Azeites com denominação de origem protegida (DOP): estudo comparativo das DOPs portuguesas azeite de Trás-os-Montes, azeite da Beira Interior e azeite do Alentejo Interior

xiii Resumo Os países da União Europeia (UE) caracterizam-se por possuir uma grande diversidade de alimentos tradicionais com caraterísticas diferenciadoras. No sentido da sua proteção, foi criado o Regulamento (UE) n.º 1151/2012 que estabelece três regimes de qualidade a Denominação de Origem Protegida (DOP), a Indicação Geográfica Protegida (IGP) e a Especialidade Tradicional Garantida (ETG). Atualmente Portugal possui seis DOPs de azeite a maioria criadas em 1996. No entanto, existe pouca informação acerca da composição química, dos parâmetros de qualidade e dos atributos sensoriais dos azeites classificados com DOP. Para além do mais, a informação contida nos cadernos de especificações da maioria das DOPs não foi atualizada nem revista após a sua publicação. Assim, o presente trabalho tem como objetivos proceder ao levantamento das regiões pertencentes à UE com regime de qualidade DOP e IGP para azeites e realizar um estudo comparativo dos parâmetros de qualidade, do perfil sensorial e volátil, da atividade antioxidante e da estabilidade oxidativa de azeites de três DOPs portuguesas, nomeadamente, “Azeite de Trás-os-Montes”, “Azeite da Beira Interior” e “Azeite do Alentejo Interior”. Para dar resposta ao primeiro objetivo foi realizada uma pesquisa orientada por vários parâmetros facultados pelas bases de dados eAmbrosia e GIview. De forma a concretizar o segundo objetivo foram recolhidos 10 lotes diferentes de azeite virgem extra de produtores das três regiões selecionadas os quais foram, posteriormente, analisados. O levantamento efetuado revelou que, em 2022, se encontravam estabelecidas 112 DOPs e 21 IGPs. Os países Itália, Espanha e Grécia são os que possuem um maior número de DOPs de azeite, e são os únicos que possuem IGPs para este produto. Em relação ao estudo comparativo constatou-se que os azeites das três DOPs respeitavam os limites legais para a categoria, assim como, os indicados nos seus cadernos de especificações. No perfil sensorial foram identificadas sensações de frutos e herbáceas não mencionadas nos cadernos de especificações. Além disso, ocorreram diferenças estatisticamente significativas entre regiões ao nível de todas as análises efetuadas permitindo o agrupamento dos azeites conforme a sua origem geográfica. Futuramente, seria importante que as entidades competentes revessem os cadernos de especificações das DOPs. Para além disso, seria relevante realizar outras análises como a determinação do perfil fenólico de forma a contribuir para uma melhor diferenciação das DOPs.The countries of the European Union (EU) are characterized by having a great diversity of traditional foods with differentiating characteristics. To protect them, Regulation (EU) No 1151/2012 was created, which establishes three quality schemes, the Protected Designation of Origin (PDO), the Protected Geographical Indication (PGI) and the Traditional Speciality Guaranteed (TSG). At the moment, Portugal has six olive oil PDOs, most of them created in 1996. However, there is little information about the chemical composition, quality parameters and sensory attributes of oils classified with PDO. Furthermore, the information contained in the specifications of most PDOs has not been updated or revised after publication. Thus, the present work aims to survey the regions belonging to the EU with a PDO and PGI quality schemes for olive oils and carry out a comparative study of the quality parameters, the sensory and volatile profile, the antioxidant activity, and the oxidative stability of olive oils from three Portuguese PDOs, namely “Azeite de Trás-os-Montes”, “Azeite da Beira Interior” e “Azeite do Alentejo Interior”. To achieve the first objective, a search was carried out guided by several parameters provided by the eAmbrosia and GIview databases. To achieve the second objective, 10 different batches of extra virgin olive oil were collected from producers in the three selected regions, which were subsequently analyzed. The survey carried out revealed that, in 2022, 112 PDOs and 21 PGIs were established. Italy, Spain and Greece are the countries with the highest number of PDOs for olive oil and are the only ones that have PGIs for this product. Regarding the comparative study, it was found that the oils from the three PDOs respected the legal limits for the category, as well as those indicated in their specifications. In the sensory profile, fruits and herbaceous sensations not mentioned in the specifications were identified. In addition, there were statistically significant differences between regions in terms of all the analyzes carried out, allowing the grouping of olive oils according to their geographical origin. In the future, it would be important for the competent authorities to review the PDO specifications. In addition, it would be relevant to carry out other analyzes such as the determination of the phenolic profile to contribute to a better differentiation of PDOsProjeto: “OLIVE4ALL - Património Olivícola para o Desenvolvimento Sustentável: Sensibilização da Comunidade para o Património Vivo (JPICH/0001/2020)”, financiado pela Fundação para a Ciência e Tecnologi

