  1. 1. Aroma and Flavor in Liquid Beet Sugar Processing

    Författare :Per Pihlsgård; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; liquid beet sugar; aroma release; liquid beet sugar process; electronic nose; aroma; sensory analysis; macromolecules; flavor; GC-MS; GC-olfactometry;

    Sammanfattning : Production of liquid beet sugar, a product of increasing importance for the food industry, involves many different compounds exhibiting aroma. Aroma compounds are introduced with the raw material, the sugar beets, but also formed as a result of sugar degradation (caramelization and Maillard reaction) or by contamination from process steps, such as adsorbents and ion exchangers.

  3. 2. Sustainability of the Swedish Sugar Sector : Assessment Tool Development and Case Study Appraisal

    Författare :Barry Ness; LUCSUS; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; integrated assessment; DPSIR; scale; sugar beet; sugar; Sustainability science; sustainability assessment; proximity analysis; Scania; Sweden;

    Sammanfattning : This thesis contributes to the development of tools and methods for assessing sustainability and applies them to an assessment of the Swedish sugar production system. The thesis’ aims are to compile an overview of the existing approaches for assessing sustainability, to suggest a method(s) for structuring and analyzing complex sustainability issues, and to appraise sustainability impacts from Swedish sugar production.

  4. 3. Application of Molecular Markers in Sugar Beet Breeding

    Författare :Annika Hjerdin Panagopoulos; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Växtbiokemi; Plant biochemistry; breeding; marker application; molecular markers; sugar beet;

    Sammanfattning : Around 1750 a German chemist discovered it to be possible to extract sugar crystals from beet juice. Since then, breeding and improved agricultural practices have increased the concentration of sucrose per root from around 4% to around 18%. LÄS MER

  5. 4. Molecular Breeding of Sugar Beet, Transformation, Transgene silencing, Virus and Herbicide resistance

    Författare :Marie Mannerlöf; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Agrobacterium tumefaciens; BNYVV; coat protein; CP4epsps; gene silencing; glyphosate; herbicide; rhizomania; transformation; sugar beet; Beta vulgaris L.; virus; Plant biochemistry; Växtbiokemi;

    Sammanfattning : The main objectives in sugar beet breeding, are to improve yield, quality and to develop disease resistance. The disease resistance may be developed either by conventional, or molecular breeding techniques. The molecular breeding techniques include, methods to genetically engineer plants for expression of introduced genes. LÄS MER

  7. 5. Alternative agriculture and rural development: A case study of sugar beet cultivation in Kenya

    Författare :Nicodemus Mandere; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Challenges; Prospects; Household income; Poverty; Sugar beet; Kenya; Alternative agriculture;

    Sammanfattning : Land use change has been observed to cause profound impacts on sustainability, particularly when the change is not well planned and co-coordinated. In Kenya the government is promoting diversification of crops to embrace high value crops and drought resistant crop varieties in efforts to reduce poverty in rural areas. LÄS MER
