  1. 1. Carrot Juice Processing - Effects on Various Quality Aspects

    Författare :Charlotte Alklint; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modified atmosphere; shelf-life; accelerated storage; isothermal calorimetry; pressing; expression method; colour; dietary fibre; carotene; composition; carrot pomace; carrot juice; carrot pulp; acidification; Food and drink technology; Livsmedelsteknik;

    Sammanfattning : Carrots are a cold-weather crop well suited for cultivation in the south of Sweden. Carrots are generally rather inexpensive, with a market price below € 1 /kg (Sweden, 2003), whereas fresh carrot juice has a price of around € 5 /kg. LÄS MER

  3. 2. Lactobacillus in semi-hard cheese and their use as adjunct cultures

    Författare :Martin Antonsson; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; Adjunct culture; NSLAB; Non-starter Lactic acid bacteria; Cheese ripening; Model cheese; Lactobacillus paracasei; Cheese; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : The microflora of Herrgård cheese produced at three dairies was compared after three and six months maturation. The microflora of cheeses from two of the dairies was dominated by a spontaneous microflora of Lactobacillus after three months of ripening, while starter bacteria still dominated in cheese from the third dairy after six months.

  4. 3. Lipid bilayers versus monolayers- Sponge phases and skin lipid domains

    Författare :Katarina Ekelund; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fatty acids; Langmuir-Blodgett films; AFM; domains; stratum corneum; bilayer curvature; lipids; glycerol monooleate; phase behaviour; sponge phase; L3 phase; Livsmedelsteknik; cholesterol; Food and drink technology;

    Sammanfattning : The L3, or sponge, phase is a thermodynamically stable isotropic liquid consisting of a surfactant membrane in aqueous solution. A solvent induced L3 phase is shown in systems of solvent, monoolein and water. LÄS MER

  5. 4. Bacteriological Hygiene in the Production of Pasteurised Milk

    Författare :Åsa Eneroth; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; RAPD; Bacillus cereus; Pseudomonas; Gram-negative; recontamination source; spoilage flora; phychrotrophs; recontamination; dairy hygiene; pasteurised milk; Livsmedelsteknik;

    Sammanfattning : Critical contamination sites and sources for the Gram-negative psychrotrophs (GNP) of the taxa Pseudomonas, Enterobacteriaceae and Aeromonas, and the Gram-positive spore-forming (GPS) species Bacillus cereus, have been traced in the production line of pasteurised milk. Samples of raw and pasteurised milk from different sampling sites along the line were collected. LÄS MER

  7. 5. Pulsed Electric Field Treatment of Plant Tissue

    Författare :Mustafa Fincan; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bimodal Fickian diffusion model; Food and drink technology; Livsmedelsteknik; generalized Maxwell model; onion Neutral Red; visualization; red beetroot; potato; epidermis; plant tissue; electroporation; Cell permeabilization; Pulsed electric field; PEF;

    Sammanfattning : A pulsed electric field (PEF) is a newly emerged non-thermal food processing technology which has characteristic effects on the cell membrane. PEF processing involves subjecting food to short, repeated pulses of a high electric field between an anode and a cathode. LÄS MER
