Background. Linear programming has been used extensively as a tool for nutritional recommendations. Extending the methodology to food formulation presents new challenges, since not all combinations of nutritious ingredients will produce an acceptable food. Furthermore, it would help in implementation and in ensuring the feasibility of the suggested recommendations. Objective. To extend the previou
Abstract in UndeterminedSoil microbes constitute an important control on nitrogen (N) turnover and retention in arctic ecosystems where N availability is the main constraint on primary production. Ectomycorrhizal (ECM) symbioses may facilitate plant competition for the specific N pools available in various arctic ecosystems. We report here our study on the N uptake patterns of coexisting plants an
Colorectal cancer is the third most common type of cancer, and the second leading cause of cancer-related deaths in the Western world. Chronic inflammation, such as inflammatory bowel diseases (IBD), increases the risk of cancer. Cysteinyl leukotrienes are pro-inflammatory mediators that are involved in IBD. They are ligands to the G-protein coupled receptors CysLT1R and CysLT2R, of which CysLT1R
Spatial Data Infrastructures (SDIs) have been identified essential for environmental management and development activities around the world. Meanwhile, development of frameworks to monitor and evaluate SDIs is currently an important research area. This study proposes Balanced Scorecard (BSC) as a framework for evaluation and monitoring the implementation of SDIs. The concept and advantages of BSC
The purpose of this study was to evaluate the effect of prolonged heat processing (180 min at 50-80 degrees C) on the functional and theological properties of pectin, derived from olive mill wastewater (OMW). It was shown that a low temperature blanching of OMW at 60 degrees C, activates endogenous pectin methyl esterase and promotes demethylation, despite the high concentration of phenols. Activa
The objective of this study was to investigate how the properties of the serum phase, including ionic strength, protein content and specific milk salts, influence the whipping time of unhomogenised cream. This study showed that decreasing the protein content of the serum phase in cream resulted in shorter whipping time. However, addition of UF permeate to both deproteinated and proteinated creams
A microscopic method was developed to detect pressure thresholds for gas outflow and solution impregnation during vacuum impregnation of plant materials. Raw materials with different porosities (apple and spinach) were impregnated with an isotonic sucrose solution at a minimum pressure of 150 mbar. An automatic vacuum controller system (AVCS) was used to control the pressure during vacuum impregna
BackgroundImprovement of traditional methods for dietary assessment is necessary, especially in rural areas where it is more difficult to succeed with self-reporting methods. This study presents and validates a method for improving accuracy when measuring food and nutrient intake of individuals in rural areas. It is called the “Food photography 24-h recall method” (FP 24-hR) and is a modified
Chymosin-induced gelation properties of the milk of around 400 Swedish Red dairy cows was investigated with the aim of identifying genetic protein variants that influence chymosin-induced gelation for optimisation of cheese milk through breeding practices. The variation in chymosin-induced gelation properties was shown to be large in the milk of Swedish Red and there was a high frequency of cows p
At the close of the Fourth International Polar Year, we take stock of the ecological consequences of recent climate change in the Arctic, focusing on effects at population, community, and ecosystem scales. Despite the buffering effect of landscape heterogeneity, Arctic ecosystems and the trophic relationships that structure them have been severely perturbed. These rapid changes may be a bellwether
Plant functional response groups (PFGs) are now widely established as a tool to investigate plant-environment relationships. Different statistical methods to form PFGs are used in the literature. One way is to derive emergent groups by classifying species based on correlation of biological attributes and subjecting these groups to tests of response to environmental variables. Another way is to sea
The spin and configurational structure of excited states of Cd-127, the two-proton and three-neutron hole neighbor of Sn-132, has been studied. An isomeric state with a half-life of 17.5(3) mu s was populated in the fragmentation of a Xe-136 beam on a Be-9 target at a beam energy of 750 MeV/u. Time distributions of the delayed gamma transitions and gamma gamma coincidence relations were exploited
Zeaxanthin is a carotenoid produced by plants and has been associated with protection of the photosynthetic machinery under light stress and, together with lutein, in protection of the central retina of the eye. Zeaxanthin levels in blood plasma have been negatively correlated to the development of AMD (age-related macular degeneration) (Gale et al, 2003). Under normal conditions, plants have a lo
Numerous products from the food industry contain fruit and/or berries, in the form of fillings or ingredients, e. g. in yoghurt, some bread products/cereal products, ice cream, etc. In order to produce these ingredients and improve their characteristics, many processing techniques are available. This thesis focuses on dehydration methods that take into account the fragile and complex cellular tiss
