1. Characterisation of Food Associated Bacteria by DNA based Methods, with Special Reference to Enterobacteriaceae
Sammanfattning : The presence of genes in food, encoding some virulence factors, was studied by PCR, and species of Enterobacteriaceae, associated with food, were studied by the DNA-based methods of TTGE, ribotyping and sequencing. The flora of fresh and chill-stored pork were analysed by a culture-independent approach, using specific amplification of 16S rRNA genes followed by cloning and sequencing. LÄS MER
2. Microbiological hygiene and biological control of leafy green vegetables
Sammanfattning : Fruit and vegetables are vital components of a healthy diet, and international strategies to encourage their consumption are in place (FAO/WHO, 2005). Ready-to-eat (RTE) leafy green vegetable products have exploded in popularity, and are a convenient and attractive way to add greens to the plate. LÄS MER
3. Fermented probiotic beverage based on quinoa : Functionality, hygiene, and health effects
Sammanfattning : White quinoa grains were used as a source of novel beneficial microorganisms and as a matrix for development of a fermented plant-based drink. Studies on the quinoa grain microbiota were performed by applying spontaneous fermentation to allow isolation of autochthonous Lactiplantibacillus strains with potential to be used as starter cultures.

4. Bacteriological Hygiene in the Production of Pasteurised Milk
Sammanfattning : Critical contamination sites and sources for the Gram-negative psychrotrophs (GNP) of the taxa Pseudomonas, Enterobacteriaceae and Aeromonas, and the Gram-positive spore-forming (GPS) species Bacillus cereus, have been traced in the production line of pasteurised milk. Samples of raw and pasteurised milk from different sampling sites along the line were collected. LÄS MER
5. Food Safety Learning in Home and Consumer Studies : Teachers' and Students' Perspectives
Sammanfattning : The aim of this thesis was to explore food safety as part of Home and consumer studies (HCS) education in Swedish compulsory school.Firstly, a nationwide web-based questionnaire was performed among HCS teachers to obtain an overall picture of their knowledge, behaviour and attitudes regarding food safety.