Finding positive health in “fortalezas” and “comunidad”: A case study of Latinos/X in Sonoma Valley

Background: Psychological literature and needs-assessment reports emphasize that Latinos/X in Sonoma Valley continue to be impacted by the detrimental effects of the 2017 Northern California wildfires (Domínguez & Yeh, 2018), current immigration enforcement practices, higher rates of poverty, lower educational attainment, persistent barriers to health care access, and obstacles to proportionate leadership representation compared to White American families. To cope with these disparities and navigate life adversities, Sonoma Valley Latinos/X often rely on “fortalezas” [strengths] and community, political, spiritual, cultural, and physical assets. These assets, which often include meaningful interactions with family, friends, neighbors, folk healers, faith-based organizations, and community members, must be incorporated when health care, community, and social service initiatives are designed and implemented. Method: Our community-engaged research team (CERT) used asset-based community development (ABCD) as a conceptual framework (Kretzmann & McKnight, 1993) and community-based participatory research (CBPR) (Wallerstein & Duran, 2003) as a methodological approach to explore the assets and “fortalezas” [strengths] that have enabled Latinos/X to overcome adverse experiences i n Sonoma Valley. Five focus groups and 29 in-depth interviews were conducted because these methods are well-suited for Latino/X relational styles of “platicando” [small talk] (Delgado-Romero, Singh, & De Los Santos, 2018) . Participants were 18 years or older, lived or worked i n Sonoma Valley, and self-identified as Latino/X. Our sample included Latino/X parents, grandparents, artists, folk healers, health and social service providers, community leaders, students, and school personnel. Specific locations where interviews took place include the Hanna Institute, Nuestra Voz, La Luz Center, Center for Well-Being, Boys and Girls Clubs of Sonoma Valley, the Family Resource Center in El Verano, the Sonoma Valley Community Health Center, participants’ houses, and the broader Sonoma Valley community. Our research prioritized depth of relational engagement rather than sample size (Bowden, Caine, Yohani, 2017). We discontinued data collection once our research objectives were achieved and data saturation was accomplished. For data analysis, we used quasi-statistics to quantify the frequency of asset endorsement; open, axial, and selective coding to identify and categorize the assets; and GIS software for the creation of our two asset maps. Findings: Findings indicate that Latinos/X are marginally positioned within Sonoma Valley society. Latinos/X have coped with and adapted to adverse conditions and disparities using and relying on a variety of informal networks and formal sources of support. Their decision to rely on one source of support over another is often based on (a) the extent to which they can afford the services or support required; (b) their particular needs, goals, or objectives at the time the help i s needed; (c) their preference for support resources that honor “respeto” [respect], “personalismo” [a preference for close personal attention i n relationships], and stable and welcoming intimate relationships with others; (d) the accessibility associated with pursuing these support services (e.g., geographic and transportation limitations); and (e) the extent to which culturally relevant and Spanish-speaking support can be found. Dissemination: All data i n this study i s co-owned with the Sonoma Valley community. With the help of our community partners, this report was disseminated in Sonoma Valley during community meetings and forums, offering residents the opportunity to provide feedback, debate preliminary results, and assess whether their voices were captured accurately. Once the community expressed that the findings were representative of the Latino/X experience in Sonoma Valley, we finalized recommendations to assist community members, government officials, and health care and social service providers in designing culturally informed social, health, and/or community programs

