  1. 1. Valorisation of cereal by-products: a biorefinery approach

    Författare :Reskandi C. Rudjito; Franscisco Vilaplana; Amparo Jimenez-Quero; Mirjam Kabel; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cereal by-products; arabinoxylan; ferulic acid; subcritical water extraction; enzymatic treatment; xylanases; prebiotics; Jordbruksbiprodukter; arabinoxylan; ferulsyra; subkritisk vattenextraktion; enzymatisk behandling; xylanaser; prebiotika; Bioteknologi; Biotechnology;

    Sammanfattning : Cereal by-products are abundant streams of underutilised biomass that have the potential be valorised into various industrial products by means of environmentally friendly processes. In this study, an integrated bioprocess combining subcritical water extraction (SWE) and enzymatic treatment (ET) was proposed to effectively extract arabinoxylans (AX) from cereal by-products.

  3. 2. Fermentation as a Means of Optimizing the Glycaemic Index - Food Mechanisms and Metabolic Merits with Emphasis on Lactic Acid in Cereal Products

    Författare :Elin Östman; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nutrition; starch; healthy human; fermentation; lactic acid; sourdough; cereal products; milk; glycaemic index; bread; Näringslära; diabetes; insulin response;

    Sammanfattning : In current recommendations from FAO/WHO, foods that elicit low glycaemic responses and thus have low glycaemic indices (GIs) are advocated. The rationale for this recommendation is that low-GI diets have been shown to reduce risk factors for e.g. type II diabetes and cardiovascular disease. LÄS MER

  4. 3. Multifunctional carbohydrate-based soft materials from cereal by-products

    Författare :Secil Yilmaz Turan; Francisco Vilaplana; Rosana Moriana; Amparo Jiménez Quero; Anna Ström; KTH; []
    Nyckelord :wheat bran; corn bran; hemicellulose; arabinoxylan; ferulic acid; subcritical water extraction; acetylation; films; hydrogels; crosslinking; regeneration; antioxidant activity; vetekli; majskli; hemicellulosa; arabinoxylan; ferulsyra; subkritisk vattenextraktion; acetylering; filmer; hydrogeler; tvärbindning; regeneration; antioxidant aktivitet; Bioteknologi; Biotechnology;

    Sammanfattning : Cereal production generates large quantities of by-products every year, which still remain underutilized. The hemicellulose fractions from cereal by-products are anticipated to play an important role in tomorrow's sustainable and bio-based circular economy. LÄS MER

  5. 4. Hydrolysis of by-products from cereal kernels for improved ethanol production

    Författare :Beatriz Palmarola Adrados; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; starch-free fibres; Kemiteknik och kemisk teknologi; wheat starch fibres; starch-free bran; wheat bran; SSF; enzymatic hydrolysis; H2SO4; microwave pretreatment; Ethanol production; steam pretreatment;

    Sammanfattning : This work deals with the hydrolysis of lignocellulosic agricultural residues, by means of combined pretreatment and enzymatic hydrolysis, to be used for ethanol production. Four agricultural by-products, i.e. LÄS MER

  7. 5. Characterisation of dietary fibre in cereal grains and products : emphasis on triticale and rye

    Författare :Allah Rakha; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Utility of cereals is mainly defined by their composition. High content of extractable dietary fibre (DF) with retained molecular features may be desired for human consumption to derive certain benefits associated with DF. LÄS MER
