CHAPTER 6: Supplement Delivery at the Nanoscale

This chapter covers nanodelivery systems developed specifically for use in the food industry. The different types of nanodelivery system are described, including the techniques and materials used to synthesize these particles, and their particular advantages and disadvantages. The release mechanisms of bioactives from nanodelivery systems are covered, as well as the interaction of the nanocarriers with foods and the impact of gastrointestinal conditions on the stability, functionality, and bioavailability of the nanoscale delivery systems and the delivered load. The biological fate of these nanomaterials during absorption, distribution, metabolism, and excretion is discussed, and some information on the bioavailability of the nanodelivered bioactive, in relation to consumer safety, is also included.
