  2. 1. Structuring plant cell materials using pre-treatments. Effects on texture and carotenoid accessibility

    Author : Evelina Tibäck; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PG; degree of methoxylation; texture; carrot; Bostwick consistency index; microstructure; in vitro carotenoid accessibility; PME; tomato; carotenoid content;

    Abstract : A high consumption of fruits and vegetables is considered beneficial and to support good health. To promote higher fruit and vegetable intake, attractive and nutritious fruit- and vegetable-based ready-to-eat products should be available on the market. A key property of an attractive food product is a palatable texture. READ MORE

  4. 2. Dissecting the photosystem II light-harvesting antenna

    Author : Jenny Andersson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; antisense; Arabidopsis thaliana; chlorophyll; carotenoid; feedback de-excitation; fitness; LHC; NPQ; photosynthesis; state transitions; xanthophyll; Växtfysiologi; Plant physiology; Växtfysiologi; Physiological Botany; fysiologisk botanik;

    Abstract : In photosynthesis, sunlight is converted into chemical energy that is stored mainly as carbohydrates and supplies basically all life on Earth with energy.In order to efficiently absorb the light energy, plants have developed the outer light harvesting antenna, which is composed of ten different protein subunits (LHC) that bind chlorophyll a and b as well as different carotenoids.

  5. 3. The photophysics and functions of some naturally occurring carotenoids

    Author : Helena Billsten; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi; xanthophyll-binding proteins; vibrational relaxation; light-harvesting complexes; carotenoid aggregates; carotenoids; excited states; femtosecond pump-probe spectroscopy; xanthophylls;

    Abstract : Carotenoids are one of the most widespread and important group of pigments in Nature and they can act as light-harvesting agents, photoprotectors and antioxidants. Mechanisms of their multiple functions are not fully understood mainly because their complicated photophysics involving ?dark? excited states. READ MORE

  6. 4. Violaxanthin de-epoxidase and its closest relative: identification and characterization

    Author : Kuo Guo; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Photosynthesis; Carotenoid conversions; violaxanthin de-epoxidase VDE ; Violaxanthin de-epoxidase related protein;

    Abstract : Light is essential for plants and algae to process photosynthesis. However, excess of light will cause damage to the organism. A process called non-photochemical quenching (NPQ) is an important way for these organisms to protect themselves from photo oxidative damage. READ MORE

  7. 5. Development and maintenance of quality indicators in pheasants

    Author : Thomas Ohlsson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PHA; ELISA; immunocompetence; carotenoid coloration; male ornaments; fluctuating asymmetry; growth; early development; Phasianus colchicus; egg size; sexual selection; Animal ecology; Djurekologi; Ecology; Ekologi;

    Abstract : Females often base their choice of mates on the expression, size or intensity, of male sexual ornaments. Indicator models of sexual selection assume that females assess male genetic quality through the expression of these secondary sexual characters. READ MORE
