Estudo comparativo da caracterização de filmes biodegradáveis de amido de mandioca contendo polpas de manga e de acerola

Abstract: Recebido em 2/12/10; aceito em 3/7/11; publicado na web em 16/8/11 COMPARATIVE STUDIES ON THE CHARACTERIZATION OF BIODEGRADABLE CASSAVA STARCH FILMS CONTAINING MANGO AND ACEROLA PULPS. Most compounds reinforcements have been used to improve thermals, mechanical and barrier properties of biopolymers films, whose performance is usually poor when compared to those of synthetic polymers. Biodegradables films have been developed by adding mango and acerola pulps in different concentrations (0-17,1% w/w) as antioxid… Show more

“…Because of this result, films were prepared as double layers. Thickness values were higher than some of those reported in the literature, such as films based on bacterial cellulose and potato starch (0.020–0.078 mm) or cassava starch films containing mango and acerola pulp (0.123–0.140 mm) …”

“…Ressalta-se ainda que as ótimas propriedades mecânicas apresentadas pelos filmes (A, B, CA e CB) estão relacionadas à presença dos nanocristais de celulose de coco, como relatado por outros autores que também incorporaram nanocristais de celulose de diferentes fontes em matrizes poliméricas biodegradáveis (WANG et al, 2006;CAO et al, 2008). SOUZA et al (2012) relatam valores bastante inferiores para a tensão (1,85 a 4,81MPa) de filmes de amido sem a presença de nanocristais de celulose. Além disso, os valores de resistência à tração encontrados no presente estudo são semelhantes aos relatados para filmes sintéticos de polietileno de baixa densidade (PEBD), que variam de 6,9 a 16MPa (COUTINHO et al, 2003).…”

“…The commonly used films are polyethylene, polypropylene, and various polymers (Neves et al, 2002;Sanches et al, 2011). However, environmental reasons associated with new trends in the consumer market have led the food industry to engage , Maria Lucia NUNES 2 , Marília Dliveira Fonseca GDULART in the development of nature friendly materials with a lower environmental impact (Lorevice et al, 2014;Souza et al, 2012;Mali et al, 2010;Farias et al, 2012).…”

“…) and lipids (waxes and lipid derivatives) (Fakhouri et al, 2007). However, the commercial use of edible films formulated from the usual biodegradable matrices has been limited by problems related to the usually poor mechanical properties and poor moisture barrier compared to synthetic polymers (Souza et al, 2012).…”
