ABSTRACT
Wheat aleurone our (ALF) is a novel food product or ingredient made from the aleurone layer of cells in the wheat grain (Figure 19.1). ALF has the potential to make an important contribution to optimal nutrition because it contains signicant amounts of naturally occurring nutrients including (a) minerals such as magnesium, calcium, iron, and zinc, (b) dietary ber, (c) protein, (d) antioxidant phenolic compounds, and (e) B vitamins including folate (Tables 19.1 and 19.2) [1-3]. The aleurone cells, together with the germ, contain the wheat grain’s essential nutrients required for the growth and development of the embryo [4, 5]. Because the bran fraction of wheat contains the aleurone layer of cells, the phytochemicals, vitamins, minerals, ber, and protein in aleurone cells are lost when wheat grain is rened to make white our. Consequently, in recent years there has been an interest in devising novel milling technologies to purify the aleurone fraction of the wheat grain
