2. 16. Quality Aspects of Modified Atmosphere Packaged Broccoli

   Author : Annelie Jacobsson; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; heat transfer; mass transport; quality; flavour; aroma; modified atmosphere packaging; broccoli;

   Abstract : The modified atmosphere packaging (MAP) of vegetables is used with the aim of prolonging the shelf-life of the packaged produce. The packaging material consists of a permeable film and as a result of the respiration of the produce and gas diffusion through the film, the O2 decreases and the CO2 increases inside the package.

4. 17. Factors Controlling Meat Quality of Pork in Relation to Breed and RN Genotype

   Author : Åsa Josell; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Livsmedelsteknik; NIR; rigor development; tenderness; RN gene; Meat quality; pork;

   Abstract : The Hampshire breed was introduced as the terminal sire in Swedish slaughter pigs in the 1970s, mainly to reduce stress susceptibility and associated problems of meat quality, such as the meat being pale, soft and exudative (PSE). Since then, however, the RN – allele, a mutation which is only found in pure-bred Hampshire and in crosses with it, has been discovered. READ MORE

5. 18. Fouling and cleaning of solid surfaces. The influence of surface characteristics and operating conditions

   Author : Camilla Karlsson; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; ellipsometry; sodium hydroxide; anionic surfactant; betalactoglobulin; protein; stainless steel; hydrophilic surface; hydrophobic surface; cleaning; adsorption; fouling; Livsmedelsteknik; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

   Abstract : The severe fouling common in food processing puts high demands on equipment cleaning. Adsorption of the protein betalactoglobulin to solid surfaces and its subsequent removal were followed using in situ ellipsometry. Most experiments were done in a stirred cuvette. Additionally, a flow cell was designed, which was employed in some work. READ MORE

6. 19. Flow and turbulence in the discharge stream of different agitators for stirred tanks

   Author : Tamás Kovács; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluiddynamik; Gaser; plasmas; fluid dynamics; Gases; Livsmedelsteknik; Food and drink technology; Scaba; 6SRGT; pseudo turbulence; Rushton; stirred tank; plasma; Mechanical engineering; hydraulics; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

   Abstract : In this thesis, the fluid dynamic properties of the conventional Rushton turbine and another impeller type, the Scaba Radial flow Gas dispersing Turbine (with six concave blades) are compared. For comparison, point-wise velocity measurements were made in the discharge of the two turbine types using Hot-Wire Anemometry in constant temperature mode (CTA) with a split film probe. READ MORE

7. 20. The mechanisms controlling heat and mass transfer on frying of beefburgers

   Author : Bea Kovácsné Oroszvári; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; permeability; porosity; contraction; frying; beefburger; heat and mass transfer;

   Abstract : The aim of the present work was to gain better understanding of the mechanisms controlling heat and mass transfer during thermal processing of beefburgers. The effects of different factors such as the chemical composition and comminution of the meat raw material, the pan temperature and the meat patty diameter on the characteristics of heat and mass transfer were studied.
