  1. 1. Recycling plant nutrients from waste and by-products : a life cycle perspective

    Författare :Johanna Spångberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Chemical fertilisers contribute to greenhouse gas emissions, fossil fuel use, use of non-renewable phosphate rock and a flow of reactive nitrogen to the biosphere, exceeding the planetary boundaries. Recycling of plant nutrients from waste and by-products from society would reduce the use of chemical fertilisers. LÄS MER

  3. 2. Modulation of the glycoalkaloid biosynthesis pathway in potato (Solanum tuberosum L.) and development of CRISPR/Cas9 methodology for tomato (Solanum lycopersicum L.)

    Författare :Ying Liu; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Steroidal glycoalkaloids (SGAs) are toxic defence substances present in Solanum species, including the tomato and potato. Concerns about SGA toxicity have long been raised regarding table potato cultivars, and more recently regarding starch potato cultivars, where SGAs negatively affect the use of proteins and fibre from starch by-products.

  4. 3. Valorization of herring filleting co-products to silage - Control of protein hydrolysis and lipid oxidation during ensilaging and possibilities for separating herring silage into multiple products

    Författare :Mursalin Sajib; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; separation; silage; pilot-scale; lipid oxidation; Herring Clupea harengus ; protein hydrolysis; ensilaging; antioxidants; fish oil; valorization; by-products;

    Sammanfattning : Industrial processing of herring ( Clupea harengus ) into convenience products such as fillets generates around 60% co-products being rich in both protein and n-3 polyunsaturated fatty acids (PUFAs). A promising cost-efficient strategy to valorize these raw materials into food and/or feed ingredients would be to apply ensilaging, i.e. LÄS MER

  5. 4. Cross-Processing Fish Co-Products with Plant Food Side Streams or Seaweeds Using the pH-Shift Method - a new sustainable route to functional food protein ingredients stable towards lipid oxidation

    Författare :Jingnan Zhang; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; valorization; pomaces; protein techno-functionality; press cakes; by-products; fish protein; fruit; natural antioxidants; lipid oxidation; berry; protein gels;

    Sammanfattning : The seafood value chain is highly inefficient as 50-60% of the fish weight end up as co-products in the filleting operation. Despite their abundance in high-quality proteins, fish co-products mainly go to low value products such as fodder. The pH-shift process, i.e. LÄS MER

  7. 5. Development of Methods for Analysis of Valuable Compounds in By-products from Agricultural and Forestry Industrial Sectors

    Författare :Mikael E Fridén; Per J R Sjöberg; Jonas Bergquist; Marja-Liisa Riekkola; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; industry by-products; flavonoids; triterpenes; mass spectrometry; Kemi med inriktning mot analytisk kemi; Chemistry with specialization in Analytical Chemistry;

    Sammanfattning : A growing interest in sustainable development has made efficient utilisation of starting materials and, if they occur, by-products become increasingly important. Vast amounts of by-products are generated by the forestry and food industry. LÄS MER
