  1. 1. Cereal husbandry and settlement : Expanding archaeobotanical perspectives on the southern Scandinavian Iron Age

    Författare :Radoslaw Grabowski; Karin Viklund; Hans Peter Stika; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; cereal cultivation; iron age; southern Scandinavia; archaeobotany; settlement archaeology; environmental archaeology; miljöarkeologi; Archaeology; arkeologi;

    Sammanfattning : The here presented PhD project explores the phenomenon of cereal cultivation during the Iron Age (c. 500 BC – AD 1100) in southern Scandinavia. The main body of the thesis consists of four articles. LÄS MER

  3. 2. Absorption and accumulation of cadmium from cereal grains

    Författare :Anncatherine Moberg Wing; Umeå universitet; []
    Nyckelord :cadmium accumulation; cereal grains; dietary fiber; iron status; pregnancy;

    Sammanfattning : Cadmium (Cd) is a potentially toxic trace element. Cereal grains contribute one-third to one-half of the Cd exposure via the diet. Among cereal grains, wheat generally contains the highest Cd concentration and the bran and germ fractions contain more Cd than the endosperm. LÄS MER

  4. 3. Material Properties of Starch and Cereal Protein Films and Foams

    Författare :Thomas Gillgren; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; foam; avenin; oxygen permeability; amylopectin; water vapour permeability; plasticization; mechanical properties; zein; film; glass transition temperature; kafirin; prolamin; cereal protein; amylose; starch;

    Sammanfattning : Materials that are renewable and biodegradable are demanded for environmental reasons. Biopolymeric materials, such as materials from starch and cereal proteins, are both renewable and biodegradable. However, starch and cereal protein materials are generally rather brittle and therefore need to be plasticized to become more flexible. LÄS MER

  5. 4. 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.

  7. 5. Material Properties of Cereal Protein Films

    Författare :Thomas Gillgren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plasticization; avenin; prolamin; kafirin; mechanical properties; water vapour permeability; oxygen permeability; protein; film; glass transition temperature; zein;

    Sammanfattning : Materials that are renewable and biodegradable are demanded due to environmental aspects. Biopolymeric materials, such as materials from prolamins, fulfil both of these requirements. Prolamins are cereal storage proteins. Examples of such are zein, gluten, kafirin and avenin from maize, wheat, sorghum and oats, respectively. LÄS MER
