Abstract: Total antioxidant activity (TAA), total phenolic compounds (TPC), and physicochemical characteristics of ready-to-drink orange juice and nectar from the most consumed brands available in Brazil were evaluated. TPC ranged from 18.7 to 54.2 mg of gallic acid/100 mL, and TAA varied from 57.88 to 349.32 ?mol TEAC/100 mL ready-to-drink orange juice and nectar. The ascorbic acid content was the only physicochemical parameter that showed strong variation among packages and brands. Correlation of TPC with TAA showed that the higher the level of TPC the higher the TAA. Correlation of ascorbic acid content with TAA is higher for ready-to-drink orange juice than nectar. The same was found for the correlation of ascorbic acid content with TPC. The results con?rm the contribution of the TPC to TAA. |

Anthropogenic disturbances directly influence environmental processes and increase the concentration of carbon (C) in the atmosphere. Here, we compare the differences in the seasonality of the balance of carbon, energy, and radiation, as well as seek to identify the interrelationships between these environmental variables and their impact on the growth of Opuntia cactus. Data were acquired from an eddy covariance flux tower over a cactus crop agroecosystem (2019–2021) in the Brazilian semi-arid region. In addition, we use plant growth rates, carbon and nutrient stocks, evapotranspiration (ET) and water use efficiency (WUE), and radiation (RUE). We show that the closure of the surface energy balance was 71%, although there are minimal fluxes of available energy lost (29%) by unquantified processes. At all seasons, the highest net ecosystem CO2 exchange (NEE) rate was between 11:00–13:00 (�� 5.75 μmol m�� 2 s�� 1). During the dry and wet-dry season, there was the lowest daily gross primary productivity (GPP) (2.5 μmol m�� 2 s�� 1) and net radiation—Rn (217.97 W m�� 2). Ecosystem respiration was more expressive during the wet season (2.41 μmol m�� 2 s�� 1), and maximum diurnal value of 2.65 μmol m�� 2 s�� 1. Furthermore, the latent heat flux was higher during the wet season (114.68 W m�� 2) and lowered in the dry season (9.39 W m�� 2). The net assimilation rate showed higher values during the dry-wet transition. The dry season presented higher nutrient use efficiency and WUE (14.77 g m�� 2 mm�� 1). The highest ET occurred during the wet season (227 mm), and RUE was 81.48% higher than in the dry season. Overall, the cactus was a potential C sink during the three years of assessment (NEE: �� 377 g C m�� 2 year�� 1; GPP: 881 g C m�� 2 year�� 1). The results help us to understand that most of the Rn energy is used in the sensible heat flux (58% ratio).
