Summary: Ozonation is proposed as an alternative and sustainable method for vine shoots valorization, and it has been found that phenolic-rich fractions can be obtained through this process. The yield, composition, and antioxidant capacity of the fractions were characterized, showing that time and pH have significant effects on the properties of the fractions. Analysis of the FT-IR and TGA spectra confirms the potential of ozonation for obtaining novel phenolic-rich fractions.

Summary: This study investigated the effects of fermentation and dynamic simulated digestion on the biotransformation and antioxidant potential of apple polyphenols. The polyphenol content of fermented apple pulp was significantly higher compared to non-fermented pulp, and the antibacterial activity improved after fermentation. The antioxidant potential of apple pulp also increased after fermentation and digestion. The findings suggest that fermented and digested apple polyphenols have better bioavailability and can be beneficial for the absorption of active substances.

Summary: In this study, optimization of antioxidant compound extraction from apple pomace using ultrasound technology was investigated. Different sonication powers, extraction temperatures, and extraction times were studied to determine their influence on extraction yield and characteristics of the samples. The optimal extraction conditions for maximum phenolic compound extraction were found to be 20 minutes, 90 degrees Celsius, and 50% ultrasound amplitude.

Summary: This study investigated the effects of convective and sun drying on quality parameters of apple, plum, and a blend of apple and plum leathers. The study also compared physical, sensory, and chemical attributes determined by chemical methods with an infrared spectroscopic method. Overall, infrared spectroscopic method was recommended for a robust and fast determination of physico-chemical attributes in fruit leather production.

Summary: This study investigated the extraction of polyphenols from apple peels using ultrasonication in a water carbon dioxide (CO2) system. The research showed that the water CO2 system, with a CO2 concentration of 5.28 mmol/L, was optimal for polyphenol extraction. The use of ultrasonication significantly increased the extraction efficiency for polyphenols and active substances in apple peels.

Summary: Production of virus-free plants is crucial for vegetative propagation. In vitro thermotherapy treatments can effectively eliminate viruses in apple shoots, leading to significantly faster growth in virus-free plants. Rapid assessment of physiological, growth and sanitary state of apple shoots can be performed through chlorophyll content evaluation using SPAD-502 meter.

Summary: A comprehensive study using modern analytical techniques was conducted to investigate the chemical composition of apple fruits from cultivars grown in Western Norway. The study analyzed metals, sugars, organic acids, antioxidant tests, and polyphenol content. The results showed the presence of dominant sugars, organic acids, and metals, as well as the quantification of various polyphenols. These findings provide important data on the quality assessment and differentiation of Norwegian apple samples.

Summary: High-pressure homogenization (HPH) at 100-200 MPa significantly impacted the microbiological quality and oxidoreductase activity of apple juice, leading to tissue disintegration and viscosity reduction. Vitamin C decreased by 62%, while TPC increased by 20% after HPH. Significant correlations were observed between antioxidant activity, TPC, and individual polyphenols.

Summary: In this study, the regulation of the human melatonin biosynthesis-related enzyme HIOMT in alkaline stress in apple plants was investigated. The overexpression of HIOMT under alkaline stress increased the concentration of endogenous melatonin in apple leaves, alleviating plant growth inhibition, enhancing root development, leaf photosynthesis, and antioxidant capacity, and stabilizing cell membrane permeability and ionic balance. Additionally, the transgenic lines also increased the concentrations of organic acids, such as oxalic acid, malic acid, malonic acid, citric acid, and succinic acid, which alleviated high pH stress. These results highlight the critical role of HIOMT overexpression in the alkaline stress tolerance of apple plants.

Summary: The study focused on incorporating black carrot anthocyanins in apple tissue using ethanol pre-treatments and ultrasound-assisted convective drying. The results showed that ethanol pre-treatments and ultrasound application significantly accelerated the drying process and helped retain the nutritional properties of the dried samples by naturally incorporating colorants during pre-treatments.