Electronic nose: a tool to verify the PDO declaration of Portuguese olive oils

The volatile and olfactory profiles of three Portuguese olive oils with protected designations of origin (PDO) were studied: "Azeite do Alentejo Interior", "Azeites da Beira Interior", and "Azeite de Tras-os-Montes". Seven classes of volatiles were identified, with aldehydes, followed by hydrocarbons and alcohols, the most prevalent (5.63, 2.92, and 2.79 mg/kg olive oil, respectively). The "Azeites da Beira Interior" oils exhibited the highest amount of volatiles (18.2 +/- 4.6 mg/kg olive oil) compared to the oils from the other two PDOs. Ten positive olfactory sensations were detected, and a significant effect of the PDO on the intensities of fruity, apple, cabbage, tomato, dry and fresh herbs was observed. Specifically, "Azeite do Alentejo Interior" PDO oils were characterized as fruity-ripe, while "Azeite de Tras-os-Montes" PDO oils were labelled as fruity-green. Conversely, "Azeites da Beira Interior" PDO oils encompassed both fruity-ripe and fruity-green oils. Unique volatile and olfactory fingerprints were established for each PDO, allowing the linear discrimination of the oils according to the PDO, with a predictive sensitivity of 98.0 +/- 4.2% (repeated K-fold-CV). Furthermore, a lab-made electronic nose successfully discriminated the studied oils based on the PDO, with a predictive accuracy of 99.7 +/- 2.0% (repeated K-fold-CV). This device also allowed predicting the concentrations of the three main volatile classes found in the oils through multiple linear regression models (R2 >= 0.923 +/- 0.101 and RMSE <= 1.32 +/- 0.72 mg/kg oil; repeated K-fold-CV). These findings underscore the potential of the electronic nose as a reliable traceability tool to authenticate the PDO declaration of Portuguese olive oils, and broaden its use beyond non-PDO oils from a specific geographical area to encompass a national scale.The authors are grateful to the Foundation for Science and Technology (FCT, Portugal) for financial support by national funds FCT/MCTES (PIDDAC) to CIMO (UIDB/00690/2020, https://doi.org/10.54499/UIDB/00690/2020; and UIDP/00690/2020, https://doi.org/10.54499/UIDP/00690/2020) and CEB (UIDB/04469/2020) units as well as to the Associate Laboratory SusTEC (LA/P/0007/2020, https://doi.org/10.54499/LA/P/0007/2020).

Application of the FTIR technique as a non‐invasive tool to discriminate Portuguese olive oils with protected designation of origin

Three Portuguese olive oils with PDO (‘Azeite do Alentejo Interior’, ‘Azeites da Beira Interior’ and ‘Azeite de Trás-os-Montes’) were studied considering their physicochemical quality, antioxidant capacity, oxidative stability, total phenols content, gustatory sensory sensations and Fourier transform infrared (FTIR) spectra. All oils fulfilled the legal thresholds of EVOOs and the PDO's specifications. Olive oils from ‘Azeite da Beira Interior’ and ‘Azeite de Trás-os-Montes’ showed greater total phenols contents and antioxidant capacities, while ‘Azeites da Beira Interior′ presented higher oxidative stabilities. Linear discriminant models were developed using FTIR spectra (transmittance and the 1st and 2nd derivatives), allowing the correct identification of the oils’ PDO (100 % sensitivity and specificity, repeated K-fold-CV). This study also revealed that multiple linear regression models, based on FTIR transmittance data, could predict the sweet, bitter, and pungent intensities of the PDO oils (R2≥0.979±0.016; RMSE≤0.26±0.05, repeated K-fold-CV). This demonstrates the potential of using FTIR as a non-destructive technique for authenticating oils with PDO.The authors are grateful to the Foundation for Science and Technology (FCT, Portugal) for financial support by national funds FCT/MCTES (PIDDAC) to CIMO (UIDB/00690/2020 and UIDP/00690/2020) and to the Associate Laboratory SusTEC (LA/ P/0007/2020).

