摘要：
Use of edible films based on vegetable hemicelluloses and wax in fruit preservation The present invention is based on the use of biodegradable films based on vegetable hemicelluloses and wax applied to whole fruits improving their preservation. Polysaccharide-based films are colorless and have good gas and water vapor permeability properties. Biodegradable films formed by polysaccharides and lipids with satisfactory mechanical and appearance properties are potential and ecological alternatives to the use of synthetic packaging. Therefore, newly developed films are focused on combining the matrix polymer with some hydrophobic component. Caesalpinea pulcherrima seeds were used for the extraction of galactomannan (polysaccharide) through grinding, water swelling, filtration and drying processes to obtain the powder. The lipid used was carnauba wax t-1. A central composite design was used to evaluate the effect of proportions between 2 components: carnauba wax (0.3-0.9% w / w) and glycerol (15-20% mlv) - on properties. of the formed films. The percentage of galactomannan was set at 0.75% w / v. The design consisted of 11 trials. The films were evaluated for water vapor permeability, water solubility and opacity and generally the best treatments were o4eo5.uso de filmes comestíveis à base de hemiceluloses vegetais e cera na conservação de frutos a invenção apresentada baseia-se no uso de filmes biodegradáveis à base de hemiceluloses vegetais e cera com aplicação em frutos íntegros melhorando a conservação dos mesmos. filmes à base de polissacarídeos são incolores e apresentam boas propriedades de permeabilidade aos gases e vapor de água. filmes biodegradáveis formados por polissacarideos e lipídios com propriedades mecânicas e de aparência satisfatórias são alternativas potenciais e ecológicas ao uso de embalagens sintéticas. portanto, os filmes recém-desenvolvidos estão focados em combinar o polímero matriz com algum componente hidrofóbico. utilizou-se sementes de caesa
