Summary: This study aimed to establish a rapid determination method for quality detection of edible oils based on quantitatively analyzing palmitic acid, stearic acid, arachidic acid, and behenic acid. The support vector machine model with standard normal variate pretreatment showed the best predictive performance for the four fatty acids. Effective wavelengths selected by the successive projections algorithm were useful for establishing simplified prediction models, proving that Vis-NIR spectroscopy combined with multivariate methods can provide a rapid and accurate approach for fatty acids detection of edible oils.

Summary: During the production, processing, transportation, and storage of edible oils, the oils come into contact with plastic products, leading to the migration of harmful plasticizers. This review provides a comprehensive overview of the sample preparation methods and detection techniques used for determining phthalic acid ester (PAE) plasticizers in edible oils since 2010. The focus is on the combination of sample preparation methods for edible oils with separation-based analytical techniques, such as gas chromatography (GC) and liquid chromatography (LC) with different detectors. The advantages, disadvantages, limitations, and future developments of these techniques are also discussed.

Summary: This study conducted an umbrella review to investigate the nutritional and bioactive components of commonly consumed edible oils and fats, finding strong evidence supporting the beneficial effects of high mono- and polyunsaturated fatty acid compositions, total biophenol content, and phytosterols on high-burden chronic diseases. However, insufficient evidence was found for the impact of squalene. Future dietary guidelines should consider a more comprehensive approach to evaluating edible oils beyond saturated fatty acid content.

Summary: Palmitoylethanolamide (PEA) can gel edible oils at low concentrations, forming elastic gels. The study reveals that PEA forms lamellar solid aggregates with widths of several tens of micrometers in the gels. Upon heating, the sample undergoes a gel-to-sol transition and the melting of the solid particles.

Summary: This study explored the effects of germination pretreatment on the properties and antioxidant activity of flaxseed oil. Results showed that germination increased the unsaturated fatty acid content and antioxidant activity of the oil. Alpha-tocopherol, stigmasterol, pigments, and total phenols also increased significantly with germination. The longer the germination time, the higher the levels of these compounds, indicating improved lipid concomitants and antioxidant capacity of flaxseed oil.

Summary: This study aimed to investigate the changes in physicochemical characteristics and lipid concomitant of rapeseed oil during germination. It was found that germination led to a decrease in acid value and peroxide value, while increasing the content of alpha-tocopherol, phytosterol, carotenoid, and unsaturated fatty acids. These changes improved the nutritional value and edible quality of the oil. Among these components, alpha-tocopherol could be used as a reference marker to determine the germination stage and estimate the nutritional value of rapeseed oil.

Summary: Edible oils are important for human life, providing energy and essential fatty acids. However, they are susceptible to oxidation through various mechanisms, resulting in the deterioration of essential nutrients and the production of toxic substances. Lipid concomitants, a large class of biologically active substances in edible oils, have shown remarkable antioxidant properties and can improve the quality of edible oils in different ways. This review provides an overview of the antioxidant properties of polar, non-polar, and amphiphilic lipid concomitants in edible oils, as well as the interactions and probable mechanisms. It can serve as a theoretical basis and practical reference for food industry practitioners and researchers to understand the variations in the quality of edible oils.

Summary: The study showed that increasing flaxseed gum concentration can effectively decrease the brittleness of flaxseed oleogels, thereby altering their physical properties, including textural parameters, rheological properties, and thermal properties. Flaxseed oleogels exhibit solid-like characteristics, with the elastic modulus reaching a maximum at a certain concentration and decreasing beyond that. The research indicated that flaxseed gum does not negatively affect the crystal forms of flaxseed oleogels.

Summary: This study investigates the effect of water content on the properties and structure of walnut oleogels. Results show that with increased water content, the hardness of the oleogel increases and the oil loss rate decreases. Microstructure observation reveals that an increase in water content leads to an increase in crystal size and quantity.
