Gelation of triple helical (1→ 3)-β- D -glucan: The scleroglucan case
(Dr. ingeniøravhandling, 0809-103X; 2003:90, Doctoral thesis, 2003)The topic of this thesis has been gelation of the triple helical (1→3)- β glucan, scleroglucan. Two basically different methods of scleroglucan gelation were studied. Gels were made by altering the primary structure of ... -
Fish Gelatin from Cold Water Fish Species: Physical and rheological characterisation of fish gelatin and mixtures of fish gelatin and kappa-carrageenan
(Dr. ingeniøravhandling, 0809-103X; 2003:24, Doctoral thesis, 2003)This study comprises physical and rheological characterisation of fish gelatin (FG) from cold water fish species, and the mixtures of fish gelatin and kappa-carrageenan (CG). The low content of proline and hydroxyproline ... -
Endogenous proteolytic enzymes - Studies of their impact on fish muscle proteins and texture
(Dr. ingeniøravhandling, 0809-103X; 2003:110, Doctoral thesis, 2004)This thesis covers studies on endogenous proteolytic enzymes and their impact on fish muscle proteins and texture. The studies have been performed using Atlantic salmon (Salmo salar) and cod (Gadus morhua) subjected to ... -
