We present the chemical composition, quality parameters and antioxidant capacity of pumpkin seed oils (PSO) from Cucurbita pepo, Cucurbita maxima, and Cucurbita moschata cultivated in Brazil. In addition, PSO nanoemulsions (nanopepo, nanomax and nanomosc) were developed and their physical stabilities were assessed under long-term storage at two temperatures. Among the PSO, C. pepo presented the highest contents of polyunsaturated fatty acids, total carotenoids, and chlorophylls, but the lowest oxidative stability. Conversely, C. maxima PSO showed highest oxidative stability and total tocopherol content but the lowest chlorophyll content. Nanomax and nanopepo were more stable to droplet growth at 4 ◦C, while nanomosc was more stable at 25 ◦C. Nanopepo was the most stable formulation after the heating?cooling cycles, whereas nanomax was the most stable under centrifugation regardless the temperature. Overall, all nanoemulsions presented droplet diameter lower than 200 nm and ζ-potential approaching -30 mV until the end of storage. |

The social entrepreneurship has evolved into a complex framework of political, economic and social changes which occurs globally and locally. This study aimed to demonstrate how the social entrepreneurship can contribute on the development of local communities using an applied practical experience in the insular region of Belém. The generation of income from agricultural production, both for subsistence consumption and to marketing has been used as a tool for social promotion by the community in partnership with Embrapa Amazonia Oriental. The research methodology involved bibliographical research and field, using interviews and testimonials provided by community residents. The research showed that the formation of social entrepreneurs is possible through the creation of associative networks of local sustainable and integrated development as a promising alternative to the generation of employment and income for socially excluded families with a help from big companies. |
