Summary: Improvements in seed yield require shifting plants from conservative to acquisitive syndrome, changing how they allocate and use C and nutrients. Domestication increased biomass production and N acquisition but reduced NUE and MRT in a perennial crop Silphium integrifolium. Higher seed allocation, lower crown allocation, and reduced N storage were observed in improved accessions. HYI had lower MRT due to reduced N storage and N loss through seed production, while LYI had lower MRT due to leaf senescence. HYI litter had lower N concentration and may decrease net N mineralization and soil N availability, while LYI and Wild accession had better internal cycling and faster N-cycles rates.

Summary: In this study, GC-MS analysis was used to analyze the chemical composition of the essential oil from the aerial parts of Jacobaea delphiniifolia collected in Sicily. The results revealed the presence of two main metabolites, 1-undecene (63.57%) and thymol methyl ether (13.65%). This is the first report on the essential oil of this species. Chemotaxonomic considerations were also carried out by comparing the oils of other Jacobaea taxa previously studied.

Summary: This study aimed to evaluate the effects of foliar spraying with humic acid and algal extract alone or in combination with organic fertilizers on the growth, essential oil composition, and quality of two basil varieties under salty soil conditions. The results showed that spraying with 1.5% humic acid and/or 3 mL/L algal extract significantly increased growth characteristics, essential oil yield, and proline content. The response to treatments varied between the two basil varieties.

Summary: The study found that the highest concentration of anthocyanins was obtained in a water-glycerol system with 50% glycerol content. Glycerol can be used as an alternative solvent for extracting anthocyanins, replacing ethanol, and has different optimal concentrations at different extraction temperatures.

Summary: This study optimized the extraction conditions of polyphenols, flavonoids, and chlorophyll from peppermint and common nettle leaves using green chemistry. The use of glycerol-water systems resulted in higher concentrations of these active compounds compared to traditional solvents like water and ethanol. Extraction temperature was found to significantly influence the concentration of the components in the extracts.

Summary: The study found that the mineral content in water significantly affects the extraction of polyphenols and flavonoids from tea leaves, mint leaves, chamomile flowers, sage leaves, and lavender flowers, as well as the antioxidant properties of the brews. Higher mineralization levels in water can reduce antioxidant properties. Brews prepared with deionized water and waters with moderate mineralization levels showed higher concentrations of polyphenols and flavonoids.

Summary: Certain pesticides have been banned in apple and citrus tree cultivations over the past decade. Research shows that washing and peeling can effectively reduce pesticide residues. Comparing apples and citrus fruits from 2012 and 2020, fewer pesticides were found in the edible parts in 2020. The results indicate that conventional washing had no impact on the level of pesticide residues, while apple peeling significantly reduced pesticide levels.

Summary: A study was conducted to investigate the physicochemical properties of blackberry jelly-like desserts made from physically modified starches and chemically modified starches. The viscosity of the desserts increased with decreasing degree of inhibition, regardless of the sweetener used. Thixotropy was observed regardless of the starch modification and sweetener. Kissels made from inhibited starch with xylitol showed the widest hysteresis loop. Retrogradation increased with lower temperature and kissels sweetened with saccharose had low transparency after 7 days of storage, but significantly increased after 28 days. Substitution of saccharose with xylitol only slightly modified the viscosity.

Summary: The aim of this study was to compare the sensory evaluation, nutritional composition, and health-promoting ingredients of raw chocolate with commercial chocolates. The results showed that raw chocolate had lower carbohydrates, higher content of total phenolic compounds, total flavonoids, and total antioxidant activity. However, it received lower ranks in taste due to the lower carbohydrate content. On the other hand, it received the highest marks in external appearance-shape and external appearance-surface condition.

Summary: Mixture design is a statistical tool that optimizes the composition of a mixture using a minimum number of experiments. In this study, a simplex-lattice mixture design method was used to optimize the composition of a mixture of essential oils from basil, citronella, cedarwood, and thyme. The optimized parameter was the antioxidant activity, and the test results showed a synergistic effect between the components of essential oils. The designed mixture with the highest antioxidant activity consisted of 54.4% citronella essential oil, 33.0% thyme essential oil, 9.2% cedarwood essential oil, and 3.4% basil essential oil.

Summary: Plant diseases pose a serious threat to agriculture, the food industry, and human health. Researchers have been exploring natural products to combat plant pathogens and improve food quality, with a new focus on plants as a source of bioactive compounds. This study investigated the antifungal activity of leaf extracts from four lesser-known pseudocereals, namely amaranth species. The results showed that the effectiveness of the extracts varied depending on the amaranth species and fungal strain, with inhibitory effects observed against certain fungi.

Summary: This study aimed to estimate the content of 13 mycotoxins in products from the eastern part of Poland. Mycotoxins were found in 27% of the 92 samples tested, with cereals showing the highest contamination rate at 56%. Deoxynivalenol was the most frequently identified mycotoxin, followed by zearalenone, toxin HT-2, ochratoxin A, and toxin T-2. Exceeding the maximum allowable concentration was observed in two samples.
