TEXTURE PROFILE OF FILMOGENIC SOLUTIONS WITH POTENTIAL APPLICATION FOR SEED BIODEGRADABLE COATINGS / PERFIL DE TEXTURA DE SOLUÇÕES FILMOGÉNICAS COM POTENCIAL APLICAÇÃO DE REVESTIMENTOS BIODEGRADÁVEIS DE SEMENTES

Seed coating has been used in order to minimize environmental and human health damage generated by the use of conventional treatments. Therefore, the aim of this work was to evaluate the influence of the contents of cassava starch (0.5 and 5% (m m -1 )), glycerol (5 and 50% (m m -1 )) in relation to the starch mass, and pH (5.5 and 6.5) on the texture parameters (hardness, adhesiveness, fracture, cohesiveness, elasticity and gumminess) of filmogenic solutions with the potential to prepare seed coatings. The adhesiveness, cohesiveness, elasticity and gumminess, were influenced by the variables in the studied range. In order to evaluate the coatings produced on seed germination, future work is necessary.
