2. 1. Oxidation of fish lipids during gastrointestinal in vitro digestion

   Author : Karin Larsson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TBARS; HHE; salmon; lipids; TIM; fish; HNE; in vitro digestion; gastrointestinal; aldehydes; cod liver oil; n-3 PUFA; herring; lipid oxidation; MDA;

   Abstract : Fish and many other marine organisms, contain long chain n-3 polyunsaturated fatty acids (LC n-3 PUFA), e.g. eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). EPA and DHA has shown beneficial effects in diseases related to inflammatory processes, such as cardiovascular diseases. READ MORE

4. 2. Gliadin-Blocking Peptides In vitro assessment of their potential to alleviate celiac disease development

   Author : Karolina Hoffmann; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; high-gliadin affinity blocking peptides; Caco-2 cells; in vitro digestion; tissue transglutaminase; celiac disease; gliadin; α-amylase trypsin inhibitors;

   Abstract : This thesis work aimed to investigate the potential of synthetic peptides as agents to block wheat prolamins (gliadins) that trigger the development of symptoms in celiac disease. The first step of this investigation included selection and synthesis of peptides with high affinity to gliadins and assessment of the potential of these so-called blocking peptides to limit gliadin reactivity in vitro.

5. 3. Antioxidative Properties of Herring (Clupea harengus) Press Juice in Food, In Vitro and In Vivo Model Systems

   Author : Thippeswamy Sannaveerappa; Chalmers tekniska högskola; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; antioxidants; monocytes; washed cod mince; Clupea harengus; LDL oxidation; press juice; oxidation; ORAC; hemoglobin; alpha-tocopherol; herring; in vitro digestion.;

   Abstract : Some species like herring (Clupea harengus) are currently under-utilized due to their small size, dark colour and susceptibility to lipid oxidation. Our hypothesis has been that the high susceptibility of herring to oxidation makes it well equipped with natural antioxidants, both fat and water soluble ones. READ MORE

6. 4. Oxidation of marine oils during in vitro gastrointestinal digestion and its effects on stress in human intestinal Caco-2 cells

   Author : Cecilia Tullberg; Chalmers tekniska högskola; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; lipid oxidation; human digestive fluids; LC n-3 PUFAs; Caco-2 cells; marine oils; HNE; MDA; in vitro digestion; HHE; gastrointestinal; aldehydes;

   Abstract : Marine oils are attracting public interest due to the preventive effects, e.g., on inflammation, which are linked to the long-chain n-3 polyunsaturated fatty acids (LC n-3 PUFAs). However, LC n-3 PUFAs are highly susceptible to oxidation, which could interfere with their positive effects. READ MORE

7. 5. Improving vitamin A nutrition in low-income countries. In vitro bioaccessibility of provitamin A carotenoids in biofortified orange-fleshed sweet potato

   Author : Anton Bengtsson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; bioaccessibility; β-carotene; biofortification; provitamin A carotenoids; coherent anti-Stokes Raman scattering microscopy; vitamin A deficiency; food processing; orange-fleshed sweet potato; in vitro digestion; Caco-2 cells;

   Abstract : Vitamin A deficiency is a major nutritional disorder in a large number of low-income countries that is caused by an inadequate intake of preformed vitamin A and provitamin A carotenoids in the diet. The objective of the present thesis was to evaluate orange-fleshed sweet potato (OFSP) as a biofortified food source of provitamin A carotenoids with a potential to be included in a diet for alleviating vitamin A deficiency.
