Special Issue Information

Dear Colleagues,

I am pleased to invite you to submit your recent studies in the field of “Research Progress on Functional Lipids and Their Applications in Health Food Systems” to a Special Issue of Molecules.

In today's food industry, there is a growing emphasis on health, nutrition, and sustainability, which is driving research into functional lipids and their applications in health food systems. Functional lipids are essential for food formulation, enhancing sensory properties, and improving nutritional value. As consumer preferences shift toward healthier and more sustainable options, the study of functional lipids has become a critical area of investigation.

Key research directions include lipid crystallization and oxidation, enzymatic lipid modification, and the development of structured emulsions and lipid capsules that deliver health benefits. Despite significant advancements in our understanding of lipid chemistry and functionality, there is still a pressing need for innovative processing techniques and modifications that can enhance the nutritional profiles and sensory qualities of health food products.

This Special Issue aims to provide a platform for researchers to showcase the current and recent developments in the field of functional lipids and their applications in health food systems. We welcome original research papers and review articles that explore various aspects of lipid processing, modification, and application in the food industry.

In the glycerolysis process for diacylglycerol (DAG) preparation, free lipases suffer from poor stability and the inability to be reused. To address this, a cost-effective immobilized lipase preparation was developed by cross-linking macroporous resin with poly (ethylene glycol) diglycidyl ether (PEGDGE) followed by lipase adsorption. The selected immobilization conditions were identified as pH 7.0, 35 °C, cross-linking agent concentration 2.0%, cross-linking time 4 h, lipase amount 5 mg/g of support, and adsorption time 4 h. Enzymatic properties of the immobilized lipase were analyzed, revealing enhanced pH stability, thermal stability, storage stability, and operational stability post-immobilization. The conditions for immobilized enzyme-catalyzed glycerolysis to produce DAG were selected, demonstrating the broad applicability of the immobilized lipase. The immobilized lipase catalyzed glycerolysis reactions using various oils as substrates, with DAG content in the products ranging between 35 and 45%, demonstrating broad applicability. Additionally, the changes during the repeated use of the immobilized lipase were characterized, showing that mechanical damage, lipase leakage, and alterations in the secondary structure of the lipase protein contributed to the decline in catalytic activity over time. These findings provide valuable insights for the industrial application of lipase. Full article
