    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; antioxidants; invertase; thawing; blackcurrant; strawberry; fruit; berry; Livsmedelsteknik;

    Abstract : The industrial production of preserves includes several unit operations which all affects sensorial properties as well as the nutritional value of the final product. Thawing is a crucial unit operation, since then both chemical and physical changes take place. READ MORE

  5. 8. Recycling of nickel metal hydride (NiMH) batteries; Characterization and recovery of nickel, AB5 alloy and cobalt

    Author : Filip Holmberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; recycling; nickel; AB5 alloy; cobalt; NiMH battery; hydrogen storage alloy; leaching;

    Abstract : Nickel metal hydride (NiMH) batteries are used today for applications that can assist in the adaptation toward carbon-neutral energy sources (i.e. hybrid vehicles and smart grids). Recovery of metals such as nickel, cobalt and rare earth elements (REEs) from discarded NiMH batteries is important for economic and/or technological reasons. READ MORE

  6. 9. Antioxidant Capacity in Fruit and Vegetables -Cultivar Variation - Storage Conditions - Human Antioxidant Status

    Author : Jessica Nilsson; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; human plasma antioxidants; Brassica; strawberry; pea; cultivar; ABTS; FRAP; Total antioxidant capacity; TAC; Food and drink technology; Livsmedelsteknik;

    Abstract : The health-promoting effects of fruits and vegetables have been extensively discussed during the past decade since epidemiologic studies have shown relations between increased intake of fruit and vegetables and decreased incidences of several chronic diseases. It has been suggested that antioxidants are a main contributors to the observed effects, for example by acting as scavengers of free radicals. READ MORE

  7. 10. Fungi-Based Biorefinery : Valorization of industrial residuals and techno-economic evaluation

    Author : Gülru Bulkan; Mohammad J Taherzadeh; Mats Galbe; Högskolan i Borås; []