Frequência e variabilidade da morfologia dentária de oito grupos étnicos do sudoeste da Colômbia

Aim: To characterize the frequency and variability of the dental morphology of eight ethnic groups in southwestern Colombia. Method: Cross-sectional descriptive observational study that characterized the frequency and variability of dental morphology in eight ethnic groups in southwestern Colombia, through the prevalence, sexual dysmorphism, bilateral symmetry and biological distance of eight non-metric dental traits (shovelling, Carabelli trait, hypocone reduction, protostylid, deflecting wrinkle, cusp pattern, cusp 6 and cusp 7). Results: High shovelling frequencies were observed in indigenous from Jambaló, Morales and Silvia and in afro-descendants from Cali; of the deflecting wrinkle in indigenous from Jambaló and afro-descendants from Villarica; of the cusp pattern in indigenous from Jambaló and Silvia and afro-descendants from Cali; and of cusp 7 in indigenous of Jambaló. The Carabelli trait and the cusp 6 presented medium and low frequencies in the eight ethnic groups. The observed sample did not present sexual dimorphism in any of the morphological features and there was bilateral symmetry in their expression. Significant differences were found in the expression of morphological traits except in the protostylid. Conclusions: The dichotomous expression presence/absence of the eight non-metric dental traits studied shows that the eight ethnic groups of southwestern Colombia conglomerate with respect to their biological affinity with populations with whom they share the influence of the mongoloid, caucasoid and negroid population dental complexes.Objetivo: Caracterizar la frecuencia y variabilidad de la morfología dental de ocho grupos étnicos del suroccidente colombiano. Método: Estudio observacional descriptivo de corte transversal que caracterizó la frecuencia y variabilidad de morfología dental en ocho grupos étnicos del suroccidente colombiano, a través de la prevalencia, dismorfismo sexual, simetría bilateral y distancia biológica de ocho rasgos morfológicos dentales coronales (forma de pala de los incisivos, cúspide de Carabelli, reducción del hipocono, protostílido, pliegue acodado, patrón cuspídeo, cúspide 6 y cúspide 7). Resultados: Se observaron altas frecuencias de forma de pala de los incisivos en indígenas de Jambaló, de Morales y de Silvia y en afrodescendientes de Cali; del pliegue acodado en indígenas de Jambaló y afrodescendientes de Villarica; del patrón cuspídeo en indígenas de Jambaló y de Silvia y afrodescendientes de Cali; y de cúspide 7 en indígenas de Jambaló. La cúspide de Carabelli y la cúspide 6 presentaron frecuencias medias y bajas en los ochos grupos étnicos. La muestra observada no presentó dimorfismo sexual en ninguno de los rasgos morfológicos y hubo simetría bilateral en la expresión de los mismos. Se encontraron diferencias significativas en la expresión de los rasgos morfológicos excepto en el protostílido. Conclusión: La expresión dicotómica presencia/ausencia de los ochos rasgos morfológicos dentales coronales estudiados evidencian que los ocho grupos étnicos del suroccidente colombiano se conglomeran respecto a su afinidad biológica con poblaciones con los que comparten la influencia de los complejos dentales poblacionales mongoloide, caucasoides y negroide.Objetivo: caracterizar a frequência e variabilidade da morfologia dentária de oito grupos étnicos do sudoeste da Colômbia.

A amostra observada não apresentou dimorfismo sexual em nenhum dos traços morfológicos e houve simetria bilateral em sua expressão. Diferenças significativas foram encontradas na expressão de características morfológicas, exceto no protostilídeo. Conclusão: a expressão dicotômica presença/ausência dos oito traços morfológicos dentais coronais estudados mostra que os oito grupos étnicos do sudoeste da Colômbia estão conglomerados no que diz respeito à sua afinidade biológica com populações com as quais compartilham a influência da população dentária mongolóide, caucasóide e negróide. complexos.

