven omhandler småskalaproduksjon av Cottage Cheese ved bruk av laktase og standardisert melk. Det ble undersøkt effekt av 3 forsøksfaktorer på sammensetning og kvalitet til Cottage Cheese. Målet var å oppnå ... -
Characterization of fecal lactic acid bacteria isolated from healthy Ethiopian infants : bacteriocin production and antibiotic suscepebility
(PhD Thesis;2011:55, Doctoral thesis, 2011)In this thesis lactic acid bacteria (LAB) were isolated from fecal samples of healthy Ethiopian infants, identified to species level, screened for bacteriocin production and tested for antibiotic susceptibility. Enterococci ... -
Consumer perception and acceptance of calorie-reduced dairy products
(PhD Thesis;2010:03, Doctoral thesis, 2010)This thesis is a part of the research project ‘‘Low energy products and consumer preferences”, financed by the Research Council of Norway (NFR) through Grant 167928/I10. The thesis is based on three experiments. Consumers’ ... -
Control of cheese quality – strategies and methods for delivery of consistent sensory product quality at the point of consumption
(PhD Thesis;2011:68, Doctoral thesis, 2011)An effective approach to quality control is an important issue for a food producer, as consumers expect consistent delivery of products. Two important strategies for control of food product end quality was discussed in ... -
Identification of androstenone sensitive subjects and their evaluation of different androstenone and skatole tainted meat products
(PhD Thesis;2011:12, Doctoral thesis, 2011)Castration of entire male pigs is widely used in Norway to prevent the unpleasant odour/flavour that may occur in meat from boars. Castration of entire male pigs is expected to be prohibited in Norway (and in Europe) in ... -
In vitro digestion of caprine whey proteins by human gastrointestinal juices : Effect of whey hydrolysates and peptides on in vitro cell responses
(PhD Thesis;2011:70, Doctoral thesis, 2011)The objectives of this thesis were to characterise human gastrointestinal juices, to identify peptides produced after in vitro digestion of whey proteins by these juices, and to screen for immunomodulating properties of ... -
Kefir and kefir grains : diversity of chemical properties and microflora
(PhD Thesis;2012:30, Doctoral thesis, 2012)Kefir grains contain bacteria and yeasts embedded in a protein and polysaccharide matrix. They constitute the primary starter culture for kefir, a fermented milk drink with a complex sensory profile containing high amounts ... -
Lactobacillus sakei metabolism and diversity
(PhD Thesis;2010:21, Doctoral thesis, 2010)Lactic acid bacteria are associated with food fermentation, acidification and preservation. Lactobacillus sakei is an industrially important species mainly due to its ability to ferment and preserve meat. It is used as ... -
Minimizing photooxidation in dairy products by tailor made light barrier properties in packaging materials
(PhD Thesis;2011:47, Doctoral thesis, 2011)Photooxidation is one of the major causes of food quality deterioration. Packaging is a common tool to protect against light and consequently prolong the shelf life of food. Transparent packaging materials are being widely ... -
Mitochondrial oxygen consumption and myoglobin redox stability in beef
(PhD Thesis;2012:14, Doctoral thesis, 2012)Myoglobin is the main pigment in meat and exists in three predominant states; deoxymyoglobin (DMb), oxymyoglobin (OMb), and metmyoglobin (MMb). The different myoglobin states are dependent on the production of mitochondrial ... -
Multi-block methods for investigating consumer acceptance of food
(PhD Thesis;2013:67, Doctoral thesis, 2013)Today's researchers easily gather large amounts of data of different origin and type. In sensory and consumer studies the objective is the collection of data to better understand consumer behavior in the market. Statistical ... -
Natural genetic transformation: development of a new genetic tool for Streptococcus thermophilus
(PhD Thesis;2010:16, Doctoral thesis, 2010)Lactic acid bacteria (LAB) have been used in fermentation of foods for hundreds or even thousands of years. During the last decade the genome sequences of a number of commercially important LAB species and strains have ... -
Quality changes in lamb/sheep and beef meat with emphasis on its colour and flavour
(Doctoral thesis, 2018)The term known as meat quality is related to complex biochemical processes and changes that occur in the animal tissue before and after slaughtering. From an analytical point of view, the more factors describing meat quality ... -
Studies on bacteriophages infecting lactic acid bacteria of industrial food fermentations
(PhD Thesis;2012:17, Doctoral thesis, 2012)Industrial food fermentations by lactic acid bacteria (LAB) are of great practical and economic importance. Bacteriophages (phages; bacterial viruses) infecting LAB can negatively affect quality, safety and value of the ...
