Special Issue Information

Dear Colleagues,

In the era of intensive technological development, changes are taking place in all areas of human life, and many of them concern food and nutrition. Modern analytical techniques allow the detection of compounds occurring in extremely small amounts that were impossible to detect before. This not only enhances knowledge of the composition of food products but also enables fast, precise, and accurate control of food brought to market for the first time and sold for years. Major changes are also taking place in the food industry, as, on the one hand, automation has made many technological operations easier to perform, but it has also influenced their course and increasingly reduced the role of man.

We encourage you to share with us in this Special Issue your insights on advances in food analysis and processing in areas of human life and their impact on food quality. It is important to identify in which areas it improves food safety and quality in the broadest sense and when it may cause risks, especially those difficult to predict at the stage of planning and implementing new technologies. It seems interesting to determine the impact of new technological solutions on the chemical composition of food, especially biologically active compounds with documented effects on human health. It is also worth determining whether advances in food analytics increase the reliability of the results obtained and whether the diversity of technical solutions in this area facilitates the comparison of results obtained in different laboratories.

It is also important to establish how consumers perceive advances in food analysis and processing. Do they see the introduction of new food processing technologies as a threat or an improvement in food safety and nutritional value?

Ajwain essential oil and thyme essential oil naturally contain important bioactive compounds. Various researchers have discovered that these compounds contribute biological benefits for living things such as humans and animals. Bioactive compounds found in essential oils, such as terpenes and terpenoids, possess antibacterial and flavouring qualities, making them promising natural preservatives in the food business. This study investigates the effect of essential oil treatment methods on their incorporation into dehydrated beef and its subsequent sensory acceptability. The meat samples underwent hot air blanching and oil treatment with doses of 0.75 mL and 1.5 mL, respectively. Subsequently, the samples were dried at 55 °C for 6 h after each treatment. The identification and quantification of volatile chemicals were performed using headspace solid-phase microextraction and gas chromatography–mass spectrometry. Thymol, γ-terpinene, p-cymene, and β-pinene were the predominant compounds before and after the treatments. The findings revealed that the application of ajwain and thyme essential oil treatments resulted in significant differences in the final concentration of monoterpenes. However, the sensory evaluation indicated that the ajwain and thyme essential oil samples received similar overall ratings. Consequently, ajwain essential oil could be a suitable alternative to thyme in beef jerky. Full article

This study presents a fast, non-invasive method to determine the iodine value (IV) of edible oils using Time Domain Nuclear Magnetic Resonance (TD-NMR) and Magnetic Resonance Imaging (MRI) techniques. The IV, which quantifies the degree of unsaturation in fats and oils, is a key parameter in assessing oil quality and detecting potential adulteration. Different edible oils were used in this study (sunflower, soy, olive, sesame, and linseed). Statistically significant regression models (R2 > 0.92) were established between the IV derived from NMR spectra and the longitudinal (T1) and transverse (T2) relaxation times of the oils, which were obtained from MRI and TD-NMR analyses. The regression models obtained allow for the prediction of the IV from the T1 and T2 relaxation times across a range that includes predominantly mono- and polyunsaturated edible vegetable oils. The TD-NMR approach stands out for its speed (<2 min), lack of sample preparation (including direct analysis within the commercial packaging), and reproducibility, with a variability of only 0.62%. Meanwhile, the MRI technique allows for the simultaneous evaluation of multiple samples in a single acquisition. Together, these features make TD-NMR and MRI effective tools for the rapid and reliable analysis of the IV in edible oils. Full article
