High-quality fish oil for human consumption requires low levels of toxic elements. The aim of this study was to compare different oil extraction methods to identify the most efficient method for extracting fish oil of high quality with the least contamination. The methods used in this study were Soxhlet extraction, enzymatic extraction, wet reduction, and supercritical fluid extraction. The results showed that toxic elements in fish oil could be reduced using supercritical CO2 at a modest temperature (60°C) and pressure (35 MPa) with little reduction in the oil yield. There were significant reductions in mercury (85 to 100%), cadmium (97 to 100%), and lead (100%) content of the fish oil extracted using the supercritical fluid extraction method. The fish oil extracted using conventional methods contained toxic elements at levels much higher than the accepted limits of 0.1 μg/g.

Acipenser sturio fish oil, rich in ω-3 PUFAs, offers potential for functional foods but is prone to oxidative degradation. This study investigates enhancing antioxidant and emulsifying properties of the oil by modifying Acipenser sturgeon protein (ASP) using metal-phenolic networks (MPNs). ASP was coated with EGCG (epigallocatechin-3-gallate) and Ca, forming ASP-EGCG-Ca complexes (AECas) used as emulsifiers.

Introduction: Immune dysregulation and chronic inflammation have been hypothesized as potential pathways in metabolic syndrome and schizophrenia. Anti-inflammatory diets have the potential not only to treat metabolic syndrome but also to reduce the symptom burden in schizophrenia. The aim of this systematic review was to investigate the role of anti-inflammatory diets and vitamin supplementation in the management of metabolic syndrome and in symptom remission in people with schizophrenia.

Background: Observational studies propose associations between dietary factors and multiple sclerosis (MS). However, the causal nature of these relationships remains unclear. This study aims to determine whether nutritional factors causally influence MS risk through Mendelian randomization (MR) analysis.

The objective of this research is to develop a natural macromolecules-based smart double-layer film using carboxymethyl cellulose (CMC) film containing pomegranate peel anthocyanins (PPA) and cellulose acetate nanofibers (CANFs) with Artemisia sieberi Besser essential oil-loaded nanostructured lipid carriers (ABNLCs). Based on the performance as a color indicator, and other studied properties, the CMC/PPA 8 % film was selected as the optimized film. The double-layer film was constructed by electrospinning the CANFs containing ABNLCs on the optimized CMC film.
