  1. 1. Sensory quality of pork : Influences of rearing system, feed, genotype, and sex

    Author : Anette Jonsäll; Uppsala universitet; []
    Keywords : AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Domestic sciences; Sensory analysis; rearing system; genotype; sex; feed; pig; food quality; taste; muscle; Hushållsvetenskap; Domestic science and nutrition; Hushålls- och kostvetenskap;

    Abstract : Hampshire crosses of different genotype and sex were used to investigate the effects of rearing system, feed and handling on sensory quality, consumer preference and cooking loss. A selected and trained panel carried out descriptive tests. Two preference tests were carrieout by, in each case, 200 consumers. READ MORE

  2. 2. Towards a Better Understanding and Control of Factors Affecting the Physical Quality of Fish Feed

    Author : Julia Wolska; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fish Feed; Physical quality; Durability; Aging; Crosslinking; Transglutaminase;

    Abstract : As aquaculture expands, the volume of fish feed produced and transported must also increase. Therefore a better understanding and increased control of the factors that influence the physical quality of feed pellets is required. To achieve this goal, reliable methods measuring the physical quality of feed are needed. READ MORE

  3. 3. Impact of glucose feed rate on productivity and recombinant protein quality in Escherichia coli

    Author : Anna Maria Sandén; Gen Larsson; Gunnar Lidén; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Escherichia coli; recombinant protein production; fed-batch; feed profile; specific growth rate; Biokemi; Biochemistry; Biokemi;

    Abstract : The goal of this work was to contribute to the fed-batch process optimisation task by deriving parameters that have considerable impact on productivity as well as product quality The chosen parameters were I) the design of the glucose feed profile, II) the choice of induction strategy, with respect to the method of addition, and III) the time of the induction, with respect to the specific glucose consumption rate.The present fed-batch experiments using the lacUV5-promoter, for production of b-galactosidase, have shown that a high glucose feed rate gives a specific production rate, qp, that is twice as high, after induction, compared to a feed rate that is 2.

  4. 4. Multivariate Synergies in Pharmaceutical Roll Compaction : The quality influence of raw materials and process parameters by design of experiments

    Author : Nabil Souihi; Johan Trygg; Jukka Rantanen; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; MEDICAL AND HEALTH SCIENCES; Roll compaction; dry granulation; mannitol; dicalcium phosphate; design of experiments; orthogonal projections to latent structures; critical quality attributes; tablet manufacturing; quality by design; design space; near-infrared chemical imaging; texture analysis; modeling; scale up; instrumented roll; Johanson model;

    Abstract : Roll compaction is a continuous process commonly used in the pharmaceutical industry for dry granulation of moisture and heat sensitive powder blends. It is intended to increase bulk density and improve flowability. READ MORE

  5. 5. Methodology for high-throughput production of soluble recombinant proteins in Escherichia coli

    Author : Katrin Markland; Gen Larsson; Pär Nordlund; Jenny Ottosson; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Escherichia coli; high-throughput methodology; recombinant protein production; solubility; productivity; quality; cultivation technology; parallel reactors; Biochemistry; Biokemi;

    Abstract : The aim of this work was to investigate and determine central parameters that can be used to control and increase the solubility, quality and productivity of recombinant proteins. These central parameters should be applicable under the constraints of high-throughput protein production in Escherichia coli. READ MORE
