The production and commercialization of Brazilian grape juice is increasing annually, mainly due to its typicality, quality, and nutritional value. The present research was carried out in view of the great significance of Brazilian grape juice for the grape and wine industry. The purpose of this study, therefore, was to assess its composition as well as the discrimination between grape juice and other beverages. Twenty four samples of whole, sweetened, and reprocessed grape juices, grape nectar, and grape beverage were evaluated. Classical variables were analyzed by means of physicochemical methods; tartaric and malic acids, by HPLC; methanol, by gas chromatography; minerals, by atomic absorption spectrophotometry. These products were discriminated by the Principal Component Analysis (PCA). Results show that whole and sweetened grape juices were discriminated from other grape products because they featured higher values of total soluble solids, tartaric and malic acids, most minerals, phenolic compounds, and K/Na ratio, whereas grape nectar and grape beverage presented higher values of ºBrix/titratable acidity ratio. Reprocessed juice was discriminated due to its higher concentrations of Li and Na and lower hue. |

Pedotransfer functions are methods proposed with the objective of obtaining indirect information, with greater speed and ease to estimate various soil attributes. Thus, the objective of this work was to generate and obtain pedotransfer functions (PTFs) to predict the moisture retained at specific potentials in a Planosol under integration crop-livestock-forest system in the Agreste of Paraíba, three years after implementing the system. The research was conducted in an area located at the Experimental Station of the Paraíba Company of Research, Rural Extension and Land Regularization - EMPAER, in the district of Alagoinha, PB. The experimental design utilized was that of randomized blocks with 5 integration systems and 4 repetitions. The treatments were structured as 1) Gliricídia + Brachiaria decumbens (GS+BD); 2) Mimosa caesalpiniaefolia+ Brachiaria decumbens (MC+BD); Tabebuia alba + Brachiaria decumbens (TA+BD); 4) Zea mays + Brachiaria decumbens (ZM+BD); 5) Brachiaria decumbens (BD). Soil samples with undisturbed structure were collected in three layers (0.00-0.10; 0.10-0.20 and 0.20-0.30 m). Soil water retention was determined in the following matrix potentials: Psi m = -33 e -1,500 kPa. According to the results, it was possible to observe an increase in the available water content in all treatments, as a function of depth, and the soil granulometry was shown to be related to the increase of clay particles in the subsurface. |
