Measuring and Controlling Food Structure Breakdown and Nutrient Absorption
edited by
D. Julian McClements

Designing Functional Foods: Measuring and Controlling Food Structure Breakdown and Nutrient Absorption covers the following key areas:

  • digestion and absorption of food components including oral physiology and gut microbial ecology
  • advances in methods to study food sensory perception assessing criteria such as simulation of flavour released from foods
  • the implications for the design of functional foods including optimising the flavour of low-fat foods and controlling the release of glucose
  • new methods and future trends

Part One examines oral physiology and gut microbial ecology, and the digestion, absorption and physiological effects of significant food components, such as lipids, proteins and vitamins.

Part Two covers advances in methods to study food sensory perception, digestion and absorption, including in vitro simulation of the stomach and intestines and the use of stable isotopes to determine mineral bioavailability.

The implications for the design of functional foods are considered in Part Three. Controlling lipid bioavailability using emulsion-based delivery systems, designing foods to induce satiation and self-assembling structures in the GI tract are also covered in this section.
