  2. 1. Microwave-Assisted Air-Dehydration of Fruits and Vegetables Processing Conditions and Product Quality

    Author : Tomas Funebo; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dielectric properties; pre-treatment; dehydration; permittivity; microwave; fruits; vegetables; multimode;

    Abstract : This thesis is focused on aspects of microwave-assisted hot-air drying of fruits and vegetables. The two material coefficients, the relative permittivity (ε) and the loss factor (ε), determine the interaction of microwave energy with foods. 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. Preharvest Conditions Affecting Apple Quality, Antioxidant Responses and Susceptibility to the Infection by Grey mould (Botrytis cinerea)

    Author : Tuyet Bui Thi Anh; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Malus x domestica; grey mould; preharvest weather; apples’ quality; antioxidants; harvest year;

    Abstract : Apple fruits are rich in vitamin C and other antioxidants, which are beneficial for human health. During postharvest storage, there are losses as a result of diseases such as grey mould, caused by the fungus Botrytis cinerea. The present work has investigated how to obtain a high quality of apples, allowing long-term storage. READ MORE

  6. 4. Genetic variation in resistance to fungal storage diseases in apple : inoculation-based screening, transcriptomics and biochemistry

    Abstract : Apple is one of the economically and culturally most important fruit crops and has many health-related benefits. Apple production is, however, sensitive to several fungal diseases including blue mold, caused by Penicillium expansum. READ MORE

  7. 5. Utilization of Wild Fruit in Mozambique – Drying of Vangueria infausta (African medlar)

    Author : Eulália Chiau; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vangueria infausta; drying; maltodextrin; sucrose; softener; toughness; solar-assisted pervaporation; aroma; crystallization; water activity;

    Abstract : Vangueria infausta (African medlar) is a wild fruit found in southern and central Mozambique. The ripe fruit has a leathery skin enclosing three to five seeds embedded in a soft pulp that tastes like apple. It plays an important role in the diet of the rural population and has the potential for commercial use. READ MORE
