  2. 1. COMBINED DEHYDRATION METHODS - From Fresh Fruit to High-quality Ingredients

    Author : Frédéric Prothon; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Livsmedelsteknik; semi-finished products; agent; collapse; apple; microwave-assisted air-drying; dehydration; osmotic treatment;

    Abstract : Numerous products from the food industry contain fruit and/or berries, in the form of fillings or ingredients, e. g. in yoghurt, some bread products/cereal products, ice cream, etc. In order to produce these ingredients and improve their characteristics, many processing techniques are available.

  4. 2. 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

  5. 3. Effects of Dehydration and Blockade of the Renin-Angiotensin System in the One-humped Camel (Camelus dromedarius)

    Author : Mahmoud Al Haj; Fred Nyberg; Santi Spampinato; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood; biochemical analysis; catecholamine; colorimetric assay; cortisol; dehydration; dromedary camel; glutathione; hematological analysis; HPLC; insulin- like growth factor-1; losartan; plasma; receptors; radioimmunoassay; serum; Pharmaceutical Science; Farmaceutisk vetenskap;

    Abstract : The one-humped or the dromedarian camel is a pseudo-ruminant mammal, well adapted to the hot and dry climates of the desert. Its ability to withstand torrid heat and extreme desiccation is of paramount importance to its survival. READ MORE

  6. 4. Molasses Purification and Valorisation : Towards a sustainable production of hydroxymethylfurfural

    Author : Mikael Sjölin; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sugar beet molasses; 5-hydroxymethylfurfural; membrane filtration; hydrolysis; dehydration; adsorption; purification; solvent regeneration;

    Abstract : The industrial transition from petrochemical-based to a more sustainable and circular economy requires the utilisation of renewable biobased raw materials that do not compete with other important industries, such as the food sector, preferably wastes or low value by-products. 5-hydroxymethylfurfural (HMF) is a versatile platform chemical that has great potential for utilisation in various sectors in a future bioeconomy, as it can be produced from sugars.

  7. 5. Heat exposure and health outcomes in Costa Rican sugarcane harvesters

    Author : Jennifer Crowe; Maria Nilsson; Tord Kjellström; Catharina Wesseling; Linda Forst; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Agricultural worker; Central America; Chronic kidney disease; Climate change; Dehydration; Heat; Heat illness; Heat stress; Sugarcane; Urinalysis; Worker health; folkhälsa; Public health; Epidemiology; epidemiologi;

    Abstract : Background The remarkably efficient mechanisms of the human body to maintain its core temperature of 37°C can be inadequate when harsh climatic conditions and excessive muscle movement lead to heat stress, dehydration and potential heat illness, ranging from minor symptoms such as fatigue to a potentially fatal heat stroke. Agricultural workers in the tropics are at high risk, which is expected to increase with climate change. READ MORE
