The physical properties associated with the saturated and trans fats obtained through partial hydrogenation of vegetable oils (PHVOs) provide the solid fat content, melting and textural properties that consumers require in food products like butter, margarines, vegetable creams, spreads, and confectionary fats. However, saturated and trans fats increase low density lipoprotein, while trans fats also lower high-density lipoprotein serum levels. These indicators increase the risk of developing cardiovascular disease, type II diabetes, stroke, and have recently been associated with metabolic syndrome. Consequently, regulatory agencies worldwide have passed legislation restricting the addition of PHVOs and their derivatives (i.e., shortenings) to food products. This has lead research groups worldwide to investigate different mechanisms to provide structural and physical properties to edible, healthy unsaturated oils. The overall objective is to achieve similar functional properties to those provided by PHVOs and shortenings to food products.
This book encompasses the work of leading researchers discussing, from a scientific and technological perspective, the latest and most innovative approaches to structure edible oils without the use of trans fats. Additionally, the authors discuss practical uses and technical limitations associated with the use of ‘structured edible oils’ in different food systems. Appealing to researchers and professionals working in lipid science, food chemistry and fat metabolism, it fills the gap in the literature for a book in this fast-changing field.
