Special Issue Information

Dear Colleagues,

Oils and fats, as an important source of fat-soluble nutrients, essential fatty acids, as well as energy, are consumed daily by humans. Lipids from natural sources are mainly composed of triacylglycerol (95%~98%) and minor components, such as tocochromanols, phytosterols, phenolic compounds, and squalene, and previous studies have observed that most of these minor components have antioxidant properties. Moreover, the current research mainly focuses on lipid’s physiological and biological activities and their possible relationships with human health. In addition, in the food industry, oils and fats could provide numerous lipid-based foods, such as bread, biscuit, chocolate, margarine, and frozen desserts, with a desirable texture, flavor, and taste. However, the properties, quality and oxidative stability of food products are significantly influenced by fatty acid and triacylglycerol composition due to their different physicochemical properties, including melting behavior, crystallization, solid fat content, and interfacial and rheological properties. 

This Special Issue entitled “Lipids in Food Chemistry, 2nd Edition” includes original research articles, reviews, and short communications related to the health benefits, physicochemical properties, synthesis, processing, oxidation, nutrition and biotechnology of lipids but are not limited to the above.

The process of lipid crystallization influences the characteristics of lipid. By changing the chemical composition of the lipid system, the crystallization behavior could be controlled. This review elucidates the internal factors affecting lipid crystallization, including triacylglycerol (TAG) structure, TAG composition, and minor components. The influence of these factors on the TAG crystal polymorphic form, nanostructure, microstructure, and physical properties is discussed. The interplay of these factors collectively influences crystallization across various scales. Variations in fatty acid chain length, double bonds, and branching, along with their arrangement on the glycerol backbone, dictate molecular interactions within and between TAG molecules. High-melting-point TAG dominates crystallization, while liquid oil hinders the process but facilitates polymorphic transitions. Unique molecular interactions arise from specific TAG combinations, yielding molecular compounds with distinctive properties. Nanoscale crystallization is significantly impacted by liquid oil and minor components. The interaction between the TAG and minor components determines the influence of minor components on the crystallization process. In addition, future perspectives on better design and control of lipid crystallization are also presented. Full article
