Our paper seeks to assess the impact of information and advertisement on consumers' preference for wines in special occasions (Christmas) in Catalonia (Spain). We apply the Choice Experiments method to study the relative importance of attributes that describe consumers' decision to purchase wine by using the Heteroskedastic Extreme Value (HEV) model. Data were obtained from two questionnaires applied to a pre and post spot samples formed by 299 and 400 individuals, respectively. Results suggest that the proposed spot does not affect the ranking of the preferred attributes, nevertheless this preference is heterogeneous. After advertising preferences scores have revealed significant differences. The relative importance of the "Catalan" wine has increased compared to the "Spanish" wine. The most preferred product is a Catalan wine made from the "Cabernet Sauvignon" variety. Wines that have been previously tasted by the consumer seem to be preferred over recommended or prestigious wines. However, advertising increases the relative importance of prestigious wines.

This work assessed the efficiency and sustainability of ultrasound-assisted extraction (UAE) of anthocyanins from grape pomace using bio-based solvents: Ethanol, Isopropanol, Propylene-glycol, and Ethylene-glycol at different concentrations (50 and 100 % v/v) and temperatures (25 °C and 50 °C). Higher ultrasonic intensities (UI) were obtained at 50 °C and 50 % v/v by decreasing solvents viscosities. Under these conditions, anthocyanin extractions were performed with different combinations of solvent to liquid ratio (SLR) at 1:10 and 1:50 g/mL, and UI (3.

Unlabelled: Recent epidemiological studies have suggested a positive association between ultra-processed food consumption and breast cancer risk, although some studies also reported no association. Furthermore, the evidence regarding the associations between intake of food with lower degrees of processing and breast cancer risk is limited. Thus, we investigated the associations between dietary intake by degree of food processing and breast cancer risk, overall and by breast cancer subtypes in the European Prospective Investigation into Cancer and Nutrition (EPIC) study.

A major concern for wineries is haze formation in white wines due to protein instability. Despite its prevalent use, the conventional bentonite method has shortcomings, including potential alteration of color and aroma, slow processing times, and notable wine wastage. Zirconium oxide (ZrO) effectively removes proteins without affecting wine characteristics.

Wines covered by PDO or PGI quality labels have specific sensory characteristics. According to EU regulations, product characteristics (including the sensory description) must be defined in the PDO technical specification and should be verified for their compliance. There exist internationally harmonized quantitative descriptive sensory methods applied to products such as virgin olive oil, with well-defined attributes described in the method itself.
