  1. 1. Reduction of Acrylamide in Reject Water from Sludge Dewatering

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Martina Aspegren; [2023]
    Nyckelord :Water treatment techniques; Ozonation; Moving bed biofilm reactor; Trickling filter; Biological degradation; Lake Mälaren; attenreningstekniker; Ozonering; Biofilmreaktor med rörlig bädd; Biobädd; Biologisk nedbrytning; Mälaren;

    Sammanfattning : Norrvatten produces and delivers drinking water to approximately 700 000 people in the northern part of the Stockholm region in Sweden. In their water treatment plant Görvälnverket, water from Lake Mälaren is purified. During the purification, sludge is produced. To be able to use the sludge as landfilling material, it must be dewatered. LÄS MER

  3. 2. 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

  4. 3. 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

  5. 4. Acrylamide in oat products : a literature survey

    Kandidat-uppsats, SLU/Department of Molecular Sciences

    Författare :Edvin Nåbo; [2019]
    Nyckelord :oats; acrylamide; free asparagine;

    Sammanfattning : Acrylamide can be formed during heating of cereals. Oats have the second highest acrylamide forming potential of rye, wheat, barley and oats. Several studies have found high levels of acrylamide in oat products that exceed the benchmark limits within the EU. These limits might be strict limits in future which every food producer needs to follow. LÄS MER

  7. 5. Polyakrylamidhydrogel : en vetenskapligt baserad behandling av osteoartrit hos häst?

    Kandidat-uppsats, SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Författare :Rebecka Karlsson; [2016]
    Nyckelord :polyakrylamidhydrogel; osteoartrit; artificiellt brosk; akrylamid; polyacrylamide hydrogel; osteoarthritis; artificial cartilage; acrylamide;

    Sammanfattning : En vanlig orsak till hälta hos häst är osteoartrit (OA), en ledsjukdom där ledbrosket kan luckras upp så mycket att det subkondrala benet blottläggs. Nyligen introducerades en medicinteknisk produkt innehållande polyakrylamidhydrogel (PAAG) på marknaden för intraartikulär (ia) behandling av OA. LÄS MER
