    Abstract: A Pereskia aculeata Miller é uma hortaliça não convencional cujo consumo pode fornecer à dieta substâncias nutritivas e antioxidantes, ambas com teores influenciados pelas condições de cultivo. Foram cultivadas, a partir de sementes, plantas em sombra artificial, em meia sombra e sem sombra. Avaliou-se o crescimento em termos de massa e unidades estruturais e quantificou-se o resíduo mineral, proteínas, lipídeos, fibra em detergente neutro, fenóis e atividade antioxidante. Há influência do sombreamento no crescimento, no teor de nutrientes e metabólitos secundários. As plantas sem sombra apresentaram maior altura, número de folhas, diâmetro do colo, massa seca de caules e folhas e atividade antioxidante. As plantas totalmente sombreadas apresentaram maiores teores de cinzas, lipídeos e proteínas. Para todos os parâmetros avaliados os teores quantificados em folhas foram maiores que em caules.

    Abstract: The purpose of this work was to evaluate the extraction and quantification of total phenolic compounds and the antioxidant activity of two peppers processed by four different methods (in natura, dried, preserved in vinegar and preserved in oil). The extraction efficiency of total phenolics using seven solvents (distilled water, ethanol, 50% ethanol, methanol, 50% methanol, ketone p.a and 50% ketone) were checked. Total phenolic analyzes were performed using the Folin-Ciocalteu and gallic acid method to obtain the standard curve with 650 nm absorbance reading. The antioxidant activity was determined using a spectrophotometric method using the reagent 2,2-diphenyl-1-picryl hydrazyl (DPPH). No significant differences were observed in the two extraction times 6 and 24 h. For samples preserved in vinegar, no significant differences were observed between the solvents used for the extraction. The Capsicum chinense pepper showed the highest amount of phenolic compounds in all treatments when compared to the chili pepper, except when conserved in oil. For the dry pepper, the lowest total phenolic extraction value was obtained with 99.5% ethanol (p.a.) and acetone p.a ACS 99.5% (p.a.), which differed from the peppers preserved in oil. The analysis of the antioxidant activity of Capsicum chinense and Capsicum spp did not present a significant difference (p 〉 0.05) when compared to the dried or vinegar preserved samples. However, the sample of Capsicum chinense pepper in natura presented higher antioxidant activity than the samples conserved in oil. It can be considered from the experimental results that the peppers in this study, especially in fresh and dried form are good sources of natural antioxidants.

    Abstract: Bombons trufados são um tipo especial de chocolate que tem uma textura cremosa e delicada, formada pela mistura de chocolate e creme de leite, conhecida como ganache. A ora-pro-nóbis (OPN), é uma hortaliça não convencional de fácil cultivo, com folhas comestíveis abundantes mesmo durante a seca. A produção do bombom trufado acrescido de folhas secas de ora-pro-nóbis (“tipo farinha”), constitui uma excelente fonte proteica, sendo uma proposta para introduzir e facilitar a aceitação do consumo desta hortaliça em um alimento já consolidado. Assim sendo, objetivou-se avaliar a aceitação sensorial de bombons de chocolate, tipo trufa, com melhores características nutricionais ao acrescentar folhas de ora-pro-nóbis em diferentes proporções. As folhas de OPN foram dessecadas em micro-ondas e trituradas para formação de um pó, o qual foi acrescentado ao chocolate derretido e manipulado. As análises químicas foram executadas com em delineamento experimental inteiramente casualizado, totalizando 35 parcelas experimentais. A análise sensorial foi realizada em escala hedônica de 5 pontos, com 120 provadores não treinados. Pôde-se observar diferença significativa (p 〈 0,01) em todos os parâmetros físico-químicos analisados (umidade, cinzas, fibra bruta, proteína, lipídeo). Independentemente da formulação, pode-se afirmar que a inserção de folhas secas de OPN no bombom resultou em alteração da sua composição e observou-se que as trufas de formulação 10% de OPN somente na casca e 5% na casca e 5% no recheio obtiveram aceitação igual ao bombom trufado sem folhas secas de OPN. Portanto, a utilização da OPN na elaboração de bombons trufados é viável e agrega qualidade nutricional à trufa sem reduzir a aceitabilidade nutricional.

