  2. 1. Aroma Partition and Release from Soft Drinks, Jam, and Jellied Sweets

    Author : Annika Hansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gas chromatography; aroma; gel; model mouth; partition coefficient; release; citric acid; pectin; in-nose; sugar; proton-transfer reaction mass spectrometry; soft drink;

    Abstract : The research described in the present thesis was focused on the influence of food ingredients and structures on the partition and release of aroma compounds from model systems such as soft drinks, jam, and jellied sweets. The effects on aroma release were studied during both static and dynamic conditions, the latter by both model mouth and in-nose measurements. READ MORE

  4. 2. Optimisation and modelling of aroma recovery by pervaporation

    Author : Jenny Olsson; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; optimisation; mass transfer; modelling; pervaporation; aroma recovery; Livsmedelsteknik;

    Abstract : During production of concentrated fruit juices, both physical and chemical losses of aroma compounds occur due to heat treatment such as pasteurisation and evaporation. This leads to an inferior quality of the final product. READ MORE

  5. 3. 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.

  6. 4. Reuse and Recycling of Food Packaging - Odour Related Aspects of the Use and Misuse of PET Beverage Bottles

    Author : Heléne Widén; Avdelningen för livsmedel och läkemedel; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Livsmedelsteknik; Food and drink technology; aroma transfer; reuse; recycling; migration; contaminants; post consumer material; food packaging; polyethylene terephthalate PET ;

    Abstract : The reuse and closed-loop recycling of food packaging was studied in order to assess consumer safety and the sensory quality (e.g. taste and smell) of packaged food. READ MORE

  7. 5. An Analytical Solution Applied to Heat and Mass Transfer in a Vibrated Fluidised Bed Dryer

    Author : Apolinar Picado; Joaquín Martínez; Göran Lindbergh; Ivars Neretnieks; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Analytical solution; Heat and mass transfer; Temperature and moisture distribution; Drying modelling; Multicomponent drying; Drying selectivity; Volatile retention; Ternary mixture; Drying of particulate materials; Vibrated fluidised bed dryer; Chemical engineering; Kemiteknik;

    Abstract : A mathematical model for the drying of particulate solids in a continuous vibrated fluidised bed dryer was developed and applied to the drying of grain wetted with a single liquid and porous particles containing multicomponent liquid mixtures. Simple equipment and material models were applied to describe the process. READ MORE