Encontrando los beneficios de la comunidad y sus fortalezas a la salud positiva: Un estudio de caso con Latinos/X

Antecedentes: La literatura psicológica y los informes que evalúan las necesidades de la comunidad, enfatizan que los Latinos/X en el Valle de Sonoma continúan siendo afectados por los efectos perjudiciales de los incendios forestales del norte de California de 2017 (Domínguez y Yeh, 2018), las prácticas actuales de aplicación de la ley de inmigración, tasas más altas de pobreza, menor nivel educativo, barreras persistentes para el acceso a la atención médica y obstáculos para una representación de liderazgo proporcional en comparación con las familias Blancas Americanas. Para hacer frente a estas disparidades y navegar por las adversidades de la vida, los Latinos/X del Valle de Sonoma a menudo confían en las fortalezas y en los activos comunitarios, políticos, espirituales, culturales y físicos. Estos activos, que a menudo incluyen interacciones significativas con familiares, amigos, vecinos, curanderos, organizaciones religiosas y miembros de la comunidad, deben incorporarse cuando se diseñan e implementan iniciativas de servicios sociales, comunitarios y de atención médica. Método: Nuestro equipo de investigación comprometido con la comunidad (CERT) utilizó el desarrollo comunitario basado en activos (ABCD) como marco conceptual (Kretzmann & McKnight, 1993) y la investigación participativa basada en la comunidad (CBPR) (Wallerstein & Duran, 2003) como un enfoque metodológico para explorar los activos y las fortalezas que han permitido a los Latinos/X superar las experiencias adversas en el Valle de Sonoma. Se llevaron a cabo cinco grupos de enfoque y 29 entrevistas individuales porque estos métodos son muy adecuados para los estilos relacionales de platica (pequeña charla) entre los Latinos/X (Delgado-Romero, Singh y De Los Santos, 2018). Los participantes tenían 18 años o más, vivían o trabajaban en el Valle de Sonoma y se autoidentifican como Latinos/X. Nuestra muestra incluyó padres Latinos/X, abuelos, artistas, curanderos, proveedores de servicios sociales y de salud, líderes comunitarios, estudiantes y personal escolar. Los lugares específicos donde se realizaron las entrevistas incluyen el Instituto Hanna, Nuestra Voz, el Centro La Luz, el Centro para el Bienestar, Boys and Girls Clubs del Valle de Sonoma, el Centro de Recursos Familiares en El Verano, el Centro de Salud Comunitario del Valle de Sonoma, las casas de los participantes y otros espacios en la comunidad. Nuestra investigación priorizó la profundidad del compromiso relacional en lugar del tamaño de la muestra (Bowden, Caine, Yohani, 2017). Suspendimos la recopilación de datos una vez que se lograron nuestros objetivos de investigación y se logró la saturación de datos. Para el análisis de datos, utilizamos cuasi-estadísticas para cuantificar la frecuencia de uso de los activos; codificación abierta, axial y selectiva; y software GIS para la creación de nuestros dos mapas de activos. Hallazgos: Los resultados indican que los Latinos/X están marginalmente posicionados dentro de la sociedad del Valle de Sonoma. Los Latinos/X se han enfrentado y se han adaptado a condiciones y disparidades adversas utilizando y confiando en una variedad de redes y fuentes de apoyo formales e informales. Su decisión de depender de una fuente de apoyo sobre otra a menudo se basa en: (a) la medida en que pueden pagar los servicios o el apoyo necesarios; (b) sus necesidades, metas u objetivos particulares en el momento en que se necesita la ayuda; (c) su preferencia por recursos de apoyo que honren el respeto, el personalismo [una preferencia por una atención personal cercana en las relaciones] y las relaciones cercanas estables y acogedoras con los demás; (d) la accesibilidad asociada con la búsqueda de estos servicios de soporte (por ejemplo, limitaciones geográficas y de transporte); y (e) la medida en que se puede encontrar apoyo culturalmente relevante y de habla hispana. Difusión: Todos los datos de este estudio son de propiedad conjunta con la comunidad del Valle de Sonoma. Con la ayuda de nuestros socios en la comunidad, este informe fue difundido en el Valle de Sonoma durante las reuniones y foros de la comunidad, ofreciendo a los residentes la oportunidad de proporcionar comentarios, debatir los resultados preliminares y evaluar si sus voces fueron capturadas con precisión. Una vez que la comunidad expresó que los hallazgos son representativos de la experiencia Latina/X en el Valle de Sonoma, establecimos las recomendaciones para ayudar a los miembros de la comunidad, los funcionarios del gobierno y los proveedores de servicios sociales y de salud a diseñar programas sociales, de salud, y/o comunitarios culturalmente informados

