  1. 6. Microbial test organisms for sterilization processes in food industry

    University essay from Lunds universitet/Bioteknik; Lunds universitet/Teknisk mikrobiologi

    Author : Yasmin Nabila; [2018]
    Keywords : Aseptic processing and packaging; validation; test organisms; Aspergillus brasiliensis; Bacillus atrophaeus; Bacillus subtilis; sterilization; disinfection; applied microbiology; teknisk mikrobiologi; Technology and Engineering; Agriculture and Food Sciences;

    Abstract : The importance of sterilization processes has been a major topic in the food manufacturing industry since it preserves the quality and provides longer shelf-life by preventing microbiological recontamination of products. Aseptic packaging is an alternative technique to pack commercially sterile products into containers with a very low recontamination rate, thus, the entire production chain must be designed according to the aseptic condition, including the packaging material, the filling machines, and the surrounding area where the process takes place.

  3. 7. Fouling Dependency of Air in Dairy Processing

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Erik Lorin; [2018]
    Keywords : Fouling; Dairy; UHT; Bubble; Bubble induced fouling; Drying; THE; Dairy Processing; Processing; Bubble Nucleation; Differential Pressure; Oxygen sensors; chemical engineering; kemiteknik; Agriculture and Food Sciences; Chemistry; Technology and Engineering;

    Abstract : In this master thesis project, the formation of fouling on heat exchanger surfaces in dairy processing and mainly the influence of air was examined. Based on prior experimental findings regarding the influence of air bubbles in combination with calculations based on solubility properties of air in milk, a hypothesis was stated. READ MORE

  4. 8. Proteinsammansättning i mjölk med lång hållbarhet (UHT-behandlad mjölk)

    University essay from SLU/Dept. of Food Science

    Author : Johanna Frick; [2016]
    Keywords : UHT-mjölk; kapillärelektrofores; mjölkprotein; proteinprofil; lagringstid; lagringstemperatur;

    Abstract : I den här rapporten har lagring av mjölk med lång hållbarhet analyserats för att ta reda på om det sker proteinnedbrytning under lagring och om nedbrytningen är beroende av lagringstid, lagringstemperatur (4, 20, 30 respektive 37°C), eller en kombination av dessa parametrar. Den analyserade mjölken producerades i november 2014 och lagrades ett år. READ MORE

  5. 9. Seasonal variations in plasmin activity in Swedish silo and UHT milk

    University essay from SLU/Dept. of Food Science

    Author : Eva Edlund Tjernberg; [2016]
    Keywords : plasmin; plasminogen; UHT; bovine milk; seasonal variation;

    Abstract : Plasmin (PL) is a native proteinase in milk, which incorporates a complex system of inhibitors and activators, whose activity is known to cause changes in ultra-high temperature (UHT) treated milk during storage. The objective of this study was to investigate if there were any seasonal variations in PL and plasminogen (PG) de-rived PL activity in Swedish silo and UHT milk, and if enzyme activity was affect-ed by storage temperature and storage time.

  6. 10. Mejeriprocessernas påverkan på mjölkens komponenter

    University essay from SLU/Dept. of Food Science

    Author : Agatha Sapieja; [2015]
    Keywords : homogenisering; pastörisering; mjölkens beståndsdelar komponenter; MFGM; laktos; kasein; vassle; UHT;

    Abstract : Mjölk och mejeriprocesser är ett omdiskuterat ämne. Det dyker regelbundet upp nya studier inom området och meningarna är delade om mejeriprocesser och deras påverkan på mjölkens beståndsdelar. READ MORE
