    Sammanfattning : Coffee is one of the most consumed beverages in the world, with about 10 million tons of coffee consumed in 2021. There are a lot of steps between the coffee tree and served beverage, as there are several processing methods each contributing to differences in fragrance, aroma, and acidity. LÄS MER

  4. 3. Improvement of Pt-based catalyst supported on CeZrO2 used for the high-temperature water-gas shift reaction

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Milda Grikainyte; [2022]
    Nyckelord :Water-gas shift; catalyst; chemical engineering; Chemistry;

    Sammanfattning : The iron-chromium (Fe/Cr) catalyst is used for high-temperature water-gas shift (HT WGS) reaction. A major concern using the Fe/Cr catalyst is that it contains hexavalent chromium (Cr+6) which is a potent carcinogen causing health and environmental issues. LÄS MER

  5. 4. Effect of sweeteners on acrylamide formation in extruded breakfast cereals

    Kandidat-uppsats, SLU/Department of Molecular Sciences

    Författare :Linnéa Gustafsson; [2021]
    Nyckelord :acrylamide; ; breakfast cereals; free asparagine; fruit juice concentrate; sweetener;

    Sammanfattning : Acrylamide is a possible carcinogen to humans, formed upon heat-treatment of carbohydrate-rich foodstuffs via the Maillard reaction. Reducing sugar and the amino acid asparagine are the primary precursors for acrylamide formation, of which free asparagine is the limiting factor. LÄS MER

  7. 5. Salt-roasting of snack pellets : a study on the effects of a novel processing technique on product quality attributes and acrylamide content

    Kandidat-uppsats, Högskolan Kristianstad/Fakulteten för naturvetenskap

    Författare :Malin Ekdahl; [2020]
    Nyckelord :Sensorisk analys; triangel test; akrylamid; salt; fett; puffade snacks; snack pellet; snacks bearbetning;

    Sammanfattning : Snacks are often associated with chips and expanded snack products that generally known for their characteristic texture. These products are normally high in calories with a low content of nutrients and are therefore perceived as unhealthy by many consumers. LÄS MER
