Quality changes in lamb/sheep and beef meat related to oxidative processes in muscle systems
(PhD Thesis;2015:77, Doctoral thesis, 2020-11-10)The oxidative processes in meat post mortem maintain the formation of free radicals. Behavior of reactive oxygen species is closely related to the energy metabolism of the muscle cell, mitochondrial activity and efficiency ... -
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 ... -
Quality goat milk for rennet coagualted cheese
(Master thesis, 2012-05-30)The differences in milk quality between the αS1-CN genotypes of goats have been studied in different goat breeds in several countries. It is in general accepted that the cheese making properties of the high αS1-CN variants ... -
Quality of fruits and purees of strawberry as affwcted by genotype, maturity and processing
(Master thesis, 2013-09-10)Jordbær (Fragaria X ananassa) inneholder et bredt spekter av næringsstoffer og bioaktive forbindelser. I denne avhandlingen var hovedfokuset på antocyaniner (røde pigmenter), aktivitet av polyfenoler oksidase (PPO) (et ... -
Quality of Norwegian goat milk for cheese production
(PhD Thesis;2016:19, Doctoral thesis, 2020-11-19)Norwegian goat milk has faced a number of challenges related to the quality of the milk. These challenges have been particularly related to poor rennet coagulation properties and offflavours. The aim of the project "Quality ... -
Quantitative and qualitative analyses of cyanopeptides in crayfish using liquid chromatography – mass spectrometry
(Master thesis, 2019)Microcystins are hepatotoxic (liver toxic) heptapeptides produced by cyanobacteria. These compounds can occur in drinking water, recreational water and food originating from waterbodies. The compounds are highly toxic and ... -
Quantitative and qualitative characterisation of the microbial composition of fresh and expired chicken meat, chilling tunnel, and its variation between productions
(Master thesis, 2022)Achieving a sustainable future is a complex task, of which reducing food waste is an important facet. The reported food waste in 2019 per capita in Norway was 78 kg, of which 55% was at consumer level. Chicken meat is ... -
Quantitative determination of ethyl glucuronide and ethyl sulfate in post-mortem blood using Hybrid-SPE-PPT and UHPLC–MS/MS
(Master thesis, 2015-12-03)Background: Alcohol misuse is associated with significant morbidity and mortality. Ethyl glucuronide (EtG) and Ethyl sulfate (EtS) are direct ethanol metabolites and powerful biomarkers for previous alcohol consumption. ... -
Quorum sensing circuits in Pseudomonas aeruginosa regulate N2O reduction
(Master thesis, 2016)Many bacteria respire in the absence of oxygen through reduction of nitrogen oxides (NOx) in the process called denitrification. Denitrification is the main greenhouse gas emitter by its release of N2O when high amounts ... -
Quorum sensing in the opportunistic pathogen Pseudomonas aeruginosa regulates N2O reduction
(Master thesis, 2019)Through a process called denitrification, bacteria can respire with the use of as terminal electron acceptors instead of oxygen. An intermediate of the denitrification process, nitrous oxide (N2O), often escapes to the ... -
Rapid and non-destructive analysis of intact potato tubers
(Master thesis, 2013-08-26)Abstract: The purpose of this study was to study and develop NIR spectroscopy for the prediction of dry matter content in intact unpeeled potato tubers. The techniques ability to measure dry matter content was also ... -
Rational engineering of a family 6 glycoside hydrolase
(Master thesis, 2017)Plant-based lignocellulosic biomass represents a significant global reserve of organic renewable energy, and is considered to have high potential to replace substantial portions of fossil-fuel dependency. Sugars derived ... -
Recognizing plasmid-reads by machine learning and K-mer statistics
(Master thesis, 2019)The aim of this project was to investigate to what extent some machine learning methods are able to classify chromosome reads from plasmid reads based on K-mer statistics. Both short Illumina HiSeq 2500 reads and medium-length ... -
