Effect of food processing on the bioaccessibility of nutrients. Investigations with the tiny-TIM system
Project
Project code: MRI-PBE-08-1010-resorption-nährstoffe
Contract period: 01.03.2018
- 31.12.2023
Purpose of research: Experimental development
In vitro-gastrointestinal models such as the tiny-TIM (TNO Intestinal Model) system provide the opportunity to simulate sub-processes of gastrointestinal digestion similar to conditions in humans. Besides examining the release of nutrients from the food matrix (individual products up to complex meals), it is possible to estimate the amount of a nutrient available for absorption (bioaccessibility). Within the project, this system is being applied to investigate the digestibility and bioaccessibility of important macro and micronutrients from various food matrices produced within the several inter-institutional projects. In this context, alternative protein sources (e.g. insect flour) but also products from projects such as aronia pomace-enriched starch extrudates or oleogels are investigated initially. The literature and our own results showed that food processing can have a significant impact on food digestibility and nutrient bioaccessibility. Therefore, the influence of processing methods and their parameters such as the thermal treatment or extrusion of corn starch/aronia pomace or of insect products on digestibility and biaccessiblity will be investigated.
