Phytonutrient bioaccessibility and metabolism in vitro and in vivo

Abstract

Mangoes and bananas, two of Queensland's major tropical crops are sources of bioactive phytonutrients linked to dietary health based on antioxidant, cardio-protective and vasodilatory properties. Bioaccessibility of macro-, micro-and phytonutrients from whole foods is first determined by mastication followed by gastrointestinal liberation from food matrices (cell wall and membrane). Intact plant cell walls effectively encapsulate cellular components e.g. starch, lipid, protein, carotenoids and polyphenols, physically preventing viii Chapter 4 Part B.
