| Two field experiments were conducted during two successive seasons (2014/2015 and 2015/2016) at the Experimental Station of National Research Centre, Nubaria district, Beheira Governorate, Egypt, to study the effect of foliar treatment of quinoa plants with trehalose (Tre) (100µM and 500µM) on growth, photosynthetic pigments, seed yield quantity & quality, in fever of nutritional and antioxidant compounds in the yielded quinoa seeds which subjected to water deficiency (skipping two irrigation times at 50 & 60 days after sowing). Water deficiency caused marked decreases in quinoa plant growth parameters (shoot height, fresh and dry weights of shoot/plant) and photosynthetic pigments with marked increases in root growth parameters (root length, fresh... |

| La semilla de quinoa (Chenopodium quinoa Willd) se caracteriza por presentar una composición balanceada; es rica en proteínas, fibra, vitaminas, minerales y antioxidantes, por lo que puede ser incorporada en la formulación de barras de cereal a fin de incrementar el valor nutricional de la alimentación diaria. El objetivo de este trabajo fue estudiar el efecto de la incorporación de semillas de quinoa en la calidad tecnológica, nutricional y sensorial de barras de cereal. Se elaboraron y analizaron tres muestras de barras de cereal, con diferentes porcentajes de sustitución de arroz crocante por semillas de quinoa y un control (sin quinoa). Se observó un incremento de peso de las barras de cereal, a medida que se aumentó el nivel de sustitución y una... |

| Se describen los efectos de la UV-B sobre la síntesis de pigmentos fotosintéticos (clorofila total, clorofila a, clorofila b, carotenoides), protectores (compuestos absorbentes de UV-B) y azúcares solubles (glucosa, fructosa y sacarosa) en cinco variedades de quinoa de diferentes orígenes geográficos. En general, se demuestra que las variedades reaccionan desplegando diferentes estrategias para protegerse de la radiación UV-B. Estas estrategias pueden ser de tipo morfológico, fisiológico y/o bioquímico. Una respuesta común, observada en las cinco variedades fue el incremento en el contenido de compuestos absorbentes de UV-B, lo que puede interpretarse como un "escudo químico" de protección para el aparato fotosintético frente al exceso de energía... |

| Drying kinetics of quinoa-supplemented feed for laboratory rats during processing at 50, 60, 70, 80 and 90ºC was studied and modeled in this work. Desorption isotherm was obtained at 60ºC giving a monolayer moisture content of 0.04 g water/g d.m. The experimental drying curves showed that drying process took place only in the falling rate period. Several thin-layer drying equations available in the literature were evaluated based on determination coefficient (r²), sum squared errors (SSE) and Chi-square (χ2) statisticals. In comparison to the experimental moisture values, the values estimated with the Logarithmic model gave the best fit quality (r² >0.994, SSE < 0.00015 and χ2 < 0.00018), showing this equation could predict very accurately the... |

| Insects are attracted to plants by visual and olfactory cues. The quinoa moth, Eurysacca melanocampta Meyrick (Lepidoptera: Gelechiidae), is the main insect pest of the quinoa crop, Chenopodium quinoa Willd. (Chenopodiales: Chenopodiaceae), in the southern Peruvian Andes, causing grain yield losses. The aim of this study was to investigate the behavioural response of adult quinoa moths to olfactory stimuli. Specifically, the objectives of this study were: 1) to determine the capacity of E. melanocampta adults of searching for quinoa plants using plant olfactory cues; 2) to determine the preference of E. melanocampta females for the odours derived from two varieties of quinoa: Amarilla de Marangani and Blanca de Junín; and 3) to assess the attraction of... |

| This study explored the diversity of the quinoa crop in Chile from a nutritional perspective. Nutritional properties, minerals, vitamins, and saponin content were assessed in seeds of six Chilean quinoa (Chenopodium quinoa Willd.) ecotypes grown in three main production areas with distinctive climatic and edaphic conditions: Ancovinto and Cancosa in the North-Altiplano or High Plateau, Cáhuil and Faro in the central coastal area, and Regalona and Villarrica in the south of the country. There were significant differences (P < 0.05) in all the nutritional properties of the quinoa seeds in all three areas. Quinoa of the Villarrica ecotype showed the highest protein content (16.10 g 100 g-1 DM) and the highest content of vitamins E and C (4.644 ± 0.240 and... |

| Quinoa is considered a pseudocereal with proteins of high biological value, carbohydrates of low glycemic index, phytosteroids, and omega-3 and 6 fatty acids that bring benefits to the human health. The purpose of this study was to investigate the effects of quinoa on the biochemical and anthropometric profile and blood pressure in humans, parameters for measuring risk of cardiovascular diseases. Twenty-two 18 to 45-year-old students were treated daily for 30 days with quinoa in the form of a cereal bar. Blood samples were collected before and after 30 days of treatment to determine glycemic and biochemical profile of the group. The results indicated that quinoa had beneficial effects on part of the population studied since the levels of total cholesterol,... |

| Four varieties of an Andean indigenous crop, quinoa (Chenopodium quinoa Willd.), were evaluated as a source of dietary fiber, phenolic compounds and antioxidant activity. The crops were processed by extrusion-cooking and the final products were analyzed to determine the dietary fiber, total polyphenols, radical scavenging activity, and in vitro digestibility of starch and protein. There were no significant differences in the contents of total dietary fiber between varieties of quinoa. In all cases, the contents of total and insoluble dietary fiber decreased during the extrusion process. At the same time, the content of soluble dietary fiber increased. The content of total phenolic compounds and the radical scavenging activity increased during the extrusion... |

| Abstract The study aimed to assess the influence of quinoa flour of different particle size and degree of wheat flour replacement on dough and bread characteristics. Dynamic rheology and farinographs were used to describe the dough parameters. Specific volume, texture, porosity, color, overall quality and chemical assessment were performed as well. It could be observed that the degree of wheat flour substitution by quinoa flour significantly influenced the G’ and G” values in linear and quadratic terms (p ≤ 0.01 and p ≤ 0.05). Particle size played a significant role in increasing G’ and G” only in quadratic terms. Increasing quinoa substitution of wheat flour and interaction of PS and QS significantly increased the porosity of breadcrumbs. Moisture content... |

| The present study was focused on the analysis of agronomical, nutritional, physicochemical, and antioxidant properties of six genetically different quinoa (Chenopodium quinoa Willd) genotypes cultivated in three distinctive geographical zones of Chile. Ancovinto and Cancosa genotypes from the northern Altiplano (19 ºS), Cáhuil and Faro from the central region (34 ºS), and Regalona and Villarica from the southern region (39 ºS) are representative of high genetic differentiation among the pooled samples, in particular between Altiplano and the central-southern groups. A Common-Garden Assay at 30 ºS showed significant differences among seed origins in all morphometric parameters and also in yields. Altiplano genotypes had larger panicule length but no seed... |

| Este trabalho é o resultado de esforços envidados pelos pesquisadores, seus colaboradores e parceiros, com a finalidade de diversificar a produção de grãos. Os problemas fitossanitários crescentes, como resultado do monocultivo, precisam de solução. Como os autores mencionam, temos de imitar a natureza em sua diversidade, ainda que, do ponto de vista prático, o desafio seja grande. No Bioma Cerrado e no Brasil, predomina o plantio direto, por uma série de vantagens ao produtor, com conseqüências favoráveis ao meio ambiente. Entretanto, como em todos os desafios, a agricultura precisa de aprimoramento para contornar os reveses de sua prática em sistemas monoculturais. Novos problemas podem resultar das ações ligadas ao plantio direto. O não-revolvimento do... |
