Morphological and thermal characterization of native starches from Andean crops

et al. 2011

We have characterized and compared the morphological and thermal properties exhibited by starches from different Andean crops. Starches were extracted from tubers, root, fruits, and other starch containing parts of different plants. Morphological characterization was carried out by means of light optical microscopy. Thermal analysis was performed by DSC. The morphological properties of starch granules as well as the gelatinization parameters vary considerably among plants sources. Feret's diameter of granule starches is related to the part of the plant from which starch is obtained corresponding the largest starch granules (≈42.5 µm) to tuber sources, whereas, smallest granules to root sources (≈8.9 µm). The specific enthalpies of gelatinization were in the range 9–18.7 J/g. An inverse correlation between specific enthalpies and specific surface area (SSA) for starch with water content of 75% indicates that starches with higher SSAs need less energy to complete the gelatinization process than those with lower SSAs. The results show that starches from Andean crops could be used as raw material for the production of new starch‐based thermoplastics.

“…Though few of the internet-posted documents concerning M. expansa obtained by us from 2012 on, were published in peer reviewed academic journals, they include bibliographies which led us to other documents (Rea and León, 1965;Rea, 1982;Izquierdo and Roca, 1998;Tapia, 1990Tapia, , 2007 on M. expansa.…”

Several documents concerning the history and growth of Mirabilis expansa (Ruiz and Pav.) Standl. (Nyctaginaceae), were found to be available by 2012 on international library and agency websites from South America. These documents, written in Spanish, had previously been difficult for this author to find in North America. Information in these documents and from additional papers and reports referenced in them, made it possible to summarize here what had been known historically about M. expansa. Modern research in Andean universities and agencies, completed but not seen by us prior to doing our research on M. expansa in southern Illinois, is included in the summary. Several points are covered in this material, including ideas on the origin of the crop, a list of indigenous names for the crop, and general descriptions of the appearance of several unnamed crop morphotypes grown in Peru, Ecuador and Bolivia. This information is considered relative to the appearance of and growth data from two crop morphotypes grown in southern Illinois. Additionally, there is information from the South American documents on ecological considerations for M. expansa in Latin America, germplasm information, how the crop has been grown traditionally, preparation of roots and stems for consumption including reduction of astringency and use in traditional dishes and for animal feed, and use of the leaves for fodder. Brief consideration is given here to invasive and rare Mirabilis spp. and how this relates to introduction of M. expansa into new locations, along with information on disease and pests known for the crop. Discussion includes our considerations for conservation of the crop, and comparison of Andean crop yields with published yield data for comparable crops grown in the United States.

“…Con el paso del tiempo la región andina se ha visto enfrentada a diferentes problemas ambientales y sociales que se atribuyen al crecimiento de la agricultura, la deforestación y el mal uso de los recursos naturales (Izquierdo y Roca, 1998). A pesar de esto, la ecorregión andina aún cuenta con muchos recursos filogenéticos y una gran diversidad autóctona (Castillo, 1995).…”

Recuperación etnobotánica del uso tradicional no maderable del bosque secundario en el municipio de Nocaima, Cundinamarca. Ethnobotanical recovery of the traditional non-timber use of the secondary forest in Nocaima, Cundinamarca RESUMENEl uso tradicional no maderable del bosque secundario es importante para el bienestar rural y el manejo sostenible del recurso forestal; sin embargo, se ha ido perdiendo. Con la recuperación etnobotánica del uso tradicional no maderable del bosque secundario en el municipio de Nocaima se buscó identificar los puntos estratégicos relacionados con la presencia de bosque y sabedores locales, mediante entrevistas semiestructuradas, diálogos y recorridos guiados. La información se capturó por medio de grabaciones orales, fotografías y muestras botá-nicas identificadas en el herbario forestal UDBC. Se encontraron 161 especies pertenecientes a 68 familias, 126 de ellas nativas y 4 endémicas. El cálculo de los índices de importancia cultural, nivel de uso significativo, factor de consenso y nivel de fidelidad priorizaron 15 especies nativas para sistemas agroecológicos. Los porcentajes de uso tradicional no maderable encontrados para 10 categorías determinadas fueron: medicinal (57.8 %), alimenticia (28.6 %), ornamental (23.6 %), cultural (12.4 %), mágico-religiosa (8.7 %), cosmética (8.1 %), artesanal (6.2 %), forrajera (3.1 %), tintes (4.3 %) y protectora (4.3 %). En algunas categorías se encontraron nuevos reportes de uso. Por otra parte, la población entrevistada manifestó que un 86.9 % transmite el conocimiento sobre el uso a otras personas, mientras que un 89.1 % lo usa en su núcleo familiar; sin embargo el 65.2 % consideró que el conocimiento se perderá con el tiempo. Se concluyó que las categorías medicinal y alimenticia sobresalen entre los usos tradicionales no maderables del bosque secundario y se evidenció la importancia de estos usos en el núcleo familiar, aspecto que favorecerá la preservación y el uso sostenible de los bosques secundarios.
