Plantas alimentícias não convencionais uma revisão sistemática dos artigos indexados a partir de estudos realizados no Brasil

Abstract

It is estimated that in Brazil there are about 3 thousand species of edible plants, with almost 10% of the native flora characterized as a food species, many still unknown or even despised by a large part of society, resulting mainly from the lack of knowledge of what can be use as food. In this context, there are the unconventional Arboreal Food Plants, which have little research and a lack of basic information about their resources. Therefore, the general objective of this study was to carry out a survey of the Brazilian scientific production and its main findings about unconventional food plants, with an emphasis on tree species. To this end, a systematic review was carried out on research involving unconventional food plants in Brazil. To select the reviewed papers, searches were carried out in the Scielo, Scopus, Science Direct and Web of Science databases, using keywords in Portuguese and English, they are: unconventional food plants, wild edible plants, wild food plants, emergency edible plants, emergency food plants (native fruits, native food plants). The following criteria were adopted to select the reviewed articles: 1) Be an article with a national study area; 2) Address the knowledge and / or use of PANC, which may include other categories; 3) Have scientific identification of plants; and 4) Be published from December 2000. Thus, 22 articles were selected for review, in which different terminologies are adopted to fit the PANC. Most of these works come from public institutions, with a greater number of studies in the Caatinga and Cerrado biomes, followed by Mata Atlântica and Pampa. A total of 264 species were registered, distributed in 133 genera and 49 botanical families, where Cerrado and Caatinga concentrate the largest amount of records. Thus, it was concluded that despite the small number of studies on PANC in Brazil, the number of institutions that address this theme grows, in which different terminologies are used to refer to this group of plants, with studies focused on northest region of the country, and with species that point to the potential of the great plant diversity existing in our flora.
