- International studies have noted shortcomings in food safety knowledge and behaviour among university students. In general students do not constitute a pronounced risk group but there are wider implications. In a foreseeable future some of them will become pregnant and a majority will be responsible for vulnerable groups in their near environment. A crucial question exists, therefore, about their food safety knowledge and safe food handling practices. The aim of this study is to investigate food safety knowledge, sources thereof and self-reported food safety behavior among university students in Sweden. A quantitative study design using a web-based questionnaire was chosen as the data collection method. The questionnaire was distributed through social media and e-mail. Among the 606 respondents from 24 Swedish universities 80% were 18-30 years and 78% were women. The average number of correct answers on the knowledge questions was 7.61 out of 12 (63.4%). The foremost source of food safety knowledge was "Family and friends" (45%). Just 21.1% reported Food safety education as a source, although 35.6% had experience of a course in food hygiene/safety and/or microbiology. Respondents who reported "Family and friends" to be the foremost food safety source of knowledge also got a significantly lower rate of correct answers. Students who estimated their food safety knowledge to be good also had more correct answers. Experience of food safety education at secondary school/university/working place/polytechnic school significantly correlated with more correct answers on the knowledge questions and indicated a safer self-reported behaviour. Those with fewer correct answers also reported more unfavourable behaviours. The present study indicates that education promotes more optimal behaviors. The authors would suggest a more systematic food safety education at younger ages.

Characterization of the properties of Pediococcus parvulus for probiotic or protective culture use.
- 2010
-
Ingår i: Journal of Food Protection. - 0362-028X. ; 73:5, s. 960-966
-
Tidskriftsartikel (refereegranskat)abstract
- Pediococcus parvulus 2.6 (previously Pediococcus damnosus 2.6, here confirmed as P. parvulus by 16S DNA sequencing) displayed antibacterial activity toward several bacterial species, including isolates found as contaminants in oats, herein genetically identified as Bacillus cereus. No inhibition of Listeria monocytogenes was found under the conditions used. Antibacterial activity was retrieved after ammonium sulfate or acetone precipitation showed it to be peptide mediated. P. parvulus 2.6 has previously shown good technological properties in oat-based products. This, together with the currently found inhibition of food spoilage microorganisms like B. cereus, makes it suitable as a food protective culture. Survival trials of P. parvulus 2.6 at conditions mimicking the gastrointestinal tract were prompted by previously found cholesterol-lowering effects in humans after consumption of oat products cofermented by using P. parvulus 2.6 and Bifidobacterium spp. Viability was measured with in vitro, gutlike simulations at 37 degrees C. High survival was shown under two of three conditions (gastric juice, bile, and small intestine juice), defined as main obstacles of the gastrointestinal tract. The critical step was bile exposure. At a concentration of 20%, viability was low, but 0.3% bile (mean concentration in the intestine) did not have a major influence on growth. Viability of P. parvulus 2.6 was significantly decreased in gastric juice at pH 1.5 (with pepsin), but it was not significantly affected at pH 2.5, and was also improved at a lower pH in 20% oat milk. Viability was judged sufficient for colonization at gutlike conditions, qualifying the strain for further probiotic studies.

From carbohydrates to fat : Trends in food intake among Swedish nutrition students from 2002 to 2017
- 2020

Ingår i: PLOS ONE. - : Public Library of Science. - 1932-6203. ; 15:1, s. 1-14

Tidskriftsartikel (refereegranskat)abstract
- Earlier studies have implied a change in dietary habits of the Swedish population towards a low carbohydrate, high fat diet. Questions have been raised about the development in recent years and potential health effects. We have investigated the dietary intake of Swedish female students enrolled in a university nutrition course between 2002 and 2017. The students carried out self-reporting of all food and drink intake over one weekday and one weekend day. Intake of macronutrients (E%) and micronutrients were calculated for the whole period while statistical analysis was performed for changes between 2009 and 2017 (729 women). Results showed significant changes in carbohydrate intake (from 47.0 to 41.4 E%) and fat intake (from 31.7 to 37.5 E%). Carbohydrate intake was significantly lower than the Nordic Nutrition Recommendations (45-60 E%). However, daily fiber intake remains high (3.0 g/MJ) in a national context, and intake of vitamin D and folate appears to increase during the period. The results suggest that the observed national transition from carbohydrate to fat intake persists, and that it might be especially evident among individuals interested in food and nutrition. Considering the fiber and micronutrient intake, the change is not necessarily unfavorable for this particular group.

