“…These seeds, called pinhão, are collected by small producers as an alternative for sustainable income (Carvalho et al, 2020). They are rich in starch, proteins, and flavonoids, presenting high nutritional value (Brandão et al, 2019). The use of pinhão bio-waste as a sustainable alternative has been proposed by several research groups, which have evaluated different strategies, such as, for example, the use of sterile bracts as a natural absorbent to remove methylene blue from aqueous solutions (Matias et al, 2019) and pinhão seed coats as a source of antimicrobial extract (Trojaike et al, 2019), as well as to produce extracts with other bioactive properties (Branco et al, 2019;da Silva et al, 2014;Koehnlein et al, 2012;Peralta et al, 2016;Souza et al, 2014).…”

Pinhão residues have a wide range of bioactive compounds and encapsulation can be one of the alternatives to increase their bioavailability. Thus, this work aimed to apply pinhão extract, pure and encapsulated by solid dispersion, in the formulation of cookies as a bioactive ingredient. For that, pinhão extract was encapsulated in different biopolymers (sodium caseinate, gelatin, and gum arabic) and with different shear mechanisms (sonication, Ultra-Turrax, and magnetic stirring). The best encapsulation procedure has been defined by a chemometric analysis (hierarchical cluster analysis), considering thermal properties (DSC) of particles and ( +)-catechin encapsulation efficiency (HPLC). The optimized conditions were gelatin as encapsulation agent and Ultra-Turrax as shear mechanism (70.1 ± 2.8 °C maximum endothermic peak temperature and 96.0 ± 2.3% ( +)-catechin encapsulation efficiency). The phenolic profile of the encapsulated extract showed the presence of ( +)-catechin (0.31 ± 0.01 (mg/g particle ), protocatechuic acid (0.29 ± 0.00 mg/g particle ), and ( −)-epicatechin (0.11 ± 0.00 mg/ g particle ). Both the pure and encapsulated extracts were incorporated into the cookie formulation, which was characterized in terms of centesimal composition, color parameters, texture, and sensory aspects. It was found that cookies with the pure and the encapsulated extract showed significant differences concerning the centesimal composition, products added with pinhão extract and encapsulated extract presented higher values when compared to the control, probably influenced by the mineral content of the pinhão. In addition, higher hardness values were detected for cookies formulated with the encapsulated extract, which possibly negatively affected the consumer's sensory perception.

“…Oceania, an area of the South Pacific Ocean, is home to 17 species, 13 of which are indigenous to the small archipelago of New Caledonia. The last two species (A. araucana and A. angustifolia) are abundant in southern South America [15,16]. Their distinctive and recognizable crown silhouette effortlessly identifies the araucarias.…”

The members of the genus Araucaria (Araucariaceae) are evergreen coniferous trees, widely used for medicinal, ornamental, and timber purposes. This overview includes the phytochemical, medicinal properties, and biological activities of various species of Araucaria. In this study, the most recent scientific research has been compiled from various publications to focus on the untapped potential of Araucaria species. There are twenty species in the genus Araucaria. The species of Araucaria have been found to produce resins, a complex combination of terpenoids and phenolics, with terpenoid resins being the majority. Besides, the prevalence of diterpenoids in the species of Araucaria, bioflavonoids, isoflavones, sesquiterpenes, polysaccharides, phenylpropanoids, lignans, and other phenolics have also been isolated. Phyllocladene, hibaene, 16-kaurene, luxuriadiene, and sclarene were the most abundant diterpenoids, whereas βcaryophyllene, germacrene D, bicyclogermacrene, and spathulenol were the most widely distributed sesquiterpenoids. Monoterpenoids are often identified as α-pinene, sabinene, myrcene, limonene, and γ-terpinene. A thorough review of the literature revealed that different species of Araucaria possess a diverse range of biological activities, including antibacterial, cytotoxic, anti-inflammatory, gastro-protective, wound healing, antidiabetic, anti-rheumatoid, anticancer, antidepressant, and sedative properties. Studies showed a lot of potential in exploring the phytochemical and pharmacological properties of Araucaria species, specifically resins and essential oils.
