Kipu 4. El mundo indígena en la prensa ecuatoriana Enero – Junio 1985

Una de las prioridades del Centro Abya-Yala ha sido, desde sus orígenes, los pueblos indígenas. Sistemáticamente, Abya-Yala revisa la prensa ecuatoriana y recoge todo aquello que ha aparecido y lo publica en su Kipu cada seis meses. ¿Para qué? Es una manera de sistematizar la mirada de la sociedad mestiza sobre las particularidades indígenas; un termómetro de la realidad que vuelve la mirada sobre los indígenas como protagonistas de la historia; una urgencia. Kipu está al alcance de investigadores, académicos, líderes indígenas, estudiantes, lectores curiosos. Un trabajo minucioso y sistemático que recoge los facsímiles de los periódicos del Ecuador

Evaluación de las propiedades fisicoquímicas y funcionales del polen apícola colombiano

Objective. To establish current knowledge about Colombian bee-pollen from a point of view nutritional and functional, contributing towards creating national technical standards and the identification of chemical differentiation factors for further researches. Material and methods. One hundred ninety-six samples of dried bee pollen were collected in the center region of Colombia known as Cundi-boyacense high plateau, where nearly 90% of total bee pollen production is concentrated in this country. Performed physicochemical analyses in this study were: moisture, pH, acidity, ash, carbohydrates, lipids, proteins, dietary fiber, fatty acid profile and mineral elements. Results. Bee pollen from this region had 7.7\ub15.2 g/100 g moisture content, and a following centesimal composition based on dry matter: ashes 2.5\ub10.4 g; lipids 6.90\ub13.5 g; proteins 23.8\ub13.2 g and total dietary fiber 14.5\ub13.5 g. The most abundant fatty acids were a-linolenic, palmitic and linoleic. Carbohydrates were the main components and fructose and glucose the most concentrated sugars. The predominant minerals assessed here were potassium, calcium and magnesium. The results were also discussed in terms of the characteristics found in Colombian bee-pollen in comparison to international regulations and findings for other varieties of commercial bee-pollen from eight different countries. Conclusions. The results found in this study suggest that bee-pollen may be used as a dietary supplement and agree with bibliographical reports and international regulations. Such characterization will enable to be proposed technical standards in line with Colombian bee-pollen properties and it is expected to improve marketing and production chain conditions
