Summary: Classical methods for assessing the quality of food grains are either destructive or time-consuming, calling for an alternative approach. Spectroscopic techniques, such as FT-IR, NIR, and Raman spectroscopy, have been extensively studied for efficient determination of grain quality. This review focuses on the working principles and recent applications of these techniques in the grain industry, including quality discrimination, adulterant detection, process optimization, and production monitoring, while also highlighting challenges, limitations, advantages, and future trends.

Summary: The aim of this study was to evaluate the usefulness of emission-excitation matrices for honey authentication and adulteration detection. Four types of authentic honeys and samples adulterated with different adulteration agents were analysed. The unique emission-excitation spectra of each honey type and adulteration agent can be used for classification according to botanical origin and detection of adulteration. The SVM proved to separate the authentic honeys from the adulterated ones better than PLS-DA.

Summary: A new method combining data fusion and chemometrics was established to detect peanut oil adulteration based on fatty acid data. Linear discrimination analysis and support vector machine classification were used for identification, while principal component regression, partial least squares, and support vector machine regression were used for predicting adulterant contents. Results showed that the SVC-based model had better identification capability and the SVR-based adulteration model was significantly better than the PCR- and PLS-based ones. Therefore, the method of data fusion and chemometrics is feasible and provides theoretical foundation and technical support for the safety and quality detection of edible oils.

Summary: This study developed a method based on synchronous fluorescence combined with chemometric tools to classify vodka samples, achieving high accuracy in distinguishing authentic from counterfeit samples. Discriminant analysis and support vector machine were successful in accurately classifying the samples, while k-nearest neighbor was not effective. Ultimately, only SVM with radial base function was able to correctly classify all brands of vodka samples using synchronous fluorescence spectroscopy.

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.
