Fatores pré-colheita que afetam a qualidade tecnológica de trigo

Abstract

A aptidão tecnológica representa uma oportunidade de agregar valor de mercado ao trigo, principalmente em face do mercado internacional e do setor industrial, o qual busca diferencial de qualidade aos seus produtos. Os fatores genéticos, meteorológicos e de manejo são determinantes para a obtenção da qualidade desejada. Nesse sentido, a adequada escolha da cultivar, o conhecimento das limitações climáticas da região de cultivo e da fertilidade do solo e a execução dos tratos culturais recomendados pela pesquisa podem contribuir substancialmente para a obtenção das características físicas, químicas e biológicas que conferem qualidade à farinha e aos produtos derivados de farinha, conforme abordado nesta revisão.

Effect of high and low molecular weight glutenin subunits, and subunits of gliadin on physicochemical parameters of different wheat genotypes

“…The T 091088, T 091031, and T 091027 lines, which stood out because of their higher protein content (>17%), were grouped together in quadrant I. According to Franceschi et al (2009), protein content has quantitative characteristics that are expressed by a large number of genes, which are influenced by the environment. Protein content may significantly vary for any given cultivar depending on the environmental conditions (climate and soil) in which the grain is cultivated, as well as on genetic control (TURNBULL; RAHMAN, 2002).…”

CD 1550 - bread wheat cultivar with high gluten strength for the cooler regions of Brazil

“…The development of new higher-yielding wheat cultivars is a constancy in wheat breeding programs, but according to Franceschi et al (2009), aside from satisfactory yields, the harvested wheat grain must also fulfill the technological quality standards of the processing or milling industry, thus avoiding the use of additives, for reasons of costs and food safety. The gene expression for processing or industrial quality of a particular wheat cultivar can be influenced by a number of environmental factors, e.g., soil fertilizer, management, environment, and grain harvesting, drying, storage, and milling.…”

Kernel chemical composition and flour quality of wheat in response to nitrogen sources and doses

“…Furthermore, quality dependents on genotype, environment (temperature, precipitation, soil fertility, etc. ), and interaction between genotype and environment (Franceschi et al, 2009). Changes in growing conditions not only affect grain yield, but also both physical and chemical parameters of the kernel (Souza et al, 2016;Prando et al, 2012).…”
