1. Use of post-harvest films for the maintenance of the visual attributes and ethylene production of ornamental mini-pumpkins
Resumo Nos últimos anos, o mercado consumidor tem mostrado interesse no uso ornamental de alguns frutos que anteriormente eram empregados principalmente para fins alimentares. No entanto, o uso das chamadas ‘mini-abóboras’ para ornamentação pode ser limitado por aspectos ligados à pós-colheita, como despigmentação da casca, perda de massa fresca,

2. Starch Films Added of Açaí Pulp ( Euterpe oleracea Martius)
ABSTRACT Edible films are an alternative to synthetic materials used for packaging foods. The aim of this study was to develop and characterize films made from cassava starch, freeze-dried acai and glycerol. The films were characterized for thickness, water vapor permeability, water solubility, anthocyanins, antioxidant capacity and mechanical properties. Th

3. Production of biodegradable starch nanocomposites using cellulose nanocrystals extracted from coconut fibers
Abstract Different polymeric matrices have been investigated for use in the development of biodegradable films. The incorporation of cellulose nanocrystals in such films has particularly attracted attention because of the potential for achieving improved properties of starch nanocomposites. In the present study, cellulose nanocrystals were extracted from coc

4. Analysis of Water Barrier, Mechanical and Thermal Properties of Nanocoposites Based on Cassava Starch and Natural Clay or Modified by Anionic Exchange
Biopolymer films have several industrial applications because they are environmentally sustainable. Cassava starch is a biopolymer that is easily available, but has limitations: it is hydrophilic, poorly resistant and degradable. The improvement of these properties was proposed in this research from the use of bentonite clay (BT) as a filling material. The c

5. Effect of the Glycerol and Lignin Extracted from Piassava Fiber in Cassava and Corn Starch Films
Several alternatives have been considered to minimize the environmental impact caused by conventional polymers. This study aims to evaluate the chemical, mechanical and morphological properties of flexible thermoplastic films of cassava and corn starch, using glycerol and lignin as plasticizers and reinforcement. The films were produced through casting. It w

6. Obtenção de nanocelulose da fibra de coco verde e incorporação em filmes biodegradáveis de amido plastificados com glicerol
Composites strengthened with nanocellulose have been developed with the aim of improving mechanical, barrier, and thermal properties of materials. This improvement is primarily due to the nanometric size and the high crystallinity of the incorporated cellulose. Cassava starch films plasticized with glycerol and incorporated with nanocellulose from coconut fi

7. Starch/polyester films: simultaneous optimisation of the properties for the production of biodegradable plastic bags
Blends of starch/polyester have been of great interest in the development of biodegradable packaging. A method based on multiple responses optimisation (Desirability) was used to evaluate the properties of tensile strength, perforation force, elongation and seal strength of cassava starch/poly(butylene adipate-co-terephthalate) (PBAT) blown films produced vi

8. Caracterização físico-química de filmes comestíveis de amido adicionado de acerola (Malphigia emarginata D.C.)
Edibles films are an alternative to synthetic materials used for packing food products. Barbados cherry is rich in vitamin C and carotenoids. The aim of this study was to characterize and develop films by casting from cassava starch, lyophilized Barbados cherry pulp and glycerol. The films were characterized with respect to thickness, water vapor permeabilit

9. Filmes de amidos de mandioca modificados para recobrimento e conservação de uvas
In this article, films were produced with six types of cassava's starch mixed with gelatin and plasticized with sorbitol. These films were used in covering of grapes 'Benitaka' (Vitis vinifera L.) as biodegradable packaging. The acetylated starch film showed the best results in solubility, thickness and homogeneity, besides the less water loss the fruit, res

10. Chemical and physical characterization of cassava flour and soy protein biofilms. / Caracterização físico-química de filmes biodegradáveis de farinha de mandioca e proteína de soja.
Environmental concerns associated with plastics disposal have promoted research into alternatives to replace the common plastic. Following this tendency, this research used cassava flour mixed with different rates of soybean protein and glycerol to produce biodegradable films by thermoplastic extrusion. Variables analyzed were: soybean protein, moisture and

11. Emulsificantes com diferentes EHL (Equilíbrio hidrofílico-lipofílico) em filmes de amido de mandioca
The exhaustion of petroleum world wide reserve and the preoccupation with the enviromental preservation have served as incentive for the development of biodegradable films. Cassava starch is widely produce in the brazilian industry and present characteristics that allow the use of this agropolymer as raw material for this finality. As a way to improve film s
