Cherry Tomato Drying: Sun versus Convective Oven
2021
Solar drying and convective oven drying of cherry tomatoes (Solanum lycopersicum) were compared. The changes in the chemical parameters of tomatoes and principal drying parameters were recorded during the drying process. Drying curves were fitted to several mathematical models, and the effects of air temperature during drying were evaluated by multiple regression analyses, comparing to previously reported models. Models for drying conditions indicated a final water content of 30% (semidry products) and 15% (dry products) was achieved, comparing sun-drying and convective oven drying at three different temperatures. After 26–28 h of sun drying, the tomato tissue had reached a moisture content…
Physicochemical properties of vanilla and raspberry aromas microencapsulated in the industrial conditions by spray drying
2018
International audience; Physicochemical properties of powdered vanilla and raspberry complex aromas obtained on industrial conditions by spray drying were investigated. Powders had low water content and activity, promoting long shelf‐life. Aroma retention was lower for vanilla flavors. Raspberry powdered flavors had poorer flowability, lower bulk density, lower particle size, and higher Tg. Additionally, physicochemical properties of powders from various locations of spray dryer (cyclone container/chamber) were compared—powders from the cyclone had higher water content and activity, but the flowability was not affected by collection place. Aromatic substances’ retention of raspberry flavors…
Draining and drying process development of the Tokamak Cooling Water System of ITER
2016
Abstract The ITER Organization (IO) developed a thermal-hydraulic (TH) model of the complex first wall and blanket (FW/BLK) cooling channels to determine gas flow rate and pressure required to effectively blow out the water in the FW/BLK. In addition, US ITER conducted experiments for selected geometries of FW/BLK flow channels to predict the blowout parameters. The analysis indicates that as low as 2 MPa of pressure difference over the blanket modules will ensure substantial evacuation of the water in blankets with just a few percent remaining in the blanket flow channels. A limited validation study indicates that the analysis yields less conservative results to compare against data collec…
Can Dried Fruits Replace Unhealthy Snacking among Millennials? An Empirical Study on Dried Fruit Consumption in Italy
2023
The consumption of dried fruits in place of unhealthy snacks, which are rich in sugars, salt, and fats, could represent a valid option for reaching the daily intake recommended by the WHO for fruits and for encouraging the adoption of a sustainable diet. However, the consumption of dried fruits is lower than that of unhealthy snacks, especially among young people. Therefore, to foster young people’s intentions to consume dried fruits instead of unhealthy snacks, it is important to identify the factors underlying millennials’ consumption intentions. Using a convenience sample of 174 Italian millennials, this paper aimed to understand the factors influencing young people’s i…