Percepción del comportamiento alimentario en los hogares de Cali para el primer trimestre de la cuarentena por COVID 19 en 2020

Introducción: en 2020, la Organización Mundial de la Salud (OMS) declaró la emergencia de salud pública por SARS-CoV-21; el 11 de marzo de 2020 se notificó la pandemia global por COVID-19 y el gobierno colombiano decretó para todas las ciudades el aislamiento preventivo obligatorio2. Para el mes de mayo, Cali reportó 1635 casos de COVID confirmados y 85 fallecidos por un virus con un 4,95% de letalidad3. Lo anterior influenció de forma importante las rutinas alimentarias de las familias durante el primer trimestre del periodo de confinamiento. Considerando que esta situación era atípica en el país, era necesario describir la percepción del comportamiento alimentario durante este primer trimestre de aislamiento preventivo obligatorio en la ciudad de Cali, considerandolas normas de bioseguridad establecidas para el periodo mencionado. Objetivo: describir el comportamiento alimentario de 1814 familias en Cali durante el primer trimestre de aislamiento preventivo obligatorio. Metodología: estudio cuantitativo, descriptivo transversal, con técnica de encuesta. Se aplicó un instrumento virtual compuesto por 28 ítems, que indagó el comportamiento alimentario de las familias. Discusión: se encontró que el 95,1% de los hogares percibió escasez y aumento de precios en alimentos que componen la canasta alimentaria familiar, y el 67,2% de las familias estuvieron preocupadas por la alimentación. Hubo un aumento en el consumo de alimentos y se modificó el número de tiempos de comida/día. Los hábitos alimentarios, ingesta de refrescos y consumo de alcohol también se modificaron durante confinamiento. Conclusiones: se puede afirmar que durante el primer trimestre de cuarentena por COVID-19 en Cali se modificó el comportamiento alimentario de las familias encuestadas, una de las razones estuvo relacionada con un cambio en los ingresos económicos, que afectó la cantidad de dinero disponible para alimentos. Durante este periodo se modificaron también los tiempos de comida y la variedad en la ingesta de alimentos. En general, se describieron aspectos que afectaron la seguridad alimentaria de las familias.Introducción: en 2020, la Organización Mundial de la Salud (OMS) declaró la emergencia de salud pública por SARS-CoV-21; el 11 de marzo de 2020 se notificó la pandemia global por COVID-19 y el gobierno colombiano decretó para todas las ciudades el aislamiento preventivo obligatorio2.

On March 11, 2020, the global pandemic due to COVID-19 was declared, with which the Colombiangovernment decreed mandatory preventive isolation in the country2. In May, Cali reported 1,635 confirmed COVIDcases and 85 deaths from a virus with a 4.95 % case fatality rate3. This situation affected families eating routines during this period. Considering that this situation was atypical in the country, it was necessary to describe the perception of feeding behavior during this first trimester of mandatory preventive isolation in the city of Cali, considering the biosafety standards established by the national government. Objetive: To describe the feeding behavior of 1,814 families in Cali during the first trimester of mandatory preventive isolation. Methodology: Cross-sectional, descriptive and quantitative study. A virtual instrument composed of 28 items was applied, which investigated the feeding behavior of the families. Convenience sampling. Results: The results show that the economic income of families, as well as the distribution of expenses within the home, were affected in the evaluated period. In addition, it was found that 95.1 % of households perceived shortages and price increases in foods that make up the family food basket; 67.2% of families were concerned about food. There was an increase in food consumption and the number of perhaps consider, meals per day was modified. Eating habits, soft drink intake and alcohol consumption also changed during confinement in the evaluated time. Conclusions: It can be affirmed families modified their feeding behaviors during the first quarter of quarantine due to COVID-19. Because the economic income of families was affected, the money available for food purchases was affected as well. During this time, perhaps consider: meal frequencies and, in general, the variety in food intake was also modified. Finally, the results suggest perhaps consider: a negative effect in the food security of families
