Microfiltration of centrifuged açaí pulp was performed using two types of membrane (ceramic and polymeric), each one at two temperatures (25 and 35°C), aiming to evaluate the influence of these parameters on its chemical composition and antioxidant activity. Temperature and membrane material did not significantly influence the bioactive components contents and the antioxidant activity of the two obtained fractions. However, permeate flux was strongly dependent on both factors, reaching the highest mean value (117 l/h m2) with the ceramic membrane at 35°C. Clarified juice, the permeate fraction, contained about 16 mg/100 g of anthocyanins, 138 mg/100 g of total phenolics and 9 umol Trolox/g of antioxidant activity. The retained fraction, with characteristics similar to the original açaí fruit, presented 75 mg/100 g of anthocyanins, 433 mg/100 g of total phenolics and 31 umol Trolox/g of antioxidant activity. Therefore, microfiltration of açaí resulted in two fractions with distinct characteristics, both rich in bioactive components and with potential industrial application. |

Abstract: One factor limiting the achievement of high yields in the soybean crop is weed interference. The level of weed interference can vary according to the specificities of the weed community but also due to the agronomic characteristics of the soybean varieties. The objective of this work was to evaluate the effects of weed interference on soybean varieties of different relative maturity groups (RMG). A field experiment was implemented in a randomized complete block design, in a 3 × 4 factorial scheme, with five replications. The treatments were composed of the varieties BMX Flecha® (RMG 6.6), BMX Power® (RMG 7.3), and BMX Bônus® (RMG 7.9), associated with the following four weed managements: weeding throughout the cycle; weeded up to 20 days after emergence (DAE); weeded after 20 DAE until the end of soybean cycle; not weeded throughout the entire cycle. There was no interaction between the effects of the varieties and the weed management for emergence speed index, plant height, chlorophyll, first pod height insertion, plant population, thousand-grain weight and yield. The initial weed management caused changes in the composition of the weed community. The managements weeded throughout the cycle and weeded up until 20 DAE provided higher levels of chlorophyll and grain yield. The management without weeding during the entire cycle negatively influenced yield components. Late interventions in weed control, regardless of the soybean variety, result in yield losses. |
