Desenvolvimento e caracterização de bioplásticos de amido de milho contendo farinha de subproduto de broto

Abstract: Resumo O objetivo deste trabalho consistiu em desenvolver e caracterizar filmes biodegradáveis de amido de milho contendo farinha de subproduto de broto. Para isso, foi desenvolvida uma farinha a partir de diferentes tipos de broto (feijão, alfafa, amaranto, brócolis, rabanete e, predominantemente, trevo) e realizada sua caracterização tecnológica. Primeiramente, foi produzida farinha de subprodutos de brotos com uso de circulação forçada de ar a 50 ºC. As análises físico-químicas demonstraram que a farinha el… Show more

“…The high flour/fiber concentration of the macaúba epicarp made the film more porous, which could lead to phase separation (Zimmermann et al, 2014 [ 53 ]). These findings are congruent with previous results, such as those by [ 49 ], who observed a leveled and continuous surface in macaúba mesocarp flour films with glycerol and clove oil as plasticizers, although they still had some porosity. Other studies, such as Maniglia and Tapia-Blácido (2016), who developed biopolymers based on babassu coconut mesocarp starch, identified predominantly smooth granules, but some areas exhibited granular surfaces due to proteins, lipids and fibers present.…”

“…Those parameters were used to calculate Chroma ( c *) that correspond to the color intensity, and Hue or Hue angle ( h *) that corresponded to the color tone expressed in degrees (0° – red, 90° – yellow, 180° – green, and 270° – blue). [ 23 ] The calculations were performed according to: hbadbreak=tan1()b/a$$\begin{equation}{h^*} = ta{n^{ - 1}}\left( {b*/a*} \right)\end{equation}$$ cbadbreak=a2+b2$$\begin{equation} {c^*} = \sqrt {\left( {{a^2} + {b^2}} \right)} \end{equation}$$…”
