Características físicas, reológicas e sensorial de produtos extrusados de misturas de farinha de maracujá e fécula de mandioca

This research had as objective to evaluate the effect of extrusion temperature and screw speed on physical and rheological properties, as well as, the sensory acceptance of cassava and passion fruit snacks produced in single-screw extruder. A central composite design with 11 treatments was used, considering as dependent variables: expansion index (EI), specific volume (SV), water solubility index (WSI), water absorption index (WAI), color (L*, a*, b*) and pasting properties (RVA). The products were flavored and analyzed for global acceptance. The results showed significant effects of temperature and screw speed on the dependent variables. The chocolate flavored snacks obtained good acceptance.

Bioactive compounds of the lipid fractions of agro-industrial waste

This study aimed at evaluating the oils extracted from seeds originating from agro-industrial waste, in order to identify the presence of bioactive compounds. Therefore, determinations of fatty acid profile, triacylglycerols, tocopherol composition, phytosterols, phenolic compounds, total carotenoids, and antioxidant capacity were performed in the oils of grape, guava, melon, passion fruit, pumpkin, soursop, and tomato seeds. Antioxidant capacity analysis was performed by the methods DPPH• , ABTS•+, FRAP, and β-carotene/linoleic acid, besides measure of oxidative stability in the oils. The oils showed to be predominantly unsaturated with high percentage of linoleic essential fatty acid (38.8 to 79.4%), besides presenting significant quantities of tocopherols, phytosterols, and phenolic compounds. Tomato and guava oils showed better results in the antioxidant capacity tests and pumpkin oil had higher induction period in the oxidative stability test (65.3 h). The results obtained in this study collect information that enables the use of new alternative sources of vegetable oils, obtained from agroindustrial waste, which may serve as raw material for food, chemical, and pharmaceutical industries.

Desenvolvimento inicial de maracujazeiros (Passiflora edulis f. flavicarpa, P. edulis f. edulis e P. alata) enxertados sobre Passiflora cincinnata

The present work aimed to evaluate the initial growth and leaf mineral levels in passion fruit trees (Passiflora edulis f. flavicarpa Deg., P. edulis f. edulis Sims. and P. alata Dryander) grafted onto Passiflora cincinnata. To obtain seedlings, seeds were sown in plastic bags (500 mL) and hypocotyl grafting was performed when seedlings reached the stage of two fully expanded leaves. Fifteen days after grafting, plants were transplanted to 10L pots filled with previously limed and fertilized soil. Each pot contained two plants and corresponded to one plot. For each commercial species studied as rootstock, experimental design was completely randomized, in 3x5 (plant type x time of harvest) factorial arrangement, with four replicates of two plants per plot and five destructive harvests. Plant types were ungrafted P. cincinnata, ungrafted commercial passion fruit tree and commercial passion fruit tree grafted onto P. cincinnata. The first harvest was performed at 15 days after transplanting and the remaining ones at 14-day intervals (60, 74, 88, 102 and 116 DAS). At each harvest, the number of leaves per plant was counted, and leaf area, stem length, and stem, root, leaf and total dry matter were estimated. At the last harvest, the mineral composition (macro and micronutrients) of plants was analyzed. In general, it was observed that grafting onto P. cincinnata did not interfere negatively with the initial development and mineral levels of commercial passion fruit trees, and this interference varied according to the used canopy.