Substrate-dependent production and some properties of a thermostable, α-galactosidase from Rhodothermus marinus
- 2000
-
Ingår i: Biotechnology Letters. - 0141-5492. ; 22:8, s. 663-669
-
Tidskriftsartikel (refereegranskat)abstract
- α-Galactosidase activity in Rhodothermus marinus is dependent on the composition of the growth media. A maximum of 46 μU g-1 cell dry weight was obtained using minimal medium with galactooligo- or polysaccharides as single carbon source. An enzyme hydrolysing both high and low molecular weight galacto-saccharides was partly purified from the cell fractions. The molecular weight was 200 kDa (native) and 50 kDa (monomer). It was optimally active at 85°C, with a half-life of 2 h at 75°C, and had a broad pH range (4-8).

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- While the Swedish nutrition recommendations have been kept relatively constant in recent years, public attitudes to different diets have been swinging faster. The National food survey (Riksmaten), being performed in Sweden only once per decade, cannot identify any corresponding rapid changes in diets. Hence, our understanding of potential fluctuations is limited. During the last 15 years, nutrition students at the Linnaeus University (formerly University of Kalmar) have reported their food intake in the context of the course Diet, Nutrition and Health 7,5 hp. The result is an extensive data set comprising more than 1100 individuals and over 2500 days of food intake reports, and although not originally intended or designed as a study, it became apparent that these data could be of interest as an indicator for national dietary trends. Food intake was reported (by weighing or estimating the amounts) for two weekdays and one weekend day per student, along with age, length, sex and weight. Food intake was translated to nutrient intake using Dietist Net software (Kost & Näringsdata). Admittedly, the data set has some validity problems: the students differ from the Riksmaten study groups in mean age and geographical distribution, and all data was collected during March-April. As students in a nutrition course, they can also be expected to be more interested and more knowledgeable in the nutrition subject than the average person. Nevertheless, the results clearly demonstrate a substantial change in nutrient intake from 2006 and onwards, where the energy from carbohydrates decreased from above 50% to below 40%, and where the energy intake from fat increased from about 25% to 36%. Further details, such as the effects on the intake of selected micronutrients, will be presented.

Tidskriftsartikel (populärvet., debatt m.m.)abstract
- DN.DebattRunt 500 000 människor drabbas enligt beräkningar av matförgiftning i Sverige varje år. Bristande hygienkunskaper i hushållen är en av orsakerna. Nu är det dags för en utökad timplan i hemkunskap för att Sverige skall få medvetna konsumenter, minskat matsvinn och färre fall av matförgiftningar, skriver en grupp experter inom området.

Energianvändning. Konsumenters beslut och agerande.
- 2009
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Skriften inleds med en genomgång av kunskapsläget kring faktorer som påverkar kunders attityder, beteende samt faktorer kring beslut om inköp av vitvaror och investeringar i ny uppvärmningsteknik eller byggnadsåtgärder i bostaden. I översikten presenteras även kortfattat resultat kring ett antal svenska och internationella interventionsprojekt för energieffektivisering i hushåll. Forskningen i detta program har som fokus hushållens energianvändning för uppvärmning av bostaden. Fastighetsägare och förvaltare till flerbostadshus samt hushåll som bor i privata småhus ingår i studien. Förutom hushållens attityder och beteende kring energieffektivisering i hemmet analyseras hushållens kunskap och förmåga att påverka sina elkostnader genom att agera, dvs. ändra sitt avtal med eller byta elleverantör utifrån den information som förmedlas till dem. Forskningsprogrammet innehåller tre delprojekt nämligen Värme i bostäder; Att värma bostäder och Hushåll på elmarknaden.
