The state of Mato Grosso has several forest species that are widely used for originating various products that are important to the state's economy. The technological characteristics allow several uses of wood, however, there are species of the same genus that have little studied properties. The objective of this work was to characterize the technological properties of cedar wood (Erisma uncinatum) and white cedar wood (Erisma bicolor). Techniques for anatomical characterization and tests for physical properties tests were employed. Drying test was performed at 100º C, obtaining the drying temperature in different ranges: T1 (5%), T2 (30%) and T3 (30 and 5%) and drying speed: V1 (5%), V2 (30%) and V3 (30 and 5%). It was observed that the cedar species presented larger dimensions for most of the evaluated anatomical elements in relation to the white cedar species. However, the anatomical arrangement for both species was similar at the microscopic level. There were significant differences between the basic densities for the species which influenced the other physical properties, specifically the retractability and drying speed. With the drying program elaborated it was noticed that there was time difference for the wood of the species to reach the moisture content in the range of the saturation point of the fibers, while for 5% of moisture content they kept the same drying time, generating differences in absolute values between species in water loss velocity between 30 and 5% moisture content.

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 of 15%. However, less drying time, about 10–11 h, was needed when starting with an initial moisture content of 92%. The tomato tissue had high ORAC and polyphenol content values after convective oven drying at 60 °C. The dried tomato samples had a satisfactory taste, color and antioxidant values.