    Abstract: Objective: the aim of this work was to formulate non-fermented mixed fruit drinks, containing Barbados gooseberry leaves in their composition, and to characterize such drinks chemically and sensorially. Six drinks were formulated, combining or not pineapple, lemon, mango, passion fruit, cashew, and melon with fresh Barbados gooseberry leaves. Sugar was added to the drinks for sensory analysis. Methods: chemical characterization was carried out (pH, Brix, total acidity, total solids). Sensory analysis was performed with an untrained panel of 35 tasters for acceptance testing on a 9-point hedonic scale. Statistical analysis used the free software AgroEstat. Results: the results of the chemical analysis showed that the beverages were within the norms, acidic (pH 〈 7), and the highest levels of soluble and total solids were for creamier textures in formulations 1.4 and 5. The overall impression was one of good acceptance by the tasters, as evidenced by an acceptability index (IA%) of 77%. Conclusion: in general, the drinks had excellent acceptability, and can be incorporated into everyday diets, as they are accessible and easy to prepare, bringing new flavors to the food.

    Abstract: Establishing good infant eating habits in childhood is quite important for proper growth and development. The increasing number of mothers who work outside home has made children have their meals in day care centers or schools. In addition, meals have their preparation being replaced by more suitable options, like instant food, lately depriving kids from good eating and nutritional habits. Such kind of food does not contribute to the formation of good eating habits. Thus, vegetables such as the ora-pro-nóbis (unconventional vegetable, known in English language countries as Barbados Goosenberry and cientific name Pereskia aculeata Miller) that have in their leaves proteins, fibers and minerals, like iron, can contribute to improve the childlike feeding. In order to improve the nutritional value of commercial chocolate cake premixes, in natura ora-pro-nóbis leaves were added in at ratios of 0 (standard), 10, 20, 30 and 40% leaf weight per dough weight, which were covered with chocolate kind icing. Moisture, ashes, lipids, proteins, crude fiber and carbohydrate and total caloric content (VCT) were analyzed in the elaborated formulations. The results showed a significant increase in water retention, crude fiber content and decrease in total caloric value (VCT) in the added cakes of ora-pro-nóbis leaves.

    Abstract: Medicinal plants have played an essential role in the development of human culture. Today, the contribution of plants in industries such as fine chemicals, cosmetics, pharmaceuticals, drugs, and industrial raw materials is remarkable. Recent studies have shown that plants have constituents with functional properties that effectively treat and prevent chronic degenerative diseases. Based on the importance of medicinal plants, this study aimed to quantify the total phenolic content and antioxidant activity of 10 medicinal plants. The phenolic content was quantified using the Swain and Hillis method with a Folin-Ciocalteau reagent, while the antioxidant activity was determined using a 2,2-diphenyl-1-picrylhydrazyl (DPPH) reagent. The samples were dried in a circulating air incubator at 60 ºC for 48 h before phenolic extraction. The compounds were extracted with 50% v/v ethanol, 50% v/v acetone, and distilled water. The results of this study showed that 80% of the plants analyzed had similar phenolic contents that were not statistically different, with an average content of 4.864 mg GAE g-1. The antioxidant activity ranged from 30% to 75%. The ability to scavenge free radicals was expressed as the percentage of inhibition of the oxidation of the radical. In addition, no significant differences were observed in the yield obtained from the extraction solvents, 50% v/v ethanol and 50% v/v acetone, used in this study.

    Abstract: The Pereskia aculeata Mill. plant, known in Brazil as Ora-pro-nobis, is a non-conventionalvegetable with high leaf protein content, however studies on the crop system of this leaf vegetableare scarce. Therefore, the objective of the present work was to evaluate the effect of organic compost(OC) rates and irrigation depths (ID) on leaf dry weight (LDW) and leaf protein content (LPC) for P.aculeata plants. The experiment consisted of five OC rates (0, 15%, 30%, 45%, and 60% of thesubstrate volume) and three ID (50%, 75%, and 100% of the reference evapotranspiration - Et0),with four replications. The analysis of variance by the F test (α = 5% and 1%) and the interpretationof the interaction between the factors by response surface demonstrated the increase of ID from 50%to 100% Et0 is more significant for the increasing in LDW than the increases in OC rates. The highestLDW accumulation was found by combining 33% OC in the substrate with ID of 100% Et0. Thelowest LDW resulted from the combination of 60% OC and ID of 50%. The highest LPC was foundwith the use of 52% OC and ID of 69%, and the lowest with the ID of 100% and absence of OC inthe substrate.Keywords: Nutritional supplementation. Waste management. Non-conventional vegetable. Barbadosgooseberry. Ora-pro-nobis.
