Summary: In this study, a method for extraction and determination of thiamine in fresh yeast biomass was developed. The method combines derivatization, chromatographic separation, and fluorescence detection to specifically detect different forms of thiamine. The method showed high sensitivity, excellent instrumental repeatability, and stability of fluorescence signals. Thiamine extraction via beads beating was found to be the most effective method for preserving the biologically active form of thiamine pyrophosphate. Overall, the developed method provides a sensitive, specific, repeatable, and robust approach for detecting vitamin B-1 in fresh yeast biomass.

Summary: Modified forms of the Guggenheim-Anderson-de Boer model (mGAB), Halsey model (mHAL), Henderson model (mHEN) and Oswin model (mOSW) with temperature term were used to describe the sorption isotherm experimental data of pine nuts at different temperatures. Goodness-of-fit indices were examined to evaluate the moisture sorption models, and the mGAB model showed the best performance at individual temperatures. Furthermore, the mHEN and mOSW models were able to differentiate the temperature effect effectively with the lowest AICc values in one-step modeling.

Summary: This study investigated the extraction yield of valuable compounds from brewer's spent grain using pressurized liquid extraction, with a focus on temperature, solvent type, and flow rate. It was found that water and water/ethanol extractions, as well as higher temperatures, favored the extraction of total phenolic compounds, total flavonoid compounds, and antioxidant activity. High extraction yields were achieved with PLE, maintaining reducing sugars and total reducing sugars in the BSG matrix.

Summary: This study investigated the fermentation characteristics of pine needles for the first time and confirmed their potential as plant-derived feed additives. Four types of fermented pine needles were prepared: natural fermentation, Lactobacillus plantarum SK4315 fermentation, Saccharomyces cerevisiae SK3587 fermentation, and co-culture fermentation. The results showed that all pine needle cultures underwent fermentation with changes in viable cell numbers and pH. LPF fermentation inhibited the growth of most pathogens, and this inhibition became stronger with fermentation. TPC was highest in the 48h SCF and LPF samples, ABTS radical scavenging ability and intracellular antioxidant activity were higher in SCF. In summary, all pine needle cultures were successfully fermented, and LPF enhanced antibacterial activity while SCF enhanced antioxidant activity. This study confirmed the potential of fermented pine needles as feed additives, with enhanced biological activity.

Summary: Food supplements made from saffron extracts are popular due to their various bioactive properties, and it is important to standardize these extracts to ensure product quality and safety. The current methods of standardization, which focus on the safranal content, may not provide accurate measurements. This study suggests using crocin isomers and trans-/cis-crocins, as well as the trans-4 GG/picrocrocin ratios, as new criteria for saffron extract standardization. The relative content of these components and their stability over 36 months in a commercial standardized saffron extract were successfully demonstrated.

The results showed discrepancies between declared content and actual content in 65% of the cases, indicating a high susceptibility to adulteration. The multianalytical methodology also identified undeclared additives and the non-declared addition of vegetable sources other than saffron, highlighting the need for comprehensive assessment of SFS quality.

Summary: This study investigates the variations in lipid digestion profiles among individuals of different ages using in vitro digestion models. The findings suggest that adults have a more comprehensive lipid digestion compared to infants, and infants tend to release shorter chain length and more saturated free fatty acids during digestion. Additionally, the particle sizes in the stomach of the elderly were consistently larger. This study enhances our understanding of how lipids with different degrees of unsaturation undergo digestion in diverse age groups.

Summary: This study investigated the acidification of aroma-enhanced black tea during storage. Analysis of non-volatile substances and organic acids using UPLC-Q-TOF/MS and HPLC revealed a decrease in soluble sugars and amino acids, while an increase in organic acids such as oxalic acid, malic acid, and quinic acid. In vitro experiments further demonstrated that the acidification is a result of the decomposition of sugars and amino acids by heating, as well as the oxidation of aromatic aldehydes. Additionally, the study showed that the taste composition of tea infusion is altered, with reduced amino acids, catechins, soluble sugars, and flavonoids. This research provides a theoretical basis for improving the quality of black tea.
