Acta Scientiarum Polonorum : Technologia Alimentaria , 2007,
Abstract: The presented work defines the influence of technological process on chemical composition of peppers. The technological treatments made in this work were: lyophilization and samples evaporation. Evaporation process was conducted in two conditions of temperature and pressure: I – 35°C and 70 mbar, II – 50°C and 400 mbar. The working material consisted of four pepper cultivars, two sweet: ‘King Artur’ and ‘Red Knight’, and two hot: ‘Capel Hot’ and ‘Robustini’. The changes of vitamins C and E, β-carotene, xanthophylls and phenolic compounds were investigated as processing and cultivar factors. Additionally antioxidant activity of phenolic compounds was evaluated by method with DPPH radical. The extracts prepared in conditions I had a significantly higher concentration of vitamin C, E, β-carotene, total phenol and antioxidant properties than the extracts obtained at the higher temperature and under the higher pressure. It was found that extracts obtained from hot fruits had a higher vitamin E and β-carotene contents than from the sweet ones. However, the extracts from sweet varieties were characterized by higher antioxidant properties and phenolic compounds than the ones obtained from hot peppers.

Abstract: The viability of the use of brackish water in the hydroponic cultivation of vegetables cannot dispense with auxiliary techniques such as water mixing and the use of plant densities. In this sense, the objective of the present work was to analyze the growth and production of sweet pepper, cv. All Big, under hydroponic conditions, under different levels of electrical conductivity of the nutrient solution (1.7, 3.7, 5.7, 7.7, 9.7 and 11.7 dS·m-1) in plants spaced every 0.2 m and 0.3 m. These treatments were distributed in a completely randomized experimental design, analyzed in a 6 × 2 factorial scheme, with five replications. The growth variables were evaluated at 60, 75 and 90 days after sowing and the production variables at the time of harvest; however, the results were submitted to analysis of variance, at a 0.05 probability level. The interaction between the electrical conductivity of the nutrient solution and the density of plants influenced the behavior of the growth and production variables of pepper (All Big). It was verified that the pepper plants had better performance of the biometric variables plant height, stem diameter and number of leaves when cultivated every 30 cm. At the time, in the analysis by plant, the production of pepper fruits was more expressive when spacing of 30 cm was adopted, however, in the tube of six meters, when 20 cm of spacing was used, the number of fruits was on average, 26.38% and 16.40% higher than lower density, in the electrical conductivities 1.7 and 11.7 dS·m-1.

Agricultural Sciences (AS) , 2018, DOI: 10.4236/as.2018.98064
Abstract: Water availability is a fundamental condition for sustainable agriculture. However, a satisfactory water condition is not always possible in terms of quantity and quality in certain regions, such as the Brazilian semi-arid region. Thus, the purpose of this extremely important research was to evaluate the growth of cv. All Big with six combinations of wastewater plus saline (WW + SW) and two nutrient solution percentages, in a low-cost hydroponic system. The experiment was carried out in a greenhouse at the Department of Agricultural Engineering at Federal University of Campina Grande. A completely randomized experimental design was used, with treatments arranged in a factorial scheme (6 × 2), with 5 replications, being the treatments composed by the combination of six proportions of wastewater with saline water (50%/50%; 60%/40%; 70%/30%; 80%/20%; 90%/10%; 100% of wastewater) and two nutrient solution concentration (80% and 100%), totalizing 60 experimental units. The biometric variables were analyzed at 55 and 96 days after sowing, namely: plant height (PH), stem diameter (SD), leaf number (LN) and leaf area (LA). The interaction between the concentration of the nutrient solution and the ratio of the saline water with wastewater was influenced in the behavior of peppers (cv. All Big) biometric variables. The nutrient solution prepared at 80% of its normal concentration had better performance in the development of plants when mixed with the proportions of water containing more wastewater. The proportion 30% saline water and 70% wastewater (30/70) with concentration of 80% of the nutrient solution obtained better satisfactory results in the studied biometric variables.

Agricultural Sciences (AS) , 2019, DOI: 10.4236/as.2019.104037
Abstract: The cultivation of goat chili has potentially increased in Chile, due to different varieties of gourmet products made with it; for this reason, new industrial projects are sought to the growing volume to adapt them to the new trends in consumption habits, mainly focused on achieving an attractive meal, a fast preparation and consumption, while nutrients are provided to offer some benefits for human health. The “snacks” products that include the use of fruit satisfactorily respond to these requirements, in addition to providing marketing alternatives to the surplus of fruit exports. For this reason, the present test, consisting of the processing of snacks based on goat chub chili with the addition of tomato and marjoram, was carried out to increase the palatability and the sensorial quality of the final product. The following formulations were used: only chili (T1); chili and tomato (T2); chili, tomato and marjoram (T3). The latter one was characterized by a good flavor and aroma. A large amount of the fruit water content had been removed by drying it with forced hot air. A product without chemical preserves was obtained, with physical and chemical parameters similar to those required by similar foods existing on the market today. In sensorial terms, the formulation to which marjoram was added showed good sensorial and acceptability attributes, highlighting them from the rest of the treatments. The snack color was maintained after the dehydration process, according to panelists.
