    Author : Mauricio Penarrieta; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bolivia; Foods; Flavonoids; Phenolic Compounds; Total Antioxidant Capacity; HPLC.;

    Abstract : The total antioxidant capacity was measured and the major phenolic and flavonoid compounds were identified and quantified in a selection of Bolivian crops growing at different altitudes above seal level (a.s.l.). READ MORE

  4. 2. Enzymatic hydrolysis coupled to hot water extraction for determination of flavonoids in plants

    Author : Sofia Lindahl; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; extraction; flavonoids; quercetin; biocatalysis; beta-glucosidase; sustainable chemistry; hyphenation; molecularly imprinted polymers; onion;

    Abstract : The word sustainability is more and more frequently used within the field of chemistry and in many other fields. Green or sustainable chemistry was introduced during the 90 ́s as a field of chemistry where the environmental and health impacts of processes and products are evaluated and improved. READ MORE

  5. 3. Polyphenols in Swedish berries and pulses : Characterization and in vivo effects of fractions from lingonberries and brown beans in an Apoe-/- mouse model

    Author : Jiyun Liu; Cornelia Witthöft; Anne-Maria Pajari; Linnéuniversitetet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; lingonberry; brown bean; flavonoids; phenolic acids; dietary fiber; HPLC-UV MS; atherosclerotic plaque; plasma lipid; gut microbiota; short-chain fatty acids; trimethylamine N-oxide; Apoe- - mice; lingon; bruna bönor; flavonoider; fenolsyror; kostfiber; HPLCUV MS; aterosklerotisk plaketter; plasmalipid; tarm-mikrobiota; kortkedjiga fettsyror; trimetylamin N-oxid; Apoe- - möss; Livsmedelsvetenskap; Food Science;

    Abstract : Consumption of berries and pulses can protect against atherosclerosis and other metabolic diseases, by modulating plasma lipid profile, gut microbiota, and microbiota-dependent metabolites. These nutritional benefits are often attributed to high content of polyphenols (flavonoids and phenolic acids) and dietary fiber. READ MORE

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