Methods of seed germination and suitable substrates for seedling growth of gurguéia nut (Dipteryx lacunifera) were studied in the present work. The following methods of seed germination i.e. I and II) Room temperature water soak for 24 and 48 hours; III, IV, V and VI) hot water soak, for 5, 10, 15 and 20 minutes, respectively; and VII) mechanical scarification, were studied. The studied substra...

The objective was to determine the nutritional and functional characteristics of cookies with addition Gurguéia nut soursop residue. Three whole-grain cookie formulations were developed from a standard (SC). Whole-grain 2 (WC2) had greater acceptance preference. Proximate composition, microbiological, bioactive compound analyses performed for WC2 SC. exhibited higher levels proteins, lipids, as...

In this work Eucalyptus grandis and Dipteryx odorata were submitted to photodegradation by ultraviolet radiation. The effect of ultraviolet radiation irradiation on the color change and chemical composition of each wood flour were evaluated. The samples were submitted to a total of 500h of artificial weathering using condensation stages and ultraviolet radiation B irradiation cycles. The change...

The influence of wood components and cellulose crystallinity on the thermal degradation behavior of different wood species has been investigated using thermogravimetry, chemical analysis and X-ray diffraction. Four wood samples, Pinus elliottii (PIE), Eucalyptus grandis (EUG), Mezilaurus itauba (ITA) and Dipteryx odorata (DIP) were used in this study. The results showed that higher extractives ...
