Summary: Beer antioxidants mainly come from malts, and the phenolic antioxidant content and types in Pale Ale beers are influenced by the percentage of dark malt used. Dealcoholization by osmotic distillation has a weak impact on the phenolic fraction, with the content and antioxidant activity of phenolic compounds in beers primarily influenced by the type of malt used.

Summary: For the first time, this study provides a comprehensive characterization and quantification of phenolic compounds in raw and heat-treated northern red oak seeds using UHPLC-DAD-ESI-HRMS/MS. A total of 42 phenolic compounds belonging to five different groups were identified, with significant variability in composition observed among different treatment conditions. Roasting led to a reduction in total phenolic content, ellagitannins, gallotannins, and phenolic glycosides, but an increase in HBA and EA derivatives. Among the roasted samples, the highest total phenolics content was found at 185 degrees C for 25 minutes, while the lowest amounts were observed at 135 degrees C for 80 minutes.

Summary: This study investigated the antioxidant activity and phenolic composition changes in coffee beans from different geographic origins and roasting degrees. The results showed that roasting degree had minimal impact on antioxidant activity and total phenolic content, but affected the levels of different phenolic compounds. Roasting could enhance the formation of purpurogallin and other phenolic compounds, compensating for the decrease in antioxidant activity due to the breakdown of chlorogenic acid.

Summary: This study aimed to investigate the yield, quality, metabolic responses, and potential toxicity of Cucumis sativus grown in juglone-containing soils. It was found that a concentration of 100 mu M of juglone or the same concentration of walnut leaf extract does not affect the yield of C. sativus, while a concentration of 1 mM of juglone strongly affects it. Juglone itself was found only in the roots of C. sativus, but not in the leaves or fruits, making C. sativus fruits considered safe for cultivation in juglone-containing soils.

Summary: This study investigated the influence of three sweet cherry cultivars grafted on six rootstocks on the phenolic profile of the fruits. A total of 54 phenolic compounds were identified, with anthocyanins and hydroxycinnamic acids being the most abundant. 'Kordia' had the highest phenolic content among the cultivars. The choice of rootstock also had a significant impact on the phenolic content, with 'Colt' and 'Gisela 5' promoting the highest values in 'Kordia' and 'Carmen', and 'Oblacinska' and 'M x M 14' inducing the highest values in 'Regina'. The study highlights the importance of cultivar and rootstock selection for improving the phenolic content and nutritional value of sweet cherry fruits.

Summary: This study analyzed the changes in sugar content, organic acids, phenolic compounds, and selected enzyme activities in the anthocyanin pathway in NIGRA (Sambucus nigra var. nigra-black fruits) and VIRIDIS (S. nigra var. viridis-green fruits) fruits at four stages of ripening. The results showed that glucose and fructose content in green fruits were higher than in colored fruits, and sugar content increased significantly until the third developmental stage. NIGRA berries had a high content of anthocyanins and flavonols, while flavonols were the major phenolic group in VIRIDIS fruits. NIGRA fruits showed strong activation of the late anthocyanin pathway, while VIRIDIS fruits lacked anthocyanins and only had one flavanol.

Summary: The study investigated the use of bioprocessed wholegrain spelt flour as a partial substitute for white wheat flour in bread recipes. The addition of 1% and pasteurised 5% germinated + enzymatic treated spelt flour significantly improved the bread's specific volume, but not its texture and sensory evaluation. Increasing the percentage of bioprocessed spelt flour led to a darker bread color and decreased quality. Breads with 2.5% and 5% germinated + fermented spelt flour had the most acceptable characteristics and improved antioxidant content.

Summary: The study aimed to investigate whether replacing wheat flour with bioprocessed spelt flour enhances the bioaccessibility of antioxidants in bread. The results demonstrated that the type and amount of bioprocessed spelt flour significantly influenced the extractable and bound total phenolic content, individual phenolics, antioxidant activity, and bioaccessibility after in vitro digestion. While certain phenolic acids decreased after digestion, others increased. Notably, the digested bread made with 5% germinated + fermented spelt flour contained significantly higher levels of trans-ferulic acid compared to the control bread. Overall, incorporating germinated and fermented or enzymatically treated spelt flour in white bread recipes could be a promising way to offer nutritionally valuable foods to consumers.

Summary: The effects of salicylic acid (SA) and methyl salicylic acid (MeSA) on apple fruit infection with Monilinia laxa were investigated. Curative use of SA and MeSA slowed the infection, while preventive use was generally unsuccessful. Analysis revealed that infected apple peels had higher content of phenolic compounds, and curative treatment further increased the content in healthy tissues. The results suggest that salicylates increase phenolic compounds and curative use is more effective in infection control.

Summary: This study aimed to assess the impact of two agrotechnical factors (floor management and nitrogen dose) on the yield and primary and secondary metabolites in 'Sampion' apple fruit. Living mulch did not decrease yield compared to herbicide fallow. Apples were found to contain a rich composition of phenolic and volatile organic compounds, which varied with the evaluated factors and weather conditions. Precipitation deficit and high summer temperatures hindered fruit growth and development, resulting in a higher content of phenolic compounds in the fruit flesh from trees in herbicide fallow. Living mulch, acting as a regulator of nitrogen availability to trees, stimulated anthocyanin synthesis, which was enhanced by low average temperatures at harvest time, leading to extensive fruit skin red blush.

Summary: This study investigated the differences in the distribution of primary and secondary metabolites in four strawberry cultivars. Results showed that the outer part of the fruit had lower pH, higher organic acid content, and lower glucose and fructose content. Differences were also observed in the total phenolic and anthocyanin contents, which were always higher in the outer part. The study emphasizes the need for proper mixing of samples before extractions to obtain representative results.

Summary: A non-destructive method using a DA-meter to measure chlorophyll absorbance (I-AD) has been used to assess blueberry fruit maturity directly on the plant. This study examined fruit quality parameters, chemical composition, and gene expression at different maturity stages, and found significant changes in all observed parameters during ripening, with high correlation to I-AD values. Peel lightness, chroma, fruit firmness, and organic acids decreased, while sugars, sugar/organic acid ratio, total phenolics, and relative expression of ANS increased during ripening.

Summary: The present study compares traditional fruit processing methods on medlar fruits and their effects on sugar content, organic acids, and phenolic composition. It aims to determine suitable processing methods for technologically mature yet inedible medlar fruits while maintaining their good chemical quality. Analysis shows that fructose and glucose are the major sugars in medlars, while malic acid and quinic acid are the most abundant organic acids. A total of 38 phenolic compounds were identified, with phenolic acids and flavanols predominating. Different fruit treatments resulted in variations in metabolite content, with heated and edible fruits showing lower levels of fructose and sorbitol. Edible fruits had lower content of organic acids, flavanols, and phenolic acids compared to technologically ripe fruits. Heating the fruits increased total phenolic compounds. Exposure to hoarfrost minimally affected the chemical quality of medlar fruits. Processing medlar fruit with hoarfrost remains the most suitable method of fruit bletting.
