We have prepared a review of the physical-chemical composition and the functional and anti-nutritional properties of quinoa (Chenopodium quinoa Willd.). It is a plant of the Chenopodiaceae family, originally from the Andean regions, adaptable to different types of soils and climatic conditions. Its composition has attracted the attention of scientific community for its high nutritional value, being rich in proteins, lipids, fibers, vitamins, and minerals, with an extraordinary balance of essential amino acids. It is also gluten-free, a characteristic that enables its use by celiac patients. In spite of all these attributes, quinoa is not widely used by consumers due to the high cost of imported grain and little knowledge of its benefits. More studies are required to increase knowledge about this "pseudo-cereal" to demonstrate its functional and nutritional benefits and to study its anti-nutritional effects, since it presents high commercial value and excellent nutritional quality.

O objetivo do presente trabalho foi avaliar a viabilidade tecnológica e sensorial do uso da farinha de aveia em mistura com farinha de trigo (0, 15, 30 e 45% de adição) na elaboração de bolos. A farinha de aveia apresentou maior granulometria que a de trigo, de modo que maior quantidade dessa farinha nas formulações eleva a retenção de partículas nas peneiras utilizadas. Foi observado pela análise farinográfica que a absorção de água e o tempo necessário para formação de massa homogênea e estável às condições de mistura aumentaram com o incremento no teor de farinha de aveia. A densidade das massas cruas aumentou com a adição da farinha de aveia, sendo o oposto observado para o volume do bolo. A análise sensorial revelou que as formulações com 0% e 30% de farinha de aveia foram as mais aceitas pelos consumidores. O emprego de 30% de farinha de aveia não modificou a aceitação dos atributos sabor, textura e impressão global do bolo, sendo viável a utilização dessa porcentagem para substituição parcial da farinha de trigo na elaboração de bolos.

a b s t r a c tThis study evaluated the effect of addition of modified starch on the characteristics of dulce de leche, being conducted in two phases. In the initial phase, starches were evaluated for their ability to provide viscosity in model solutions representing the composition of dulce de leche during processing, thus evaluating the effect of solid concentration, which occurs during production, on the ability of starches to increase viscosity in simulated conditions of heat treatment and agitation promoted by Rapid Visco Analyser (RVA). It has been chosen 2 starches and 2 concentrations of soluble solids from the results of the initial phase, being employed as a criterion of choice starches with the highest viscosities at each solid concentration processing phase. In the second stage, 6 treatments were applied in triplicate, in which it's been determined the chemical composition, the instrumental color, texture profile and yield. Analyses were performed on crystallization of lactose during storage. According to the established conditions of the experiment, the starch configures itself as an important optional ingredient for the production of dulce de leche providing then longer shelf life without change in texture, composition, yield and sensory characteristic.
