“…From this tree, it is possible to use its almond inside the seeds and its resin that, when distilled, provides several products with many industrial applications (Quinteiro et al, 2019); among these products derived from Araucaria, stands out its seeds with its common name—pinhão (Cordenunsi et al, 2004), whose harvest has been an important source of income in several regions in the southern part of Brazil (Tagliari & Peroni, 2018).…”

The seeds from Araucaria angustifolia—commonly named as pinhão—are important culturally, and viable regional food from Brazil. Although now considered an endangered species, methods to increase the awareness of this tree have been called upon attention. In light upon increasing such awareness, we utilized the seed coats of pinhão, which is considered a residue and discarded, in the development of cereal bars. Although the raw seed coats have a very high astringent flavor and impair the sensory taste; if considered as a nanoformulation, this strong astringent flavor is masked. Therefore, studies were also carried out with an experimental design to understand the effect of nanosuspension as a binding agent. In addition to physicochemical and nutritional characteristics performed, the results propose that nanosuspension of pinhão seed coats can be a potential ingredient for functional cereal bars due to high fiber content, proteins, and phenolic compounds. Practical applications Nanosuspension of pinhão seed coats masks the astringent flavor of the raw seed coat, while also able to present high fiber content and is very resistant as cereal bar due to nanocellulose. Cereal bars also present good acceptability index and high values of proteins, with presence of phenolics compounds extracted from the seed coat.

“…The very few regulations about pinhão harvesting are limited to the beginning of the season extraction (usually from 1 st April in Paraná and Santa Catarina states; or 15 th April in Rio Grande do Sul; we found no information for São Paulo and Minas Gerais states). However, the majority of extractors usually gather and trade pinhão for nancial subsistence and food security, and not to guarantee the species conservation, ecosystem maintenance, or sustainable harvesting (Adan et al 2016;Tagliari and Peroni 2018;Quinteiro et al 2019;Tagliari et al 2021a). The lack of environmental incentives, especially via Payment for Ecosystem Services (Tagliari et al 2019), promote, especially for landowners, antagonistic conservation practices, such as the araucaria seedling suppression (Tagliari and Peroni 2018;Schneider et al 2018;Quinteiro et al 2019).…”

“…The nutritious pinhão structures the associate vertebrate consumers spatiotemporally (Oliveira-Filho et al 2015;Bogoni et al 2020a). Furthermore, the species is also valuable due to the ancient connection with Indigenous peoples and local communities (Reis et al, 2014;Robinson et al, 2018), who still use and manage pinhão (Adan et al 2016;Quinteiro et al 2019). Forest management strategies by human groups since the last 1400 years expanded the Araucaria Forest beyond its natural boundaries, with landscape modi cations visible in present days (Robinson et al 2018;Cruz et al 2020).…”

“…Forest management strategies by human groups since the last 1400 years expanded the Araucaria Forest beyond its natural boundaries, with landscape modi cations visible in present days (Robinson et al 2018;Cruz et al 2020). Currently, the traditional management systems by local smallholders: (i) maintain forest fragments productive (Mello and Peroni 2015); (ii) promote ecosystem services (Tagliari et al 2019) and temporal food security to local fauna and human groups (Adan et al 2016;Bogoni et al 2020a); (iii) preserve cultural, social, and economic dynamics in this SES (Zechini et al 2018;Tagliari et al 2021a); and (iv) maintain the functional diversity of araucaria, especially due to pinhões ethnovarieties identi cation thanks to TEK holders (Adan et al 2016;Tagliari and Peroni 2018;Quinteiro et al 2019). These traditional systems under TEK holders also boost positive feedbacks which might expand Araucaria Forest (Tagliari et al 2021a).…”

Socioecological systems (SES) hinge on human groups and ecosystems, promoting interdependence and resilience to environmental disturbances. Climate change effects propagate from organism to biomes, likely influencing SES. In southern Brazil, Araucaria Forest is a typical SES due to the historical interaction between humans and biodiversity. We thus aimed to evaluate empirically and theoretically how climate change could disrupt this system by interviewing 97 smallholders and assessing their Traditional Ecological Knowledge (TEK). We evaluated and measured: (i) socioeconomic impact of araucaria’s nut-like seed (pinhão) trade; (ii) ethnoecological knowledge about climate change; and (iii) generated an ecosystem services network. We projected these empiric data with a projected loss of 50-70% of the Araucaria Forest due to climate change to quantify the risks of the potential disruption of this socioecological system. We found evidence that to avoid the disruption of the Araucaria Forests is paramount to value TEK holders, safeguard the historical socioecological interaction, and promote non-mutually exclusive measures in an integrative response to maintain the Araucaria Forests resilient to future disturbances.

“…Its peel is red and has an edible pulp that is too hard to consume in natura. As a result, the seeds must be processed to soften their texture prior to consumption (Zortéa-Guidolin, Carvalho, Godoy, Demiate, & Scheer, 2017;Quinteiro, Alexandre, & Magalhães, 2019).…”

Microwave drying has shorter processing times compared with convection drying, which results in high-quality products and reduced energy consumption. The objective of this study is to evaluate the drying process of Araucaria angustifolia seeds using hot air at atmospheric pressure by applying microwaves (300 W and 500 W), and comparing them with the conventional drying process using hot air (80 °C). The drying time using hot air with microwaves at 500 W and 300 W was reduced by 83.33% and 73.89%, respectively, compared with conventional drying. The drying process occurred in the transient regime, with the predominance of a period of decreasing drying rate. The internal temperature of Araucaria seeds increased with the exposure time to the drying process, whereas the moisture content decreased. This tendency was greater for seeds subjected to electromagnetic fields, especially those exposed to higher power. The total phenolic compounds (TPCs) were lower by microwave drying when compared with conventional drying. The TPC loss was influenced by the internal temperature of the seed. Alternative methods to promote the increased retention of phenolic compounds during the drying process include decreasing the microwave power before the end of drying, combining traditional microwave-associated drying methods, and controlling the applied microwave power.
