This study investigates the chemical composition, nutritional, and biological properties of extracts obtained from berries using different extraction methods and solvents. Hydrodistillation and supercritical fluid extraction with CO allowed us to isolate fruit essential oil (HD) and fixed oil (SFE), respectively. A phenol-enriched extract was obtained using a mild ultrasound-assisted maceration with methanol (UAM).

The method was designed by tailoring certain reaction parameters, such as the sequence of toluene addition, magnetic stirring, the type of reaction solvent, and the calcination conditions. Analysis of the specific surface area and porosity was carried out via N physisorption, whereas the morphological features of the solids were investigated via transmission electron microscopy.

In a healthy population ( = 231 participants), using bivariate correlations and multivariate linear regression analyses, significant sex differences emerged in quinine bitterness perception, with women showing a higher bitter taste intensity rating than men. Among all participants, 40 subjects (subpopulation) were randomly selected for the evaluation of sex differences in Mirtamaro gustatory and olfactory perception using a hedonic Likert-type scale.

Here, the impact of different ageing conditions on the evolution of the surface properties of propyl- and 3-aminopropylphosphonic acid grafted mesoporous TiO over a period of 2 years is reported, using solid-state P and C NMR, ToF-SIMS and EPR as main techniques. In humid conditions under ambient light exposure, PA grafted TiO surfaces initiate and facilitate photo-induced oxidative reactions, resulting in the formation of phosphate species and degradation of the grafted organic group with a loss of carbon content ranging from 40 to 60 wt %.

Due to health risks related to salt over consumption, considerable interest is devoted to strategies to reduce dietary salt intake. In this work we evaluated the sensory dimensions of sea salts flavored with Mediterranean aromatic plants with the aim to confirm the role of herbs/spices in the enhancement of salty perception and to validate the use of flavored salts as a strategy to reduce salt intake.

In this context, the excess thermodynamic properties of these mixtures, specifically the excess molar enthalpies and volumes ( and ), have been extensively measured. Butanol isomer + di--butyl ether (DBE) mixtures received significant attention because of interesting differences in their , changing from negative (1- and isobutanol) to positive (2- and -butanol) with increasing alkyl group branching.
