Abstract
ABSTRACT: Araucaria angustifolia characterizes mixed Ombrophilous Forests. This Paraná pine tree has been of great economic, cultural and social importance for southern Brazil. Its cutting is restricted, as it is threatened with extinction and the use of its seed has been encouraged. This study highlights scientific research on this conifer by bibliometric analysis and reviews trends in new research on its seed and some of its food applications. The Web of Science© database revealed 620 scientific articles and the bibliometric analysis through VOSviewer showed the worldwide interest in growing. The increase in research in the areas of silviculture, phytoscience and ecology reflects the concern with the preservation of “Matas das Araucárias”. Concurrently, research in food science and technology has increased, as pine nut seed can produce starch-rich food flour with low glycemic response and source of dietary fiber and some minerals. Also, along with its husk, provide bioactive compounds with potential application in the special food, active/smart and reinforced packaging and even pharmacological industries.
