Pasteurização do leite-do-amapá in natura para controle do escurecimento enzimático

Background: Information on the knowledge, management and ways of using food and medicinal plants by traditional populations, family farmers and Brazilian native population in the Amazon is essential to guarantee the sovereignty of these groups. The objective of this study was to evaluate the diversity, knowledge and ways of using non-conventional food and medicinal plants in traditional communities in a conservation unit in the Brazilian Amazon.Methods: This study was conducted using semi-structured interviews applied to local respondents. Fifty-six residents were interviewed in 26 communities. The Indices of Use Value (UVI) and relative frequency of species citation (Fr) were evaluated; also, their diversity and equitability using the Shannon- Wiener (H’) Pielou (J’) indices, respectively. The species were listed according to their family, scientific name, popular names, categories of use, propagation environment, growth habit, medicinal indications, domestication status, production cycle and herbarium registration.Results: A total of 269 species of both non-conventional food and medicinal plants were identified, distributed in 83 botanical families, 198 genera, in addition to 13 unidentified species. The Arecaceae and Lamiaceae families had the highest species richness (11 and 7, respectively). Eryngium foetidum L. (Apiaceae) and Ipomoea potatoes L. (Convolvulaceae) presented the highest relative citation frequencies (19.7 and 19.3, respectively) and the highest index of use value of the species (0.94 and 0.92, respectively). The Shannon-Wiener (H’) and Pielou (J’) diversity indices were considered high (5.02 and 0.9, respectively) when compared to other ethnobotanical works carried out in Brazil and in the Amazon.Conclusions: A wide relationship of use was observed between the species under study and the population of this conservation area. In the environment in which these families are found, of geographical isolation and distance from urban centers, these species become, in many circumstances, the only food and medicinal resources, therefore, being fundamental to the sovereignty of these families.

“…The amapá latex is a natural plant polymer containing a complex mixture of secondary metabolites, including phenolic compounds, secreted by laticiferous cells and exudated by various parts of the plant after suffering a minor tissue injury [28]. The total phenolic content of amapá latex from Belém, Marajó, Cametá and Mocajuba was 127.92 ± 4.89; 127.92 ± 10.74; 192.01 ± 13.43 and 121.04 ± 9.51 µg GAE.mL -1 latex, respectively.…”

Parahancornia amapa is an Amazonian tree that produces an edible white exudate widely used in folk medicine and food. Studies have found the presence of carbohydrates and bioactive compounds in its composition. The riverside population of the Amazon reports the use of this exudate against respiratory diseases and inflammation. This brief communication aimed to show the bioactive potential of the amapá bitter latex. Samples obtained from four different cities were studied and microbiological, physicochemical, mineral, and bioactive compounds were analyzed (Total Phenolic and antioxidant activity by ORAC and FRAP methods). The results showed relevant physicochemical and mineral composition (Ca, Mg and Zn values suggested by the RDA). Furthermore, we found good antioxidant activity throughout latex. The sample from the city of Cametá-PA showed higher values for Total phenolics, and antioxidant activity ORAC and FRAP, respectively. This study is important due to the interesting composition of Parahancornia amapa, which has the potential to be applied in technological routes in the food area.
