  1. 21. Utilization of Wild Fruit in Mozambique – Drying of Vangueria infausta (African medlar)

    Författare :Eulália Chiau; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vangueria infausta; drying; maltodextrin; sucrose; softener; toughness; solar-assisted pervaporation; aroma; crystallization; water activity;

    Sammanfattning : Vangueria infausta (African medlar) is a wild fruit found in southern and central Mozambique. The ripe fruit has a leathery skin enclosing three to five seeds embedded in a soft pulp that tastes like apple. It plays an important role in the diet of the rural population and has the potential for commercial use. LÄS MER

  3. 22. Effects of non-fish based raw materials on the fish muscle quality of salmonids

    Författare :Jinfeng Pan; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Salmonids are considered as fatty fish and a healthy food. They are characterized by a high proportion of n-3 long chain polyunsaturated fatty acids (n-3 LCPUFA). There is great interest in producing high-quality salmonids with a reduced use of fish-based materials and a challenge to adjust feeds towards more sustainable. LÄS MER

  4. 23. Studies on the enantioselective disposition of amlodipine : A challenge in bioanalysis

    Författare :Martin Josefsson; Martin Ahnoff; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : To study the disposition of the enantiomers of the calcium channel blocker amlodipine in human plasma, an enantioselective high performance liquid chromatographic (HPLC) assay was developed. Several HPLC techniques such as chiral ion-pair forming, chiral derivatisation and direct separation on chiral columns were evaluated. LÄS MER

  5. 24. Metabolic engineering of S. cerevisiae for the production of flavonoids

    Författare :Marta Tous Mohedano; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; microbial cell factories; high-value products; sustainability; cinnamic acid; plant natural products; Genetic engineering; yeast;

    Sammanfattning : The interest in the production of natural products such as flavonoids has been increasing during the last decade. Flavonoids have several attractive bioactivities including antitumoral, antioxidant or antimicrobial properties. To produce these high-value products, we usually recur to chemical synthesis or plant extraction. LÄS MER

  7. 25. The Story of Phosphorus : Sustainability implications of global phosphorus scarcity for food security

    Författare :Dana Cordell; Stuart White; Jan-Olof Drangert; Julie Wilk; Johan Rockström; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; global phosphorus scarcity; peak phosphorus; global food security; sustainable resource use; food production and consumption system; transdisciplinary; systems thinking; global fosforbrist; peak fosfor; global matsäkerhet; hållbar resursanvändning; system för produktion och konsumtion av mat; transdisciplinaritet; systemtänkande; Water in nature and society; Vatten i natur och samhälle;

    Sammanfattning : The story of phosphorus began with the search for the philosopher’s stone, and centuries later the critical role of phosphorus in soil fertility and crop growth was highlighted. Eventually, phosphorus was implicated in the global environmental challenge of eutrophication. LÄS MER
