  2. 1. Interactions between polyphenols and macromolecules facilitate the extraction of low viscosity banana juice

    Author : Nuria Majaliwa; Chalmers tekniska högskola; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; response surface methodology; polyphenols; banana juice; East African Highland bananas; Fourier Transform Infrared spectroscopy; protein distributions;

    Abstract : Bananas are an important staple food and cash crop throughout the African Great Lakes region where they contribute highly to livelihood and food security. However, bananas are perishable fruits that require effective processing techniques to reduce post-harvest losses. READ MORE

  4. 2. Aroma characterisation and retention after heat treatment and drying of fruits using extraction and GC-MS analysis

    Author : Rui Ráice; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fruits; Vangueria infausta; Mangifera indica; volatile; aroma; blanching; drying; encapsulation; modelling; GC-MS.;

    Abstract : This study concerns the identification and characterisation of volatile components of fruits, and evaluation of the effect of heat treatment and drying on retention or loss of volatiles of fruits. The investigation included developing a procedure to extract volatile components from the fruit matrix, a purification step, separation, identification and quantification. READ MORE

  5. 3. Toxoplasma gondii in wild boars and domestic pigs in Sweden : implications for food safety

    Author : Camilla Gustafsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Ingestion of undercooked meat is a major risk factor for human toxoplasmosis, a disease caused by the zoonotic protozoan parasite Toxoplasma gondii. Infected pork, mutton and game meat are considered important infection sources in Europe. This thesis aims to describe the epidemiology of T. READ MORE

  6. 4. Microbial Production of Bio-Based Chemicals: A Biorefinery Perspective

    Author : Tarek Dishisha; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biorefinery; platform chemical; organic acid; propionic acid; 3-hydroxypropionic acid; 3-hydroxypropionaldehyde; methacrylic acid; 1; 3-propanediol; Propionibacterium acidipropionici; Lactobacillus reuteri; Gluconobacter oxydans; high cell density fermentation; biotransformation; product inhibition; cell recycle; immobilized cells; chemical catalysis; pdu operon;

    Abstract : A shift from fossil- to renewable biomass feedstock for the emerging bio-based economy requires the development and adoption of new sustainable technologies that are more suited for transformation of biomass components to chemicals, materials and energy. This thesis presents investigations on the development of processes based on industrial biotechnology as a key element for the production of chemicals from agro-/industrial by-products. READ MORE

  7. 5. Characterization of a Voltammetric Electronic Tongue

    Author : John Olsson; Fredrik Winquis; Tautgirdas Ruzgas; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Electronic tongues were developed some ten years ago. These systems consist of an array of nonspecific sensors and a signal processing unit. The sensor signals are processed by pattern recognition methods which makes possible the extraction of specific properties from the sample. READ MORE
