Collaborative project: Research on basic principles for the production of breakfast cereals with reduced energy density enriched in dietary fibre and polyphenols - subproject 1 (Zerealien)
Project
Project code: 2819107316, MRI-LBV-08-1005-686 31 Zerealien
Contract period: 01.07.2016
- 30.04.2019
Budget: 236,152 Euro
Purpose of research: Experimental development
Frequent consumption of carbohydrate-rich food with a high glycemic index appears to increase the risk for obesity, type 2 diabetes, and other metabolic disorders and diseases, e.g. cardiovascular diseases and certain forms of cancers. Consumption of functional breakfast cereals with high contents of specific types of dietary fibre and phytochemicals (e.g. polyphenols) and reduced energy density may lower these risks. The main aim of the joint project is to study the scientific background for the application of two novel food processing techniques: (1) high-temperature short-time extrusion (HTST) will be studied to design dietary fibre-rich breakfast cereals with reduced energy density, high contents of bioactive polyphenols and an optimised sensory quality (Work Packages; WPs2,3), (2) high-pressure high-temperature extraction (HPHT) will be investigated to extract dietary fibre and bioactive polyphenols from the by-product of chokeberry juice production (pomace) by using subcritical water, thus avoiding organic solvents (WP1). Furthermore, the optimised extruded products and extracts prepared by both processing methods will be analysed in detail for/used for: (a) changes in the molecular structures of dietary fibre components as influenced by HTST and HPHT processing (WP4), (b) nutritional quality aspects (e.g. contents of dietary fibre, sugars, and polyphenols) (WP1), (c) digestibility of carbohydrates and in vitro bioavailability of polyphenols (WP5), (d) in vivo tests (human intervention study) measuring blood glucose levels and the glycemic index after consumption of selected samples based on the results of the in vitro tests (WP5).
