Nutrient Analysis in Foods
Last Updated: 2026-02-05 16:14:30
Abstract
In this practical course, different meals are prepared and then analysed for nutritional content in the laboratory. Based on these results, the nutritional value of each meal is critically evaluated and discussed, and the students must design a reformulated meal that has a superior nutritional content, justifying their choices.
Objective
The objectives of this practical course include learning about and having experience with analytical methods to determine micronutrient and phytonutrient content in foods, critical evaluation of analytical results, critical comparison with values from food composition tables, interpretation in relation to nutritional value of meals, and creative skills in the design a new meal.
Content
The practical course Nutrient Analysis in Foods includes meal preparation (a half day in late 2023; date to be defined) and chemical analysis of four meals from four different types of diets (students will work in groups; one meal per group). The content of specific micronutrients and secondary phytonutrients (polyphenols and phytic acid) are analysed using common analytical methods. The analytical results are compared with calculated data from food composition databases using nutrition software and then critically evaluated. The nutritional values of the meals are discussed, including a discussion of nutrient bioavailability. The students are also expected to reformulate their meal to a more nutritional version, justifying their choices using evidence from peer-reviewed literature. Students will prepare a written report to summarise their findings and conclusions, supported by an oral presentation with colloquium in the group. The practical course is accompanied by lectures on the basic principles of analytical chemistry that will be given in person with further details made available via Moodle.

Nutrient Analysis in Foods
Permission from lecturers required for all students.
Block course from 29. January 2024 in the Laboratory of Nutrition and Metabolic Epigenetics ETH Zentrum labs in LFV on D floor.
Between 29. January 2024 and 7 February 2024, students will take lectures in person, a written test via Moodle, and gain practical experience in the laboratory. Students will work in groups of 4.
Oral presentations of student results, per group, will take place on 9. February 2024 (afternoon) and a written report will be submitted by 16. February 2024. The detailed program will be announced separately.
This course also includes an obligatory half-day cooking preparation on a day in 2023 (date to be confirmed).
All learning materials will be available for students on Moodle.
