1. Utilization of Andean grain flours in the development of wheat flour dough
Sammanfattning : Bread dough was studied in relation to three Andean grain flours, quinoa (Chenopodium quinoa), amaranth (Amaranthus caudatus) and canahua (Chenopodium pallidicaule), as partial replacements for wheat flour with the perspectives of dough and breadmaking. This thesis deals with the understanding of both dough as a complex system, consisting of various water-filled polymers, and dough as a viscoelastic material, with different responses to deformations, in order to contribute to possibilities for improvements in dough analysis and development of novel products.

2. 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.

3. Determination of folate for food composition data : development and improvement of analytical methods
Sammanfattning : Folate is B vitamin that is required for maintaining normal blood status. Recommendations on daily intake are based on information on blood folate status in relation to folate intake and bioavailability. Folate intake from a diet is evaluated by folate content in the food consumed. LÄS MER
4. Nanorheological Studies of Caseins
Sammanfattning : To be able to improve the quality of dairy products and dairy processes, knowledge of casein molecules, casein micelles and casein aggregates is important. The rheological properties of casein products, casein gels and adsorbed layers of casein, have been widely investigated. LÄS MER
5. On the Extraction of Essential Oils by Supercritical Carbon Dioxide and its Influence on the Mesomorphic Phase Structures
Sammanfattning : A comparison of essential oils from leaves of Eucalyptus camaldulensis Dehn. obtained by hydrodistillation (HD) and supercritical carbon dioxide (SC-CO2) extraction is presented. Selected major components of the oils showed a predominance of higher molecular weight components in the SC-CO2 extracts than in those obtained by HD. LÄS MER
