Muligheder og barrierer for brug af økologiske ingredienser i skolemadsordninger
The report considers the following aspects:
1. The arguments that two Danish municipalities mention in relation to using, or choosing not to use, organic ingredients in school meal systems.
2. The reasons for school meal companies to use, or not to use, organic ingredients in their production as well as the challenges they meet in relation to organic food.
In relation to analyzing how the municipalities organize the school meal systems, we include issues such as the most common arguments used to legitimize their choice of meal system, objectives, involvement of users, most relevant decision makers etc. In the case of school meal companies, the project includes an analysis of barriers such as economy, supply of organic ingredients, structural conditions, cooperation with municipalities etc

Supplementation of laying-hen feed with annatto tocotrienols and impact of α-tocopherol on tocotrienol transfer to egg yolk and tocopherol and annatto tocotrienol distribution analysis in laying-hen body
Laying-hens efficiently transfer nutrients from their feed to the resulting eggs, and nutrients from feed are distributed in many organs and tissues for various uses. Annatto is the only known source of tocotrienols (T3s) (gamma-T3 ~10% and delta-T3 ~90%) without alpha-tocopherol present. The T3s have many health benefits including lowering cholesterol. The objective of this research was to study the effect of alpha-tocopherol on the transfer of T3s to eggs and various organs and tissues in the body of the laying-hen. To do so, laying-hens were fed treatment diets for 7 weeks supplemented with annatto T3s in the presence and absence of alpha-tocopherol. The diet regimens were a control diet with not supplementation and three diets with 2000 ppm annatto extract and added alpha-tocopherol at 200 and 1000 ppm.
No significant differences were found in egg production or egg yolk properties (moisture content of moisture, lipid, phospholipids, fatty acids, or cholesterol). Significant differences (p\u3c0.05) were found in feed intake, yolk viscosity, sensory yolk flavor and color, and transfer efficiency of tocopherols and T3s to the egg yolks.
Alpha-tocopherol was transferred more efficiently (21.19-49.17%) than gamma-T3 (0.50-0.96%) or delta-T3 (0.74-0.93%) to the egg yolks. Addition of 1000 ppm of alpha-tocopherol decreased the transfer of gamma-T3 (by 23.76%) but it did not impact the transfer of delta-T3 to the egg yolk. The addition of annatto T3s did not significantly impact the cholesterol content of the laid eggs.
A total of 18 organs or tissues (skin, fat pad, liver and gall bladder, heart, oviduct, forming yolk, laid yolk, lungs, spleen, kidney, pancreas, gizzard, digestive tract, brain, thigh, breast, manure, and blood) were collected after 7 weeks of feeding the diets. Tissue weights, moisture content (except for manure), lipid, alpha-tocopherol, gamma-T3, delta-T3, cholesterol, and fatty acid composition of extracted lipids in the collected organs and tissues (except for blood) were determined.
Tissue weights, moisture content, and lipid content did not change significantly with feed supplementation across treatments, except that the liver became heavier with increased supplementation. Minimal changes were found in the fatty acid composition, except in the fat pad, oviduct, brain, and manure.
Overall, the main organs that accumulated the supplemented forms of vitamin E were fat pad, liver and gall bladder, oviduct, forming yolks, laid yolks, kidney, brain, thigh, and breast. Much of annatto supplement (gamma-T3 and delta-T3) was detected in the manure (\u3e90%), indicating that most was excreted and not used by the hen. In some tissues (brain and oviduct) a significant increase in polyunsaturated fatty acids was seen with increased supplementation. Alpha-tocopherol impacted the transfer of gamma-T3 to the forming and laid yolks, but did not impact delta-T3 transfer. No significant differences were found in the cholesterol in the liver, kidney, laid yolks, breast meat, oviduct, or thigh meat, except for cholesterol reduction in the heart based on as-is tissue weight. Blood samples showed large variation among individual hens with no significant differences in total cholesterol, HDL, or total triacylglycerols.
The results indicate that supplementing hen-laying feed with annatto T3s and alpha-tocopherol can alter the vitamin E profile and its distribution among the laid eggs and laying-hen organ and tissues (especially in the liver and egg yolks). Therefore it is possible to enhance the nutritional profile of the egg to further benefit the consumers and to increase oxidative stability of various organs and tissues
Organic and conventional public food procurement for youth in Denmark
This report is the first mapping of the activities and state-of-the-art on public organic food procurement for youth. The report, on the Danish activities, comes together with similar reports from Finland, Italy and Norway. These four reports will inform a comparative analysis conducted by DTU in workpackage 2 of the iPOPY project.
The major focus of the reports is school meals and the use of and potentials for organic products in this setting. But also other important settings than schools are included. The perspectives of the reports are on the policies and the policy processes influencing the extension of organic school meals.
The report is produced within the project “innovative Public Organic food Procurement for Youth”, iPOPY, and will be updated and revised during the project period (2007-2010)
Event Related Electrical Potentials Recorded From The Brain Prior To The Initiation Of Speech
This research will explore the neurologic pathways that occur before the initiation of speech. The basis for this project and the research component will include the electrical potentials along the speech production pathway. The subjects will be given a target consonant-vowel (CV), and their speech production will be recorded simultaneously with their neural activity. We will be attempting to record the electrical signals from the cortex. Subjects will be neurotypical. Benefits of this research will include an increased understanding of normal neuro-electrical properties of the speech production pathway. The clinical benefit will include understanding variations from the norm with application to neuro-motor disorders
The Planar Electrode Linear Ion Trap
We present a linear type ion trap consisting of metal lines that are lithographically patterned onto two ceramic substrates. Trapping fields are realized by applying specific voltage potentials to each line. This arrangement allows miniaturization approaches that are immune to surface roughness issues and increased complexities of precision machining of electrode surfaces. We also present how these traps allow a thorough study of higher order multipoles and their effect on mass analyzer performance
