1. Characterization of Aeromonas, Enterobacteriaceae, Pseudomonas, Bacillus and Lactobacillus spontaneously growing to high numbers in milk, minced meat, fish or cheese
Sammanfattning : The spoilage flora of refrigerated raw and pasteurized milk was classified and identified by numerical phenotypic analysis. Isolations of bacteria were made at a defined spoilage stage, when the total aerobic count was 106-107 cfu per ml. The secondary flora of ripened Swedish and Norwegian cheeses was investigated by numerical analysis. LÄS MER
2. 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
3. Structure-Performance Relations of Oxygen Barriers for Food Packaging
Sammanfattning : Food packaging should ensure the safety and quality of food, minimize spoilage and provide an easy way of storing and handling it. Barrier coatings are generally used to meet the demands placed on fibre-based food packages, as these have the ability to regulate the amount of gases that can enter them. LÄS MER
4. Carrot Juice Processing - Effects on Various Quality Aspects
Sammanfattning : Carrots are a cold-weather crop well suited for cultivation in the south of Sweden. Carrots are generally rather inexpensive, with a market price below € 1 /kg (Sweden, 2003), whereas fresh carrot juice has a price of around € 5 /kg. LÄS MER
5. Solar Assisted Pervaporation : A process for the concentration of fruit juices in membrane pouches with solar energy
Sammanfattning : Drying has been used for thousands of years to preserve foods. One of the first methods used was open air sun drying which exposes foods directly to solar radiation and ambient air. This method is still used today around the world but it remains underdeveloped on a small-scale for two main reasons. LÄS MER
