Special Issue Information

Dear Colleagues,

Marine products represent a significant protein resource, and yet their low- or utilization rates lead to substantial resource waste. This Special Issue will concentrate on the nutritional investigation of proteins derived from marine products or their by-products, systematically elucidating their mechanistic roles at the cellular, animal, digestive, and gut microbiota levels. The main research outlines are as follows: (1) Extraction technologies, physicochemical properties, and bioactive functionalities. (2) Regulatory effects on cellular proliferation, metabolism, growth performance, gut microbiota levels, and signaling pathways. (3) Digestive characteristics, functional activities of their digestion-derived products, and modulatory effects on gut microbiota composition.

This Special Issue aims to unveil the nutritional value and application potential of proteins derived from , providing theoretical foundations for the development of healthy food (e.g., hydrogels, capsule, or emulsion/powder). It also seeks to advance the efficient utilization and sustainable development of marine resources.

In this study, an efficient and eco-friendly method was developed for continuous liquid–liquid extraction of lutein from microalgae Chlorella vulgaris. By employing a limonene-based biphasic liquid system, high-purity lutein was successfully obtained from the crude extract in a single run via centrifugal partition chromatography (CPC). Evaluation and optimization results demonstrated that limonene could effectively serve as a replacement for n-hexane as the solvent system for lutein extraction, exhibiting natural renewability and minimal environmental impact. Furthermore, the elution–extrusion operation mode was employed to fully exploit the liquid nature of the stationary phase in the extraction process, allowing for continuous sampling and separation without interruption. This proposed protocol offers a sustainable and environmentally friendly alternative for extracting valuable ingredients from microalgae biomass, demonstrating its potential as a scalable solution for producing lutein-enriched ingredients applicable to functional foods and nutraceuticals.
