Avaliação dos parâmetros de secagem da polpa de graviola em pó obtida por secagem em spray dryer Evaluation of the drying parameters of soursop pulp powder obtained by drying in a spray dryer ResumoA polpa de graviola é um produto amplamente consumido no Brasil e sua desidratação pelo processo spray dryer é alternativa relevante para aproveitamento do excedente de produção. Dentro deste contexto, este trabalho teve como objetivo estabelecer a melhor condição operacional de secagem em spray dryer, visando a obtenção de polpa de graviola em pó por meio do planejamento composto central rotacional, tendo a concentração de maltodextrina e a temperatura do ar de secagem como variáveis independentes. Verificaram-se os efeitos negativos lineares e quadráticos significativos (p < 0,05) da concentração de maltodextrina e da temperatura do ar de secagem sobre a umidade da polpa de graviola em pó. Apesar de o modelo não se ajustar aos parâmetros de higroscopicidade e rendimento, foi possível, através do teste de médias, estabelecer as condições de processo. Considerando-se o uso de baixas temperaturas e menores concentrações de maltodextrina, recomenda-se o emprego de 169 °C como temperatura de secagem e 17% (m/m) de maltodextrina como adjuvante de secagem. O uso de tais condições acarreta um produto com baixos teores de umidade e atividade de água, classificado como ligeiramente higroscópico, suscetível ao caking, e que apresenta microestruturas com formato esférico de tamanhos variados e de superfície lisa e uniforme. Palavras-chave: AbstractSoursop pulp is a widely consumed product in Brazil and its dehydration by spray drying has been shown to be a relevant alternative for the exploitation of surplus production. Thus the objective of this research was to establish the best operational conditions to dry soursop pulp in a spray dryer to obtain the powder, using a central composite rotational design (CCRD), the independent variables being the maltodextrin concentration and the drying air temperature. Significant negative linear and quadratic effects (p < 0.05) were found for the maltodextrin concentration and drying air temperature on the moisture content of the powdered soursop pulp. Although the model did not adjust to the hygroscopicity and yield parameters, the process conditions could be established using the means test. Considering the use of low temperatures and lower maltodextrin concentrations, the use of a drying temperature of 169 °C and 17% (w/w) of maltodextrin as the drying aid was recommended. The use of such conditions resulted in a product with low moisture content and water activity, classified as slightly hygroscopic, caking sensitive and that presents a microstructure with spherical shape, different sizes and smooth and uniform surface.

“…Among the soursops exploited in Brazil, the cultivar 'Morada Nova' has stood out due to its easy adaptation to the most diverse types of soil and for being able to produce more than 40 kg of pulp per year. Currently, the Northeast region in Brazil stands out as the largest producer of this fruit crop, especially the states of Bahia, Alagoas, Ceará, Paraíba and Pernambuco (São José et al, 2014;Almeida et al, 2015). This region has scarce rainfall and high evaporation rates, naturally causing a water deficit which limits the growth and production of crops under natural conditions, i.e., rational agricultural exploitation is only possible using irrigation; however, the waters available for irrigation in these regions are not always of good quality, causing the use of saline waters to become a reality, characterizing a problem that affects the economy of the region, the society and the environment (Medeiros et al, 2012;Nascimento et al, 2017).…”

Effects of saline water and exogenous application of hydrogen peroxide (H2O2) on Soursop (Annona muricata L.) at vegetative stage

Soursop is a fruit of great socioeconomic importance for the northeastern region of Brazil. However, the quantitative and qualitative limitation of the water resources of this region has reduced its production. The objective of this study was to evaluate the growth of ‘Morada Nova’ soursop plants irrigated with saline water and subjected to exogenous application of hydrogen peroxide through seed immersion and foliar spray. The study was conducted in plastic pots adapted as lysimeters, using a eutrophic Regolithic Neosol with sandy loam texture under greenhouse conditions. Treatments were distributed in randomized blocks, in a 4 x 4 factorial arrangement, corresponding to four levels of irrigation water electrical conductivity – ECw (0.7; 1.7; 2.7 and 3.7 dS m-1) and four concentrations of hydrogen peroxide – H2O2 (0, 25, 50 and 75 µM), with three replicates and one plant per plot. Foliar applications of H2O2 began 15 days after transplanting (DAT) and were carried out every 15 days at 17:00 h, after the sunset, by manually spraying the H2O2 solutions with a sprayer in such a way to completely wet the leaves (spraying the abaxial and adaxial faces). Treatment effects were evaluated based on plant height (PH), stem diameter (SD), number of leaves (NL) and leaf area (LA) at 60 and 90 DAT, and dry phytomass of leaves (LDP), stem (SDP), roots (RDP) and total (TDP) and leaf succulence (LS) at 90 DAT. Irrigation using water with estimated ECw of 1.55 dS m-1 caused acceptable mean reduction of 10% in soursop growth. Increasing concentrations of hydrogen peroxide did not attenuate the effects of salinity on plant height and leaf area during the vegetative stage. Hydrogen peroxide concentration of 20 µM led to higher leaf succulence in soursop plants.

“…Annona squamosa L., commonly known as sugar apple or sweetsop, is one of the most widely grown members of the Annonaceae family in the world. In Brazil, because of its high commercial acceptance, its production is undergoing expansion, with plantations for fresh fruit production almost entirely destined for the internal market (SÃO JOSÉ et al, 2014).…”

Sugar apple (Annona squamosa L.) is one of the most widely grown member of the Annonaceae family in several regions, but there is still a lack of agronomic data regarding the management of its initial growth stages under Cerrado conditions. The aim of the present study was to evaluate the production of Annona squamosa L. seedlings under different environmental conditions achieved by using shade nets (E1: ChromatiNet® Silver 50%; E2: ChromatiNet® red 50%; E3: ChromatiNet® red 35%; E4: ChromatiNet® Silver 35%) in combination with four different substrates (S1: soil + sand + chicken manure; S2: soil + sand + cattle manure; S3: soil + sand + cattle manure + chicken manure; S4: soil + sand + sheep manure). An experiment was set up using a completely randomized design with treatments in a split-plot arrangement, with four replicates and ten plants per experimental unit. Seedling growth parameters and quality indices were evaluated. The tested environments had higher local temperatures relative to the external environment, which had a negative effect on plant growth. Environment E2 resulted in the highest plant height and dry weight, but led to uneven growth among the evaluated plant parts. The substrate with sheep manure (S4) did not benefit seedling production. The best results for seedling growth and quality were obtained with substrates S2 (soil + sand + cattle manure) and S3 (soil + sand + cattle manure + chicken manure), which are therefore promising for Annona squamosa L. seedling production in the Roraima Cerrado.
