  1. 1. Flow processing and gel formation for producing biopolymer drops with functional shapes and diffusion properties

    Författare :Bernhard Walther; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; drop deformation; 4-roll mill; biopolymer; agarose; shear; Kappa-carrageenan; elongation; microstructure; flow processing; drop-shaping; rheology; poly ethyleneglycol ; diffusion; gelatine; NMR; gel formation; TEM; flow channel;

    Sammanfattning : This thesis focuses on the development of novel processes which combine flow-induced drop deformation and simultaneous temperature-induced gel formation in order to create shaped biopolymer drops. The drops are functional in terms of rheology and diffusion properties, factors strongly influencing the consistency of food products and flavour or drug release. LÄS MER

  3. 2. Phase separation, aggregation and gelation of a charged helixforming polysaccharide in aqueous salt solution

    Författare :Johan Borgström; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; polysaccharide; physical gel; ion binding; carrageenan; liquid crystal; polymer; Fysikalisk kemi;

    Sammanfattning : The phase behaviour and gelation of the anionic polysaccharide kappa-carrageenan (KC) in different salt solutions was studied. The specific site binding of certain anions and certain cations to the KC helix was used as a means of controlling the interactions. LÄS MER

  4. 3. Rheology and Microstructure of Mixed Biopolymer Gels

    Författare :Leif Lundin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carrageenan; microstructure; rheology; xanthan; PCA; polysaccharide mixture; locust bean gum; transmission electron microscopy TEM ; multivariate analysis; viscoelastic measurements; PLS;

    Sammanfattning : The viscoelastic behaviour of biopolymer mixtures showing synergism was investigated under different physicochemical conditions using small deformation oscillatory measurements. In addition, the rheological properties of binary polysaccharide mixtures were related to the microstructure as observed using transmission electron microscopy. LÄS MER
