“…Essa realidade vem estimulando um grande número de pesquisas para o desenvolvimento de embalagens biodegradáveis a partir de fontes renováveis [1] . Entre os polímeros naturais, o amido tem se tornado um dos candidatos mais promissores para produção de biomateriais devido à combinação de preço atrativo, disponibilidade e renovabilidade [2] . O amido apresenta comportamento termoplástico, no entanto, ao ser utilizado puro, forma filmes quebradiços e com baixa flexibilidade.…”

Resumo: A característica hidrofílica dos biomateriais a base de amido resulta em alta instabilidade diante de diferentes condições ambientais. O amido de aveia, por possuir um conteúdo maior de lipídios em relação a outros amidos, tornase uma fonte interessante, uma vez que a hidrofobicidade aumentada pode atuar reduzindo sua capacidade de sorção de umidade. O objetivo do trabalho foi investigar o comportamento de filmes e laminados de amido de aveia, produzidos por casting e extrusão, respectivamente, plastificados com glicerol, sorbitol e ureia e armazenados em diferentes condições de umidade relativa. Mesmo com a presença do lipídio nativo, os materiais ainda mostraram instabilidade diante do aumento da umidade relativa de armazenagem, sendo observado um decréscimo na força e um aumento na deformação nos testes de perfuração. Em geral os biomateriais plastificados com glicerol apresentaram maior capacidade de sorção de água. O sorbitol foi o plastificante mais efetivo, pois produziu materiais com propriedades mecânicas similares aos outros plastificantes mesmo sendo usado em menor concentração molar. O processo de extrusão resultou em materiais finais com estruturas mais abertas e fragmentadas. Palavras-chave: Aveia, amido, plastificante. Effect of Processing and Enviromental Conditions in the Properties of Oat Starch Biodegradable MaterialsAbstract: The hydrophilic character of starch-based biomaterials generates high instability under different environmental conditions. Oat starch shows an interesting alternative for starch films because it contains higher lipid content than other common starches. This increased hydrophobicity can act reducing the moisture sorption capacity. The objective of this study was to investigate the behavior of oat starch films and sheets produced by casting and extrusion, respectively, plasticized with glycerol, sorbitol and urea and stored at different relative humidity. Even with the presence of native lipid, the materials still showed instability upon increasing the relative humidity for storage. Under higher humidity, a decrease in strength and an increase in deformation in puncture tests were observed. Biomaterials plasticized with glycerol showed higher water sorption capacity. Sorbitol was the most effective plasticizer because it led to materials with similar mechanical properties to other plasticizers even at lower molar concentrations. The extrusion process resulted in final materials with more open, fragmented structures.

“…The general subject area of packaging materials involving biomaterials has been the focus of numerous review articles and monographs (Lagaron et al 2004;Rhim and Ng 2007;Chiellini 2008;Johansson et al 2012;Tang et al 2012;Paunonen 2013a). For example, Krochta and DeMulderJohnston (1997) reviewed research related to edible and biodegradable films for packaging applications.…”

“…Secondly, the tiny dimensions of nanocellulose imply a high exposure to its surroundings. The issue of biodegradation has been emphasized in studies in which nanocellulose was used in composite structures with other natural film-forming materials (Lu et al 2008;Ma et al 2008;Cheng et al 2009;Wan et al 2009; Azeredo et al 2010;Bras et al 2010;Khan et al 2010Khan et al , 2012Khan et al , 2014bSiro and Plackett 2010;da Silva et al 2012;Hassan et al 2012;Johnsy and Siddaramaiah 2012;Tang et al 2012; Baheti and Militky 2013; ChingaCarrasco et al 2013;Ollier et al 2013; Bhardwaj et al 2014;Dehnad et al 2014a;Fortunati et al 2014;Ghaderi et al 2014;Khalil et al 2014;Kumar et al 2014;Marais et al 2014;Reddy and Rhim 2014;Song et al 2014;Yang et al 2014; Azizi Samir et al 2015; Feng et al 2015a;Figueiredo et al 2015;Honorato et al 2015;Lavoine et al 2015;Li et al 2015a;Lu et al 2015; Youssef et al REVIEW ARTICLE bioresources.com .

This review article was prompted by a remarkable growth in the number of scientific publications dealing with the use of nanocellulose (especially nanofibrillated cellulose (NFC), cellulose nanocrystals (CNC), and bacterial cellulose (BC)) to enhance the barrier properties and other performance attributes of new generations of packaging products. Recent research has confirmed and extended what is known about oxygen barrier and water vapor transmission performance, strength properties, and the susceptibility of nanocellulose-based films and coatings to the presence of humidity or moisture. Recent research also points to various promising strategies to prepare ecologically-friendly packaging materials, taking advantage of nanocellulose-based layers, to compete in an arena that has long been dominated by synthetic plastics. Some promising approaches entail usage of multiple layers of different materials or additives such as waxes, high-aspect ratio nano-clays, and surface-active compounds in addition to the nanocellulose material.While various high-end applications may be achieved by chemical derivatization or grafting of the nanocellulose, the current trends in research suggest that high-volume implementation will likely incorporate water-based formulations, which may include water-based dispersions or emulsions, depending on the enduses.

As of November 2016, a search of this combination of terms showed about as many publications since the start of 2015, compared to all preceding years combined. Given such an acceleration of research around the world, it makes sense to ask whether this high amount of research effort has yet borne significant fruit. In light of this question, the emphasis of this review article is on research publications that shed light on known challenges to the successful implementation of nanocellulose products to enhance the performance of packaging.In principle, a nano...

“…Starch can show a thermoplastic behavior if water, glycerol or sorbitol is added as plasticizer. In spite of its many advantages, starch based materials have severe disadvantages due to poor processability, weak mechanical properties, poor long-term stability and high water sensitivity [5,9].…”

“…A clear example is the use of cellulose obtained from plants that has been investigated for several decades [4]. Tang et al, [5] distinguished two kinds of biopolymers: those that come from living organisms and those which need to be polymerized but come from renewable resources and are biodegradable. Taking into account this classification, the first group includes polysaccharide (chitosan, starch, cellulose, among others) and protein (gelatin, collagen, keratin, etc.…”

Abstract:The performance as reinforcement of a fibrillar protein such as feather keratin fiber over a biopolymeric matrix composed of polysaccharides was evaluated in this paper. Three different kinds of keratin reinforcement were used: short and long biofibers and rachis particles. These were added separately at 5, 10, 15 and 20 wt% to the chitosan-starch matrix and the composites were processed by a casting/solvent evaporation method. The morphological characteristics, mechanical and thermal properties of the matrix and composites were studied by scanning electron microscopy, thermogravimetric analysis, differential scanning calorimetry and dynamic mechanical analysis. The thermal results indicated that the addition of keratin enhanced the thermal stability of the composites compared to pure matrix. This was corroborated with dynamic mechanical analysis as the results revealed that the storage modulus of the composites increased with respect to the pure matrix. The morphology, evaluated by scanning electron microscopy, indicated a uniform dispersion of keratin in the chitosan-starch matrix as a result of good compatibility between these biopolymers, also corroborated by FTIR. These results demonstrate that chicken feathers can be useful to obtain novel keratin reinforcements and develop new green composites providing better properties, than the original biopolymer matrix.
