Ella alberga la mayor extensión de bosque pluvial tropical donde vive más de la mitad de las especies de animales, plantas e insectos de nuestro planeta. Este inmenso océano verde desempeña un rol vital en la regulación del clima de la Tierra, la purificación del agua y la absorción de carbono. El Perú es un país agraciado por la naturaleza. Su región más extensa y biodiversa es, precisamente, la Amazonía.
ArtículoCacao: The Treasure Of The Amazon(Universidad San Ignacio de Loyola, 2018-08) De la Fuente de Diez Canseco, Luciana ; Zavaleta Melgar, Juana ; Olivera Montenegro, Luis ; Gómez Mendoza, José ; Ramos Escudero, Fernando ; Cárdenas Jarama, Martín ; Valdizán Ayala, José ; Muñoz Jáuregui, Ana María ; Guzmán Vega, Carolina ; Matsuda Gushiken, Rosalba ; Rosales Buendia, Alexis ; Velázquez Menacho, Lorena ; Roncal Ballena, Jaqueline ; Olano Dávila, Paul ; Ponce Yalico, Frank ; Rojas Trigoso, Michael ; Hilasaca Mamani, César ; Parraguez Santisteban, JulioThe world would not be as it is today without the Amazonia. It is home to the largest area of tropical rainforest where more than half of our planet’s animal, plant and insect species live. This immense green ocean plays a vital role in the regulation of the Earth’s climate, the purification of water, and the absorption of carbon. Peru is a country blessed by nature. Its largest and most biodiverse region is the Amazonia. According to the National Ministry of the Environment, the Amazonia covers, in its entirety, the departments of Loreto, Ucayali, and Madre de Dios; almost entirely, the departments of San Martín and Amazonas; very partially, the departments of Pasco, Junín, Huánuco and Cusco; and, finally, certain protected areas of Cajamarca, Puno and Ayacucho.
ArtículoCharacterization of commercial Sacha inchi oil according to its composition: tocopherols, fatty acids, sterols, triterpene and aliphatic alcohols(Springer India, 2019) Ramos Escudero, Fernando ; Muñoz, Ana María ; Ramos Escudero, Mónica ; Viñas Ospino, Adriana ; Morales Millán, M. T. ; García Asuero, AgustínSacha inchi oil (SIO) is one of the largest vegetable oil exports in Peru, used for consumption, in the food industry, cosmetics, and pharmaceuticals; it represents a significant economic income for producers. This study addresses the characterization and quantification of fatty acids, tocopherols, sterols, and alcohols of commercial Sacha inchi oils from Peru. Some of the SIO samples received had a high substance consistency, while others differed in the compounds studied. The results showed that some of the commercialized oils present high levels of γ-tocopherol and δ-tocopherol, while other samples had variable fatty acid compositions; especially in α-linolenic, linoleic, oleic and palmitic acids. Fourteen sterols and eleven alcohols were identified (β-sitosterol, stigmasterol, campesterol, Δ5-avenasterol, triterpene alcohol, lanosterol isomer 1 and cycloartenol) being the major components. Some SIO samples presented the following ratios: The δ-tocopherol/γ-tocopherol ratio was 0.33–0.81, ω-6/ω-3 ratio was 0.77 and a stigmasterol/campesterol ratio of 3.13. The presence of brassicasterol in some commercial oils indicates the addition of rapeseed or canola oil. Tocopherols, fatty acids, sterols and alcohol data provided a classification of SIO samples, by an efficient k-means clustering algorithm analysis. The ANOVA found significant differences between clusters for palmitic acid, oleic acid, γ-tocopherol, δ-tocopherol, campesterol and stigmasterol; these compounds could be used as markers of authenticity in commercial Sacha inchi oils.
ArtículoOrganically vs conventionally-grown dark and white chia seeds (Salvia hispanica L.): fatty acid composition, antioxidant activity and techno-functional properties(Instituto de la Grasa CSIC, 2019-02-11) Alvites Misajel, Kiara Carolina ; Garcia Gutierrez, Mirina ; Miranda Rodríguez, Camila Lucía ; Ramos Escudero, FernandoThe effects of organic and conventional crop systems on chemical composition, antioxidant activity and functional properties were evaluated in white and dark chia (Salvia hispanica L.) seeds. The organic system reduced the total protein content, and increased the total carbohydrates but did not change polyunsaturated fatty acids, total phenolic or flavonoids. Organic white chia seeds showed the best techno-functional properties. The antioxidant capacity of chia extracts varied in relation to the chemical complexity and differential rate kinetics of different assays. Extractable total phenolic acids and antioxidant capacity were better in organic white chia seeds. In this first approach, we have demonstrated that the organic white chia seed has a better total antioxidant capacity measured by direct quencher approaches than its conventionally-grown counterpart. To summarize, we conclude that the organic white chia seed could be a dietary source of antioxidants with a potential to promote health benefits in systemic functions and/or microbiota and the use of its techno-functional properties for the food industry.
