Release of bioelements and phenolic compounds from edible mushrooms (Agaricus bisporus, Cantharellus cibarius, and Lentinula edodes) enriched with zinc, selenium, l-phenylalanine, alone and as a mixture was examined using a simulated human gastrointestinal digestion method. Due to the extensive amount of data obtained, in order to interpret them more precisely in the work, the methods of chemometric analysis (Cluster Analysis-CA and Principal Compenent Analysis-PCA) were additionally applied. The results showed mycelium of L. edodes has the best health-promoting properties and addition of mixture to the media increased significantly the synthesis of p-hydroxybenzoic and protocatechuic acid (267 and 16.3 mg/100 g d.w.). After extraction into artificial digestive juices, 97.4 mg/100 g d.w. p-hydroxybenzoic acid and 15.6 mg/100 g d.w. of protocatechuic acid were released. The greatest amounts of Se and Zn were extracted from enriched A. bisporus mycelium (32.3 and 342 mg/100 g d.w., respectively). This study confirmed that mycelium might prevent nutritional deficiencies in the diet through use of functional foods.

Grape marc, a by-product of winemaking, is a rich source of bioactive compounds, yet efficient extraction methods suitable for industrial application remain underexplored. This study presents an integrated, three-stage approach to optimise the extraction of anthocyanins, phenolics, and tannins from Merlot grape marc. In the first stage, 12 solvents were evaluated using conventional solvent extraction, with 50 % ethanol (EtOH) acidified with hydrochloric acid (HCl) achieving the highest anthocyanin recovery after eight extraction cycles (0.

The research intended to explore the control ability of alginate oligosaccharide (AOS) on Penicillium expansum infection in pear fruit by priming response and its mechanism. The results showed that 100 mg L AOS treatment could significantly reduce the incidence of postharvest blue mold and the lesion diameter in pear fruits and maintain their quality. The defense responses induced by AOS treatment alone were relatively mild in pear fruits.

Honey is a valuable natural product with antioxidant properties, and its quality is influenced by various factors, including botanical origin and biofortification. Pine bud extracts, known for their antioxidant capacity, were explored to enhance the properties of acacia and polyflower honey. This study aimed to investigate the effect of pine bud extracts at different maturation stages on the moisture content, dry matter, antioxidant activity, and total phenolic content (TPC) of acacia and polyflower honey.
