This brief presents the state of the art on enzymatic synthesis of structured triglycerides and diglycerides, focusing on glycerol as the substrate and covering interesterification of vegetable oils in one and two steps. It critically reviews the available literature on enzymatic and chemo-enzymatic synthesis of di- and triglycerides in one or more steps. The effects of the structure, length and unsaturation of the fatty acids are carefully considered, as well as the inhibitory potential of highly unsaturated complex fatty acid structures. The brief also addresses acyl migration and the use of adsorbents, taking into account the most recent literature and presenting the problem in an industrial context. It discusses experimental and analytical problems concerning, e.g. the lab scale and the scaling up to bench and pilot plants. Several examples are presented, and their successes and failures are assessed. Biocatalysts based on lipases are analyzed with regard to problems of immobilization, stability on storage time and activity after multiple uses. The need for specific Sn-2 lipases is presented and strategies for optimizing Sn-2 esterification are discussed. Lastly, practical aspects are examined, e.g. lipase “leaching” with loss of activity, taking into account the latest findings on continuous and batch reactor configurations and presenting the advantages and disadvantages of each.

Focuses on fats which have recently been synthesized and which are currently used in diseased states or have potential for clinical nutrition such as partial glycerides, structural lipids, salatrims, and triglycerides with specified fatty acid combinations or enriched in specific fatty foods. Chapters address technological aspects of fat modification, the synthesis of foods with specific nutritional properties, aspects of the metabolism of structural modified lipids, and the effect of fat structure on lipemia and lipoproteinemia.

This book addresses special lipids produced by chemical and enzymatic interesterification and explores the interesterification process and its crucial role in the modification of oils for various applications. The book discusses the chemical and enzymatic aspects of this process, providing an in-depth understanding of its mechanism, benefits, and limitations. The book covers key concepts such as the mechanism of interesterification, the use of immobilized lipases in enzymatic interesterification, and current applications of interesterification in fats and oils. Particular attention is given to acidolysis, alcoholysis, glycerolysis, and transesterification - the four types of interesterification reactions, and to the advantages and drawbacks of both enzymatic and chemical interesterification. In this book, the authors address critical questions like the fate of fatty acids from interesterified lipids after consumption and their long-term health effects. Readers will also learn more about the current applications of interesterification in fats and oils, including special lipids like plastic fats, human milk fat substitutes, structured lipids enriched with essential fatty acids, cocoa butter equivalents and substitutes, and low-calorie structured lipids. Aimed at researchers and professionals in food science, this book offers valuable insights into the production of various specialty fats through enzymatic interesterification, thereby equipping readers with the knowledge to innovate in the field of food applications. Readers with a background in food chemistry will benefit from its detailed explanation of lipase-catalyzed synthesis and the use of alkali metals in interesterification.

The increase in the amount of glycerin in the market is a burden for all producers, especially those operating in the biodiesel sector: reuse options are in fact limited for the management of this by-product. Glycerol enhancement has therefore become a priority to improve the sustainability of the biodiesel industry. Nevertheless, the multifunctionality of glycerol makes it a promising precursor for different types of production (fuel/biofuel, chemical products). This conversion has therefore become a subject of multifaceted research that requires an exchange of knowledge across many sectors. In this book, different disciplines (chemistry, biology, engineering, etc.) have been taken into consideration to propose an interdisciplinary point of view on different aspects.

Oils and fats have a major impact on the nutritional and sensory quality of many foods. Food manufacturers must often modify lipid components or ingredients in food to achieve the right balance of physical, chemical and nutritional properties. Modifying lipids for use in foods reviews the range of lipids available, techniques for their modification and how they can be used in food products.Part one reviews vegetable, animal, marine and microbial sources of lipids and their structure. The second part of the book discusses the range of techniques for modifying lipids such as hydrogenation, fractionation and interesterification. Finally, part three considers the wide range of applications of modified lipids in such areas as dairy and bakery products, confectionary and frying oils.With its distinguished editor and international range of contributors, Modifying lipids for use in foods is a standard reference for dairy and other manufacturers using modified lipids. - Reviews the range of lipids available - Asseses techniques for modifying lipids such as fractionation and interesterification - Considers the wide range of applications of modified lipids
