“…The obtained oils were identified by matching the obtained mass signals (spectra) with the standard mass spectra library in the GC-MS software. The retention time of the obtained compounds was confirmed by some of the normal alkanes that have been considered in published literatures [11,13,18,26,27].…”

“…For rose production, excess of sunlight, humid and moderate temperature is required, so optimum temperature range for roses is 15-25°C, relative humidity 55-80% and 5-8 hours sunlight [8,9]. Roses are growing wildly as an ornate plant and cherished for their fragrance as well as for their beauty [10,11]. Apart from its use for ornamental purpose they also show pharmacological (antidepressant, digestive, antiseptic, antioxidant, antiviral, antispasmodic and relaxant) properties [12][13][14].…”

“…Especially essential oil is most important part of rose plant being used. Among the huge variety of rose species R. damascene Mill., R. gallica L., R. moshata Herrm and R. centifolia L, by virtue of their illustrious as well as attractive fragrance, possesses paramount importance in essential oil production [10,11]. Consequently, these species are responsible for the production of essential oil on larger scale in many countries.…”

“…Se considerarmos todas as etapas de design, confecção, utilização em produtos e descarte/reciclagem de embalagens como um setor independente da produção de bens de consumo no Brasil, sua importância torna-se notória, uma vez que o faturamento das empresas desse setor em 2011 foi de R$ 43,7 bilhões [6] . Existem dois métodos de obtenção de nanoemulsões: os que empregam baixa e alta energia de emulsificação [7][8][9] . 486 Polímeros, vol.…”

Resumo: Neste trabalho, o objetivo foi produzir nanobiocompósitos biodegradáveis à base de pectina e nanoemulsão de canela que tenham propriedades satisfatórias para aplicação como embalagens ativas. Foram detalhados os procedimentos de preparação das nanoemulsões e incorporação dessas na matriz polimérica. Foi apresentada uma metodologia nova de análises dos melhores nanocompósitos através de um planejamento baseado em aspectos visuais que nos forneceu resultados interessantes. Os nanocompósitos obtidos foram analisados através de: medidas de espessura, solubilidade, propriedades mecânicas e microscopia eletrônica de varredura (MEV). Resultados das análises visuais mostraram que os nanocompósitos produzidos com concentração de pectina de 2% m/v e nanoemulsões preparadas com velocidade de agitação de 16000 rpm em 2 minutos mostraram melhores condições para serem aplicados como embalagens. Resultados de propriedades mecânicas demonstraram que nanocompósitos contendo nanoemulsões com tamanhos menores de gotículas apresentam maior resistência e elongação, além de serem menos solúveis. O controle dessas propriedades com a variação de tamanho médio das nanoemulsões torna esses materiais potencialmente viáveis, por exemplo, em embalagens ativas. Palavras-chave: Nanoemulsão, nanocompósito polimérico, pectina, óleo essencial de canela. Preparation of New Active Edible Nanobiocomposite Containing Cinnamon Nanoemulsion and PectinAbstract: In this study, the objective was to produce biodegradable nanobiocomposites based on pectin and cinnamon nanoemulsion having satisfactory properties for application as active packaging. Procedures for preparing and incorporating these nanoemulsions in the polymeric matrix are described. The nanocomposites were analyzed through: thickness measurements, solubility, mechanical properties and scanning electron microscopy (SEM). A subjective analysis indicated the nanocomposite made with pectin 2 % w/v and nanoemulsions prepared with stirring speed of 16000 rpm in 2 min was the most suitable for application in packaging. The nanocomposites containing nanoemulsions with smaller nanodroplets had greater strength and elongation, being less soluble. The control of these properties by varying the average size of the nanoemulsion makes these materials potentially viable, for example, for active packaging. Keywords: Nanoemulsion, polymeric nanocomposite, pectin, cinnamon essential oil. IntroduçãoA nanotecnologia é uma aplicação da nanociência que aparece praticamente em todos os setores da ciência. Na área de alimentos o elevado investimento na parte de embalagens tem reforçado a idéia de que produtos nanotecnológicos proporcionam vantagens reais aos consumidores [1,2] . De maneira bem didática podemos afirmar que a função primordial de uma embalagem é acondicionar o produto de forma a permitir todas as outras operações que fazem parte do processo de distribuição física, ou seja, levar o produto acabado até o cliente final. Complementando esta função temos que a embalagem do produto serve para a pro...

“…Turek and Stintzing [51] evaluated the impact of different storage conditions on four essential oils (lavender, pine, rosemary, and thyme) to verify the influence of light and temperature on their composition. The authors obtained interesting results, stating that parameters such as pH, conductivity, and the chemical profile of the essential oils are severely altered when exposed to light and temperature, which modifies their quality.…”

Cyclodextrin - A Versatile Ingredient

View full text Add to dashboard Cite

Many scientific studies have made advances in the ability to encapsulate natural extracts by cyclodextrins. These studies have addressed the physical and chemical conditions of the encapsulation reactions, employed several types of essential oils and characterized the microcapsules as to their ability to release encapsulated active principles. The essential oils studies with cyclodextrin encapsulation processes have been highly varied. However, the most studied are the essential oils with antimicrobial and antioxidant capacities. The essential antimicrobial and antioxidant oils are easily degraded. In the presence of oxygen, they are oxidized, and at low temperatures, they are volatilized and decomposed. Thus, cyclodextrins are coatings capable of protecting these essential oils from environmental conditions and agents capable of promoting oil degradation, in addition to controlling their release. In this chapter of the book, we review scientific papers that examine the encapsulation of antimicrobial essential oils and antioxidant essential oils with β-cyclodextrins.
