Êste trabalho, que reune resultados de ensaios de secagem efetuados em Campinas pelo processo de ar quente, em um secador em forma de túnel yertical, semi-industrial e especialmente construido para êsse fim, representa uma contribuição para o estudo da desidratação de diversos dos nossos alimentos. Observou-se que os produtos amiláceos, tais como batatinha (Solanum tuberosum L.), cenoura (Daucus carota L. var. sativa D.C.), ervilhas (Pisum sativum L.), mandioca (Manikot utilissima Pohl) e mandioquinha (Arracacia xanthorrhiza Bancr.) podem ser sêcos entre 40 e 55°C de temperatura, em tempo variável de 5-10 horas, conforme a densidade de distribuição do material nas bandejas do secador. O feijão guandu (Cajanus cajan L. Millsp.) bem como a batata doce (Ipomoea batatas Lam.) constituíram exceção ao tempo de secagem, levando 15 horas para secar.

Emulsifiable Concentrate

Dyfonate (O-ethyl S-phenyl ethylphosphonodithioate) was incorporated into soil at the rate of 5.6 or 11.2 kg/ha as granules or emulsifiable concentrate and its persistence in soil and its absorption by potatoes (Solanum tuberosum L.), carrots (Daucus carota L.), beets (Beta vulgaris L.), rutabagas (Brassica napobrassica (L.) Mill), and wheat (Triticum aestivum L.) plants were studied in four locations in Saskatchewan. Proportionately more residue persisted in the soil from the higher rate of application. About 33–35% of the Dyfonate applied as granules at the lower rate remained in the soil 4 mo after application, whereas about 38–41% remained from the emulsifiable concentrate. At the end of the same period, 52–64% of the granules applied at the higher rate remained in the soil as compared to 50–71% from the emulsifiable concentrate. Only 3–10% of the applied chemical remained in the soil 29 mo after application. No residue of dyfoxon (O-ethyl S-phenyl ethylphosphonothioate) was detected in any soil. Potatoes, beets and rutabagas harvested 4 mo after application of Dyfonate had little (0.005 to 0.009 ppm) or no detectable (less than 0.005 ppm) residue, irrespective of the rate of application. Wheat seedlings had between 0.01–0.07 ppm Dyfonate and little or no detectable residue in the more mature plant or in the grain. Carrots grown in soil treated at the lower rate had about 0.35 and 0.04 ppm Dyfonate and dyfoxon, respectively, and at the higher rate, 0.81 and 0.06 ppm. About 77–94% of the residues in carrots could be removed by peeling.

Chlorfenvinphos (diethyl 1-(2,4-dichlorophenyl)-2-chlorovinyl phosphate) applied broadcast to field plots at 5.6 kg/ha a.i. (56 kg/ha Birlane 10G) 4 days prior to seeding resulted in traces of the parent compound in beets (Beta vulgaris L.), potatoes (Solanum tuberosum L.), carrots (Daucus carota var. sativa DC.), parsnips (Pastinaca sativa L.), and rutabagas (Brassica napobrassica Mill.) at harvest. The α isomer was found in all crops except beets at ~ 0.01 ppm. The β isomer was found in all crops with carrots and parsnips containing 0.09 and 0.06 ppm, respectively. Chlorfenvinphos residue concentrations in treated soil declined ~ 73% during the 23-wk growing season following pesticide application, but trace residues were detected in the soil 4 yr after application.

Daucus Carota L

The behavior of people who less consume vegetables and fruit can have a negative impact on health. The lack of appetite for vegetable consumption by the society made the researchers interested in making a combination of vegetables, namely carrots with local foods, namely Baroncong.This research aims to determine the acceptability of local baroncong snacks with the addition of carrots.This research is a pre-experimental study. The panelists from this study consisted of 30 Nutrition Department Students from Health Polytechnic Ministry of Health Makassar. Assessment based on taste aspects, color of aroma and texture of baroncong products with the addition of carrots 50%, 75%, 100% with the criteria of very like, like, dislike and very dislike.The results showed that the acceptability of baroncong with the addition of carrots in terms of taste was a concentration of 75%, which was very much as much as 46.7% and liked as much as 50%, the color aspect was 50% concentration consisting of 36.7% likes and likes as much as 53.3%, the aroma aspectis a concentration of 50% which consists of very much as much as 33.3% and likes as much as 63.3%, in terms of aspects of texture are concentrations of 50% and 75%, each of which consists of as much as 23.3% and likes as much as 63, 3%. Based on these data, Baroncong with the addition of carrots received is a concentration of 75%.

Objetivo: Establecer una línea base como fundamento para la intervención e inducción de innovaciones a través de escuelas de campo y planes de negocios. Diseño/metodología/aproximación: El estudio se desarrolló en San José del Carmen, San Cristóbal de Las Casas, Chiapas, México. Se elaboró una encuesta como instrumento para recabar en campo información de familias de la localidad con la finalidad de conocer su situación actual. La localidad de trabajo se eligió utilizando como criterio las poblaciones que se encuentran dentro de Cruzada Nacional contra el hambre y en la clasificación de la pobreza extrema Resultados: La localidad de San José del Carmen es considerada como de alta marginación, la población es bilingüe, su principal lengua es el Tzotzil, el nivel de estudios promedio es hasta el tercer año de primaria, las principales actividades productivas son la siembra de maíz (Zea mays L.), frijol (Phaseolus vulgaris L.), papa (Solanum tuberosum L.) y haba (Vicia faba L.) que son utilizadas principalmente para autoconsumo.  No cuentan con agua potable ya que su sistema es a través de la recaudación de agua de lluvia o a través de un jagüey. Sus principales actividades económicas son la albañilería por parte de los hombres, y venta de productos, tales como el pozol (bebida energética a base de maíz y cacao (Theobroma cacao L.), tostadas y algunos vegetales por parte de las mujeres. Las tostadas son producidas en forma artesanal con un proceso de doble nixtamalización y vendida en bolsas de 20 tostadas cada una, a un costo de MX$10.00 en los mercados de San Cristóbal de las Casas, una a dos veces por semana alrededor de 40 bolsas por día de venta. Limitaciones del estudio/implicaciones: La afiliación zapatista de alguno de los pobladores y el hecho de que algunos habitantes no hablen español, fueron factores que limitaron desarrollar al 100% el estudio; sin embargo, se considera que se tienen los elementos necesarios para establecer la línea base de la situación de San José del Carmen. Conclusiones: El diagnóstico servirá como una herramienta para establecer una intervención a través de innovaciones y planes de negocios en la comunidad de estudio. Los pobladores cuentan con herramientas necesarias para obtener nuevos conocimientos que ayuden a un desarrollo de su producción. El idioma no deberá de ser una limitante para ello.
