Summary: Nowadays, developing suitable strategies for managing and adding value to agri-food products is a significant global challenge. This study aimed to explore a valorization strategy for low-grade varieties of date fruit by extracting polyphenolic compounds and studying their health-promoting bioactive properties. The extracts were analyzed for their phenolic contents, antioxidant, anti-inflammatory, anti-hemolytic, and enzyme inhibitory activities during simulated gastrointestinal digestion. The results showed that low-quality dates can be a potential source of bioactive polyphenols with nutraceutical properties.

Summary: Various factors, including apple variety, maturity, farming and storage conditions, and fermentation method, can influence the polyphenol content and antioxidant capacity of ciders, leading to differences in values among ciders from different origins. This study aimed to characterize Spanish ciders in terms of their polyphenol content and antioxidant capacity, and determine whether these properties change after digestion. The Basque Country ciders showed higher levels of polyphenols and antioxidant capacity compared to ciders from other regions, and the in vitro digestion process resulted in a loss of phenolic compounds.

Summary: Crude extracts from raw and roasted Georgia pecans were digested in vitro, and the digested and undigested extracts were separated into low- and high-molecular-weight fractions. The LMW fraction contained primarily flavan-3-ols and ellagic acid derivatives, while the HMW fraction contained procyanidins with different degrees of polymerization. Following digestion, there was a loss in phenolics and an increase in dimers in the LMW fraction, and a decrease in higher oligomeric procyanidins in the HMW fraction. The loss of phenolics after digestion was reflected in reduced total phenolics content and antioxidant capacity.

Summary: Alzheimer's Disease (AD) is a major cause of global dementia cases, affecting around 50 million people worldwide. The leaves of olive trees contain bioactive compounds such as oleuropein (OLE) and hydroxytyrosol (HT), which have shown medicinal properties in fighting AD. Olive leaf (OL), OLE, and HT can reduce amyloid-beta and neurofibrillary tangles formation, and OL has exhibited high cholinergic inhibitory activity. These compounds may also decrease neuroinflammation and oxidative stress, potentially promoting autophagy and restoring loss of proteostasis in AD models. Therefore, olive phytochemicals hold promise as an adjuvant in AD treatment.

Summary: This study investigated the chemosensitizing effects of Manuka honey against 5-Fluorouracil in colonspheres enriched with cancer stem cells (CSCs). The results showed that combining Manuka honey with 5-Fluorouracil decreased the gene expression of ABC sub-family G member 2 and thymidylate synthase, which are associated with drug resistance and DNA synthesis respectively. Manuka honey also regulated the Wnt/β-catenin, Hedgehog and Notch pathways, reducing the self-renewal ability of CSCs. This preliminary study opens new possibilities for the combination of natural compounds and pharmaceuticals to enhance efficacy or reduce adverse effects.

Summary: An efficient, sensitive, and convenient magnetic solid-phase extraction method combined with ultra-high performance liquid chromatography-tandem mass spectrometry (MSPE-UHPLC-MS/MS) was developed for the simultaneous determination of 19 succinate dehydrogenase inhibitor fungicide residues in six different food matrices. The tetraethylenepentamine magnetic graphene oxide nanocomposite demonstrated good dispersibility, large specific surface area, and large pore volume, making it an ideal adsorbent for succinate dehydrogenase inhibitor pretreatment. The MSPE-UHPLC-MS/MS method showed linear correlation and a low limit of quantification, with a recovery range of 71.2%-119.4% for succinate dehydrogenase inhibitor fungicides. This simple, rapid, and efficient MSPE method is an ideal alternative to sample pretreatment for the determination of trace succinate dehydrogenase inhibitor fungicides in complex matrices.

Summary: In recent decades, plants have been recognized for their potential to provide molecules beneficial for health. The Camellia japonica in Galicia, Spain is an example of a plant that has been underutilized and only studied for its composition. However, our study reveals that Camellia japonica has high nutritional value with carbohydrates as the most abundant macronutrients, moderate protein content, and high levels of polyunsaturated fatty acids. It also has potential for biofuel production and contains a high concentration of bioactive compounds, making it suitable for food formulations.

Summary: Polyhydroxy flavonols are easily degraded during thermal processing. This study used UPLC-Q-tof-MS/MS to investigate the stability of dietary polyhydroxy flavonols, including myricetin, kaempferol, galangin, fisetin, myricitrin, quercitrin, and rutin, in boiling water. The degradation of flavonols mainly resulted from the opening of the heterocyclic ring C to form simpler aromatic compounds. The degradation products included 1,3,5-benzenetriol, 3,4,5-trihydroxybenzoic acid, 2,4,6-trihydroxybenzoic acid, and 2,4,6-trihydroxybenzaldehyde, among others. The presence of glycosides in myricitrin slightly affected its stability, while the glycosides in rutin and quercitrin significantly improved their stability in water. During boiling, flavonols underwent various chemical reactions, such as hydroxylation, dehydroxylation, deglycosidation, deprotonation, and C-ring cleavage.

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.
