Summary: This study characterized the honeys produced by stingless bees Cephalotrigona capitata and Scutellaris Latrelle in the Caatinga and Atlantic Forest biomes in terms of their chemical composition, antioxidant activity, and phenolic, volatile, and sensory profile. The honey labeled as "Mombuca similar to o" showed higher water activity, acidity, sucrose content, and organic acids content, while the honey labeled as "urucu" showed the highest fructose and glucose content. Various phenolic compounds and flavonoids were quantified, with significant amounts of epicatechin gallate, myricetin, quercetin, and procyanidin A2. The honey labeled as "Mombuca similar to o" exhibited the highest antioxidant activity. 133 volatile compounds were identified in the honeys, with terpenes and esters being the most abundant. The honey labeled as "Mombuca similar to o" had a distinct sensory profile characterized by an acid and citrus aroma and flavor, while the honey labeled as "urucu" had a more typical sweet and woody aroma and flavor. The variation in honey composition was attributed to bee species, floral species, and geographic origins.

Summary: Compared to its wild relatives, cultivated tomato has lower levels of constitutive volatiles, reduced morphological and chemical defenses, and increased leaf nutritional quality, which affect its resistance against the specialist herbivore Tuta absoluta. The domestication process has unintentionally compromised certain traits, such as plant defense and nutritional value.

Summary: The research shows that the cation exchange treatment can improve acidity, color, stability, and aromatic compound concentrations in wines, with the most significant effects observed in wines with 20% permeate. Additionally, potassium and magnesium cations decreased during aging, and specific aromatic compounds reached high concentrations, exceeding perception thresholds in all wines, after six months of aging. This suggests that cation exchange resins could be an effective industrial alternative for producing balanced red wines in a changing climate.

Summary: The study revealed that cooking significantly reduced the total concentration of volatiles in both champignon and oyster mushrooms, with the lowest contents found in the oven-cooked samples. Phenolics were found to be more abundant in champignon samples than in oyster samples, with boiling causing a decrease and oven-cooking resulting in an increase in phenolic content.

Summary: This study demonstrated significant effects of substrate culture on volatile compounds in 'Amaou' strawberry, while no significant impact was observed for cultivar 'Yuexin'. 'Amaou' strawberries from soil culture had higher levels of volatiles, including furanones, beta-linalool, trans-Nerolidol, and esters, which are major contributors to strawberry aroma. Strawberry fruit from soil culture also showed higher transcripts related to volatile biosynthesis compared to substrate culture.

Summary: This study investigated the effects of various drying methods on the aroma and phenolic composition, microstructure, and color properties of citrus fruit peels. The results showed that drying increased the content of phenolics and volatiles in the dried samples. Microwave drying (MD) and freeze drying (FD) methods were found to be more effective in preserving the color and phenolic compounds, while MD and convective drying (CD) processes increased the aroma substances.

Summary: This study evaluated the combined effect of microwave-assisted extraction and stem additions on the chemical composition of Bonarda wines. The results showed that stem additions increased tannin content, while microwave-assisted extraction improved phenolic extraction and polymeric pigments formation, enhancing wine color. In addition, the combined strategies increased polysaccharides extraction and modified the volatile profile of wines.

Summary: The impact of Japanese beetles on the quality indicators of Nebbiolo and Erbaluce grapes, specifically their phenolic and volatile composition, was examined. The study revealed that grapes produced by plants attacked by Japanese beetles had higher levels of phenolic compounds compared to healthy plants. Similarly, the volatile composition of the affected grapes was also higher. The plants responded to the beetle attack by increasing the content of certain volatile compounds.

Summary: This study investigated the chemical composition of strawberry (Fragaria x ananassa 'Red Face') flower volatiles and their effects on honey bees and bumblebees. It found that the volatiles of 'Red Face' were different from other strawberry varieties and that certain compounds elicited antennae and behavioral responses in bees. These findings support the idea that strawberry flower volatiles play a role in bee foraging decisions, and can inform bee pollination strategies to improve strawberry fruit quality.

Summary: The study examines the effects of pollen-parent on fruit size and quality in self-pollinated and cross-pollinated fruit of Redlands Joy strawberry plant. The results suggest that these effects are independent of fertilized seeds percentage but are more pronounced when calcium is limited. Additionally, there are temporary increases in size and skin darkness due to cross-pollination during early fruit growth and consistent increases in the final week of fruit development. However, there is little evidence to suggest that self-pollinated and cross-pollinated fruit differ in mineral nutrient accumulation.

Summary: The genetic diversity among grapevine cultivars is low, and breeding for agronomic traits increases the contents of soluble sugars, total phenolics, and anthocyanins in grape juices. The metabolic profiles of the juices accurately reflect the genetic distances between cultivars.
