  1. 1. Contributions to the Use of Statistical Methods for Improving Continuous Production

    Författare :Francesca Capaci; Erik Vanhatalo; Bjarne Bergquist; Murat Kulahci; Johan Carlson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process industry; Continuous process; Statistical process control; Design of experiments; Process improvements; Simulation tool; Engineering process control; Kvalitetsteknik; Quality Technology Management;

    Sammanfattning : Complexity of production processes, high computing capabilities, and massive datasets characterize today’s manufacturing environments, such as those of continuous andbatch production industries. Continuous production has spread gradually acrossdifferent industries, covering a significant part of today’s production. LÄS MER

  3. 2. Food in the Future : energy and transport in the food system

    Författare :Christine Wallgren; Lars Orrskog; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food technology; Livsmedelsteknik;

    Sammanfattning : This thesis explores possible future forms of a sustainable food supply system from an energy aspect. Particular attention is devoted to local food supply as a means to reduce energy use for transport. The thesis consists of a covering essay and three studies: one futures study of the entire food supply system and two case studies of local farming. LÄS MER

  4. 3. Engagement with Fungi-Based Food : Recovery and Valorization of Resources for Food

    Författare :Coralie Hellwig; Kamran Rousta; Marianne Thomsen; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sustainable lifestyles; fungi; resource recovery; sustainable food; food waste reduction; Resource Recovery; Resursåtervinning;

    Sammanfattning : There has been an increasing demand for more sustainable food and ways of encouraging individuals to lead more sustainable lives. This thesis seeks to contribute to understanding human engagement with fungi-based food in a multidisciplinary manner by complementing resource recovery with an occupational perspective that sheds light on aspects that encourage or discourage individuals from engaging with this food.

  5. 4. Dynamic Modelling and Simulation of Liquid Food Process Lines

    Författare :Tomas Skoglund; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process lines; Dynamic model; Microbial deactivation; Data- och systemvetenskap; computer technology; Systems engineering; Fuzzy traceability; Traceability; Thermal engineering; termodynamik; Termisk teknik; applied thermodynamics; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Food and drink technology; Heat exchanger; Dispersion; Fluid property transition; Liquid food; Dynamic simulation; Livsmedelsteknik;

    Sammanfattning : In the present work a dynamic model library of components for process lines was developed. The analysis addressed characteristic aspects of liquid food process lines, and new models were developed for fluid transitions, dispersion, mixing zones and first-order chemical reactions in pipes and heat exchangers.

  7. 5. Characterisation of Food Associated Bacteria by DNA based Methods, with Special Reference to Enterobacteriaceae

    Författare :Crister Olsson; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; 16S rRNA; TTGE; ribotyping; Rahnella; Klebsiella; HPI; Enterobacteriaceae; food; Livsmedelsteknik;

    Sammanfattning : The presence of genes in food, encoding some virulence factors, was studied by PCR, and species of Enterobacteriaceae, associated with food, were studied by the DNA-based methods of TTGE, ribotyping and sequencing. The flora of fresh and chill-stored pork were analysed by a culture-independent approach, using specific amplification of 16S rRNA genes followed by cloning and sequencing. LÄS MER
